In addition, the terms "first" and "second" are only used to distinguish in description and have no special meaning.

[0039] The following is based on Figures 1 to 7 The integrated valve group provided by the utility model is introduced.

[0040] As Figures 1 to 2As shown in the embodiment, the integrated valve group mainly comprises a flow channel member 1, a one-way valve, a solenoid valve and a flow channel connector 4. The flow channel member 1 is used to provide a flow channel for confining fluid medium and can be used to mount and fix the one-way valve and the solenoid valve. The one-way valve is used to confine the flow direction of the fluid medium in the flow channel, and the solenoid valve can selectively connect or disconnect the two flow channels, thereby realizing the flow splitting effect. The flow channel connector 4 is mounted on the flow channel member 1 and is used to connect the flow channel member 1 and the device for supplying fluid medium.

[0041] Specifically, as Figure 3 shown in the embodiment, the flow channel member 1 is provided with a first input flow channel 11, a second input flow channel 12 and a first output flow channel 13. The first input flow channel 11 is provided with a first inlet 111 and a second inlet 112 at two ends respectively, and the second input flow channel 12 is provided with a third inlet 121 at one end. The first inlet 111, the second inlet 112 and the third inlet 121 can be used to input different fluid media respectively. The first output flow channel 13 is provided with a first outlet 131 at one end and can be used to output the fluid medium input from the first input flow channel 11 and the second input flow channel 12. The solenoid valve comprises a first solenoid valve 21 and a second solenoid valve 22. The first solenoid valve 21 is connected between the first input flow channel 11 and the first output flow channel 13 and can connect or disconnect the first input flow channel 11 and the first output flow channel 13. The second solenoid valve 22 is connected between the second input flow channel 12 and the first output flow channel 13 and can connect or disconnect the second input flow channel 12 and the first output flow channel 13. The second solenoid valve 22 is arranged closer to the first outlet 131 than the first solenoid valve 21. The one-way valve comprises a first one-way valve 31, which is arranged in the first output flow channel 13 and between the first solenoid valve 21 and the second solenoid valve 22 to control the one-way flow of the fluid medium in the first output flow channel 13 in the direction towards the first outlet 131.

[0042] In order to introduce the function of the integrated valve group conveniently, it is arranged in a cleaning machine and used to clean containers such as glass bottles. In use, the first inlet 111 is connected to a low-pressure gas source, the second inlet 112 is connected to a cleaning agent supply pump, and the third inlet 121 is connected to a high-pressure gas source. As Figure 3 shown, the first solenoid valve 21 is opened and the second solenoid valve 22 is closed, only the first input flow channel 11 and the first output flow channel 13 are connected, and the cleaning agent is input into the first input flow channel 11 through the cleaning agent supply pump. As Figure 4 shown, low-pressure gas is then input into the first input flow channel 11 through the first inlet 111, and the low-pressure gas drives the cleaning agent to be sprayed out of the first outlet 131 at a preset rate, thereby facilitating the internal cleaning of the containers such as glass bottles. After the preliminary cleaning is completed, as Figure 5As shown, stop the input of the cleaning agent and the low-pressure gas, and close the first electromagnetic valve 21 and open the second electromagnetic valve 22, only connect the second input flow channel 12 and the first output flow channel 13, and then input the high-pressure gas from the third inlet 121, after the high-pressure gas is sprayed from the third inlet 121, the container interior can be blown, dried and the like, so that the cleaning is completed.

[0043] Through the integrated valve group, different fluid media can be controlled and efficiently output separately or combined, the electromagnetic valve can avoid the interference between different input flow channels, the one-way valve can further avoid the interference between the high-pressure medium and the low-pressure medium, and the operator only needs to reasonably select the fluid medium input by the inlet, so that the use of multiple fluid media can be realized in a complex process flow by a relatively simple control mode.

[0044] Of course, in some embodiments, only any two of the first inlet 111, the second inlet 112 and the third inlet 121 can be input, and the specific use of the inlet is not limited in the utility model, as long as the integrated valve group has the first inlet 111, the second inlet 112 and the third inlet 121, and can realize the input of three different fluid media.

[0045] Optionally, continuing to refer to Figure 5 As shown, in the embodiment, the flow channel piece 1 is further provided with a second output flow channel 14, one end of the second output flow channel 14 is provided with a second outlet 141, the electromagnetic valve further includes a third electromagnetic valve 23 and a fourth electromagnetic valve 24, and the one-way valve further includes a second one-way valve 32. The third electromagnetic valve 23 is connected between the first input flow channel 11 and the second output flow channel 14, and is used for connecting or disconnecting the first input flow channel 11 and the second output flow channel 14. The fourth electromagnetic valve 24 is connected between the second input flow channel 12 and the second output flow channel 14, and is used for connecting or disconnecting the second input flow channel 12 and the second output flow channel 14. The fourth electromagnetic valve 24 is arranged closer to the second outlet 141 than the third electromagnetic valve 23, and the second one-way valve 32 is arranged in the second output flow channel 14 and between the third electromagnetic valve 23 and the fourth electromagnetic valve 24, so as to control the one-way flow of the fluid medium in the second output flow channel 14 in the direction towards the second outlet 141.

[0046] Through the arrangement of the second output flow channel 14 and the third electromagnetic valve 23, the fourth electromagnetic valve 24 and the second one-way valve 32, the integrated valve group can simultaneously output the fluid medium through the first outlet 131 and the second outlet 141, and can realize the mutual non-interference during the output.

[0047] For example, when the preliminary cleaning is performed, i.e. the first electromagnetic valve 21 is opened and the second electromagnetic valve 22 is closed, the third electromagnetic valve 23 is opened and the fourth electromagnetic valve 24 is closed, the same preliminary cleaning can be performed on another container through the second outlet 141. When the preliminary cleaning of the container connected to the second outlet 141 is completed, the separate blow-drying operation of the second outlet 141 can be realized without interfering with the preliminary cleaning of the container at the first outlet 131 by closing the third electromagnetic valve 23 and opening the fourth electromagnetic valve 24. Similarly, when the preliminary cleaning of the container at the first outlet 131 is completed before the preliminary cleaning of the container at the second outlet 141, the separate blow-drying operation of the first outlet 131 can be realized without affecting the preliminary cleaning of the container at the second outlet 141 by closing the first electromagnetic valve 21 and opening the second electromagnetic valve 22.

[0048] Further, in the present embodiment, the flow passage member 1 is further provided with a third output flow passage 15, one end of the third output flow passage 15 is provided with a third outlet 151, the electromagnetic valves further include a fifth electromagnetic valve 25 and a sixth electromagnetic valve 26, and the one-way valves further include a third one-way valve 33.

The sixth electromagnetic valve 26 is connected between the second input flow passage 12 and the third output flow passage 15, and is used to connect or disconnect the second input flow passage 12 and the third output flow passage 15. The sixth electromagnetic valve 26 is arranged closer to the third outlet 151 than the fifth electromagnetic valve 25, and the third one-way valve 33 is arranged in the third output flow passage 15 between the fifth electromagnetic valve 25 and the sixth electromagnetic valve 26 to control the one-way flow of the fluid medium in the third output flow passage 15 in the direction towards the third outlet 151.

[0049] Similarly to the second inlet 112, by arranging the third output flow passage 15 and the fifth electromagnetic valve 25, the sixth electromagnetic valve 26 and the third one-way valve 33, the integrated valve group can simultaneously output the fluid medium through the first outlet 131, the second outlet 141 and the third outlet 151, and can realize the non-interference during the output.

[0050] Further, in the present embodiment, the one-way valves further include a fourth one-way valve 34 and a fifth one-way valve 35, the fourth one-way valve 34 is connected to the second inlet 112, and the fifth one-way valve 35 is connected to the third inlet 121. The fourth one-way valve 34 and the fifth one-way valve 35 can further prevent the mutual interference between the fluid media of different inlets, and avoid the pollution to the input devices such as the air source and the supply pump.

[0051] Optionally, in the utility model, all the electromagnetic valves are selected to be normally closed electromagnetic valves, so as to ensure that each flow channel is continuously closed in the case of power failure or other abnormal conditions, and leakage is avoided.

The sealing assembly is sealingly arranged between the valve seat and the valve core, and the sealing assembly comprises a polytetrafluoroethylene sealing piece or a rubber sealing piece, which has good high-temperature resistance, high-pressure resistance and corrosion resistance, and can effectively prevent medium leakage.

[0052] As shown in Figure 6 、 Figure 7 In the embodiment, the flow channel piece 1 is made of high-strength aluminum alloy material surface hard anodizing, which has good structural stability and sealing performance. The top surface of the flow channel piece 1 is provided with electromagnetic valve mounting holes for mounting the above-mentioned several electromagnetic valves.
