摘要： To mount a partition cover (2) in a pipe joint (1), a nut (12) is screwed onto a joint body (11) to sandwich the partition cover (2) between the joint body and the nut. At this time, the partition cover is supported so as not to press a sleeve (13). As such, an opening (la) of the pipe joint is sealed while preventing the sleeve from being deformed due to the partition cover being mounted.

摘要： PROBLEM TO BE SOLVED: To provide a cover structure for a pipe joint for reliably sealing the opening of a pipe joint when mounting a partitioning cover on the pipe joint as a biting joint while suppressing the deformation of a sleeve, and to provide a partitioning cover to be used for the cover structure, a refrigerating device using the cover structure, and a pipe connecting method. SOLUTION: When mounted on the pipe joint 1, the partitioning cover 2 is held between a joint body 11 and a nut 12 by screwing the nut 12 into the joint body 11. At this time, the partitioning cover 2 is supported not to thrust the sleeve 13. Thus, the mounting of the partitioning cover 2 hermetically seals the opening 1a of the pipe joint 1 while preventing the deformation of the sleeve 13. COPYRIGHT: (C)2007,JPO&INPIT
