System capable of realizing air pressure control

The utility model discloses a system capable of realizing air pressure control, which comprises an air inlet pipeline and an exhaust pipeline which are communicated with an expansion generator set, and an air inlet stop valve, an air inlet pressure transmitting component, an air inlet flow component, an air inlet temperature transmitter and an air inlet quick stop valve are sequentially arranged on the air inlet pipeline. A check valve, an exhaust stop valve, an exhaust transmitting device and an exhaust temperature transmitter are sequentially arranged on the exhaust pipeline. The system can be used as a gas pressure control and gas recovery system for melting glass. According to the system capable of achieving air pressure control, the expansion generator set is arranged in the mode of the turbo expander, the speed change gear box and the generator, and air pressure difference control is achieved; and the exhaust transmitting device is adopted to control the exhaust pressure of the turbo expander.
