first and second high-pressure gas cylinders are connected to first and second inlets of the automatic gas switching valve via first and second pressure reducing valves, respectively;
When the gas pressure difference between the low-pressure outlet sides of the first and second pressure reducing valves becomes larger than a predetermined pressure value, the movable piston of the automatic gas switching valve operates to switch due to the gas pressure difference, and until then the automatic gas switching valve The high-pressure gas cylinder that was supplying gas from the gas supply port of the switching valve is switched to supply from another high-pressure gas cylinder, and the gas pressure is set at each low-pressure outlet side of the first and second pressure reducing valves. In an automatic switching valve device for gas supply, which is equipped with a low-pressure side pressure switch for an alarm that detects when the pressure has dropped to a certain level and prompts replacement of the cylinder, the gas supply automatic switching valve device is provided with a low-pressure side pressure switch that alerts the user to replace the cylinder. is opened by increasing the gas pressure on the outlet side by a small set pressure than the low-pressure side set gas pressure of the pressure reducing valve, and then releases the gas on the same outlet side and lowers the pressure to the above-mentioned low-pressure side set gas pressure. An automatic switching valve device for gas supply with an alarm that is connected to a flexible gas pressure micro-regulator.
