Title (EN) FIXED CONE SLEEVE VALVE WITH FINGER EXTENSIONS ON SLEEVE GATE FOR CAVITATION SUPPRESSION AND MULTI-JET DISCHARGE MEMBER
(FR) CLAPET À BOISSEAU CONIQUE FIXE DOTÉ D'EXTENSIONS DE DOIGT SUR UNE GRILLE DE BOISSEAU POUR SUPPRESSION DE CAVITATION ET ÉLÉMENT DE DÉCHARGE À JETS MULTIPLES
Abstract:
(EN) A fixed cone sleeve valve has a conically shaped valve body and a sleeve gate movable relative to the valve body to define open and closed positions of the valve. An extension member is provided at the downstream distal end of the sleeve gate. The extension member extends radially outward and axially downstream from the distal end of the sleeve gate. The extension member has outer and inner surfaces with openings extending between the outer and inner surfaces. The extension member is arranged on the sleeve gate in a manner to allow communication through the openings into the flow path when the sleeve gate is in the open position.
(FR) L'invention concerne un clapet à boisseau conique fixe, comportant un corps de clapet de forme conique et une grille de boisseau mobile par rapport au corps de clapet pour définir des positions ouverte et fermée du clapet. Un élément d'extension est prévu au niveau de l'extrémité distale aval de la grille de boisseau. L'élément d'extension s'étend radialement vers l'extérieur et axialement en aval de l'extrémité distale de la grille de boisseau. L'élément d'extension comporte des surfaces externe et interne avec des ouvertures s'étendant entre les surfaces externe et interne. L'élément d'extension est disposé sur la grille de boisseau de manière à permettre une communication à travers les ouvertures dans le trajet d'écoulement lorsque la grille de boisseau est en position ouverte.
