Abstract

Un ensemble de sortie/bouchon d'évacuation hydrostatique est composé d'un corps creux (1) et d'une ouverture d'arrivée et une ouverture de sortie devant être reliés à un tuyau pour fluide. Un élément de vanne coulissant (6) peut être déplacé entre une position ouverte verrouillée et une position fermée verrouillée en passant par une position intermédiaire dans laquelle l'élément de vanne (6) est sollicité en engagement étanche avec un élément d'étanchéité (3) par l'intermédiaire d'un ressort (21) qui supporte une pression hydrostatique d'une intensité prédéterminée au-delà de laquelle la pression hydrostatique en excès est réduite par l'élément de vanne afin d'empêcher le débordement de liquide dans un récipient. L'élément (6) est déplacé entre la position ouverte verrouillée et la position fermée verrouillée par la rotation de l'élément (6).
