FLUID VALVE, IN PARTICULAR A RETURN VALVE FOR A PAINTING SYSTEM

摘要

Exemplary illustrations of a fluid valve, e.g., a return valve for returning residual paint, rinsing agent, and compressed air from a paint line when changing color in a painting system, are disclosed. An exemplary fluid valve may be adjusted between an open position, in which the fluid valve is at least partially open, e.g., for rinsing a paint line with a rinsing agent and for pressurizing the paint line with a new color for the color change, and a closed position, in which the fluid valve is closed, e.g., for applying the new color after the color change. An exemplary fluid valve may switch to the closed position, upon actuation by the medium thereof, e.g., medium flowing through or present in the valve. In another example, a fluid valve may close depending on the fluid present at the input side.

1. A fluid valve (8), in particular a return valve (8) for returning residual color, flushing agent, air and/or compressed air from a color line (5) during a color change in a painting system (1), in particular during loading o f a new color during a color change, with
a. an opening position in which the fluid valve (8) is at least partially open, in particular for flushing the color line (5) with flushing agent and for loading the color line (5) with new color during the color change, and b. a closing position in which the fluid valve (8) is closed, in particular for applying the new color after the color change, c. wherein the fluid valve (8) is adjustable between the opening position and the closing position,characterized in that
d. the fluid valve (8) switches dependent on the fluid present on the inlet side own medium actuated to the closing position and/or influences the through flow behavior dependent on the fluid present on the inlet side own medium actuated.
