Abstract
An apparatus for noise reduction in valves is disclosed. A disclosed example valve includes a valve body including a fluid passageway, and a cage located in the fluid passageway, the cage including a wall having openings, a fluid to flow from an inner surface of the wall to an outer surface of the wall through the openings, each of the openings including respective ribs, the ribs to follow a helical path along a length of each opening to cause rotation of the fluid flowing through the openings.
Claims20
A valve comprising:
- a valve body including a fluid passageway;
- and
- a cage located in the fluid passageway, the cage including a wall having openings, a fluid to flow from an inner surface of the wall to an outer surface of the wall through the openings, each of the openings including respective ribs, the ribs to follow a helical path along a length of each opening to cause rotation of the fluid flowing through the openings.
A cage to be located in a fluid passageway of a valve, the cage comprising:
- a wall having openings, a fluid to flow from an inner surface of the wall to an outer surface of the wall through the openings, each of the openings including respective elongated protrusions, the protrusions to follow a curved path along a length of each opening to cause rotation of the fluid flowing through the openings.
An apparatus comprising:
- means for providing a fluid passageway;
- and
- means for allowing a fluid to flow therein, the means for allowing the fluid to flow to include means for reducing noise through the fluid passageway, each of the means for reducing noise including respective means for generating rotation of the fluid.
