TRANSPORT LOCKER OF SAFETY SYSTEM OF NUCLEAR POWER PLANT Russian patent published in 2019 - IPC G21F7/05 

FIELD: machine building.

SUBSTANCE: invention relates to atomic engineering. Transporting gateway of localizing safety system of nuclear power plant includes cylindrical housing, in flanges of which there are made transport openings. Each of openings is equipped with elliptical cover with locking mechanisms of cover clamping. Locking mechanism is made in the form of a bayonet lock, and consists of an elliptical cover, ledges interacting with grooves made along the inner diameter of the bayonet rotary ring. Bayonet ring is installed on housing flange. Each bayonet ring is equipped with centering devices installed along its circumference, interacting with housing flange by means of rollers located on axis of centering device. Each rotation mechanism comprises a drive. Cooling channels are made in flanges of cover and housing. To open gateway opening covers are equipped with diametrically installed rollers resting on brackets of recoil frame. Clamping mechanisms are fixed on the cover for compression of seal of bayonet lock. Each clamping mechanism comprises a drive connecting the lid and the sliding frame to move the lid along the housing axis.

EFFECT: invention makes it possible to provide air-tightness of gate apertures.
