摘要:
Each of the washing units A and B comprises an openable and closable pinch valve unit 4 branchwise connected to a pipeline C, an autofeeder unit 5 for controlling the feed for advance and retraction movement of a high pressure hose 6 having rotatable nozzle unit connected to the front end thereof, and a hose reel unit 7 for winding and unwinding the high pressure hose. During washing operation, the nozzle unit enters the pipeline C through the pinch valve unit 4 now opened to wash the inner surface of the pipeline. During nonwashing period, the nozzle unit is moved rearward and completely isolated from the pipeline by the pinch valve unit 4 now closed. Therefore, the washing units A and B are completely separated from the pipeline C during nonwashing period.
