The invention relates to a tool for disintegrating coke, having a housing attached to a drill stem in operation, and at which or in which at least one nozzle for cutting and a nozzle for drilling of coke and at least one valve for closing and opening the nozzles is arranged, wherein said tool is adapted to have two different operating states and wherein said at least one valve closes off said cutting nozzles in the drilling operating state, while the drilling nozzles are closed off by said at least one valve in the cutting operating state, and wherein said housing, said valve and said nozzles are adapted so that water may flow unhindered from said drill stem through said housing and said valve and through the nozzles not closed off by said valve, characterized in that the nozzles to be closed, depending on each chosen operating state, are closed off by the balls of a ball valve. The invention further relates to a tool, wherein the arrangement for operating the valve is arranged above the nozzles.
L'invention concerne un outil pour broyer le coke dans une cage qui, en fonctionnement, est fixée sur une tige de forage et dans laquelle ou contre laquelle sont disposées au moins une buse de coupe, une buse de forage du coke et au moins une soupape pour fermer et ouvrir les buses. Cet outil est conçu pour deux états de marche différents. La soupape, en mode forage, ferme la buse de coupe et, en mode coupe, ferme la buse de forage. La cage, la soupape et les buses sont conçues de telle manière que l'eau peut passer de la tige de forage à travers la cage et la soupape ainsi qu'à travers les buses qui ne sont pas fermées par la soupape. L'invention est caractérisée en ce que, selon le mode de fonctionnement sélectionné, les buses qui doivent être fermées le sont par les billes d'une soupape à billes. La présente invention porte également sur un outil dont le dispositif d'actionnement de la soupape est disposé au-dessus des buses.
