Description

Technical Field

[0001] This invention relates to the field of splitter technology, and more specifically to an adjustable splitter. Background Technology

[0002] In industrial production and daily applications, precise control of fluid flow rate is crucial for the efficient operation of a system. Traditional flow meters typically have a fixed flow channel design, making it impossible to flexibly adjust the flow rate of gas or liquid according to actual needs. Therefore, for systems with different flow requirements, it is often necessary to select flow meters of different specifications, supplemented by external valves and controllers for regulation. This approach not only increases the complexity of the equipment but also raises costs and maintenance difficulties.

[0003] Existing flow control technologies typically rely on mechanical valves or simple electric controllers to change the opening and closing state of the flow channel; however, these technologies cannot precisely adjust the flow ratio. Furthermore, due to differences in fluid characteristics and pressure conditions across systems, conventional flow meters have poor adaptability to various operating conditions and cannot dynamically adjust the flow rate according to real-time requirements. This limitation is particularly pronounced in applications requiring highly precise control, such as gas analysis and chemical reaction regulation.

[0004] To address these issues, the concept of adjustable flow meters has emerged in recent years, which automatically regulate flow by altering the structure of the fluid channel. However, existing adjustable flow meters are typically complex in structure and have limited adjustment ranges, failing to meet the needs of flow control over a wide range of proportions. Furthermore, accurately adjusting the flow ratio through motor drive and controller remains a significant challenge in current technology. Summary of the Invention

[0005] In order to solve the above-mentioned technical problems, the present invention aims to provide an adjustable flow divider that realizes the function of precisely adjusting the fluid flow rate through an automated drive mechanism. It can dynamically change the channel structure of the flow channel according to different working conditions, thereby achieving flow rate adjustment over a wide range, while reducing the dependence on external valves and additional control equipment.

[0006] This invention is achieved through the following technical solution:

The movable distributor is provided with a guide hole adapted to the guide shaft. The linear motor is disposed in the main body, and the moving end of the linear motor is fixedly connected to the movable distributor and drives the movable distributor to move axially.

[0016] Furthermore, the adjustable diverter also includes a secondary movable diverter, which is movably disposed within the main flow channel, and a gap is provided between the circumferential side surface of the secondary movable diverter and the inner side surface of the main flow channel. The secondary movable diverter has two position states:

[0017] In the first state, the axial side of the secondary moving diverter is in contact with the other axial side of the moving diverter;

[0039] Where there is no conflict, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] Example 1

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an adjustable distributor is provided, including: a main fluid 1, a fixed distributor 2, and a movable distributor 3. The main fluid 1 has a through main channel 11. The fixed distributor 2 is fixedly installed in the main channel 11, and the circumferential side of the fixed distributor 2 is fixedly and sealed to the inner side of the main channel 11. The movable distributor 3 is movably installed in the main channel 11, and a gap is provided between the circumferential side of the movable distributor 3 and the inner side of the main channel 11.

[0042] Specifically, the main fluid 1 is the outer shell of the entire device, with a through-flow main channel 11 inside for fluid passage. A fixed distributor 2 is fixedly installed inside the main channel 11, and its circumferential side is fixedly and sealed to the inner side of the main channel 11, ensuring that fluid can only flow through the flow channel holes within the fixed distributor 2. A movable distributor 3 moves within the main channel 11, with gaps between its circumferential side and the inner side of the main channel 11, allowing fluid to flow through these gaps under certain conditions.

[0043] The fixed flow divider 2 is provided with fixed flow channel holes, and the movable flow divider 3 is provided with movable flow channel holes. The number of fixed flow channel holes is greater than the number of movable flow channel holes.

[0044] The moving splitter 3 has two position states:

[0045] In the first state, the axial side of the movable diverter 3 is in contact with the axial side of the fixed diverter 2. When the movable diverter 3 is in contact with the fixed diverter 2, the fluid can only flow through the flow channel holes in the movable diverter 3. However, since the number of movable flow channel holes is less than that of fixed flow channel holes, some of the fixed flow channel holes are blocked or blocked by the movable diverter 3, and the fluid flow rate is limited, resulting in a small flow rate.

[0046] In the second state, the axial side of the movable diverter 3 is not in contact with the axial side of the fixed diverter 2. When the movable diverter 3 and the fixed diverter 2 are not in contact, the gaps between the movable diverter 3 and the inner wall of the main flow channel 11 are open, allowing fluid to flow through these gaps. At the same time, all the fixed flow channel holes in the fixed diverter 2 are in a connected state. Therefore, the number of channels through which the fluid passes is greatly increased, resulting in a larger flow rate.

[0047] This device regulates fluid flow rate through the axial movement of the movable distributor 3. When the movable distributor 3 is in contact with the fixed distributor 2, only a small portion of the flow channels are connected, reducing the fluid's passage and thus decreasing the flow rate. When they are not in contact, more flow channels are connected, and the fluid can also flow through the gap between the movable distributor 3 and the inner wall of the main flow channel 11, increasing the flow rate. This design enables precise flow control and allows for flexible adjustment according to different operating conditions.

[0048] To ensure good coordination between the fixed distributor 2 and the movable distributor 3, the central axis of the fixed flow channel hole and the central axis of the movable flow channel hole are set parallel or coincident, the central axis of the fixed distributor 2 and the central axis of the movable distributor 3 are set coincident, and the movable distributor 3 moves axially relative to the fixed distributor 2.

[0049] Example 2

[0050] The adjustable diverter achieves precise movement adjustment of the movable diverter 3 by setting the drive component 5 and the control component, thereby changing the flow state of the fluid.

[0051] The adjustable diverter also includes a drive assembly 5 and a control assembly. The drive assembly 5 is disposed in the main fluid 1, and the drive end of the drive assembly 5 is connected to the movable diverter 3 and drives the movable diverter 3 to move axially. The control end of the control assembly is electrically connected to the control end of the drive assembly 5, and the control assembly controls the movable diverter 3 to be in a first state or a second state.

[0052] The drive assembly 5 includes a micro drive motor 53, a drive gear 52, and a guide shaft 51. The guide shaft 51 is vertically fixed to the axial side of the fixed distributor 2. The movable distributor 3 is provided with a guide hole adapted to the guide shaft 51. The circumferential side of the movable distributor 3 is provided with a helical tooth pattern adapted to the drive gear 52. The micro drive motor 53 is disposed in the main fluid 1, and its torque output shaft is connected to the drive gear 52, driving the movable distributor 3 to rotate.

[0053] The function of the micro drive motor 53 is to provide torque. It is connected to the drive gear 52 through its output shaft. The drive gear 52 meshes with the helical teeth set on the movable splitter 3. The helical teeth enable the movable splitter 3 to have an axial movement force when rotating, ensuring that the movable splitter 3 moves along a predetermined axial path.

[0054] The number of miniature drive motor 53 and drive gear 52 is at least one. The guide hole of the movable diverter 3 coincides with the central axis of the movable diverter 3, and the guide shaft 51 coincides with the central axis of the fixed diverter 2 to ensure that no offset or error occurs during the movement.

[0055] The control component controls the drive component 5 via electrical connection. Its main function is to control the movable distributor 3 to be in either the first or second state as needed. The control component can precisely control the axial engagement or disengagement of the movable distributor 3 with the fixed distributor 2 by starting, stopping, and reversing the motor.

[0056] When the control component issues a command (the control button can be located on the outer casing of the main fluid 1), the micro drive motor 53 starts, driving the rotation of the movable distributor 3 via the drive gear 52. The movable distributor 3 moves axially along the guide shaft 51. According to the control command (the specific rotation time and rotation angle can be set in advance), the movable distributor 3 can be driven to the first state (fitted with the fixed distributor 2, with some flow channel holes blocked, achieving a small flow rate) or the second state (separated from the fixed distributor 2, with the fluid passing through all flow channel holes and the gap between the movable distributor 3 and the main flow channel 11, achieving a large flow rate).

[0057] Example 3

[0058] This embodiment provides another possible structure for the drive component 5.

[0059] The adjustable diverter also includes a drive assembly 5 and a control assembly. The drive assembly 5 is disposed in the main fluid 1, and the drive end of the drive assembly 5 is connected to the movable diverter 3 and drives the movable diverter 3 to move axially. The control end of the control assembly is electrically connected to the control end of the drive assembly 5, and the control assembly controls the movable diverter 3 to be in a first state or a second state.

[0060] The drive assembly 5 includes a linear motor and a guide shaft 51. The guide shaft 51 is vertically fixed to the axial side of the fixed distributor 2. The movable distributor 3 is provided with a guide hole that matches the guide shaft 51. The linear motor is located inside the main fluid 1, and the moving end of the linear motor is fixedly connected to the movable distributor 3 and drives the movable distributor 3 to move axially.

[0061] Unlike traditional rotary motor drives, linear motors directly generate linear motion. Their moving end is fixedly connected to the moving distributor 3, driving it to move smoothly along the axial direction. This linear motion method reduces complex gear transmission structures, simplifies the mechanical design of the device, and improves the accuracy of movement and the response speed of control.

[0062] The control component enables real-time control of the drive component 5 via electrical connection. The control component controls the start, stop, and direction of movement of the linear motor through electrical signals, thereby controlling the moving distributor 3 to be in either the first or second state.

[0063] Alternatively, the linear motor can be replaced with a transmission structure capable of linear motion, such as an electric telescopic rod or a threaded screw structure.

[0064] Example 4

[0065] In this embodiment, the introduction of a two-stage moving splitter further enhances the flow regulation capability of the splitter system, and achieves more precise flow control through a multi-stage structural design.

[0066] The adjustable diverter also includes a secondary movable diverter, which is movable within the main flow channel 11, and a gap is provided between the circumferential side of the secondary movable diverter and the inner side of the main flow channel 11. The secondary movable diverter has two position states:

[0067] In the first state, the axial side of the secondary moving diverter is in contact with the other axial side of the moving diverter 3. When the secondary moving diverter is in contact with the axial side of the moving diverter 3, the fluid can only pass through the secondary moving flow channel orifice, while the other flow channel orifices of the moving diverter 3 are partially or completely blocked. Due to the smaller number of secondary moving flow channel orifices, the fluid flow rate is further reduced, resulting in a smaller flow output.

[0068] In the second state, the axial side of the secondary moving splitter is not in contact with the other axial side of the moving splitter 3; when the secondary moving splitter is separated from the moving splitter 3, more flow channel holes, including the flow channel holes of the moving splitter 3, are opened, and the first state of the moving splitter 3 in Embodiment 1 can be executed.

[0069] The secondary moving flow divider is equipped with secondary moving flow channel holes, and the number of moving flow channel holes is greater than the number of secondary moving flow channel holes.

[0070] The central axis of the moving flow channel hole and the central axis of the secondary moving flow channel hole are set parallel or coincident. The central axis of the moving flow divider 3 and the central axis of the secondary moving flow divider are set coincident. The secondary moving flow divider moves axially relative to the moving flow divider 3.

[0071] This embodiment introduces a two-stage moving flow divider to form a multi-stage flow channel regulation mechanism, which can further refine the flow rate regulation range. With the combined action of the two-stage flow dividers, the fluid flow rate regulation can not only achieve significant control but also achieve a more precise regulation effect.

[0072] Similarly, after introducing the secondary moving splitter, a corresponding secondary drive component needs to be configured. The secondary drive component is set in the main fluid 1, and the drive end of the secondary drive component is connected to the moving splitter 3, driving the secondary moving splitter to move axially. The control end of the control component is electrically connected to the control end of the secondary drive component, and the control component controls the secondary moving splitter to be in the first state or the second state.

[0073] For the selection of secondary drive components, please refer to Embodiments 2 and 3.

[0074] Example 5

[0075] To achieve more precise and wider-range flow regulation, an n-stage moving distributor is configured, where n > 2. The number of flow channel orifices in each stage of the distributor decreases progressively, allowing for precise adjustment of the fluid flow rate within a smaller increment. This multi-stage distributor design enables the system to progressively reduce the fluid flow rate under different conditions, providing continuous regulation capability from high flow rates to extremely low flow rates.

[0076] The specific structure of the n-stage moving splitter can be set by referring to the structure of the two-stage moving splitter.

[0077] The n-stage moving splitter is movable within the main flow channel 11, and a gap is provided between the circumferential side of the n-stage moving splitter and the inner side of the main flow channel 11. The n-stage moving splitter has two position states:

[0078] In the first state, the axial side of the n-stage moving splitter is in contact with the other axial side of the n-1-stage moving splitter;

[0079] In the second state, the axial side of the n-stage moving splitter does not fit with the other axial side of the n-1-stage moving splitter;

[0080] The n-stage moving flow divider has n-stage moving flow channel holes, and the number of n-1 stage flow channel holes is greater than the number of n-stage moving flow channel holes.
