Abstract

The utility model discloses a water inlet valve, which comprises a valve and a valve cover covered on the valve body, wherein the inside of the valve is provided with a water sealing ring and the water sealing ring is provided with a valve needle hole. The utility model is characterized in that the inside of the valve needle hole is provided with a valve needle which can correspondingly rotate in the hole. When a water inlet valve is under a water admission state, the top point of the valve needle is stressed by a valve cover. A certain gap remains between the water sealing ring and the valve needle, and a spiral slope of the valve needle do the self-rotation at high speed in virtue of the water admission action and moves up and down. When dirt and silt contained in water pass through the small hole of the valve needle, the dirt and silt can be easily discharged from the small hole to avoid the ineffectiveness of the water inlet valve. When the water inlet valve is under the water sealing state, the water inlet end of the valve needle is appressed with the water sealing ring in virtue of water pressure. Thus the dirt and the silt can not enter and precipitate in valve needle hole to block the plug valve needle hole. The utility model has the advantages of simple structure, difficult ineffectiveness and long service life.
