A linear sliding gate valve (10) for a metallurgical vessel comprises a slide plate (20) with a first orifice (30) and a fixed plate (22) with a second orifice (32). A slideable tray (26) supports the slide plate (20) and is arranged to slide the slide plate (20) relative to the fixed plate (22) so as to control an outflow of the metallurgical vessel by the relative position of the first and second orifices (30; 32). The slide plate (20) is rotatable relative to said slideable tray (26). The sliding gate valve further comprises a ratchet mechanism (40; 140) for providing defined angular positions of the slide plate (20). The ratchet mechanism (40; 140) is mounted on the slideable tray (26) such that the slideable tray (26) forms the fixed frame of the ratchet mechanism (40; 140).
La présente invention concerne une soupape à tiroir coulissante linéaire (10) pour un récipient métallurgique comprenant une plaque coulissante (20) munie d~un premier orifice (30) et une plaque fixe (22) munie d~un second orifice (32). Un plateau coulissable (26) supporte la plaque coulissante (20) et est disposé de façon à pouvoir faire coulisser la plaque coulissante (20) par rapport à la plaque fixe (22) de façon à contrôler le flux de sortie du récipient métallurgique à l~aide de la position relative des premier et second orifices (30 ; 32). La plaque coulissante (20) peut tourner par rapport audit plateau coulissable (26). La soupape à tiroir coulissante comprend en outre un mécanisme d~encliquetage (40 ; 140) destiné à fournir des positions angulaires définies de la plaque coulissante (20). Le mécanisme d~encliquetage (40 ; 140) est monté sur le plateau coulissable (26) de façon à ce que le plateau coulissable (26) forme le cadre fixe du mécanisme d~encliquetage (40 ; 140).
