Description
Technical field
It the utility model is related to seal fitting technical field, more particularly to a kind of sealing ring.
Background technology
Sealing ring is critically important for reciprocating dynamic seal device, and in general O-ring seal can not meet market
Demand, effect is not that apparent and service life is not grown, and is easily damaged, air-tightness is poor, and this brings inconvenience to production, prolongs
The production time has been missed, has reduced machine performance and production efficiency.Therefore, it is CN201836388U, specially in a Authorization Notice No.
The Chinese utility model patent of the entitled y-type seal ring of profit, it is affixed on sealing pair coupled face, no internal pressure by the lip of its opening
When, the contact of very little is only produced because of the deformation of procheilon, in the case of sealing, the every bit that is contacted with sealing medium
On have the normal pressure equal with pressure medium, so lip-shaped ring bottom will be axially compressed, lip by circumferential compression,
Contact and broaden with sealing surface, while contact stress increase, when internal pressure raises again, the distribution form and size of contact enter one
Step changes, and lip and sealing surface cooperation are closer, so sealing is more preferable than O-ring seal before, will be original common
Elastomeric material replaces with urethane rubber materials so that y-type seal ring resistant to hydrolysis, resistance to expansion, buckling is small, enhances using the longevity
Life, stabilizes sealing effectiveness, improves machine performance and production efficiency.However, carried out using above-mentioned y-type seal ring a large amount of reciprocal
After motion, the lip joining place of sealing ring easily occurs pullling tear phenomenon, and then influences its sealing effectiveness.
Utility model content
To overcome disadvantages mentioned above, the purpose of this utility model is to provide a kind of anti-tear and good sealing effect sealing
Circle.
In order to reach object above, the technical solution adopted in the utility model is：A kind of sealing ring, including acrylate rubber
Sealing ring body, outer seal lip and interior sealing lip made of glue or hydrogenated nitrile-butadiene rubber material, the sealing ring body top are set
There is outer seal lip and the interior sealing lip, V-type groove, the bottom land of the groove are formed between outer seal lip and the interior sealing lip
Rounding off；It is compound in the groove to be provided with methyl vinyl silicone rubber ring；The thickness of the interior sealing lip is more than external seal
The thickness of lip, and thickness difference between the two is 0.05mm.
The utility model in the compound increase methyl vinyl silicone rubber ring of V-type groove by that will improve outer seal lip and interior
Ductility when sealing lip stretches, and then prevent outer seal lip and interior sealing lip root from tearing problem.Simultaneously to outer seal lip
It is defined with the thickness of interior sealing lip, both balanced stressing conditions.
Preferably, the cross section of the methyl vinyl silicone rubber ring is crescent structure, bottom land of its thickness from groove
Gradually successively decrease to both sides, and anti-package structure is formed at the top of groove.By the setting of said structure, can maximumlly be lifted
The ductility of methyl vinyl silicone rubber ring, protects the root of outer seal lip and interior sealing lip, and then improves the anti-of its root
Tear ability.
It is as further improvement of the utility model, it is compound on the outer surface of sealing ring to be provided with polytetrafluoroethylene (PTFE) painting
Layer；The thickness of the polytetrafluorethylecoatings coatings is 0.1~1mm.By the self-lubricating effect of polytetrafluorethylecoatings coatings, sealing is improved
The anti-wear performance of circle, reduce resistance during friction, and then the sealing of lift-off seal circle.
Preferably, the outer seal lip is protruded and 158 ° of angle is formed with the outer surface of sealing ring body laterally；Institute
The surface for stating outer seal lip is the horizontal plane and inclined-plane being mutually linked, and the horizontal plane is located at the inner side of outer seal lip, described oblique
Downwards and its angle between horizontal plane is 14 °.Horizontal plane is contact surface during without internal pressure, and outer seal lip is outside when having internal pressure
Open, contact surface is extended to horizontal plane and inclined-plane, strengthens the sealing property of sealing ring.
Preferably, the interior sealing lip is provided with outside lug boss on the one side of sealing circle center, described convex
The cross section in the portion of rising is triangular structure, and the angle at the top of it is 60 degree, and the top rounding off.Pass through lug boss
Design, can greatly lift-off seal circle inner ring sealing property.

Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model
Define.
Referring to shown in accompanying drawing 1, Fig. 2, a kind of sealing ring in the present embodiment, including acrylate rubber or hydrogenated butyronitrile rubber
Sealing ring body 1, outer seal lip 2 and interior sealing lip 3 made of glue material, the top of sealing ring body 1 are provided with described outer close
