Balancing valve function and working principle

Balance valve is a kind of equipment used to control the flow and pressure of the pipeline, by automatically adjusting the opening of the valve to maintain the balance of system pressure, prevent overload, energy saving and other purposes.

Balance valve is a self-regulating valve, which has resistance characteristics, and can stably handle the temperature, pressure, flow and other parameters of water flow, air flow or steam and other media, and is widely used in heating, cooling, and industrial automation control fields.

The main function of the balance valve is to install the same number of balance valves on the branch pipe, and adjust the opening of the valve to achieve the same flow of the branch, so as to avoid the problem of insufficient flow of other branches due to the large flow of some branches, circulating pump operation overload and other problems, while realizing the system energy efficiency optimization and operating cost reduction.

The working principle of the balance valve is to change the cross-sectional area of the valve, so that the area through the medium changes, so as to control the flow of the medium. When the medium passes through the balance valve, the increase in the flow rate of the fluid and the reduction of the pipe that leads to the reduction of the resistance will reduce the pressure of the fluid in the channel, and the spring tension will gradually increase, the valve opening will gradually decrease, and the flow rate will be offset.

Balance valve is a kind of equipment commonly used in fluid system, its main role is to adjust the flow of fluid by changing the opening of the throttle valve to achieve constant flow, so that the fluid system runs more stable and reliable. Its working principle is to use the balance principle of air pressure, hydraulic pressure and other forces to adjust the size of the flow in order to achieve the purpose of controlling the fluid.
