Problems solved by technology
[0002] During the storage and transportation of equipment and pipelines in the production plant, the pipelines are often perforated and cracked due to various reasons such as corrosion and freezing, causing the medium in the pipelines to leak. Due to untimely plugging, the leakage directly endangers production safety, damages the surrounding environment, and causes economic losses
[0003]The plugging method of the existing carbon steel pipeline is generally to repair the pipeline with perforation or crack, but due to the existence of the medium in the pipeline, when repairing welding The medium in the pipeline must be stopped, so the method used for repair welding is not ideal

Embodiment Construction
[0016] Such as figure 1 , figure 2 , image 3 As shown, a chain-type pipeline plugging jig includes a locking chain 1, a plugging sheath 2, a sealing gasket 3, and a fastening screw 4. The plugging sheath 2 is bound by the locking chain 1 and can be positioned at On any point of the locking chain 1, the gasket 3 is pasted on the plugging sheath 2, and one end of the locking chain 1 is provided with a chain hook 5, and the chain hook 5 is connected with the locking chain 1 by the fastening screw 4.
[0017] Such as Figure 4 As shown, for pipelines with longer cracks, the leak-stopping sheath 2 can be bound by one or more locking chains 1 .
[0018] The plugging sheath 2 is provided with a sealing body 6 that can pass through the sealing gasket 3 . The sealing body 6 is a cylindrical structure, and a cone with positioning and sealing functions is arranged on the top end thereof.
[0019] When the pipeline leaks, align the plugging sheath 2 with the leakage site, hang the...

The invention discloses a chain type leakage stoppage fixture for a pipe, which comprises a locking chain, a leakage stoppage sheath, a sealing gasket and a fastening screw. The leakage stoppage sheath is bound by and fixed to the locking chain, the sealing gasket is adhered to the leakage stoppage sheath and one end of the locking chain is provided with a chain hook connected with the locking chain through the fastening screw. As the locking chain is arranged, the fixture is not only suitable for pipes with relatively small external diameter but also for pipes with relatively large external diameter as well as for pipe sections with certain taper and irregular pipes or containers; the leakage stoppage sheath is provided with a positioning and sealing cone and has the function of positioning holes, fixing the sealing gasket and assisting in sealing. Compared with the prior art, the leakage stoppage operation is convenient and fast, and the leakage stoppage effect is good.
Description
technical field [0001] The invention relates to a pipeline engineering accessory, in particular to a bundled emergency repair piece for pipeline plugging. Background technique [0002] During the storage and transportation of equipment and pipelines in production facilities, pipeline perforations and cracks are often caused by various reasons such as corrosion and freezing, causing leakage of the medium in the pipeline. Due to untimely plugging, the leakage directly endangers production safety and damages the pipeline. environment and cause economic loss. [0003] The leak plugging method of existing carbon steel pipelines is generally to repair the pipeline with perforation or cracks. However, due to the existence of the medium in the pipeline, the medium in the pipeline must be stopped during repair welding. Therefore, the method used in repair welding is not not ideal. Contents of the invention [0004] The technical problem to be solved by the present invention is...
