One side end carries out axial limiting by protruding ring B.
The sealing further includes an outer wall connection shell, the cladding ring as a further improvement of the utility model,
Lateral wall on be provided with an annular embedding groove, the center of embedding groove is located at the axial middle part of cladding ring, and the outer wall connects
Body contact includes an annular shell ontology, is each provided with the sealing of a throat structure at the both ends of shell ontology；The shell sheet
An annular inlay protrusion is provided on the inner wall of body, the inlay protrusion is embedded into embedding groove above-mentioned.
The outer wall connection shell is made of mild steel as a further improvement of the utility model,.
The connection inner casing is made of stainless steel as a further improvement of the utility model, and the exceptionally shell uses
Mild steel is made.
The beneficial effects of the utility model are:
1, the utility model devises a kind of connector using stainless steel inner tube and steel outer tube structure, wherein in stainless steel
The processing stage of pipe is lower, and inner wall is more complete, by the fold part of end for close between stainless steel inner tube
Envelope connection, sealing effect are good；A sealing ring aid part is naturally constituted between two outer tubes of this structure, does not need to pass through vehicle
It the modes such as cuts to process outer tube, it is at low cost, and also the fixed performance of sealing ring is strong.
2, outer diameter of the utility model by protruding ring B slightly larger than exceptionally shell, allows stainless steel inner tube and protruding ring B
Form good sealing.
3, outer wall connection shell can carry out a step guarantee entirely for connection tubing between fixed effect, to tubing outside
Being fixedly connected between wall also may further ensure that sealing effect, while entire outer wall connection shell is fixed on the sealing element of rubber
On, the shake of outer tube can be absorbed.
