Description
Technical field
The utility model belongs to flange seal equipment technical field, is specifically a kind of flange gasket.
Background technology
The sealing principle of flange is extremely simple:Two sealing surfaces of bolt mutually squeeze flange gasket and form sealing.But
This also causes the destruction of sealing simultaneously.In order to keep sealing, huge bolt active force must be maintained.For this purpose, bolt will be done
Obtain bigger.And the bolt of bigger will match the nut of bigger, this, which means that, needs the bolt of diameter bigger to tighten nut
It creates conditions.Hardly realize, the diameter of bolt is bigger, and applicable flange will become bended, and only way is exactly to increase flange
Partial wall thickness.Whole device will need extremely large size and weight, this has become a specific question under paralic environment, because
It is the main problem that people must cause concern always for weight in this case.
The content of the invention
The utility model provides a kind of flange gasket to solve the problems, such as flange seal.
The utility model takes following technical scheme:A kind of flange gasket, including made of rubber elastic material first
Ring and the second ring, the first ring and the second ring are equipped with circular protrusions, circle compared with ring axis transverse direction wedgewise structure, the first ring middle part
Shape protrusion is external to be equipped with annular chuck, is equipped with the circular groove agreed with circular protrusions in the middle part of the second ring, circular groove bottom is set
There is an annular groove agreed with annular chuck, the first ring and the second ring are internally provided with annular stiffener inserts.
Further, annular stiffener inserts are equipped with gentle section and several harmonic wave sections, and gentle section is arranged on the first ring
Or second ring the relatively most thin position of wedge shape at, harmonic wave section is arranged at the other positions in annular stiffener inserts, harmonic wave
Section is equipped with multiple ripples, wherein each ripple has wave crest, the height of each wave crest is in the High definition by increased wedge structure
Direction on gradually increase.
Further, partition plate is equipped between adjacent ripple.
Further, gentle section is equipped with fracture.
Compared with prior art, the utility model two rings made of rubber elastic material, two rings are compared with ring
Axis is laterally formed in a wedge shaped pattern.Two rings only need to be rotated by two opposite directions, it is possible in an angle of flare
It spends on the position for 0 ° and continuously adjusts same position.And the position of maximum extension angle.The alignment error of flange misalignment can
To be sealed to compensate by using washer.When mounted it is prevented to be forced out from seal clearance to improve flange gasket
Robustness, be provided with metal ring stiffener inserts in two rings, whole robustness can be increased.
Description of the drawings
Fig. 1 is the utility model structure diagram;
Fig. 2 is the utility model sectional view;
Fig. 3 is annular stiffener inserts structure diagram;
1- flange gaskets in figure, the first rings of 2-, the second rings of 3-, 4- annular stiffener inserts, the gentle sections of 5-, 6- ripples, 7- wedges
Shape structure is with respect to thinnest part, and 8- wedge structures are with respect to thickness, 9- partition plates, 10- fractures.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
As shown in Figure 1, 2, a kind of flange gasket, including the first ring 2 made of rubber elastic material and the second ring 3,
Compared with ring axis transverse direction wedgewise structure, 2 middle part of the first ring is equipped with circular protrusions for one ring 2 and the second ring 3, outside circular protrusions
Equipped with annular chuck, 3 middle part of the second ring is equipped with the circular groove agreed with circular protrusions, and circular groove bottom is equipped with and annular snap
The annular groove that platform agrees with, the first ring 2 and the second ring 3 are internally provided with annular stiffener inserts 4.
Annular stiffener inserts 4 are equipped with gentle section 5 and several harmonic wave sections, and gentle section 5 is arranged on the first ring 2 or the second
At the wedge-shaped relatively most thin position of ring 3, harmonic wave section is arranged at the other positions in annular stiffener inserts 4, and harmonic wave section is set
There are multiple ripples 6, wherein each ripple 6 has wave crest, the height of each wave crest is in the High definition by increased wedge structure
Gradually increase on direction.As shown in figure 3, partition plate 9 is equipped between adjacent ripple 6.Gentle section 5 is equipped with fracture 10.
The utility model realizes three dimensional supporting frame(Annular stiffener inserts)It is integrated into the flange of annular reinforcing inserts
Washer.In view of waveform, annular stiffener inserts have waveform, which results in elasticity, but for the robustness of flange gasket
It is required that solid ring design.The three-dimensional bending surface of annular stiffener inserts makes flange gasket very resistance to compression and resistance to deformation.With wedge
High increase, the increase of wave height provide a kind of sandwich for flange gasket, to keep uniform surface-stable under a load
Property.
Annular stiffener inserts have gentle section in the region of the wedge shaped tip of respective rings, thus in the most narrow region of ring
Middle realization surface enhanced.In addition, waveform is preferably symmetrical compared with the central cross section of ring, so as in wedge-shaped circumferential development
In the reinforcement insert of stepless action is provided for ring.
The waveform of annular stiffener inserts is preferably adapted;To the wedge profile of ring.With what is extended in a wedge shaped pattern
The increase of the wave height of the annular reinforcement insert of waveform can adapt to the ring of the wedge-shaped form of flange gasket.The curve of waveform is long
Degree and height of curve can be selected according to the wedge height of ring.Harmonic wave preferably passes through the plane in the outer surface for being basically parallel to ring
The wave crest of middle orientation or hump are realized.In this case, harmonic wave is preferably from the formation flat between harmonic wave
Bottom surface extends.Bottom surface is preferably positioned to be basically parallel to the inner surface of ring.
Annular stiffener inserts can be manufactured by various metal materials.
Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art
Say, can still modify to the technical solution recorded in foregoing embodiments or to which part technical characteristic into
Row equivalent substitution, within the spirit and principle of the utility model, any modifications, equivalent replacements and improvements are made should all
It is included within the scope of protection of this utility model.
