GATE FOR EXPLOSION-PROOF SHELLS OF NUCLEAR REACTOR Russian patent published in 2009 - IPC G21F7/05 F16K3/02 F16K31/524 

FIELD: physics, a nuclear physics.

SUBSTANCE: invention concerns field of nuclear power and is intended for hermetic overlapping of apertures in a protective shell at travel of the personnel and loads and can be used in emergencies on the atomic power station. The sluice contains installed in the case, at least, two doors with rotary shutters. Each shutter is supplied by the opening and closing mechanism, locking V-shaped device and a reducer. The locking V-shaped device is executed in the form of a cam. The cam is mounted on the arbor of a reducer and interacts with the V-shaped surfaces with rollers. Rollers are mobile disposed in the holder. Last is anchored in a frame pin. The frame interacts with a rotary shutter globe seats and is erected on rotary loops. Inferior from loops it is executed the drive. The mechanism of opening and shutter closing is executed in the form of system of levers, arbors and tractions. The system is related by one extremity to the distributive mechanism, and another - with a drive loop of a frame. Thanks to features of execution of the locking V-shaped device and the system of levers related to it, arbors and tractions of opening and closing of shutters the uniform hermetic sealing of a sluice irrespective of the geometrical shape of a door and an aperture is provided.

EFFECT: maintenance of hermetic overlapping of apertures in a protective shell at travel of the personnel and loads.
