Abstract

Agencement de vanne évitant les coups de bélier. La vanne comprend un logement 1 comportant un orifice d'entrée 2 et un orifice de sortie 3 dont la liaison peut être fermée par un piston différentiel 5 qui coulisse dans un cylindre 4 du logement 1, ce piston comportant un alésage 8 qui relie son grand côté 6 et son petit côté 7, la vanne comprenant en outre une conduite 15, 16, 17 allant de la chambre 10 du logement 1 jusqu'à l'orifice de sortie 3, la conduite 15, 16, 17 comportant un clapet pilote 14 de fermeture et d'ouverture. L'invention est caractérisée en ce que dans la conduite 16, 17 en aval du clapet pilote 14 se trouve un moyen de vanne 18 qui, à une pression prédéterminée s'exerçant sur son côté aval 17, ouvre son côté amont pour le soumettre à la pression de l'atmosphère environnante. La vanne selon la présente invention permet d'éviter les coups de bélier dans les conduites situées en avaL Application aux dispositifs d'irrigation en agriculture.
