Abstract

The present invention relates to a sealed corrugated pipe for a pipeline. A seal ring is arranged between an end joint pipe and a socket end joint pipe, and the outer wall of the end joint pipe and the outer wall of the socket end joint pipe are respectively sheathed with a corrugated pipe; the end joint pipe, the socket end joint pipe, and the corrugated pipes sheathed on the outer wall of the end joint pipe and the outer wall of the socket end joint pipe are covered in a seal pipe, gaps are arranged between the end surface of the seal pipe and the outer wall of the end joint pipe and the socket end joint pipe, a seal space is formed among the seal pipe, the front corrugated pipe, the back corrugated pipe and the outer wall of the end joint pipe and the socket end joint pipe, and a limited slide groove and a guide rail are respectively arranged between the seal pipe and the end joint pipe and between the seal pipe and the socket end joint pipe. The present invention is free from the influence of impurities and precipitates in a pipeline, has the advantages of large telescopic quantity and good compensating effect and can adapt to large temperature changes.

Description

Sealed corrugated pipe for pipeline
Technical field
The present invention relates to a kind of industrial pipeline compensator, especially a kind of bellows.
Technical background
At present, known corrugated pipe for pipeline (compensator) is at outside weldings one bellows of pipeline with the cover interface tube.Its shortcoming is in the pipeline, and the impurity in the medium easily remains in the place, slit between jointing pipe nipple and the bell end adapter, and in the bellows, thereby reduce the dilatability of bellows, not even flexible, the concavo-convex resistance of this outward corrugated tube is big, does not reach the effect of compensation of pipeline.
Summary of the invention
The purpose of this invention is to provide a kind of inside diameter of bel and do not contact the interior medium of pipeline, and contact with external air, be not subjected to impurity and sedimentary influence the in the pipeline, extending amount is big, compensation effect is good, and when being subjected to a side pressure, it can produce the bending of certain radian, thereby compensate, can adapt to the sealed corrugated pipe for pipeline of big temperature variation.
The object of the present invention is achieved like this:
The present invention includes pipe nipple, bell end is taken over, flange, bellows, pipe nipple inserts in the bell end adapter, it is characterized in that: the front end of pipe nipple is an expansion shape mouth, the afterbody that bell end is taken over is a contraction shape mouth, the annular space that forms between contraction shape mouth that the expansion shape mouth of pipe nipple and outer wall thereof and bell end are taken over and inwall thereof is built-in with seal ring, the outer wall that pipe nipple and bell end are taken over is with bellows respectively, sealed pipe with pipe nipple and bell end are taken over and they outer walls overlapped bellows cover within it, before the sealed pipe, between the outer wall that ear end face and pipe nipple and bell end are taken over the slit is arranged, sealed pipe with before, form seal space between the outer wall that latter two bellows and pipe nipple and bell end are taken over, do not pass through medium in the bellows, and be connected with ambient air, before the sealed pipe, ear end face is provided with limit sliding chutes and guide rail respectively and between pipe nipple and the bell end adapter.
The front end of the bellows that the pipe nipple outer wall is overlapped and the welding of its outer wall, ear end face terminal and sealed pipe welds, and bell end is taken over the front-end face welding of the front end and the sealed pipe of the bellows that outer wall overlapped, and terminal and its outer wall welds; The expansion shape mouth of pipe nipple contacts for point with the inwall that bell end is taken over, and bell end is taken over contraction shape mouth and also contacted for point with the outer wall of pipe nipple.
The sealed pipe lower end is provided with drain pipe.
Limit sliding chutes is located on the front and rear end of sealed pipe, and the outer wall that pipe nipple and bell end are taken over is fixed with guide rail separately, cooperates with limit sliding chutes.
Bellows is welded by opening dislocation bourdon tube and clamping plate, the thickness ratio open dislocation spring thickness of pipe of clamping plate.
The thickness of clamping plate is 2-3 times of opening dislocation bourdon tube thickness.
The present invention is owing to adopt said structure, its inside diameter of bel does not contact the medium in the pipeline, and contact with external air, be not subjected to impurity and sedimentary influence the in the pipeline, extending amount is big, compensation effect is good, because the expansion shape mouth of pipe nipple contacts for point with the inwall that bell end is taken over, it also is that point contacts with the outer wall of pipe nipple that bell end is taken over contraction shape mouth, so when being subjected to a side pressure, it can produce the bending of certain radian, thereby compensate, can adapt to big temperature variation, because bellows is formed by opening dislocation bourdon tube and clamping plate, its crushing resistance obviously strengthens in addition.
Description of drawings
Fig. 1 is a plan view of the present invention.
Fig. 2 is a partial side view of the present invention.
Fig. 3 is the structural drawing of bellows.
Embodiment's explanation
Below in conjunction with drawings and Examples the present invention is further described:
See Fig. 1, the front end of pipe nipple 1 is an expansion shape mouth, the afterbody of bell end adapter 5 is a contraction shape mouth, take over the annular space that forms between 5 contraction shape mouth and the inwall thereof at the expansion shape mouth of pipe nipple 1 and outer wall thereof and bell end and be built-in with seal ring 3, the outer wall of pipe nipple 1 and bell end adapter 5 is with bellows 10,4 respectively, sealed pipe 2 with pipe nipple 1 and bell end take over 5 and bellows 10,4 covers that they outer walls overlapped within it, between the outer wall of the front and rear end of sealed pipe 2 and pipe nipple 1 and bell end adapter 5 slit is arranged; The front end of the bellows 10 that pipe nipple 1 outer wall is overlapped and the welding of its outer wall, terminal ear end face with sealed pipe 2 welds, bell end is taken over the front-end face welding of the front end and the sealed pipe 2 of the bellows 4 that 5 outer walls are overlapped, terminal and its outer wall welding make to form seal space between the outer wall of sealed pipe 2 and former and later two bellowss 10,4 and pipe nipple 1 and bell end adapter 5 thus; The expansion shape mouth of pipe nipple 1 contacts for point with the inwall of bell end adapter 5, and it also is that point contacts with the outer wall of pipe nipple 1 that bell end is taken over 5 contraction shape mouths, and when being subjected to a side pressure, it can produce the bending of certain radian, thereby compensates; Do not pass through medium in the bellows 10,4, and be connected, be not subjected to the influence of impurity in the medium with ambient air; Sealed pipe 2 lower ends are provided with drain pipe 7.
See Fig. 2, two limit sliding chutes 9 correspondences are located on the front and rear end of sealed pipe, and the outer wall that pipe nipple and bell end are taken over is fixed with two corresponding guide rail 6 separately, cooperates with two limit sliding chutes 9 respectively, plays a part guiding.
See Fig. 3, bellows 10,4 is welded by opening dislocation bourdon tube 11 and clamping plate 12, and the thickness ratio open dislocation bourdon tube 11 of clamping plate 12 is thick.
The thickness of clamping plate 12 is 2-3 times of opening dislocation bourdon tube 11 thickness.
