Abstract
The utility model relates to a corrosion-resistant bellows, comprising a bellow. The utility model is characterized in that the bellow is coated with a protective layer made of nickel alloy plates, and the protective layer and the inner bellow form a multi-ply bellow. The utility model has the advantages of high flexibility, heat resistance, high pressure bearing capability, high anti-corrosion capability, long service life of compensators, simple structure, and easy manufacturing.
Description
The utility model belongs to a kind of bellows that is used for heating power pipeline flexible compensation, the erosion-resisting bellows of particularly a kind of high-performance.
With the bellows is the compensator of flexible compensation element, little with its volume, flexible good, install, transportation is easy, and benefit become heat distribution pipeline lay in indispensable important pipe fitting, though existing bellows has heat-resisting, withstand voltage, good springiness, and certain antiseptic property, but for outdoor rainwater, trench humid air and the underground long-term erosion that contains sour water, it is not enough that its antiseptic power just shows, make bellows resist interior the pressure and compensate function because of corrosion loses, reduced the life-span of compensator; And bellows is brushed the anti-corrosion measure of anticorrosive paint outward, causes brushing uneven because of brushing inconvenience again, and the defective of coating chance hot cracking, and makes its anticorrosion effect that do not reach.
The purpose of this utility model provides a kind of anti-rotten bellows, not only keeps its good springiness and heat-resisting function, also has the efficient corrosion resisting function simultaneously, and is simple in structure, easy processing.
The purpose of this utility model is achieved in that it comprises bellows, and its technological scheme main points are: the sheath of coated nickel alloy plate outside bellows, its bellows inner with it constitutes multiply bellows.
The utility model has the advantages that: flexible good, heat-resisting, the pressure-bearing height has high anti-corrosion capability, improves the working life of compensator, and simple in structure, easy processing.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
See Fig. 1, concrete structure is as follows: the outside of common heat-resisting alloy steel plate bellows 2, and coated anti-rotten sheath 1 adopts nickeliferous 40% the nickel alloy plate that is higher than, and it and bellows 2 constitute multiply bellows jointly.
