Abstract

L'invention concerne un appareil de protection de remplissage d'azote pour reflux de saponification, comprenant un corps de tube (1). L'extrémité supérieure du corps de tube (1) est pourvue d'une section de connexion supérieure (2) destinée à être reliée à un tube de condenseur de reflux, et l'extrémité inférieure du corps de tube (1) est pourvu d'une section de connexion inférieure (3) destinée à être reliée à un flacon à fond rond ou à un flacon à fond plat. Un tube d'introduction de gaz (4) est disposé sur la paroi latérale du corps de tube (1). Le tube d'introduction de gaz (4) pénètre à travers la paroi latérale du corps de tube (1) depuis le côté extérieur du corps de tube (1) pour entrer dans une cavité interne du corps de tube (1). La section avant du tube d'introduction de gaz (4) située dans la cavité interne du corps de tube (1) est courbée vers le bas. Une transition d'arc est prévue au niveau de la position de courbure du tube d'introduction de gaz (4). L'axe de la section avant courbée du tube d'introduction de gaz (4) est parallèle à l'axe du corps de tube (1).
