The vertical cylindrical end of the spring 1-3 penetrates through the water inlet 1-4 of the control mechanism of the sealing disc 1-2.

The utility model discloses a theory of operation: firstly, an original state: the water inlet of the control valve is perpendicular to the horizontal plane and is arranged in the water tank. When the water tank is empty or is not full of water, the floating ball is in a downward state. The lever pressing plate rotates around the rotating shaft under the action of self gravity, one end of the lever pressing plate also leans against the upper plane of the floating ball downwards, and a plug on the lever pressing plate is separated from a pressure relief opening of the control mechanism. At this time, the water inlet, the control mechanism pressure relief port and the water tank are communicated. The sealing element and the sealing disc close the communication port of the water inlet and the water outlet under the action of the elastic force of the spring. This state is the original state.

II, water flowing state: when water enters the control valve from the water inlet, the water inlet of the control mechanism, the pressure relief port of the control mechanism and the water tank are communicated in the original state. Therefore, water can enter the valve body from the water inlet of the control mechanism, and simultaneously, the water flows out of the pressure relief opening of the control mechanism to the water tank. At this time, the pressure in the ball float valve body is far lower than that of the water inlet, so that the sealing element and the sealing disc downwards compress the spring under the pushing action of the pressure of water in the water inlet until the sealing disc abuts against the wall of the middle cover and stops moving downwards. At this time, the water inlet is communicated with the water outlet, and water normally flows out of the water outlet.

Thirdly, water shut-off state: when the water in the water pool rises to the position of the floating ball of the control valve, the water passes through the water inlet hole of the cover and enters the valve to support the floating ball to move upwards. Meanwhile, the movement of the floating ball drives the lever pressing plate to rotate upwards around the self axis. When the water rises to the level that the choke plug on the lever pressing plate can completely block the pressure relief opening of the control mechanism. At the moment, the pressure in the valve body is equal to the pressure of the water inlet, but the pressure of the water outlet is far lower than the pressure in the valve body, at the moment, the sealing element and the sealing disc move upwards under the pushing action of the pressure in the valve body until the sealing element completely blocks the communication port between the water inlet and the water outlet, water cannot normally flow out of the water outlet, and the control valve is in a water closing state.
