Abstract
The utility model discloses an elastic tensioning structure of special corrugated tube compensator for gas pipeline, which is disposed between the left end flange and the right end flange of corrugated tube compensator or outer side of the corrugated tube, comprising a push rod, a shaft pin, a compression spring, a sleeve tube, a joint bearing, a separating ring and a connecting screw; the push rod and the sleeve tube are coaxially sleeved; the right end of the push rod is vertically and fixedly connected with the shaft pin; the left end of the sleeve tube is provided with an axial long slot, so as to match with the shaft pin; the compression spring is disposed between the right flange of the sleeve tube and the shaft pin; the left end of the push rod and the right end of the sleeve tube are respectively connected with the side walls of the left flange and the right flange by the joint bearing, the separating ring and the connecting screw; the elastic tensioning structure of special corrugated tube compensator for gas pipeline is uniformly disposed in same circle having a central line same as the central axis of corrugated tube, the amount is two or three. The utility model has simple structure and low manufacturing cost, the corrugated tube compensator with the utility model can compensate axial displacement and can also compensate large angular displacement.
Description
Technical field
The utility model relates to the corrugated expansion joint field, and specifically, the utility model relates to a kind of corrugated expansion joint tension structure.
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.Existing technology is that the structure that more complicated is set on corrugated expansion joint realizes such compensation, these structure more complicated, and manufacture cost is high.
Summary of the invention
The utility model is to the deficiency of existing technology, proposes a kind of simple in structurely, and low cost of manufacture can the compensating axial displacement, the special-purpose corrugated expansion joint elastic tension of the gas pipeline structure of again can compensate for slower big angular displacement.
The utility model is realized technical goal through following technical proposals.
The special-purpose corrugated expansion joint elastic tension of gas pipeline structure, it is arranged on mainly on the corrugated expansion joint that is made up of left end flange, bellows, right-hand member flange; Its improvements are: the special-purpose corrugated expansion joint elastic tension of said gas pipeline structure is arranged between said left end flange and the right-hand member flange, the bellows outside; It comprises push rod, pivot pin, pressure spring, sleeve, joint shaft bearing, spacer ring, attachment screw; Said push rod, sleeve concentric gap fit; Push rod right-hand member vertical fixing connects 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; The left end of said push rod, the right-hand member of sleeve are connected with left end flange, right-hand member flange sidewall respectively through joint shaft bearing, spacer ring, attachment screw; It is on the same circumference of center line that the special-purpose corrugated expansion joint elastic tension of said gas pipeline even structure is arranged in said bellows core axis, and quantity is 2 or 3.
The further technological scheme of the utility model is: the special-purpose corrugated expansion joint elastic tension of said gas pipeline number of structures is 3.
The utility model compared with prior art has following good effect:
1. simple in structure, make easily.
2. be provided with the elastic tension structure between left end flange and the right-hand member flange; Be connected through joint shaft bearing between elastic tension structure 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 corrugated expansion joint be provided with the utility model can the compensating axial displacement, again can the big angular displacement of compensate for slower.

Fig. 2 is Fig. 1 left view.
Embodiment
Below according to accompanying drawing and combine embodiment that the utility model is described further.
The special-purpose corrugated expansion joint elastic tension of gas pipeline shown in accompanying drawing 1, the accompanying drawing 2 structure; It is arranged between the left end flange 1 and right-hand member flange 10 of corrugated expansion joint, bellows 6 outsides; Comprise push rod 5, pivot pin 7, pressure spring 8, sleeve 9, joint shaft bearing 3, spacer ring 2, attachment screw 4; Push rod 5, sleeve 9 concentric gap fits, push rod 5 right-hand member vertical fixing connect pivot pin 7, and sleeve 9 left ends are provided with axial elongated slot and pivot pin 7 Spielpassung; Be provided with pressure spring 8 between sleeve 9 right-hand member flanges and the pivot pin 7; The right-hand member of the left end of push rod 5, sleeve 9 is connected with left end flange 1, right-hand member flange 10 sidewalls respectively through joint shaft bearing 3, spacer ring 2, attachment screw 4; It is on the same circumference of center line that the special-purpose corrugated expansion joint elastic tension of gas pipeline even structure is arranged in said bellows 6 central axis; Quantity is 2 or 3; Present embodiment is 2, but the special-purpose corrugated expansion joint elastic tension of general gas pipeline number of structures when being 3 effect best.
The utility model is arranged between left end flange 1, the right-hand member flange 10; Be connected through joint shaft bearing 3 between left end flange 1, the right-hand member flange 10; Left end flange 1, right-hand member flange 10 can be realized the rotation than wide-angle like this; Make that the corrugated expansion joint be provided with the utility model can the compensating axial displacement, again can the big angular displacement of compensate for slower.
