AI Technical Summary

Problems solved by technology

Directly adopting the traditional groove clamp connection method cannot prevent its end face from contacting with the conveying medium water. After its end face contacts with the conveying medium water, the end face will cause corrosion and pollute drinking water, resulting in unqualified sanitary conditions for drinking water. At the same time, Corrosion can cause water leakage accidents and greatly shorten the service life of composite pipes

Embodiment 1

[0051] This embodiment is a pipeline butt joint structure, refer to figure 1 and figure 2 , including the clamp 2, the first sealing ring 3, the pipe body 5 of the two butted pipes and the two pipe end sleeves 1. The two pipe end sleeves 1 are respectively sleeved on the ends of the pipe bodies 5 of the two butted pipes to protect the end faces of the pipe bodies 5 .

[0052] refer to image 3 , Figure 4 and Figure 5 , The pipe end sleeve 1 includes an inner support body 11 , an outer body body 12 and an end sealing disc 13 . Both the inner support body 11 and the outer body body 12 are torus. The ends of the inner support body 11 and the outer body 12 are connected through the end sealing plate 13, so that the inner support body 11, the outer body 12 and the end sealing plate 13 are connected into an integrated structure. In the integrated structure, the inner support body 11 , the outer body body 12 and the end sealing plate 13 are coaxial, and the inner support bod...

Embodiment 2

[0066] This embodiment is a pipe butt joint kit, which is used for pipe butt joint. The pipe butt joint kit is composed of the pipe butt joint structure of the first embodiment except the pipe body 5 to be butted. When these components are used to butt the pipe bodies of two butted pipes, they can form the pipe butt joint structure in the first embodiment.

Embodiment 3

[0068] This embodiment is a pipe butt joint method, which is used for the assembly of the pipe butt joint structure in the first embodiment, especially for figure 1 Assembly of the illustrated pipe butt joint structure. The pipeline docking method includes the steps of:

[0069] S1: put the second sealing ring 4 into the sealing groove 111;

[0070] S2: Snap the pipe end sleeve 1 covered with the second sealing ring 4 into the pipe end of the butt pipe body 5, so that the end of the pipe body 5 of the butt pipe is snapped into the pipe groove 14, and the pipe body 5 is The end surface is covered by the pipe end sleeve 1, and the inner support body 11 is attached to the inner surface of the pipe body 5 of the butt pipe, and the outer body 12 is attached to the outer surface of the pipe body 5 of the butt pipe;

[0071] S3: When the end of the pipe body 5 to be butted is rolled through the groove machine to roll the clamping groove 51, when rolling the clamping groove 51, it f...

Abstract

The invention discloses a pipeline butt joint suite, a pipeline butt joint structure and a pipeline butt joint method. The pipeline butt joint suite mainly comprises a pipe end sleeve. The pipe end sleeve comprises an inner supporting body, an outer sleeve body and an end sealing disc. The inner supporting body and the outer sleeve body are both circular ring bodies, and the outer diameter of the inner supporting body is smaller than that of the outer sleeve body. The end of the inner supporting body and the end of the outer sleeve body are connected through the end sealing disc, so that a pipeline groove of a U-shaped structure is formed between the inner supporting body and the outer sleeve body. According to the pipeline butt joint suite, the pipeline butt joint structure and the pipeline butt joint method, when the pipe end sleeve is used for pipeline butt joint, the end portion of a pipe body of a butt joint pipeline is clamped into the pipeline groove, so that the end face of the pipe body is wrapped by the pipe end sleeve, sealing of a sealing ring is matched, the end face notch of the end portion of the pipe body is prevented from making contact with liquid flowing in a pipeline, and therefore the problem that the end face notch of the end portion of the pipeline is corroded is avoided.

Description

technical field [0001] The invention relates to a butt joint structure between pipes. Background technique [0002] In order to improve the quality of drinking water and prevent some elements harmful to human body from entering drinking water due to long-term corrosion of the inner wall of metal pipe fittings by water and endangering human health, metal composite water delivery pipes have been widely used. At present, the connection of reinforced stainless steel pipes (or lined stainless steel composite pipes or steel-plastic composite pipes) whose nominal size is not less than DN50 is generally connected by groove clamps. This connection method is safe and reliable, and the construction is simple and the construction cost is low. However, lined stainless steel composite steel pipe or reinforced stainless steel pipe is a new type of composite steel pipe. Directly adopting the traditional groove clamp connection method cannot prevent its end face from contacting with the co...
