Abstract

La présente invention concerne une vanne d'un mélangeur pour agiter des matières médicales comprenant : un corps de vanne (1), un corps de bouchon (2), une tige de vanne (3) et un siège d'étanchéité (4). Le corps de bouchon (2) est pourvu symétriquement d'un trou traversant de médicament liquide (21), dont une extrémité est située à l'intérieur du corps de vanne (1) et l'autre extrémité est située à l'intérieur de la tige de vanne (3) traversant le siège d'étanchéité (4), et est raccordée à la tige de vanne (3) au moyen d'un boulon (6) ; le corps de bouchon (2), la tige de soupape (3) et le siège d'étanchéité (4) sont en plastique médical dur, le corps de bouchon (2) est emmanché sur un palier (8) sur un côté adjacent à la paroi inférieure d'un conduit, et l'extrémité inférieure du corps de vanne (1) est pourvue d'un tube de trop-plein (7) pour permettre au médicament liquide de s'écouler uniformément. La vanne du mélangeur permettant d'agiter des matières médicales présente une structure simple, une faible résistance de frottement lors de l'ouverture et de la fermeture du corps de vanne (1) et du corps de bouchon (2), un temps d'ouverture court et un joint étanche.
