Multi functional water pump control valve

The multifunctional water pump control valve is mainly composed of a main valve, a regulating valve, and a receiving system. The valve body adopts a DC valve body, and the main valve control chamber is a dual control chamber structure of diaphragm or piston. The control chamber is added to the general hydraulic control valve, which increases the control function of the main valve and realizes the multifunctional control of slow opening, full opening, slow closing, and cutoff of the water pump outlet. It realizes the multifunctional control of the water pump outlet with one valve and one adjustment. The multifunctional water pump control valve produced by Shanghai Meiyan Yi Pump Valve has the following working characteristics: it has good water hammer prevention effect, integrates technologies such as slow opening, check speed closing, and slow closing to eliminate water hammer, and prevents damage to the water supply pipeline and water pump caused by water hammer when the pump is turned on and stopped due to backflow; Easy to operate, no need to equip the valve with a separate electrical control system. The valve automatically and sequentially completes the control function with the opening and stopping of the water pump. Suitable control parameters can be obtained by setting the opening of the regulating valve. The main working principle of the multifunctional water pump control valve is that the opening of the main valve plate is determined by the impact force of the water flow in the pipeline. When the flow rate is high, the opening degree of the main valve plate is large, and when the flow rate decreases, the opening degree of the valve plate is small; When the flow rate approaches zero, the main valve plate closes. The entire process is consistent with the two-stage closure principle of eliminating water hammer, so the effect of eliminating water hammer is very good.
