The main principle of balance valve

Balance valve is a regulating valve with a special digital locking function. It adopts a DC valve body structure and has better equal percentage flow characteristics. It can reasonably distribute flow and effectively solve the problem of uneven room temperature cooling and heating in heating (air conditioning) systems. At the same time, it can accurately adjust the pressure drop and flow rate to improve the liquid flow state in the pipeline system, achieve liquid balance in the pipeline network, and save 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 dedicated intelligent instrument is used for one-time debugging and locking, the total water volume of the system is controlled within a reasonable range, thereby overcoming the unreasonable phenomenon of "large flow, small temperature difference". 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.
