Abstract
The utility model relates to a sealing element, in particular to a seal ring for a plunger type oil gas cylinder. The seal ring for the plunger type oil gas cylinder comprises a sealing lip arranged on the annular inner surface of the seal ring and in interference fit with a plunger and an outer circular portion, wherein the outer circular portion of the seal ring is provided with at least one sealing rib in interference fit with the slot wall of a cylinder body. The seal ring for the plunger type oil gas cylinder is simple in structure and has a good sealing effect, and normal operation of the plunger type oil gas cylinder is guaranteed.
Description
Technical field
The utility model relates to a kind of Sealing, especially a kind of plunger type oil gas cylinder seal ring.
Background technique
the hydropneumatic oil cylinder, cylinder is at automobile, engineering machinery, agricultural machinery, each field of the industry equipments such as lathe obtains extensively anti-application already, but leakage of oil in using process, the frequent generation of gas leakage problem, perplexing for a long time the normal use of oil cylinder and cylinder always, its main cause is that the plunger sealing washer weak effect causes, at present, existing plunger sealing washer is generally y-type seal ring, the sealing effect that the direct hole slot with the installation seal ring of y-type seal ring is faced contacting point directly is poor, thereby cause the sealing effect of y-type seal ring poor, cause oil cylinder, cylinder produces pressure release or unloading.
The model utility content
The purpose of this utility model is to overcome the above-mentioned defect that exists in prior art, has proposed a kind of plunger type oil gas cylinder seal ring, and it is simple in structure, and good sealing effect has guaranteed the normal operation of plunger type oil gas cylinder.
The utility model is to adopt following technological scheme to realize: a kind of plunger type oil gas cylinder seal ring, comprise be arranged on the seal ring annular inner surface be sealing lip and the cylindrical section of interference fit with plunger, wherein, the cylindrical section of described seal ring is provided with at least one and is the sealed muscle of interference fit with the cylinder body cell wall.
In the utility model, the sectional shape of described sealed muscle can be semicircle, arc, triangle or other shapes.
The beneficial effects of the utility model are: by the cylindrical section at seal ring, sealed muscle is set, that has improved that traditional Y shape pillar plug sealing ring periphery directly contacts with hole slot faces place's sealing effect directly, played steady and the sealing double action, improve the sealing effect of y-type seal ring, guaranteed the normal operation of plunger type oil gas cylinder.
Description of drawings
Fig. 1 is sectional view of the present utility model.
In figure: 1 sealing lip; 2 first sealed muscles; 3 second sealed muscles; 4 oil cylinder housings; 5 plunger axis.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the sectional shape of this y-type seal ring is the Y type, comprises the sealing lip 1 and the cylindrical section that are arranged on the seal ring annular inner surface, and sealing lip 1 is interference fit with plunger axis 5, thereby makes sealing lip 1 play seal action.The cylindrical section of seal ring is provided with the two seals muscle, respectively first sealed muscle 2 and second sealed muscle 3, the sectional shape semicircular in shape of sealed muscle 3, twice semicircle sealed muscle tightly is attached on the seat cell wall of cylinder body 4, play the effect of steady and sealing, solved preferably the problem of plunger type oil gas cylinder gas leak of the oil leakage.
In the present embodiment, cylindrical section is provided with at least one sealed muscle, is not limited to the twice described in the present embodiment.The sectional shape of sealed muscle is not limited to semicircle, also can be other arcuate shape, triangle or other shape.
