Abstract

The utility model provides a novel water stopping device for a water inlet valve. The novel water stopping device comprises a branch plate provided with a water inlet and a plurality of water outlets. The branch plate is sleeved with a film pressing valve core device. The film pressing valve core device comprises a valve cover and a water stopping rubber mat which is fixed on the bottom of an inner cavity of the valve cover and used for sealing the water inlet. A pressure releasing hole in the top of the valve cover and a pressurizing groove in the middle of the water stopping rubber mat are communicated with the inner cavity and the water inlet constantly. The novel water stopping device further comprises a buoyant force assembly opening and closing the pressure releasing hole. Pressure of the inner cavity is released so that the water stopping rubber mat shrinks to open the water inlet. The pressure of the inner cavity is increased so that the water stopping rubber mat expands to close the water inlet. The water stopping rubber mat is provided with a ring-shaped extension concave film protruding towards the exterior of the inner cavity. The ring-shaped groove in the branch plate is used for elastically locating the extension concave film in an expanding mode. The water stopping rubber mat is sensitive to internal and external pressure difference of the inner cavity, the speed of actuating the rubber mat through the internal and external pressure difference is higher, and the effect of regulating water pressure automatically is obvious. Moreover, when the pressure of the inner cavity is increased, stress on the extension concave film is increased greatly, so that the extension concave film can be expanded and matched with the ring-shaped groove in a locating and sealing mode, and sealing and water stopping capacities of the extension concave film on the water inlet are improved.
