[0097] The control method of the fluid delivery system provided in this embodiment is specifically in the operation, including the following steps:
[0098] The first step: the fluid delivery target and the supply pipeline complete the cleaning and disinfection, the first intake control unit 1 is held on, and the fluid delivery target cylinder 14 is preparative 0.2-1 bar. The operator opens the "second branch drainage knob", at which time the control of the feed valve 2 and the upper gas roller valve 3 are opened, the feed pipe is required to be reflected at 0.2-1 bar sterile air, and the supply is clean The pipe at the highest point 4 to the second section of the feed valve 2.
[0099] Step 2: Close the "second branch drain knob", at which time the control of the feed valve 2 and the top gas row valve 3 are closed. Open the "climbing drainage cooling knob", at which time the pressure value detected by the conduit pressure sensor 8 is more than 500 mbar, if it is considered to be a sterile air pressure of the pipe, it does not cause the lowest point valve 7 for opening the pipe. The external environment has contaminated risk air inverted the sterile pipe. At this time, the control fluid delivery target feed, bypass valve 5, the lowest point valve 7 is opened, and the rolling section is turned into hot water and continues to blow sterile air cooling. In this case, when the pressure value detected by the pipe pressure sensor 8 is less than 100 mbar, it is determined that the external air inverted tank risk will turn off the pipe minimum point valve 7, which is higher than 500 mbar. So in the pipeline 100-500 mbar sterile air pressure protection, the cooling hot water and blow up the pipe, determine the final row water and blow it to 50 ° C or less according to the pipe length, and the time is time, the time is time, and the feed valve 2 is controlled. The bypass valve 5, the lowest point of the pipe is closed, and the fluid delivery target is allowed to request a signal to the pre-processed transmitting liquid.
[0100] Step 3: When the operator sees that the fluid delivery target is allowed to send the feed request signal to the fluid delivery source 11, the feed request signal is sent to the pre-processing, and the second intake control unit 12 is turned on, and the tank pressure sensor 17 is controlled. When the pressure ≥100 mbar is detected, the control material is discharged from the ground valve 3, the bypass valve 5, the feeding valve 9, the can bottom valve 10 opens, the feed pump 6 delayed 10-60 seconds, re-opening, by fluid delivery source 11 Infeorous air pressure and material are static in pressure, the air pressure pump 6 of the feed valve 9 to the feed pump 6 is to avoid damage to the feed pump 6 when the feed pump 6 is opened. After 10-60 seconds, the feeding pump 6 is turned on, the bypass valve 5 is closed, and the feed pump 6 is discharged from the sterile air from the material top gas row valve 3.
