Abstract
A kind of rubber gasket with metallic framework, including metallic framework and sealing joint strip, are provided with four link bolt hole outside the metallic framework, skeleton upper and lower surface is respectively provided with one is used to accommodate the groove of sealing joint strip, has some through holes in bottom portion of groove.The beneficial effects of the utility model are：Rubber can bear bigger intensity with metalwork as carrier, expand the range of application and service life of sealing gasket；T font supports are provided with groove, can preferably be combined with adhesive tape, be improve adhesive strength, while support also acts as fixed effect, in hypertonia, there is a power for auxiliary to adhesive tape to improve the ability to bear to pressure, and because rubber and metal adhesive turn into an entirety, so the sealing gasket is convenient installing, it is easy to disassemble, it is easy to storage, while simple structure, scientific and reasonable.
Description
Technical field
The utility model belongs to sealing device technical field, and in particular to a kind of rubber gasket with metal as carrier.
Background technology
Sealing gasket is a kind of in machinery, equipment, pipeline, there is the local sealing spare part of flow of fluid.Existing market
Mainly there are sealing gasket and sealing ring with the seal being commonly used in production, it is asbestos pad, chassis less construction that sealing gasket is most
Rubber blanket, polytetrafluoroethylene (PTFE) cylinder-packing rubber blanket etc..The sealing gasket sealing effectiveness of asbestos pad and other materials is poor, and service life is short,
High cost, and the low intensity that the rubber blanket of bone free frame material and polytetrafluoroethylene (PTFE) cylinder-packing rubber blanket can bear, are used primarily in and ward off
In the preserving and sealing of the low pressure chemical industry equipment such as porcelain, glass pipe, it is impossible to adapt to the sealing needs of elevated pressures pipeline.
Such as in oil way system is gone straight up to, there is high pressure in pipeline, can reach 1-16Mpa, and profit is typically at pipe joint
Sealed with rubber gasket, place it in joint, be connected with connecting bolt corresponding on two pipelines and fasten,
The area that this kind of method rubber gasket bears pressure is larger, is susceptible to seepage and causes potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of rubber gasket with metallic framework, is particularly suitable for pressure duct connection
The sealing at place.
The technical solution of the utility model is：A kind of rubber gasket with metallic framework, including metallic framework and sealing
Adhesive tape, is provided with four link bolt hole outside the metallic framework, skeleton upper and lower surface is respectively provided with one for accommodating sealing joint strip
Groove, have some through holes in bottom portion of groove.
Further：The channel section is rectangle.
Further：Some T-shaped fixed mounts are provided with groove, circular groove is pointed in the upper part of the fixed mount
The center of circle.
Further：Described metal is aircraft aluminum.
Further：The a diameter of 5-200mm of described metallic framework, thickness is 1-35mm.
The beneficial effects of the utility model are：Rubber can bear bigger intensity with metalwork as carrier, expand close
The range of application and service life of packing；T font supports are provided with groove, can preferably be combined with adhesive tape, improve viscous
Intensity is connect, while support also acts as fixed effect, in hypertonia, has a power for auxiliary to adhesive tape to improve to pressure
Ability to bear, it is easy to disassemble so the sealing gasket is convenient install and because rubber and metal adhesive turn into an entirety,
It is easy to storage, while simple structure, scientific and reasonable.
Brief description of the drawings
Fig. 1 is the utility model structural profile schematic diagram；
Fig. 2 is the structural representation of metallic framework in the utility model structure；
Fig. 3 is the utility model structure use state figure；
Fig. 4 is pipeline connection figure.
Number explanation in figure：1 is metallic framework, 2 is sealing joint strip, 3 is link bolt hole, 4 is groove, 5 is through hole, 6
For fixed mount, 7 are pipeline.
Specific embodiment
Below by accompanying drawing, the utility model will be further described.
As Figure 1-4, it is a kind of sealing gasket with metal as carrier of the utility model structure, for the junction of pipeline 7
Sealing, usual pipeline is provided with flange in junction, and flange is provided with four bolts for being connected, and this programme includes metal
Skeleton 1 and sealing joint strip 2, the metallic framework are formed around four link bolt hole 3 for being connected with former pipeline, on skeleton
Lower surface is respectively provided with one is used to accommodate the groove 4 of sealing joint strip, has some through holes 5, the sealing joint strip vulcanization in bottom portion of groove
Or be bonded in groove by adhesive, rubber sticks to inside grooves, slightly protrudes from metal surface 1-3mm, or according to need
Want setting height；Rubber and metalwork are by adhesive bonding by Vulcanization or cold bonding is Nian Jie is integrally formed.
In this structure, sealing joint strip is higher than the height very little of metal surface, under the same conditions, the total pressure for being born
It is relative just small, meanwhile, sealing joint strip is arranged in groove, and side is also subject to recess sidewall to its inside supporting force, makes it
Bear the ability enhancing of pressure.
The through hole can be such that sealing joint strip is smoothly vented in sulfidation, increased vulcanization effect, and then enhance
Airtight quality；Meanwhile, can be connected as one for the sealing joint strip in upper and lower two grooves by the rubber in through hole, enhance glue
The intensity of bar, resistance to exfoliation ability and service life.
Preferably：The channel section is rectangle, can preferably for sealing joint strip provides supporting force.
Preferably：It is provided with some T-shaped fixed mounts 6 in groove, the crossbeam direction of the upper part of the fixed mount can be with
With the diameter of circular groove（By the diameter of fixed mount）Direction overlaps or vertical or coincidence replaces with vertical, the setting of fixed mount
Can preferably for sealing joint strip provides supporting force, crossbeam can limit the deformation of sealing joint strip, prevent its displacement or deformation, and then
Improve voltage endurance capability.
Preferably：Described metal is aircraft aluminum.
Preferably：The a diameter of 5-200mm of described metallic framework, thickness is 1-35mm.
Preferably：The quantity of through hole and fixed mount is eight, is alternately distributed.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any one skilled in the art in the technical scope that the utility model is disclosed, the change that can be readily occurred in
Change or replace, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should be with described
Scope of the claims is defined.
