Gas supply system

摘要

A gas supply system that supplies a gas after making confluence of the gas flows from gas containers includes: a supply pressure detector that detects supply pressure of the gas following the confluence; and a controller that permits a gas supply-destination apparatus to be activated if the supply pressure detected after an elapse of a determination time from a start of the gas supply is greater than or equal to a threshold pressure, and that prohibits the apparatus from being activated if the supply pressure is less than the threshold pressure. The controller uses a first determination time as the determination time if it is determined that internal pressures that are the gas pressures in the containers are not imbalanced between the containers, and uses a second determination time that is longer than the first as the determination time if it is determined that the internal pressures are imbalanced.

1. A gas supply system that supplies a gas after making confluence of flows of the gas from a plurality of gas containers in which the gas is contained, comprising:
a supply pressure detector that detects supply pressure that is a post-confluence pressure of the gas that occurs following the confluence in a supply channel of the gas; and a controller that permits a gas supply-destination apparatus to which the gas is supplied to be activated if the supply pressure detected by the supply pressure detector at a time point of elapse of a predetermined determination time following a time point at which the gas starts to be supplied is greater than or equal to a predetermined threshold pressure, and that prohibits the gas supply-destination apparatus from being activated if the supply pressure detected at the time point of elapse of the predetermined determination time is less than the threshold pressure, wherein the controller uses a first determination time as the determination time if it is determined that internal pressures each of which is pressure of the gas contained in a corresponding one of the plurality of gas containers are not imbalanced between the plurality of gas containers, and uses a second determination time that is longer than the first determination time as the determination time if it is determined that the internal pressures of the plurality of gas containers are imbalanced between the plurality of gas containers.
