The inlet pipe 21 is fixed on the upper part of the support frame 17, and mounting holes are opened at the lower corners of the support frame 17.

[0028] The four-way gas flow control device can achieve precise flow control of four different gases and mix and output these gases as required.

Among them, in the control component 1, the control box 11 is the core part of the whole device, which is built-in with a controller and a signal processing circuit for processing data from sensors and controlling the actions of the electromagnetic control valve 13. The electromagnetic control valve 13 is embedded at the end of the control box 11 for controlling the on-off of the gas in the gas path. The signal box 12 is fixed on the upper side of the control box 11, which is built-in with a communication module and is provided with a communication interface to support connection with other devices.
