Problems solved by technology

As the pressure increases, the contact force between the sealing element and the top cover and the end of the cylinder will also decrease to a certain extent. At this time, a sealing effect with a large pre-tightening force is required to complete it, so its applicable range caused certain restrictions

Abstract

The invention relates to a sealing structure and method applied to a high-pressure container. The structure comprises the high-pressure container, an unloading opening is formed in the high-pressure container, a step is arranged at one end of the high-pressure container and used for containing an anti-explosion piece for detecting the sealing effect, mineral powder with certain gradation is arranged on the anti-explosion piece, and a gap is formed between the anti-explosion piece and the inner wall of the high-pressure container; water is injected into the high-pressure container through a water injection mechanism, the mineral powder with certain gradation flows towards the threaded gap between the anti-explosion piece and the inner wall of the high-pressure container under the pushing effect of water, the threaded gap is filled in order, and sealing is achieved. The sealing method of the technical scheme is more efficient than a traditional sealing mode or based on a high-pressure container structure type or by utilizing a special sealing material. According to the sealing structure and method, mineral powder is used for plugging, the method is a reliable supplement of a conventional sealing mode, and the mineral powder is a product generated through rapid unloading of the high-pressure container but not specially customized. Therefore, the sealing method is simple, efficientand reliable.

Description

technical field [0001] The present application relates to a sealing structure and method applied to high-pressure containers. Background technique [0002] At present, the sealing of high-pressure vessels can be roughly divided into the following categories: (1) forced sealing (2) self-tightening seal (3) semi-self-tightening seal. [0003] Forced sealing, this sealing method mainly uses the tension force of the bolts to achieve the sealing between the top cover, the sealing element and the cylinder end. As the pressure increases during the operation, the bolts will be deformed, the top cover will rise, etc., so that the contact pressure will be greatly reduced, so it is necessary to have a sufficiently strong bolt pre-tightening force to ensure the sealing effect. If the actual operating pressure is relatively large or the diameter of the container is large, the mandatory sealing effect will be greatly reduced. [0004] Self-tightening seals, including O-ring seals, C-rin...
