Abstract
The invention provides a pipe joint. The pipe joint comprises a metal outer pipe and a plastic inner pipe, wherein ribs distributed on the circumferential direction of the plastic inner pipe are arranged in the middle of the outer surface of the plastic inner pipe, the plastic inner pipe is sleeved in the metal outer pipe, internal threads are arranged at two ends of the metal outer pipe, and a rubber pad is arranged on the plastic inner pipe. The pipe joint has the advantages of being high in intensity, resistant to corrosion, and low in cost.
Description
Technical field
The present invention relates to a kind of pipe joint.
Background technique
Existing connecting tube is generally the pipelines such as aluminium-plastic pipe, PEX pipe, is generally die cast metal or injection molded.In metal joint, copper sleeve is the most general, but copper price is higher, particularly in large-caliber pipe fittings, uses, and cost is high.Intensity and the serviceability of plastic joint are poor.
Summary of the invention
The object of this invention is to provide a kind of pipe joint, cost is low, and intensity is high, good seal performance.
Technological scheme of the present invention is: a kind of pipe joint, comprise metal outer pipe and plastic inner pipe, and the middle part of plastic inner pipe outer surface is provided with circumferential fin, and plastic inner pipe is set in metal outer pipe, and the two ends of metal outer pipe are provided with internal thread.
Further, on described plastic inner pipe, rubber pad is set, described rubber pad is stuck in the both sides of fin.
Advantage and good effect that the present invention has are: intensity is high, corrosion-resistant, and cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of plastic inner pipe.
In figure:
1, metal outer pipe 2, plastic inner pipe 3, fin
4, rubber pad
Embodiment
Below in conjunction with accompanying drawing, the present invention is elaborated.
As shown in Figure 1, 2, the present invention is a kind of pipe joint, comprises metal outer pipe 1 and plastic inner pipe 2, and the middle part of plastic inner pipe 2 outer surfaces is provided with circumferential fin 3, and plastic inner pipe 2 is set in metal outer pipe 1, and the two ends of metal outer pipe 1 are provided with internal thread.
Further, on described plastic inner pipe 2, rubber pad 4 is set, described rubber pad 4 is stuck in the both sides of fin 3.
During connection, metal outer pipe 1 is connected with pipeline outer surface by screw thread, and plastic inner pipe 2 is inserted in connecting pipeline.The rubber pad 4 of fin 3 both sides can make jointing keep sealing.Metal outer pipe 1 can guarantee that joint has very high intensity, and plastic inner pipe 2 has corrosion resistance, has guaranteed the working life of metal outer pipe 1.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the present patent application scope and improvement etc., within all should still belonging to patent covering scope of the present invention.
Claims (2)
1. a pipe joint, is characterized in that: comprise metal outer pipe and plastic inner pipe, the middle part of plastic inner pipe outer surface is provided with circumferential fin, and plastic inner pipe is set in metal outer pipe, and the two ends of metal outer pipe are provided with internal thread.
2. pipe joint according to claim 1, is characterized in that: rubber pad is set on plastic inner pipe, and described rubber pad is stuck in the both sides of fin.
