Title (EN) HYDROSTATIC DRAIN PLUG
(FR) BOUCHON D'EVACUATION HYDROSTATIQUE
Abstract:
(EN) A hydrostatic drain plug/outlet assembly comprises a hollow body (1) with an inlet port and an outlet port for connection to a fluid conduit. A slidable valve member (6) is movable between a locked open position and a locked closed position via an intermediate position at which the valve member (6) is urged into sealing engagement with a sealing member (3) by a spring (21) which supports a hydrostatic pressure of predetermined magnitude beyond which excess hydrostatic pressure is relieved by the valve member to prevent liquid overflow in a vessel. The valve member is moved between the locked open position and the locked closed position by rotation of valve member (6).
(FR) 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).
