Abstract
A decoking tool includes a valve body equipped with a pressurized fluid inlet and having a plurality of fluid passages, including drilling fluid passages extending substantially the full length of the valve body to conduct fluid to drilling nozzle sockets, and cutting fluid passages extending approximately half as far as the drilling fluid passages to conduct fluid to cutting nozzle sockets, the drilling and cutting fluid passages being disposed alternatingly on a circular locus about an axial centerline of the valve body. There are nozzles installed in the nozzle sockets. A diverter plate is interposed between the valve body and the pressurized fluid inlet and has axial fluid passages disposed on a circular path congruent with the circular locus, the disposition of the axial fluid passages being such that the passages align either with the drilling fluid passages or with the cutting fluid passages of the valve body. Means are provided for rotating the diverter plate to selectively provide fluid communication to either the drilling fluid passages or the cutting fluid passages.
