Title (EN) A HYDRANT VALVE
(FR) VANNE DE BORNE D'INCENDIE
Abstract:
(EN) A water hydrant valve (10) comprising a hollow body portion (12) with a water inlet (44) and a water outlet (46) and a sealing member (16) arranged to move between the water inlet (44) and the water outlet (46). The valve (10) is arranged so when water pressure is higher in the water main (60) than the feed pipe (58) the sealing member (16) seals against the water outlet (46) and requires an actuation means (70) to open the valve, and when water pressure is higher in the feed pipe (58) than the water main (60) the sealing member (16) seals against the water inlet (44) and thus prevents backflow into the water main (60).
(FR) La présente invention concerne une vanne de borne d'incendie (10) comprenant une partie de corps creux (12) avec une arrivée d'eau (44), une sortie d'eau (46) et un élément d'étanchéité (16) mobile entre l'arrivée (44) et la sortie d'eau (46). La vanne (10) est conçue de manière à ce que lorsque la pression d'eau est plus élevée dans le conduit principal (60) que dans le conduit d'alimentation (58) l'élément d'étanchéité (16) obture la sortie d'eau (46), l'ouverture de la vanne nécessitant alors un moyen d'actionnement (70), et lorsque la pression d'eau est plus élevée dans le conduit d'alimentation (58) que dans le conduit principal (60) l'élément d'étanchéité (16) obture l'arrivée d'eau (44) ce qui permet d'empêcher un retour dans le conduit principal (60).
