Abstract
A gas distribution system in an airplane has improved reliability of operation with a first supply line (7) and a second supply line (9) for pressurized gas connected to a pressurized gas source (2) via a branching site (6) with a second shut-off valve (10). The pressure in the supply lines (7, 9) is determined with a pressure-measuring means (24). An evaluating device (24) for the measured pressure signal is provided for sending a closing signal to the shut-off valve (8, 10) of the supply line (7, 9) in which a pressure drop of consequence occurs.
Claims16
An airplane gas distribution system comprising:
- a pressurized gas source;
- a first supply line for pressurized gas;
- a second supply line for pressurized gas;
- a first shut-off valve;
- a second shut-off valve;
- a branching site arranged downstream of said pressurized gas source for said first supply line and for said second supply line, wherein said first supply line is connected via said first shutoff valve to said branching site and said second supply line is connected to said branching site via said second shut-off valve;
- a pressure-measuring means determining the pressure in the supply lines;
- and
- an evaluating device for evaluating a measured pressure signal and for sending a closing signal to the shut-off valve of the supply line causing a pressure drop.
An airplane gas distribution system comprising:
- a pressurized gas source;
- a first supply line for pressurized gas;
- a second supply line for pressurized gas;
- a first shut-off valve;
- a second shut-off valve;
- a branching site arranged downstream of said pressurized gas source for said first supply line and for said second supply line, wherein said first supply line is connected via said first shutoff valve to said branching site and said second supply line is connected to said branching site via said second shut-off valve;
- a pressure-measuring means determining the pressure prevailing in said first supply line and in said second supply line;
- and
- an evaluating device for evaluating a signal based on the pressure prevailing in said first supply line and in said second supply line and for sending a closing signal to the shut-off valve of said first supply line should said second supply line have a diminished prevailing pressure.
