[0037] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0038] Depend on Figures 1 to 5 As shown, this embodiment provides a multi-channel flow control valve, comprising a valve seat 1, a plurality of first valve nozzle assemblies 12, a plurality of second valve nozzle assemblies 13, and a plurality of adjustment members 14. Specifically:

[0039] The valve seat 1 is provided with a plurality of first mounting grooves 2 arranged horizontally and parallelly on the same side, a plurality of second mounting grooves 3 arranged horizontally and parallelly on the same side, a plurality of valve core channels 9 for connecting the first mounting grooves 2 and the second mounting grooves 3 one by one, a plurality of third mounting grooves 16 arranged horizontally and parallelly on the same side and connected one by one to the plurality of valve core channels 9, and a reflux channel 8 horizontally penetrating the valve seat 1 and connected to the plurality of valve core channels 9 respectively. It should be noted that the first valve nozzle assembly 12 and the second valve nozzle assembly 13 are arranged facing each other, the valve core channel 9 is arranged between the first valve nozzle assembly 12 and the second valve nozzle assembly 13, and the third mounting groove 16 is substantially perpendicular to the plane constructed by the first valve nozzle assembly 12 and the second valve nozzle assembly 13.

[0040] In addition, the bottom of the third installation groove 16 is provided with an adjustment channel 4 whose opening gradually becomes smaller from top to bottom, and the adjustment channel 4 is used to connect the third installation groove 16 and the valve core channel 9. Figure 1 and Figure 5As shown, the regulating channel 4 is a tapered channel, and the tapered angle of the regulating channel 4 is 45°. In another embodiment, the tapered angle of the regulating channel 4 may be 30° to 60°.

[0041] Among them, a plurality of first valve nozzle assemblies 12 are respectively arranged one by one on the first mounting groove 2, and the first valve nozzle assembly 12 is provided with a feed channel connected to the first mounting groove 2. Among them, a plurality of second valve nozzle assemblies 13 are respectively arranged one by one on the second mounting groove 3, and the second valve nozzle assembly 13 is provided with a discharge channel connected to the second mounting groove 3.

[0042] Among them, a plurality of adjusting members 14 are respectively arranged in the third mounting groove 16 so as to be adjustable up and down. The adjusting member 14 is provided with a matching portion 18 adapted to the adjusting channel 4. The matching portion 18 is a conical geometric body adapted to the conical channel. A liquid gap 21 is sandwiched between the matching portion 18 and the adjusting channel 4. In this embodiment, the adjusting member 14 is connected to the third mounting groove 16 by a threaded connection. The adjusting member 14 is threadedly sleeved with a sealing member 15, and the sealing member 15 can seal the matching between the adjusting member 14 and the third mounting groove 16.

[0043] In the specific operation process, the adjusting member 14 can be rotated to make the adjusting member 14 move up and down relative to the valve seat 1, thereby adjusting the size of the liquid gap 21. When the liquid gap 21 is larger, the amount of liquid flowing from the feed channel into the discharge channel is smaller, and the amount of liquid discharged from the discharge channel is smaller. Conversely, when the liquid gap 21 is smaller, the amount of liquid flowing from the feed channel into the discharge channel is larger, and the amount of liquid discharged from the discharge channel is larger.

[0044] Depend on Figure 2 and Figure 3 As shown, in this embodiment, the upper part of the adjusting member 14 is provided with an adjusting portion 17 exposed from the valve seat 1, and the adjusting portion 17 is provided with a pattern for increasing friction, so that the adjusting member 14 can be conveniently driven to rotate relative to the valve seat 1 through the adjusting portion 17 to adjust the liquid gap 21.

[0045] Depend on Figure 1 and Figure 2 As shown, in this embodiment, the two ends of the valve seat 1 are respectively provided with a first reflux chamber 5 and a second reflux chamber 6 which can be connected to the outside, and the two ends of the reflux channel 8 are respectively connected to the first reflux chamber 5 and the second reflux chamber 6. By providing a feed buffer chamber 10 and a discharge buffer chamber 11, the feed and discharge processes can be made more stable, thereby improving the stability of the liquid output of the multi-channel flow control valve. By providing a reflux chamber, the reflux process can be made more stable.

[0046] Depend on Figure 1 and Figure 4As shown, in this embodiment, the first valve nozzle assembly 12 includes a first valve nozzle 19 threadedly connected to the first mounting groove 2, and a first nozzle cap 20 threadedly connected to the first valve nozzle 19. The second valve nozzle assembly 13 includes a second valve nozzle threadedly connected to the second mounting groove 3, and a second nozzle cap threadedly connected to the second valve nozzle. It should be noted that, in this embodiment, the structures of the first valve nozzle assembly 12 and the second valve nozzle assembly 13 are the same.

[0047] Depend on Figure 1 and Figure 2 As shown, the multi-channel flow control valve of this embodiment can realize single reflux or double reflux through the reflux channel 8, the first reflux chamber 5 and the second reflux chamber 6 during operation. Specifically, when the first reflux chamber 5 and the second reflux chamber 6 are both connected to reflux to the liquid supply pump body 22, double reflux can be realized. When one reflux chamber is blocked and the other reflux chamber is connected to reflux to the liquid supply pump body 22, single reflux can be realized. In this embodiment, the multi-channel flow control valve includes a plug 7, which is used to block the second reflux chamber 6 to realize single reflux.

[0048] Through the above scheme of this embodiment, the multi-channel flow control valve of this case can adjust the size of the liquid gap 21 through the adjusting member 14, thereby realizing the amount of liquid flowing from the feed channel into the discharge channel. In addition, the multi-channel flow control valve of the present invention has multiple adjusting members 14 that respectively adjust the corresponding first valve nozzle assembly 12 and second valve nozzle assembly 13, so as to realize fine adjustment of the liquid outflow of each discharge channel, thereby ensuring that the multi-channel liquid outflow from the multi-channel flow control valve has the same liquid outflow rate.

[0049] Depend on Figure 6 As shown, this embodiment further provides a liquid supply system, including a liquid supply pump body 22, a pair of multi-channel flow regulating valves, and an injection pump body 25. The liquid supply pump body 22 is provided with an oil supply groove 23, and a reflux port 24 connected to the oil supply groove 23, and the reflux chambers of the pair of multi-channel flow regulating valves are respectively connected to the reflux port 24. Among them, the liquid supply pump body 22 is respectively connected to a pair of multi-channel flow regulating valves, and the pair of multi-channel flow regulating valves are respectively connected to the injection pump body 25, and then the soft capsule and other products are injected with liquid through the injection pump body 25. Among them, the liquid supply pump body 22 and the injection pump body 25 are both existing technical equipment in the field, and will not be repeated here.

[0050] In the specific working process, the servo motor drives the slider of the oil supply pump body to reciprocate in the oil supply groove 23. Since the oil supply chamber is a quantitative chamber, the amount of liquid supplied can be adjusted by adjusting the speed of the servo motor. The liquid passes through the feed channel, the valve core channel 9, the discharge 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 will flow into the reflux channel 8 through the liquid gap 21, and then flow back to the liquid supply pump body 22 through the reflux chamber and the reflux port 24. The regulating member 14 is to adjust the amount of liquid flowing into the reflux channel 8 through the liquid gap 21, thereby adjusting the flow rate of the liquid flowing out of the liquid outlet channel.

[0051] Through the above scheme of this embodiment, the liquid supply system of this case can ensure that the liquid medicine loaded in multiple soft capsules and other products is the same by setting a multi-channel flow regulating valve through the liquid supply pump body. After long-term use, it is also possible to adjust a specific one (some) of the regulating members 14 to ensure that the flow rate of each outlet of the liquid supply pump body is the same, so as to ensure that the amount of medicine loaded in the soft capsule is the same.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
