Abstract
A noise-attenuating module of a valve trim, including: a first divider plate; a second divider plate; and a plurality of flow segment plates disposed adjacent to and in contact with one another. At least one Herschel-Quincke tube flow path is formed by interconnected openings in the flow segment plates.A noise-attenuating cartridge to be placed transverse to the path of flowing fluid, the cartridge having: a plurality of flow segment plates disposed adjacent to and in contact with one another. At least one Herschel-Quincke tube is formed by interconnected openings in the flow segment plates.A noise-attenuating cartridge to be placed transverse to the path of flowing fluid, the cartridge including a segmented disk disposed with a first surface in an upstream side of the path of the flowing fluid and a second surface disposed in a downstream side of the path of flowing fluid. The segmented disk having at least two lateral mating faces with at least one Herschel-Quincke tube milled into at least one of the lateral faces, said Herschel-Quincke tube open at an inlet end to the first surface of the segmented disk and open at a discharge end at the second surface of the segmented disk.In …
