Summary of the invention
The object of this invention is to provide a kind of machinery static sealing integrated sealing lid, its device has that good airproof performance, safe and reliable, system are simple, compact conformation, the easy to maintenance and commutative feature of consumable accessory, the artificial closely unhandy particular surroundings requirement such as to meet under water or radiation dose is larger simultaneously.
The invention provides a kind of integrated sealing lid arrangement, described device comprises: top board, air compression system, gas bag, tracheae, connecting rod, bolt, pad, nut, hook, pull bar, gas cap, bellows, back plate, bellows upper bush, bellows lower sleeve, blind flange, seal ring; Bellows lower end is welded on blind flange, and bellows lower sleeve and bellows upper bush are welded on blind flange and back plate respectively, the upper end of bellows and back plate welding assembly, and the gas cap being assembled with tracheae and gas bag is in advance welded on back plate upper end; Pull bar is through back plate and blind flange thread connection; Top board, connecting rod, hook and back plate are assembled into one by bolt, pad, nut.
Further, described integrated sealing lid arrangement can embrace airtight container corresponding to described device by hook under Gravitative Loads, inflated in gas bag by air compression system, gas enters in the cavity of bellows by tracheae, with the increase of gaseous tension, force bellows expansion, oppositely force is on blind flange, seal ring pressurized on described airtight container, reaches the effect of sealing.
Further, when described integrated sealing lid arrangement needs dismounting, device carries out pressure release, bellows contract, and hoist lifting hook is connected with the suspension ring of top board and upwards promotes, and by connecting rod and pin effect, hook outwards opens, and completes dismounting.
Further, described top board has upper stop block, and described hook has lower stop block; Described upper stop block and lower stop block play position-limiting action, ensure that connecting rod can only be movable within the specific limits, avoid the unrestricted decline of top board.
Further, pull bar is through back plate and blind flange thread connection, during device pressure release dismounting, the welding force started by bellows, bellows lower sleeve and blind flange promotes, when carrying to certain altitude, the threaded function power of pull bar and blind flange starts stressed, and above-mentioned welding force common guarantee promotes intensity.
Integrated sealing lid arrangement of the present invention is from being installed to dismounting, and whole process can realize by remote servicing, and avoid drawback and the trouble of the special manual operation inconvenience brought of environment, compact conformation, system is simple.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
Integrated seal cover assembly structure and sealing principle schematic diagram as Figure 1-4, bellows 14 lower end is welded on blind flange 19, again bellows lower sleeve 18 and bellows upper bush 17 are welded on blind flange 19 and back plate 16 respectively, then by the upper end of bellows 14 and back plate 16 welding assembly, and the gas cap 13 being assembled with tracheae 4 and gas bag 3 is in advance welded on back plate 16 upper end.By pull bar 11 through back plate 16 and blind flange 19 thread connection.Again top board 1, connecting rod 5, hook 9 and back plate 16 are assembled in one by bolt 6, pad 7, nut 8.Finally utilize hoist lifting hook to be vertically put in by whole device to install in advance on the airtight container 21 of seal ring 20.
Airtight container 21 can be embraced by hook 9 under integrated sealing lid Gravitative Loads, inflated in gas bag 3 by air compression system 2, gas enters in bellows 14 cavity by tracheae 4, with the increase of gaseous tension, force bellows expansion, reverse force is on blind flange 19, and seal ring 20 pressurized, reaches the effect of sealing.
When integrated sealing lid needs dismounting, device carries out pressure release, and bellows 14 shrinks, and hoist lifting hook is connected with top board 1 suspension ring and upwards promotes, by connecting rod 5 and pin effect, and structure shown in outside flare up Fig. 5 and Fig. 6 of hook 9.Bellows 14, bellows lower sleeve 18 are welded as a whole with blind flange 19, and pull bar 11, through back plate 16 and blind flange 19 thread connection, when crane upwards promotes, by above-mentioned application force, realizes the integral demounting of seal cover cap.
Upper stop block 10 and lower stop block 15 play position-limiting action, ensure that connecting rod 5 can only be movable within the specific limits, avoid the unrestricted decline of top board 1; Pull bar 11 and the thread connection of blind flange 19, play the application force strengthening back plate 16 and blind flange 19, prevents bellows 14, bellows lower sleeve 18 from welding force strength with blind flange 19 and rupture not.
Obviously, those skilled in the art can carry out various change and modification to the present invention and not depart from the spirit and scope of the present invention.Like this, if belong within the scope of the claims in the present invention and equivalent technology thereof to these amendments of the present invention and modification, then the present invention is also intended to comprise these change and modification.
