Abstract
Valve trim apparatus for use with fluid valves are disclosed. An example apparatus includes a cage to be positioned in a fluid flow passageway of a valve body. The cage having a first end and a second end opposite the first end. The cage including columns extending between the first end and the second end at an angle relative to a primary fluid flow path of the cage. Each of the columns includes fluid flow passageways extending through the column from an outer peripheral surface of the column to an interior surface of the column. The columns are radially spaced about a circumference of the cage body to define fluid flow passageways between the columns.
Claims20
An apparatus comprising:
- a cage to be positioned in a fluid flow passageway of a valve body, the cage having a first end and a second end opposite the first end, the cage including columns extending between the first end and the second end, the columns including first ends positioned adjacent the first end of the cage at an angle relative to a primary fluid flow path of the cage, the primary fluid flow path of the cage extends in a first direction perpendicular to a longitudinal axis of the cage, wherein each of the columns includes fluid flow passageways extending through the column from an outer peripheral surface of the column to an interior surface of the column, and wherein the columns are radially spaced about a circumference of the cage body to define elongated openings only between the columns.
An apparatus comprising:
- a fluid valve body;
- and
- a cage disposed in the fluid valve body, the cage having a first end and a second end opposite the first end, elongated openings in the cage extending between the first end and the second end, the elongated openings radially spaced and non-parallel to a longitudinal axis of the cage, each of the elongated openings providing a fluid flow path between an interior of the cage and an exterior of the cage, the elongated openings having a first size adjacent the first end and a second size adjacent the second end, the first size different than the second size.
An apparatus comprising:
- means for defining a fluid flow passageway between an inlet and an outlet;
- means for modulating fluid flow between the inlet and the outlet, the means for modulating fluid flow angled relative to a primary fluid flow path of the means for defining the fluid flow passageway, the primary fluid flow path extends in a first direction perpendicular to a longitudinal axis of the means for defining a fluid flow passageway, the means for modulating fluid flow including an interior surface, an outer peripheral surface opposite the interior surface, a first side surface between the interior surface and the outer peripheral surface, and a second side surface opposite the first side surface, the means for modulating fluid flow including apertures extending through the first side surface to the second side surface.
