What kind of valve is the multifunctional water pump control valve? In fact, the multifunctional water pump control valve is composed of a main valve, a regulating valve and a pipe connection system. The valve body adopts a direct-flow valve body, and the main valve control room is a diaphragm type or a piston type. Double control room structure, the control room has one more than the general hydraulic control valve, which increases the control function of the main valve, and realizes the slow opening, full opening, slow closing, cut-off and other multi-function control of the water pump outlet, and the realization of a valve , One-time adjustment of the multi-function control of the pump outlet. This product is used in the pump outlet pipelines of high-rise building water supply systems 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. 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 single valves. Slow-opening, slow-closing check valves and slow-acting have appeared. Open and close hydraulic valves, automatic slow-closing gate valves, two-speed self-closing valves and other new types of valves.

The working principle of multifunctional water pump control valve
When the multi-function water pump control valve working valve supplies water downstream, the solenoid pilot valve is fully opened and the needle valve is adjusted to an appropriate opening. The upstream water enters the main valve control room through the needle valve and the one-way valve, and flows out through the solenoid pilot valve. The pressure in the main valve control room keeps the main valve at a proper opening and maintains normal water supply downstream.

When the multifunctional water pump control valve stops working, the solenoid pilot valve is closed first, the main valve control room stops draining, the pressure in the control room rises, and the main valve starts to close. When it is closed to 90, the upper stroke switch of the main valve will output a pump stop signal, and the water pump will stop running. At this time, the downstream backwater enters the main valve control room through the one-way valve, the pressure in the control room rises, and the main valve is closed.
