Capsule ontology fills in its internal groove along internal whorl bar, finally fixes airbag body and annular air-pocket；
Again by rubber O-ring seal be mounted on block bolt internal whorl bar bottom, then make pipeline pass through block bolt,
Rubber O-ring seal, then the internal whorl bar of bolt alignment rigid waterproof sleeve will be blocked, rotation blocks bolt to tightening completely；
3. starting to inflate to annular air-pocket after the completion of pipelining, when pressure reaches authorized pressure value, stop filling
Gas completes the installment work of bolt inflatable seal device.
The external nut for blocking bolt is hexagonal layout.
The groove of the internal whorl bar is annular.
Cyclic annular water-proof strip is also attached with inside the airbag body,
1. middle rigid waterproof sleeve both ends carry out internal mantle fiber to the step, it is desirable that 8~10mm of port reserves a Duan Bujin
Row mantle fiber, both ends 50~80mm of mantle fiber depth.
The beneficial effects of the present invention are: 1) of the invention by using built-in annular air-pocket plugging device realization pipeline and outer
The closure of part device is handled, and simple and reasonable, waterproof effect is good；2) present invention realizes external by using ring-shaped rubber pad
Closure between device and preserved pipeline inner wall, construction is simple, waterproof effect are good, conducive to the maintenance and replacement in later period；3) originally
Invention can form standardization pipe plugging component, be conducive to batch production and process, improve quality standard；4) present invention uses steel material
In conjunction with rubber material, the characteristic expanded with heat and contract with cold can be resisted for a long time compared with traditional fire-proof mud blocks, reduces later period maintenance
Frequency；5) the external bolt shape for using standard of the present invention, after pipeline blocks, surface impression quality is good；6) present invention uses
Screw thread is threadedly coupled, and is improved and is blocked installation quality and fastening effect, accurate to control pipeline hole location.
