Background technique

Flow regulating valve, also known as self-operated flow control valve, flow balancing valve, static balancing valve, is an intuitive and simple flow regulating control device. The flow regulating valve used in the pipeline network can directly set the flow according to the design. The valve can be used in Under the action of water, the residual pressure head of the pipeline and the flow deviation caused by pressure fluctuations are automatically eliminated, and the set flow rate remains unchanged no matter how the system pressure changes. These functions of the valve make the flow adjustment of the pipeline network complete at one time, and the network adjustment work becomes easier. For simple flow distribution, effectively solve the hydraulic imbalance of the pipe network.

1. During the use of the existing water flow regulating valve, since the setting of the maximum water output is adjusted from the water inlet, and the adjustment effect can only be seen when the joint is installed on the water pipe, repeated adjustments are required to achieve satisfaction When the water output is high, the joint must be removed and reinstalled repeatedly, which is not convenient to adjust.

2. During the use of the existing water flow regulating valve, the internal friction between the valve disc and the valve body is relatively serious. After a long time, the valve disc will wear and become smaller, so that there will be a gap between the valve disc and the porous water flow valve plate, resulting in There is water flow through, resulting in waste of resources, so it is necessary to improve the existing water flow regulating valve.
