Title: Sealing method for vacuum vessel
Inventor: FUJII YOSHIKI
IPC: F16J12/00
Filed: 1990-04-17
Abstract: PURPOSE:To surely seal the inside of a vacuum vessel easily and inexpensively by simultaneously performing pressure reduction between inner and outer seal members with the inner seal member being spaced from a flange or cover, and exhausting inside the vacuum vessel. CONSTITUTION:After inner and outer seal members 15, 16 are arranged on a flange 12, a cover 13 is mounted with a bolt 17 and a nut 18. With a gap between the member 15 and the cover 13 being left, only the member 16 is fastened by the bolt to seal a vacuum vessel. Next, the inside of vacuum vessel main body 1 is pre-exhausted, air between the members 16, 15 is discharged through the gap. Then when the pressure decreases to a specified level, the bolt 17 is fastened further to bring the member 15 into close contact with the flange 12 and the cover 13. As a result, the space decreased in pressure is formed between the members 15, 16. Exhaust operation in the vacuum vessel is substantially carried out.
