[0021] Working principle: When using this efficient valve sealing inspection device, first place the valve body 16 between the two docking rings 3, then the single chip microcomputer controls the electric push rod 9 to work and push the transmission arm 12 to move, driving the two docking rings 3 to approach each other, so that the positioning rod 15 is inserted into the connection hole of the flange on the valve body 16, and then the valve body 16 is clamped.
