Description
Technical field
The present invention relates to a kind of sealing ring, more particularly to a kind of double hardness sealing rings.
Background technology
In general, sealing ring needs to meet following technical conditions：High resilience and resilience；It is strong with appropriate machinery
Degree, including tensile strength, elongation and tearing toughness etc.；Stable performance, it is not easy to be swelled in media as well, thermal pinch is (burnt
Ear effect) it is small；Easy processing is molded, and can keep accurate size；Do not corrode contact surface, not pollution medium etc..
Sealing ring of the prior art has the following disadvantages：Elastomeric material of most of sealing ring only with single hardness
Make, it is single hard when the structure position for needing to seal needs the elastomeric seal using different hardness at multiple sealing surfaces
The sealing ring of degree can not meet demand；The sealing ring sealing effectiveness of single hardness is poor, is unable to reach required sealing effectiveness.
The content of the invention
For weak point present in above-mentioned technology, it is an object of the invention to provide a kind of double hardness sealing rings, it is ensured that
When needing the elastomer using different hardness to seal the sealing surface of different hardness demand, demand disclosure satisfy that and can
Further improve sealing effectiveness.
In order to realize according to object of the present invention and other advantages, there is provided a kind of double hardness sealing rings, its feature
It is, including：

First sealing lip of raised ring-type vertically；And
Second seal of ring-type, it includes the second pedestal of ring-type and from the axial end of second pedestal
Second sealing lip of raised ring-type vertically,
Wherein, first sealing lip sets with the second sealing lip homonymy and is mutually separated with certain distance, and described first
Seal has different hardness, the outside of the medial plane of second sealing lip and second pedestal from the second seal
Plane is flush, and the inner side plane of second sealing lip and the inner side plane of second pedestal apart have a certain distance,
So that the inner side of second seal has a stage portion, so that the radial direction that second seal has L-shaped is cut
Face, first seal are embedded in the stage portion of second seal, and first seal is set with the second seal
Concentric ring is set to, first seal integrally merges with the second seal in the stage portion.
Preferably, the medial plane of the medial plane of first sealing lip and first pedestal apart has certain
Distance, the inner side plane of first sealing lip and the inner side plane of first pedestal apart have a certain distance, so that
Obtaining first seal has the radial section of convex shape.
Preferably, first sealing lip apart has a certain distance fluted so as to be formed with the second sealing lip.
Preferably, the guiding that the medial plane of second sealing lip is arranged to form an angle with axial plane is oblique
Face, the angle is set as α, then there are 0 °≤α≤80 °.
Preferably, first seal is made up of elastomeric material of the shore hardness by 40 degree to 90 degree, and described second
Seal is made up of elastomeric material of the shore hardness by 0 degree to 60 degree.
Preferably, first seal is made up of elastomeric material of the shore hardness by 0 degree to 60 degree, and described second is close

Operation principle：When double hardness sealing rings 100 according to the present invention are formed with structure to be sealed to be sealed, the first sealing
The sealing lip 122 of lip 112 and second is inconsistent with face to be sealed respectively and is oppressed and produces deformation, due to the first sealing lip
112 and second sealing lip 122 apart have a certain distance so as to form fluted 130 so that the first sealing lip 112 and second close
Envelope lip 122 can have certain deformation space when being squeezed deformation, so as to obtain better seal effect, further, since
First seal 110 has different hardness from the second seal 120, can meet the structure to be sealed of different hardness requirement
Demand.
Number of devices and treatment scale described herein are the explanations for simplifying the present invention.To the present invention application,
Modifications and variations will be readily apparent to persons skilled in the art.
According to the present invention, as described above, it is possible to obtain following beneficial effect：
1. because the first seal 110 includes the first pedestal 111 of ring-type and the axial end from the first pedestal 112
On raised vertically ring-type the first sealing lip 112, the second seal 110 includes the second pedestal 121 of ring-type and from the
Second sealing lip 122 of ring-type raised vertically on the axial end of two pedestals 121, so as to position shape to be sealed
Into double-layer sealing structure, sealing effectiveness is greatly improved；
2. because the first sealing lip 112 is set with the homonymy of the second sealing lip 122 and is mutually separated with certain distance, the first seal
110 have different hardness from the second seal 120, so as to meet structure position that needs the seal need at multiple sealing surfaces
The demand of the elastomeric seal of different hardness is used, while the structure with different sealing changing firmness requirements is produced preferably close
Seal effect；
3. it is embedded at due to the first seal 110 in the stage portion of second seal 120, the first seal 110 and second
Seal 120 is arranged to concentric ring, and the first seal 110 is integrally merged in stage portion 121a with the second seal 120, made
Between the first seal 110 and the second seal 120 will not gas leakage, so as to further improving sealing effectiveness；
4. because the medial plane of the first sealing lip 112 and the medial plane of the first pedestal 111 apart have a certain distance,
The inner side plane of first sealing lip 112 and the inner side plane of the first pedestal 111 apart have a certain distance, so that first is close
Sealing body 110 has a radial section of convex shape, the first sealing lip 112 and the second sealing lip 122 apart have a certain distance so that
Form fluted 130 so that when double hardness sealing rings based on the present invention are in sealing, the first sealing lip 112 with
Second sealing lip 122 can have certain deformation space when being squeezed, so as to obtain better seal effect；
5. because the medial plane of the second sealing lip 122 is arranged to the lead-in chamfered that is formed an angle with axial plane
122a, lead-in chamfered 122a can cause double hardness sealings when this pair of hardness sealing ring 100 is engaged with structure to be sealed
Circle 100 is rapid and close with respective outer side edges to be sealed.
Although embodiment of the present invention is disclosed as above, it is not limited in listed fortune in specification and embodiment
With it can be applied to various suitable the field of the invention completely, can be easily real for those skilled in the art
Now other modification, therefore under the universal limited without departing substantially from claim and equivalency range, the present invention is not limited to
Specific details and shown here as the legend with description.
