More Information
Summary:A sealing disc (10) 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 (30) of the sealing disc (10) is formed with a first sealing surface (32). When the sealing disc (10) is in the closed position, the first sealing surface (32) 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.
