Abstract
A seal for vacuum flange connections includes a plastically deformable seal ing and an associated ring designed to ensure that the seal remains tight even upon cooling after a previous heating. This is obtained by providing a support ring having two resilient retaining portions, each for one plastically deformable seal ring. The design makes it possible to repeatedly use and re-use seal rings, which preferably are made of metal for example, gold.
Claims10
A seal for sealing a space between two flanges of a vacuum flange connection comprising, a support ring having two resiliently movable wall portions each associated with one flange and a plastically deformable seal ring disposed and deformable between each resiliently movable wall portion and an associated flange, whereby, when the space is sealed, the resiliently movable wall portions press said plastically deformable seal rings against their associated flanges and maintain the pressure even with variations in temperature.
A method of sealing a space between two flanges of a vacuum flange connection comprising, plastically deforming a plastically deformable seal ring against each flange and resiliently holding each plastically deformed plastically deformable seal ring against each flange using a support ring having two resiliently movable wall portions.
