Beschreibung
Zusammenfassung:	An air source mechanism is communicated with an air inlet of a two-position five-way electromagnetic valve through an air inlet pipe, an air source switch is arranged on the air inlet pipe, an air outlet of the two-position five-way electromagnetic valve is in parallel connection with a plurality of oil and gas receiving and sending paths through pipelines, and an air inlet of a three-position five-way double-electric-control electromagnetic valve is communicated with a first air outlet of the two-position five-way electromagnetic valve. An air inlet of the three-position five-way knob valve is communicated with a second air outlet of the two-position five-way electromagnetic valve, a first air outlet of the three-position five-way double-electric-control electromagnetic valve is communicated with the first input end of the first shuttle valve, and a second air outlet of the three-position five-way double-electric-control electromagnetic valve is communicated with the first input end of the second shuttle val
