Title
(EN) ROTARY VALVE
(FR) ROBINET
Abstract
(EN)
A rotary valve provides a casing having an inlet (26) and an outlet (28) and a shaft mounted plug (34) that selectively covers the inlet. A seat ring (48) having an inner seating shoulder (52) that is eccentric relative to the body bore of the inlet is provided. The seat ring can be rotated to accommodate variations in the center of the plug for more accurate seating. The plug can be provided with a secondary plug that selectively covers the outlet and that moves relative to the outlet in response to movement of the shaft (38). The outlet can include a low noise structure having, in one embodiment, a set of tapered slots that vary the flow cross section along the flow path.
(FR)
La présente invention concerne un robinet dont le corps est pourvu d'une entrée (26) et d'une sortie (28) et dont le boisseau (34) est monté sur pivot de façon à vient aveugler sélectivement l'entrée. Le siège (48) comporte un épaulement intérieur (52) de positionnement qui est excentré par rapport à l'alésage de l'entrée du corps. Le siège peut tourner épousant ainsi les décentrages de boisseau, ce qui permet d'assurer un appui plus précis sur siège. Le boisseau peut être accompagné d'un boisseau secondaire venant aveugler sélectivement la sortie et se déplaçant par rapport à la sortie en réaction à un mouvement de l'axe (38). Selon une réalisation, la sortie peut comporter une structure de silencieux constituée d'un ensemble d'orifices coniques permettant de faire varier la section d'écoulement le long du circuit d'écoulement.
