Title (EN) SELF CONTAINED GATE VALVE COLUMN LOADING PREVENTION MECHANISM
(FR) MÉCANISME D'EMPÊCHEMENT DE CHARGEMENT DE COLONNE DE SOUPAPE À TIROIR AUTONOME
Abstract: front page image
(EN)A valve assembly includes a valve body with a flow passage intersected by a valve cavity. A valve member is axially movable in the valve cavity between a closed position and an open position, the valve member having an opening that registers with the flow passage when the valve member is in the open position. A valve stem is threadingly connected to the valve member, the valve stem rotatable to move the valve member between the closed position and the open position. A collar assembly is located within a slot of the valve member and circumscribes the valve stem, the collar assembly having an annular collar shoulder. The valve stem has an annular load shoulder sized to engage the collar shoulder, limiting axial movement of the valve member.
(FR)L'invention concerne un ensemble soupape comprenant un corps de soupape doté d'un passage d'écoulement coupé par une cavité de soupape. Un élément de soupape est axialement mobile dans la cavité de soupape entre une position fermée et une position ouverte, l'élément de soupape ayant une ouverture coïncidant avec le passage d'écoulement lorsque l'élément de soupape est en position ouverte. Une tige de soupape est reliée par filetage à l'élément de soupape, la tige de soupape pouvant tourner pour déplacer l'élément de soupape entre la position fermée et la position ouverte. Un ensemble collier est situé à l'intérieur d'une fente de l'élément de soupape et circonscrit la tige de soupape, l'ensemble collier comportant un épaulement de collier annulaire. La tige de soupape comporte un épaulement de charge annulaire dimensionné pour entrer en prise avec l'épaulement de collier, limitant le mouvement axial de l'élément de soupape.
