Abstract

L'invention concerne un élément de valve automatique destiné à réguler l'écoulement d'un tuyau. L'élément de valve automatique de la présente invention détecte une fuite de fluide ou un écoulement de fluide anormal. L'élément de valve automatique comprend un espace, est ouvert au niveau d'une première extrémité et présente au niveau d'une seconde extrémité un élément d'arrêt d'écoulement de fluide, c'est-à-dire une vanne d'arrêt. L'élément de valve automatique comprend un dispositif de détection de pression différentielle activant la vanne d'arrêt et présentant une expansion ou une contraction en fonction de la pression extérieure. Le dispositif de détection de pression différentielle communique avec une sortie de l'élément de valve. Ainsi, lorsque la pression de la sortie de l'élément de valve est inférieure à celle d'une entrée, le dispositif de détection de pression différentielle se contracte, ce qui entraîne l'ouverture de la vanne d'arrêt. La présente invention permet, par conséquent, de déterminer une occurrence de fuite de fluide en fonction de la fréquence à laquelle une quantité de fluide supérieure au volume du dispositif de détection de pression passe à travers la valve.
