Title

(EN) LEAK ARRESTING MECHANICAL FLOW CONTROL VALVE
(FR) SOUPAPE DE REGULATION MECANIQUE D'ECOULEMENT ET ANTI-FUITE

Abstract:

(EN)A mechanical leak arresting valve (204) is disclosed in which fluid through the valve is limited to a range between a predetermined minimum flow rate and a predetermined maximum flow rate, and where both a small or large downstream leak mechanically causes the valve to lock closed. The present invention uses a locking mechanism triggered by a pressure differential resulting from the downstream leak to block the flow of fluid through the valve (224) until the fluid source upstream is stopped. Reduction of the upstream pressure by the stopping of the fluid source automatically resets the valve without further manipulation.
(FR)L'invention concerne une soupape de régulation mécanique anti-fuite (204), caractérisée en ce que le fluide s'écoulant à travers cette soupape possède un écoulement limité entre un débit minimal et un débit maximal, déterminés, et en ce qu'à la fois une fuite en aval, petite ou importante, provoque la fermeture mécanique de la soupape. L'invention met en oeuvre un mécanisme de blocage déclenché par un différentiel de pression résultant de la fuite en aval, aux fins de blocage de l'écoulement de fluide à travers la soupape (224), jusqu'à l'arrêt, en amont, de la source de fluide. La réduction de la pression amont, consécutive à l'arrêt de la source de fluide, remet automatiquement la soupape en position de marche, sans autre manipulation.
