Abstract

L'invention concerne un outil à libération rapide appliqué à un arbre de vanne d'une vanne papillon électrique et un accouplement. L'outil comprend un élément de positionnement (1) pour fixer un accouplement (2) et une vis d'application de force (4) pour séparer l'accouplement (2) d'un arbre de vanne (3). Une cavité de positionnement (5) et un trou fileté (6) en communication avec la cavité de positionnement (5) sont disposés sur l'élément de positionnement (1). Le côté de la cavité de positionnement (5) opposé au trou fileté (6) comprend une ouverture. La cavité de positionnement (5) et le trou fileté (6) sont disposés coaxialement. La vis d'application de force (4) est reliée de manière filetée dans le trou fileté (6) et peut s'étendre dans la cavité de positionnement (5). Le diamètre de la vis d'application de force (4) est inférieur au diamètre de trou d'un trou central de l'accouplement (2). Au moins un groupe d'éléments de butée est monté sur une paroi de cavité de la cavité de positionnement (5), et chaque groupe d'éléments de butée comprend deux vis de butée (7) disposées à l'opposé l'une de l'autre. L'outil résout le problème de séparation difficile, provoquée par de la corrosion, à une position à laquelle un arbre de vanne et un accouplement sont reliés, améliore l'efficacité de travail de la séparation entre un arbre de vanne et un accouplement, et évite le problème de dommages de l'accouplement provoqués pendant une séparation.
