Summary:The utility model relates to the technical field of sterile filling, and discloses a control system for backpressure of a filling machine, which comprises a sterile material tank connected with an airinlet pipe and an air outlet pipe. The system further comprises a constant-pressure valve, an air inlet proportional control valve, an air outlet proportional control valve, a pressure detection device and a controller. The constant pressure valve is arranged on the air inlet pipe; the air inlet proportion adjusting valve is arranged on the air inlet pipe; the exhaust proportion regulating valveis arranged on the exhaust pipe; the pressure detection device can detect the pressure of sterile back pressure gas in the sterile material tank; the air inlet proportion adjusting valve, the air outlet proportion adjusting valve and the pressure detection device are all electrically connected with the controller. The constant-pressure valve preliminarily stabilizes the pressure of the air inlet pipe, the pressure detectio
