Abstract

Pour répondre aux exigences légales en termes de sécurité anti-chutes, les bouteilles de gaz sous pression pourvues de soupapes intégrées, dans lesquelles une pluralité de supports fonctionnels sont intégrés dans une unité de prélèvement, doivent être équipée de sécurités anti-chutes. Dans de telles soupapes, et pour de nombreuses variantes, telles que l'ajout d'une fonction supplémentaire, il faut effectuer à chaque fois une nouvelle procédure d'approbation pour l'ensemble de la soupape. Selon l'invention, pour réduire les coûts liés à cette procédure, il est prévu de monter un raccord de prélèvement de façon modulaire pour une bouteille de gaz sous pression. Un module de base, comportant l'élément d'obturation et un dispositif de sécurité anti-chutes protégeant l'élément d'obturation, satisfait à toutes les exigences légales en termes de sécurité anti-chutes et de dispositif d'obturation de la bouteille de pression. Toutes les autres fonctionnalités du raccord de prélèvement sont intégrées dans au moins un module additionnel qui est relié au module de base solidement mais de façon amovible et sans compromettre la sécurité anti-chutes.
