Multi-port multi-stream valve apparatus

摘要

Apparatus for selecting connections from each of two or more inlet streams, at least two of which flow simultaneously, to one or more exit streams of a group of at least two. The apparatus has at least one rotatable first body, a first surface of which is adjacent to a first surface of a second body. The first body provides at least first and second fluid conduits, at least one end of each conduit terminating at the first surface of the first body. The second body also provides at least first and second fluid conduits, at least one end of each conduit terminating at the first surface of the second body. The first ends of each conduit provided by the first body and the first ends of each conduit provided by the second body are in such predetermined positions that the first conduit of the first body communicates with the second conduit of the second body. When such first body is rotated by a predetermined angle then the first conduit of the first body communicates with the second conduit of the second body and the second conduit of the first body communicates with the first conduit of the second body. The apparatus may be integrated into an end plate or end block of a reversing type electrodialysis or electrodeionization stack.
