Abstract

L'invention concerne un dispositif de prélèvement d'échantillons à partir d'un récipient, comprenant un appareil de prélèvement (6) présentant une tubulure (26) pouvant être raccordée avec une pièce de raccordement (4) du récipient (2). Dans cette tubulure est disposé un bouchon d'obturation (10) qui est relié avec un poussoir (24) pouvant être entraîné de manière à retirer ou à introduire le bouchon d'obturation (10) dans le récipient (2), dans le but de libérer ou d'obturer un passage vers une tubulure de sortie (34) pour l'échantillon à prélever. En vue de perfectionner le dispositif, le bouchon d'obturation (10) est disposé, de manière étanche au milieu, indépendamment de l'appareil de prélèvement, dans une tubulure de raccordement (8). La tubulure de raccordement (8) est montée sur une bride (18) qui est soudée au récipient (2). Le bouchon d'obturation (10) présente des moyens (22) pour le raccordement avec le poussoir (24), et la tubulure de raccordement (8) présente des moyens pour le raccordement avec la tubulure (26) dudit appareil de prélèvement (6).
