Abstract
A tank of a gas supply system is configured to be detachably attached to a gas consumption device. A control device is configured to, when the tank is detached, close an open/close valve to stop supply of gas from the tank, stop consumption of gas by the gas consumption device after the gas in the supply channel is consumed, and perform computation to permit detachment of the tank after confirming that pressure acquired from a pressure sensor is not rising to a predetermined level or higher.
Claims6
A gas supply system comprising:
- a gas consumption device;
- a tank that stores gas to be supplied to the gas consumption device, and that is configured to be detachably attached to the gas consumption device;
- and
- a control device, wherein
- the gas consumption device includes a supply channel configured such that the gas flows through the supply channel, and a pressure sensor configured to obtain in-channel pressure of the supply channel,
- the tank is configured to be connected to the supply channel, and is provided with an open/close valve at a portion where the tank is connected to the supply channel, and
- the control device is configured such that, in response to the control device receiving a signal regarding a start of the detachment of the tank, the control device closes the open/close valve to stop supply of gas from the tank, stops consumption of the gas by the gas consumption device after the gas in the supply channel is consumed, and the control device is further configured such that it permits detachment of the tank when the pressure rise is no greater than a predetermined threshold value.
