Title (EN) FLUID FLOW CONTROL DEVICE HAVING A PARTICLE CATCHER
(FR) DISPOSITIF DE COMMANDE D'ÉCOULEMENT DE FLUIDE À PIÈGE À PARTICULES
Abstract:
(EN) A fluid flow control device (100) includes a valve body (102) defining an inlet (104), an outlet (106), and a fluid flow path (108) extending therebetween, a valve seat ring (116) coupled to the body that defines an orifice through which the fluid flow path passes, a cage (120) coupled to the body that defines an interior bore (122), a control element (130) slidably disposed within the interior bore of the cage, and a particle catcher (140) at least partially disposed within an interior bore of the control element. The particle catcher includes a particle catcher body (142) that defines an inner flow path (144) and at least one particle catcher passage (148) through which the fluid flow path passes. An outer surface (142c) of the particle catcher and an inner surface of the control element form a particle catching portion (150). The at least one particle catcher passage directs the fluid flow path downwardly into the particle catching portion.
(FR) Un dispositif de commande d'écoulement de fluide (100) comprend : un corps de vanne (102) définissant une entrée (104), une sortie (106) et un trajet d'écoulement de fluide (108) s'étendant entre celles-ci ; une bague de siège de vanne (116) qui est couplée au corps et qui définit un orifice à travers lequel passe le trajet d'écoulement de fluide ; une cage (120) qui est couplée au corps et qui définit un alésage intérieur (122) ; un élément de commande (130) disposé de manière coulissante dans l'alésage intérieur de la cage ; et un piège à particules (140) disposé au moins en partie dans un alésage intérieur de l'élément de commande. Le piège à particules comprend un corps de piège à particules (142) qui définit un trajet d'écoulement interne (144) et au moins un passage de piège à particules (148) à travers lequel passe le trajet d'écoulement de fluide. Une surface externe (142c) du piège à particules et une surface interne de l'élément de commande forment une partie de capture de particules (150). Ledit au moins un passage de piège à particules dirige le trajet d'écoulement de fluide vers le bas jusque dans la partie de capture de particules.
