Description
Technical field
The utility model relates to a kind of device that leaks hole for stopping up commercial unit, while relating in particular to one for commercial production, transport, storage accident, or naval vessel occur irregular large small holes time, can urgent, fast, effectively directly prevent the one of leaking manually, device for plugging easily.
Background technology
Often there is leakage accident in commercial production, transport, storage.These leakage accidents, particularly chemical frbre industry leakage accident, must quick, safe, prevention effectively.Otherwise very fast significant explosion, the accident such as poisoning of leading to out of control, causes the massive loss of life and property massive losses.This type of leakage accident often occurs.
In the time that the ships water surface below leak occurs, a large amount of penstocks pour in, and carry out not in time urgent leak stopping, may cause ships sinking.
Present disclosed blocking method has more than hundreds of kind.But still lack a kind of better simply, fast speed, directly, safety again can be synthetically, tackle irregular, large pressure, the size of wide range of forms is leaked hole.
In emergency repair leak stopping work, often occur that the most thorny situation is as follows:
1. there are the irregular holes such as concavo-convex or blast shape to leak.With common repair outfit, as timber wedge, Small-pore Leak Stoppage Rifle etc. go to block up, cannot successfully prevent leakage.Because, although large hole block, periphery finedraw also stifled less than, leaking medium gushes from finedraw.
2. when leaking medium injection pressure is large, leak stopping apparatus is difficult to fill in by force leakage hole.If with obstructions such as interior envelope, timber wedge repair outfits, even if sometimes fill in and can be regurgitated out.
3. leakage accident is often unpredictable.Sometimes leak that hole is little, sometimes to leak hole large.Common repair outfit, size standard is unified.A set of repair outfit cannot meet too many size hole.
4. in the time that macroscopic void leaks, most repair outfits are not to go direct obstruction for hole size.But no matter hole size all adopts similar outsourcing mulching method, large area is coated goes to block up.This not only method heaviness, plugging effect is poor, bears pressure also limited.If external sealing type leak stoppage bag, bundling type etc. are exactly this mode.
5. often thousand kind of hundred sample of leakage accident equipment and leak position.Sometimes leak hole location special, as in equipment edge, bottom etc.This form is leaked, and for emergency leakage blocking, specially refers to inflammable and explosive gas-liquid and leaks, and does not still have a kind of good, actv. blocking method to solve.
6. existing most of repair outfit is all with carbon steel ferrous metal or stainless steel material manufacture.While running into inflammable and explosive gas-liquid leakage, can not easily produce pyrophoric repair outfit with these, collision may be blasted.
7. when leakage accident, the inflammable and explosive gas-liquid that runs into large pressure leaks, and produces high-pressure injection.Long-time injection easily produces static cloud.Leak stopping by force on one side, allows it spray probably because electrostatic accumulation sets off an explosion on one side.
Existing to leak hole stop up band see there is following several method:
The one, emergency wooden wedge, makes circular cone or tilted conical by wood, and the most advanced and sophisticated hole leaking of aiming at, beats and fill in.Its maximum shortcoming is that, when hole is slightly irregular, timber wedge is just difficult to be completely closed.Simultaneously also can because of interior pressure, too senior general's timber wedge be counter releases, cause leak stopping failure.When leaking the wall of hole when thinner or cellular leakage, forbid adopting leak stopping in this way.Adopt in this way by mistake, may lead to larger disaster.Timber wedge leak stopping the most ancient this leak stopping mode, has lagged far behind modern industry.But still having people to use, is because there is no better substitute.
The 2nd, be called the repair outfit of Small-pore Leak Stoppage Rifle, with rubber make hollow as timber wedge the sack of all size.When leak stopping, the most advanced and sophisticated circular cone bag hole of aiming at leakage is filled in to air pressure inflation circular cone airbag.Its mode is more progressive to some extent than timber wedge, and plugging effect is slightly better than timber wedge.But accessory is more, operation is trouble also, can do with pressure very low.And the anxiety that is likely punctured of airbag.When hole is less, airbag can not insert in stage casing while use, poor by sharply filling in one little section of effect.Insert when too shallow, also can because of interior pressure, too senior general's circular cone bag be counter releases, cause leak stopping failure.But maximum shortcoming remains, when hole is not that rule is circular or square, slightly irregular, edge is burr slightly, is just difficult to leak hole and seals completely.
The 3rd, with the leak stopping of T font screw, a T font is stretched in hole, cross bar is stuck in hole, at the montant bolt upper flat plate pad of locking, stops gas-liquid in hole to release.But in the time that leak outside face is uneven, hole cannot be blocked completely in T font, and leak is sealed.In the time that leak has very large pressure to leak, cannot fill in hole, operation easier is larger simultaneously.In T font, press inequality, may cause leak stopping not tight.
Certainly also have and directly use self-tapping screw, directly screw in small holes with compressing tablet and stop up.Also usefully tie up, the various blocking methods such as welding, injecting glue.
The technology being close with the utility model has the patents such as CN2043217U, CN2108055U, CN102278471A, CN101670879A.
There is leakage accident in commercial production, transport, storage, often ferments the part of accomplishing anything.Particularly inflammable and explosive generation is leaked and is caused that huge explosion event happens occasionally.How to design one and be simple and easy to use, aim at leak target, directly stop up.Safe and reliable again, simple and quick method is for having pressure, irregular hole target to carry out fast blocking again.This is the urgent method and apparatus of being badly in need of of Safety Technology for Industry personnel.
When ships is leaky, carry out urgent fast by irregular, have pressure, indent, jagged hole to stop up.Conventional have the several different methods leak stopping such as interior top formula, external-compression type, umbrella formula, inflatable, and its obstruction method mode comparatively bothers, complex structure, and operation is difficult, and efficiency is low, weak effect.Ships still need a kind of can be simple, fast, effectively, stop up irregular, have pressure, indent, a jagged hole method.
