Abstract
The invention discloses an elastic tension type corrugated pipe compensator which comprises a left end flange, a corrugated pipe, a right end flange, an elastic tensioning device, oscillating bearings, space rings and supporting shafts, wherein the corrugated pipe is coaxially and fixedly connected with the left end flange and the right end flange to form a compensating structure; the elastic tensioning device is arranged between the left end flange and the right end flange and outside the corrugated pipe, and the elastic tensioning device comprises a draw bar, a shaft pin, a compression spring and a sleeve; both ends of the elastic tensioning device are respectively connected with side walls of the left end flange and the right end flange through the oscillating bearings, the space rings and the supporting shafts; and one ends of the left end flange and the right end flange, which face toward outside, are provided with boss or stop mouth connecting structures connected with a pipeline. The elastic tension type corrugated pipe compensator provided by the invention has a simple structure, not only can compensate axial displacement, but also can compensate larger angular displacement, is simple and quick to be connected with the pipeline and is especially applicable to a gas transportation pipeline.
Description
Technical field
The present invention relates to a kind of pipe safety device, specifically, the present invention relates to a kind of pipeline compensator.
Background technique
In gas pipeline, often dispose corrugated expansion joint with the compensation piping displacement, the compensation tache that has had both needed the compensating axial displacement, needed the big angular displacement of compensate for slower again.Need to realize such compensation, the corrugated expansion joint structure more complicated of existing technology, on the other hand; The two ends of the corrugated expansion joint of existing technology with generally adopt flange, bolt to connect of pipeline or be welded to connect; Linkage structure is complicated, connects time-consumingly, changes and takes a lot of trouble.
Summary of the invention
The present invention is directed to the deficiency of existing technology, propose a kind of simple in structure, can the compensating axial displacement, again can the big angular displacement of compensate for slower, be connected simply with pipeline, elastic tension formula corrugated expansion joint efficiently.
The present invention realizes technical goal through following technical proposals.
Elastic tension formula corrugated expansion joint, it comprises left end flange, bellows, right-hand member flange; Said bellows with the left end flange, the right-hand member flange is coaxial is fixedly connected, and constitutes collocation structure; Its improvements are: between said left end flange and right-hand member flange, the bellows outside is provided with elastic stretching device; Said elastic stretching device comprises pull bar, pivot pin, pressure spring and sleeve; Said pull bar, sleeve concentric gap fit; The pull bar right-hand member is fixedly connected pivot pin, and the sleeve left end is provided with axial elongated slot and pivot pin Spielpassung; Be provided with pressure spring between said sleeve right-hand member flange and the pivot pin, constitute the elastic tension structure; Said elastic stretching device two ends are connected with left end flange, right-hand member flange sidewall respectively through joint shaft bearing, spacer ring, supporting axle; The central axis that said elastic stretching device is evenly arranged in said corrugated expansion joint is on the same circumference of central axis, and quantity is 3.
In the said structure, said left end flange is provided with boss or the seam linkage structure that is connected with pipeline with a right-hand member flange end outwardly.
The present invention compared with prior art has following good effect:
1. simple in structure, make easily.
2. be provided with elastic stretching device between left end flange and the right-hand member flange; Be connected through joint shaft bearing between elastic stretching device two ends and left end flange, the right-hand member flange; Left end flange, right-hand member flange can be realized the rotation than wide-angle like this; Make that the present invention can the compensating axial displacement, again can the big angular displacement of compensate for slower.
3. the left end flange is provided with boss or the seam linkage structure that is connected with pipeline with a right-hand member flange end outwardly, and elastic stretching device makes that corresponding adpting flange closely contact all the time on left end flange and right-hand member flange and the pipeline, connects simply, changes fast.
