Abstract

La présente invention concerne une soupape servant à empêcher les retours de fluide dans une conduite Cette soupape comprend un siège de soupape 1 et un élément de fermeture 2. Ce dernier est enfoncé avec une certaine tension sur le siège 1 et recouvre les orifices 10 par lesquels le fluide doit s'écouler. Le siège de soupape 1 et l'élément de fermeture 2 comprennent des brides 3 et 4 permettant de connecter la soupape entre deux portions de tubes 5 et 6. Le siège de soupape comprend une pluralité de petits orifices de passage 10 dont la dimension principale est inférieure à l'épaisseur de paroi du siège 1 et sensiblement égale à l'écartement entre deux orifices 10. L'invention permet l'utilisation d'éléments de fermeture de très faible épaisseur dans les soupapes.
