Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Such as figure 2 shown.

[0019] A special high-strength and wear-resistant sealing ring for high-pressure self-sealing rotary compensators, the applicable pressure range is between 50MPa and 200MPa, and it is mainly composed of an annular support body 1 and a graphite sealing layer 2, and the graphite sealing layer 2 is passed through a high-pressure It is fixed on the two end faces of the annular support body 1 (the annular support body 1 and the graphite sealing layer 2 can be placed in the mould, and then the mold is molded on a 500-ton press), and the size of the annular support body 1 is determined by The size of the rotary compensator is determined, and its thickness generally does not exceed 50 mm, while the thickness of the graphite sealing layer 2 is generally between 0.5 and 5 mm. In order to improve the bonding strength between the ...

Abstract

The invention relates to a special high-strength wear-resistant sealing ring of a high pressure resistant self-sealing rotary compensator, comprising a circular supporting body (1) and graphite sealing layers (2) respectively fixed on both end surfaces of the circular supporting body (1). The invention has the advantages of simple structure, good pressure-resistant performance and wide range of application and is particularly suitable for sealing high-pressure movable surfaces.

Description

technical field [0001] The invention relates to a sealing ring, especially a high-pressure resistant sealing ring used in a compensator installed on a chemical pipeline and a steam power pipeline of a power plant, specifically a high-strength wear-resistant seal specially used for a high-pressure resistant self-sealing rotary compensator ring. Background technique [0002] At present, various types of rotary compensators are widely used in the pipelines used in the petrochemical industry and the power industry in order to meet the needs of thermal expansion and cold contraction, and high-pressure resistant sealing rings 5 ​​are installed in the rotary compensators, such as figure 1 As shown, the two end faces of the high-pressure resistant sealing ring 5 need to withstand high pressure when being squeezed and deformed, and are required to maintain sealing during relative movement. Ordinary sealing rings are easy to withstand high-pressure relative movement due to their inabi...
