Referring to fig. 5, when the gas pressure in the second gas delivery device 11 is lower than the preset gas pressure, that is, the gas in the second gas delivery device 11 cannot meet the gas demand of the gas utilization device 12, at this time, although the gas is still being supplied from the second gas tank 111, the gas pressure of the gas delivered from the second gas tank 111 is already insufficient, and since the gas is already replenished in the first gas tank 101, the first pressure regulating valve 102 is opened, so that the first gas tank 101 delivers the gas to the gas utilization device 12, thereby ensuring that the gas is uninterruptedly supplied to the gas utilization device 12, and thus the gas utilization device 12 maintains the preset gas pressure and continuously operates. Finally, referring to fig. 6, when the gas pressure of the gas in the gas using device 12 is maintained at the preset gas pressure, the second pressure regulating valve 112 is closed to stop the gas supply of the second gas tank 111, and the gas is supplemented to the second gas tank 111 to meet the demand of the subsequent gas use.

It should be noted that the preset gas pressure refers to a gas pressure required by the gas using device 12 to enter the gas using device 12, and when the gas pressure of the gas entering the gas using device 12 is lower than the preset gas pressure, the gas using device 12 cannot perform the production operation normally. The preset air pressure may be 7MPa, 8MPa, 9MPa, 10MPa, etc., as long as the normal operation of the air-using device 12 is satisfied, and the application is not limited thereto.

Further, the gas continuous delivery system further comprises: a first pressure sensor 13, a second pressure sensor 14, and a controller 15. The first pressure sensor 13 is electrically connected to the first pressure regulating valve 102 to detect a first pressure signal of the gas output from the first gas tank 101; the second pressure sensor 14 is electrically connected to the second pressure regulating valve 112 to detect a second gas pressure signal of the output gas of the second gas tank 111; the controller 15 is electrically connected to the first pressure sensor 13 and the second pressure sensor 14, respectively, and acquires a first air pressure signal and a second air pressure signal.
Since the first pressure sensor 13 is electrically connected to the first pressure regulating valve 102, and the controller 15 is electrically connected to the first pressure regulating valve 102, the first pressure sensor 13 can detect a first pressure signal of the gas output from the first gas tank 101 in real time, and the controller 15 can also quickly obtain the first pressure signal detected by the first pressure sensor 13. Also, since the second pressure sensor 14 is electrically connected to the second pressure regulating valve 112, and the controller 15 is electrically connected to the second pressure regulating valve 112, the second pressure sensor 14 can detect the second air pressure signal of the output air of the second air tank 111 in real time, and the controller 15 can also quickly acquire the second air pressure signal detected by the second pressure sensor 14.
Thus, when the air pressure of the gas in the first gas delivery device 10 is lower than the preset air pressure, the controller 15 will quickly control the second pressure regulating valve 112 to open, so that the second gas tank 111 can quickly supply gas to ensure that the gas continuously enters the gas using device 12, and the gas using device 12 operates according to the preset air pressure; when the gas pressure of the gas in the gas using device 12 is maintained at the preset gas pressure, since the gas in the first gas tank 101 is already seriously insufficient at this time, the controller 15 may control the first pressure regulating valve 102 to close, so as to supplement the gas to the first gas tank 101 in time to meet the demand of subsequent gas use. Similarly, when the gas pressure of the gas in the second gas delivery device 11 is lower than the preset gas pressure, the controller 15 will also quickly control the first pressure regulating valve 102 to open, so that the first gas tank 101 supplemented with the gas can quickly supply the gas, so as to ensure that the gas continuously enters the gas using device 12, and the gas using device 12 operates according to the preset gas pressure; when the air pressure of the gas in the gas using device 12 is kept at the preset air pressure, the controller 15 may rapidly control the second pressure regulating valve 112 to close, so as to supplement the gas to the second gas tank 111 in time to meet the demand of subsequent gas use.
In summary, since the controller 15 and the pressure sensor are electrically connected to the pressure regulating valve, the air pressures in the first gas delivery device 10 and the second gas delivery device 11 can be quickly obtained, so as to conveniently open or close the first pressure regulating valve 102 and the second pressure regulating valve 112 in time, that is, the first gas delivery device 10 and the second gas delivery device 11 can be quickly switched to meet the requirement of uninterruptedly delivering gas to the gas utilization device 12.

For example, when the air pressure output by the first air tank 101 is lower than the preset air pressure and the first pressure regulating valve 102 is closed, the operator may quickly know that the air pressure output by the first air tank 101 is insufficient, and replace the first air tank 101 in time or use the inflator 18 to replenish the first air tank 101; when the air pressure output by the second air tank 111 is lower than the preset air pressure and the second pressure regulating valve 112 is closed, the operator can quickly know that the air pressure output by the second air tank 111 is insufficient, and timely replace the second air tank 111 or supplement air to the second air tank 111.
In other embodiments, the gas continuous delivery system further comprises an alarm 17. Wherein, alarm 17 is connected with controller 15 electricity, and when the atmospheric pressure of first gas pitcher 101 output was less than preset atmospheric pressure, and/or the atmospheric pressure of second gas pitcher 111 output was less than preset atmospheric pressure, controller 15 was used for sending warning signal to alarm 17, and alarm 17 receives warning signal to report to the police, is convenient for remind operating personnel in time to first gas pitcher 101 or second gas pitcher 111 make-up gas.

When the controller 15 controls the first pressure regulating valve 102 to close, the controller 15 is used for controlling the inflator 18 to supplement the gas to the first gas tank 101; when the controller 15 controls the second pressure regulating valve 112 to be closed, the controller 15 is configured to control the inflator 18 to replenish the gas to the second gas tank 111.
When the controller 15 controls the first pressure regulating valve 102 to close, the gas pressure in the first gas tank 101 cannot be used, and at this time, the controller 15 timely controls the inflator 18 to automatically replenish gas into the first gas tank 101, so that the first gas tank 101 can be replenished quickly, and when the gas delivered by the second gas tank 111 cannot meet the preset gas pressure, the first gas tank 101 is used for delivering the gas uninterruptedly; similarly, when the controller 15 controls the second pressure regulating valve 112 to close, the pressure of the gas in the second gas tank 111 is not enough to be used, and at this time, the controller 15 may timely control the inflator 18 to automatically replenish the gas into the second gas tank 111, so as to quickly replenish the gas into the second gas tank 111, so as to use the second gas tank 111 to continuously deliver the gas when the gas delivered by the first gas tank 101 cannot meet the preset gas pressure. In this manner, the period for replenishing the first gas tank 101 and the second gas tank 111 with gas can be shortened, facilitating quick switching of the first gas tank 101 and the second gas tank 111 for uninterrupted gas supply.
