Abstract
A gas detection system is for detecting the remaining amount of gas in a gas tank that stores a predetermined gas. The gas detection system includes: a gas detector that detects the predetermined gas; and a shutter (e.g., a pressure detector) that is connected between the gas tank and the gas detector and opens and closes a path of the predetermined gas from the gas tank to the gas detector.
Claims12
A gas detection system for detecting a remaining amount of gas in a gas tank that stores a predetermined gas, the gas detection system comprising:
- a gas detector that detects the predetermined gas;
- and
- a shutter that is connected between the gas tank and the gas detector and opens and closes a path of the predetermined gas from the gas tank to the gas detector,
- wherein the shutter includes an open-close valve that opens when a pressure of the predetermined gas is less than or equal to a predetermined pressure,
- the gas detector detects whether or not the predetermined gas is present,
- a communication hole for allowing communication between the gas tank and the gas detector is provided in the open-close valve,
- the gas detection system further comprises:
- an adjuster that adjusts a position of a lid that closes the communication hole, and
- when the gas detector detects the predetermined gas, the adjuster moves the lid toward the open-close valve to close the communication hole.
A gas detection system for detecting a remaining amount of gas in a gas tank that stores a predetermined gas, the gas detection system comprising:
- a gas detector that detects the predetermined gas;
- and
- a shutter that is connected between the gas tank and the gas detector and opens and closes a path of the predetermined gas from the gas tank to the gas detector,
- wherein the gas detector includes:
- one or more release valves for releasing the predetermined gas from the shutter to an outside of the gas detector;
- and
- a controller that controls opening and closing of the one or more release valves, the one or more release valves include:
- a first release valve that opens and closes a path between an internal space of the gas detector and an external space outside the gas detector;
- and
- a second release valve that opens and closes a path between the gas detector and a fuel cell to which the predetermined gas is supplied from the gas tank, and
- the controller opens at least one of the first release valve or the second release valve when the predetermined gas is to be released to the outside of the gas detector.
