Abstract
The invention discloses a kind of high temperature high voltage resistant non-metal expansion joint covering, covering is nonmetallic compound whole vulcanization material；Further improvement lies in that：Covering inner wall is equipped with steel wire；Covering outer wall coats fire resistant coating.High temperature resistant of the present invention, high pressure resistant, air-tightness is good, soft high.
Description
Technical field
The present invention relates to expansion joint flexible connecting material, more particularly to a kind of non-metal expansion joint covering.
Background technology
Non-metal expansion joint is widely used in the high temperature flue gas exhausting pipe line such as steam power plant, steel plant, smeltery, nonmetallic
Expansion joint is flexible coupling by covering realization, and this occasion non-metal expansion joint covering is generally alkali-free glass fiber cloth or ceramics are fine
Wei Bu, the major defect of this non-metal expansion joint covering are：Service life is short under hot environment.
The content of the invention
In view of the deficiencies of the prior art, the present invention proposes a kind of high temperature high voltage resistant that can significantly increase high temperature resistance is nonmetallic
Expansion joint covering.
The present invention is achieved through the following technical solutions technical goal.
High temperature high voltage resistant non-metal expansion joint covering includes covering；It is theed improvement is that：The covering is nonmetallic multiple
Close whole vulcanization material.
In said structure, the covering inner wall is equipped with steel wire.
In said structure, the covering outer wall coats fire resistant coating.
Compared with prior art, the present invention it has the positive effect that：
1st, covering is nonmetallic compound whole vulcanization material so that the present invention has high-air-tightness, high flexibility, high temperature resistant, longevity
The characteristics such as life length.
2nd, covering inner wall is equipped with steel wire, structural rigidity of the present invention and intensity is significantly improved, so as to significantly improve the present invention
Pressure-resistant performance.
3rd, covering outer wall coating fire resistant coating, significantly improves fire protecting performance of the present invention.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Specific embodiment
