working principle

H142X hydraulic water level control valve is a hydraulic control valve that automatically controls the liquid level of the water tank and water tower. When the water level drops beyond the preset value, the float valve opens, the pressure in the upper chamber of the piston decreases, and the pressure difference is formed above and below the piston. Under this pressure difference, the valve flap opens to perform the water supply operation; when the water level rises to the preset height, the float valve When closed, the pressure on the upper chamber of the piston is increased, causing the flap to close and stop the water supply. This reciprocating automatic control of the liquid level at the set height enables automatic water supply.

haracteristics

It has four functions: stop valve, check valve, electric valve and water hammer canceller. It is especially suitable for supporting dynamic control system. It does not need electrical controller and external power, and automatically opens and closes according to the routine. It has three functions of preventing and eliminating water hammer, which can effectively improve system safety. reliability. Meet the requirements of system engineering equipment automation control.
