Abstract

The utility model discloses a U-shaped slip ring sealing piece which consists of a U-shaped ring and an O-shaped elastic ring embedded in a U-shaped slip ring groove. The utility model has the characteristics of simple structure, easy production, high pressure enduring and extremely good sealing performance.

Description

The U-shaped slip-ring sealed ring
The utility model relates to a kind of high performance seal ring, is specially adapted to the reciprocating sealing of hydropneumatic.
At present, mainly form by U-shaped rubber ring, supporting ring at the U-shaped seal ring that hydraulic pressure, pneumatic to-and-fro motion are used, its complex structure, rubber seal is easy to wear, and is not high pressure resistant, easily upset, frictional force is bigger than normal, and working life is short.
The purpose of this utility model provides a kind of simple in structure, and good seal performance is high pressure resistant, and frictional force is little, the high-performance U-shaped slip-ring sealed ring of long service life.
The utility model is realized with following technological scheme: the sealing circle is made up of the O shape elastic ring in a U-shaped slip ring and the embedding U-shaped slip ring groove, leaves lead angle at U-shaped slip ring heel, and bearing ring seal lip thickness is selected according to the operating mode needs.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is a plan view of the present utility model.
Fig. 2 is the installation plan view that is used for rod seal.
Among the figure, (1) U-shaped slip ring, (2) O shape circle, (3) piston rod, (4) cylinder body, (5) gland, 6 is the lip limit thickness of U-shaped slip ring, arrow is depicted as the direction of hydrodynamic pressure.
With reference to Fig. 1, O shape elastic ring (2) embeds in the groove of U-shaped slip ring (1), and O shape elastic ring uses rubber ring usually, and O shape circle has pre compressed magnitude, and U-shaped slip ring lip thickness δ is selected according to the operating mode needs.In the present embodiment, the U-shaped slip ring adopts polytetrafluoroethylmaterial material to make.
With reference to Fig. 2, the U-shaped slip-ring sealed ring is contained between piston rod (3) and cylinder body (4), and is tight with gland (5) lid.Direction shown in the arrow is hydraulic pressure or atmospheric pressure direction.U-shaped slip ring lip limit part tightly is fitted in sealed surface.In the corresponding increase of effect lower seal radial force of hydrodynamic pressure, seal ring lip and sealed 's applying is tightr during work, so pressure is big more, sealability is good more.
Owing to adopted such scheme, the utility model to be compared with existing technology to have simple in structure, be easy to make Advantage, and good seal performance, frictional force is little, and is high pressure resistant, the life-span is long. Be applicable to all kinds of plant equipment moving, Static seal is particularly useful for the sealing of hydraulic pressure, Pneumatic reciprocating, but both hole usefulness, but also axle is used.

Claims (3)

1, a kind of U-shaped slip-ring sealed ring is characterized in that seal ring is made up of a U-shaped slip ring (1) and the O shape elastic ring (2) that embeds in the U-shaped slip ring groove, leaves lead angle at U-shaped slip ring heel.
2,, it is characterized in that the U-shaped slip ring makes of polytetrafluoroethylmaterial material according to the described U-shaped slip-ring sealed ring of claim 1.
