AI Technical Summary
When PE pipes are transferred after cutting, the flatness of the cut surface is high, and the thickness of the pipe wall in the hot-soluble part is easily affected, resulting in leakage problems. When flexing the pipe, traditional joints are inconvenient to use.
A PE pipe with a connecting pipe structure is designed, including a connecting pipe, a conductive pipe, an outer clamping ring, an inner supporting ring and a seal. The pipe incision is clamped by the combined "U-shaped" structure of the outer clamping ring and the inner supporting ring. The seal adheres closely to the pipe wall under deformation external force to achieve rapid transfer, and is used instead of the elbow through a corrugated transfer pipe.
It reduces the flatness requirements of the cut surface during pipeline transfer, reduces the risk of leakage, and simplifies the use of elbow joints through the corrugated structure transfer pipe, improving the speed and stability of pipeline connections.

[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.
[0022] like Figure 1-3 As shown, the utility model provides a PE pipe with a pipe structure, comprising a pipe 1, a transfer pipe 2 is provided on one side of the pipe 1, and a conducting pipe 3 is formed at both ends of the transfer pipe 2;
[0023] The sealing mechanism comprises an outer clamping ring 41 and an inner supporting ring 42 installed on the conducting pipe 3, the outer clamping ring 41 and the inner supporting ring 42 clamp the pipe 1, the outer clamping ring 41 is attached to the outer wall of the pipe 1, a gap is left between the inner supporting ring 42 and the pipe 1, and a sealing member 43 attached to the inner wall of the pipe 1 is placed in the gap;
[0024] The locking mechanism comprises a bolt seat 51 arranged on the outer periphery of the outer clamp ring 41 , and a limit bolt 52 attached to the outer wall of the pipeline 1 is threadedly connected in a bolt hole formed in the bolt seat 51 .
[0025] It should be noted that: the end faces of the conducting tube 3 attached to the inner support ring 42 have the same inner diameter, and the combination of the inner support ring 42 and the conducting tube 3 as a temporary transmission channel for the transition section of the pipeline 1. The same inner diameter ensures stable medium transmission, and the end face of the conducting tube 3 facing the transition tube 2 is an inclined structure. The purpose of the inclined structure is to ensure stable medium transmission in the transition tube 2.
[0026] In this embodiment, when the pipeline is switched, the combination of the outer clamping ring 41 and the inner supporting ring 42 is an overall "U-shaped" structure. The cut end face of the pipeline 1 is facing the clamping gap between the outer clamping ring 41 and the inner supporting ring 42, and the seal 43 is placed on the inner supporting ring 42. Subsequently, the outer clamping ring 41 and the inner clamping ring 42 are pushed toward the cut of the pipeline 1. Under the influence of its own deformation external force, the seal 43 is tightly attached to the inner and outer walls of the pipeline 1, thereby realizing the rapid switching of a section of the cut of the pipeline 1. The same operation is performed on another pipeline to complete the connection of the pipeline.
[0027] It should be added that the length of the inner support ring 42 is at least twice that of the outer clamping ring 41, which can increase the volume of the seal 43 and improve the sealing effect. Similarly, the lengthened inner support ring 42 can adapt to the irregular incision of the pipeline 1 and ensure the stability of the seal under the premise of uneven incision.
[0028] like Figure 3 As shown, the inner support ring 42 includes a horizontal section and a concave section, and the seal 43 includes a horizontal section and a convex section that cooperate therewith, wherein the convex section of the seal 43 and the concave section of the inner support ring 42 cooperate to form a first sealing structure, and the horizontal sections of the two cooperate to form a second sealing structure, thereby increasing the sealing stability by means of double sealing.
[0029] In order to prevent the inner support ring 42 from being eroded and causing the pipe to fall off during medium transmission, further, the inner support ring 42 and the sealing member 43 are combined as a whole, and a section facing the medium transmission direction of the pipeline 1 is an inclined structure. The combined surface of the inclined structure is subject to reduced impact force from the medium, thereby preventing erosion and pipe falling off.
[0030] In another embodiment, the transfer tube 2 is a "corrugated" structure, and its corrugated section is a deformable part; when adjacent pipes are bent and transferred, the transfer tube 2 with the "corrugated" structure can be bent by the deformation of the corrugated section, and the transfer tube 2 can be used for medium transmission instead of the elbow pipe.
[0031] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the claims attached to the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the attached claims, or the equivalent forms of such scope and boundaries.
