Title (EN) HIGH PRESSURE ANTI-CAVITATION CAGE
(FR) CAGE ANTICAVITATION À HAUTE PRESSION
Abstract:
(EN) A control valve has a cage disposed within a valve body adjacent a valve seat and proximate a valve plug to provide guidance for the valve plug. The cage includes a solid, unitary circumferential wall with inlet passages adjacent one of an inner surface or an outer surface and outlet passages adjacent the other of the inner and outer surface. An annular cavity is spaced apart from the inner and outer surfaces and is connected to the inlet passages. Intermediate passages are connected to the annular cavity and recovery plenums interconnect the intermediate passages and the outlet passages. The recovery plenums have cross-sectional areas that are larger than a cross-sectional areas of the intermediate and outlet passages.
(FR) Selon la présente invention, une vanne de commande comporte une cage disposée à l’intérieur d’un corps de vanne adjacent à un siège de vanne et à proximité d’un bouchon de vanne pour fournir un guidage pour le bouchon de vanne. La cage comprend une paroi circonférentielle unitaire pleine avec des passages d’entrée adjacents à une surface interne ou à une surface externe et des passages de sortie adjacents à l’autre parmi les surfaces interne et externe. Une cavité annulaire est espacée des surfaces interne et externe et est raccordée aux passages d’entrée. Des passages intermédiaires sont raccordés à la cavité annulaire et des plénums de récupération relient les passages intermédiaires et les passages de sortie. Les plénums de récupération ont des aires de section transversale qui sont plus grandes que les aires de section transversale des passages intermédiaires et de sortie.
