| description | The utility model provides an ultrahigh-pressure large-drift-diameter plane shearing sealing valve, which belongs to the technical field of sealing valves and comprises a valve body, a lower piston, a bottom plate, a valve plate pull rod, two valve seat sleeve joints, an upper piston, an upper cover and a shearing sealing structure. The mirror face is opened and closed up and down in a sliding mode between the sealing valve plate and the sealing valve seat, impurities attached to the valve plate are pushed and scraped out during opening and closing each time, it is guaranteed that the sealing mirror face is clean, high in sealing tightness and free of external leakage, the failure rate is reduced, the service life of the valve is prolonged, the sealing valve is controlled hydraulically, the automation degree is high, and operation is convenient. The shearing sealing valve can be accurately fed back and controlled to be opened and closed through the pressure sensor, the pressure testing precision is greatly im |
