Particularly, described extenal fixation ring comprises rotating shaft, two semi-rings, connecting sheet and connecting bolts, the first end of two described semi-rings is rotatably connected by rotating shaft, two described connecting sheets are fixedly connected with the second end of two described semi-rings respectively, described connecting sheet is provided with through hole, and two described semi-rings are fixed through described through hole by described connecting bolt.
Preferably, the medial extremity of described first retaining ring contacts with the medial extremity of described second retaining ring, and its surface of contact is provided with sealing rubber ring.
The beneficial effects of the utility model are:
Two fixing oil that the utility model is used for petroleum transportation pipeline are appointed and are threaded that to reach first time fixing by the male conical interface of the first pipeline and second pipe end face and recessed cone-shaped interface, reached fixing for the second time by the extenal fixation ring outside the first retaining ring and the second retaining ring, thus make the unconventional and unrestrained object of fixing to twice of oil, avoid it to occur loosening thus causing leakage of oil.
Accompanying drawing explanation
Fig. 1 is sectional view of appointing for the two fixing oil of petroleum transportation pipeline described in the utility model;
Fig. 2 is profile of appointing for the two fixing oil of petroleum transportation pipeline described in the utility model.
