As shown in fig. 1, the utility model provides a paper machine hot-blast box cylinder 10 gas circuit system 100, including hot-blast box cylinder 10, fast row valve 20, one-way choke valve 30, solenoid valve 40, exhaust choke valve 50 and air supply 60, hot-blast box cylinder 10 is including pole chamber 11 and no pole chamber 12.
The quick exhaust valve 20 and the one-way throttle valve 30 are sequentially connected with the rodless cavity 12 through an air path, and the quick exhaust valve 20 is further connected with the exhaust throttle valve 50 through an air path. The electromagnetic valve 40 is provided with a first air inlet 41, a first air outlet 42 and an air blocking port 43, the air source 60 is connected with the first air inlet 41 in an air path, and the one-way throttle valve 30 is connected with the first air outlet 42 in an air path. When the electromagnetic valve 40 is energized, the first air inlet 41 is communicated with the first air outlet 42, and at this time, the compressed air released by the air source 60 can be conveyed into the rodless cavity 12 of the hot air box cylinder 10 to support the hot air box cylinder 10 to lift up the hot air box. When the solenoid valve 40 is de-energized, the first air inlet 41 and the first air outlet 42 are disconnected, and the hot air box cylinder 10 stops the lifting action after the air pressure supply of the air source 60 is lost.

The one-way throttle valve 30 is further provided with an intake air flow meter (not shown), and the intake air flow meter can measure the flow rate of the airflow passing through the one-way throttle valve 30. The one-way throttle valve 30 only allows the air flow to flow from the second air inlet 31 to the second air outlet 32 in one way, so as to effectively prevent the air flow in the hot air box cylinder 10 from backflushing the air source 60 to affect the normal operation of the air circuit system. And the one-way throttle valve 30 with adjustable flow is matched with the air inlet flow meter, so that the lifting speed of the hot air box in the jacking process of the air cylinder can be flexibly adjusted.
