AI Technical Summary
【0006】 本明細書が開示する別の態様のガス供給システムは、主止弁を備えているガスタンク、ガス供給管、第1流路管、第2流路管、流量調整弁、流路セレクタ、コントローラを備える。ガス供給管はガスタンクのガスをガス利用デバイスに導く。第1流路管は、ガスタンクとガス供給管を接続している。第1流路管には流量調整弁が備えられている。第2流路管は、流量調整弁をバイパスしてガスタンクとガス供給管を接続している。流路セレクタは、ガスタンクのガスの流路を第1流路管と第2流路管の間で切り替える。コントローラは、主止弁を開くとともに第1流路管にガスが流れるように流路セレクタを制御する。コントローラは、ガス供給管の内圧の増加率が所定の増加率上限値を越えないように流量調整弁を制御する。コントローラは、流量調整弁を全開にしてもガス供給管の内圧の増加率が所定の増加率下限値を下回ったら第2流路管にガスが流れるように流路セレクタを制御する。このガス供給システムは、流量調整弁によって、ガス供給管の内圧の増加率を増加率上限値以下に抑えることができる。

Abstract
Claims
1. A gas tank having an automatic shut-off valve that opens when a push rod is pushed in and closes when the push rod is removed, A gas supply pipe having the aforementioned push rod at its tip, which guides the gas from the gas tank to the gas utilization device, An actuator that moves the gas tank forward and backward relative to the push rod, A controller that controls the actuator, It is equipped with, The controller is a gas supply system that adjusts the amount the push rod is pushed into the automatic shut-off valve by the actuator so that the rate of increase of the internal pressure in the gas supply pipe does not exceed a predetermined upper limit of the rate of increase when the automatic shut-off valve is opened by pressing the push rod against the automatic shut-off valve.
2. A gas tank equipped with a main shut-off valve, A gas supply pipe that guides the gas from the aforementioned gas tank to a gas utilization device, A first flow path pipe is connected to the gas tank and the gas supply pipe and is equipped with a flow control valve, A second flow path pipe bypasses the flow control valve and connects the gas tank and the gas supply pipe, A flow path selector that switches the gas flow path of the gas tank between the first flow path pipe and the second flow path pipe, Controller and The controller is equipped with, The main shut-off valve is opened and the flow path selector is controlled so that gas flows through the first flow path pipe. The flow rate control valve is controlled so that the rate of increase in the internal pressure of the gas supply pipe does not exceed a predetermined upper limit of the rate of increase. Even when the flow control valve is fully open, if the rate of increase in the internal pressure of the gas supply pipe falls below a predetermined lower limit of the rate of increase, the flow path selector is controlled so that gas flows into the second flow path pipe. Gas supply system.
