The advantage of the penetration flapper valve is that the valve body has no groove, the medium will not clog and clog, and 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.
Suitable medium: coal, slag, food, papermaking, medicine, chemical industry pipeline used in mining power plant, medium cement slurry, powder, gold ore, slag, coal, pulp, wood pulp, tailings, fiber, dust, chemicals, sewage settling ponds, asphalt, etc. the outlet connect or disconnect the line the.
