Abstract
A safety device is provided for a gas distribution system in an airplane, containing at least one pressure regulator (5) between a pressurized gas source (2) and a supply line. Reliability of operation is improved with the provision of a pressure-limiting device (4) with two lines (41, 42) arranged in parallel with two pressure-limiting valves (43, 44, 45, 46) each arranged in the same direction in series. The pressure-limiting device (4) is arranged upstream of the pressure regulator (5).
Claims8
A safety device for a gas distribution system in an airplane, the system comprising:
- a pressurized gas source;
- a supply line;
- a pressure regulator between said pressurized gas source and said supply line;
- a pressure-limiting means comprising two lines arranged in parallel with two pressure-limiting valves each arranged in the same direction in series, said pressure-limiting means being arranged upstream of said pressure regulator.
A method of limiting pressure comprising:
- providing an airplane gas distribution system with a pressurized gas source, a supply line and a pressure regulator between said pressurized gas source and said supply line;
- and
- providing upstream of said pressure regulator two parallel lines each with two pressure-limiting valves arranged in the same direction in series.
An airplane gas distribution system, comprising:
- a pressurized gas source;
- a supply line;
- a pressure regulator between said pressurized gas source and said supply line;
- and
- a pressure-limiting device with two lines arranged in parallel, each line having two pressure-limiting valves arranged in the same direction in series, said pressure-limiting device being arranged upstream of said pressure regulator.
