Abstract
It is a kind of to prevent the hinge type expansion joint of material abrasion bellows, the end of flow cartridge sets sphere voussoir A in a ring, on the inwall that outlet end pipe is arranged on the sphere voussoir B in a ring that sphere voussoir A is correspondingly arranged, described sphere voussoir A and sphere voussoir B is meshed.By setting the sphere of two engagements, when corner displacement occurs for expansion joint so that bellows cavity is approximately at " closing " state, it is possible to prevente effectively from the abrasion that solid particle medium is caused to bellows.
Description
Technical field
The invention belongs to compensation of pipeline field, particularly relate to a kind of hinge type for preventing material abrasion bellows and expand
Section.
Background technology
Bellows expansion joint is widely used in industries such as oil refining, petrochemical industry, metallurgy and pharmacy, wherein being no lack of
Pipeline medium is the application scenario such as solid granulates catalyst, and it often brings certain abrasion to whole pipeline, especially when
In the case that velocity of medium is higher.Bellows is a kind of flexible shell of thin-walled, should avoid or weaken abrasive media in work
Damage under state to it, Fig. 1 is the structure that generally uses, sets dust-proof cushion in the end of guide shell, and dust-proof cushion is by along circle
Week, the fixation fork of arrangement was fixed with guide shell, and dust-proof cushion is in squeezed state, so as to prevent catalyst from entering in bellows chamber body
Portion, abrasion is caused to bellows.
The structure design for setting dust-proof cushion using guide shell end can prevent catalyst from entering bellows to a certain extent
Inside cavity, but for hinge type expansion joint, when corner displacement occurs for bellows, the gap between guide shell and end pipe
Side reduces, and opposite side increases, and solid state medium can enter bellows inside cavity from the big side in gap.
The content of the invention
In order to solve the above technical problems, present invention offer is a kind of to prevent the hinge type expansion joint of material abrasion bellows, lead to
The design of self structure part is crossed, the pipeline medium with abrasive nature can be prevented to enter bellows interior, and then from avoiding its right
The abrasion that bellows is caused.
To realize above-mentioned technical purpose, the technical scheme used is：It is a kind of to prevent the hinge type of material abrasion bellows
Expansion joint, the head end of the guide shell of hinge type expansion joint is fixedly connected with the inwall of import end pipe, the end and outlet of guide shell
Gap is provided between the inwall of end pipe, the end of guide shell sets sphere voussoir A in a ring, is correspondingly arranged with sphere voussoir A
Sphere voussoir B in a ring be arranged on outlet end pipe inwall on, described sphere voussoir A and sphere voussoir B is meshed.
The sphere voussoir A and sphere voussoir B of the present invention centre of sphere is consistent with the center of bellows.
Present invention has the advantages that：By setting the sphere of two engagements, when corner displacement occurs for expansion joint so that ripple
Line tube chamber is approximately at " closing " state, it is possible to prevente effectively from the abrasion that solid particle medium is caused to bellows.

Embodiment
The invention is not limited in following examples：
As shown in Fig. 2 it is a kind of prevent material wear and tear bellows hinge type expansion joint by end pipe 1, flap 2, ring flat-plate 3, universal
Ring 4, bearing pin 5, bellows 6, water conservancy diversion cartridge module 7, gusset 8 are constituted, and hinge type expansion joint includes unidirectional hinge type expansion joint, compound
Hinge type expansion joint etc., by taking Fig. 2 one-way linkage type expansion joint as an example, the expansion joint structure also includes sphere voussoir A 9, ball
Face voussoir B 10 is constituted, it is possible to prevente effectively from the abrasion that solid particle medium is caused to bellows.
In the hinge type expansion joint of all models, the head end of guide shell 7 is fixedly connected with the inwall of import end pipe 1, is led
The end of flow cartridge 7, which is passed through, to be stretched into after bellows in outlet end pipe 11, and is provided with gap, water conservancy diversion between the inwall with exporting end pipe 11
The end of cylinder 7 sets sphere voussoir A 9 in a ring, and sphere voussoir A9 is integrally formed with guide shell 7, with 9 couples of sphere voussoir A
The sphere voussoir B 10 in a ring that should be set is arranged on the inwall of outlet end pipe 11, and sphere voussoir B10 is welded on the port of export
On the inwall of pipe 11, described sphere voussoir A 9 and sphere voussoir B 10 is meshed.
As shown in Fig. 3,4,5,6, sphere voussoir A 9 and sphere are set on the end of water conservancy diversion cartridge module 7 and outlet end pipe 1
Voussoir B 10, sphere voussoir A 9 are provided with sphere curved surface SR1, and sphere voussoir B 10 is provided with sphere curved surface SR2, and two spheres are mutually nibbled
Close, when corner displacement occurs for expansion joint, sphere curved surface SR1 and sphere curved surface SR2 remains in engagement, and bellows is made all the time
Cavity is approximately at " closing " state, meanwhile, sphere curved surface SR1 and sphere curved surface the SR2 centre of sphere are homocentric at bellows core,
When corner displacement occurs for expansion joint, sphere voussoir B 10 is rotated relative to sphere voussoir A 9 around the common centre of sphere, it is possible to prevente effectively from solid
The abrasion that body granule medium is caused to bellows, can also be prevented effectively from sphere voussoir B 10 with respect to the mill between sphere voussoir A 9
Damage.
