A pressure vessel sealing and locking structure

Abstract

The invention relates to a sealing and locking structure of a pressure vessel. The sealing and locking structure comprises a first annular groove formed in the barrel end of the pressure vessel in the circumferential direction and a second annular groove formed in a top cover of the pressure vessel in the circumferential direction. After the top cover is mounted at the barrel end, a groove opening of the first annular groove and a groove opening of the second annular groove are opposite to each other, and then an annular channel with the cross section being round is formed. The annular channel is filled with shearing-resistant steel balls making the barrel end and the top cover be locked. By means of the sealing and locking structure of the pressure vessel, traditional sealing and locking structures are changed, and the shearing-resistant steel balls are adopted for locking; the weight of both the barrel end and the top cover is greatly reduced, the manufacturing cost of the vessel is reduced, the operation safety is good, and the economical benefits are remarkable; and the problem that shearing-resistant parts of the traditional sealing and locking structures of pressure vessels are prone to being stuck in use is solved, the opening difficulty is greatly lowered, the operation cost is substantially reduced, and the economical efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of pressure vessel design and manufacture, and in particular relates to a pressure vessel sealing and locking structure. Background technique [0002] In the design of pressure vessels, the recommended sealing structures for pressure vessels with design pressure not higher than 35MPa include metal flat gasket seal, double cone ring seal, Wood seal, Kazari seal, and clamp quick-open seal. In the design of high-pressure vessels, it is recommended that the quick-opening sealing structure be a boltless connection type, including clamp connection, shear bolt connection, shear pin connection and shear ring connection. [0003] In recent years, the development of pressure vessels has been moving towards high parameterization. The sealing structure with shear connection is easy to be seized under the action of pressure, and it is not easy to disassemble, and the operation efficiency is low. The thickness of the mat...
