Background technology
Ring flange is the metal parts that a kind of pipeline is connected with each other with pipeline, and it is related to essentially all of pipeline engineering
With the field of mechanical connection, there is the characteristics of high leakproofness, high stability, but because pipeline air pressure inside changes, make its internal production
Give birth to axial force and cause bolt to be stretched, flange sealing surface can move along the direction separated each other, make sealing between flange
It can reduce, usually can be inserted in seal in flange connections, and conventional seal is based on thin disc coupons, but its sealing master
The rebound effect after the extruding and separation of packing ring is relied on, easily occurs aged deterioration after long-time use, and without preferable
Adsorptivity, easily accumulate internal moisture, seal is in dampness for a long time and easily accelerate seal aging, so as to
Have influence on the sealing of inner seal.
The content of the invention
The purpose of this utility model is to provide a kind of high vacuum flange seal, to solve to propose in above-mentioned background technology
The problem of.
To achieve the above object, the utility model provides following technical scheme：A kind of high vacuum flange seal, including it is close
Seal, the both sides of the sealing ring are fixedly connected with first flange disk and second flange disk, the fastening spiral shell by clamping bolt
The end thread of bolt is connected with fastening nut, and flange is provided with the outside of the sealing ring, and the middle part of the sealing ring, which is fixed, to be connected
Contact ring is connected to, the inside of the sealing ring is fixedly connected with interior seal, and the upper surface of the sealing ring is bonded with salient point annulus,
The surrounding of the contact ring is provided with bolt hole, and through hole is provided with the middle part of the interior seal.
Preferably, the outside of the sealing ring is cirque structure, and the inner side of the sealing ring is truncated cone-shaped structure.
Preferably, the material of the flange is natural rubber, and the thickness of the flange is less than the thickness of contact ring.
Preferably, the material of contact ring and the salient point annulus is fluorubber.
Preferably, the thickness of the salient point annulus is more than the half of contact ring thickness, and the salient point annulus is along center of circle direction
Equidistantly distributed.
Preferably, the material of the interior seal is silica gel, and the interior seal passes through viscous on the inside of polyurethane AB glue and contact ring
Connect.
Preferably, the external diameter of the contact ring is equal with the external diameter of first flange disk.
Preferably, the flange is brought into close contact interior with second flange disk in the outside of first flange disk, the interior seal
Chamber is brought into close contact.
Compared with prior art, the beneficial effects of the utility model are：The utility model device uses special interior round platform
Cylindrical ring structure, add to the area in sealing contact between two ring flanges, improve sealing effectiveness, and the flange of natural rubber
Sealing function is then folded to first flange in outside, salient point annulus can be then prevented because stretching causes flange seal separation excessive
And cause the state of seal break-off, and carrying out ultimate attainment sealing using high salient point, three rings reinforce sealing effectiveness, and fluorubber material
Contact ring can then effectively improve the low characteristic of its corrosion-resistant, resistance to fuel oil, media-resistant, buckling, and seal not only can be by interior in silica gel
Portion seals to second flange disk, and adsorbable internal moisture and medium, ensure that dry cleansing in pipeline, whole close so as to improve
The service life of seal.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-3 are referred to, the utility model provides a kind of technical scheme：A kind of high vacuum flange seal, including sealing
Circle 3, the both sides of the sealing ring 3 are fixedly connected with first flange disk 1 and second flange disk 5, the fastening by clamping bolt 2
The end thread of bolt 2, which is connected with, fastens nut 4, and the outside of the sealing ring 3 is provided with flange 6, the middle part of the sealing ring 3
Contact ring 9 is fixedly connected with, the inside of the sealing ring 3 is fixedly connected with interior seal 10, the upper surface bonding of the sealing ring 3
There is salient point annulus 7, the surrounding of the contact ring 9 is provided with bolt hole 8, and the middle part of the interior seal 10 is provided with through hole 11.
The outside of the sealing ring 3 is cirque structure, and the inner side of the sealing ring 3 is truncated cone-shaped structure, the flange 6
Material be natural rubber, the thickness of the flange 6 is less than the thickness of contact ring 9, the material of the contact ring 9 and salient point annulus 7
Matter is fluorubber, and the thickness of the salient point annulus 7 is more than the half of the thickness of contact ring 9, and the salient point annulus 7 is along center of circle direction
Equidistantly distributed, the material of the interior seal 10 is silica gel, and the interior seal 10 is viscous by polyurethane AB glue and the inner side of contact ring 9
Connect, the external diameter of the contact ring 9 is equal with the external diameter of first flange disk 1, and the flange 6 is brought into close contact in first flange disk 1
Outside, the interior seal 10 and the inner chamber of second flange disk 5 are brought into close contact.
Operation principle：When using this high vacuum flange seal when, first by sealing ring 3 just putting with first flange disk 1 and
Between second flange disk 5, by clamping bolt 2 by first flange disk 1 pass through sealing ring 3 in bolt hole 8 after with second flange
Disk 5 is connected, and end fastens nut 4 and fixed, and sealing ring 3 is extruded after the fastening of fixing bolt 2, forms the initial true of inside
Empty sealing state, and the inner chamber of second flange disk 5 is stretched into interior seal 10 and is tightly invested on madial wall, flange 6 then tightly invests the first method
The blue lateral wall of disk 1, when axial force stretches clamping bolt 2, there is relative separation in sealing surface, and the now meeting of contact ring 9 resilience continues
