<P>PROBLEM TO BE SOLVED: To provide a pipe connection structure which prevents anybody from easily loosening a screw connection part by separating a grip part of a connection member after completion of pipe connection and preventing generation of noise by the separated grip part, a valve using the pipe connection structure, a pipe joint, and a refrigeration device. <P>SOLUTION: This pipe connection structure is provided with a joint body 1, and the connection member 2 externally installed on piping P to be connected and fastened to the joint body 1. The fastening member 2 includes a pipe connection part 23 screwed to the joint body 1, and the grip part 24 formed in such a manner that the same can be gripped with a general fastening tool. Both of the parts are integrated in such a manner that the same are separated by rotation torque after completion of fastening of the joint body 1 and the connection member 2. The separated grip part 24 is fixed under a condition where the same is externally installed on the piping P not to rotate nor move in a pipe axial direction. <P>COPYRIGHT: (C)2009,JPO&INPIT |
