FERRULE JOINT, AND SEALING MECHANISM FOR LIQUID PASSAGE NOZZLE IN MEMBRANE MODULE

摘要

To provide a ferrule coupling which is easy to mount onto members to be coupled such as pipe conduits and apparatuses and can reliably maintain the sealability even when subjected to temperature rises and falls due to a sterilization process etc. A ferrule coupling 1 has an annular male screw member 10 which is provided on one of members to be coupled and has a thread formed on the outer peripheral surface, and an annular female screw member 11 which is provided on the other of the members to be coupled and has a thread formed on the inner peripheral surface. The male screw member 10 and the female screw member 11 are screw-engaged with each other to thereby couple the members to be coupled with each other. The male screw member 10 has a cut section 23 at one part in the circumferential direction, and can be opened or closed such that the cut section 23 widens or narrows.
