Description
Technical field
The utility model relates to seal ring technical field, refers more particularly to a kind of y-type seal ring.
Background technique
Seal ring is very important for reciprocating dynamic seal device, and general O RunddichtringO can not meet the demand in market, effect be not clearly and working life not long, easily damage, this has brought inconvenience to production, has incured loss through delay the production time, has reduced machine performance and manufacturing efficiency.
Y-shaped ring relies on its lip limit of opening to be affixed on sealing pair coupled face.During without interior pressure, only the distortion because of procheilon produces very little contact.The in the situation that of sealing, on the every bit contacting with sealing medium, all there is the normal pressure equating with pressure medium, so lip circle bottom will be subject to axial compression, lip is subject to circumferential compression, contacts and broadens with sealing surface, contact stress increases simultaneously.When interior pressure raises again, the distribution form of contact and size further change, and lip coordinates tightr with sealing surface, thus better tightness, " self-tightening " of Here it is Y shape circle.Due to this self-tightening, a Y shape circle can effectively seal the high pressure of 32MPa.
Chinese patent 201220297435.3 discloses a kind of cylinder piston seal ring, comprises seal ring body, it is characterized in that, the cross section of described cylinder piston seal ring is " Y " shape, and one end of described seal ring body is provided with two diaphragm seals.This model utility, by one end of seal ring body being arranged to two diaphragm seals, in piston movement process, reduces the generation of gas leak phenomenon, increases work efficiency.But the wear-resisting weak effect of this model utility, diaphragm seal compression is yielding, and under low pressure sealing effect is poor, and working life is short.
Chinese patent 201220467860.2 discloses a kind of y-shaped ring, its cross section is Y shape, comprise seal ring body, and be arranged at outer lip and the epipharynx on described seal ring body, it is characterized in that, the honest and kind thickness that is greater than described epipharynx of described outer lip, is provided with secondary lip in the both sides of described seal ring body.The seal ring that this model utility adopts polyurethane material to make, wear-resisting effective, compressive strain is little; The thickness of outer lip and epipharynx is different, good sealing effect; Secondary lip has improved Sealing sealing effect when low-pressure.But the situation that this model utility easily leaks air, seal not thorough, sealability and the working life of having reduced rubber seal.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of y-type seal ring, and good sealing effect compresses indeformablely, air tight, and wear-resisting property is good, long service life.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of y-type seal ring, its cross section is Y shape, comprise seal ring body, it is characterized in that, described seal ring body is provided with outer lip and epipharynx, and the height of described epipharynx is higher than the height of described outer lip, described seal ring body bottom working surface is provided with interior secondary lip, the non-working surface of described seal ring body is provided with outer secondary lip, and described epipharynx working surface compacting forms texture structure layer, and the angular range of described epipharynx and outer lip is 30 °-50 °.
Preferably, the angular range of described epipharynx and outer lip is 33 °.
Preferably, the angular range of described epipharynx and outer lip is 42 °.
Preferably, described texture structure layer is ripple struction layer.
Preferably, the thickness of described epipharynx is greater than the thickness of described outer lip.
Advantage of the present utility model is as follows:
The height of the utility model epipharynx is higher than the height of outer lip, the thickness of epipharynx is greater than the thickness of outer lip, the compacting of epipharynx working surface forms texture structure layer, fit tightly with sealing medium, improved Sealing sealing effect when low-pressure, without gas leak phenomenon, compressed indeformable, wear-resisting property is good, long service life.
