A fluid control valve (40) suitable for pressure reducing service. A valve is provided with a fixed cage member (76, 78, 80) containing an internal passageway (28) communicating with a cage inlet and outlet. A movable valve plug (60, 62, 64, 66) is slidably mounted within the cage member (76, 78, 80) and contains an internal plug passageway (32). A fluid flow path (20) is provided through the plug assembly (60, 62, 64, 66) and through the cage internal passageway (28) so that multi-stages of pressure reduction are obtained. The provided fluid flow (20) includes a combination of axial, outwardly radial, inwardly radial flows and a flow through the internal passageway (32) of the plug assembly in order to obtain the required multiple pressure drops. The restricted flow passages (26, 30, 34) at each stage are large enough in size so that any particulate in the fluid will pass out without plugging up the passages in the valve trim.

Cette invention concerne une soupape de régulation (40) du débit d'un fluide qui permet d'effectuer des réductions de pression. La soupape comporte un élément cage fixe (76, 78, 80) contenant un passage interne (28) se trouvant en communication avec une entrée et une sortie de cage. Un clapet (60, 62, 64, 66) de soupape mobile est monté coulissant dans l'élément cage (76, 78, 80), et comprend un passage interne de clapet (32). Une voie d'écoulement de fluide (20) traverse le dispositif de clapet (60, 62, 64, 66) et le passage interne (28) de la cage, de sorte que plusieurs étages de réduction de pression soient créés. L'écoulement de fluide (20) consiste en une combinaison d'écoulements axial, radial interne et radial externe, ainsi qu'en un écoulement traversant le passage interne (32) du dispositif de clapet, de sorte que les multiples chutes de pression voulues soient produites. Les passages à étranglement (26, 30, 34) de chaque étage possèdent une taille suffisante pour laisser passer toute matière particulaire dans le fluide sans que cela obstrue les passages dans les pièces internes de la soupape.
