Description
Technical field
The utility model relates to a kind of assembling pipe joint, particularly the flexible connection set of a kind of petroleum pipeline.
Background technique
Pipeline extension device is the link that the dimensional changes that causes owing to expanding with heat and contract with cold during pipeline connects is recompensed.What pipeline extension device was the most frequently used has two kinds, and a kind of is rubber tubing expansion bend, and another kind is metallic conduit expansion bend.The bearing temperature of rubber tubing expansion bend is lower, bear pressure less, the main feature of metallic conduit expansion bend is that flexible compensation amount is large, bearing temperature is high, bear pressure large, current metallic conduit expansion bend generally adopts stainless steel to make bellows, when pipe expansion, corrugated stainless steel tubing is produced to impact force.But the axial displacement that more difficult adjustment pipeline occurs.
Chinese patent literature number: CN 203297808 U, patent name is < < sleeved pipe telescoping devices > >, comprise sleeve pipe, platen, telescopic pipe, platen is equipped with in telescopic pipe one end, the other end cover has sleeve pipe, described expansion bend is separately provided with guiding trestle and is installed between two fixed supports in casing linear section, described platen periphery is provided with a grade bar, this pipeline extension device connects unstable, in using process, be subject to force-extension easily to cause disconnection, affect normal oil transportation, reduced transfer efficiency, pollute waste.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, a kind of petroleum pipeline connection set that stretches is provided, flexible connection set has facilitated the installation and removal of each component widely, improved efficiency of assembling, easy to connect between each component, reliable, firm, good seal performance.
Its technological scheme is: comprise connection-peg, butt joint, locking ring, pressure ring, threaded sleeve, pipeline, one end of pipeline is connection-peg, the other end of pipeline is butt joint, the end of described connection-peg is provided with grafting boss, described grafting boss is provided with threaded sleeve, the inside, one end of butt joint is provided with docking recess, docking recess and connection-peg cooperatively interact, the end of described butt joint is provided with end face boss, described end face boss extends to the inside tight lock part and is connected boss, the radial dimension of tight lock part is less than end face boss and the radial dimension that is connected boss, described tight lock part is provided with locking ring, the outside of locking ring is provided with pressure ring, described connection boss is provided with boss outside thread, the interior edge face that connects boss is provided with boss on the shoulders.
Above-mentioned locking ring is external tooth torus, and described pressure ring is internal gear groove ring, and external tooth torus and internal gear groove ring cooperatively interact and guarantee radially not rotate.
The inside of above-mentioned butt joint is provided with seal ring.
The beneficial effects of the utility model are: flexible connection set has facilitated the installation and removal of each component widely, improved efficiency of assembling, easy to connect between each component, reliable, firm, good seal performance, bearing capacity is large, can be easily, carry out rapidly connection and the transposing of pipe joint, locking ring is external tooth torus, pressure ring is internal gear groove ring, and external tooth torus and internal gear groove ring cooperatively interact and guarantee radially not rotate, and avoids the damage of the pipeline that axial tension causes.
