[0061] The composite filling pipe 9 in the application is a canning discharge port of a sterile carton filling and canning machine. Other types of sterile carton filling and canning machines are connected to the TL reversing valve 6. The working processes of the two types of sterile carton filling and canning machines in several working states are as follows.

[0062] 1. The filling machine with the composite filling pipe is in a standby state, and the filling machine connected to the TL reversing valve 6 is in a production state, as shown in FIG. 2. Figure 2

[0063] 1) The filling machine connected to the TL reversing valve 6: UHT material is input from the valve A inlet and output from the valve B outlet of the TL reversing valve 6, and flows to the filling machine.

[0064] 2) The filling machine with the composite filling pipe is in a standby state and is ready to produce at any time: the left and right steam barriers are simultaneously opened, the right steam enters the steam inlet pipe 100 and is divided into two branches,

[0065] One branch goes downward, passes through the second seat valve 14, one branch goes upward to the right, and the other branch goes leftward to the TL reversing valve 6. The D inlet of the TL reversing valve 6 inputs the C outlet, and the upper passage of the first three-way diaphragm valve 7 inputs the lower passage and outputs the upper passage. The steam can only return downward because the LL reversing valve 10 is in a closed state. Because the lower passage of the first three-way diaphragm valve 7 continuously inputs steam, the pressure is relatively large. After the returning steam enters the upper passage of the first three-way diaphragm valve 7, the steam is discharged to the right through the middle passage. The second thermal resistor 18 is opened, the temperature is greater than 121℃, the water vapor becomes condensate water, and then the condensate water is discharged through the opened sixth seat valve 16 and the second trap 15.

[0066] ​The other branch goes up, through the first seat valve 23, to the LL reversing valve 10. Since the LL reversing valve 10 is closed, the steam goes down, through the first thermal resistor 22, the temperature of which is greater than 121℃, and the water vapor becomes condensed water, which then goes through the opened fifth seat valve 20 and is discharged by the first trap 19;

[0067] The left steam enters through the middle channel of the second three-way diaphragm valve 8, and goes out through the upper channel under the action of gravity, to the two-way diaphragm valve 12. Since the two-way diaphragm valve 12 is closed, the steam goes through the third thermal resistor 11, the temperature of which is greater than 121℃, and the water vapor becomes condensed water, which flows down and then enters through the upper channel of the second three-way diaphragm valve 8, and is discharged through the opened eighth seat valve 3 by the third trap 4.

Since the LL reversing valve 10 is closed, the steam can only return downward. Since the lower channel of the first three-way diaphragm valve 7 continuously enters the steam, the pressure is relatively large. The returned steam enters the upper channel of the first three-way diaphragm valve 7 and then goes out through the middle channel to the right, through the second thermal resistor 18, the temperature of which is greater than 121℃, and the water vapor becomes condensed water, which then goes through the opened sixth seat valve 16 and is discharged by the second trap 15;

[0074] The other branch goes up, through the first seat valve 23, to the LL reversing valve 10. Since the LL reversing valve 10 is closed, the steam goes down, through the first thermal resistor 22, the temperature of which is greater than 121℃, and the water vapor becomes condensed water, which then goes through the opened fifth seat valve 20 and is discharged by the first trap 19;
