Abstract
The invention discloses an integrally formed wear-resistant metal corrugated pipe expansion joint. The integrally formed wear-resistant metal corrugated pipe expansion joint comprises two connecting pipes and a corrugated pipe connected between the connecting pipes, wherein first ceramic layers are also arranged on the inner wall surfaces of the connecting pipes, a lining pipe is also arranged in the corrugated pipe, the two ends of the lining pipe respectively extend into the connecting pipes, and a second ceramic layer is arranged on the inner wall surface of the lining pipe; the first ceramic layers are integrally clung on the inner wall surfaces of the connecting pipes in a chemically sintering way, and the second ceramic layer is also integrally clung on the inner wall surface of the lining pipe in a chemically sintering way; and gaps are formed between the lining pipe and one connecting pipe and between the lining pipe and another connecting pipe, and the edges of the two ends of the lining pipe are hermetically connected with the first ceramic layers and the second ceramic layer respectively. The integrally formed wear-resistant metal corrugated pipe expansion joint has the benefits as follows: the ceramic layers form a whole body with the smooth surface, so that gaps between ceramic wafers are avoided; the wear resistance of the expansion joint is further improved; and the service life of the expansion joint is prolonged.
Description
Technical field
The present invention relates to a kind of expansion joint, relate in particular to a kind of one-body molded antifriction metal (AFM) bellows expansion joint.
Background technique
The additional stress that expansion joint causes because of temperature difference and mechanical vibration for compensation, and be arranged on a kind of flexible structure on container shell or the pipeline.Because it is as a kind of elastic compensating element that can freely stretch, advantages such as reliable operation, functional, compact structure have been widely used in departments such as chemical industry, metallurgy, nuclear energy.Expansion joint also is slip joint traditionally; Or corrugated expansion joint; Be that effective dilatation in order to the elastic element that utilizes corrugated expansion joint absorbs pipeline, conduit or the container a kind of compensation device by former thereby the dimensional changes that produces such as expand with heat and contract with cold, belong to a kind of compensating element.Can be to axially, laterally and the absorption of angular displacement, be used for adding thermal walking, mechanical displacement absorbed oscillation, reduce noise etc. in pipeline, equipment and system.The additional stress that expansion joint causes because of temperature difference and mechanical vibration for compensation, and be arranged on a kind of flexible structure on container shell or the pipeline.Because it is as a kind of elastic compensating element that can freely stretch, advantages such as reliable operation, functional, compact structure have been widely used in departments such as chemical industry, metallurgy, nuclear energy.The expansion joint that on container, adopts has various ways, with regard to the shape of ripple, uses the most extensively with the U-shaped expansion joint, secondly also has Ω shape and C shape etc.And the expansion joint that on pipeline, adopts has universal, pressure balance type, hinge type and universal joint formula etc. again with regard to structure compensation.Bellows expansion joint is a kind of expansion joint of processing with metal bellows.It can be flexible along axial direction, also allows a small amount of crooked.But bellows expansion joint is in use, can easy abrasion, and especially under the condition of high temperature, the process of regular experience rising-heat contracting-cold, it is especially serious to wear and tear.This has had a strong impact on the life-span of expansion joint.
Summary of the invention
Technical problem to be solved by this invention is the deficiency to above-mentioned existing technology, and a kind of expanding with heat and contract with cold of can bearing is provided, and nonabradable one-body molded antifriction metal (AFM) bellows expansion joint.
For solving the problems of the technologies described above; The technological scheme that the present invention takes is: this one-body molded antifriction metal (AFM) bellows expansion joint; Comprise two bellowss of taking over and being connected between the adapter, on the internal face of taking over, also be provided with first ceramic layer, in bellows, also be provided with internal lining pipe; The two ends of internal lining pipe are stretched into respectively in the adapter, and the internal face of said internal lining pipe is provided with second ceramic layer; It is characterized in that: said first ceramic layer adopts chemically sintered mode to be close to the nozzle inner wall face one-body moldedly, and said second ceramic layer also adopts chemically sintered mode to be close to the internal lining pipe internal face one-body moldedly.
As the further improved technological scheme of the present invention, leave the slit between said internal lining pipe and the adapter, the edges at two ends of internal lining pipe is tightly connected with first ceramic layer and second ceramic layer respectively.
The sheet material that adapter of the present invention and internal lining pipe adopt is common Q235 steel plate; Add wear-resisting ceramic layer then, ceramic layer is one-body molded through chemically sintered mode, thereby ceramic layer is as a whole; Its smooth surface; So just avoid the slit between the individual ceramic plate, further improved the wear resistance of the one-body molded antifriction metal (AFM) bellows expansion joint of the present invention, prolonged the working life of product.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the local enlarged diagram at A place among Fig. 1.
Be described further below in conjunction with the accompanying drawing specific embodiments of the invention.
Embodiment
Referring to Fig. 1; This one-body molded antifriction metal (AFM) bellows expansion joint; Comprise two adapters 1 and be connected the bellows of taking between 12, on the internal face of adapter 1, also be provided with first ceramic layer 3, in bellows 2, also be provided with internal lining pipe 4; The two ends of internal lining pipe 4 are stretched into respectively and are taken in 1, and 4 internal faces of said internal lining pipe are provided with second ceramic layer 5; Said first ceramic layer 3 adopts chemically sintered mode to be close to one-body moldedly and takes over 1 internal face, and said second ceramic layer 5 also adopts chemically sintered mode to be close to internal lining pipe 4 internal faces one-body moldedly.Said internal lining pipe 4 and take over 1 between leave the slit, the edges at two ends of internal lining pipe 4 is tightly connected with first ceramic layer 3 and second ceramic layer 5 respectively.First ceramic layer 3 and second ceramic layer 5 are all one-body molded through chemically sintered mode.That adopts in the present embodiment is chemically sintered for existing technology, and promptly common ceramic sintering process gets final product.First ceramic layer 3 and second ceramic layer 5 are an independently integral body thus.Perhaps first ceramic layer 3 links to each other with second ceramic layer 5, becomes a unified integral body.The smooth surface of such first ceramic layer 3 and second ceramic layer 5 has just been avoided the slit between each ceramic plate, has further improved the wear resistance of the one-body molded antifriction metal (AFM) bellows expansion joint of the present invention, has prolonged the working life of product.
