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

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.

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...
