Envelope can not meet functional requirement.
The content of the invention
It is an object of the invention to provide a kind of mechanical static seal integrated sealing lid, its device has good airproof performance, peace
Complete reliability, simple system, compact conformation, the commutative feature of easy to maintenance and consumable accessory, while satisfaction is under water or radiation agent
Measure the artificial closely unhandy particular surroundings of larger grade to require.
The present invention provides a kind of integrated sealing lid arrangement, and described device includes：Top board, air compression system, gas bag, gas
Pipe, connecting rod, bolt, pad, nut, hook, pull bar, gas cap, bellows, support plate, bellows upper bush, bellows are trapped
Cylinder, blind flange, sealing ring；Bellows lower end is welded on blind flange, and bellows lower sleeve and bellows upper bush are respectively welded
On blind flange and support plate, upper end and the support plate welding assembly of bellows, pre-assembly have the gas cap weldering of tracheae and gas bag
It is connected on support plate upper end；Pull bar is through support plate and blind flange thread connection；Top board, connecting rod, hook and support plate by bolt,
Pad, nut are assembled integrally.
Further, under Gravitative Loads can to embrace described device by hook corresponding for the integrated sealing lid arrangement
Sealing container, is inflated into gas bag by air compression system, and gas is entered by tracheae in the cavity of bellows, with gas pressure
The increase of power, forces bellows expansion, and reversely, on blind flange, the sealing ring in the sealing container is pressurized, reaches close for force
The effect of envelope.
Further, when the integrated sealing lid arrangement needs dismounting, device carries out pressure release, and bellows shrinks, crane
Suspension hook is connected with the suspension ring of top board and is lifted up, and is acted on by connecting rod and pin, and hook is flared out, and completes dismounting.
Further, the top board has upper stop block, and the hook has lower stop block；The upper stop block and it is lower only
Block plays position-limiting action, it is ensured that connecting rod can only be movable within the specific limits, it is to avoid the unrestricted decline of top board.
Further, pull bar is through support plate and blind flange thread connection, when device pressure release is dismantled, start by bellows,
Bellows lower sleeve is lifted with the weld force of blind flange, and when carrying to certain altitude, pull bar is started with the threaded function power of blind flange
Stress, and above-mentioned weld force common guarantee lifting intensity.
From being installed to dismounting, whole process can remote-controlled operation realization, it is to avoid ring for the integrated sealing lid arrangement of the present invention
The special artificial unhandy drawback brought in border and trouble, compact conformation, simple system.

Specific embodiment
With reference to the accompanying drawings and examples the present invention is described in detail.
Integrated seal cover assembly structure and sealing principle schematic diagram, 14 lower end of bellows is welded as Figure 1-4
In blind flange 19, then bellows lower sleeve 18 and bellows upper bush 17 are respectively welded on blind flange 19 and support plate 16,
Then by the upper end of bellows 14 and 16 welding assembly of support plate, and tracheae 4 and the gas cap 13 of gas bag 3 weld pre-assembly
In 16 upper end of support plate.By pull bar 11 through support plate 16 and 19 thread connection of blind flange.Again by top board 1, connecting rod 5,9 and of hook
Support plate 16 is assembled in one by bolt 6, pad 7, nut 8.Finally whole device is vertically put in using hoist lifting hook and is carried
Before install in the sealing container 21 of sealing ring 20.
Sealing container 21 can be embraced by hook 9 under integrated sealing lid Gravitative Loads, by air compression system 2 to gas
Inflation in bag 3, gas are entered in 14 cavity of bellows by tracheae 4, with the increase of gas pressure, force bellows expansion, instead
To force on blind flange 19, sealing ring 20 is pressurized, reaches the effect of sealing.
When integrated sealing lid needs dismounting, device carries out pressure release, and bellows 14 shrinks, hoist lifting hook and 1 suspension ring of top board
Connection is lifted up, and is acted on by connecting rod 5 and pin, and hook 9 is flared out into structure shown in Fig. 5 and Fig. 6.Bellows 14, ripple
Line pipe lower sleeve 18 is welded as a whole with blind flange 19, pull bar 11 through support plate 16 and 19 thread connection of blind flange, crane to
During upper lifting, by above-mentioned active force, the integral demounting of closure is realized.
Upper stop block 10 and lower stop block 15 play position-limiting action, it is ensured that connecting rod 5 can only be movable within the specific limits, it is to avoid
The unrestricted decline of top board 1；Pull bar 11 and the thread connection of blind flange 19, play a part of to strengthen support plate 16 and blind flange 19
Power, prevents bellows 14, bellows lower sleeve 18 from not enough rupturing with the welding force strength of blind flange 19.
Obviously, those skilled in the art can carry out the essence of various changes and modification without deviating from the present invention to the present invention
God and scope.So, if these modifications and modification to the present invention belong to the model of the claims in the present invention and its equivalent technology
Within enclosing, then the present invention is also intended to comprising these changes and modification.
