The fixture block is arranged opposite to the limiting ring.

And a through hole for the sealing ring main body to be inserted is formed in the sealing body.

The utility model has the advantages that:

1. the section of the sealing ring with good sealing performance in a high-pressure state is in a T-shaped design, and the clamping block can be pressed to tightly attach to the inner side of the flange under the high-pressure condition in the pipeline, so that the effect of enhancing the sealing performance is achieved;

2. the utility model relates to a sealing ring with good sealing performance under high pressure state is provided with a limiting ring, so that the sealing ring can not deform to the outside but vertically deform after being pressurized, thus the rubber ring is more attached to the flange connecting surface, and the sealing performance is further improved;

3. the utility model relates to a sealing washer that leakproofness is good under high pressure state is equipped with the beaded finish, has improved the intensity of sealing washer.
