Sleeve compensator

Technical Field

The utility model relates to a compensator technical field specifically is a sleeve compensator.

Background

The traditional sleeve compensator has the obvious characteristics of simple structure, strong bearing capacity, large axial compensation capacity and the like, is called a tubular expansion joint, is a compensation device of a hot fluid pipeline, is mainly used for absorbing and compensating axial thermal expansion displacement generated after a linear pipeline is arranged in an auxiliary mode, is a compensator directly installed in any pipeline for conveying non-corrosive unidirectional or multidirectional fluid, is widely used in conveying pipelines in industries such as town heating, metallurgy, mines, power generation, petrochemical industry, buildings and the like, and mainly comprises a sleeve (core pipe), a shell, a sealing material and the like.

In view of the fact that a conventional sleeve compensator is easily damaged irreversibly by excessive compensation deformation during axial compensation and also affects the sealing effect of the sleeve compensator, a sleeve compensator is proposed to solve the above problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a sleeve compensator to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: a sleeve compensator comprises an inner pipe and an outer pipe, wherein the outer pipe is coaxially sleeved on the inner pipe, a first flange is fixedly sleeved outside the inner pipe, and a second flange is fixedly sleeved outside the outer pipe, the first flange and the second flange are connected through a bolt assembly, a group of first annular plates are arranged in a gap between the inner pipe and the outer pipe, and two first ring plates are fixed on the inner wall of the outer tube, the adjacent sides of the two first ring plates are provided with second ring plates, and two second ring plates are fixedly sleeved on the outer wall of the inner pipe, a packing layer is arranged in a gap between the adjacent first ring plates and the second ring plates, a third ring plate is arranged between the two second ring plates, and the third annular plate is fixedly arranged on the inner pipe wall of the outer pipe, the two second annular plates are fixedly connected with the same inserted bar, and the inserted bar runs through the third annular plate, and the parts of the inserted bar, which are positioned at the two sides of the third annular plate, are respectively provided with a first spring and a second spring.

Preferably, the elastic pressure of the first spring and the elastic pressure of the second spring are towards the third ring plate.

Preferably, the inserted rods are distributed on the second ring plate in an annular array.

Preferably, the filler layer is an elastic sealing layer.

Preferably, the same limiting sleeve is sleeved at the joint end of the outer pipe, the transition sleeve and the inner pipe.

Compared with the prior art, the beneficial effects of the utility model are that: establish the first spring and the second spring that are balanced effort between interior outer tube, the sleeve compensator is difficult to produce irreversible damage because excessive compensation warp when carrying out axial compensation, establishes the packing layer of the sealed effect of warping of utensil of group simultaneously, under balanced effort extrusion, guarantees good sealed effect between interior outer tube.

Drawings

Fig. 1 is a sectional structure view of the present invention.

In the figure: the structure comprises an inner pipe 1, an outer pipe 2, a first flange 3, a second flange 4, a bolt assembly 5, a first annular plate 6, a packing layer 7, a second annular plate 8, a third annular plate 9, an inserted rod 10, a first spring 11 and a second spring 12.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: a sleeve compensator comprises an inner pipe 1 and an outer pipe 2, wherein the outer pipe 2 is coaxially sleeved on the inner pipe 1, the outer of the inner pipe 1 is fixedly sleeved with a first flange 3, the outer of the outer pipe 2 is fixedly sleeved with a second flange 4, the first flange 3 and the second flange 4 are connected through a bolt assembly 5, a group of first annular plates 6 are arranged in a gap between the inner pipe 1 and the outer pipe 2, the two first annular plates 6 are fixed on the inner wall of the outer pipe 2, the adjacent sides of the two first annular plates 6 are respectively provided with a second annular plate 8, the two second annular plates 8 are respectively fixedly sleeved on the outer wall of the inner pipe 1, a packing layer 7 is arranged in a gap between the adjacent first annular plates 6 and the second annular plates 8, the packing layer 7 is an elastic sealing layer to realize the sealing deformation performance of the packing layer 7, a third annular plate 9 is arranged between the two second annular plates 8, the third annular plate 9 is fixedly arranged on the inner wall of the outer pipe 2, the two second annular plates 8 are fixedly connected with, and the inserted bar 10 runs through the third annular plate 9, the inserted bar 10 is distributed on the second annular plate 8 in an annular array shape, the parts of the inserted bar 10 positioned at the two sides of the third annular plate 9 are respectively provided with a first spring 11 and a second spring 12, the elastic pressure of the first spring 11 and the elastic pressure of the second spring 12 are respectively towards the second annular plate 8 at the adjacent outer side end, when the inner pipe is axially compensated to generate a telescopic effect, under the elastic acting force of the first spring 11 and the second spring 12, the inevitable damage caused by over-compensation is avoided.
