Abstract
The utility model discloses a high temperature resistant rectangle expansion joint, including end pipe, middle takeover, bellows, filler, the end pipe is including the cover interior sleeve pipe of first circular outer tube, first rectangle together, the middle cover interior sleeve pipe of the circular outer tube of second, second rectangle together of taking over, the middle go -and -return of taking over separates and arranges the end pipe, and the straight -edge section at bellows both ends suit and fixed connection respectively forms the compensation structure of two series connection on first circular outer tube, the circular outer tube outer wall of second, during first rectangle endotheca outside of tubes wall stretches into second rectangle endotheca pipe orifice, and clearance fit, the further improvement lies in: the bellows is formed by thin wall metal plate suppression more than two -layer, be equipped with the lantern ring on the bellows straight -edge section outer wall, the circular outer tube welded connection of the lantern ring, bellows straight -edge section, first circular outer tube or second forms and reinforces the joint in an organic whole. The utility model discloses structural strength is high, and is high temperature resistant, long service life.
Description
Technical field
The utility model is related to a kind of pipe safety device, and specifically, the utility model is related to a kind of rectangular expansion joint.
Background technology
In the solid-granular material conveyance conduit of the industries such as large-scale steam power plant, cement and smelting iron and steel, frequently with rectangular expansion
Section plays the effect absorbing or compensating.The major defect of the rectangular expansion joint of prior art is：Filler is easily from the first rectangle
It is lost in pipeline in inner sleeve, the gap of the second rectangle inner sleeve, bellows resistance to elevated temperatures is poor, easily lost efficacy, service life
Short.
Content of the invention
The utility model is directed to the deficiencies in the prior art, proposes one kind and can significantly improve bellows resistance to elevated temperatures, significantly
The high temperature resistant rectangular expansion joint increasing the service life.
The utility model is achieved through the following technical solutions technical goal.
High temperature resistant rectangular expansion joint, including end pipe, middle adapter, bellows, filler；Described end pipe is included in the first rectangle
The first round jacket pipe that sleeve pipe, the first rectangle inner sleeve outer wall section extend radially outwardly and bending is formed；In described indirectly
Between the axial direction that pipe includes the second rectangle inner sleeve, two parts of the second rectangle inner sleeve pipe outer wall extend radially outwardly and bending is formed
Every arrangement, two opposite the second round jacket pipes；Described middle adapter two ends arranged for interval end pipe, the straight flange at bellows two ends
Section is set with and is fixedly connected on the first round jacket pipe, in the second round jacket pipe outer wall, forms the compensation of two series connection
Structure；It is provided with filler in described ripple tube cavity；It thes improvement is that：Described first rectangle inner sleeve pipe outer wall stretches into the second square
In shape inner sleeve pipe orifice, and gap cooperation.
In said structure, described bellows is formed by the compacting of two-layer above thin metal plate.
In said structure, described bellows straight section outer wall is provided with the collar；The described collar, bellows straight section, first
Round jacket pipe or the second round jacket pipe are welded to connect in one, form reinforcing joint.
In said structure, the material of described filler is alumina silicate heat-preservation cotton.
The utility model compared with prior art, has the positive effect that：
1. the first rectangle inner sleeve pipe outer wall stretches in the second rectangle inner sleeve pipe orifice, and gap cooperation, significantly improves ripple
The sealing of tube cavity, the filler in ripple tube cavity not easily runs off, and so, significantly improves bellows resistance to elevated temperatures, significantly
Increase the service life.
2. bellows is formed by the compacting of two-layer above thin metal plate, significantly improves the structural strength of bellows, further
Extend bellows service life.
3. bellows straight section outer wall is provided with the collar, the collar, bellows straight section, the first round jacket pipe or the second circle
Shape outer tube is welded to connect in one, forms reinforcing joint, so, significantly improves bellows and end pipe, middle adapter junction
Structural strength.
4. the material of filler is alumina silicate heat-preservation cotton, and heat insulation and preservation effect is good.

The axially spaced-apart cloth that shape inner sleeve 5.1, two parts of the second rectangle inner sleeve 5.1 outer wall extend radially outwardly and bending is formed
Put, opposite two the second round jacket pipes 5.2；Middle adapter 5 two ends arranged for interval end pipe 1, the straight section at bellows 3 two ends
It is set with and is fixedly connected on the first round jacket pipe 1.2, on the second round jacket pipe 5.2 outer wall, form two series connection
Collocation structure；It is provided with filler 4, in the present embodiment, the material of filler 4 is alumina silicate heat-preservation cotton in bellows 3 inner chamber；First rectangle
Inner sleeve 1.1 outer wall stretches in the second rectangle inner sleeve 5.1 endoporus, and gap cooperation.
Bellows 3 straight section outer wall is provided with the collar 2；The collar 2, bellows 3 straight section, the first round jacket pipe 1.2 or
Second round jacket pipe 5.2 is welded to connect in one, forms reinforcing joint.
