Title (EN) SHUTTER OF PRESSURE VESSEL
(FR) OBTURATEUR DE CUVE SOUS PRESSION
Abstract:
(EN) A shutter of a pressure vessel developed to solve a problem of the space necessary for installing large pressure vessels of various types in a factory, since known apparatuses for covering a pressure vessel require a large space for transferring a lid body in opening the vessel. The shutter comprises a lid assembly (Y) constituted of a seal plate (1) formed of a flexible material of a size fit for the opening of a pressure vessel and a multitude of beam members (2) attached to the outer surface of the plate (1) and extending widthwise. The beam members are connected to the seal plate in such a manner as to be parallel to each other along a reference line for connection, extending in the widthwise direction of the seal plate, and advance or retract while flexing along a guide member (7) having at least one bending portion (71). The guide member is extended between a closing position A disposed in front of the opening portion and a housing portion B disposed on an outer housing of the pressure vessel, so that the assembly can be housed in a relatively small space. This shutter is most suitable for use on a medical autoclave and a retort for food processing.
(FR) Obturateur d'une cuve sous pression, mis au point pour résoudre un problème d'espace nécessaire à l'installation de grandes cuves sous pression de types divers dans une usine, puisque les appareils connus de couverture d'une cuve sous pression, nécessitent un grand espace afin de transférer un corps de couvercle pour ouvrir la cuve. L'obturateur comprend un ensemble (Y) de couvercle, constitué d'une plaque (1) d'étanchéité, composée d'une matière souple et d'une taille adaptée à l'ouverture d'une cuve sous pression, ainsi qu'une multitude d'éléments (2) de poutres, fixés à la surface extérieure de la plaque (1) et s'étendant dans le sens de la largeur. Les éléments de poutre sont raccordés à la plaque d'étanchéité, de manière à être parallèles les uns aux autres le long d'une ligne de référence pour permettre un raccordement, s'étendant dans le sens de la largeur de la plaque d'étanchéité, et avancent ou se rétractent tout en fléchissant le long d'un élément (7) de guidage doté d'au moins une partie (71) de flexion. L'élément de guidage s'étend entre une position A de fermeture, située devant la partie d'ouverture, et une partie B de logement disposée sur un logement extérieur de la cuve sous pression, de sorte que l'ensemble peut être logé dans un espace relativement réduit. Cet obturateur est le plus adapté à une utilisation sur un autoclave médical et sur une chambre de traitement d'aliments.
