Problems solved by technology

[0003] When the oil pressure in the hydraulic cylinder is too high, the pressure difference on both sides of the sealing ring increases continuously, and the circumferential contact stress between the upper and lower lips of the Y-shaped structure and the coupling contact surface rises sharply, which intensifies the Y-shaped structure. The amount of wear and tear will cause edge damage of the sealing ring and reduce the service life of the sealing ring

Embodiment Construction

[0014] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0015] figure 1 It is a cross-sectional view of a Y-shaped sealing ring in an embodiment of the present invention; the Y-shaped sealing ring includes an annular body 1, and the annular body 1 is provided with a Y-shaped sealing structure on the side of the high-pressure oil, and the annular body 1 is not connected to the high-pressure oil. A wear-resistant ring 2 structure is added at one end, and the wear-resistant ring 2 and the annular body 1 are formed into one body through a vulcanization and gluing process.

[0016] The main material of the wear-resistant ring 2 added on the annular body 1 of the Y-shaped sealing ring mentioned in the prese...

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 ...
