Title (EN) ADJUSTABLE BREAKAWAY VALVE COUPLING
(FR) RACCORD DE VANNE, REGLABLE ET A DEGAGEMENT RAPIDE
Abstract:
(EN) A breakaway valve coupling comprises first (4) and second (8) couplings including respective first and second bodies (12). First and second valve members (72) are movable between an open position, when the first and second coupling assemblies (4, 8) are mated to each other position and a closed position. The first and second bodies (12) include a plurality of lugs (52) adapted to interdigitally engage each other, each lug (52) including a slot (60) circumferentially aligned to each other. A spring clip (152) is seated in the slots (60) to hold said lugs together. A ring plate (160) is selectively positioned relative to a spring (172) such that the compression on the spring (172) may be adjusted, thereby changing the amount of force applied by a collar (156) on the spring clip (152) and hence the amount of force required to separate apart the first and second coupling assemblies (4, 8).
(FR) Un raccord frangible pour vanne comprend des premier (4) et deuxième (8) raccord comportant des premier et deuxième corps (12) respectifs. Les premier et deuxième éléments (72) de vanne sont mobiles entre une position ouverte, dans laquelle les premier et deuxième ensembles (4, 8) de raccord sont appareillés ensemble et une position fermée. Les premier et deuxième corps (12) comprennent une pluralité de pattes (52) prévues pour s'intercaler mutuellement, chaque patte (52) comprenant une fente (60) alignée de manière circonférentielle sur l'autre. Une bague (152) de serrage est logée dans les fentes (60) pour maintenir ensemble lesdites pattes. Une plaque (160) annulaire est placée sélectivement par rapport à un ressort (172) de telle sorte que la compression s'exerçant sur le ressort (172) puisse être réglée, ceci permettant de varier la quantité de force appliquée par un collier (156) sur la bague (152) de serrage et par conséquent la quantité de force nécessaire pour séparer les premier et deuxième ensembles (4, 8) de raccordement.
