Abstract
The utility model relates to a kind of y-type seal ring, comprise seal ring body, the upper end of described seal ring body is towards being outside equipped with outer lip, being provided with epipharynx inwardly, tiltedly " U " type passage is formed between outer lip and epipharynx, the height of described outer lip is greater than the height of epipharynx, and the below of described tiltedly " U " type passage is provided with " V " type groove; Described seal ring body interior offers cavity along its circumference.By being provided with " V " type groove below oblique " U " type passage of seal ring, make the liquid remained will be full of " V " type groove, form a special seal area, even if epipharynx is impaired because repeatedly rubbing, seal action is still played in above-mentioned special seal area, thus substantially increases the sealability of y-type seal ring; By offering cavity in seal ring body interior, the pressure that seal ring bears effectively can be unloaded.
Description
Technical field
The utility model relates to a kind of seal ring, particularly relates to a kind of not only high temperature resistant but also easily bears the seal ring of distortion.
Background technique
Existing seal ring is of a great variety, and conventional has O type circle, Y-shaped ring, V-type combination seal.O type circle is generally used for static seal, and Y-shaped ring and V-type combination seal are generally used for motive sealing.V-shaped seal ring is a kind of elastic rubber sealing ring of axial action, as rotating shaft without means of press seals.Sealing lip has good mobility and adaptability, can the large tolerance of compensate for slower and augular offset, and internal grease or fluid can be prevented to external leakage, also can prevent extraneous dabbling or the intrusion of dust.U-shaped circle is usually used in manufacturing the reciprocation sealing in hydraulic system.Be widely used in the sealing of oil hydraulic cylinder in engineering machinery.O RunddichtringO is mainly used in static seal and reciprocating movement sealing.During for rotary movement seal, be only limitted to low speed rotary seal.Square RunddichtringO is generally arranged in groove that cylindrical or inner circle upper section are rectangle and seals.Y-type seal ring is widely used in reciprocating motion sealing device.
Y-type seal ring of the prior art adopts monolateral sealing, although its sealability, withstand voltage properties and working life substantially exceed O RunddichtringO, but when doing sealing use in precise hydraulic oil cylinder, its single sealing lip contacts for a long time repeatedly through piston rod, even if slight friction is impaired, also sealability will be caused to reduce thus cause hydraulic oil to be revealed, affect the normal operation of hydraulic jack, and the working pressure≤32Mpa of existing Y RunddichtringO, cannot be applicable to the precise hydraulic oil cylinder that working pressure is higher.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of good sealing effect, improves the seal ring in working life.
The utility model is achieved through the following technical solutions:
A kind of y-type seal ring, comprise seal ring body, the upper end of described seal ring body is towards being outside equipped with outer lip, being provided with epipharynx inwardly, tiltedly " U " type passage is formed between outer lip and epipharynx, the height of described outer lip is greater than the height of epipharynx, and the below of described tiltedly " U " type passage is provided with " V " type groove; Described seal ring body interior offers cavity along its circumference.
As optimal technical scheme of the present utility model, the top outer side of described y-type seal ring body bottom dual-side and y-type seal ring body outer lip and epipharynx, is respectively equipped with chamfering.
As optimal technical scheme of the present utility model, described cavity is circular, and its diameter is 1/4th of seal ring body width.
As optimal technical scheme of the present utility model, described outer lip is than interior bilabial 1-3mm.
As optimal technical scheme of the present utility model, described seal ring body adopts polyurethane material to make.
Compared with prior art, the beneficial effects of the utility model are: the utility model by being provided with " V " type groove below oblique " U " type passage of seal ring, make the liquid remained will be full of " V " type groove, form a special seal area, even if epipharynx is impaired because repeatedly rubbing, seal action is still played in above-mentioned special seal area, thus substantially increases the sealability of y-type seal ring; By offering cavity in seal ring body interior, the pressure that seal ring bears effectively can be unloaded.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-seal ring body; 2-cavity; 3-" V " type groove; 10-outer lip; 11-epipharynx; 12-is " U " type passage tiltedly; 13-chamfering.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of y-type seal ring, comprise seal ring body 1, the upper end of described seal ring body 1 is towards being outside equipped with outer lip 10, being provided with epipharynx 11 inwardly, tiltedly " U " type passage 12 is formed between outer lip 10 and epipharynx 11, the height of described outer lip 10 is greater than the height of epipharynx 11, and the below of described tiltedly " U " type passage 12 is provided with " V " type groove 3; Described seal ring body 1 inside offers cavity 2 along its circumference; The top outer side of described y-type seal ring body bottom dual-side and y-type seal ring body outer lip 10 and epipharynx 11, is respectively equipped with chamfering 13.
The lip limit that y-shaped ring relies on it to open is affixed on sealing pair coupled face.During without interior pressure, only produce very little contact because of the distortion of procheilon.When sealing, the every bit contacted with sealing medium all has the normal pressure equal with pressure medium, so will be subject to axial compression bottom lip circle, lip will be subject to circumference compression, contact broaden with sealing surface, and contact stress increases simultaneously.When interior pressure raises again, distribution form and the size of contact change further, and lip coordinates tightr with sealing surface, so better tightness, and " self-tightening " of Here it is Y shape circle.
Described cavity 2 is circular, and its diameter is 1/4th of seal ring body 1 width, described outer lip 10 1-3mm higher than epipharynx 11.
Described seal ring body 1 adopts polyurethane material to make, lightweight, reduces load; The water-proof performance that tool is excellent, insulation, waterproof unite two into one.
In sum, the utility model by being provided with " V " type groove below oblique " U " type passage of seal ring, make the liquid remained will be full of " V " type groove, form a special seal area, even if epipharynx is impaired because repeatedly rubbing, seal action is still played in above-mentioned special seal area, thus substantially increases the sealability of y-type seal ring; By offering cavity in seal ring body interior, the pressure that seal ring bears effectively can be unloaded.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
