Abstract
The invention relates to the technical field of seal rings, and discloses a Y-type seal ring. The section of the Y-type seal ring is in a Y shape, the Y-type seal ring comprises a seal ring body, an outer lip and an inner lip are arranged on the seal ring body, the height of the inner lip is larger than that of the outer lip, an inner auxiliary lip is arranged on the working face at the bottom end of the seal ring body, an outer auxiliary lip is arranged on the non-working face of the seal ring body, the working face of the inner lip is pressed to form a texture structure layer, and the included angle between the inner lip and the outer lip is 30 degrees to 50 degrees. The height and the thickness of the inner tip are larger than those of the outer lip, and the texture structure layer is formed by pressing the working face of the inner lip and tightly attached to sealing media, so that the sealing effect of the seal part at low pressure is improved, air leakage is avoided, deformation is avoided in the compression mode, and the Y-type seal ring is high in abrasion resistance and long in service life.
Description
Technical field
The present invention relates to seal ring technical field, refer 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 because the distortion 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.In the time that 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 invention, 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 invention, 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 invention 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 in the time of low-pressure.But the situation that this invention easily leaks air, seal not thorough, sealability and the working life of having reduced rubber seal.
Summary of the invention
Technical problem to be solved by this invention 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 present invention 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 invention is as follows:
The height of epipharynx of the present invention 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, improve Sealing sealing effect in the time of low-pressure, without gas leak phenomenon, compressed indeformable, wear-resisting property is good, long service life.
