CA 2507160

A vapor-liquid contact tray is provided with a quick opening manway. The manway includes an opening formed in the tray and overlying cover formed by a pair of panels joined together by a center hinged connection. The cover panels of the manway have upturned flanges formed along the lateral margins of the cover. The flanges are removably received within inverted U-shaped brackets that are positioned along the lateral margins of the tray adjacent the manway opening. When the cover is closed, the flanges are received tightly within the associated brackets to secure the lateral margins of the cover to the tray. The cover can be opened by lifting one or both cover panels to cause them to fold together about the center hinge. As the cover panels are lifted, the flanges tilt within the brackets and are released from engagement therewith. The end margins of the cover panels are secured to the adjacent portions of the tray by conventional manway clamps.

L'invention concerne une plaque de contact vapeur-liquide pourvue d'un passage pour homme à ouverture rapide. Ledit passage présente une ouverture, ménagée dans la plaque, et un couvercle formé par une paire de panneaux reliés par une charnière centrale. Les panneaux de recouvrement du passage présentent des rebords relevés formés le long de bordures latérales du couvercle. Lesdits rebords sont reçus de manière amovible dans des supports en forme de U renversé qui sont positionnés le long des bordures latérales de la plaque, adjacentes à l'ouverture du passage. Lorsque le couvercle est fermé, les rebords sont reçus de manière serrée dans des supports associés de sorte que les bordures latérales du couvercle soient fixées à la plaque. Pour ouvrir le couvercle, on soulève un panneau ou les deux panneaux pour les replier autour de l'articulation centrale. Lorsque les panneaux de couvercle sont relevés, les rebords basculent dans les supports et sont désengagés de ces derniers. Les bordures d'extrémité des panneaux de couvercle sont fixées à des parties adjacentes de la plaque par des éléments de serrage classiques.
