Abstract

The utility model relates to the technical field of stop valve, concretely is the drain stop valve for high parameter power station, including the valve body, its top end is fixedly installed with the valve cover through the bolt, and the middle part of valve cover and valve body is provided with the opening and closing mechanism, the valve seat is fixedly connected in the middle part of the inside of valve body, and the cut -off mechanism is provided between the valve seat and opening and closing mechanism. The utility model discloses the cooperation of pressure self -compensation sealing structure, when medium pressure rises, greater radial compression deformation is produced to O ring under the pressure effect, and sealing specific pressure is along with system pressure automatic increase, ensures that can maintain reliable sealing under different working conditions.
