Piston multi-function pump control valve structure is what?

Piston-type multi-function Pump Control Valve for high-rise building water supply system and other water supply system of the pump outlet pipe to prevent and reduce the water pump when the pump opening and closing of the water hammer water hammer to prevent water back to protect the pump maintenance Pipeline safety. Now through the graphic way to understand the structure of the lower piston multi-function pump control valve. Piston multi-function pump control valve structure Piston multi-function pump control valve Structural features Multi-function pump control valve is installed in the large-diameter water supply pipe network pump outlet to prevent the media backwater hammer and water hammer phenomenon of smart VALVES . The valve combines the functions of electric valve, check valve and water hammer eliminator, which can effectively improve the safety and reliability of the water supply system for the fire water and domestic water in the living quarters. Multifunctional pump control valve consists of main valve and control valve and take over the system, the valve body with DC valve body, the main valve control room for the diaphragm or piston double control room structure, the control room than the general increase of the HYDRAULIC CONTROL VALVE A, an increase of the main valve control functions, to achieve a slow opening of the pump outlet, fully open, slow closure, cut-off and other multi-function control, to achieve a valve, a control of the pump outlet multi-function control. The product takes over the control system using the valve control, by setting the opening of the control valve can be easily achieved all the necessary control parameters, such as the opening of the main valve speed, slow closing speed and so on.
