DRAIN CONNECTOR FOR FLUID PROCESSING AND STORAGE CONTAINERS

摘要

A selectively closeable drain connector includes a hollow body or plunger moveable relative to a bore-defining drain flange. A locking element may be arranged to maintain the hollow body relative to the drain flange in one or more desired positions. At least one sealed jacket may extend between exterior portions of the drain flange and the hollow body to provide a barrier arranged to inhibit passage of contaminants to sealing surfaces along which the hollow body travels relative to the drain flange. The drain connector may be joined to a container, such as a tank, bag, vessel, or other receptacle for material storage and/or processing.
