Leakage preventing assembly for pipeline connection

Abstract

The invention provides a leakage preventing assembly for pipeline connection. The leakage preventing assembly for the pipeline connection comprises a connecting block, wherein connecting holes penetrates two sides of the connecting block; inclined threaded pipelines are in thread connection with parts, corresponding to the connecting holes, at two sides of the connecting block; a first magnetic pole is fixedly connected to the inner side of the connecting block; a spring is fixedly connected to one side, close to each connecting hole, of the first magnetic pole; a second magnetic pole is fixedly connected to one side, far away from the first magnetic pole, of the spring; an arc-shaped block is fixedly connected to one side, far away from the spring, of the second magnetic pole; and a connecting seam is embedded into the connecting block and each inclined threaded pipeline. When the leakage preventing assembly is in use, the first magnetic pole and the second magnetic pole are like poles, the first magnetic pole applies repulsive force to the second magnetic pole to enable the second magnetic pole to slide in a chute; and meanwhile, the second magnetic pole drives the arc-shaped block to be in close contact with the corresponding inclined threaded pipeline, thus the inclined threaded pipelines can be prevented from sliding relative to the connecting block, and moreover, the connecting seam between the connecting block and each inclined threaded pipeline can be sealed through the arc-shaped block, and as a result, the leakage preventing effect is good.

Description

technical field [0001] The invention belongs to the technical field of pipelines, and more specifically relates to a pipeline leakage prevention component. Background technique [0002] When the pipeline is connected, in order to improve the tightness between the pipeline and the connecting component, the pipeline and the connecting component are usually connected with oblique threads, and when the pipeline is subjected to external vibrations, the straight thread pipeline will be separated from the connecting component due to forces in different directions , so it is necessary to connect the oblique thread pipe with the connecting component, but there is a gap between the oblique thread pipe and the connecting component (there is a gap thread fit between the oblique thread pipe and the connecting component). Relative movement is easy to occur in the gap between components, resulting in gas or liquid leakage in the gap between the pipe and the connecting component, and when t...

Problems solved by technology

[0004] In order to solve the above technical problems, the present invention provides an anti-leakage component for pipeline connection to solve the problem that the gap between the oblique thread pipeline and the connection component tends to move relatively when the existing vibrations occur in the outside world, causing the pipeline to When gas or liquid leakage occurs in the gap between the oblique thread pipe and the connection component, and the relative movement occurs in the gap between the oblique thread pipe and the connection assembly, it will lead to poor connection effect between the oblique thread pipe and the connection assembly, and poor practicability
