Abstract

L'invention concerne un dispositif de régulation de température à arrosage automatique qui comprend une vanne et un asperseur qui communique avec la vanne. La vanne comprend un couvercle de vanne, un corps de vanne et une tige de vanne à l'intérieur du corps de vanne. Un orifice de sortie d'eau qui communique avec une section d'écoulement, est utilisé dans le corps de vanne, et un piston ou une membrane qui ferme l'ouverture de sortie d'eau à température normale, est utilisé dans la partie inférieure de la tige de vanne. En outre, le dispositif de régulation de température comprend une tête de détection de température que l'on peut faire fonctionner et qui est reliée à la partie supérieure de la tige de vanne. La tige de vanne est commandée par la tête de détection de température de façon à ouvrir l'orifice de sortie d'eau lorsque la température ambiante monte jusqu'à une température prédéterminée, et pour fermer à nouveau l'ouverture d'entrée d'eau lorsque la température ambiante s'inverse pour revenir à la température normale. Le dispositif peut ouvrir ou fermer automatiquement la vanne en fonction de la modification de la température ambiante sans aucune énergie externe de telle sorte qu'on peut économiser de l'eau.
