Abstract

La présente invention concerne un robinet-vanne et, plus particulièrement, un robinet-vanne conçu de telle sorte que, lorsqu'un élément d'ouverture/fermeture a ouvert/fermé, un passage de fluide, le déplacement de l'élément d'ouverture/fermeture entraîne la juxtaposition sélective d'un élément d'étanchéité au bord périphérique extérieur de l'élément d'ouverture/fermeture ou du passage de fluide, ce qui permet d'améliorer l'étanchéité à l'air, et la structure simple facilite l'assemblage et la réparation. Le robinet-vanne selon la présente invention comprend : un ensemble corps comportant un premier passage de fluide formé sur un premier côté de celui-ci et un espace d'ouverture/fermeture formé dans celui-ci de manière à être perpendiculaire au premier passage de fluide et à être ouvert sur l'autre côté de celui-ci ; un couvercle ayant un deuxième passage de fluide formé dans celui-ci de manière à être accouplé à l'autre côté de l'ensemble corps, ce qui permet de fermer l'espace d'ouverture/fermeture ; un élément d'ouverture/fermeture qui coulisse à l'intérieur de l'espace d'ouverture/fermeture au moyen d'un actionneur, ce qui permet d'ouvrir/fermer l'espace entre le premier passage de fluide et le deuxième passage de fluide ; un élément d'étanchéité, qui présente un troisième passage de fluide formé dans celui-ci, et qui est monté entre l'élément d'ouverture/fermeture et le couvercle ; et un élément de mise sous pression monté entre l'élément d'étanchéité et le couvercle, ce qui permet de mettre sous pression l'élément d'étanchéité vers l'élément d'ouverture/fermeture, dans lequel une saillie de contrainte est formée sur une des surfaces en vis-à-vis de l'élément d'ouverture/fermeture et de l'élément d'étanchéité ; une rainure de contrainte est formée sur l'autre des surfaces en vis-à-vis de l'élément d'ouverture/fermeture et de l'élément d'étanchéité, la saillie de contrainte étant sélectivement introduite dans la rainure de contrainte ; la saillie de contrainte n'est pas introduite dans la rainure de contrainte, lorsque l'élément d'ouverture/fermeture se déplace, de telle sorte que l'élément d'étanchéité se déplace tout en étant espacé de l'élément d'ouverture/fermeture par la hauteur de la saillie de contrainte ; et la saillie de contrainte est introduite dans la rainure de contrainte, lorsque l'élément d'ouverture/fermeture ne se déplace pas, de telle sorte que l'élément d'étanchéité est poussé contre la surface intérieure d'un premier côté de l'élément d'ouverture/fermeture ou de l'ensemble corps par l'élément de mise sous pression.
