description The utility model discloses a valve sealing performance detection device which comprises a detector body, a controller, an indicating lamp, a lower air outlet channel, an upper air outlet channel and a fixing device. The fixing device is arranged, the motor is started, the double-tooth lead screw is driven to transmit, then the two sets of supporting frames move oppositely, the extrusion plate and the friction plate are driven to clamp and support a valve, the supporting device is used for auxiliary supporting, the supporting force on the valve is enhanced, and the valve can be fixed through clamping and fixing of the extrusion plate and supporting of the supporting device. When a supporting frame moves inwards, a movable plate is driven to slide in a supporting plate, a limiting hole in the bottom end of the movable plate is made to gradually move upwards, when a limiting column makes contact with the limiting hole, the limiting column is not squeezed and is rapidly embedded into the limiting hole under the
