Abstract
The utility model provides a kind of metal bellows, it adopts technology material to make, described bellows comprises three-decker: outside corrugated metal pipe, the corrugated plastic hose layer at middle part and the straight cylinder type layer of PVC of inside, described corrugated plastic hose is connected with straight cylinder type layer of PVC compound blow, described corrugated metal pipe adopts stainless steel to make, and its outer wall is provided with zinc coat.The utility model high insulating effect, corrosion resistance is strong, sound construction long service life.
Description
Technical field
The utility model relates to a kind of metal bellows.
Background technique
Plastic film capicitor is mainly used in underground preburied pipeline.Be in process of assembling, indoor underground needs pre-buried hot water pipeline, general identical with cold water pipes material, is all the single-wall structure pipeline be made up of PVC or polyethylene, is therefore unfavorable for hot water thermal insulating, usually also has Insulation, but need extra construction sequence; In addition, existing bellows insufficient strength, working life is short.
Summary of the invention
In order to solve the problem that bellows in prior art is unfavorable for being incubated, the utility model provides a kind of high insulating effect, the bellows that rotproofness is good.
To achieve these goals, the utility model provides following technological scheme:
A kind of metal bellows, it adopts technology material to make, described bellows comprises three-decker: outside corrugated metal pipe, the corrugated plastic hose layer at middle part and the straight cylinder type layer of PVC of inside, described corrugated plastic hose is connected with straight cylinder type layer of PVC compound blow, described corrugated metal pipe adopts stainless steel to make, and its outer wall is provided with zinc coat.
The beneficial effect that the utility model brings is: high insulating effect, and corrosion resistance is strong, sound construction long service life.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
As shown in Figure 1, a kind of metal bellows, it adopts technology material to make, described bellows comprises three-decker: outside corrugated metal pipe 1, the corrugated plastic hose layer 2 at middle part and the straight cylinder type layer of PVC 3 of inside, described corrugated plastic hose is connected with straight cylinder type layer of PVC compound blow, described corrugated metal pipe adopts stainless steel to make, and its outer wall is provided with zinc coat 4.
The advantage that embodiment described in the utility model has is: high insulating effect, and corrosion resistance is strong, sound construction long service life.
The above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the utility model; the change can expected without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
