Abstract

L'invention concerne un dispositif de dérivation de fluide, qui utilise un dispositif de commande de canalisation d'embranchement pour réaliser la commande d'une canalisation d'embranchement. Une base (30) du dispositif de commande de canalisation d'embranchement comporte une ouverture à coulisseau (31) en communication étanche avec un corps de logement principal, un premier trou de montage (33) et un second trou de montage (32) qui sont en communication avec la canalisation d'embranchement. Un ensemble d'obturateur de vanne peut être entraîné par l'intermédiaire d'une partie d'entraînement (44) dans un ensemble chapeau (40) pour ouvrir et fermer l'ouverture à coulisseau. Dans une telle structure, il n'est pas nécessaire de traiter une face d'étanchéité parallèle et de niveau sur le corps de logement principal, ce qui se traduit par une procédure de traitement simple, et le dispositif de commande de canalisation d'embranchement n'a pas besoin de traiter le corps de logement principal (comprenant un tuyau principal et un réceptacle, etc.) dans une plate-forme en forme de colonne, ce qui réduit fortement les exigences en termes d'épaisseur d'une paroi de cavité et les difficultés de traitement, et réduit les coûts, et dans le même temps, le dispositif de commande de canalisation d'embranchement est directement intégré à une unité de commande de sorte que la marche/l'arrêt peuvent être commandés sans qu'il soit nécessaire d'installer une vanne supplémentaire.
