INJECTION DISPERSER

摘要

When an injection disperser for injecting and dispersing a main material and a hardening agent through a fine nozzle hole to mix them is installed in a paint flow path on an in-line basis, it is made possible to flow a washing fluid at such a degree of flow rate as to rapidly and reliably wash the paint flow path. An injection disperser (1) has a partition wall (4) for partition into a high pressure side (3H) formed with an inflow port (2in) and a low pressure side (3L) formed with an outflow port (2out), the partition wall (4) being formed with nozzle holes (5...) through which a liquid is injected from the high pressure side (3H) to the low pressure side (3L) so that it is finely divided and dispersed. The partition wall (4) is formed with a washing fluid circulation port (6) whose opening area is wide as compared with the nozzle holes (5...) and is provided with a valve mechanism (V) for opening and closing the circulation port (6).
