Abstract

The invention relates to a double cover sealing structure, and belongs to the technical field of sealing device. When a shielding barrel and a shielding barrel cover are tightly locked, an airtight transferring barrel cover and a shielding barrel cover are in an unlocking state, a gas discharging valve of the shielding barrel cover and a ventilation valve of an airtight transferring barrel cover are automatically started, at the moment shielding isolating device inner cavities are formed by the shielding barrel cover and the airtight transferring barrel cover to allow an airtight transferringbarrel to be communicated with an inner cavity of a shielding barrel, it is ensured that the air pressure in the airtight transferring barrel and the air pressure in the shielding barrel are the same,and therefore the opening and closing of the airtight transferring barrel cover can be smoothly completed; after the airtight transferring barrel cover and the shielding barrel cover are tightly locked, the gas discharging valve of the shielding barrel cover and the ventilation valve of the airtight transferring barrel cover are automatically switched off, and therefore it is ensured that the shielding barrel and the airtight transferring barrel maintain respectively airtight states.
