Abstract

Le bourrelet conformateur 31 faisant saillie sur la cloison 14 de la coquille 1 pour l'appui de la membrane 3 entre les tubulures 6, 7 présente, dans un plan perpendiculaire au dessin, un profil longitudinal incurvé dont la concavité est opposée à celle de la cavité de commande 10 de l'autre coquille 2 et la surface intérieure de cette cavité est conformée de façon dissymétrique, la profondeur de la partie 32b située en regard de la tubulure de sortie 7 étant plus grande que la partie 32a située en regard de la tubulure d'entrée 6. La vanne peut être utilisée dans tout circuit véhiculant un fluide sous pression; elle est applicable notamment au contrôle du remplissage des cuves à hydrocarbures, produits chimiques ou autres.
