Description
Technical field
The utility model belongs to sealing assembly or service technique field, and in particular to a kind of pressure rubber-injection sealing device.
Background technique
As the requirement to aircraft is higher and higher, use environment is more and more harsher, and designer is to aircraft sky
Between design it is more and more compacter, if so leakage occur at the position adjacent with integral tank, then will appear the construction of type chamber
Space is smaller, the more difficult problem of operation.Wherein carrying out part or a wide range of disassembly to seepage place becomes leakaging repairment
One method, if but sealing structure is dismantled, it is possible to the leakage at other positions can be caused, this measure will be obtained and not repaid
It loses.If in addition, carry out injecting glue sealing to type chamber, for the open upward method that can use vertical injecting glue, but for
Opening is horizontal or downward type chamber, using the injecting glue of no pressure, it will cause sealant arbitrarily to trickle, the sealant after vulcanization
Uncompacted situation is unreliable so as to cause sealing performance.Therefore, for such situation, best mode be exactly to type chamber into
Row pressure injecting glue.
Utility model content
To solve the above problems, the utility model provides, a kind of auxiliary solves injecting glue process and sulfidation is difficult to pressure maintaining
Technical problem, thus the sealing assembled technological device that the intracavitary sealant of guarantee type is closely knit.
A kind of pressure rubber-injection sealing device, including internal stop, outer baffle block, rubber seal, screw, sealant cloth, note
Sebific duct, exhaust pipe, internal stop are provided with positioning pin, the location hole matched with the positioning pin of internal stop are provided on outer baffle block,
Internal stop top is provided with gas vent, and internal stop lower part is provided with hole for injecting glue, is provided with connection through-hole, exhaust pipe in the middle part of internal stop
It is connect with the vent hole seal of internal stop, the hole for injecting glue of injected rubber hose and internal stop is tightly connected, and the connection of screw and internal stop is logical
Hole connects, and is provided with sealed groove corresponding with rubber seal outside outer baffle block, the close of outer baffle block is arranged in rubber seal
It seals in groove.
Further, the positioning pin number of the internal stop of the pressure rubber-injection sealing device and the positioning hole number of outer baffle block are 2
~4.
Further, the positioning pin of the internal stop of the pressure rubber-injection sealing device is trapezoidal, and bevel edge angle is 145~155 °.
It is had the beneficial effect that by what the technological means the utility model obtained, which can not only be
The intracavitary gas of type is discharged during injecting glue, while keeping the state of high pressure in sulfidation, thus after guaranteeing vulcanization
Sealant is closely knit, compact, is effectively guaranteed sealing performance.
Detailed description of the invention
Fig. 1: for the structural schematic diagram of the utility model.
1, internal stop；2, outer baffle block；3, rubber seal；4, screw；5, sealant cloth；6, injected rubber hose；7, exhaust pipe.
Specific embodiment
More detailed description is done to the embodiments of the present invention below in conjunction with attached drawing.
A kind of pressure rubber-injection sealing device, including internal stop 1, outer baffle block 2, rubber seal 3, screw 4, sealant cloth
5, injected rubber hose 6, exhaust pipe 7, internal stop 1 are provided with positioning pin, are provided on outer baffle block 2 and match with the positioning pin of internal stop 1
Location hole, 1 top of internal stop is provided with gas vent, and 1 lower part of internal stop is provided with hole for injecting glue, the company of being provided in the middle part of internal stop 1
Hole is connected, exhaust pipe 7 is connect with the vent hole seal of internal stop 1, and the hole for injecting glue of injected rubber hose 6 and internal stop 1 is tightly connected, screw
4 connect with the connection through-hole of internal stop 1, and sealed groove corresponding with rubber seal 3 is provided with outside outer baffle block 2, and rubber is close
Seal 3 is arranged in the sealed groove of outer baffle block 2.
In order to play the role of positioning, and block 2 is facilitated to take out from internal stop 1,1 positioning pin of internal stop be it is trapezoidal, tiltedly
Corner degree is 150 ° ± 5 °.
In order to make the rubber seal 3 in 2 outer fringe seal groove of outer baffle block play good sealing function, outer baffle block 2 with
Maximum gap is 0.5mm between type inner cavity surface.
It is accurate in order to make to cooperate between internal stop 1 and outer baffle block 2, in the device of pressure injecting glue sealing on internal stop 1
The number of positioning pin is 2 to 4.
In use, the positioning pin on internal stop 1 is inserted into the positioning hole on outer baffle block 2, and use quick adhesive
It is fixed, while in the gas vent and hole for injecting glue for using putty cloth 5 that injected rubber hose 6 and exhaust pipe 7 are sealably coupled on outer baffle block 2,
Then connection is finished and outer edge is pushed into type chamber equipped with the assembled technological device of rubber seal 3, then starts to lead to
The injected rubber hose 6 for crossing connection air compressor injects glue of the viscosity within the scope of 300mps~800mps, to occur in exhaust pipe
After glue, injecting glue and exhaust bubble are carried out by the way of slow, multiple injecting glue, is the intracavitary sealant of guarantee type in hyperbaric environment
Under vulcanized, after continuous glue occurs in exhaust pipe, successively exhaust pipe 7 and injected rubber hose 6 are blocked, finally in sealant
After vulcanization, outer baffle block 2 is released by screwing in screw 4, and internal stop 1 is taken out.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solutions of the utility model, the technology of the art
Personnel embody the principles of the present invention to some variations that some of them part may be made, and belong to the utility model
Protection scope within.
