The automatic distribution station is to connect the intake and suction pipelines between multiple libraries to the distribution station, and then connect the distribution station with ￠110PVC pipeline and ￠8 high-pressure pipe and air conditioning equipment and automatic analyzer. The distribution station has manual valves and butterfly valves imported from Italy. When the analyzer detects that the gas content in the reservoir is higher than the set value, it will issue an instruction to the automatic distribution station to automatically open the automatic butterfly valve in the corresponding reservoir, and then the equipment will automatically start and start the removal procedure. When the program is complete, the equipment stops automatically and the automatic valve in the distribution station closes automatically.
