Technical solution is used by the utility model solves its technical problem：A kind of PTFE and PU combined seal rings, packet
Sealing ring main body is included, the upper and lower ends of the sealing ring body side are equipped with external seal lip face and interior sealing lip face, in institute
It states and O-ring is equipped between external seal lip face and interior sealing lip face, circular arc complementary area is equipped in the sealing ring bottom part body,
The circular arc complementary area, which embeds, is cased with PTFE seal component, and PTFE components opening gear is additionally provided in the sealing ring body surfaces
Circle.
As a kind of preferred technical solution of the utility model, when piston rod is used together, around described close
The outside in seal main body and external seal lip face is equipped with piston component, and in the sealing ring main body and interior sealing lip face
Bottom is connected with piston rod packing face.
As a kind of preferred technical solution of the utility model, shape between the external seal lip face and interior sealing lip face
Into arc groove, the O-ring is placed in arc groove.
As a kind of preferred technical solution of the utility model, the circular arc complementary area is wavy shaped configuration, and described
Wave crest there are two being set on the both ends of circular arc complementary area.
Compared with prior art, the beneficial effects of the utility model are：The utility model increases O-ring compensating sealing surface
The effect of compression strength guide support is increased with PTFE component split washers, which is suitble to super-pressure, the fast work of the speed of service
Condition.
