Abstract
A device for controlling a liquid flow in a vertically extending pipe is disclosed which includes a plate member horizontally disposed in the pipe for receiving the liquid flow thereon and having an opening to permit the liquid received on the plate member to pass therethrough, a tubular guide downwardly inwardly extending from the periphery of the opening and terminating to form a liquid outlet, and a plurality of partition plates disposed on the tubular guide. Each partition plate has an upper end upwardly protruding from the periphery of the opening and a lower end obliquely downwardly extending from the periphery of the opening along the wall of the tubular guide member, so that a plurality of discrete passages are defined on the tubular guide. A cover plate is provided to cover the passages so that the liquid received on the plate member flows through the passages and is discharged from the liquid outlet of the tubular guide to form a vortex flow.
