<p><P>PROBLEM TO BE SOLVED: To provide a flange connection device capable of easily and surely connecting a partner flange and including a lock mechanism preventing a clamp plate itself from being rotated from a connection position during transportation of a fluid wherein the parter flange is connected the flange connection device. <P>SOLUTION: The partner flange 71 is connected to a flange-like connection plate body 2 with a plurality of clamp plates 15. The clamp plate rotated by a compression coil spring 20 following the rotation of a fastening bolt 10 in a fastening direction is configured in such a manner that engagement recessed/protruded parts 26, 27 formed in the clamp plate and a receiving part 22 are fitted at a pressing rotating position where rotation is locked by a rotation regulating stopper 25 so that the clamp plate is regulated in an unrotatable locked state at the pressing rotating position. A connection guide member 40 with a guide part 41 guiding and supporting the partner flange at the connection position is attached radially movably, and the guide part is made to function as the rotation regulating stopper 25. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
