Title (EN) VALVE WITH CONTOURED BORE TO DEFLECT PARTICLES
(FR) SOUPAPE DOTÉE D'UN ALÉSAGE PROFILÉ SERVANT À DÉVIER DES PARTICULES
Abstract:
(EN) A valve (10, 158) having a flow control assembly (28, 164) with a bore (54, 118, 162, 172, 174, 178) having particle-deflecting features (120, 122, 124, 126, 174, 176, 178, 180) is provided. In one embodiment, the bore of a flow control assembly of a valve includes a contour shaped to deflect particles in a fluid stream through the valve toward the center of the fluid stream and away from a sealing surface (94, 170) of the flow control assembly. The bore may also, in some embodiments, create a Venturi effect that cleans sealing surfaces by drawing particles away from the sealing surfaces. Additional valve systems, devices, and methods are also disclosed.
(FR) L'invention concerne une soupape (10, 158) présentant un ensemble de commande d'écoulement (28, 164) pourvu d'un alésage (54, 118, 162, 172, 174, 178) ayant des éléments de déviation de particules (120, 122, 124, 126, 174, 176, 178, 180) . Dans un mode de réalisation, l'alésage d'un ensemble de commande d'écoulement d'une soupape comprend un contour façonné de façon à dévier des particules dans un flux de fluide à travers la soupape vers le centre de l'écoulement de fluide et à l'écart d'une surface d'étanchéité (94, 170) de l'ensemble de commande d'écoulement. L'alésage peut également, dans certains modes de réalisation, créer un effet Venturi qui nettoie les surfaces d'étanchéité par aspiration des particules hors des surfaces d'étanchéité. L'invention concerne également des systèmes de soupapes supplémentaires, des dispositifs et des procédés.
