Method and valve arrangement for supplying liquid to a disconnectable element of a coating installation

摘要

The method uses a valve arrangement with valves (6,20) in the atomizer (2) and in the supply part (1), which are closed when the parts are disconnected and opened after connection. After connection, and while the valve in the atomizer is closed, the coupling chamber (11) between the valves is filled with fluid and any air in the chamber is pressed by the fluid from the chamber into a branch channel (34). The connection between coupling chamber and channel is closed, and the fluid flow path (5) into the atomizer is opened.
