Problems solved by technology

[0003] For example, the utility model patent application (application number: 201520811254.1) discloses a plastic water supply pipe threaded inner pipe joint, which includes a hot-melt connection body and a threaded connection body. part, the threaded part is located inside, the inner wall of the threaded part has an internal thread, the other end of the threaded connection body is sleeved on the connection part, and the connection part is located in the insertion groove, and the threaded connection body is made of engineering plastics , the main body of the hot-melt connection is made of hot-melt plastic. Since the inner peripheral surface of the threaded main body and the connecting part is mated with a smooth surface, there is no connecting part between the two to strengthen the connection strength. Applicable, but when the pipe joint is used in the cold and hot water circulation condition, the accumulation change of the water temperature will cause the hardness of the hot-melt connection body to weaken, and eventually cause the pipe joint to burst

Embodiment 1

[0033] like figure 1 As shown, a plastic water supply pipe joint, the pipe joint is a threaded elbow, including a hot-melt connection main body 1 and a threaded connection main body 2, the threaded connection main body 2 is made of engineering plastics, has high mechanical properties and resistance to high, Low temperature performance, good dimensional stability, there is an internal thread on the inner peripheral wall of the threaded connection body 2, which is used for threaded connection with the water supply pipe, that is, the pipe joint is a threaded internal elbow, and the hot-melt connection body 1 is made of hot-melt plastic It is made of PP-R or PE, which has good creep resistance at relatively high temperatures. One end has a connecting part 14 for welding and fixing with the water supply pipe. The hardness of the threaded connection body 2 is greater than that of the hot-melt connection body 1 The other port of the hot-melt connection body 1 has a cylindrical connec...

Embodiment 2

[0037] The structure of the plastic water supply pipe joint is basically the same as that of the embodiment, the difference is that Figure 4 As shown, the cross-section of the pullout strip 111 is triangular.

Embodiment 3

[0039] The structure of the plastic water supply pipe joint is basically the same as that of the embodiment, the difference is that Figure 5 As shown, the cross-section of the anti-pull bar 111 is rectangular.

Abstract

The invention provides a plastic pipe joint of a water supply pipeline, belongs to the technical field of water pipe components, and solves the problem that an existing pipe joint is liable to burst under the working condition of hot and cold water circulation. The plastic pipe joint of the water supply pipeline comprises a hot-melting connection main body and a thread connection main body, wherein the hot-melting connection main body is provided with a connection part; the thread connection main body is connected to the inner circumferential surface and the outer circumferential surface of the connection part in a hot-melting manner; an anti-torsion lug is arranged on the outer wall of the connection part; the inner circumferential surface of the connection part is configured to be a conical surface; an anti-pulling bar is arranged on the inner circumferential surface of the connection part; a buckling groove is formed in the outer circumferential surface of the hot-melting connection main body; the port of the thread connection main body is provided with an anti-pulling flange; the anti-pulling flange is buckled in the buckling groove; and the anti-pulling flange is located at the inner end of the anti-pulling bar. The plastic pipe joint of the water supply pipeline has high anti-pulling and anti-torsion performance under the working condition of high-temperature and low-temperature water circulation, and a long service life.

Description

technical field [0001] The invention belongs to the technical field of water pipe components and relates to a plastic water supply pipe joint. Background technique [0002] A pipe joint is a connecting fitting between a pipe and a pipe. It is a detachable connection between the fitting and the pipe. It plays an indispensable role in the pipe fitting. It is one of the main components of the pipe. The type of pipe joint There are many and widely used, among which the application is more concentrated in the connection of water supply pipes. The water supply pipes need to transport water to a height of tens of meters or even higher, so the requirements for the pressure bearing and sealing performance of pipe joints are relatively high. [0003] For example, the utility model patent application (application number: 201520811254.1) discloses a plastic water supply pipe threaded inner pipe joint, which includes a hot-melt connection body and a threaded connection body. part, the t...
