DEVICE FOR SEALING TRANSPORT OPENINGS OF THE TRANSPORT GATEWAY OF THE LOCALIZING SAFETY SYSTEM OF THE NUCLEAR POWER PLANTS (OPTIONS) AND METHOD OF SEALING THE TRANSPORT OPENINGS OF THE SHUTTERS SHOPPING CARE

摘要

1. A device for sealing transport openings of the transport lock of the localizing safety system of a nuclear power plant, containing flanges of the lock body along the edges of the transport openings with studs screwed into them and sealing sheets with sealing mechanisms installed on them, containing electric drives, shafts connected to electric drives with cavities at the ends and nuts located in the cavities of the shafts , made with the possibility of hermetic sealing of the mating points of the sealing sheets and flanges of the sluice body along the edges of the transport openings by means of mechanized screwing of nuts onto the studs and mechanized twisting of nuts from the studs, characterized in that the cavities in the shafts and the nuts are made of tetrahedral square sections, and the nuts are movably located in the cavities shafts with expansion gaps relative to the walls of the shaft cavities with the possibility of compensating for the misalignment of the mutual arrangement of nuts and studs and the non-perpendicularity of the studs relative to the plane sealing sheet 2. The sealing device according to claim 1, characterized in that the height of the faces of the cavities of the shafts is made greater than the length of the side faces of the nuts, but less than the diagonals of the section of the nuts. The sealing device according to claim 1, characterized in that the ends of the nuts on the side of the studs are made with a spherical surface and are equipped with movable washers with spherical recesses on the side of the nuts. The sealing device according to claim 1, characterized in that the ends of the nuts on the side of the electric drives are made spring-loaded by means of springs installed in the cavities of the shafts. The sealing device according to claim 1, characterized in that
