Abstract

La présente invention concerne un dispositif pour empêcher la déformation d'un siège à ressort pour une tête d'extincteur installée sur un plafond de façon à diffuser un liquide d'extinction d'incendie dans quatre directions lorsqu'un incendie survient, de telle sorte qu'il est possible d'empêcher, fondamentalement, une fuite d'eau provoquée par la déformation du siège à ressort en raison d'une fixation excessive lors du procédé d'assemblage de la tête d'extincteur. A cet effet, la présente invention est caractérisée en ce que, en liaison avec l'assemblage d'un siège à ressort (3) dans une rainure concave (2c) formée sur une partie d'orifice (2b) d'un corps (2) et la mise sous pression du siège à ressort (3) par la partie d'orifice (2b) de telle sorte que la charge d'assemblage du siège à ressort (3) est ajustée, la hauteur (H) de la partie d'orifice du corps (2) est réglée pour être plus grande que la hauteur (h) depuis la surface supérieure d'un déflecteur (20), la rainure concave (2c) formée sur la partie d'orifice (2b) présente une profondeur (d) à laquelle la charge effective maximale du siège à ressort (3) présente une valeur maximale lorsque la tête (100) est assemblée de telle sorte que la surface inférieure d'une plaque de charge interne (9) vient en butée contre la surface inférieure du déflecteur (20) et un rebord saillant vers le haut (9a) est formé sur la surface supérieure de la plaque de charge interne (9) de manière à présenter une taille inférieure au diamètre interne d'une ouverture de décharge d'eau (2a) de telle sorte que le rebord saillant vers le haut (9a) est relié à la surface inférieure du déflecteur (20).
