07.Operating principle
The slow closing check valve is composed of the main valve and control pipeline of the hydraulic control valve and is installed at the outlet of the water pump of the building water supply system.When the pump is open, the water flow gives upward thrust to the disc of the main valve, and the upper chamber of the main valve drains out to open the main valve. The opening time of the main valve can be controlled by adjusting the opening size of the ball valve on the control pipe.When the pump is closed, the upward thrust at the disc disappears, and the water flows back to fill the cavity of the main valve, so that the main valve is closed. By adjusting the opening of the ball valve on the control pipe, the closing time of the main valve can be controlled.
