Description
Technical field
The present invention relates to the technical field for mechanically connecting flange seal, specially a kind of high vacuum flange seal.
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
It is an object of the invention to provide a kind of high vacuum flange seal, is asked with solve to propose in above-mentioned background technology
Topic.
To achieve the above object, the present invention provides following technical scheme：A kind of high vacuum flange seal, including sealing
Circle, the both sides of the sealing ring are fixedly connected with first flange disk and second flange disk, the clamping bolt by clamping bolt
End thread be connected with fastening nut, flange is provided with the outside of the sealing ring, is fixedly connected in the middle part of the sealing ring
There is contact ring, 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, institute
The surrounding for stating 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 invention are as follows：The invention device uses special interior round platform outer toroid knot
Structure, add to the area in sealing contact between two ring flanges, improve sealing effectiveness, and the flange of natural rubber is then in outside
Sealing function is folded to first flange, salient point annulus can be then prevented because stretching causes flange seal separation excessively to cause close
The state destroyed is sealed, ultimate attainment sealing is carried out using high salient point, three rings reinforce sealing effectiveness, and the contact ring of fluorubber material is then
The low characteristic of its corrosion-resistant, resistance to fuel oil, media-resistant, buckling can be effectively improved, and seal not only can be by inside to second in silica gel
Flangeseal, and adsorbable internal moisture and medium, ensure that dry cleansing in pipeline, so as to improve making for whole sealing ring
Use the life-span.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Fig. 1-3 are referred to, the present invention provides a kind of technical scheme：A kind of high vacuum flange seal, including sealing ring 3,
The both sides of the sealing ring 3 are fixedly connected with first flange disk 1 and second flange disk 5, the clamping bolt by clamping bolt 2
2 end thread, which is connected with, fastens nut 4, and the outside of the sealing ring 3 is provided with flange 6, and the middle part of the sealing ring 3 is fixed
It is connected with contact ring 9, the inside of the sealing ring 3 is fixedly connected with interior seal 10, and the upper surface of the sealing ring 3 is bonded with convex
Point annulus 7, the surrounding of the contact ring 9 are 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
Sealed, when beyond resilience amplitude, then salient point annulus 7 will carry out ultimate attainment sealing function instead of contact ring 9, when going out in pipeline
During existing other media, such as water, impurity material, the interior seal 10 of silica gel material can then carry out suction-operated, make after removing impurity
Internal environment cleans, so as to improve the service life of sealing ring 3.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of changes, modification can be carried out to these embodiments, replace without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
