In order to realize the purpose of the utility model, the utility model adopts the technical scheme that:

a piston gas ring with high sealing performance comprises an annular body and is characterized in that the annular body is provided with a notch which is convenient for the annular body to expand and be assembled on a piston, an arc-shaped body is detachably arranged at the notch of the annular body, and the arc-shaped body and the annular body are combined to form a complete circular ring; set up annular first recess on the excircle face of the ring that the ring body and arc body are constituteed, set up annular second recess on the both sides wall of first recess, first recess is embedded to have the rubber circle, the rubber circles and is formed with the first bulge loop that can block into the second recess.

The utility model discloses a further improvement lies in, the both ends of arc body are equipped with curved inserted block, the both ends of ring body are formed with and supply inserted block male socket.

The utility model discloses a further improvement lies in, be stained with the rubber layer on the up end of the ring that the ring body and arc body are constituteed and the terminal surface down respectively, cushion the striking in the piston ring motion process.

The utility model discloses a further improvement lies in, annular third recess has been seted up on the up end of the ring that the ring body and arc body are constituteed and the lower terminal surface respectively, be formed with the second bulge loop that can block into in the third recess on the rubber layer, bond between second bulge loop and the third recess.

The utility model has the advantages that:

the utility model discloses through the cooperation of ring body and arc body, after the ring body assembles the ring channel of piston in, connect the arc body with the ring body through the inserted block, form complete ring, can prevent effectively that the opening from leaking gas, scurring oil phenomenon etc. from taking place; the utility model discloses a setting up of rubber ring can effectively improve whole sealing performance, has avoided high-pressure gas's leakage.
