working principle

When the pipeline feeds water from the inlet end, since the needle valve, the ball valve and the float valve are normally open, the water enters the pool through the micro filter, the needle valve, the control chamber, the ball valve, and the float ball valve, and the control chamber does not form pressure, the main The valve is opened and the water tower (pool) is supplied with water.

When the water level of the water tower (pool) rises to the set height, the float floats to close the float valve, and the water pressure in the control room rises, pushing the main valve to close, and the water supply stops. When the water surface drops, the float valve is re-opened, the water pressure in the control room drops, and the main valve is opened again to continue the water supply, maintaining the set height of the liquid level.
