Balance valve

A balance valve is a type of valve with a special function, and the valve itself has nothing special, only the difference in function and field. In some industries, due to the large pressure or flow differences of media (various flowable substances) in various parts of pipelines or containers, valves are installed between corresponding pipelines or containers to adjust the relative balance of pressure on both sides, or to achieve flow balance through diversion methods. This valve is called a balance valve

Balance valve is a valve that plays a dynamic and static balance regulation role under hydraulic conditions. Balance valves can be divided into three types: static balance valves, dynamic balance valves, and pressure independent balance valves. Static balance valve, also known as balance valve, manual balance valve, digital locking balance valve, dual position regulating valve, etc., changes the flow resistance through the valve by changing the gap (opening) between the valve core and valve seat, adjusting the Kv (valve flow capacity) of the valve, in order to achieve the purpose of regulating flow. Its target is the resistance of the system, eliminating the phenomenon of unbalanced resistance in the system, Thus, the new water volume can be evenly distributed according to the design calculation ratio, and each branch can increase or decrease proportionally at the same time. Static balance valves can be used in various applications in the system, such as main pipes, risers, horizontal branches, and ends, with the same effect as same process pipes

Working principle:

The balance valve is a regulating valve with a special function of digital locking. It adopts a DC valve body structure and has excellent equal percentage flow characteristics. It can reasonably distribute flow and effectively solve the problem of uneven cooling and heating at room temperature in heating (air conditioning) systems.

. At the same time, it can accurately adjust the pressure drop and flow rate to achieve the actual effect of balancing the liquid flow in the main pipeline system and saving energy. The valve is equipped with an opening indicator, an opening locking device, and a pressure measuring small valve for flow measurement. As long as a balance valve of appropriate specifications is installed in each branch and user inlet, and a one-on-one intelligent instrument is used for one-time debugging and locking, the total water volume of the system is controlled within a reasonable range, thus overcoming the problem of; Large flow rate, small temperature difference; The unreasonable phenomenon of. The balance valve can be installed on both the water supply pipe and the return pipe. Generally, it should be installed on the return pipe, especially for high-temperature circuits. For easy debugging, it should be installed on the return pipe. The supply (return) pipe with the balance valve installed does not need to be equipped with a shut-off valve. Install a balance valve in the pipeline system and adjust it to change the resistance ratio of the system's pipeline characteristics, achieving consistency with the design requirements. After the system debugging is qualified, there is no static hydraulic imbalance problem. If a system that has been debugged successfully is in partial load operation, the flow rate of each branch pipeline regulated by the balance valve will automatically decrease year-on-year when the total flow rate decreases, but the flow rate ratio set by each branch pipeline remains unchanged
