Multifunctional pump control valve structural features multifunctional pump control valve from the main valve and the regulator valve and take over the system components, valve using DC-type body, the main control room for the diaphragm valve or piston dual control room structure, control room adds an increase of the main valve control function than the general hydraulic control valve, the realization of the export pump slowly open, full, slow closing, closing and other multi-functional control to achieve a valve, a regulator of the pump outlet Multi-function control. The system uses this product to take over control valve opening degree, by setting the control valve can be easily controlled to achieve the required parameters, such as the opening speed of the main valve, slow closing speed and so on. Works when the pump after starting play, pressure acting on the main valve disc and the control room below the lower chamber, the pressure of the main valve is opened, the upper chamber of the water control room control valve B slowly discharged through the outlet end, the main valve relief slow to open. Regulating valve opening degree setting landlord obtained an appropriate valve opening speed. When the pump stops working, the inlet end of the water pressure decreased rapidly under its own weight, the spring pressure to quickly turn off most of the opening, to prevent the backflow of water remaining in the opening of the joint action by the upper chamber pressure control chamber and a lower chamber pressure By slowly closing, closing speed slows the formation of a buffer to prevent pressure surge. Setting valve A, B, and the opening of the opening of the appropriate valve opening and closing faster than available. Function and use of the valve is installed in the pump outlet end, the order of realization slowly open, full, fast closing, slow closing functions. This product pump discharge piping water supply system for high-rise buildings and other water supply systems to prevent and weaken when opening and closing the pipeline pump water hammer water hammer, water pumps to prevent water backflow protection, maintenance, pipeline safety.
