The utility model relates to a marine riser filling valve non -pressure hydraulic control system control valve that stretches out and draws back, which comprises the following components: a valve body, a piston, the end cover, pressure sensor, the oil storage storehouse, a controller, oil storage storehouse and controller are located the valve body surface, the piston is located inside the valve body, a boss is all set for to valve body internal surface and piston surface, and valve body location boss constitutes the oil pressure chamber with piston location boss, valve body lateral wall and oil pressure chamber correspond position department in addition at least two lead the oilhole, pressure sensor install respectively on leading the oilhole with the oil storage storehouse in, the valve body lateral wall corresponds position department two supplementary pressure boost oilholes in addition with the oil pressure chamber, pressure sensor and solenoid electric valve all are connected with controller for electric. This novel can be when reasons such as the hydraulic pressure oil circuit hinders for some reason lose pressure suddenly, for the pneumatic cylinder provides emergent pressure output, provide emergent motion power for the pneumatic cylinder to ensure that the marine riser filling valve hatch door can open and shut smoothly under emergency, ensure equipment operation safety.
