TECHNICAL FIELD
[0001] The present application belongs to the technical field of flow dividing valves, and relates to a flow dividing valve with adjustable liquid distribution ratio. BACKGROUND
[0002] In the field of industrial fluid control, flow dividing valves are a common device for distributing liquid in a single fluid channel to multiple outlets in a certain ratio. Traditional flow dividing valves usually adopt fixed-ratio flow dividing structures, such as gear pumps or fixed-aperture flow dividers, whose liquid distribution ratio is determined at the time of manufacture and cannot be flexibly adjusted during use. However, in actual applications such as chemical production, pharmaceutical proportioning or hydraulic systems, it is often necessary to dynamically adjust the flow dividing ratio according to process requirements, and traditional flow dividing valves cannot meet this demand.
[0003] Currently, there are some adjustable flow dividing valves on the market, which mainly achieve control of the liquid distribution ratio by adjusting the valve core opening degree to change the flow passage cross-sectional area. For example, by installing on-off valves on two liquid distribution pipes respectively and adjusting the opening degree of the on-off valves to achieve control of the liquid distribution ratio. However, due to factors such as resistance, pressure and fluid properties, it is impossible to ensure that the flow is strictly proportional, and the adjustment accuracy is low by adjusting the opening degree of the on-off valves alone.
[0004] Another common flow dividing scheme is to use a gear pump set to achieve proportional flow dividing by combining gears of different displacements. However, the liquid distribution ratio is fixed by the gear size and cannot be adjusted in real time. If the ratio needs to be changed, the gear set must be replaced, which is cumbersome and not suitable for continuous adjustment.
[0005] In addition, since flow dividing valves are generally installed on the pipelines of various devices, the pipeline position limits the size and power supply of the flow dividing valve, so it is necessary to use mechanical valves as much as possible for application scenarios, maintenance costs, etc.
[0006] To solve the above problems, the present application proposes an adjustable proportional flow dividing valve based on a variable tooth cavity liquid distribution wheel structure, which cooperates with a variable tooth cavity gear and a fixed tooth cavity gear driven synchronously to achieve high-precision, dynamically adjustable flow dividing function, while having the advantages of compact structure, adaptation to high flow rate conditions, and the ability to work without power supply.

It should be understood that the specific examples described herein are only used to explain the present application and are not used to limit the present application. Based on the examples provided in the present application, all other examples obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present application.

In addition, it can also be understood that although the efforts made in this development process can be complex and lengthy, some design, manufacture or production changes based on the technology disclosed in the present application are only routine technical means for those skilled in the art related to the disclosure of the present application, and should not be understood as insufficient disclosure of the present application.
[0046] As shown in Figures 1-7 The shunt valve with adjustable distribution ratio function of the present application mainly includes a shunt valve body 1, a distribution ratio regulator 2, a proportional distribution wheel structure 3, a distributor 4, a constant distribution wheel structure 5, a rotating speed synchronizer 6 and an overflow valve 7. The specific structure and connection relationship are as follows:
[0047] The shunt valve body 1 is the core structure of the valve body, and has an inlet channel 11, a first outlet channel 12 and a second outlet channel 13 inside. The front end of the inlet channel 11 is open to the front surface of the shunt valve body 1, and the rear end is bifurcated to connect the front ends of the first outlet channel 12 and the second outlet channel 13. The rear ends of the two outlet channels are respectively open to the rear surface of the shunt valve body 1. The bottom of the shunt valve body 1 is fixedly installed with a mounting plate 14 on both sides for overall fixation.
[0048] The distribution ratio regulator 2 is installed on the first outlet channel 12 and is composed of a cylindrical shell and an internal regulating mechanism. The shell includes an upper shell 21, a connecting section 22 and a lower shell 23:
[0049] The upper shell 21 has a threaded knob hole 24 at the top and a transparent observation window 21a on the side;
[0050] The connecting section 22 connects the upper shell 21 and the lower shell 23 to form a through cavity from left to right, with the right side passing through the inlet channel 11 and the left side passing through the first outlet channel 12;
[0051] The inner wall of the lower shell 23 is provided with a guide groove 25, which gradually decreases in width from left to right, and the bottom is provided with an opening for the proportional distribution wheel shaft 31 to pass through.
[0052] The proportional distribution wheel structure 3 is vertically installed in the distribution ratio regulator 2 and includes:
[0053] The proportional distribution wheel shaft 31 penetrates through the lower shell 23, and the shaft center is fixed with a plurality of annularly arranged fixed gear petals 32;
[0054] The upper sliding gear petals 33 and the lower sliding gear petals 34 are inserted into the gaps between the fixed gear petals 32, and the sides of the three are matched with the sliding grooves through the clamping shoulders 32a to realize axial sliding and circumferential fixation;
[0055] A guide post 35 is fixed on the outer surface of the sliding gear 34. The guide post 35 is embedded in the guide groove 25, and its lower end is pressed against the lower housing 23 by a spring 36.
[0056] The outer surface of the upper sliding gear lobe 33 is provided with a sliding gear outer protrusion 39, which is connected to the lifting member 38 of the rotating cap 37. When the rotating cap 37 is rotated, the upper sliding gear lobe 33 is moved up and down through the lifting member 38, changing the tooth cavity volume formed with the lower sliding gear lobe 34.
[0057] The separator 4 is installed in the separating chamber 13a of the second liquid outlet channel 13, and includes a separating wheel 41 and a mating wheel 42 that mesh with each other. The shaft of the separating wheel 41 is fixedly connected to the second synchronous gear 62, and the lower end of the proportional separating wheel shaft 31 is fixedly connected to the first synchronous gear 61. The meshing of the first synchronous gear 61 and the second synchronous gear 62 forms a speed synchronizer 6, ensuring that the proportional separating wheel structure 3 and the separating wheel 41 rotate synchronously.
[0058] Both the first liquid outlet channel 12 and the second liquid outlet channel 13 are connected to overflow valves 7. The overflow inlet 71 is connected to the liquid outlet channel, and the overflow chamber 72 is equipped with an overflow spring 73 and a plug 74. Under normal conditions, the plug 74 seals the overflow inlet 71; when the hydraulic pressure exceeds the limit, the liquid pushes open the plug 74 and is discharged through the overflow outlet 75.
[0059] The method of using the diverter valve with adjustable liquid ratio function of the present invention is as follows:
[0060] Initial state preparation: such as Figures 5-12 As shown, the main body 1 of the diverter valve is in a standby state, the inlet channel 11 is connected to the external liquid supply system, and the first outlet channel 12 and the second outlet channel 13 are respectively connected to the downstream equipment. The proportional distributor wheel structure 3 in the proportional distributor 2 is in the preset initial position. At this time, the rotary cap 37 has not yet rotated upward, the lower end of the upper sliding gear lobe 33 and the upper end of the lower sliding gear lobe 34 are in contact with each other, and there is no tooth cavity volume between them. The indicator block 38a of the rotary cap 37 is aligned with the reference scale on the observation window 21a.
[0061] Determine the separation ratio: such as Figures 13-15 As shown, rotating the cap 37 upwards a predetermined distance causes the cap post 37b to move the lifting member 38 upwards through the thread action;
[0062] The lifting component 38 drives the upper sliding gear disc 33 to move axially via the outer protrusion 39 of the sliding gear; the indicator block 38a moves to the predetermined liquid ratio scale.
[0063] The movement of the upper sliding gear segment 33 changes the volume of the tooth cavity between the upper sliding gear segment 33 and the lower sliding gear segment 34; the lower sliding gear segment 34 is guided by the guide column 35 and the guide groove 25, and is self-adaptively adjusted in position by the elastic force of the spring 36; the change of the volume of the tooth cavity directly changes the liquid delivery amount of a single rotation. The volume of the tooth cavity is calculated in advance when the proportional dispensing wheel structure 3 is manufactured, and the proportion of the volume of the tooth cavity to the sum of the volumes of the tooth cavities of the dispensing wheel 41 and the cooperating wheel 42 is exactly the proportion shown by the dispensing proportion scale. Since the groove width of the guide groove 25 gradually decreases from left to right, the guide column 35 located on the left side of the guide groove 25 can move upward more, and the lower sliding gear segment 34 can resist the upper sliding gear segment 33 under the action of the spring 36, while the guide column 35 located on the right side of the guide groove 25 is clamped by the guide groove 25 and cannot move upward, which leads to that the upper sliding gear segment 33 and the lower sliding gear segment 34 on the left side have a predetermined volume of the tooth cavity.
[0064] Liquid input stage: the working fluid enters from the front end of the liquid inlet channel 11, and when flowing through the bifurcation at the rear end of the channel, the liquid is naturally distributed in two directions: one flows to the through cavity of the dispensing proportion regulator 2, and the other flows to the dispensing cavity 13a of the dispenser 4. In the dispenser 4, the dispensing wheel 41 and the cooperating wheel 42 begin to mesh and rotate under the push of the fluid pressure; the liquid enters the second liquid outlet channel 13 through the space between the dispensing wheel 41 and the cavity wall of the dispensing cavity 13a and the space between the cooperating wheel 42 and the cavity wall of the dispensing cavity 13a, and since the dispensing wheel 41 and the cooperating wheel 42 are engaged with each other, the liquid in the second liquid outlet channel 13 cannot return to the liquid inlet channel 11, and the speed synchronizer 6 ensures that the proportional dispensing wheel structure 3 and the dispensing wheel 41 keep the same speed of rotation through the meshing of the first synchronous gear 61 and the second synchronous gear 62. When the proportional dispensing wheel structure 3 rotates, the liquid in the liquid inlet channel 11 enters the proportional dispensing wheel structure 3 through the tooth cavity between the left upper sliding gear segment 33 and the lower sliding gear segment 34, and then is squeezed out of the tooth cavity by the lower sliding gear segment 34 driven by the spring 36 when the proportional dispensing wheel structure 3 rotates to the right end, thereby realizing the proportional liquid delivery of the first liquid outlet channel 12 and the second liquid outlet channel 13.
[0065] When any outlet pressure abnormally rises, the overflow valve 7 on the corresponding liquid outlet channel is started; the high-pressure liquid overcomes the elastic force of the overflow spring 73, pushes the plug 74 away from the overflow inlet 71, and the excess liquid is discharged from the overflow outlet 75 through the overflow cavity 72. The overflow valve 7 is used for overload protection of the flow divider.
[0066] The embodiments described are the preferred embodiments of the present application, but the embodiments of the present application are not limited by the described embodiments, and any changes, modifications, substitutions, combinations and simplifications made without departing from the spirit and principles of the present application shall be equivalent replacement modes and shall be included in the protection scope of the present application.
