Further, the control device comprises a PLC control module, the input end of the PLC control module is connected with the pressure sensor, and the output end of the PLC control module is connected with the proportional valve.
Through the setting of the PLC control module, the PLC control module is used for logic control and data recording; the PLC control module can be preset with a preset pressure value, and performs analysis and comparison according to the preset pressure value and the pressure sensor feedback data acquired by the preset pressure value so as to perform deviation calculation, thereby effectively performing automatic adjustment control on the proportional valve.
Furthermore, the PLC control module is in communication connection with an HMI module.

Meanwhile, the data condition recorded by the PLC module can be displayed in the HMI module in a chart or curve form, and the information acquisition requirement of a user is met.
Further, a pressure reducing valve is connected between the proportional valve and the argon gas input part.
The argon input from the argon input part is decompressed through the arrangement of the pressure reducing valve, so that the pressure of the argon entering the proportional valve is ensured to be moderate.
