Title
(EN) CLOSURE VALVE FOR WASTE GAS CHAMBER
(FR) CLAPET D'OBTURATION D'UNE ENCEINTE DE GAZ DE COMBUSTION
Abstract
(EN)
The invention concerns a safety valve (2) for a chamber (4) comprising a frame (10), a shutter (30), control means for actuating (48, 60) the shutter to open and to close an orifice (18) of the chamber, and further releasing means (46) for automatically closing the shutter when the pressure level in the chamber reaches a predetermined threshold. The shutter (30) is mounted sliding relatively to the frame (10).
(FR)
Le clapet (2) de sécurité pour une enceinte (4) comprend un châssis (10), un obturateur (30), des moyens commandés d'actionnement (48, 60) de l'obturateur pour l'ouverture et la fermeture d'un orifice (18) de l'enceinte et, en outre, des moyens de libération (46) pour l'ouverture automatique de l'obturateur lorsqu'une pression dans l'enceinte atteint un seuil prédéterminé. L'obturateur (30) est monté coulissant par rapport au châssis (10).
