The invention relates to all sides pressing sealed type high pressure resistance sealing ring with framework belonging to a sealing material. The invention is characterized in that: the sealing ring is formed by a long strip framework (1) with the height H no less than 10mm and a long strip flexible sealing material (2) which are superposed and wrapped. Two end surfaces, the outer circular surface and the inner circular surface of the wrapped annular ring are respectively provided with coating layers (3), and the compressive strength is between 200MPa and 480MPa. The sealing ring has the advantages of simple structure, excellent compressive performance and wide application range, which is especially applicable to the sealing of a high pressure active surface.
