Abstract

L'invention porte sur un dispositif de commutateur d'actionnement d'écoulement d'eau, lequel dispositif est installé sur un corps de tuyau (1). Le côté d'une section d'entrée d'eau (11) à l'avant d'un trou de limite (13) du corps de tuyau comporte un trou d'entrée d'eau (14). Le côté externe du trou d'entrée d'eau (14) est recouvert par une feuille de gel de silice (2). Un revêtement de fixation (3) recouvre étroitement la feuille de gel de silice (2). Une chambre supérieure (21) formée par le revêtement de fixation (3) et la feuille de gel de silice (2) et une section de sortie d'eau (12) du corps de tuyau communiquent entre elles par l'intermédiaire d'un canal de retour d'eau (15). Une chambre inférieure (22) formée par la feuille de gel de silice (2) et la paroi externe du corps de tuyau communiquent avec la section d'entrée d'eau (11) par l'intermédiaire du trou d'entrée d'eau (14). La surface de la feuille de gel de silice (2) comporte une structure de tige de poussée (4) qui est actionnée par la feuille de gel de silice (2) et connectée à un micro-commutateur d'écoulement d'eau (5), et un composant d'étanchéité à l'eau (32) est disposé entre la structure de tige de poussée (4) et le revêtement de fixation (3). La structure du dispositif de commutateur d'actionnement d'écoulement d'eau selon l'invention est simplifiée par rapport à l'état antérieur. De plus, la structure tire principalement parti de la récupération élastique de la feuille de gel de silice et de la pression de chambres d'étanchéité de l'ensemble de la structure pour générer une action sans être influencée par des impuretés dans l'écoulement d'eau, grâce à quoi la fiabilité est améliorée, et la possibilité de fuite d'eau est réduite.
