JD745X Multifunctional Pump Control Valve

Brief Introduction

JD745X multi-function pump control valve isinstalled in high-rise building water supply systems and other water supplysystem pump outlet, to prevent the medium backflow, water hammer. The valve combines electric valve, check valve and water hammereliminator three functions, can effectively improve water supply systemsecurity and reliability. And integrates slow opening, fast closing, slowclosure of water hammer eliminating technical principles, to prevent the pump openingwater hammer and pump stop water hammer. Just operate the pump motor open andclose button, the valve can automatically open and close in accordance withpump operating procedures, the flow is large, pressure loss is small.

Working Principle

When the pump starts, the water pressure workson the main valve disc lower part and control chamber lower part, the pressure opensthe main valve, the water of upper control room flows slowly to the outlet throughthe adjusting valve, the main valve opens slowly. Set the opening of thecontrol valve to get the appropriate main valve opening speed. When the pumpstops working, the water pressure at the inlet drops rapidly and closes most ofthe opening rapidly under the action of self-weight and spring pressure toprevent the backflow of water. The remaining opening is controlled by thepressure in the upper chamber of the control room and the water pressure in thelower chamber. Closing speed is slow down to form a buffer to prevent thepressure surge.
