Utility model content
In order to solve the above technical problems, the utility model provides a kind of chuck expansion joint with self-limiting mechanism, not only
Expansion joint outside dimension can be reduced, reduce expansion joint cost, meet that line temperature compensation requires, and can carry out limiting certainly
Position, reach the purpose of safe handling.
To realize above-mentioned technical purpose, used technical scheme is：A kind of chuck expansion joint with self-limiting mechanism,
Provided with internal bellows and outer corrugations pipe, the both ends of internal bellows connect import tube assembly and outlet tube assembly respectively,
Outlet tube assembly overcoat is provided with outer corrugations pipe, is internally arranged with outer tube outside bellows, one end of outer tube is sealedly and fixedly connected
In import tube assembly, the other end of outer tube is connected with the left adapter of outer corrugations pipe one end, and the other end of outer corrugations pipe leads to
Cross right adapter component sealing to be fixed in outlet tube assembly, internal bellows, outer tube and outer corrugations pipe surround chuck medium sky
Between, the connection tube assembly being connected with chuck dielectric space is provided with outer tube, is also fixed with side by side in outlet tube assembly
Two spacing rings, limiting plate is provided between two spacing rings, the thickness of limiting plate is less than the spacing between two spacing rings, limit
One end of position plate is connected with outer tube wall, and the other end of limiting plate is on-fixed end, and the extreme lower position at on-fixed end is less than spacing
The top side location of ring, limiting plate move with the contraction or expansion of outer corrugations pipe between two spacing rings.
The outside of outer corrugations pipe described in the utility model is additionally provided with the outer shield including outer corrugations pipe is shrouded.
The utility model beneficial effect is：
The expansion joint is used from spacing all-sealed structure, and outer corrugations pipe and internal bellows axile displacement are set, outside
The ripple root diameter and external diameter of bellows can be substantially reduced, and stress situation is improved when outer corrugations pipe works, and is advantageous to carry
The fatigue life of high outer corrugations pipe, and outer corrugations tube material consumption greatly reduces.Outer corrugations pipe is located at outer shield
Inside, prevent occurring damaging and damage during transport, installation, use.Twice are provided among inside and outside bellows
Spacing ring, expansion joint maximum displacement can be limited by two spacing rings, prevent bellows from carry shifting occur, avoid brokenly
It is bad.

Embodiment
The present invention is illustrated with reference to the drawings and specific embodiments, still, the invention is not limited in these embodiments,
It can be additionally used in other pipelines for having same condition of work.
A kind of chuck expansion joint with self-limiting mechanism, provided with internal bellows 5 and outer corrugations pipe 9, internal ripple
The both ends of pipe 5 connect import tube assembly 2 and outlet tube assembly 12, import tube assembly 2, internal bellows 5 and outlet group respectively
Part 12 forms the interior media flowing space.For convenience of the installation of expansion joint, suction flange 1 can be connected at the end of import tube assembly 2, can
In the outlet end connection outlet flange 13 of tube assembly 12.Outer tube 6 is internally arranged with outside bellows 5, one end sealing of outer tube 6 is fixed
Be connected in import tube assembly 2, outer corrugations pipe 9 be arranged with outside outlet tube assembly 12, this kind of structure by outer corrugations pipe and
Internal bellows axile displacement is set, and the ripple root diameter and external diameter of outer corrugations pipe can substantially reduce, and effectively reduce outside
The working stress of bellows, be advantageous to increase outer corrugations pipe service life.Expansion joint outer corrugations pipe diameter can drop significantly
It is low, bellows material consumption is saved, reduces expansion joint cost.
The other end of outer tube 6 is connected by limiting plate 17 with the left adapter 8 of the one end of outer corrugations pipe 9, outer corrugations pipe 9
