Title
(EN) VALVE TRIM APPARATUS FOR USE WITH CONTROL VALVES
(FR) APPAREIL D'ÉQUIPEMENT INTERNE DE VANNE DESTINÉ À ÊTRE UTILISÉ AVEC DES VANNES DE COMMANDE
Abstract
(EN)
Valve trim apparatus for use with fluid valves are disclosed. An example apparatus includes a cage (200) to be positioned in a fluid flow passageway of a valve body. The cage having a first end (202) and a second end (204) opposite the first end. The cage including columns (206) 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 (210) extending through the column from an outer peripheral surface (212) of the column to an interior surface (214) of the column. The columns are radially spaced about a circumference of the cage body to define fluid flow passageways (220) between the columns.

La présente invention concerne un appareil d'équipement interne de vanne destiné à être utilisé avec des vannes à fluide. Un exemple d'appareil d'équipement interne de vanne comprend une cage destinée à être positionnée dans un passage d'écoulement de fluide d'un corps de vanne. La cage a une première extrémité (202) et une seconde extrémité (204) opposée à la première extrémité. La cage comprend des colonnes (206) s'étendant entre la première extrémité et la seconde extrémité à un angle par rapport à un trajet d'écoulement de fluide primaire de la cage. Chacune des colonnes comprend des passages d'écoulement de fluide (210) s'étendant à travers la colonne depuis une surface périphérique externe (212) de la colonne jusqu'à une surface intérieure (214) de la colonne. Les colonnes sont radialement espacées autour d'une circonférence du corps de cage pour définir des passages d'écoulement de fluide (220) entre les colonnes.
