Title
(EN) AIR SHUTOFF SWING GATE VALVE
(FR) CLAPET À OBTURATEUR OSCILLANT À ARRÊT D'AIR
Abstract
(EN) A swing gate valve is provided having a swing gate, a pivotable shaft having a swing arm disposed thereon such that rotation of the shaft causes rotation of the swing arm, a spring to urge the swing gate toward its closed position, a trigger assembly for securing the swing gate in its open position and for triggering the shaft to rotate including an actuator having a shaft and a receiver in the swing gate to receive the shaft, wherein when the shaft is in an extended position, the shaft is disposed in the receiver and the swing gate is locked in its open position, and wherein actuation of the actuator causes the shaft to withdraw to a retracted position out of the receiver, wherein the spring causes the pivotable shaft to rotate to move the swing gate to its closed position.
(FR) La présente invention se rapporte un clapet à obturateur oscillant possédant un obturateur oscillant, un arbre pivotant possédant un bras oscillant disposé sur celui-ci de sorte que la rotation de l'arbre entraîne la rotation du bras oscillant, un ressort pour pousser l'obturateur oscillant vers sa position fermer, un ensemble déclencheur destiné à immobiliser l'obturateur oscillant dans sa position ouverte et à déclencher la rotation de l'arbre comprenant un actionneur possédant un arbre et un récepteur dans l'obturateur oscillant pour recevoir l'arbre. Lorsque l'arbre se trouve dans une position étendue, l'arbre est disposé dans le récepteur et l'obturateur oscillant est bloqué dans sa position ouverte. L'actionnement de l'actionneur entraîne le retrait de l'arbre dans une position rétractée hors du récepteur, le ressort entraînant la rotation de l'arbre pivotant pour déplacer l'obturateur oscillant dans sa position fermée.
