Title (EN) BALL VALVE WITH MODAL SILENCER
(FR) CLAPET À BILLE AVEC SILENCIEUX MODAL
Abstract:
(EN) A ball valve includes a control element including a perforated screen (90) disposed within the control element and spaced apart from an inner surface of the control element to form an annular space (76) and a plurality of chambers (74) disposed within the control element. When fluid flows through the control element, sound waves pass through the perforated screen and are reflected back by the plurality of chambers to disrupt other sound waves, thereby reducing fluid noise in the rotary valve.
(FR) L'invention a trait à un clapet à bille comprenant un élément de commande comprenant un tamis perforé (90) disposé à l'intérieur de l'élément de commande et espacé d'une surface interne de l'élément de commande pour former un espace annulaire (76) et une pluralité de chambres (74) disposées à l'intérieur de l'élément de commande. Lorsqu'un fluide s'écoule à travers l'élément de commande, des ondes sonores traversent le tamis perforé et sont réfléchies par la pluralité de chambres de façon à perturber d'autres ondes sonores, réduisant ainsi le bruit du fluide dans le clapet à bille.
