1.6 Mpa Flange End 700X Water Pump Control Valve Water Conservancy Valve

Introduction

700X pump control valve is a check valve installed at the pump outlet of high-rise buildings and other water supply systems to prevent medium backflow. When the water pump is about to stop supplying water. Slowly close about 90% of the valve first to prevent water hammer or water hammer sound caused by sudden pump stop; When the water pump is completely stopped, the valve is completely closed to prevent the backflow of the pumped water and effectively protect the water pump from reverse rotation caused by the impact of backflow. The product is an essential protection device for the outlet of the water pump. The valve is of streamlined design. Accurate opening and closing can be realized through the guidance and control of solenoid valve. The utility model has the advantages of safe and reliable use, effective prevention of water hammer and water hammer sound, long service life and convenient installation and maintenance.

Usage

The water pump control valve can control the water pump s non-return valve. Before the water pump stops working the intake pressure close90%ofmain valve at first, then thethe water pump will automatically syop, and the reserved 10% will be closed by the backwate, which can avoid occurring thewater hammering t is applicable to directly supply water by water pump in plante, mines, enterprises and the high buildings and the water for living pipelinet systems

working principle

When the working valve of the water pump supplies water to the downstream, the solenoid pilot valve is fully opened, the needle valve is adjusted to an appropriate opening, and the upstream water enters the main valve control room through the needle valve and one-way valve and flows out through the solenoid pilot valve. At this time, the pressure in the main valve control room keeps the main valve at an appropriate opening to keep the downstream normal water.

When the water pump stops working, the solenoid pilot valve is closed first, the main valve control room stops drainage, the pressure in the control room rises, and the main valve starts to close. When it is closed to 90%, the upper travel switch of the main valve outputs the pump stop signal and the water pump stops running. At this time, the downstream return water enters the main valve control room through the check valve, the pressure in the control room rises and the main valve is closed.
