Abstract

L'invention concerne une vanne hydraulique du type à ouverture manuelle et à fermeture automatique. La vanne est caractérisée en ce qu'elle comporte un corps en une seule pièce, ayant une partie centrale creuse ainsi qu'une partie d'entrée et une partie de sortie sous la forme de brides munies d'un orifice pour le fluide et de trous pour le passage de moyens de fixation à des conduites, la partie centrale étant munie de moyens d'obturation pour boucher au moins partiellement l'orifice de la partie de sortie, de moyens de commande pour commander la mise en position d'ouverture ou fermeture des moyens d'obturation et boucher également, en position de fermeture, un orifice de débit lent afin qu'aucun liquide ne puisse traverser la vanne, et de moyens de reglage pour le débit de l'orifice de débit lent et la vitesse de fermeture de la vanne Une telle vanne permet d'assurer ou d'interrompre le transfert de liquides dits << dangereux >> entre deux conduites.
