Abstract

En raison du niveau de pollution d'un réfrigérant liquide s'écoulant au travers des tubes d'échangeurs de chaleur d'unités de conditionnement d'air et de condenseurs, il est essentiel de nettoyer les tubes à intervalles réguliers au moyen de dispositifs de nettoyage mécaniques tels que des brosses. La soupape requise pour inverser l'écoulement normal doit être de dimensions réduites, robuste, et de conception simple. A cet effet, on propose une soupape (1) dans laquelle deux extrémités de tube (3-4) (5-6) sont chacune d'elles disposées dans leur plan respectif, et dans laquelle le canillon (9) est supporté de manière mobile. Le canillon possède à cet effet deux passages d'écoulement (15-16) dans le sens normal d'écoulement, lesquels relient les extrémités de tube par le chemin le plus court. Pour le sens inverse d'écoulement, le canillon est pourvu de deux passages en forme de spirale (17-18) qui relient de manière indépendante et croisée les extrémités des tubes.
