Problems solved by technology

[0002] In the prior art, due to the high inertia of high-density polyethylene pipes, it is difficult to connect multiple sections of pipes through adhesives. However, as the height of high-rise buildings continues to increase, in the process of producing high-density polyethylene pipes, only It can be produced in sections, and then when the high-density polyethylene pipes are applied to high-rise buildings, the high-density polyethylene pipes produced in sections are connected in series for use. When the high-density polyethylene pipes produced in the first section are connected in series, because the joints are difficult to glue and seal, it is easy to cause poor connection stability or pipeline leakage problems. If things go on like this, the overall construction quality of high-rise buildings will be threatened

Embodiment 1

[0042] See attached figure 1 In the pipe provided by Embodiment 1 of the present invention, at the end of the pipe, at least one first groove or protrusion along the circumference of the pipe is provided along the inner or outer wall of the pipe. In this embodiment, the pipe 1 is provided with at least one (in this embodiment, two) grooves or protrusions 3a of the first type along the circumference of the pipe at least one (in this embodiment, two) grooves or protrusions 3a on the outer wall of the socket. The socket is provided with at least one (in this embodiment, two) first-type protrusions or grooves 3b on the inner wall, so that the grooves or protrusions 3a and the protrusions or grooves 3b form a one-to-one correspondence relation. Among them, in order to make the plugging between the pipe 1 and the pipe 2 more convenient, it is also possible to process a diameter-expanding convex ring at the socket 5 of the pipe 2 in the process of processing the pipe 2. At this time...

Embodiment 2

[0046] See attached figure 2 And attached image 3 The pipe joint provided by the second embodiment of the present invention is cylindrical, and the two axial ends of the pipe joint are respectively provided with a second type of groove or protrusion, and the shape of the second type of groove or protrusion is the same as that of the first type of concave Match the shape of the groove or protrusion. In this case, it is only necessary to make another pipe joint 6, so that the sockets 7a, 7b at both ends of the pipe joint 6 are respectively inserted into the pipe materials 1a, 1b to be inserted, and then the pipe materials 1a, 1b to be inserted can be realized. The connection between 1b is convenient for insertion and connection, and the manufacturing cost is low. Wherein the overall outer diameter of the pipe joint 6 may be uniform, or for the convenience of treating the connection between the inserted pipes 1a, 1b, a diameter-expanding protruding ring 7a and 7b may be proce...

Embodiment 3

[0048] See attached figure 1 The first composite pipe material provided by Embodiment 3 of the present invention includes multiple sections of the pipe material provided by the present invention, and each section of pipe material is connected in series through the first type of groove or protrusion. In this embodiment, the pipe 1 is provided with at least one (in this embodiment, two) grooves or protrusions 3a of the first type along the circumference of the pipe at least one (in this embodiment, two) grooves or protrusions 3a on the outer wall of the socket. The socket is provided with at least one (in this embodiment, two) first-type protrusions or grooves 3b on the inner wall, so that the grooves or protrusions 3a and the protrusions or grooves 3b form a one-to-one correspondence relation. Among them, in order to make the plugging between the pipe 1 and the pipe 2 more convenient, it is also possible to process a diameter-expanding convex ring at the socket 5 of the pipe 2...

Abstract

The invention discloses a pipe, a pipe joint, a combined pipe, a sealing piece and a connecting method of the combined pipe, and belongs to the technical field of pipe connection. At least one first-type groove or bulge in the circumferential direction of the pipe is arranged at the end of the pipe along the inner wall or the outer wall of the pipe. The pipe joint is cylindrical, second-type grooves or bulges are respectively arranged on the two axial ends of the pipe joint, and the shape of the second-type grooves or bulges is matched with the shape of the first-type groove or bulge. All sections of pipes of the combined pipe are connected in series in an embedded mode through the first-type groove or bulge. Or the combined pipe is formed by connecting the pipe and the pipe joint in series at an interval in an embedded mode by means of the first-type groove or bulge arranged on the pipe and the second-type grooves or bulges arranged on the pipe joint. The sealing element can form sealing at a to-be-sealed part. According to the connecting method of the combined pipe, the multiple sections of pipes or the multiple sections of pipes and the pipe joints can be connected together in asealed mode, so that the pipe connection stability can be guaranteed, and the leakage possibility is reduced.

Description

technical field [0001] The invention relates to the technical field of pipe connection, in particular to pipes, pipe joints, composite pipes, seals and a method for connecting composite pipes. Background technique [0002] In the prior art, due to the high inertia of high-density polyethylene pipes, it is difficult to connect multiple sections of pipes through adhesives. However, with the continuous increase in the height of high-rise buildings, in the production process of high-density polyethylene pipes, only It can be produced in sections, and then when the high-density polyethylene pipes are applied to high-rise buildings, the high-density polyethylene pipes produced in sections are connected in series for use. When the high-density polyethylene pipes produced in the section are connected in series, because the joints are difficult to glue and seal, it is easy to cause poor connection stability or pipeline leakage problems. If things go on like this, the overall construc...
