Automatic pressure regulating type high-pressure helium control system

The invention relates to a helium pressure regulating system, in particular to an automatic pressure regulating type high-pressure helium control system. The automatic pressure regulating type high-pressure helium control system comprises a main gas bottle, a high-pressure buffer bottle, a low-pressure buffer bottle, a pneumatic regulating valve, a main gas electromagnetic valve, a high-slow electromagnetic valve, a low-slow electromagnetic valve and a terminal electromagnetic valve, the output port of the main gas bottle is communicated with the input end of the pneumatic regulating valve, the output end of the pneumatic regulating valve is communicated with the input end of the main gas electromagnetic valve, the output port of the high-pressure buffer bottle is communicated with the input end of the high-slow electromagnetic valve, the output port of the low-pressure buffer bottle is connected with the input end of the low-slow electromagnetic valve, and the output ends of the main gas electromagnetic valve, the high-slow electromagnetic valve and the low-slow electromagnetic valve are communicated with the input end of the terminal electromagnetic valve. The automatic pressure regulating type high-pressure helium control system is capable of improving the pressure regulating speed and precision so as to realize the quick, precise and stable pressure output of a high-pressure gas source terminal.
