Detailed description of the invention
With detailed description of the invention the present invention done the most concrete detailed description below in conjunction with the accompanying drawings.
As it can be seen, a kind of air sac sealing sleeve expansion joint, including sealed letter, inner sleeve 1 and gland 3, described sealed letter
The sealed letter body 5 including one end with the tubular of outward flange 501 and the support ring 6 being located on sealed letter body 5 inwall, inner sleeve 1
Being set in sealed letter body 5, gland 3 is located between inner sleeve 1 and sealed letter body 5 and passes through bolt with the outward flange of sealed letter body
2 are connected, and specifically, the compressed part of gland 3 are inserted in the space between inner sleeve 1 and sealed letter body 5, by the lid of gland 3
Body is connected with the outward flange of sealed letter body 5.
Being filled with multiple air bag in the space formed between inner sleeve 1, sealed letter and gland 3, multiple air bags are sequentially
An interrupted annular is formed, at adjacent two in being arranged between inner sleeve 1, sealed letter and gland 3 space formed
It is provided with the baffle plate for separating two air bags between air bag, can connect fixing with the inwall of sealed letter body 5 for baffle plate side
Connecing, the bit shift compensation effect of the present invention can be slided to realize relative to inner sleeve 1 in the another side relative with this side.
Each air bag is equipped with the suction nozzle 9 for being filled with gas-pressurized in air bag, sealed letter body 5 is provided with
Coordinate the pressurization mouth installed with suction nozzle 9, the quantity of pressurization mouth is consistent with the quantity of suction nozzle 9；Suction nozzle 9 reaches pressurization
The outside of mouth, is additionally provided with the coil pipe 13 being connected with each suction nozzle, is provided with and always adds on coil pipe 13 in the periphery of sealed letter body 5
Pressure mouth, for being connected with source of the gas.
It is connected, at air bag 4 by inner pressure ring 10, outer press ring 11 and a nut 12 between described suction nozzle 9 and air bag 4
Being provided with an installing hole, suction nozzle 9 is located in installing hole, and one end that suction nozzle 9 extend within air bag 4 is threaded connection
Inner pressure ring 10, suction nozzle 9 reaches the part outside air bag 4 and has been threaded connection outer press ring 11, and outer press ring 11 is arranged on close
In the groove offered on packing body 5 inwall, the degree of depth of groove and the consistency of thickness of outer press ring.
Described inner pressure ring 10 and suction nozzle 9 all vulcanize together with air bag 4 to be made, and i.e. carries out sulfuration when making air bag 4, will enter
Valve 9 loads in inner pressure ring 10, puts corresponding position in a mold, and air bag is connected as with inner pressure ring 10 and suction nozzle 9 when being formed
One entirety.
Such structure can ensure that the sealing between suction nozzle 9 and air bag 4.
Inner pressure ring 10 and outer press ring 11 all use metal material to make, the phase of its one side contacted with air bag 4 and air bag 4
Answering face shape consistent, the bottom shape of the groove that the another side of outer press ring 11 and sealed letter body 5 inwall are offered matches.
The one side contacted with air bag 4 at outer press ring 11 is provided with annular seal groove 11a, thus can further enhance air bag
Sealing effectiveness between 4 and suction nozzle 9.
Suction nozzle 9 reaches the part outside sealed letter body 5 and is threaded connection nut 12, thus by suction nozzle 9 with close
Fixing connection between packing body 5.
Described sealed bladder 4 uses mild steel to make, it is also possible to, described sealed bladder 4 uses polyurethane material to make.
According to actual applicable cases, one end of outward flange can not set at sealed letter body 5 and be welded with the adapter 7 of taper.
When the present invention makes, first baffle plate 8 can be welded on the inwall of sealed letter body 5, then inner sleeve 1 is sleeved on close
In packing body 5, then arranging an air bag between every two pieces of baffle plates 8, before inflation, suction nozzle 9 top is to air bag for air bag 4
The distance of inner peripheral surface is not more than inner sleeve 1 outer wall to the distance between sealed letter body 5 inwall, thus suction nozzle 9 can be made from sealing
On letter body 5, corresponding pressurization mouth stretches out.Then coil pipe 13 is connected in the end of suction nozzle.
Finally adjust the gap between gland 3 and sealed letter, connect gland 3 and sealed letter body 5.
In the present embodiment, the number of air bag 4 is four, can select as required in actual application, and described coil pipe 13 sets
Being set to annular, (actual can also be other shape, and the coil arrangement of annular is more compact) is connected, then with each suction nozzle 9
It is filled with gas-pressurized to four air bags by the total pressurization mouth (not shown) on coil pipe 13 simultaneously.To always add after having inflated
Pressure mouth uses capping to seal, and described gas-pressurized can be compressed air, it is also possible to be that nitrogen etc. is lower-cost lazy
Property gas.
It is filled with bulging after gas-pressurized in air bag 4, extrudes the outer wall of the inner sleeve 1 being in contact with it and the interior of sealed letter body 5
Wall thus realize the sealing between inner sleeve 1 and sealed letter body 5, use baffle plate to separate, so that adjacent two between multiple air bags 4
Individual air bag 4 extrudes two plate faces of baffle plate 8 respectively, it is ensured that being effectively tightly connected between adjacent cells.
