Abstract
The utility model discloses a high-performance Y-shaped slip-ring sealing ring, comprising a Y-shaped sealing ring and an O-shaped ring embedded in the groove of the Y-shaped slip-ring with the Y-shaped slip-ring made from such materials as polytetrafluoroethylene, nylon and ultrahigh molecular weight polyethylene and the elastic ring made from rubber ring. The utility model is provided with the characteristics of simple structure, easy production, preferred sealing performance and high voltage resistance.
Description
Technical field
The utility model relates to a kind of high performance seal ring, is specially adapted to the reciprocating sealing of hydropneumatic, also is applicable to the low-speed rotation sealing.
Background technique
At present, the y-shaped ring of using in hydraulic pressure, pneumatic to-and-fro motion is mainly made by nitrile butadiene rubber or polyurethane, and is easy to wear because of its material and structural reason, and operating life is short, and frictional resistance is big, and heat resisting and pressure resisting is limited, easy oil leakage.And the sealing that can not apply to rotatablely move.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, good seal performance, and high pressure resistant, frictional resistance is little, long service life and the high-performance Y shape slip-ring sealed ring that can apply to rotatablely move.
The utility model is realized with following technological scheme: the sealing circle is made up of a Y shape slip ring and an O shape circle that embeds in the Y shape slip ring groove, form locking angle in Y shape slip ring lip back and slip ring, for ease of installing, leave lead angle at Y V-shaped ring heel, seal ring lip thickness is selected according to the operating mode needs.O shape circle is for having the rubber ring of pre compressed magnitude.
Good effect of the present utility model is: simple in structure, be easy to make high pressure resistant and good seal performance.
Description of drawings:
Below in conjunction with drawings and Examples 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.
Fig. 3 is the plan view that is used for piston seal.
Among the figure, (1) Y shape slip ring, (2) O shape circle, (3) piston, (4) cylinder body, (5) gland, (6) piston, (7) guide sleeve, direction shown in the arrow is the hydrodynamic pressure direction.α is that the angle of wedge, a are lip thickness.
Embodiment:
With reference to Fig. 1, the utility model is made up of Y shape slip ring (1) and O shape circle (2).O shape circle (2) embeds in the groove of Y shape slip ring (1), and O shape rubber ring has pre compressed magnitude, and Y shape slip ring lip thickness a is selected according to the operating mode needs.Locking angle is the 8-20 degree; The slip ring material adopts making such as teflon, nylon, ultra-high molecular weight polyethylene.
With reference to Fig. 2, Y shape slip-ring sealed ring is contained between piston rod (3) and the cylinder body (4), pushes down with gland (5).
With reference to Fig. 3, Y shape slip-ring sealed ring is contained between piston (6) and the guide sleeve (7), and cylinder body (4) is sealed.
Working principle is:
Direction shown in the arrow is hydraulic pressure or atmospheric pressure direction, Y shape slip ring lip limit part tightly is fitted in sealed surface, and in the corresponding increase of radial force of fluid pressure action lower seal, the applying on seal lip and sealed surface is tightr during work, so pressure is big more, sealability is good more.O shape is enclosed by the protection that slip ring contains of Y shape, thereby can " not extrude ", can tolerate high pressure.
Claims (4)
1, a kind of high-performance Y shape slip-ring sealed ring is characterized in that the O shape circle that seal ring is embedded by a Y shape slip ring and in the groove of Y shape slip ring forms, Y shape slip ring lip rear portion and lip formation locking angle, and heel has lead angle.
2, Y shape slip-ring sealed ring according to claim 1 is characterized in that Y shape slip ring teflon, nylon, superhigh molecular weight polyethylene material making.
3, Y shape slip-ring sealed ring according to claim 1 is characterized in that elastic ring is the rubber ring with pre compressed magnitude.
4, high-performance Y shape slip-ring sealed ring according to claim 1 is characterized in that locking angle is the 8-20 degree.
