A kind of pipeline and pipeline connection structure

Abstract

The invention discloses a pipeline and a pipeline connecting structure, wherein the pipeline connecting structure at least comprises a first pipeline (1) with a horn-mouth-shaped inserting opening end (10) and a second pipeline (2) with a horn-mouth-shaped bearing and connecting end (20), the inner side of the inserting opening end (10) is provided with a son metal ring (3), the inner side of the bearing and connecting end (20) is provided with a mother metal ring (4) matched with the son metal ring (3), the outer side of the inserting opening end (10) is sheathed with a first metal flange (7) with the inner diameter smaller than the maximum diameter of the horn-mouth-shaped inserting opening end (10), the outer side of the bearing and connecting end (20) is sheathed with a second metal flange (8) with the inner diameter smaller than the maximum diameter of the horn-mouth-shaped bearing and connecting end (20), and the first metal flange (7) is connected with the second metal flange (8) through a fixing element (9). Through the adoption of the technical scheme, the solderless connection is realized among pipelines of various pipelines such as metal pipelines, plastic pipelines or plastic composite pipes, and the pipeline and the pipeline connecting structure have the characteristics that the connection is convenient, and is not limited by the use environment, and the wear resistance is realized.

Description

technical field [0001] The invention relates to the technical field of pipeline connection, in particular to a pipeline and a pipeline connection structure Background technique [0002] For various pipelines such as existing metal pipelines, plastic pipelines or plastic composite pipes, the connecting structure between the pipelines is mostly directly welded, or connected by movable metal flanges after welding metal flanges. Such a connection structure has some defects to varying degrees: the use of a direct welded joint structure makes it difficult to maintain and replace the pipeline; the use of a metal flange welded connection structure restricts the use environment of the connected pipelines and can be used floating on the water surface When it is easy to break, the cost is high, and the welded metal flange is produced by injection molding, which is not easy to wear and tear. Contents of the invention [0003] The purpose of the present invention is to provide a pipe ...
