What is rapid prototyping?
Rapid prototyping is a kind of professional manufacturing technology that is used to produce high-quality entity models of three-dimensional designs. Prototypes are useful for design improvements and can be used as stepping stones for comprehensive production or engineering testing. With the rapid prototyping china, you can manufacture parts or the products to test for the component fit and function. According to the analysis results, you can make further adjustments (about the design, shape, materials, etc.) before the products finally enter the market. It can help you effectively save time and costs. A lot of our customers need to manufacture a entity component quickly to verify the feasibility of a design or a part. Nowadays, various kinds of rapid prototyping processes are available. You can choose the process which best suits your needs. With only thirty years around of development, rapid prototyping technology, as its name implies, has already been widely used in many areas. Meanwhile, the rapid prototyping services are still growing at a fast speed.

Different Rapid Prototyping Processes

Prototypes can be made through different rapid prototyping processes. With thirty years around of development, a variety of prototype manufacturing processes are available. In addition, they are continuing to evolve. Since companies or customers have different requirements and demands, different types of rapid prototyping processes will be chosen. So how does rapid prototyping work? Reading the following contents and you will know which rapid prototyping service suits you best.

 

SLA（StereoLithography）

• Description: SLA is a photo-curing molding technology, which refers to the method of forming three-dimensional solid layer by layer through the polymerization reaction of liquid photosensitive resin by ultraviolet irradiation. The work piece prepared by SLA has high dimensional accuracy and is the earliest commercial 3D printing technology.
• Printing Material: Photosensitive Resin
• Strength: photosensitive resin is insufficient in toughness and strength and is easily broken. At the same time, under high temperature conditions, the printed parts are easy to bend and deform, and the bearing capacity is insufficient.
• Features of finished product: SLA printed workpieces have good details and smooth surface, which can be colored by spray painting and other processes.

 

Selective Laser Sintering (SLS)

• Description:SLS is a selective laser sintering technology, similar to SLM technology. The difference is the laser power. It is a rapid prototyping method that uses infrared laser as a heat source to sinter powder materials and form three-dimensional parts layer-by-layer.
• Printing Material:Nylon powder, PS powder, PP powder, metal powder, ceramic powder, resin sand and coated sand (common printing materials: nylon powder, nylon plus glass fiber)
• Strength:material performance is better than ABS products, and the strength and toughness are excellent.
• Features of finished product:the finished product has superior mechanical properties and is suitable for direct production of measurement models, functional models and small batch of plastic parts. The disadvantage is that the precision is not high, the surface of the prototype is relatively rough, and it is generally required to be polished by hand, sprayed with glass beads, ash, oil and other post-processing.

Fused Deposition Modeling (FDM)

• Description: FDM is a melt lamination technology, that uses high temperature to melt materials, extrudes them into filaments through the print head, and builds up on component platform. FDM is the simplest and most common 3D printing technology, which is commonly used in desktop 3D printing devices.
• Printing Material：usually ABS or PLA wire
• Strength: PLA is brittle,its surface hardness is higher, and it is easier to break when bending. ABS parts are more resilient than PLA parts, and are easy to bend rather than break under pressure. Moreover, ABS has higher strength, better plasticity, and easier post-processing.
• Features of finished product: the printing layer is thick, the precision is poor, and the stratification of the surface is very obvious. Under high temperature conditions, the printed parts are easy to bend and deform, and the bearing capacity is insufficient.

 

CNC

• Description: CNC machining is a subtractive manufacturing process in which the software control system issues instructions to make the tool perform various required movements. In this process, various precision tools are used to remove the raw materials and make parts or products.
• Materials: CNC processing materials are quite extensive, including plastics and metals. Plastic hand model materials are: ABS, acrylic, PP, PC, POM, nylon, bakelite, etc.; Metal hand model materials are: aluminum, aluminum Magnesium alloy, aluminum zinc alloy, copper, steel, iron, etc.
• Strength: different materials have different strengths and are difficult to list
• Features of finished product: CNC machined parts have a smooth surface, high dimensional accuracy, and the best compactness, and there are a variety of post-processing options.

 

Vacuum Casting

• Description: vacuum casting technology is to use the prototype (rapid prototyping parts, CNC hand parts) to make a silicone rapid prototyping mold under vacuum condition. It also uses PU, ABS and other materials to pour, so as to clone the same copy with the product prototype.
• Material: ABS, PU, PVC, silicone, transparent ABS
• Strength: the strength and hardness are lower than the CNC hand parts. Common PU material is relatively brittle, toughness and high temperature resistance are poor. ABS has higher strength, better plasticity, and easier post-processing.
• Features of finished product: easy to shrink and deform; the accuracy is generally only 0.2mm. In addition, the vacuum casting hand parts can only resist high temperature of about 60 degrees, and is lower than CNC hand parts in strength and hardness.

 APPLE JUICE

Apple juice in the press process will bring a lot of impurities in pulp, pectin, starch, plant fiber, microorganisms, bacteria, and other impurities. Thus, it's not easy to produce apple juice concentrate through traditional methods. Due to high sugar content in apple juice, microorganisms and bacteria are easy to breed which makes apple juice fermentation ferment and deteriorate. 

High-temperature sterilization will result in product discoloration and loss of flavor. The traditional filtration methods (diatomaceous earth, framed filter) can not completely retain the impurities, can play a temporary clarification. Under the influence of time, temperature, charge,re-flocculation of dissolved impurities form visible matters, resulting in apple juice turbidity and precipitation.

Macromolecular impurities such as plant fiber, starch, bacteria and other impurities in apple juice are completely intercepted to realize the clarification and impurity removal of apple juice by crossflow microfiltration.

Cross-flow design is adopted to solve the problem of filter clogging and will greatly improve the efficiency of producing juice concentrate.

Advantages:

• Filtrate is clear with high transmittance
• Return muddy does not happen for a long time
• No secondary precipitation produced
• No need to add a filter aid
• Purely physical operation at room temperature
• No chemical reaction
• Does not destroy the heat-sensitive substances and affect the fruit flavor easy to use
• Reduce labor intensity and production costs
• Increase productivity
• Small footprint
• Sanitary material

 CIDER JUICE

Ceramic membrane filtration can also be used to produce cider juice, such as apple cider juice.

Process：

 PEAR JUICE

In the fruit juice industry, fruit juice membrane technology is used mainly to clarify the juice by means of  ceramic ultrafiltration and microfiltration and to concentrate it by means of nanofiltration and reverse osmosis.

We look at enzyme immobilization techniques to improve filtration performance and operation methods to quantify fouling.

Membrane fouling is a critical issue and inhibits the broader application of membranes in the fruit production industry. Pectin and its derivatives form a gel-like structure over the membrane surface, thereby reducing the permeate flux. In order to degrade pectin, the raw juice is usually subjected to an enzymatic treatment with pectinase, which hydrolyzes pectin and causes its protein complexes to flocculate. The resulting juice has reduced viscosity and much lower pectin content, which is advantageous in the subsequent filtration processes.

 MUSHROOM JUICE

Mushroom is a common edible fungus in life, rich in protein, 18 kinds of amino acids, vitamins and calcium, iron and other minerals.

However, mushroom's respiration is exuberant after picking. The mushroom quickly becomes browning and changing taste at room temperature and is only for short-term storage. Dried mushrooms are easy to preserve, but the nutritional value is reduced. If you want to store for a long time, you need a higher condition, even in these special circumstances, it is easy to be infected by microorganisms and spoilage, which greatly affects its nutritional value.

After the mushroom is processed into mushroom juice, it not only reduces the storage cost, but also is convenient to eat, and keeps the original nutrients of mushroom. This is the latest type of fruit and vegetable juice drink.

 LUCERNE JUICE

With the development of science and technology, the research on lucerne has been deeply studied, and the nutrition and health function of lucerne have been highly evaluated. Due to rich crude protein cellulose, vitamins, minerals, and complete amino acid composition, it is a worth developing juice in the beverage field.

 VEGETABLE JUICE

Membrane separation processes are widely used in the production of beverage materials and the treatment of water for drinking. The technology can be applied to deacidify, debitter, clarify, concentrate and filter vegetable juices.  It plays an important role in the improvement of product quality, the increase in output and the decrease in production cost. 

Vegetable juices are used due to convenience. The juices are rich in various minerals, vitamins, and other nutrients. To process the juices and their clarification and/or concentration is required. The membranes are being used for these purposes. These processes are preferred over others because of high efficiency and low temperature.

Membranes and their characteristics have been proved for knowing suitability of membranes for vegetable juices. Membrane separation is low-temperature process in which the organoleptic quality of the juice is almost retained.

Ultra filtration method combined with the enzyme treatment method than conventional vegetable production's strength lies in

• Cost saving clarifying agent
• Clarity increases
• Cost saving aid
• Reduce cost centrifuge, filter, reaction tanks
• Save enzyme amount
• Reduce process losses
• Stable and reliable quality
• Continuous operation
• Small footprint
• Simple operation & maintenance

Function: The dynamic flow balance valve keeps the flow constant between 31-600KPa.

Role: Keep the flow through the valve constant.

Theory: When the incoming flow pressure P1 increases, the sleeve of the valve sleeve moves downward, compressing the spring inside the valve bladder, and reducing the flow area of the valve hole at the bottom of the valve bladder, that is, reducing the Kv value of the valve bladder. Thus, although the pressure difference ΔP across the damper is increased, the Kv value is reduced, and the product of the two, that is, the flow rate Q, remains substantially unchanged under the action of the spring.

The pipeline of the constant flow system is installed at the end without stepping.

The pump system is chilled water pump and cooling water pump to prevent the pump from over-flowing when the number of units changes.

A place where a constant flow rate is required, such as a cooling tower.

Water supply pipes or return pipes can be installed.

Selection and precautions

Selection: Only according to the flow selection.

1. The valve pressure working range is greater than the minimum starting pressure difference.
2. It cannot be installed in series with the proportional integral electric control valve.

Constant flow system hydraulic balance scheme

Dynamic differential pressure balancing valve

Theory: The high pressure upstream of the electric regulating valve is guided to the lower side of the control bellows through the pressure guiding tube; the pressure downstream of the electric regulating valve is guided to the upper side of the control bellows through the external pressure guiding tube or the internal pressure guiding hole.

When the pressure on the high pressure side rises, the bellows moves upwards, causing the valve stem and the valve cone to move upward, causing the pressure on the medium pressure side to rise, thereby dynamically maintaining the pressure difference between the medium pressure side and the high pressure side and the spring. The preset force balance ensures the dynamic constant of the pressure difference across the electric control valve. When the pressure on the high pressure side is lowered, the bellows moves downward, and the situation is similar.

Adjust the differential pressure of the spring to adjust the differential pressure setting.

Function: Dynamically keep the pressure difference between the controlled points constant at the set value.

Function:

Ensure dynamic chilled water balancing of the controlled system to prevent dynamic imbalance in the system.

Prevents noise and vibration from being generated by the electric control valve regulating valve.

The regulating valve in the system can be selected with a driver with less driving force to avoid the danger of burning the valve.

Provides good valve authority for the regulating valve, ensures the realization of the linear heat-dissipating controlled system, and ensures the rapid and stable system.

The debugging workload is very small, the installation cycle is accelerated, and debugging can be avoided when the system is changed or expanded.

Conveniently correct the difference between actual and design conditions.

Maximum flow limit function.

Ensure dynamic hydraulic balance of the controlled system.

The dynamic differential pressure balancing valve dynamically maintains the pressure difference ΔP between the controlled points constant at the set value, and the Kv value of the other unoperated electric regulating valve does not change, so the water quantity of the branch is dynamically constant. The amount of water in the branch changes only when the electric regulating valve is actuated, that is, when the Kv value changes.

Prevent electric noise and vibration from the electric control valve.

The adjustment valve uses a driver with a smaller driving force.

The pressure difference between the two ends of the electric regulating valve is constant, and the pressure fluctuation of the system is absorbed by the dynamic differential pressure balancing valve. Therefore, the adjusting valve uses a driver with a smaller driving force.

Provides good valve authority for the regulator valve.

Definition of valve authority:

The pipeline of the fixed and variable flow system is installed at the end without step by step.

The pipeline, branch pipe or riser of the variable flow system is installed without stepping.

The valve of the single-pressure pipe must be installed back to the water, and the valve water supply or return pipe of the double-pressure pipe can be installed.

Selection: The valve body is selected according to the Kv value. The Kv value of the selected valve is greater than the design value. The valve pressure drop is used to calculate the valve Kv value, not the control pressure difference. Select the drive with a controlled differential pressure.

Dynamic differential pressure balance electric control valve

Theory: The essence is that a dynamic differential pressure balancing valve and an electric regulating valve are combined into one. The valve is a double valve cone structure, the upper valve cone is the valve cone of the electric regulating valve, and the lower valve cone is the valve of the dynamic differential pressure balancing valve. Cone, the dynamic differential pressure balancing valve provides a constant pressure difference (0.2Bar or 0.5Bar) before and after the electric valve cone (upper valve cone). The pressure fluctuation of the system is absorbed by the dynamic differential pressure balancing valve, when the electric valve cone ( When the upper valve cone is not actuated, the valve flow capacity kv is constant, and the pressure difference ΔP is constant, so the flow rate Q of the valve is constant; only when the electric valve cone (upper valve cone) acts, the flow through the valve will Changes have occurred, thus achieving a perfect unification of dynamic balance and adjustment functions.

Process: The upper and lower ends of the diaphragm form a balance with the force of the internal spring, ie P1 = P2+P spring.

When the system pressure fluctuates, when P1 increases, the balance is destroyed, and the force below the diaphragm is greater than the upper side, so the diaphragm will move upwards, close the small differential pressure control valve spool, so that P2 increases and reaches equilibrium again. Show.

On the contrary, the differential pressure control valve is opened so that the pressure difference of the regulating valve spool is always constant throughout the operation of the switch, so that the flow rate change through the valve is only one-to-one corresponding to the opening degree of the regulating valve.

The pipeline of the variable flow system is installed at the end without stepping.

The main advantage:

1. The occupied space is small, and the automatic balance of the system is good.
2. One leak point is missing for each group of valves.
3. Easy to install and maintain.

Disadvantages:

1. It is not as flexible as the split solution (dynamic differential pressure balance valve + electric control valve), and the differential pressure of the split solution can be adjusted on site.

Variable flow system hydraulic balance scheme

Solutions to common phenomena of hydraulic imbalance:

1. The system is uneven in temperature and heat. The running energy consumption of the pump is too high → hydraulic calculation, reasonable piping, the same program, static balancing valve. Dynamic differential pressure balancing valve or dynamic flow balancing valve, integral valve.
2. Variable flow system operation is out of regulation. The load is stable, but the room regulating valve moves frequently, causing the room temperature to fluctuate frequently. The system stabilization time is too long → dynamic differential pressure balance valve or integral valve.
3. The regulating valve produces noise and vibration. The regulating valve is not closed, and there is a danger of burning the valve in severe cases. The valve of the regulating valve is too small, the curve of the valve is deformed, and the linear heat-dissipating controlled system becomes a controlled system of the throwing heat. Dynamic differential pressure balancing valve or integral valve.

The purpose of developing high technology is to make it serve human better. Lithium-ion batteries have developed rapidly since 1990 because of their excellent performance and they have been widely used in society. Lithium-ion batteries have rapidly occupied many fields with incomparable advantages over other batteries. As we all know, mobile phones, laptops, small cameras and so on all involve the application and development prospect of lithium battery, and more and more countries use the batteries for military purposes. The application shows that lithium battery is an ideal small green power supply.

The application and development prospect of lithium battery will expand rapidly in the next five years. The application and development prospect of lithium battery is mainly divided into three parts: consumer electronic products, electric vehicles and industrial energy storage. We can find that application focus of lithium batteries is at the stage of development from small batteries market of consumer electronic products to power batteries market of electric vehicles and industrial energy storage. The order is: consumer electronic products market electric vehicles market industrial energy storage market.

In emerging markets such as tablets, electric vehicles (PHEV + EV) and home energy storage, some lithium-ion batteries are the best choice, while others are the first choice. In the market of power grid energy storage which has not yet arisen, the related demonstration operation projects have been carried out at present.

Lithium-ion batteries are gaining ground in the market mainly because of their rapidly declining prices. In terms of performance, lithium-ion batteries are superior to lead-acid batteries, nickel-cadmium batteries, nickel-hydrogen batteries and other major competitors. Through the advantages of performance, lithium-ion batteries gradually expand the market scale. The growth of demand directly leads to the expansion of production capacity and the reduction of manufacturing costs, which in turn stimulates further growth of market demand. In this way, the lithium battery application industry has embarked on a virtuous cycle of development.

Particle size measurement using static light scattering

The particle size distribution as a parameter to specify a powder or dispersion plays a central role in many applications. Examples are construction material (sands, cements), pharmaceutical development, lime stones, ceramics, colored pigments, fertilizers, emulsions and may more. The range of applications is increasing permanently and hence the requirements on the measurement methods regarding size range, measuring time and reproducibility. Particularly the precise and reproducible detection of particles with sizes close to the measuring range limits as well as the simultaneous determination of particle sizes of very small particles (nanometer range) as well as large particles (lower millimeter range) for the characterization of polymodally or very broadly distributed samples provides a challenge. State-of-the-art laser diffraction devices such as the  particle size analyzer for sale solve these tasks by an innovative design of the optical bench for the detection of backscattered light of very small particles and by detecting large particles by an integrated high-speed CCD camera or the combination of static light scattering and Automated Imaging.

Measuring method
In static light scattering laser light (monochromatic, coherent light) interacts with the particles, which have to be characterized in terms of particle size. In dependence of the particles'size, the light waves are scattered by the particles in a characteristic manner: the larger the particles are, the greater is the scattering in forward direction. With particles smaller about 100 nm, the scattering intensity is nearly identical in all directions.

The scattering intensity is determined by stationary detectors depending on the angle (light scattering intensity distribution). State-of-the-art laser diffraction systems such as the Bettersizer S3 Plus guarantee the determination of scattering intensities in a continuous angular range of 0.02 – 165°, i. e. in forward, side and backward direction. This is achieved by means of a so-called double lens design and oblique incidence optical system (DLOIOS technology): Fourier lenses (collective lens) are positioned between the laser and particles as well as between particles and detectors. The particles will interact with the light within a parallel laser beam. This offers the advantage that the scattered light can also be detected at very large angles (in backward scattering direction) and thus even very small particles can be measured precisely. Thanks to DLOIOS technology, the problems of conventional measurement setups can also be avoided. Therefore, neither the suitable lenses for the corresponding particle size measurement range have to be selected prior to the measurement (in comparison to the Fourier optics), nor do measurement inaccuracies result from different particle to detector distances, if not all particles lie in one plane (in comparison to the inverse Fourier optics).

To calculate the particle size distribution from the measured scattering spectra, the theory of either FRAUNHOFER or MIE is applied. The FRAUNHOFER theory is based on the hypothesis of opaque and spherical particles: the scattered pattern corresponds to a thin opaque two-dimensional plate – diffraction only occurs at the edges. Therefore no additional optical input constants of the material are necessary for this calculation. However, this theory is only suitable for mean particle sizes from approx. 5 µm.

In contrast the MIE theory uses the hypothesis of virtually translucent and spherical particles, meaning that the light permeates the matter and is scattered elastically at the atoms of the particle. The knowledge of the complex refractive index of the particles and the liquid as well is necessary. This theory is applicable for particles of all sizes.

The following figure shows an example of a volume-related particle size distribution of a calcium carbonate powder – measured with a Bettersizer S3 Plus.

SOY SAUCE

Soy sauce being eight kinds of amino acid and trace elements is an essential component of human nutrition and health. Due to the application of traditional technique, the long existing problem of secondary sediment of soy sauce which has caused poor appearance, especially finished goods soy sauce on the shelves needs to be solved.

Ceramic sauce membrane separation technology had been extensively used in food and fermentation fields. For example, it is used in the production of apple cider vinegar. This technology used as a substitute for heating, removing thallium and turbidity. It can remove heat-resistant bacteria; keep soy sauce from perishing based on retaining original flavor and save the previous process of diatomite filtration. It also can discolor in order to make from white soy sauce to meet people’s requirements. Heat and oxygen stability of soy sauce after discoloring are been notably improved while containing Fe, Mn and Zn will reduce.

Ceramic membrane is used for clarifying soy sauce. The raw soy sauce is cooked, large particles are removed by sedimentation, and the supernatant filtered through the ceramic membrane. Ceramic membrane filtration does not alter the general composition of soy sauce, but significantly reduces turbidity and count of aerobic microorganisms in the product.

 VINEGAR

The beneficial action of vinegar (white, rosé and red) on the human body has long been known, right since it was used not only as a food but also for medicinal and anti-contamination purposes. In recent years some medical researchers have highlighted the importance of vinegar in the diet, in that it favors the stabilization of certain nutritional components in food.

Vinegar is made from the oxidation of ethanol in wine, cider, fermented fruit juices and/or other liquids containing alcohol.

Filtration is essential to clarify vinegar in view of present production method, micron and submicron suspended particles come into being and polymerize after treating some vinegar with traditional filter way.

Inorganic ceramic membrane filtration technology based on the principle of physical separation display the obvious specialty. Ceramic membranes and their application in filtering and separating china-style vinegar have the advantages over the polymeric membrane and other traditional filters.

Table vinegar passes through the membrane filtration surface; permeate composed of organic acid and matters to form vinegar and ester fragrance in the table vinegar flows through the membrane tangentially, the retentate, micron, and submicron suspended particles, macromolecular protein, and microorganism moves through the membrane. The separation is driven by the pressure difference from one side of the membrane to the other –referred to as transmembrane pressure. A filtration cycle can’t end until the retentate comes up to a certain concentration. Ceramic membrane separation installation is ideally suited to CIP pressure back pulsing in order to keep a stable membrane flux.

Advantages:

• Obtaining a clear filtrate, improving transparency clarity
• The turbidity of permeate is the range of 0.2~0.5NTU
• No discharge of filter aids
• To prevent from the secondary precipitate
• To keep original saline matter, amino acid, total acidity, reducing sugar and other effective ingredients
• To remove bacteria, macromolecular organically matter, suspended solids and some poisonous matters
• To get a bright tint, a sterling fragrance, have no change of non-volatile acid and soluble non-salt solids content
• To substitute the raw vinegar to all the traditional clarification operations (collage, decantation, diatoms filtration, plates, and polymer membranes)
• The chain and technologic time are so considerably shorten
• Low operation cost, compact, maintain conveniently

Basic information

This sustaining valve is opened to prevent the pipeline and equipment from being damaged due to overpressure when the pressure in the water supply pipeline exceeds the set pressure of pressure relief. The valve closes automatically when pressure drops to the set value. 

Features

1. Accurate Pressure Control

2. Fast Opening to Maintain Line Pressure

3. Slow Closing to Prevents Surges

4. Completely Automatic Operation

Principle

Inlet pressure water enters the lower cavity of the pilot valve diaphragm from the guide valve when the pressure in the pipeline exceeds the set pressure of the guide valve to make its pressure increase to open the guide valve, the main valve control room outwards drain under the effect of the inlet pressure water to open the main valve, it starts to discharge pressure. When the pressure in the pipeline drops to the set pressure, the pressure in the lower cavity of the guide valve diaphragm decreases, causing the guide valve closed. This results in increased water pressure from the guide pipe to the pilot valve, then to the main valve control room. The main valve plate closes and begins to hold pressure. 

Installation and Commissioning

The pressure relief(sustaining) valve supports horizontal and vertical installation but should pay attention to the inlet and outlet direction of valve body water when installing. In general, one fire water supply system can only install one pressure relief valve . Within the operating pressure range of the spring specified in the nameplate, the opening pressure can be adjusted by rotating the adjusting screw to change the spring compression amount.

Double regulating valve working principle

Balance valve is a dynamic and static balancing valve under hydraulic conditions. Such as static balance valve, dynamic balance valve.

Valve body material: cast iron, cast steel,

Work pressure is 0.6-4.0 MPA.

The working temperature is - 5 C - 350 C.

Valve caliber DN15-DN300,

Connection mode: flange, internal thread,

Driving mode: manual and electric.

Manufacturing standard: national standard.

Balancing valve is a special function valve. It has good flow characteristics. Besides, it has valve opening index, opening locking device and pressure measuring valve for flow measurement. By using special intelligent instrument, the flow value flowing through the balance valve can be directly displayed by inputting the valve type and opening value according to the measured pressure difference signal. As long as the balance valve with appropriate specifications is installed in each branch and user's entrance and debugged once with the special intelligent instrument, the flow rate of each user can reach the set value.

Static balancing valves are also called balancing valves, manual balancing valves, digital locking balancing valves, double-position regulating valves, etc. It is through changing the clearance between the spool and the seat (opening), to change the flow resistance through the valve in order to achieve the purpose of regulating flow. Its object of action is the resistance of the system, which can distribute the new water in proportion to the design calculation, increase and decrease the branches in proportion at the same time, still meet the flow demand of part of the load under the current climate needs, and play the role of heat balance. Dynamic balancing valves are divided into dynamic flow balancing valves, dynamic differential pressure balancing valves, self-operated differential pressure control valves and so on.

Dynamic flow balance valve is also called self-operated flow control valve, self-operated balance valve, constant flow valve, automatic balance valve, etc. It automatically changes the drag coefficient according to the change of system working condition (differential pressure). In a certain range of pressure difference, the flow through can be effectively controlled to maintain a constant value, that is, when the pressure difference before and after the valve increases, the flow through the valve can be maintained by the action of automatic closing small. On the contrary, when the pressure difference decreases, the valve opens automatically and the flow rate remains constant. However, when the pressure difference is smaller or larger than the normal working range of the valve, it can not provide additional pressure head after all. At this time, the flow rate of the valve to the full open or closed position is still lower or higher than the set flow rate can not be controlled.

Dynamic differential pressure balancing valve, also known as self-operated differential pressure control valve, differential pressure controller, constant voltage variable synchronizer, differential pressure balancing valve, etc. It uses differential pressure to adjust the opening of the valve, and uses the change of pressure drop of the valve core to compensate for the change of pipeline resistance, so as to keep the differential pressure basically unchanged when the working condition changes. Its principle is that in a certain flow range, it can effectively control the constant pressure difference of the controlled system, that is, when the pressure difference of the system increases, it can ensure that the pressure difference of the controlled system increases by automatically closing the valve. When the pressure difference decreases, the valve opens automatically, and the pressure difference remains constant. The self-operated pressure difference control valve has an automatic plug closing state within the control range. The pressure difference between the two ends of the valve exceeds the preset value. The plug opens automatically and adjusts the opening automatically under the action of the pressure sensitive film to keep the pressure difference between the two ends of the valve relatively constant.

The lithium battery advantages are large capacity and high working voltage. The capacity is twice as large as that of the same nickel-cadmium battery, which is more suitable for long-term communication. The voltage of lithium ion is 3.6v, which is three times as high as that of nickel-cadmium and nickel-hydrogen batteries. Charge retention ability is strong, allowing a wide range of operating temperature. After 30 days of storage in open circuit mode at (20 +5) (?) C, the discharge capacity of lithium-ion batteries at room temperature is more than 85% of the rated capacity. Lithium-ion batteries have excellent discharge performance at high and low temperatures, and can work at - 20 ~+55 (?) C. The discharge performance at high temperature is better than that of other batteries.

Long cycle life. Carbon anode is used in lithium-ion batteries. During charging and discharging, the carbon anode will not produce dendritic lithium, which can avoid damage to the inner dendritic lithium short-circuit ears of batteries. After 1200 consecutive charges and discharges, the capacity of the battery is still not less than 60% of the rated value, which is much higher than other types of batteries and has long-term economic use.

It has high safety and can charge and discharge safely and quickly. Compared with metal lithium batteries, lithium-ion batteries have the characteristics of short circuit resistance, overcharge resistance, overdischarge resistance, impact resistance (10 kg weight falling freely from 1 m height), anti-vibration, shooting, needling (penetration), non-fire and non-explosion. Because its anode uses special carbon electrode instead of metal lithium electrode, it allows rapid discharge and can charge and discharge at a charge rate of 1c. So the security performance is greatly improved.

No environmental pollution. Batteries do not contain harmful substances such as cadmium, lead and mercury, which is a clean "green" chemical energy without memory effect. It can be repeatedly charged and discharged at any time. Especially in emergencies, it shows excellent performance.

It has small volume, light weight and high specific energy. Usually, the specific energy of lithium ion batteries can be more than twice that of nickel-cadmium batteries. Compared with the same capacity nickel-cadmium batteries, the volume and weight of lithium ion batteries can be reduced by 30% and 50%, which is conducive to the miniaturization and lightweight of convenient electronic equipment.
