Title
(EN) BALANCED-TORQUE BUTTERFLY VALVE
(FR) ROBINET PAPILLON A FORCE DE TORSION EQUILIBREE
Abstract
(EN)
A balanced-torque butterfly valve (40) incorporates a pivot mechanism (52) designed to provide for bimodal movement of the valve plate (42). The valve plate (42) has a cavity (54) formed therein to receive the pivot mechanism (52) and to accommodate translational movement of the valve plate relative to the mechanism. This eliminates fluid dynamic effects that would be produced if the mechanism were positioned in the flow path (44) and external to the valve plate (42). The pivot mechanism (52) comprises a center shaft (70) rotatable relative to the valve plate (42), and a carrier shaft (72) which is in fixed rotational relation to the valve plate (42) and extends through the mounting body (46). This permits both translational movement of the valve plate (42), and detection of its rotational position from a vantage point outside of the flow path (44). In addition, the carrier shaft (72) cooperates with bearings (104) to minimize load-bearing requirements of rack and pinion gears (64, 66, 116, 118) which are used to convert rotational movement of the center shaft (70) to translational movement of the valve plate (42).

Un robinet papillon à force de torsion équilibrée (40) incorpore un mécanisme de pivot (52) conçu pour permettre un mouvement bimodal de la plaque du robinet (42). Un creux (54), pratiqué dans ladite plaque de robinet (42) pour recevoir ledit mécanisme de pivot (52), le mouvement de translation de ladite plaque par rapport audit mécanisme. Des effets de fluide dynamiques, produits lorsque le mécanisme est positionné dans la voie d'écoulement (44) et externe à la plaque de robinet (42), sont ainsi évités. Le mécanisme de pivot (52) comprend une tige centrale (70) rotative par rapport à la plaque du robinet (42), ainsi qu'une tige de support (72) en relation de rotation fixe par rapport à la plaque du robinet (42) et s'étendant à travers le corps de montage (46). Le mouvement de translation de la plaque du robinet (42) ainsi que la détection, à partir d'une position avantageuse extérieure à la voie d'écoulement (44), de sa position de rotation sont ainsi assurés. De plus, la tige de support (72) coopère avec des paliers (104) de manière à réduire les besoins de charge des embrayages à crémaillière (64, 66, 116, 118) utiles pour la transformation du mouvement rotatif de la tige centrale (70) en un mouvement de translation de la plaque du robinet (42).
