Working principle: Hydraulic control valve for automatic control of water tank and water tower level. When the water level drops more than the preset value, the float ball valve opens, the pressure of the upper chamber of the piston decreases, and the pressure difference between the upper and lower piston is formed, and the brake valve opens the water supply operation under this pressure difference. When the water level rises to the preset height, the float ball valve is closed, and the increasing pressure in the chamber above the piston causes the valve flap to close and stop the water supply.
