Abstract

a. Soupape d'obturation à clapet, notamment pour canalisation à fluide sous pression; b.Soupape caractérisée en ce que les lèvres d'étanchéité dont les bords libres situés à l'intérieur présentent, en position d'ouverture par rapport au clapet un faible diamètre de passage et sont disposées de manière à céder élastiquement par rapport au déplacement de fermeture du clapet; c. L'invention s'applique aux soupapes d'obturation à clapet, notamment pour canalisation à fluide sous pression.at. Shutter valve, in particular for pressurized fluid pipelines; b.Valve characterized in that the sealing lips whose free edges located inside have, in the open position relative to the valve, a small passage diameter and are arranged so as to yield elastically with respect to the displacement of closing of the valve; vs. The invention applies to shut-off valves, in particular for pressurized fluid pipelines.
