Description
Technical field
The utility model relates to pipe joint structure and improves field, particularly a kind of combined anti-wear spigot and socket type steel pipe joint.
Background technique
The pipe joint of prior art, especially plastic-coated-type pipe joint, it is in use, the plastic-coated inwall of bellmouth is easy to and socket generation frictional impact, and the inwall of bellmouth produces wearing and tearing, and coating even can be caused to be destroyed, and then affect its sealing, and shorten the working life of joint greatly.
Model utility content
The purpose of this utility model is to solve the problem, and devises a kind of combined anti-wear spigot and socket type steel pipe joint.
Realizing above-mentioned purpose the technical solution of the utility model is, a kind of combined anti-wear spigot and socket type steel pipe joint, comprise socket 7 and bellmouth 8, described socket inserts in bellmouth, described socket 7 is provided with differential 3, and described differential is fixedly connected with bellmouth edge with nut 1 by bolt 2, and the internal surface of described bellmouth is provided with embedded groove, described embedded groove has been embedded in cushion rubber 4, cage ring 5 and bracing ring 6, and described cushion rubber and bracing ring are combined and formed interference fit with the jack part inserting bellmouth.
Described embedded groove is conical structure.
The cross section of described cushion rubber 4 sidewall is wedge-shaped structure.
The cross section of described cage ring 5 sidewall is wedge-shaped structure.
The cross section of described bracing ring 6 sidewall is semicircle.
Described bracing ring 6 is positioned at embedded groove inside, and described cushion rubber 4 is positioned at embedded groove port, and described cage ring 5 is between bracing ring and cushion rubber.
The cushion rubber of embedded groove port is pushed down in the bottom of described differential 3.
The combined anti-wear spigot and socket type steel pipe joint utilizing the technical solution of the utility model to make, the inwall of faucet part adopts rolling technology to process embedded groove, is arranged in embedded groove by cushion rubber, cage ring and bracing ring, inserts socket and can complete sealing; This apparatus structure is simple, easy for installation, be connected firmly, can not destroy coating layer in installation process.
