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 to introduce the working principle and work characteristics of the piston-type multi-function pump control valve. Piston multi-function pump control valve First, the multi-function piston pump control valve works When the pump starts, the pressure acting on the valve below the main valve and control room under the cavity, the pressure to open the main valve, the control room on the chamber Water slowly through the control valve B to the exit side, the main valve slowly open. Setting the opening of the control valve results in a proper main valve opening speed. When the pump stops working, the water pressure at the inlet decreases rapidly, most of the opening is quickly closed under dead weight and spring pressure to prevent the water from flowing back. The remaining opening degree is controlled by the combination of the water pressure in the upper chamber and the water pressure in the lower chamber Slowly shut down, slow down the closure of the formation of a buffer to prevent the pressure surge. Set the control valve A, B opening and opening ratio can be a suitable valve opening and closing speed. Second, the piston-type multi-function control valve pump features 1, to prevent the water hammer effect is good, will slow open, check back speed closed, slow closing, etc. to eliminate the technical integration of water hammer to prevent the pump not hammer and stop the pump back and water Hammer on the water supply pipe and pump damage. 2, easy to operate, no need to reprovision the valve with electronic control system, the valve with the pump to open and stop automatically and in order to complete the control function. By setting the valve opening degree can get the appropriate control parameters. 3, the valve body with a full channel, DC, streamlined design. Small hydraulic loss, energy-saving effect.

The liquid inlet/outlet adopts a ceramic hard seal structure, the liquid is in contact with the ceramic throughout the entire process, and does not touch the stainless steel jacket. The ceramic parts of the liquid inlet/outlet can be disassembled for cleaning and disinfection like the ceramic plunger rod and the ceramic reversing rod, which completely solves the problem of cleaning the dead angle between the steel jacket and the ceramic.
