Description
Technical field
The utility model relates to a kind of pipeline connecting device, particularly a kind of Telescopic pipeline connection set.
Background technique
Connection between traditional pipeline road needs to be threaded, need to arrange screw thread at transport pipe two ends, undertaken connecting, sealing by joint, not only manufacture cost is high, and once pipeline occurs that leakage problem appears in damage or joint, is often not easy to maintenance and leak detection, pipeline changes difficulty, sealing effect is poor, and workman is large to the maintenance workload of transport pipe, uses inconvenience.It is very inconvenient that the pipeline road of current use couples together, and link easily lost efficacy, and was unfavorable for the raising of oil transportation operating efficiency.
China Patent Publication No. is: CN 202452003 U, patent name is: " petroleum pipeline seal connection ", comprises one section of box cupling, has a ring-type shoulder block in the middle part of box cupling, in the box cupling of ring-type shoulder block both sides, engagement sleeves is filled with an inner seal ring respectively, inner seal ring and box cupling coaxial line; The box cupling inner circle wall conically face of shoulder block both sides, the box cupling inner circle wall outside coned face is arranged respectively connecting thread formation threaded ends; On two pipelines that medial extremity and two inner seal rings offset, engagement sleeves is filled with conical ring seal ring and locks plug respectively from inside to outside, locking plug is connected with said threaded ends, on the outer circumferential face of conical ring seal ring, interval arranges twice exterior seal ring, said inner seal ring is the annular solid of hollow, the inner circle wall of inner seal ring is arranged an annular gap, the cross section of inner seal ring is C font; This sealed connection device for pipeline is connected by box cupling, connects unstable, easily causes pipeline axial displacement, cause pipeline Joint failure, cause oil pipe to reveal, be unfavorable for oil transportation operation.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and provide a kind of Telescopic pipeline connection set, installation efficiency is high, improves installation rate.
Its technological scheme is: comprise joint, pipeline, joint connecting tube, described joint is provided with the first otic placode, first otic placode is provided with earhole, the two ends of joint are respectively equipped with birdsmouth, pipeline is provided with the second otic placode, the birdsmouth connecting tube at joint two ends, the first otic placode on described joint is connected by connecting rod with the second otic placode on pipeline, described joint and the joint of pipeline are provided with seal ring, the external stability fastening piece of seal ring, fastening piece is plugged on connecting rod, and connecting rod is fixed by adjusting nut.
Above-mentioned fastening piece comprises body, and the centre of described body is provided with central through bore, body be respectively equipped with interface up and down, the inner side of body is arc sphere, and interface is serially connected on connecting rod.
Above-mentioned connecting rod is threaded stem.
