Abstract
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
The present invention relates to a kind of pipework accessory, especially a kind of strap-on pipe plugging is with rushing to repair part.
Background technique
When the equipment in process units, oil pipeline and storage, often a variety of causes such as congeal because of burn into and cause pipe perforation, crackle, pipeline internal medium is revealed, untimely because of leak stopping, the thing that leaks directly jeopardizes production safety, destroys surrounding environment, causes economic loss.
The leak stopping mode of existing carbon steel piping is that the pipeline that perforation or crackle will occur carries out repair welding generally speaking, but because the existence of pipeline internal medium must stop medium in the conveyance conduit during repair welding, so the method that adopts during repair welding is unsatisfactory.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned deficiency and a kind of simple and practical, easy to operate chain pipe plugging chucking tools is provided.
The present invention is for solving the problems of the technologies described above the following measure of taking: a kind of chain pipe plugging chucking tools, comprise locking chain, leak stopping sheath, sealing gasket, fastening screw, described leak stopping sheath is locked the chain constraint and is positioned on the locking chain, sealing gasket sticks on the leak stopping sheath, locking chain one end is provided with the chain hook, and the chain hook is connected by fastening screw with the locking chain.
For the pipeline that has than the long crack class, the leak stopping sheath be subjected to 1 or more than many locking chain fetter.
The leak stopping sheath is provided with the seal that passes sealing gasket.Seal is the round column structure body, and its top is provided with the cone with location, seal action.
The present invention so not only be fit to the less pipeline of outside dimension, also is fit to the bigger pipeline of outside dimension owing to be provided with the locking chain, also is applicable to the pipeline section that has certain taper and the leak stopping of irregular pipeline or container simultaneously; The leak stopping sheath is provided with location, seal cones, the effect that can play location, hole, fixing seal pad and assist to seal.Compared with prior art, leak stopping is convenient to operation, and plugging effect is good.

Fig. 2 is leak stopping sheath of the present invention and gasket structure schematic representation
Fig. 3 is for chain of the present invention is linked up with, fastening screw side structure schematic representation

Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, a kind of chain pipe plugging chucking tools, comprise locking chain 1, leak stopping sheath 2, sealing gasket 3, fastening screw 4, described leak stopping sheath 2 is locked chain 1 constraint and can be positioned on the arbitrfary point of locking chain 1, sealing gasket 3 sticks on the leak stopping sheath 2, locking chain 1 one ends are provided with chain hook 5, and chain hook 5 is connected by fastening screw 4 with locking chain 1.
As shown in Figure 4, for the pipeline that has than the long crack class, leak stopping sheath 2 can be subjected to the constraint of 1 or many locking chain 1.
Leak stopping sheath 2 is provided with the seal 6 that can pass sealing gasket 3.Seal 6 is the round column structure body, and its top is provided with the cone with location, seal action.
When pipeline takes place to leak, leak stopping sheath 2 is aimed at leakage position, chain hook 5 hangs up properly locking chain 1, then, tightens the fastening screw 4 on the chain, makes leak stopping sheath 2 progressively compress sealing gasket 3, seals fully to cause itself and pipeline, no longer leaks.Pipe plugging sheath 2 and sealing gasket 3 can be according to the different different shapes that are designed to of pipe leakage point.When the perforation of shutoff point is leaked, can use monolithic leak stopping sheath, sealing gasket and single locking chain can realize the shutoff purpose, after seal passes sealing gasket above the leak stopping sheath, cone tip portion is exposed 1/2 length of sealing gasket thickness, the effect that makes seal can play location, hole, fixing seal pad and assist to seal.When running into Crack Leakage, when just leakage position is wire, just can adopt monolithic leak stopping sheath, sealing gasket and the tight chain of twin-lock even many locking chains to carry out shutoff.When pipeline need weld, can around the leak stopping sheath of good seal, directly carry out weld job.
The present invention is not limited to above embodiment, and every other mode of executions that drawn by those skilled in the art's technological scheme according to the present invention belong to the scope of protection of the invention equally.
