Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] A four-sided pressure-sealed high-pressure-resistant sealing ring with a skeleton, which is formed by laminating and winding a long skeleton 1 with a width of not less than 10mm and a long flexible sealing material 2, and on both ends of the wound annular ring And the outer and inner circular surfaces are provided with cladding layer 3, its compressive strength is between 200MPa ~ 480MPa, such as figure 1 shown. During specific implementation, the skeleton 1 can be one or a combination of flat plates, corrugated plates, toothed plates or arc-shaped plates, wherein figure 1 The corrugated plate shape shown has the best compressive strength, and the skeleton 1 of the corresponding shape can be selected according to the maximum pressure surface borne by the sealing ring in the actual implementation. When the main direction of force is the end face,...

Abstract

A four-sided pressure-sealed high-pressure resistant sealing ring with a skeleton, which belongs to a sealing material, is characterized in that it is laminated by a long skeleton (1) with a height H of not less than 10mm and a long flexible sealing material (2) It is wound, and a coating layer (3) is provided on the two ends, the outer circular surface and the inner circular surface of the wound annular ring, and its compressive strength is between 200MPa and 480MPa. The invention has the advantages of simple structure, good pressure resistance and wide application range, and is especially suitable for sealing high-pressure movable surfaces.

Description

technical field [0001] The invention relates to a sealing ring, in particular to a high-pressure-resistant annular sealing ring, in particular to a four-sided pressure-sealed high-pressure-resistant sealing ring with a skeleton. Background technique [0002] At present, high-pressure resistant sealing rings are often used in pipelines used in the petrochemical industry and power industry, and such sealing rings are required to withstand pressure in four directions and maintain it for a long time, and sometimes even require relative movement between the sealing surfaces. Because the sealing ring cannot withstand the relative movement under high pressure, it is easy to disintegrate and embrittle under high pressure, and cannot achieve the sealing effect. The maximum pressure resistance of various sealing rings in the existing manuals generally does not exceed 50MPa. When the pressure exceeds this Professional design of the sealing structure must be carried out, which greatly i...
