Connection, the periphery of barrier film 3 is arranged on cylinder body 1 by gland, and the center of barrier film 3 is bolted to connection with the one end of guide rod 4, guide rod
4 other ends are located in the chamber of fluid power pipe 2.Mounting hole is provided with the center of cylinder body 1, the guide bar support 7 is arranged in cylinder body mounting hole
And stretch into fluid power pipe 2.Pilot hole is provided with the center of guide bar support 7, guide rod 4 enters in fluid power pipe 2 through pilot hole.In guide rod
Support 7 is provided with oil drain passage 8, and oil drain passage 8 is connected with oil extraction check valve 5.Repairing is provided with by bolt on fluid power pipe 2
Valve body 9, one end of repairing valve body 9 is radially into fluid power pipe 2, and the other end of repairing valve body 9 is located at outside fluid power pipe 2 and is provided with the end
The repairing check valve 6, is provided with the repairing passage 10 connected with repairing check valve 6 in repairing valve body 9.In repairing valve body 9
Be provided with repairing guiding valve 11 in that end in fluid power pipe, repairing guiding valve 11 be used for repairing passage 10 and the inner space of fluid power pipe 2 or
Person disconnects, and controls the valve rod 12 of repairing guiding valve break-make to be located along the same line with guide rod 4 on repairing guiding valve 11, when guide rod 4 is to valve
When the direction of bar 12 is moved, valve rod 12 can be promoted to move together.This structure is controlled the motion of valve rod by guide rod, when guide rod promotes valve rod
When moving to certain position, repairing guiding valve connects repairing passage with fluid power tube cavity, and now whole repairing path communicates, Ke Yijin
Row repairing.Otherwise repairing path disconnects, it is impossible to repairing.
Referring to Fig. 3, except valve rod 12, the repairing guiding valve 11 also includes valve seat 13 and stage clip 14, and valve seat 13 is fixedly mounted
On repairing valve body 9, valve seat 13 is provided with the valve rod hole and repairing hole 15 for being mutually perpendicular to insertion, repairing hole 15 and repairing passage 10
Communicate.Valve rod 12 is arranged in valve rod hole and disconnects repairing hole 15, and valve rod 12 is provided with the repairing hole 15 that can be will be switched off and connects
Intercommunicating pore 16.The two ends of valve rod 12 are stretched out from valve rod hole, and valve rod 12 is provided with press spring base 17 near guide rod, and stage clip 14 is enclosed within valve
On bar 12 and be located between press spring base 17 and valve seat 13, stage clip 14 effect under, valve rod 12 all the time have moved to the direction of guide rod 4
