In addition, the bottom of the third mounting groove 16 is provided with an adjusting passage 4 with a gradually decreasing opening from top to bottom, and the adjusting passage 4 is used for communicating the third mounting groove 16 and the valve core passage 9. As shown in fig. 1 and 5, the adjustment passage 4 is a tapered passage, and the taper angle of the adjustment passage 4 is 45 °. In another embodiment, the taper angle of the adjustment channel 4 may be 30-60 °.

Wherein, a plurality of first valve mouth subassemblies 12, then the one-by-one configuration is on first mounting groove 2 respectively, and first valve mouth subassembly 12 is provided with the feedstock channel who is linked together with first mounting groove 2. Wherein, a plurality of second valve mouth subassemblies 13, then respectively one-by-one configuration on second mounting groove 3, and second valve mouth subassembly 13 is provided with the discharging channel who is linked together with second mounting groove 3.

Wherein, a plurality of regulating parts 14 are respectively arranged in the third mounting groove 16 in a way of being capable of being adjusted up and down one by one, the regulating parts 14 are provided with matching parts 18 matched with the regulating channel 4, the matching parts 18 are conical geometric bodies matched with the conical channel, and a liquid passing gap 21 is clamped between the matching parts 18 and the regulating channel 4. In the present embodiment, the adjusting member 14 is connected to the third mounting groove 16 by means of screw connection, and the sealing member 15 is sleeved on the adjusting member 14 in a screw manner, wherein the sealing member 15 can seal the matching between the adjusting member 14 and the third mounting groove 16.

In a specific operation process, the adjusting piece 14 can move up and down relative to the valve seat 1 by rotating the adjusting piece 14, so that the size of the liquid passing gap 21 is adjusted. When the liquid passing gap 21 is larger, the liquid amount flowing into the discharging channel from the feeding channel is smaller, and the liquid outlet amount of the discharging channel is smaller. Conversely, the smaller the liquid passing gap 21, the larger the amount of liquid flowing from the feeding channel into the discharging channel, and the larger the amount of liquid flowing out from the discharging channel.

As shown in fig. 2 and 3, in the present embodiment, the upper portion of the adjusting member 14 is provided with an adjusting portion 17 exposed out of the valve seat 1, and the adjusting portion 17 is provided with a friction-increasing pattern, so that the adjusting member 14 can be conveniently driven by the adjusting portion 17 to rotate relative to the valve seat 1, so as to adjust the liquid passing gap 21.

As shown in fig. 1 and fig. 2, in this embodiment, a first backflow cavity 5 and a second backflow cavity 6 that can be communicated with the outside are respectively disposed at two ends of the valve seat 1, and two ends of the backflow channel 8 are respectively communicated with the first backflow cavity 5 and the second backflow cavity 6. Through setting up feeding cushion chamber 10 and ejection of compact cushion chamber 11, can let feeding and ejection of compact process more steady, and then improve the stability that multichannel flow control valve goes out liquid. And through setting up the backward flow chamber, then can let the process of backward flow more steady.

The second valve nozzle assembly 13 includes a second valve nozzle screw-coupled to the second mounting groove 3, and a second nozzle cap screw-coupled to the second valve nozzle. In the present embodiment, the first valve nozzle assembly 12 and the second valve nozzle assembly 13 have the same structure.

As shown in fig. 1 and fig. 2, the multi-channel flow control valve of this embodiment can realize single backflow or double backflow through the backflow channel 8, the first backflow cavity 5, and the second backflow cavity 6 during operation. Specifically, when the first backflow cavity 5 and the second backflow cavity 6 are communicated and flow back to the liquid supply pump body 22, double backflow can be achieved. When one of the return cavities is blocked and the other return cavity is communicated to return to the liquid supply pump body 22, single return can be realized. In this embodiment, the multi-channel flow regulating valve includes a plug 7, and the plug 7 is used for plugging the second backflow cavity 6 to realize single backflow.

Through the above scheme of this embodiment, the multichannel flow control valve of this case can adjust the size of passing liquid clearance 21 through regulating part 14, and then realizes the liquid measure that flows into the discharging channel from the inlet channel. In the multi-channel flow regulating valve, the plurality of regulating parts 14 respectively regulate the corresponding first valve nozzle assemblies 12 and second valve nozzle assemblies 13 one by one, so that the liquid outlet of each discharge channel can be finely regulated, and the multi-channel liquid outlet from the multi-channel flow regulating valve is ensured to have the same liquid outlet flow.

The liquid supply pump 22 is respectively connected to a pair of multi-channel flow control valves, and the multi-channel flow control valves are respectively connected to the injection pump 25, and then the injection pump 25 is used to inject liquid into products such as soft capsules. The injection pump body 25 and the injection pump body 25 belong to the prior art in the field, and are not described herein again.

In the specific working process, the servo motor drives the slide block of the oil supply pump body to do reciprocating motion in the oil supply groove 23. Because the oil supply cavity is a quantitative cavity, the liquid supply amount can be adjusted by adjusting the rotating speed of the servo motor. The liquid passes through the feeding channel, the valve core channel 9 and the discharging channel and then enters the liquid supply pump body. In addition, when the liquid enters the valve core channel 9, a part of the liquid flows into the return channel 8 through the liquid gap 21 and then flows back to the liquid supply pump body 22 through the return cavity and the return port 24. The adjusting member 14 is used for adjusting the amount of the liquid flowing into the return channel 8 through the liquid gap 21, so as to adjust the flow rate of the liquid flowing out from the liquid outlet channel.

Through the scheme of the embodiment, the liquid supply system is provided with the multi-channel flow regulating valve, and when a liquid supply pump body is used for injecting liquid into a plurality of products such as soft capsules, the liquid medicines loaded in the soft capsules are the same. After long-term use, the specific regulating member(s) 14 can be regulated to ensure that the flow rate of each path of liquid discharged from the liquid supply pump body is the same, so as to ensure that the soft capsules are loaded with the same dosage.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
