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

[0001] The invention relates to a Y-shaped sealing ring, in particular to a Y-shaped sealing ring with outstanding wear resistance and long service life, and belongs to the technical field of hydraulic fittings. Background technique

[0002] The section of the Y-shaped sealing ring is Y-shaped, which is a typical lip-shaped sealing ring. According to the ratio of the height and width of the cross-section, it can be divided into wide type, narrow type, Yx type, etc.; according to whether the height of the two lips is equal, it can be divided into the shaft and hole common type equal-height lip Y-type seal Y-rings for shafts with rings and unequal lips and Y-rings for bores. The Y-shaped sealing ring relies on its open lip to fit the sealing pair coupling surface. When there is no internal pressure, only a small contact pressure is generated due to the deformation of the tip of the lip, and every point in contact with the sealing medium has a normal pressure ...
