The multi-function water pump control valve is composed of a main valve, a regulating valve and a connecting pipe system. The valve body adopts a direct flow valve body. The main valve control room is a diaphragm or piston type dual control room structure. The control room is one more than the general hydraulic control valve, and the control function of the main valve is added. It realizes the multi-function control of the slow opening, full opening, slow closing, and cut-off of the water pump outlet, and realizes a valve Multi function control of primary regulation on water pump outlet. This product is used on the pump outlet pipeline of the water supply system of high-rise buildings and other water supply systems to prevent and weaken the water hammer and water hammer of the pipeline when the pump is opened and closed, prevent water backflow, protect the pump, and maintain the pipeline safety. In order to realize the automation of water pump operation, simplify management, reduce labor, and improve reliability, people have replaced manual valves with hydraulic valves and electric valves, and made a number of technical improvements to individual valves. New types of valves have emerged, such as slow opening and slow closing check valves, slow opening and closing hydraulic valves, automatic slow closing gate valves, and dual speed self closing valves.
