  • the present invention generally relates to a flow control assembly.
  • the invention relates to a flow control assembly for controlling the flow of a fluid, such as a slurry or paste, relative to a selection of outlets.

La présente invention concerne un ensemble de régulation de débit (11) pour réguler le débit d'un fluide. L'ensemble de régulation de débit comprenant une entrée (19), un tuyau (15) ayant une première extrémité (17) fixée à l'entrée et une seconde extrémité (21) fixée à un corps (23). Le corps est mobile, de telle sorte que la seconde extrémité du tuyau s'aligne avec l'une des quatre stations. Ces quatre stations comprenant une première sortie (30a), une deuxième sortie (30b), une troisième sortie (30c) et une station d'isolement. L'ensemble de régulation de débit comprend également un moyen d'activation (49) pour déplacer le corps par rapport à la première sortie, la deuxième sortie, la troisième sortie, ou la station d'isolation. Le corps est mobile entre la première sortie, la deuxième sortie, la troisième sortie, ou la station d'isolement tandis que le fluide est délivré à l'ensemble de régulation de débit.
