Description
Technical field
The utility model is related to corrugated expansion joint, specially interior external pressure anti-slip compensator.
Background technology
A kind of expansion joint made of corrugated expansion joint metal bellows used for expansion joint.It can stretch in the axial direction,
Allow a small amount of bending.Metal corrugated expension joint is the displacement because of generation of expanding with heat and contract with cold for compensation conduit system.For pipeline
Support bracket fastened pipeline section between two equipment should not be set, corrugated expansion joint may be used to absorb its axial displacement.It is existing
Corrugated expansion joint has the following disadvantages：Binding site gap between inner tube and casing or reducer pipe is excessive, if pipeline
In be fluid media (medium) if, be easy at the position generate vortex, which adds the pressure loss of fluid media (medium), in addition,
Connecting portion in existing compensator between inner tube, casing and bellows is mostly attached by connecting tube or intermediate tube,
Link position mostly substantially reduces the sealing performance for causing pipeline, and connecting portion is easily damaged in use, in ripple
Traditional pull rod is relied solely on when pipe is subjected to displacement it is difficult to ensure that connecting portion does not pull, is particularly encountering big displacement
In the case of, situation about pulling is more frequent.
Utility model content
To solve the above-mentioned problems, the purpose of this utility model is to carry a kind of interior external pressure anti-slip compensator, the compensator
Core pipe with casing is mutually socketed and is integrated, and in belled position anti-slip structure, pulling between pipeline is effectively ensured.
The technical solution that the utility model is taken to solve the above-mentioned problems is：Interior external pressure anti-slip compensator, including
Core pipe, the bellows for being set in core pipe excircle and the casing being connect with bellows, the core pipe one end are set along excircle
There are snap ring, casing one end to be socketed in core pipe after sliding through snap ring, and the position-arresting ring by being arranged on the casing end inner periphery
Anti-pull off body is formed with snap ring, the tube wall circumference of the core pipe another side is fixedly installed retainer ring, the bellows one
End is fixedly connected in retainer ring, and the other end is connected with the end wall of casing, to drive bellows by sliding axially for casing
Axial stretching, the free end of casing and core pipe is respectively connected with flange.
Protection pipe is arranged in described sleeve pipe and retainer ring, described protection pipe one end is fixed on retainer ring ring wall,
The other end is placed on casing, and the tube wall inner periphery that is located on casing of protection pipe is provided in the axial direction with limiting slot, outside described sleeve pipe
The spacing ring to match with limiting slot is provided in circumferential wall, is resisted against in limiting slot with the axial direction of limiting boot at the top of spacing ring
Displacement spacing.
Preferably, the spacing ring roof is embedded with elastic seal ring.
Preferably, elastic sealing bands are provided between the retainer ring external annulus and casing connection.
Preferably, described sleeve pipe one end passes through connecting tube and the flanged joint at the end.
Preferably, described sleeve pipe and retainer ring end are connect by otic placode with bellows.
Compared with prior art, the utility model has the advantages that：
First, interior external pressure anti-slip compensator described in the utility model, the snap ring on position-arresting ring and core pipe on casing
Between formed anti-slip structure, casing can be effectively prevent to be pulled from core pipe, this compared with the pull rod that traditional limitation pulls,
It is better, in addition, this structure to form socket connection between casing and core pipe, Hard link is avoided, can effectively be protected
Demonstrate,prove the sealing performance of pipeline.
Second, interior external pressure anti-slip compensator described in the utility model is further set on casing between protection pipe
The position limiting structure of limiting boot total displacement length has been put, has protected the limiting slot of inside pipe wall and the spacing ring phase interworking of sleeve outer wall
It closes, the shift length of casing is limited in the length range of limiting slot, the transition of bellows can effectively be avoided to stretch or receive
Contracting extends the service life of bellows.
