Description

Technical Field

[0002] The pressure regulating valve is also called self-operated balancing valve, flow control valve, flow controller, dynamic balancing valve, and flow balancing valve. It is an intuitive and simple flow regulation control device. The flow regulating valve used in the pipeline network can directly set the flow according to the design. The valve can automatically eliminate the flow deviation caused by the residual pressure head and pressure fluctuation of the pipeline under the action of water. No matter how the system pressure changes, the set flow is maintained unchanged. These functions of the valve enable the pipeline network flow regulation to be completed at one time, turning the network adjustment work into a simple flow distribution, and effectively solving the hydraulic imbalance of the pipeline network.
