Description
Technical field
The utility model relates to a kind of steel pipe joint.
Background technique
At present, in building field or petroleum transportation field, pipe coupling is generally permanent joint link, and this just causes the pipeline when earthquake to produce fracture, affects the normal work of water supply line, for life brings impact.
Model utility content
The purpose of this utility model is the defect overcoming prior art, provides a kind of steel pipe joint, and it is simple that it possesses structure, telescopic feature.
To achieve these goals, the technological scheme taked of the utility model is as follows:
A kind of steel pipe joint, it comprises inner and outer tubes, described interior pipe comprises inner tubule and extra heavy pipe in being connected with described inner tubule, the free end of described inner tubule is provided with interior pipe flange, on described inner tubule, movable sheath is equipped with limited cover, described limited cover is provided with connecting screw hole, described interior extra heavy pipe radial direction is provided with two or more groove, seal ring is equipped with in described groove, the outer tubule that described outer tube comprises outer extra heavy pipe and is connected with described outer extra heavy pipe, the free end of described outer extra heavy pipe is provided with adpting flange, described adpting flange is provided with the corresponding screw of described connecting screw hole, the free end of described outer tubule is provided with outer pipe flange, it is inner that described inner tubule activity is inserted in described outer extra heavy pipe, described limited cover is connected by the screw rod be inserted in described connecting screw hole and described screw with described adpting flange, the external diameter of described interior extra heavy pipe is equal with the internal diameter of described outer extra heavy pipe, the internal diameter of described inner tubule is equal with the internal diameter of described outer tubule.
Compared with prior art, the beneficial effect acquired by the utility model is as follows:
The utility model inner tubule can free-extension in extra heavy pipe outside, due to the setting of seal ring, ensures that the liquid in pipeline does not outflow.Ensure that pipeline junction adjustability is large, meet the fine setting of docking pipeline, and effectively reduce the damage of pipeline in earthquake, it is simple that the utility model possesses structure, telescopic feature.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In the accompanying drawings: pipe flange, 21 outer extra heavy pipes, 22 outer tubules, 23 adpting flanges, 24 screws, 25 outer pipe flanges, 3 seal rings, 4 limited covers, 41 connecting screw holes in extra heavy pipe, 13 grooves, 14 in 11 inner tubules, 12.
Embodiment
Below in conjunction with accompanying drawing, detailed further describing is carried out to the utility model.
As shown in Figure 1, a kind of steel pipe joint, it comprises inner and outer tubes, described interior pipe comprises inner tubule 11 and extra heavy pipe 12 in being connected with described inner tubule 11, the free end of described inner tubule 11 is provided with interior pipe flange 14, on described inner tubule 11, movable sheath is equipped with limited cover 4, described limited cover 4 is provided with connecting screw hole 41, described interior extra heavy pipe 12 radial direction is provided with two or more groove 13, seal ring 3 is equipped with in described groove 13, the outer tubule 22 that described outer tube 2 comprises outer extra heavy pipe 21 and is connected with described outer extra heavy pipe 21, the free end of described outer extra heavy pipe 21 is provided with adpting flange 23, described adpting flange 23 is provided with the screw 24 corresponding with described connecting screw hole 41, the free end of described outer tubule 22 is provided with outer pipe flange 25, it is inner that the activity of described inner tubule 11 is inserted in described outer extra heavy pipe 21, described limited cover 4 is connected by the screw rod be inserted in described connecting screw hole 41 and described screw 24 with described adpting flange 23, the external diameter of described interior extra heavy pipe 12 is equal with the internal diameter of described outer extra heavy pipe 21, the internal diameter of described inner tubule 11 is equal with the internal diameter of described outer tubule 22.
In use, inner tubule is planted in outer extra heavy pipe, limited cover 4 and adpting flange 23 are fixed by the screw rod (not shown) then by being inserted in connecting screw hole and screw inside, inner tubule can free-extension in outer extra heavy pipe again, owing to being provided with seal ring, the proper flow of liquid can being ensured and do not leak.Limited cover is limit structure, after interior extra heavy pipe contacts with limited cover, cannot elongate again, avoids interior pipe to deviate from.
The above mode of execution is only preferred embodiment of the present utility model, and is not the exhaustive of the feasible enforcement of the utility model.For persons skilled in the art, to any apparent change done by it under the prerequisite not deviating from the utility model principle and spirit, all should be contemplated as falling with within claims of the present utility model.
