Abstract

L’invention concerne une prise de distribution de fluide (1), tel du gaz, comprenant un corps de prise (2) avec un passage central (3), des éléments de contrôle du passage de gaz (15, 16, 17) agencés de manière démontable et extractible, dans le passage central (3), et un système de sécurité (5, 6) agencé dans le passage central (3), entre l’extrémité amont (2a) de la prise (1) et les éléments de contrôle du passage de gaz (15, 16, 17). Le système de sécurité (5, 6) comprend une bille-clapet (5) et une chambre à bille (6) avec un orifice d’entrée de gaz (8) et un orifice de sortie de gaz (7), et un siège de clapet à bille (9) coopérant avec la bille-clapet (5). Selon l’invention, la paroi interne (10) de la chambre à bille (6) est conformée pour présenter une portion de forme générale conique ou tronconique (11) constituant le siège de clapet à bille (9) contre lequel vient appuyer la bille-clapet (5), et la conicité (α) de la portion de forme générale conique ou tronconique (11) et le diamètre de la bille-clapet (5) sont choisis de sorte que la bille-clapet (5) vienne coopérer de manière non-étanche avec le siège de clapet à bille (9), lorsque les éléments de contrôle du passage de gaz (15, 16, 17) sont extraits du passage central (3) et qu’une pression fluidique s’exerce sur la bille-clapet (5) en direction du siège de clapet à bille (9).
