Background technique
Along with the high speed development of national economic development and the gradual perfection of urban infrastructure, the demand of various types of steel is increasing, also will adapt to its technical requirements accordingly to fastener for connection parts thereupon.At present, in the prior art, between steel pipe, employing is threaded or welds to connect mostly.Be threaded fast easy to loading and unloading, but have certain precision to the processing request of steel pipe, and steel pipe jointing be corroded after cannot remedy, can only pipeline section be changed.If welding do not have correct technique to instruct, do not have masterful technique to there will be the weld defects such as lack of penetration, crackle, slag inclusion, pore undercut, affect pipeline section working life.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of steel pipe connection structure with plastic joint, this steel pipe connection structure can connect two sections of steel pipes closely, install or change convenient and swift, economical and practical, and welding is also lower to the technical requirements of installation personnel relatively.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is:
A kind of steel pipe connection structure, comprise steel pipe body, outer plastic joint, interior plastic joint and interfacial adhesion oxidant layer, the two ends of described steel pipe body, described outer plastic joint is equipped with in one end, the other end is equipped with described interior plastic joint, described outer plastic joint is provided with annular groove with steel pipe body joint, steel pipe body injects in annular groove, and between steel pipe body and groove, be provided with interfacial adhesion oxidant layer, steel pipe body and outer plastic joint are linked together more closely, the other end of described outer plastic joint is provided with internal thread, identical with described outer plastic joint with the shape of steel pipe body joint on described interior plastic joint, body and groove joint are also provided with interfacial adhesion oxidant layer, the other end of described interior plastic joint is provided with outside thread, together with adjacent two steel pipes to be screwed up with the screw thread on interior plastic joint by described outer plastic joint, thread interface is provided with interfacial adhesion oxidant layer equally.
Further, the outer plastic joint in described steel pipe connection structure and interior plastic joint are all formed by engineering plastics injection molding.
Further, the outer plastic joint in described steel pipe connection structure and the screw thread on interior plastic joint are V thread screw.
Further, the length of position on steel pipe longitudinal section that the outer plastic joint in described steel pipe connection structure and the groove on interior plastic joint contact with steel pipe body can not be less than steel pipe inner wall diameter.
The invention has the beneficial effects as follows:
This steel pipe connection structure provided by the invention, comprises steel pipe body, outer plastic joint, interior plastic joint and interfacial adhesion oxidant layer.The two ends of steel pipe body are equipped with outer plastic joint and interior plastic joint respectively, outer plastic joint and interior plastic joint are provided with annular groove with steel pipe body joint, steel pipe body inserts in the groove of described outer plastic joint or interior plastic joint, interfacial adhesion oxidant layer is provided with between groove and steel pipe, therefore steel pipe can be closely linked with inside and outside plastic joint, and effectively can prevent the seepage of managing interior circulating liquid.Together with adjacent two sections of steel pipes are screwed up by the screw thread between outer plastic joint with interior plastic joint, quick construction is convenient.Cannot remedy after traditional threaded steel pipe jointing corrosion, can only change pipeline section, take time and effort, after steel pipe is connected by described linkage structure, jointing is not easily corroded, then also simple and convenient to change the interface damaged.
