Abstract
The invention discloses a Y-type sealing ring. The Y-type sealing ring comprises an annular body, wherein a Y-type sealing structure is arranged on one side, communicated with high-pressure oil, of the annular body; an abrasion-proof ring structure is additionally arranged on one end, not communicated with the high-pressure oil, of the annular body; and the abrasion-proof ring and the annular body are molded into a whole through a vulcanizing gluing process. The invention discloses the Y-type sealing ring, the Y-type sealing ring is unique in structural design, the abrasion-proof ring structure is additionally arranged on the annular body, and due to the structure, the abrasion resistance of the sealing ring is effectively improved and the service life of the sealing ring is improved; and meanwhile, due to the structure, an upper oil trapping area and a lower trapping area are formed by the sealing ring during a working process, so that abrasion losses of an upper lip and the lower lip of the sealing ring are effectively controlled, and the sealing performance is more excellent and the working state is more stable.
Description
Technical field
The present invention relates to a kind of y-type seal ring, relate in particular to that a kind of wear-resisting property is outstanding, working life lasting y-type seal ring, belong to the hydraulic fittings technical field.
Background technique
The cross section of y-type seal ring is the Y type, is a kind of typical lip-type packing.In the height in its cross section, wide ratio difference, can be divided into several classes such as wide type, narrow type, Yx type; Whether equate by the height of two lips, then can be divided into the universal contour lip y-type seal ring of axle, hole and not the axle of contour lip with y-type seal ring and hole y-type seal ring.Y-type seal ring relies on its lip limit of opening and sealing pair coupled face to fit.When without interior pressure, only the distortion because of procheilon produces very little contact, with on the every bit that sealing medium contacts the normal pressure that equates with pressure medium is arranged all, so lower lips will be subject to axial compression, and upper lip is subject to circumferential compression, contact with sealing surface and to broaden, contact stress increases simultaneously; When interior pressure raise again, the distribution form of contact and size further changed, and lip cooperates tightr with sealing surface, thus better tightness, " self-tightening " of Here it is y-type seal ring.Because this " self-tightening ", y-type seal ring can effectively seal the high pressure of 32MPa.
When the oil pressure in the oil hydraulic cylinder is too high, the pressure reduction of seal ring both sides constantly increases, and the circumferential contact stress between the upper and lower lip of y-type structure and the coupling surface of contact sharply rises, thus the wear extent of having aggravated y-type structure, make seal ring produce edge breakage phenomenon, the working life of having reduced seal ring.
Summary of the invention
For the demand, the invention provides a kind of y-type seal ring, set up a wear-resisting ring structure on this y-type seal ring, Effective Raise the wear-resisting property of seal ring; Simultaneously, this structure makes seal ring form in the course of the work upper and lower two pocketed oil districts, and the wear extent of seal ring is effectively controlled, and has promoted the working life of seal ring.
The present invention is a kind of y-type seal ring, this y-type seal ring comprises a ring body, ring body arranges Y type sealing configuration in logical high pressure oil one side, described ring body is set up the wear-resisting ring structure at non-logical high pressure oil one end, is integrated by sulfuration gummed technological forming between described wear-resisting ring and the ring body.
In a preferred embodiment of the present invention, the main material of described wear-resisting ring is teflon, can add quantitative graphite microparticles and nylon micro mist in preparation process, to improve elasticity and the self-enrichment energy of wear-resisting ring.
In a preferred embodiment of the present invention, the external diameter of described wear-resisting ring is 1.15-1.18 times of ring body external diameter, and its internal diameter is 0.9-0.92 times of ring body internal diameter.
In a preferred embodiment of the present invention, described wear-resisting ring can cooperate with the upper and lower lip generation in the Y type sealing configuration, can form upper and lower two pocketed oil districts therebetween, improves the sealing effect of seal ring comprehensively.
In a preferred embodiment of the present invention, described wear-resisting ring thickness is about 0.25-0.3 times of ring body thickness.
The present invention has disclosed a kind of y-type seal ring, and this y-type seal ring structural design is unique, sets up a wear-resisting ring structure on its ring body, this structure Effective Raise the wear-resisting property of seal ring, promoted working life of seal ring; Simultaneously, this structure makes seal ring form in the course of the work upper and lower two pocketed oil districts, and the wear extent of the upper and lower lip of seal ring is effectively controlled, and sealability is better, and working state is more steady.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is the sectional drawing of embodiment of the invention y-type seal ring;
The mark of each parts is as follows in the accompanying drawing: 1, ring body, 2, wear-resisting ring.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
Fig. 1 is the sectional drawing of embodiment of the invention y-type seal ring; This y-type seal ring comprises a ring body 1, ring body 1 arranges Y type sealing configuration in logical high pressure oil one side, described ring body 1 is set up wear-resisting ring 2 structures at non-logical high pressure oil one end, is integrated by sulfuration gummed technological forming between described wear-resisting ring 2 and the ring body 1.
The main material of the wear-resisting ring 2 of setting up on the ring body 1 of the y-type seal ring that the present invention mentions is teflon, can add quantitative graphite microparticles and nylon micro mist in preparation process, to improve elasticity and the self-enrichment energy of wear-resisting ring; The content of teflon is controlled at more than 80%, with the wear-resisting property of guaranteeing that wear-resisting ring 2 is good.
The external diameter of wear-resisting ring 2 is 1.15-1.18 times of ring body external diameter, and its internal diameter is 0.9-0.92 times of ring body internal diameter, and wear-resisting ring 2 thickness are about 0.25-0.3 times of ring body 1 thickness; This structural design forms upper and lower two pocketed oil districts therebetween so that wear-resisting ring 2 can cooperate with the upper and lower lip generation in the Y type sealing configuration, improves the sealing effect of seal ring comprehensively; Simultaneously, also effectively reduce the contact stress between upper and lower lip and the coupling surface of contact, reduced the wear extent of Y type sealing configuration, promoted the working life of seal ring.
