摘要

PROBLEM TO BE SOLVED: To provide a flareless type pipe connection structure temporarily retaining a ferrule manufactured as a separate member at the end of the joint body of a connection member not to be damaged from the outside and simplifying temporary retaining work, and a valve, a pipe joint, and a refrigeration unit, each using the flareless type pipe connection structure.;SOLUTION: The flareless type pipe joint includes a joint body 1, a connection member 2 screwed in the joint body 1, the ferrule 3, and a partition lid 4. The ferrule 3 is formed separately from the joint body 1 and the connection member 2, and has a rear end temporarily retained at the end of the joint body of the connection member 2. The partition lid 4 is removably mounted at the end of the joint body of the connection member 2 while storing the ferrule 3 into an internal space when the connection member 2 is not fastened to the joint body 1. In mounting work, the ferrule 3 is push-pressed in an axial direction to be temporarily retained to the connection member 2 by the partition lid 4.;COPYRIGHT: (C)2010,JPO&INPIT
