Abstract

Certaines salles nécessitent pour le traitement de leur atmosphère des installations de ventilation ou de conditionnement d'air. Les fabrications ou les travaux réalisés dans ces salles peuvent nécessiter par moment l'interruption complète des arrivées et ou des extractions d'air. Ces installations doivent être équipées de registres étanches ne laissant passer que des débits de fuite faibles même en présence de différences de pression importantes entre l'amont et l'aval de ces registres. Le dispositif objet de l'invention est un registre à paires de volets antagonistes liés mécaniquement de manière à pivoter d'un même angle moyen et articulés et ayant la liberté de tourner légèrement par rapport à leurs bras de commande. Les dispositions relatives des éléments permettent d'obtenir des débits de fuite faibles même aux pressions les plus élevées utilisées en ventilation et conditionnement d'air. Ce registre trouve son application dans toutes les installations de ventilation ou conditionnement d'air où l'étanchéité est nécessaire et en particulier aux installations destinées à l'énergie nucléaire.
