Abstract
(EN)
A seal for a pressure chamber (10) is provided. The seal is formed by welding a loop of rigid tubular material (24) to the perimeter of the entry of a pressure chamber, conforming to the shape of the perimeter. A side wall of this tubing is machined off to produce a continuous slot (18) and a 'C'-shaped channel running along the perimeter of the entry. Tubular gasket material (16) is positioned in this 'C'-shaped channel to extend partially out of the slot to seal against the door (30) of the pressure chamber. A large diameter gasket may be used, and the interior of the gasket may be pressurized by a vent channel (36) connected with the interior of the pressure chamber.
(FR)
L'invention se rapporte à un joint étanche pour une chambre sous pression (10), qu'on obtient en soudant une boucle d'un matériau tubulaire rigide (24) au périmètre de l'entrée de la chambre sous pression, en lui faisant épouser la forme du périmètre. Une paroi latérale de ce tube est usinée jusqu'à présenter une fente continue (18) et un canal en forme de C, s'étendant le long du périmètre de l'entrée. Un matériau de garniture tubulaire (16) est disposé dans ce canal en forme de C, de façon à s'étendre partiellement hors de la fente et à former ainsi un joint étanche contre la porte (30) de la chambre sous pression. Une garniture d'étanchéité de grand diamètre peut être utilisée et l'intérieur de la garniture d'étanchéité peut être pressurisé au moyen d'un canal à évent (36) relié à l'intérieur de la chambre sous pression.
