- Prevent the effect of water hammer, eliminate the technical integration of water hammer, such as slow opening, stopping speed closing, slow closing and soon, so as to prevent the damage of water supply pipeline and pump caused by open pump, non-hammer and back flow of pump, and the damage of water hammer to water supply pipeline and pump.
- The operation is convenient, and the other power distribution control system of the valve is not required, and the valve can automatically and sequentially complete the control function with the opening and stopping of the water pump.A suitable control parameter can be obtained by setting the opening of the regulating valve.
- The valve body adopts full channel, direct flow, streamline design. The hydraulic loss is small and the energy saving effect is good.
The working principle of the multi functional water pump control valve is as follows: after the water pump is started, the water pressure acts on the lower part of the valve disc of the main valve and the lower cavity of the control chamber, the pressure causes the main valve to open, the water in the upper cavity of the control chamber is slowly discharged to the outlet end through the regulating valve b, and the main valve is slowly opened. Setting the opening of the regulating valve to obtain the proper opening speed of the main valve. when the water pump stops working, the water pressure of the inlet end is rapidly reduced, a large part of the opening degree is rapidly closed under the action of the self-weight and the spring pressure, the remaining opening degree of the reverse flow of water is slowly closed under the combined action of the water pressure of the upper cavity of the control room and the water pressure of the lower cavity, and the closing speed is reduced to form a buffer, Prevent pressure surges
The product is used on the water pump outlet pipe of high-rise building water supply system and other water supply system to prevent and reduce the water hammer water hammer of the pipeline when the water pump is on and off, to prevent the water from flowing back to the water pump and to maintain the pipeline safety.
