Description

Technical Field

[0001] The invention belongs to the technical field of diverter valves and relates to a diverter valve with an adjustable liquid separation ratio function. Background Art

[0002] In the field of industrial fluid control, diverter valves are a common device used to distribute liquid from a single fluid channel to multiple outlets in a certain proportion. Traditional diverter valves usually use a fixed-ratio diverter structure, such as a gear pump or a fixed-aperture diverter. The liquid distribution ratio is determined during manufacturing and cannot be flexibly adjusted during use. However, in actual applications, such as chemical production, pharmaceutical mixing or hydraulic systems, it is often necessary to dynamically adjust the diversion ratio according to process requirements, and traditional diverter valves cannot meet this requirement.

[0003] At present, there are some adjustable diverter valves on the market, which mainly control the liquid separation ratio by adjusting the valve core opening and changing the cross-sectional area of ​​the flow channel. For example, switch valves are installed on two liquid separation pipes respectively, and the liquid separation ratio is controlled by adjusting the opening of the switch valve. However, since the liquid is affected by factors such as resistance, pressure, and fluid properties, it is impossible to ensure that the flow rate is strictly proportional, and the adjustment accuracy is low by simply adjusting the opening of the switch valve.

[0004] Another common flow diversion solution uses a gear pump set, which achieves proportional diversion through a combination of gears of varying displacement. However, the diversion ratio is fixed by the gear size and cannot be adjusted in real time. Changing the ratio requires replacing the gear set, a cumbersome operation and unsuitable for continuous adjustment.

[0005] In addition, since diverter valves are generally installed on pipelines of various types of equipment, the location of the pipelines leads to limitations on the size, power supply and other factors of the diverter valves. Therefore, for the sake of application scenarios and maintenance costs, mechanical valves are used as much as possible.

[0006] In response to the above problems, the present invention proposes an adjustable proportional diverter valve based on a variable tooth chamber liquid dividing wheel structure. By cooperating with the synchronously driven variable tooth chamber gear and the fixed tooth chamber gear, a high-precision, dynamically adjustable diversion function is achieved. At the same time, it has the advantages of compact structure, adaptability to high flow rate conditions, and the ability to work without power supply. Summary of the Invention

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.

[0027] Obviously, the drawings in the following description are only some examples or embodiments of the present application, and for those of ordinary skill in the art, the present application can also be applied to other similar scenarios without making creative efforts on the basis of these drawings. In addition, it can also be understood that although the efforts made in this development process can be complex and lengthy, for those of ordinary skill in the art related to the content disclosed in the present application, some design, manufacturing or production changes on the basis of the technical content disclosed in the present application are only routine technical means and should not be understood as insufficient disclosure of the present application.

[0028] As Figures 1-7 shown, the flow distributor with adjustable liquid distribution proportioning function mainly includes a flow distributor main body 1, a liquid distribution proportioning regulator 2, a proportioning distributor structure 3, a liquid distributor 4, a constant liquid distribution wheel structure 5, a rotating speed synchronizer 6 and an overflow valve 7, and the specific structure and connection relationship are as follows: The diverter valve body 1 is the core structure of the valve body, internally defining a liquid inlet channel 11, a first liquid outlet channel 12, and a second liquid outlet channel 13. The front end of the liquid inlet channel 11 opens to the front surface of the diverter valve body 1, and the rear end forks to connect the front ends of the first and second liquid outlet channels 12 and 13. The rear ends of the two outlet channels open to the rear surface of the diverter valve body 1. Mounting plates 14 are fixed to both sides of the bottom of the diverter valve body 1 to secure the entire structure.

[0029] The liquid distribution ratio regulator 2 is installed on the first liquid outlet channel 12 and consists 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: A threaded knob hole 24 is provided on the top of the upper housing 21, and a transparent observation window 21a is provided on the side; The connecting section 22 connects the upper shell 21 and the lower shell 23 to form a through cavity that is connected to the left and right sides. The right side is connected to the liquid inlet channel 11, and the left side is connected to the first liquid outlet channel 12. A guide groove 25 is provided on the inner wall of the lower shell 23 , the width of which gradually decreases from left to right, and a hole is opened at the bottom for the proportional liquid separation wheel shaft 31 to pass through.

[0030] The proportional liquid separation wheel structure 3 is vertically installed in the liquid separation ratio regulator 2, and includes: The proportional liquid dividing wheel shaft 31 passes through the lower housing 23, and a plurality of annularly arranged fixed gear petals 32 are fixed to the shaft center; The upper sliding gear petal 33 and the lower sliding gear petal 34 are inserted into the gap of the fixed gear petal 32. The sides of the three petals cooperate with the sliding groove through the clamping shoulder 32a to achieve axial sliding and circumferential fixation. A guide post 35 is fixed to the outer surface of the lower sliding gear petal 34. The guide post 35 is embedded in the guide groove 25, and the lower end is pressed against the lower housing 23 by a spring 36. The outer surface of the upper sliding gear petal 33 is provided with a sliding gear outer protrusion 39, which is connected to the lifting member 38 of the screw cap 37. When the screw cap 37 is rotated, the lifting member 38 drives the upper sliding gear petal 33 to move up and down, changing the tooth cavity volume formed with the lower sliding gear petal 34.

[0031] The liquid distributor 4 is mounted within the liquid distribution chamber 13a of the second liquid outlet channel 13 and comprises a liquid distributor wheel 41 and a mating wheel 42 that mesh with each other. The shaft of the liquid distributor wheel 41 is fixedly connected to the second synchronization gear 62, and the lower end of the proportional liquid distributor wheel shaft 31 is fixedly connected to the first synchronization gear 61. The meshing of the first synchronization gear 61 and the second synchronization gear 62 forms a speed synchronizer 6, ensuring that the proportional liquid distributor wheel structure 3 rotates synchronously with the liquid distributor wheel 41.

[0032] Both the first and second liquid outlet channels 12 and 13 are connected to overflow valves 7. Overflow inlet 71 communicates with the liquid outlet channels. Overflow chamber 72 houses an overflow spring 73 and a plug 74. Normally, plug 74 seals overflow inlet 71. When the hydraulic pressure exceeds the limit, the liquid pushes past plug 74 and is discharged through overflow outlet 75.

[0033] The method of using the diverter valve with adjustable liquid separation ratio function of the present invention is as follows: Initial state preparation: Figures 5-12 As shown, the diverter valve body 1 is in a standby state, with the liquid inlet channel 11 connected to the external liquid supply system, and the first and second liquid outlet channels 12 and 13 respectively connected to downstream equipment. The proportional liquid distributor wheel structure 3 in the liquid distribution ratio regulator 2 is in a preset initial position, with the screw cap 37 not yet rotated upward. The lower end of the upper sliding gear petal 33 and the upper end of the lower sliding gear petal 34 abut against each other, with no gear cavity volume between them. The indicator block 38a of the screw cap 37 is aligned with the reference scale on the observation window 21a.

[0034] Determine the liquid separation ratio: Figures 13-15 As shown, the screw cap 37 is rotated upward by a predetermined distance, and the cap column 37b drives the lifting member 38 to move upward through the action of the thread; The lifting member 38 drives the upper sliding gear petal 33 to axially displace through the sliding gear outer protrusion 39; the indicator block 38a moves to the predetermined liquid dispensing ratio scale; The movement of the upper sliding gear flap 33 changes the volume of the tooth cavity between it and the lower sliding gear flap 34. Guided by the guide post 35 and guide slot 25, the lower sliding gear flap 34 adaptively adjusts its position in conjunction with the elastic force of the spring 36. This change in tooth cavity volume directly alters the amount of liquid delivered per single rotation. The size of this tooth cavity volume is pre-calculated when the proportional liquid-dispensing wheel structure 3 is manufactured. The ratio of this tooth cavity volume to the sum of the tooth cavity volumes of the liquid-dispensing wheel 41 and the matching wheel 42 is exactly the ratio indicated by the liquid-dispensing proportional scale. Because the width of the guide slot 25 gradually decreases from left to right, the guide post 35 on the left side of the guide slot 25 can move upward further, allowing the lower sliding gear flap 34 to resist the upper sliding gear flap 33 under the action of the spring 36. However, the guide post 35 on the right side of the guide slot 25 is stuck in the guide slot 25 and cannot move upward. This results in a predetermined tooth cavity volume between the left upper sliding gear flap 33 and the lower sliding gear flap 34.

[0035] Liquid input stage: the working fluid enters from the front end of the liquid inlet channel 11, and when it flows 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 liquid distribution proportional regulator 2, and the other flows to the liquid distribution cavity 13a of the liquid distributor 4. In the liquid distributor 4, the liquid distribution wheel 41 and the matching wheel 42 begin to mesh and rotate under the push of fluid pressure; the liquid enters the second liquid outlet channel 13 through the space between the liquid distribution wheel 41 and the cavity wall of the liquid distribution cavity 13a, and the space between the matching wheel 42 and the cavity wall of the liquid distribution cavity 13a. Since the liquid distribution wheel 41 and the matching wheel 42 are engaged with each other, the liquid in the second liquid outlet channel 13 cannot return to the liquid inlet channel 11. The speed synchronizer 6 ensures that the proportional liquid distribution wheel structure 3 and the liquid distribution wheel 41 maintain completely synchronized rotational speed through the meshing of the first synchronization gear 61 and the second synchronization gear 62. When the proportional liquid distribution wheel structure 3 rotates, the liquid in the liquid inlet channel 11 enters the proportional liquid distribution wheel structure 3 through the tooth cavity between the left upper sliding gear petal 33 and the lower sliding gear petal 34, and then is squeezed out of the tooth cavity by the lower sliding gear petal 34 driven by the spring 36 when the proportional liquid distribution wheel structure 3 rotates to the right end, and enters the first liquid outlet channel 12. In this way, the first liquid outlet channel 12 and the second liquid outlet channel 13 obtain liquid in proportion.

[0036] 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; 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.

[0037] The above-described embodiments are the preferred embodiments of the present application, but the embodiments of the present application are not limited by the above-described embodiments, and any changes, modifications, substitutions, combinations, simplifications made without departing from the spirit and principles of the present application shall be equivalent replacement methods, and shall be included in the protection scope of the present application.
