When the temperatures of the disinfecting solutions detected by the first temperature detector 1411 and the second temperature detector 2811 both reach the set value required by disinfecting the disinfecting solutions, the disinfecting solutions are timed, and the disinfecting time of the disinfecting solutions can be determined according to actual needs.
And then, the conveying pipeline is sterilized by superheated water, and meanwhile, the valve cavities of the first cross valve group 10 and the second cross valve group 20 are sterilized by steam. The method comprises the following specific steps.
As shown in fig. 2, the first steam input control valve 310 is opened. In the first valve group 10, the second control valve 12 and the fourth control valve 14 are opened, and the remaining valves are closed. In the second valve group 20, the sixth control valve 26 and the eighth control valve 28 are opened, and the remaining valves are closed. The steam for sterilization enters the steam buffer chamber 31 through the first steam input pipe 311, the steam in the steam buffer chamber 31 enters the first valve chamber 15 from the second control valve 12 through the steam conveying pipe 3, and the steam in the first valve chamber 15 enters the first exhaust pipe 141 through the fourth control valve 14.

During the steam sterilization process, the first and second discharge control valves 1412 and 2812 are intermittently opened to discharge the condensed water. The first and second discharge restrictors 1413 and 2813 are used to assist discharge, respectively.
In the sterilization process, once the temperatures detected by the first temperature detector 1411 and the second temperature detector 2811 are lower than the steam sterilization set value, the timing is suspended until the temperatures detected by the first temperature detector 1411 and the second temperature detector 2811 reach the steam sterilization set value, so that the steam sterilization of the valve cavities of the two cross valve groups is completed.
While steam sterilization is performed, superheated water is fed from the first feed pipe 16, and the superheated water is fed through the first control valve 11, the second feed pipe 17, the fifth control valve 21, and the return pipe 4. The back pressure valve 41 of the return pipe is adjusted to the required back pressure, so that the temperature required by the sterilization of the superheated water in the pipeline can be ensured. The superheated water sterilization time is set according to the actual process requirements. In this manner, the superheated water sterilization was performed. The steam is used for sterilizing the valve cavities of the two cross valve groups, the superheated water is used for sterilizing a conveying pipeline for conveying the sterile water, and the superheated water and the conveying pipeline are parallel and have no conflict.

Thus, a steam shield is formed outside the valve cavities of the two cross valve groups, and the first valve cavity 15 and the second valve cavity 21 are effectively prevented from being polluted again. The first temperature detector 1411 and the second temperature detector 2811 monitor the temperature of the shielding steam in real time, and once the temperature is too low, the system gives an alarm. The shield steam is inputted from the second steam input pipe 321.
After the superheated water is sterilized, the sterile water is input from the first delivery pipe 16, flows back through the first control valve 11, the second delivery pipe 17, the fifth control valve 21 and the return pipe 4, and is input through the first delivery pipe 16, so that the sterile water is continuously self-circulated, and the sterile water is in a standby state capable of being supplied to a use point at any time.

As shown in fig. 5, when a signal for using sterile water from a point of use is received, the first control valve 11 and the third control valve 13 are opened. Sterile water is input from the first conveying pipe 16, the sterile water enters the first valve cavity 11 and the second conveying pipe 17 through the first control valve 11, the sterile water in the first valve cavity 11 enters the first output pipe 7 through the third control valve 13, and the sterile water is conveyed outwards to a using point through the first output pipe 7, so that the supply of the sterile water is realized. The sterile water in the second delivery pipe 17 is returned through the fifth control valve 25 and the return pipe 4.
If simultaneously still other point of use sends aseptic water usage signal, then open fifth control valve 25, seventh control valve 27, aseptic water in the second conveyer pipe 17 gets into back flow 4 and second valve pocket 21 through fifth control valve 25, aseptic water in the second valve pocket 21 gets into second output tube 6 through seventh control valve 27, second output tube 6 is carried aseptic water to another point of use, like this aseptic two cross valves switch conveying mechanism then can provide aseptic water for two points of use simultaneously, this suitability that has improved conveying mechanism greatly to can effectively reduce the cost of whole filling production facility.
