Abstract
The utility model discloses a kind of etch-proof gas pipelines of noise reduction, the outside of the gas pipeline is cased with bellows, silencing cotton is filled between the outer wall of the gas pipeline and the bellows, the gas pipeline is respectively plastic lining, metal layer and anticorrosive paint layer from the inside to the outside.The utility model can be convenient for protection caliber and the diverse gas pipeline of pipeline, improve the soundproof effect of gas pipeline.
Description
Technical field
The utility model is related to combustion gas transport field, more particularly to a kind of etch-proof gas pipeline of noise reduction.
Background technology
The transport of natural gas is mainly based on pipeline transportation.Due to the variation of pipe diameter, due to the change of external environment
Change, the gas flow rate in gas pipeline can change, to generate impact to tube wall.Therefore, it is needed into the gas pipeline in building
Some are carried out to eliminate the noise and sound insulation processing.The method mainly used at present is that the outside of gas pipeline is provided with carbon steel material
Casing or multilayer sleeve.But since pipeline enters, changing greatly for caliber and pipeline after building is more, and the prior art uses
Scheme can not easily reach to the gas pipeline comprehensively etch-proof purpose of noise reduction.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of etch-proof gas pipeline of noise reduction, in order to caliber and
Pipeline changes the protection of gas pipeline greatly, improves the soundproof effect of gas pipeline.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：
The outside of a kind of etch-proof gas pipeline of noise reduction, the gas pipeline is cased with bellows, the gas pipeline
Between outer wall and the bellows be filled with silencing cotton, the gas pipeline from the inside to the outside be respectively plastic lining, metal layer and
Anticorrosive paint layer.
Preferably, the silencing cotton uses polyester fiber fire proofing material.
Preferably, the anticorrosive paint layer is polyethylene coating, epoxy coating or polyamide coating layer.
Preferably, the bellows is metal bellows.
Compared with prior art, the beneficial effects of the utility model are：Bellows is conducive to adapt to caliber or pipeline
Change big gas pipeline, reduces the cost of casing.Moreover, silencing cotton closely can be fixed on gas pipeline by bellows
The soundproof effect of gas pipeline is improved in outside.
Description of the drawings
Some specific realities of the utility model are described in detail by way of example rather than limitation with reference to the accompanying drawings hereinafter
Apply example.Identical reference numeral denotes same or similar component or part in attached drawing.It should be appreciated by those skilled in the art that
The drawings are not necessarily drawn to scale.In attached drawing：
Fig. 1 is a kind of schematic diagram of the etch-proof gas pipeline of noise reduction of the utility model.
Meaning in figure represented by each symbol is as follows：
1- inner walls, 2- outer walls, 3- silencing cottons, 4- bellowss.
Specific implementation mode
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As shown in Figure 1, the etch-proof gas pipeline of the utility model noise reduction, includes mainly inner wall 1 and outer wall 2.Gas Pipe
Road is introduced into from gas company in building, under construction according to the change of the caliber and pipeline of the design gas pipeline of gas supply demand
Change larger.In order to protect gas pipeline, bellows 4 is cased with outside it.Bellows 4 can be conducive to adapt to the change of gas pipeline
Change.In the present embodiment, the bellows 4 uses metal bellows, shakes impact force to reduce the air-flow that gas pipeline is subject to,
And buffering is from external impact force.
In the present invention, the gas pipeline is respectively plastic lining, metal layer and anticorrosive paint layer from the inside to the outside.
Using PE plastic layers, either inner wall 1 is coated with plastic coating or resinous coat to the inner wall 1 of gas pipeline.Plastic coating is a kind of
Resistant material can be effectively prevented from corrosion of the combustion gas to inner wall 1.The outer wall 2 of gas pipeline is metal layer.Wherein, golden
Belong to the plastic lining setting that layer is close to inner wall 1.The outside of the outer wall 2 of gas pipeline is coated with anticorrosive paint layer, outer to prevent
The corrosion of portion's ambient moisture.Wherein, the anticorrosive paint layer can be that polyethylene coating, epoxy coating or polyamide apply
Layer.
Silencing cotton 3 is filled between the outer wall 2 and the bellows 4 of the gas pipeline.Silencing cotton 3 is by bellows 4
Wave structure be pressed tightly against on gas pipeline, to effectively adapt to the variation of gas pipeline caliber or pipeline, comprehensively
Gas pipeline is wrapped up, the soundproof effect of gas pipeline is improved.Wherein, the silencing cotton 3 uses polyester fiber fire proofing material, tool
There is outstanding fire-retardant fireproof function, fire-retardant function is also assured while sound-insulation.
The embodiment of the utility model is explained in detail above in association with attached drawing, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the scope of protection of the utility model.
