CA 2340395

An isolation gate valve (10, 10a, 10b, 124, 146, 210) is provided which has a valve body (12, 126, 212) presenting a passageway (14, 214) therethrough; a shiftable, apertured gate member (18, 224) is located within the body (12, 126, 212) and is shiftable between a valve open position permitting flow through the passageway (14, 214) and a valve closed position wherein the member (18, 224) is shifted into a flow-blocking relationship relative to the passageway (14, 214). A valve actuator (20, 130, 220) is provided which includes a gas-generating cartridge unit (22, 22a, 22b, 222) which, upon actuation, generates a charge of high pressure subsonic gas for shifting the gate member (18, 224) at a velocity of about 0.2 to about 0.33 in./msec. Preferably, the actuator includes a piston housing (56, 56a, 56b, 256) having a piston (72, 72a, 72b, 272) therein with a piston rod (71, 71a, 71b, 271) coupled between the piston (72, 72a, 72b, 272) and the gate member (18, 224). In the valve open position, the piston (72, 72a, 72b, 272) is adjacent the cartridge unit (22, 22a, 22b, 222) and is oriented so that the pressurized gas from the cartridge unit (22, 22a, 22b, 222) shifts the piston (72, 72a, 72b, 272) thereby closing the valve (10, 10a, 10b, 124, 146, 212). A dampener unit (99, 299) is provided in an association with the gate member (18, 224) to effect predetermined, controlled deceleration thereof as the gate member approaches its fully actuated position.

L'invention concerne une vanne (10, 10a, 10b, 124, 146, 210) d'isolement à obturateur qui comporte un corps (12, 126, 121) de vanne présentant un passage (14, 214) traversant; un élément (18, 224) obturateur mobile à ouvertures situé dans le corps (12, 126, 212) peut être déplacé entre une position de vanne ouverte permettant un écoulement à travers le passage (14, 214), et une position de vanne fermée dans laquelle l'élément (18, 224) se met en position de blocage d'écoulement par rapport au passage (14, 214). Un actionneur (20, 130, 220) de vanne comporte une unité (22, 22a, 22b, 222) de cartouche génératrice de gaz qui, après actionnement, produit une charge de gaz subsonique haute pression qui déplace l'élément (18, 224) obturateur à une vitesse d'environ 0,2 à environ 0,33 pouces/ms. De préférence, l'actionneur comprend un logement (56, 56a, 56b, 256) de piston contenant un piston (72, 72a, 72b, 272) et une tige (71, 71a, 71b, 271) de piston couplée entre le piston (72, 72a, 72b, 272) et l'élément (18, 224) obturateur. Dans la position de vanne ouverte, le piston (72, 72a, 72b, 272) est adjacent à l'unité (22, 22a, 22b, 222) de cartouche et est orienté de sorte que le gaz pressurisé provenant de l'unité (22, 22a, 22b, 222) de cartouche déplace le piston (72, 72a, 72b, 272), ce qui permet de fermer la vanne (10, 10a, 10b, 124, 146, 212). Une unité (99, 299) d'amortisseur associée à l'élément (18, 224) obturateur sert à produire une décélération commandée prédéterminée de celui-ci au moment où l'élément obturateur approche de sa position d'actionnement complet.
