It is fixed with transferring barrel cover lock when sealing cover and shielding bucket unlock, it can synchronize open two layers of sealing cover at this time, start to carry out material
Transfer operation.
Model festo DSNU-12-10-P-A linear motion double-acting cylinder can be selected in locking closure, unlock driving cylinder,
Supply gas pressure 6bar, theory action power 51N, stroke 10mm.The linear motion of this cylinder output has double action, driving shielding bucket
The rotation of cover locking ring realizes sealing cover and shields locking and the unlocking function of bucket；Drive lock pin flexible to realize chamber sealing cover
Determine with transferring barrel cover lock and unlocks.
It is provided with sealing ring between the shielding bung and airtight transhipment bung, when shielding bung and airtight transferring barrel cover lock
Periodically, shielding bung and the outer surface of airtight transhipment bung are bound tightly together by sealing ring, form double-canopy complex.
Its advantage is, airtight by sealing ring realization between bucket room sealing cover and transhipment bung, to prevent radioaerosol
The gap between two layers of lid is penetrated into, outer surface is caused to pollute.After " double-canopy " opens jointly, since the outer surface of two layers of lid is tight
It is thickly combined together, and is sealed by " bucket room sealing cover and transhipment bung sealing ring ", so, even if being exposed to radioactivity
In aerosol, outer surface will not be stain.After double-canopy complex separation, " inner surface " of complex becomes autonomous system
Outer surface will not be contaminated, and be in " clean " state.After " double-canopy " closure, all tables stain by radioaerosol
Face can will not all be exposed by system lock, prevented secondary volatilization and polluted.
As a further improvement, manual opening cover handle is additionally provided on institute's shielding bung, control shielding bung
Opening and closing.
As a further improvement, a barrel room sealing cover mandrel is fixedly installed in the middle part of the shielding bung.
A kind of double-canopy retaining mechanism of the utility model having the beneficial effect that compared with the existing technology
(1) it is suitable for storage transhipment volatility radioactive substance, transfer operation overall process keeps airtight conditions, prevents from putting
Penetrating property aerosol leaks to personnel's operating area, and the risk for causing radioaerosol to pollute significantly reduces；
