Abstract
The utility model discloses a composite sealing ring. The utility model is characterized in that a groove-shaped packing ring (2) is inlaid on an O-shaped sealing ring (1), and the groove-shaped packing ring (2) is positioned in a plow groove of an object which needs to be sealed corresponding to the groove-shaped packing ring (2). Because the groove-shaped packing ring (2) and the O-shaped sealing ring are made of different materials, the utility model can reduce the friction drag which is caused when the sealed ring work, so the service life of the sealed ring can be prolonged. The groove-shaped packing ring is inlaid on the O-shaped sealed ring, and thus, the O-shaped sealing ring can not be squeezed out a sealing device when the O-shaped sealing ring is sealed in high pressure mode; accordingly, the normal work of the sealing ring can be ensured.
Description
The utility model belongs to field of sealing technology, particularly a kind of composite sealing 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 composite sealing 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 modelly be characterised in that embedding groove V-shaped ring on O-ring seals, the flute profile seal ring is placed in the groove of the need sealed object corresponding with it.
O-ring seals can adopt rubber material, and the flute profile seal ring can adopt wear resistant plastic material.
The utility model since flute profile seal ring and O-ring seals with different materials, so surface friction drag can reduce the startup work of seal ring time the, the working life of prolongation seal ring.The utility model can make O-ring seals not be extruded seal arrangement when bearing high pressure sealing owing to embedding on O-ring seals has added the flute profile seal ring, and is working properly to guarantee seal ring.
Below in conjunction with embodiment the utility model is described further.
Fig. 1 is the structural representation of this composite sealing ring.
Embedding adds flute profile seal ring 2 on O-ring seals 1, and the flute profile seal ring is placed in the groove of the need sealed object corresponding with it.When O-ring seals when bearing high pressure sealing, owing to inlayed flute profile seal ring 2 at it, make O-ring seals 1 not be extruded seal arrangement, flute profile seal band dynamic seal ring can with the groove of its corresponding object in slide, to guarantee normally carrying out of seal ring work.
O-ring seals 1 adopts rubber material, and flute profile seal ring 2 can adopt wear resistant plastic material, to reduce the starting friction resistance of seal ring.
Claims (2)
1. a composite sealing ring is characterized in that going up embedding groove V-shaped ring (2) at O-ring seals (1), and flute profile seal ring (2) is placed in the groove of the need sealed object corresponding with it.
2. composite sealing ring according to claim 1 is characterized in that O-ring seals (1) can adopt rubber material, and flute profile seal ring (2) can adopt wear resistant plastic material.
