Description

Water leakage protection valve for heating Technical Field The utility model relates to the technical field of valves, in particular to a water leakage protection valve. Background In the heating pipeline, water leakage is one of frequent accidents, and certain property loss is often caused, and the existing heating pipeline, especially the pipeline of the water separator of the water inlet pipeline, is usually provided with a ball valve which can be manually closed once water is leaked. However, water leakage is not known, and occurs suddenly, and if the situation is not found in time, a large amount of water leakage is submerged in a room, and even a plurality of layers below the building are damaged. Therefore, there is an urgent need for a valve capable of automatically closing the water supply of a pipe when water leaks. Disclosure of utility model The utility model aims to solve the technical problems, and provides a heating water leakage protection valve which comprises a valve body, wherein a gland is arranged at the upper end of the valve body, a frame-shaped sealing ring is arranged between the gland and the valve body, the gland is connected with the valve body through a fixing screw, a water inlet and a water outlet are respectively arranged at two ends of the valve body, a valve sealing wall is arranged at the middle position of the lower end of the valve body, a water flow through hole is arranged in the middle of the valve sealing wall, a groove is arranged at one side of the water flow through hole, which faces the water inlet, an O-shaped sealing ring is arranged in the groove, a shaft hole is arranged at the upper end of the valve sealing wall, a rotating shaft is arranged in the shaft hole, the rotating shaft is fixedly connected with the root of a baffle, and the end part of the baffle corresponds to the O-shaped sealing ring when rotating; the front end of the rotating shaft penetrates through the shaft hole and corresponds to a blind hole in the rear side wall of the valve body, the rear end of the rotating shaft penetrates through a through hole in the front side wall of the valve body, a rotating seal ring is arranged between the through hole in the front side wall of the valve body and the rotating shaft, the front side wall of the valve body is further provided with a rotating resistance adjusting structure, the rotating resistance adjusting structure comprises an adjusting O-shaped seal ring embedded into a groove in the front side wall of the valve body, the axial front end of the adjusting O-shaped seal ring is abutted to the front side wall of the valve body, the axial rear end of the adjusting O-shaped seal ring is abutted to a pressing block, the radial inner side of the adjusting O-shaped seal ring is abutted to the rotating shaft, the pressing block is fixed to an adjusting pressing plate, and the adjusting pressing plate is fixed to the front side wall of the valve body through a screw. The end of the baffle is provided with a bending part, and the lower end of the valve closing wall is provided with a buckling groove with a corresponding shape. The gland is provided with a pressure gauge interface. The valve body is square. The rear end of the rotating shaft is provided with a handle.
