[0002] In the pharmaceutical industry, precise flow control and valve management are crucial to ensuring the quality of drugs. As a valve device that can accurately control the fluid flow ratio, the flow ratio control valve plays a key role in the pharmaceutical process.

By manipulating these regulating devices, the opening and closing degree of the one-way valve regulating hole can be changed, thereby achieving the adjustment of the flow ratio.

The adjustment accuracy is low, and the adjustment range of the existing flow ratio control valve is relatively fixed. Therefore, different control valves need to be replaced according to different flow ratios, and the versatility is poor.

[0004] In view of the above problems, the present invention provides a flow ratio control valve to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0036] Reference Figure 1-Figure 5 The present invention provides a technical solution: a flow ratio regulating valve, comprising:

[0037] The valve body 1 has a liquid inlet 2 and a liquid outlet 3 at both ends thereof;

[0038] A sealing disk 4 is fixed on the lower end surface of the valve body 1;

[0039] A connecting plate 5 is fixed on the upper end surface of the valve body 1, and a control ring 6 is fixed on the connecting plate 5, and at least two avoidance grooves 7 are formed on the side wall of the control ring 6;

[0040] A driving device 8, fixed on the upper end surface of the control ring 6;

[0041] The regulating assembly 9 is installed inside the valve body 1 and is connected to the output end of the driving device 8 and is electrically connected to the external control device through the avoidance groove 7;

[0042] Among them, the regulating component 9 includes a sealing component 91, and the sealing component 91 is fixed in the valve body 1. An outer ring 92 is fixed on the sealing component 91. The outer ring 92 and the sealing component 91 divide the valve body 1 into a liquid inlet area and a liquid outlet area. An inner ring 94 is detachably arranged inside the outer ring 92, and a control component 95 is slidably arranged inside the inner ring 94.

[0043] In this embodiment, the side walls of the outer ring 92 and the inner ring 94 are circumferentially provided with a plurality of outer adjustment holes 93 and inner adjustment holes 941, the outer adjustment holes 93 and the inner adjustment holes 941 correspond one to one, and the apertures of the plurality of outer adjustment holes 93 and the inner adjustment holes 941 circumferentially decrease in sequence in a counterclockwise direction.

[0044] That is to say, before using the flow ratio control valve, it is necessary to determine the flow ratio of the liquid, so as to select the outer adjustment hole 93 and the inner adjustment hole 941 of appropriate size to improve the accuracy of the flow ratio control.

[0045] It should be noted that after determining the flow ratio of the liquid, the maximum flow rates of the selected outer adjusting holes 93 and the inner adjusting holes 941 are close to the determined liquid flow ratio. For example, when there are two outer adjusting holes 93 and inner adjusting holes 941 with maximum flow rates of 1:0.5 and 1:0.8 respectively, the liquid flow ratio requirement is determined to be 1:0.3. At this time, the outer adjusting holes 93 and the inner adjusting holes 941 with maximum flow rates of 1:0.5 are selected to facilitate precise adjustment of the flow ratio.

[0046] As a preferred embodiment, the sealing assembly 91 includes:

[0047] A sealing ring 911, sealed and fixed in the valve body 1;

[0048] A plurality of fixing columns 912 are provided and circumferentially fixed to the inner wall of the sealing ring 911;

[0049] A support plate 913, fixed on the plurality of fixing columns 912;

[0050] The magnet 914 is fixed on the upper end surface of the support plate 913 , and a plurality of positioning holes 915 are formed on the magnet 914 . The number of the positioning holes 915 is twice the number of the outer adjustment holes 93 .

[0051] It should be noted that the adsorption force of the magnet 914 needs to be greater than the impact force generated when the liquid flows, so as to improve the positioning effect of the positioning hole 915.

[0052] As a preferred embodiment, the control component 95 includes:

[0053] A sliding post 951 is slidably disposed in the inner ring 94 and connected to the output end of the driving device 8;

[0054] The electromagnet 952 is configured as a plurality of electromagnets 952, which are circumferentially arranged on the lower end surface of the sliding column 951, and the number of the electromagnets 952 corresponds one-to-one to the plurality of inner adjustment holes 941;

[0055] The blocking assembly 953 is configured as a plurality of components, each of which is slidably disposed in the outer adjustment hole 93 and the inner adjustment hole 941 .

[0056] As a preferred embodiment, a wire passing groove is provided inside the sliding column 951, and the electromagnet 952 is connected to an external control device through the wire passing groove and the avoidance groove 7, and a plurality of the electromagnets 952 are controlled individually.

[0057] That is to say, after the flow rate ratio of the liquid is determined, the electromagnet 952 is energized through an external control device so that the electromagnet 952 can adsorb and control the blocking component 953 to be switched, thereby adjusting according to different flow rate ratios.

[0058] As a preferred embodiment, the blocking component 953 includes:

[0059] A plugging head 9531 is slidably disposed in the outer adjustment hole 93 and the inner adjustment hole 941;

[0060] A blocking ring 9533 is fixed on the plugging head 9531 and has a diameter greater than that of the inner adjustment hole 941;

[0061] The connecting rod 9534 has one end hinged on the plugging head 9531 and the other end hinged with an adsorption member 9535 .

[0062] As a preferred embodiment, an adjustment surface 9532 is provided at one end of the sealing head 9531 facing the outer adjustment hole 93 , and two positioning columns 9536 are symmetrically fixed to the bottom of the adsorption member 9535 , and the positioning columns 9536 correspond to the positioning hole 915 .

[0063] It should be noted that the initial state of the adsorption piece 9535 is adsorption through the magnet 914. At this time, the positioning column 9536 is positioned corresponding to the positioning hole 915. When it is needed, the sliding column 951 is made to slide down through the driving device 8 to fit multiple adsorption pieces 9535, and an electromagnet 952 is energized for adsorption through an external control device. Then, the sliding column 951 is moved away from the magnet 914 through the driving device 8. At this time, the adsorption piece 9535 corresponding to the energized electromagnet 952 is adsorbed, thereby driving the sealing head 9531 to slide synchronously through the connecting rod 9534, thereby adjusting the opening and closing degree of the inner adjustment hole 941.

[0064] When the inner ring 94 and multiple sealing components 953 need to be replaced, the multiple adsorption parts 9535 are synchronously adsorbed by the electromagnet 952, so that the multiple sealing heads 9531 enter the inner ring 94, which facilitates the removal and replacement of the inner ring 94 and the sealing components 953.

[0065] Specifically, first, the flow ratio of the liquid is determined, and then multiple sealing components 953 are used to switch according to different flow ratios, thereby improving the versatility of the valve body, and when switching, the electromagnet 952 is energized through an external control device, so that the electromagnet 952 adsorbs the adsorption component 9535 in the sealing component 953 to be switched, and then the sliding column 951 is slid through the driving device 8, and drives the sealing head 9531 to slide, thereby opening and closing the external adjustment hole 93 and the internal adjustment hole 941, and when opening and closing, the flow ratio can be accurately controlled by the distance between the adjustment surface 9532 and the internal adjustment hole 941, that is, by switching multiple sealing components 953 and adjusting the adjustment surface 9532, the control accuracy is greatly improved.

[0066] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
