Abstract

The utility model relates to a water control gas switch, which is provided with a left disk body, a right disk body and a rubber film which is clamped and fixed between the left disk body and the right disk body. The rubber film separates the closed space thereof into a left chamber and a right chamber. The left chamber and the right chamber are separately connected with a water inlet and a water outlet. When the water source is opened, the water flows in a conduit pipe, the water of the right chamber is sucked to immit the left chamber, and the water pressure of the left chamber is higher than the water pressure of the right chamber to move the rubber film to open the gas valve. When the water source is closed, the water stops flowing, and the water pressure of the left and right chambers is higher than the atmospheric pressure at the left side of the gas valve to shift a centre rod and the gas valve to the left. So the water pressure suddenly increases and the centre rod and the gas valve have the tendency to move left to close the gas tightly. The leaking of the gas is avoided.
