Gate valve is a gate and seat is always in close contact with the valve seal, the principle is the gate with a size of the mouth opening and closing gate makes guichenoti with channel off and consistent action through the gate. The advantage of this valve is that there is no groove in the valve body, the medium will not clog and clog, and it has the full circulation property. It is suitable for use in the pipe of the powder granular medium. The sealing structure of the utility model can be divided into a soft seal and a hard sealing structure. The penetrating flapper valve has precise construction, good manufacturability and compact structure. The valve seat and the gate are close to the movement during the closing and opening process, so that the valve opening and closing force is stable, and it has the characteristics of cutting off the medium. The handwheel can be operated directly by hand wheel to open and close the valve.
