Abstract

L'invention se rapporte aux équipements de lutte contre les incendies que l'on utilise dans le cadre de systèmes automatiques d'extinction d'incendies, et concerne notamment un arroseur pour envoyer un liquide d'extinction de feu, notamment de l'eau, sous forme d'un flux finement dispersé. Cet arroseur comprend un corps avec une ouverture de sortie fermée par un clapet à ressort de fermeture, un élément thermosensible frangible et un mécanisme d'actionnement de force. Le mécanisme d'actionnement de force est disposé sur le côté externe du corps servant à installer la surface de support inférieure de l'élément thermosensible frangible. Le mécanisme d'actionnement de force comprend un corps cylindrique creux dans lequel se trouve un piston capable d'interaction avec l'élément thermosensible frangible, d'un côté. De l'autre côté, le piston entre en interaction avec une rondelle sur laquelle est disposé l'élément chauffant. L'élément chauffant est disposé sur un côté de la rondelle. Sur l'autre côté de ladite rondelle se trouve une couche de brasure facilement fusible par laquelle ladite rondelle est soudée à une rondelle de support fixée dans le corps cylindrique creux. L'utilisation de cette solution technique permet une commande à distance fiable, un lancement forcé et un contrôle de l'état de l'arroseur du système d'extinction d'incendie.
