Abstract

L'invention concerne un clapet d'arrêt permettant de contrôler l'écoulement de gaz. Ce système comporte une conduite comprenant un première orifice de conduite, un deuxième orifice de conduite, et un troisième orifice de conduite, un piston primaire logé dans cette conduite pourvu d'un clapet de piston primaire configuré pour fermer avec étanchéité le troisième orifice de la conduite, et d'une première et d'une deuxième ouvertures. Ce système comprend un alésage s'étendant à partir de la première ouverture jusqu'à la deuxième ouverture. En outre, il est configuré pour faciliter la communication entre la première ouverture et le troisième orifice de conduite. Un élément d'étanchéité est monté entre la conduite et le piston primaire. Ce système est configuré pour empêcher le gaz de s'écouler dans la conduite entre le premier orifice de la conduite et le deuxième orifice de la conduite et entre les premier et troisième orifices de la conduite. Ce système comprend également un piston secondaire monté à l'intérieur de la conduite entre le piston primaire et le premier orifice de la conduite comprenant un premier clapet configuré pour fermer avec étanchéité la première ouverture du piston primaire et un deuxième clapet configuré pour fermer avec étanchéité le premier orifice de la conduite.
