Embodiment Construction
[0015] see Figure 1-Figure 2 As shown, the technical solution adopted in this specific embodiment is: it is composed of the first fixture 1, the second fixture 2, the plugging sealing chamber 21, the glue injection nozzle 22, the pipeline 3, and the leakage point 4. The first fixture 1 is installed on one side of the second fixture 2, the first fixture 1 is a rotating end cover, and the eccentric point is adjusted by rotating the end cover to solve the original problem. The inside of the second fixture 2 is a plugging sealing chamber 21, A glue injection nozzle 22 is installed above the second jig 2 , the pipeline 3 is arranged inside the first jig 1 and the second jig 2 , and there is a leakage point 4 on the pipeline 3 . The eccentric point of the non-concentric fixture can be accurately guaranteed during the installation process, which will not lead to the phenomenon that the fixture installation forcibly corrects the concentricity of the pipeline, resulting in enlarged pi...

The invention discloses a small-diameter non-concentric pipeline leaking stoppage fixture, and relates to the technical field of pipeline leaking prevention fixtures. The small-diameter non-concentricpipeline leaking stoppage fixture comprises a first fixture, a second fixture, a leaking stoppage sealing cavity, a glue injection nozzle, a pipeline and a leaking point, wherein the first fixture isfixedly connected to one side of the second fixture, the first fixture is a rotary end cover, the leaking stoppage sealing cavity is formed in the second fixture, the glue injection nozzle is arranged on the second fixture, the pipeline is arranged in the first fixture and the second fixture in a penetrating mode, and the leaking point is arranged on the pipeline. By adopting the technical scheme, the pipeline leaking stoppage fixture has the beneficial effects that the structural design is reasonable, the eccentric point can be accurately guaranteed, the situation that the installation of the fixture forcibly corrects the concentricity of the pipeline does not occur, the phenomena that pipe cracks are enlarged and even the pipe is broken are avoided, the original problems are solved, andthe application and popularization are facilitated.
Description
technical field [0001] The invention relates to the technical field of leak-proof fixtures for pipelines, in particular to a leak-stopping fixture for small-diameter non-concentric pipelines. Background technique [0002] In industrial and agricultural production and people's daily life, oil, gas, and water pipelines often occur due to aging and perforation, which not only causes oil, gas, and water losses, but also pollutes the environment. Small-diameter pipes have non-concentric butt welding joints, and it is difficult to make fixtures after welding joints leak. However, the eccentric point of non-concentric fixtures made according to measurement cannot be accurately guaranteed during installation, which will cause the fixture installation to forcibly correct the pipe concentricity. Cause pipeline crack to increase, even pipeline breaks, is unfavorable for popularizing and using. Contents of the invention [0003] The object of the present invention is to aim at the de...
