Abstract

a. Vanne-papillon. b. Vanne-papillon dans laquelle un siège annulaire dur prévu dans le boîtier est destiné à entrer en contact avec un bord annulaire dur défini sur la périphérie de l'élément de vanne suivant toute la circonférence de ce dernier quand l'élément de soupape est perpendiculaire ou sensiblement perpendiculaire à l'axe du passage du fluide, vanne-papillon caractérisée en ce que le siège prevu dans l'enveloppe a une surface de contact qui coïncide avec la surface périphérique d'un cylindre imaginaire dont l'axe est incliné par rapport à l'axe du passage du fluide, dans la direction de la rotation de l'élément de vanne. c. L'invention s'applique notamment à la distribution des fluides.at. Butterfly valve. b. Butterfly valve in which a hard annular seat provided in the housing is intended to contact a hard annular edge defined on the periphery of the valve element along the entire circumference of the latter when the valve element is perpendicular or substantially perpendicular to the axis of the passage of the fluid, butterfly valve characterized in that the seat provided in the casing has a contact surface which coincides with the peripheral surface of an imaginary cylinder whose axis is inclined with respect to the axis of the fluid passage, in the direction of rotation of the valve element. vs. The invention applies in particular to the distribution of fluids.
