Abstract
The utility model discloses a combined sealing ring. The utility model is characterized in that a C-shaped ring (2) is inlaid on the outer surface of an O-shaped sealing ring (1), the outer diameter of the O-shaped sealing ring (1) is slightly larger than the inner diameter of the C-shaped ring (2). Because the C-shaped ring and the O-shaped sealing ring (1) are made of different materials, the utility model can reduce the frictional resistance of the sealing ring when the sealing ring is started and used, and the utility model can prolong the service life of the sealing ring. Because a C-shaped ring is additionally inlaid outside the O-shaped sealing ring (1), and thus, the O-shaped sealing ring can not be extruded out a sealing device when the O-shaped sealing ring is sealed in a high pressure mode so as to ensure normal work of the O-shaped sealing ring.
Description
The utility model belongs to field of sealing technology, particularly a kind of combined seal ring that is made of different materials.
Normally used O-ring seals, when work started, surface friction drag was big, and working life is short.When O-ring seals is subjected to high pressure, usually be extruded seal arrangement, make its cisco unity malfunction.
The purpose of this utility model makes provides a kind of combined seal ring, and it has when work starts surface friction drag little, long service life, characteristics working properly when bearing high pressure sealing.
For reaching above-mentioned purpose, of the present utility model being characterised in that on the outer surface of O-ring seals (1) inlays that " [" shape ring (2), the external diameter of O-ring seals (1) are slightly larger than " internal diameter of [" shape ring (2).
" [" shape ring can adopt wear resistant plastic material.
The utility model is because " [" shape ring and O-ring seals be with different materials, so the surface friction drag can reduce the startup work of seal ring the time, the working life of prolongation seal ring." [" shape ring can make O-ring seals not be extruded seal arrangement when bearing high pressure sealing, and is working properly to guarantee it owing to added in the embedding of the outside of O-ring seals.
Below in conjunction with embodiment the utility model is described further.
Fig. 1 is the structural representation of this combined seal ring.
Outer surface embedding at O-ring seals 1 adds " [" shape ring 2.When O-ring seals when bearing high pressure sealing " [" shape ring 2 makes O-ring seals 1 not be extruded seal arrangement, to guarantee normally carrying out of its work owing to be with in its outside.
O-ring seals 1 adopts rubber material, and " [" shape ring 2 can adopt wear resistant plastic material, to reduce the starting friction resistance of seal ring.
The external diameter of O-ring seals 1 is slightly larger than that " internal diameter of [" shape ring makes it reach good sealing effect.
Claims (2)
1. combined seal ring is characterized in that inlaying that " [" shape ring (2), the external diameter of O-ring seals (1) are slightly larger than " internal diameter of [" shape ring (2) on the outer surface of O-ring seals (1).
2. combined seal ring according to claim 1 is characterized in that " [" shape ring (2) can adopt wear resistant plastic material.
