Abstract
The utility model discloses a kind of y-shaped rings, it includes sealing ring ontology, it is provided with outer seal lip and interior sealing lip at the top of the sealing ring ontology, forms concave-curve opening between the outer seal lip and interior sealing lip, the height of the interior sealing lip is more than the height of the outer seal lip；There is at least one interior sealing pair lip on the madial wall of the interior sealing lip, there is at least one external seal pair lip on the lateral wall of the outer seal lip；Circumferentially equidistant in the lower inner wall of the sealing ring ontology to be equipped with several boss, the bottom surface of the boss is concordant with the bottom surface of sealing ring ontology.The y-shaped ring sealing effect of the utility model is good, and wear-resisting property is good, can reduce overturning, distortion, deformation phenomena such as generation.
Description
Technical field
The utility model is related to a kind of y-shaped rings, belong to field of rubber technology.
Background technology
The section of y-shaped ring is in Y types, is that a kind of typical lip-type packing is widely used in liquid because its sealing effect is good
Means of press seals.When the oil pressure in hydraulic cylinder is excessively high, the pressure difference of sealing ring both sides constantly increases, the inside and outside lip of Y-shaped structure with couple
Circumferential contact stress between contact surface steeply rises, to exacerbate deformation, the abrasion of Y-shaped structure so that under sealing effect
Drop, shortens service life, Shortcomings.
Utility model content
Against the above deficiency, the utility model provides a kind of y-shaped ring.
Technical solution used by the utility model is：
A kind of y-shaped ring comprising sealing ring ontology is provided with outer seal lip and interior at the top of the sealing ring ontology
Sealing lip, forms concave-curve opening between the outer seal lip and interior sealing lip, the height of the interior sealing lip is more than outside described
The height of sealing lip；There is at least one interior sealing pair lip, the outside of the outer seal lip on the madial wall of the interior sealing lip
There is at least one external seal pair lip on wall；It is circumferentially equidistant in the lower inner wall of the sealing ring ontology to be equipped with several boss, institute
The bottom surface for stating boss is concordant with the bottom surface of sealing ring ontology.
Further, the sealing ring body surface is provided with polytetrafluorethylecoatings coatings.
The utility model has the advantage of：The y-shaped ring sealing effect of the utility model is good, and wear-resisting property is good, can be with
The generation for phenomena such as reducing overturning, distortion, deformation.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Embodiment：
As shown in Figure 1, a kind of y-shaped ring comprising sealing ring ontology (1) is set at the top of the sealing ring ontology (1)
It is equipped with outer seal lip (2) and interior sealing lip (3), forms concave-curve opening between the outer seal lip (2) and interior sealing lip (3)
(4), the height of the interior sealing lip (3) is more than the height of the outer seal lip (2)；On the madial wall of the interior sealing lip (3)
Tool is there are one interior sealing pair lip (5), and there are one external seal pair lips (6) for tool on the lateral wall of the outer seal lip (2)；The sealing
It encloses circumferentially equidistant equipped with several boss (7), bottom surface and the sealing ring sheet of the boss (7) in the lower inner wall of ontology (1)
The bottom surface of body (1) is concordant.
Further, sealing ring ontology (1) surface is provided with polytetrafluorethylecoatings coatings (not shown).
The y-shaped ring sealing effect of the utility model is good, and wear-resisting property is good, and it is existing can to reduce overturning, distortion, deformation etc.
The generation of elephant.
The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art
For personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these are improved and profit
Decorations are also considered as the scope of protection of the utility model.
