Description

Technical Field

[0001] This invention belongs to the field of mechanical manufacturing, and particularly relates to a storage tank sealing device, a capping device, a method for sealing storage tanks, and its application. Background Technology

[0002] Nowadays, in some mechanical manufacturing and processing processes, it is necessary to seal some materials before subsequent processing. For these materials, it is usually necessary to keep them under normal pressure and negative pressure inside the storage container. Existing storage component sealing devices use cylinders and other driving elements to push the sealing cover into place. Once in position, the sealing cover relies on its own weight (horizontal direction) and the thrust of the cylinder (vertical direction) to achieve a sealing effect. Because the sealing mechanism is too simple, it can only be used under normal pressure or when the negative pressure requirement is not high, but not under high positive or negative pressure requirements, and it is also more difficult to maintain later. Summary of the Invention
