Claims

[Scope of utility model registration request]

An exhaust valve and a pressure difference gauge are provided at the exhaust section to seal inert gas into the casing of the centrifuge, and a warning whistle for detecting the gas is provided at the inert gas intake section. The abutment area between the opening edge of the opening and the opening/closing lid that opens and closes the opening has a sealing structure with double gaskets installed concentrically, and an inert gas is filled in the space between the two gaskets. , an explosion-proof device for a centrifuge, further comprising: opening/closing the exhaust valve and opening/closing the automatic inert gas intake valve in conjunction with a signal from a detector that detects opening/closing of the opening/closing lid; .
