[0053] The main outlet pipe for the medicine is equipped with a first flow meter 40 and a third pressure reducing valve 41.

[0054] After being pressurized, the liquid medicine is stabilized by the third pressure reducing valve 41, then flows through the first flow meter 40 and the second three-way valve 28, and finally mixes with the compressed air at the atomizing nozzle 23 of the chemical rinsing chamber to disinfect the chemical rinsing space and surfaces.

[0058] The second pneumatic diaphragm pump 59 and the first pneumatic diaphragm pump 55 serve as pressurized liquid extraction devices, with one in operation and the other on standby. The seventh pressure switch 53 and the fourth pressure switch 17 monitor the output pressure of the two pneumatic diaphragm pumps, effectively indicating equipment problems caused by pump malfunctions, pipeline blockages, valve malfunctions, etc., thus improving equipment safety. The first, second, third, and fourth chemical branch pipes form an "H" bridge, which facilitates the selection of spray paths, enables multi-path backup, and significantly improves equipment reliability.

The fourth soft water branch pipe is equipped with a third pneumatic valve 43. The first soft water output pipe is equipped with a second flow meter 56 and a third flow meter 58.

[0064] The twelfth ball valve 46 serves as the main valve for soft water supply, connected to the second pressure gauge 45 and the sixth pressure switch 44 for soft water supply display and alarm monitoring. The fourteenth ball valve 50 is a manual water injection valve, installed on the manual water injection branch (third soft water branch pipe). The thirteenth ball valve 48 is followed by the second regulating valve 52 and the sixth solenoid valve 54 in series to form the automatic water injection control branch (first soft water branch pipe). The manual and automatic water injection branches converge and flow into the chemical storage tank 1 via the second flow meter 56 and the third flow meter 58.

A stirrer is installed inside the tank, and a drain outlet is located at the bottom. The first level sensor 2 monitors the high liquid level; when the liquid level is above its installation position, a high-level alarm is triggered. The second level sensor 3 monitors the medium liquid level; when the liquid level is below its installation position, a medium-level alarm is triggered, indicating insufficient chemical solution, and the contaminated side sealing door 25 of the chemical rinsing chamber is locked, preventing personnel from re-entering the chamber for chemical rinsing. The third level sensor 4 monitors the low liquid level; when the liquid level is below its installation position, a low-level alarm is triggered, indicating severe chemical solution shortage, and all sealing doors of the chemical rinsing chamber (including the sealing doors 25 on both the contaminated and clean sides) are locked, preventing personnel from re-entering the chamber.

When the switching directions of the first three-way valve 20, the second three-way valve 28, and the third three-way valve 29 monitored by the first position sensor 27, the second position sensor 30, and the third position sensor 35 are consistent, the emergency agent pipe, the agent output main pipe, and the compressed air delivery pipe of the chemical shower chamber are simultaneously connected to either Chemical Shower One or Chemical Shower Two. The system considers the system reuse selection to be correct, and the currently used chemical shower chamber is Chemical Shower One (or Chemical Shower Two). This achieves time-sharing reuse of the chemical shower system, effectively improving the efficiency of chemical shower use and reducing equipment investment and operating costs.
