Abstract

L'invention concerne un dispositif de raccord (30) servant à raccorder un tuyau à lait (32) transportant un liquide, notamment du lait, à un élément de collecte de lait ou de transport (31) d'une installation de traite, notamment à un seau à lait ou à un tuyau à lait. L'invention concerne également une installation de traite équipée d'un tel dispositif de raccord. Le dispositif de raccord selon l'invention comprend deux éléments de raccord (34, 36) pouvant être reliés l'un à l'autre, un joint d'étanchéité (35, 41) servant à étanchéifier vers l'extérieur un passage (41) des éléments de raccord (34, 36). Les éléments de raccord (34, 36) présentent des moyens de verrouillage (46, 41) coopérant entre eux et servant à réaliser une liaison stable réciproque, l'un des éléments de raccord (34) présentant un segment de réception (33) pour la réception d'un tuyau à lait (32) et l'autre élément de raccord (36) pouvant être relié à l'élément de collecte de lait ou de transport (31). Un espace intérieur du tuyau à lait est coaxial au passage (41) des éléments de raccord (34, 36) lorsque les éléments de raccord (34, 36) sont reliés. Ce faisant, le segment de réception (33) reçoit le tuyau à lait (32) en assurant l'étanchéité aux liquides et le joint d'étanchéité (35, 31) est placé dans le dispositif de raccord (30) de manière à être entouré par l'un des éléments de raccord (34, 36) lorsque les éléments de raccord (34, 36) sont reliés. Avec ce dispositif de raccord, l'invention vise à empêcher qu'un liquide ou que des dépôts de liquide ne pénètrent dans les éléments de raccord (34, 36) et ne s'y fixent. A cet effet, l'un des éléments de raccord (34) pénètre partiellement dans le passage (41) de l'autre élément de raccord (36) lorsqu'ils sont raccordés.
