Abstract

Cette vanne comprend une membrane montée par son bord entre le corps de la vanne et le chapeau, destinée à être appliquée en position d'étanchéité par un organe de pression sur la surface d'appui prévue dans le corps de la vanne, la membrane consistant en une couche mince de faible élasticité, par exemple en PTFE, faisant face à l'intérieur du corps et en une autre couche plus épaisse en caoutchouc élastique La couche en caoutchouc élastique 5 est pourvue sur son côté faisant face à l'organe de pression 6 de deux renflements 10 se soulevant en forme de coins en direction du rebord de la membrane 3 aménagés des deux côtés de sa partie médiane et orientés parallèlement à la surface d'appui 9. Cette vanne est utilisable sur toutes canalisations, notamment celles dans lesquelles circulent des liquides corrosifs.This valve comprises a membrane mounted by its edge between the valve body and the bonnet, intended to be applied in the sealing position by a pressure member on the bearing surface provided in the valve body, the membrane consisting in a thin layer of low elasticity, for example made of PTFE, facing the inside of the body and in another thicker layer of elastic rubber The elastic rubber layer 5 is provided on its side facing the pressure member 6 of two swellings 10 rising in the form of wedges in the direction of the rim of the membrane 3 arranged on both sides of its median part and oriented parallel to the bearing surface 9. This valve can be used on all pipes, in particular those in which circulate corrosive liquids.
