Pressurized filling system

The utility model belongs to the technical field of filling equipment, and particularly relates to a pressurized filling system. The pressurized filling system comprises a buffer tank, a liquid filling pipe, a plurality of liquid outlet pipes, a pressurized air inlet and a pressure relief opening, wherein the buffer tank is provided with a liquid filling pipe; the filling heads are used for being connected with the corresponding liquid outlet pipes; the air inlet side of the first pressure regulating valve is connected with a compressed air source, and the air outlet side is connected with the pressurized air inlet; the air inlet side of the second pressure regulating valve is connected with the pressure relief opening, and the air outlet side is used for exhausting. The pressurizing and filling system can pressurize the buffer tank, so that high-viscosity liquid can successfully enter the filling head through the liquid outlet pipe for filling; in addition, the liquid flow rate can be adjusted by adjusting t
