摘要:PROBLEM TO BE SOLVED: To decrease the number of pipes and to facilitate cleaning in these pipes in disposing a substantial number of the pipes according to the number of tanks at connecting plural pieces of the raw material tanks, mixing tanks and distributing tanks. SOLUTION: The pipes P1 to P6 with control valves 4 and the delivery tanks P11 to P62 are connected to the respective outlet parts 3-1 to 3-6 of a multidirectional valve 1 and the fluid admitted form an inlet section (2) is passed via the multidirectional valve 1 to the necessary pipes P1 to P6 . The flow passage sections of the multidirectional valve 1 have arced flow passages suitable for passing pigs. The pigs are sent from the inlet part 2 of the multidirectional valve 1 and arrive at the respective control valves 4 to clean the pipes P1 to P6 communicating with the assigned outlet parts 3-1 to 3-6. Further, the pigs are returned form the control valves 4 to the inlet part 2 to execute cleaning again.
