Zusammenfassung: | The invention belongs to the technical field of petroleum drilling and production, and discloses a mechanical-electrical-hydraulic integrated test valve which comprises an upper connector and a ball valve outer cylinder which are connected with each other, a ball cage is arranged in the ball valve outer cylinder, a ball valve assembly is movably connected in the ball cage, one end of the ball cage is connected with a ball seat short section through a retaining screw, and the other end of the ball cage is connected with an executing mechanism. The opening and closing movement of the ball valve assembly is controlled through the executing mechanism; the actuating mechanism is connected with a power mechanism which provides power for the actuating mechanism to drive the ball valve assembly to open and close, and the end, away from the actuating mechanism, of the power mechanism is connected with a lower connector. Opening/closing of the flow channel is achieved through cooperation of the electric appliance eleme |
