FIELD: chemistry.
SUBSTANCE: invention relates to chemical industry. Switching device with remote control interacts with instrument (300) and liquid for decoking in first working mode to set drilling mode with application of one or several drilling nozzles of instrument, in second working mode to set cutting mode with application of one or several cutting nozzles of instrument. In one version device contains one or several sets of successive sealings, located along the boundary of component separation inside device or between device and instrument. In other version device contains gas spring for counteraction of forces, applied due to liquid for decoking which has higher pressure. In third version device contains connection for manual overriding.
EFFECT: invention makes it possible to improve remotely controlled device in cutting mode for application with combined instrument for decoking.
