Appl. No.:

16/205408

Inventors:

International Classification:

F16K 47/08
F15D 1/02

Abstract:

A discharge for a fluid system has an inlet and an outlet in which a fluid flows from the discharge inlet to the discharge outlet. The discharge inlet has a inlet cross-sectional area. The discharge outlet has a plate. The plate has a plurality of radially extending ribs. The radially extending ribs are equiangularly spaced about a center axis of the plate. The radially extending ribs define a plurality of radially extending slots between the equiangularly spaced apart ribs. The radially extending ribs are dimensioned such that a sum of an area of all of the radially extending slots is greater than the discharge inlet cross-sectional area. When the fluid flows through the plate slots from the discharge outlet, it has a discharge coefficient of greater than 0.4.

Abstract:

A fixed cone sleeve valve has a conically shaped valve body and a sleeve gate movable relative to the valve body to define open and closed positions of the valve. An extension member is provided at the downstream distal end of the sleeve gate. The extension member extends radially outward and axially downstream from the distal end of the sleeve gate. The extension member has outer and inner surfaces with openings extending between the outer and inner surfaces. The extension member is arranged on the sleeve gate in a manner to allow communication through the openings into the flow path when the sleeve gate is in the open position.
