Abstract
The utility model discloses a kind of metal bellows, including metal pipe-wall, described metal pipe-wall includes inner tubal wall and outer tube wall, and metal pipe-wall is annular corrugated.This utility model, easily constructs, and frost resistance is strong, is not easily broken, its annular corrugated tube wall has good non-deformability, and by arranging corrosion-resistant coating so that it is there is good corrosion resistance, extend its service life, hence it is evident that reduce maintenance cost, there is bigger application prospect.
Description
Technical field
This utility model relates to Bellows Technology field, is specially a kind of metal bellows.
Background technology
At present, existing bellows type has two big classes: a class is metal bellows, is through extruded by metallic plate,
Then welding processing completes, and sometimes added with inner liner, prevents contamination of products, and this wavy metal tubular elastic (power) is very big,
With the presence of stress between pipeline and pipeline or between pipeline and equipment, and self cannot eliminate pipeline enclosure draw (answering) power, make
Equipment creates extra-stress, thus affects the properly functioning of equipment, especially pipe stress is required strict equipment, as right
The properly functioning meeting of weighing system causes the biggest impact.Another kind of is non-metal bellows, be by nonmetallic materials such as rubber,
Plastics, chemical fabric etc. manufacture molding, although it can eliminate pipe stress, but exist the most aging, and intensity is the highest, often occur broken
Splitting so that causing the technological deficiency of leakage accident, meanwhile, nonmetal corrugated tube is also easy to remain material on corrugated internal wall, enters
And cause contamination of products.
Utility model content
The purpose of this utility model is to provide a kind of metal bellows, with asking of solving to propose in above-mentioned background technology
Topic.
For achieving the above object, this utility model following technical scheme of offer: a kind of metal bellows, including metal tube
Wall, described metal pipe-wall includes inner tubal wall and outer tube wall, and metal pipe-wall is annular corrugated.
Preferably, it is provided with puigging between said inner tube wall and outer tube wall.
Preferably, inside said inner tube wall, it is provided with interior corrosion-resistant coating, outside described outer tube wall, is provided with outer corrosion-resistant coating.
Compared with prior art, the beneficial effects of the utility model are: this utility model is easily constructed, and frost resistance is strong, no
Easily rupturable, its annular corrugated tube wall has good non-deformability, and by arranging corrosion-resistant coating so that it is have the most anti-
Corrosive nature, extends its service life, hence it is evident that reduce maintenance cost, has bigger application prospect；It is installed on electromotor
Between exhaust manifold and depurator, many vibrations can be absorbed, reduce noise, compensation installation deviation and expand with heat and contract with cold, just
Just install and extend the effect in exhausting silencer system life-span；Using ripple forming technology, flexible, air-tightness is good；Product structure
Various informative, length is unrestricted, can meet the needs of different automobile types；Product specification size can be according to customer requirement design system
Make；Rustless steel SUS304 material makes life of product longer；Wave number density is high, lightweight, it is easy to install；Air pollution can be reduced.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is cross-sectional view of the present utility model；
In figure: 1-metal pipe-wall；The outer corrosion-resistant coating of 2-；3-outer tube wall；4-puigging；5-inner tubal wall；Corrosion-resistant coating in 6-.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1-2, a kind of embodiment that this utility model provides: a kind of metal bellows, including metal pipe-wall 1,
Metal pipe-wall 1 includes inner tubal wall 5 and outer tube wall 3, and metal pipe-wall 1 is annular corrugated, sets between inner tubal wall 5 and outer tube wall 3
It is equipped with puigging 4, inside inner tubal wall 5, is provided with interior corrosion-resistant coating 6, outside outer tube wall 3, be provided with outer corrosion-resistant coating 2；Easily execute
Work, frost resistance is strong, is not easily broken, and its annular corrugated tube wall has good non-deformability, and by arranging corrosion-resistant coating, makes
It has good corrosion resistance, extends its service life, hence it is evident that reduce maintenance cost, before having bigger application
Scape；It is installed between enmgine exhaust and depurator, many vibrations can be absorbed, reduce noise, compensation installation partially
Difference and the effect in exhausting silencer system life-span of expanding with heat and contract with cold, conveniently install and extend；Use ripple forming technology, flexible, gas
Close property is good；Product structure is various informative, and length is unrestricted, can meet the needs of different automobile types；Product specification size can basis
Customer requirement manufactures and designs；Rustless steel SUS304 material makes life of product longer；Wave number density is high, lightweight, it is easy to install；Can
Reduce air pollution.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new
Type.Therefore, no matter from the point of view of which point, all should regard embodiment as exemplary, and be nonrestrictive, this practicality is new
The scope of type is limited by claims rather than described above, it is intended that by the containing of equivalency in claim that fall
All changes in justice and scope are included in this utility model.Should not be considered as any reference in claim limiting
Involved claim.
