Abstract

The utility model relates to a Y-shaped seal ring. A section of the Y-shaped seal ring is Y-shaped; the Y-shaped seal ring comprises a seal ring body and an outer lip and an inner lip which are arranged on the seal ring body, wherein the thickness of the outer lip is greater than that of the inner lip. The Y-shaped seal ring has the benefits that the seal ring made of a polyurethane material is good in wear-resistant effect and small in compressive deformation; the thicknesses of the outer lip and the inner lip are different, so that the Y-shaped seal ring is good in sealing effect; and the sealing effect of a sealing element at low pressure is improved with the adoption of auxiliary lips.

Description

A kind of y-shaped ring

Technical field

The utility model relates to the seal ring technical field, especially relates to a kind of y-shaped ring.

Background technique

In the hydraulic transmission process, particularly in the static seal of reciprocating movement oil cylinder, most of structures are the form of " 1 O shape circle adds 1 back-up ring " or are single lip Y shape circle at present.But the form of " 1 O shape circle add 1 back-up ring " often has leakage situation in high pressure, though and single lip Y shape circle is fine in high pressure conditions lower seal performance, it leakage but often occurs in low pressure, normally carry out thereby influenced production work.

Therefore, a kind of simple in structure, the appearance of y-shaped ring with excellent sealing effect is necessary.

The model utility content

The utility model is to provide a kind of simple in structure for solving the problems of the technologies described above, and has the y-shaped ring of excellent sealing effect.

The technical problem that the utility model solves realizes by the following technical solutions:

A kind of y-shaped ring, its cross section is Y shape, comprises the seal ring body, and is arranged at outer lip and epipharynx on the described seal ring body, wherein, the honest and kind thickness greater than described epipharynx of described outer lip is provided with secondary lip in the both sides of described seal ring body.

As optimized technical scheme, between described outer lip and epipharynx, be provided with v-depression.

As optimized technical scheme, the outside, top at described outer lip and epipharynx is respectively arranged with chamfering.

As optimized technical scheme, the material of described y-shaped ring is polyurethane material.

The beneficial effect that the utlity model has is: the seal ring that (1) adopts polyurethane material to make, and wear-resisting effective, compressive strain is little;

(2) thickness of outer lip and epipharynx is different, good sealing effect;

(3) raising of secondary lip Sealing sealing effect when low-pressure.

Description of drawings

Fig. 1 is the utility model: a kind of structural representation of y-shaped ring;

Fig. 2 is the utility model: a kind of cross-sectional view of y-shaped ring:

Wherein: 1-seal ring body, 2-outer lip, 3-epipharynx, 4-groove, the secondary lip of 5-.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Shown in Fig. 1-2, a kind of y-shaped ring, the employing polyurethane material is made, its cross section is Y shape, comprises seal ring body 1 and is arranged at outer lip 2 and epipharynx 3 on the described seal ring body 1, wherein, the honest and kind thickness greater than described epipharynx 3 of described outer lip 2, be provided with v-depression 4 between described outer lip 2 and epipharynx 3, the outside, top at described outer lip 2 and epipharynx 3 is respectively arranged with chamfering.

In order to reach better sealing effect, be provided with secondary lip 5 in the both sides of described seal ring body 1.More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
