Abstract
A sealing disc for vacuum closure suitable for using in reciprocating movement to an open position or a closed position to open or seal a valve port of an all-metal valve is disclosed. A sealing plate of the sealing disc is formed with a first sealing surface. When the sealing disc is in the closed position, the first sealing surface directly abuts against the valve port of the all-metal vacuum valve. A vacuum sealability can be improved and a service lifetime can be prolonged through compensating movement and adjusting movement between two metallic sealing surfaces abutting each other.
