The invention relates to a cock arrangement type (2) that is fitted in the
bottom (1) of a metal casting vessel provided with an opening, comprising a
channel body (3), through which a channel (4) runs, continuing the opening of
the bottom, and the side of which has a rotationally symmetric recess (5) that
extends transversally through the channel (4); and a rotatable closure body
(6) that is fitted in the recess (5) and has a transversal hole (7) at the
depth of the channel (4), the hole closing or opening the channel (4) when the
closure body (6) is rotated. The improvement is achieved so that the end (8)
of the closure body (6) is hinged to the bottom (9) of the recess (5) and that
the contact surface between the closure body (6) and the recess (5) is
rotationally symmetric and smaller than the rotation surface of the recess (5).
L'invention concerne un type de dispositif formant robinet (2) installé dans le fond (1) d'une cuve de coulée de métal dotée d'une ouverture. Ce dispositif comprend un corps de canal (3) dans lequel un canal (4) s'étend dans le prolongement du fond, et dont le côté présente un évidement symétrique rotatif (5) qui s'étend transversalement dans le canal (4) ; et un corps de fermeture rotatif (6)prévu dans l'évidement (5) et doté d'un orifice transversal (7) à la même profondeur que le canal (4), orifice fermant et ouvrant le canal (4) lorsque le corps de fermeture (6) est tourné. L'amélioration consiste en ce que l'extrémité (8) du corps de fermeture (6) est articulée sur le fond (9) de l'évidement (5) et en ce que la surface de contact entre le corps de fermeture (6) et l'évidement (5) est symétrique en rotation et est plus petite que la surface de rotation de l'évidement (5).
