Abstract
The invention discloses an expansion joint special for a gas pipeline. The expansion joint can be used for effectively absorbing the axial displacement, less horizontal displacement and angular displacement of a pipeline. The technical scheme is realized as follows: the expansion joint special for the gas pipeline comprises flanges (1), a corrugated pipe (2), a guide pipe (3), a pull rod (4), end joint pipes (5) and nuts (6); one end joint pipe (5) is axially connected with each of two ends of the corrugated pipe (2); the guide pipe (3) is arranged in the corrugated pipe (2); one end of the guide pipe (3) is connected onto the inner wall of the end joint pipe (5) at the left end; the other end of the guide pipe (3) is led into the inner cavity of the end joint pipe (5) at the right end; the flanges (1) are arranged at the peripheries of the end joint pipes (5); two ends of the pull rod (4) are fixedly connected with the flanges (1) by the nuts (6). The expansion joint special for the gas pipeline has the following effects that the expansion joint special for the gas pipeline can be used for effectively absorbing the axial displacement, less horizontal displacement and angular displacement of the pipeline caused in the gas pipeline conveying process, the pipeline deformation is reduced and the pipeline leakage is precluded.
Description
Technical field
The present invention relates to expansion joint application, relate in particular to the special expansion joint of gas pipe line.
Background technique
Coal gas is in pipeline transmission engineering, and the interior external pressure thrust producing because of its characteristic of expanding with heat and contract with cold easily causes transmission pipeline distortion even to be leaked.
Summary of the invention
The object of this invention is to provide the special expansion joint of a kind of gas pipe line, effectively the axial displacement of absorption tube line and a small amount of lateral displacement and angular displacement.
To achieve these goals, technological scheme of the present invention is achieved in that the special expansion joint of gas pipe line, it comprises flange 1, bellows 2, honeycomb duct 3, pull bar 4, pipe nipple 5, nut 6, described bellows 2 two ends axially connect respectively a described pipe nipple 5, in described bellows 2, be provided with described honeycomb duct 3, described honeycomb duct 3 one end are connected to described in left end on pipe nipple 5 inwalls, the other end passes into pipe nipple 5 inner chambers described in right-hand member, described pipe nipple 5 is outer is arranged with flange 1, and described pull bar 4 two ends are fixedly connected with described flange 1 by described nut 6.
Further, the special expansion joint of described gas pipe line is that metallic material is made.
Further, described bellows 2, honeycomb duct 3 are stainless steel material making.
Further, the making material of described pull bar 4 can be metal, plastics or rubber.
Further, described pull bar 4 has the six roots of sensation, take the shaft axis of flange 1 as axle, axially connects equably described flange 1.
The present invention has following beneficial effect: the present invention can effectively absorb the pipeline axial displacement that causes in gas pipeline transportation service and a small amount of lateral displacement and angular displacement, reduces pipe deforming, stops pipe leakage.
