FIELD: mechanical engineering. SUBSTANCE: connection includes bolts placed along middle circle of flanges, washers, nuts and stopping plate in form of hollow concentric ring with figurate through apertures for nuts. Threaded connection of flanges is also equipped with second stopping plate, mounted on the side of bolt heads. Both stopping plates are pressed to flanges planes by magnetic forces. EFFECT: increased stopping reliability, simple construction, high manufacturability and low assembling\disassembling labor intensiveness for threaded flanges connection. 1 dwg
