System and method for disposing of fluid from a kitchen sink

A vehicle having a system for disposing of fluid from a galley sink, comprising:

• a galley sink for a galley cabin monument of a vehicle;
• a self-regulating valve;
• a control unit;
• a sensor;
• and
• a first signal connection between the sensor and the control unit,
• wherein the input of the self-regulating valve is connected to a first fluid line, which is connected to a drainage opening of the galley sink at least indirectly,
• wherein the self-regulating valve is arranged underneath the drainage opening of the galley sink, such that fluid from the galley sink can flow through the associated drainage opening into the first fluid line,
• wherein the output of the self-regulating valve is configured to be couplable with a source of negative pressure at least indirectly, and
• wherein the self-regulating valve is configured to automatically open at a predetermined first amount M1 of fluid in the first fluid line, such that the self-regulating valve is in an opening state and that fluid can flow out of the first fluid line through the self-regulating valve, and to automatically close at a predetermined second amount M2 of fluid in the first fluid line, such that the self-regulating valve is in a closing state and that the predetermined second amount M2 of fluid remains in the first fluid line as a residual fluid amount,
• wherein the sensor is configured to detect the opening state or the closing state of the self-regulating valve,
• wherein the sensor is configured to transferring a sensor signal, which represents the state of the self-regulating valve to the control unit, and
• wherein the control unit is configured to provide at least one control signal based on the transferred sensor signal.
