FERRULE COUPLING AND SEALING MECHANISM FOR LIQUID PASSAGE NOZZLE OF MEMBRANE MODULE

摘要

A ferrule coupling 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 has an annular male screw member 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 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 and the female screw member are screw-engaged with each other to thereby couple the members to be coupled with each other. The male screw member has a cut section at one part in the circumferential direction, and can be opened or closed such that the cut section widens or narrows.

主权项

1. A ferrule coupling used in the field of manufacturing of pharmaceutical and medical products or food manufacturing, the ferrule coupling comprising:
an annular male screw member which can be fitted on one of members to be coupled and has a thread formed on the outer peripheral surface; and an annular female screw member which can be fitted on the other of the members to be coupled and has a thread formed on the inner peripheral surface, wherein the male screw member and the female screw member are screw-engaged with each other to thereby couple the members to be coupled with each other, and the male screw member has a cut section at only one part in the circumferential direction, and can be opened or closed such that the cut section widens or narrows.
