Abstract
Cette vanne est du type composé d'un corps comportant deux tubulures et un logement transversal prolongeant un siège en forme, d'un obturateur mobile et des moyens de commande en translation de l'obturateur. Selon l'invention, cet obturateur est constitué par un noyau qui, ayant localement une forme généralement homothétique à celle du siège, est recouvert par une couche de matériau synthétique apte à assurer l'étanchéité par contact avec ce siège, et est lié, aux moyens de commande, avec un jeu longitudinal et avec interposition de moyens à ressort, tandis que les moyens de commande sont liés, de manière démontable, à l'obturateur. Cette vanne peut être utilisée sur toute conduite parcourue par des fluides divers, corrosifs ou non, notamment sur des wagons-citernes, et pour toutes applications cryogéniques.
