Abstract

The utility model relates to an anticorrosion pipe fitting, including steel pipe, joint and a pair of mounting, be provided with the plastic tubing of outer fringe and steel pipe inner edge contact in the steel pipe, plastic tubing both ends inner wall all is equipped with annular step, and is equipped with the screw thread on the bench wall that annular step is close to the plastic tubing port, and a pair of mounting is located two ports of plastic tubing respectively, and the mounting is connected a whole that forms by the equal drum of external diameter size inequality of two internal diameters. The utility model discloses simple structure, convenient to use can change the inlayer plastic tubing, convenient maintenance after long-term the use. In addition, the wear-resisting anticorrosive coating outside the steel pipe can prevent that the steel pipe is outside by the corruption, and the setting of inlayer plastic tubing can prevent that the steel pipe is inside by the corruption.

Description

Anti-corrosion pipe fitting
Technical Field
The utility model relates to a pipe fitting production technical field especially relates to an anticorrosion pipe fitting.
Background
The pipeline, especially the pipeline that transports corrosive solution, the life that generally requires is all very long, but traditional pipeline does not have this aspect of design, only uses the iron pipe as the pipeline, and the consequence that such setting brings is, often still does not reach the life of pipeline, and the inside and outside of pipeline has all been corroded, and the outside corrosion of pipeline can influence the intensity of pipeline, and the inside corrosion of pipeline not only influences pipeline intensity, still can reduce the life of water pipe.
Disclosure of Invention
The utility model aims at solving the defects of the prior art and providing an anti-corrosion pipe fitting.
The utility model discloses a realize above-mentioned purpose, adopt following technical scheme: an anti-corrosion pipe fitting comprises a steel pipe, a joint and a pair of fixing parts, and is characterized in that a plastic pipe with an outer edge contacting with the inner edge of the steel pipe is arranged in the steel pipe, annular steps are arranged on the inner walls of two ends of the plastic pipe, threads are arranged on the table walls of the annular steps close to the end opening of the plastic pipe, the pair of fixing parts are respectively arranged at two end openings of the plastic pipe, the fixing parts are a whole formed by connecting two cylinders with equal inner diameters and different outer diameters, the inner diameters of the two cylinders with different outer diameters are equal to the inner diameter of the plastic pipe, threads matched with the threads of the end opening of the plastic pipe are arranged on the outer side wall of the cylinder with smaller outer diameter of the fixing part, a support ring is arranged on one side of the cylinder with larger outer diameter close to the cylinder with smaller outer diameter, the inner, the both ends of joint all are equipped with the internal thread, and the one end and the steel pipe threaded connection of joint, and the steel pipe outside is equipped with wear-resisting anticorrosive coating.
The fixing piece is made of polyethylene.
The sealing ring is an O-shaped sealing ring.
The wear-resistant anticorrosive layer is a mixed coating of phenolic epoxy resin and bisphenol A epoxy resin.
The thickness of the wear-resistant anticorrosive layer is 3 mm.
The utility model has the advantages that: the utility model discloses simple structure, convenient to use can change the inlayer plastic tubing, convenient maintenance after long-term the use. In addition, the wear-resisting anticorrosive coating outside the steel pipe can prevent that the steel pipe is outside by the corruption, and the setting of inlayer plastic tubing can prevent that the steel pipe is inside by the corruption.
Drawings
Fig. 1 is a schematic structural view of the present invention;
in the figure: 1-a steel pipe; 2-plastic pipe; 3-a fixing piece; 4-a support ring; 5-sealing ring; 6-a linker;
the following detailed description will be made in conjunction with embodiments of the present invention with reference to the accompanying drawings.
Detailed Description
The invention will be further explained with reference to the following figures and examples:
as shown in figure 1, the anti-corrosion pipe fitting comprises a steel pipe 1, a joint 6 and a pair of fixing pieces 3, and is characterized in that a plastic pipe 2 with the outer edge contacting with the inner edge of the steel pipe 1 is arranged in the steel pipe 1, the inner walls of two ends of the plastic pipe 2 are respectively provided with an annular step, the annular step is provided with a thread on the table wall close to the port of the plastic pipe 2, the pair of fixing pieces 3 are respectively positioned at two ports of the plastic pipe 2, the fixing pieces 3 are a whole formed by connecting two cylinders with equal inner diameters and different outer diameters, the inner diameters of the two cylinders with different outer diameters are equal to the inner diameter of the plastic pipe 2, the outer side wall of the cylinder with smaller outer diameter of the fixing piece 3 is provided with a thread matched with the thread of the port of the plastic pipe 2, one side of the cylinder with larger outer diameter close to the cylinder with, the great drum of external diameter all is equipped with the external screw thread on the outer wall of 1 port of steel pipe, and the both ends that connect 6 all are equipped with the internal thread, and the one end and the 1 threaded connection of steel pipe that connect 6, and the 1 outside of steel pipe is equipped with wear-resisting anticorrosive coating.
The fixing member 3 is made of polyethylene.
The sealing ring 5 is an O-shaped sealing ring.
The wear-resistant anticorrosive layer is a mixed coating of phenolic epoxy resin and bisphenol A epoxy resin.
The thickness of the wear-resistant anticorrosive layer is 3 mm.
The utility model discloses the during operation, in wearing plastic tubing 2 to steel pipe 1, install sealing washer 5 on the support ring 4 of mounting 3 again, with two 3 threaded connection of mounting on plastic tubing 2 to fix plastic tubing 2 on steel pipe 1, be connected the one end of steel pipe 1 with joint 6, make steel pipe 1 be connected with the drain pipe through joint 6 at last, accomplish the installation. When plastic tubing 2 is changed to needs, will connect 6 and twist off from steel pipe 1, twist off mounting 3 from plastic tubing 2 again, change old plastic tubing 2 with new plastic tubing 2, the utility model discloses simple structure, convenient to use can change inlayer plastic tubing 2, convenient maintenance after long-term the use. In addition, the wear-resistant anticorrosive layer outside the steel pipe 1 can prevent the steel pipe 1 from being corroded, and the inner plastic pipe 2 can prevent the steel pipe 1 from being corroded. Therefore, the corrosive solution does not contact the inner wall of the steel pipe 1 to corrode the steel pipe 1, increasing the service life thereof.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above embodiments, and various improvements made by the method concept and technical solution of the present invention or directly applied to other occasions without improvement are all within the protection scope of the present invention.
