Static sealing structure suitable for high-pressure medium

The invention provides a static sealing structure suitable for a high-pressure medium. The static sealing structure suitable for the high-pressure medium comprises a butt flange A and a butt flange B,wherein the butt flange A is provided with an axially extending guide section; the guide section is annular and can be inserted into a channel of the butt flange B; an annular groove is formed in theouter surface of the guide section of the butt joint flange A; a first O-shaped rubber sealing ring is arranged in the annular groove in a sleeved mode; a radial through hole is formed in the side surface of a flange plate of the butt flange B; an annular liquid containing groove is formed in the outer surface, corresponding to the tail end of the radial through hole, of the guide section of thebutt flange A; a medium-pressure medium is introduced into the static sealing structure through the radial through hole; the annular liquid containing groove is filled with the medium-pressure mediumthrough the radial through h
