Abstract
The utility model discloses a kind of high-temperature bellow compensator, comprise bellows, left guide shell, right guide shell and be connected in the adapter at bellows two ends; Left guide shell is concentric drums enclosed construction, stuffed heat insulated filler in cylinder cavity; Further improve and be: right guide shell is concentric drums enclosed construction, stuffed heat insulated filler in cylinder cavity; Left guide shell port outer wall is hierarchic structure, and the port of right guide shell is provided with seam; The seam gap of right guide shell port is linked in guide shell port, forms maze-type structure.The utility model thermal-protective material can not run off, and heat insulation and preservation effect is good, can not cause bellows because of high temperature action premature failure; Can not produce the problem that thermal-protective material flow ipe causes medium pollution in pipe yet.
Description
Technical field
The utility model relates to pipeline compensator, relates in particular to a kind of corrugated expansion joint.
Background technique
In pipeline, configuring corrugated expansion joint is for absorbing or compensating axial distortion and end thrust, to protect pipeline safe operation.For the pipeline of carrying high temperature media, in order to protect bellows, the corrugated expansion joint of prior art filling with insulation material in cavity between bellows and guide shell, forms thermal insulation structure.This thermal insulation structure can play thermal insulation function, but due to cavity between bellows and guide shell not exclusively sealing, thermal-protective material easily runs off from gap, affect on the one hand heat insulation and preservation effect, can cause bellows because of high temperature action premature failure, on the other hand, thermal-protective material flow ipe, causes the pollution of medium in pipe.
Summary of the invention
The utility model, for the deficiencies in the prior art, proposes good, the reliable high-temperature bellow compensator of a kind of heat insulation and preservation effect.
The utility model is achieved through the following technical solutions technical goal.
High-temperature bellow compensator, comprises bellows, left guide shell, right guide shell and is connected in the adapter at bellows two ends; Its improvements are: described left guide shell is concentric drums enclosed construction, stuffed heat insulated filler in cylinder cavity.
In said structure, described right guide shell is concentric drums enclosed construction, stuffed heat insulated filler in cylinder cavity.
In said structure, described left guide shell, the mutual fit of right guide shell.
In said structure, described left guide shell port outer wall is hierarchic structure, and the port of right guide shell is provided with seam; The seam gap of described right guide shell port is linked in guide shell port, forms maze-type structure.
The utility model compared with prior art, has following good effect:
1. left guide shell is concentric drums enclosed construction, stuffed heat insulated filler in cylinder cavity, and like this, thermal-protective material can not run off, and heat insulation and preservation effect is good, can not cause bellows because of high temperature action premature failure; Can not produce the problem that thermal-protective material flow ipe causes medium pollution in pipe yet.
2. right guide shell is concentric drums enclosed construction, and stuffed heat insulated filler in cylinder cavity, can make heat insulation and preservation effect better.
3. the seam gap of right guide shell port is linked in guide shell port, forms maze-type structure, more effectively stops high temperature media to enter in bellows, and heat insulation and preservation effect is better.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments below.
The compensator of high-temperature bellow shown in accompanying drawing, comprises bellows 2, left guide shell 3, right guide shell 4 and is connected in the adapter 1 at bellows 2 two ends; Left guide shell 3 is concentric drums enclosed construction, stuffed heat insulated filler 5 in cylinder cavity, and right guide shell 4 is concentric drums enclosed construction, stuffed heat insulated filler 5 in cylinder cavity.
In the present embodiment, left guide shell 3 port outer walls are hierarchic structure, and the port of right guide shell 4 is provided with seam; The seam gap of right guide shell 4 ports is linked in guide shell 3 ports, forms maze-type structure.
Claims (4)
