Description

Technical Field

[0001] The invention relates to the technical field of shunts, and in particular to an adjustable shunt. Background Art

[0002] In industrial production and daily applications, precise control of fluid flow is essential for the efficient operation of the system. Traditional flow meters usually have a fixed flow channel design and cannot flexibly adjust the flow rate of gas or liquid according to actual needs. Therefore, for systems with different flow requirements, flow meters of different specifications are often required, supplemented by external valves and controllers for adjustment. This solution not only increases the complexity of the equipment, but also increases the cost and maintenance difficulty.

[0003] Existing flow control technologies usually rely on mechanical valves or simple electric controllers to change the opening and closing state of the flow channel. However, these technologies cannot accurately adjust the flow ratio. In addition, due to the different fluid characteristics and pressure conditions of each system, conventional flow meters have poor adaptability under different working conditions and cannot dynamically adjust the flow according to real-time needs. This limitation is particularly evident in applications that require highly precise control, such as gas analysis and chemical reaction regulation.

[0004] In order to deal with these problems, the concept of adjustable flowmeter has gradually emerged in recent years, which realizes automatic flow adjustment by changing the structure of the fluid channel. However, the existing adjustable flowmeters are usually complex in structure and have a limited adjustment range, which cannot meet the flow control needs within a large ratio range.

[0028] In the absence of conflict, the embodiments and features of the embodiments of the present invention may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Embodiment 1

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an adjustable diverter is provided, comprising: a main fluid 1, a fixed diverter 2 and a movable diverter 3, a main fluid 1 having a main channel 11 therethrough, the fixed diverter 2 being fixedly arranged in the main channel 11, and a circumferential side surface of the fixed diverter 2 being fixedly sealed and connected to an inner side surface of the main channel 11, the movable diverter 3 being movably arranged in the main channel 11, and a gap being arranged between the circumferential side surface of the movable diverter 3 and the inner side surface of the main channel 11.

[0031] Specifically, the main flow device 1 is the outer shell of the entire device, and a main flow channel 11 is provided inside for the passage of the fluid. The fixed flow divider 2 is fixedly arranged in the main flow channel 11, and its circumferential side surface is fixedly sealed and connected with the inner side surface of the main flow channel 11, ensuring that the fluid can only flow through the flow channel hole in the fixed flow divider 2. The mobile flow divider 3 moves in the main flow channel 11, and there is a gap between its circumferential side surface and the inner side surface of the main flow channel 11, allowing the fluid to flow through these gaps under certain conditions.

[0032] Fixed flow channel holes are arranged in the fixed flow divider 2, and movable flow channel holes are arranged in the movable flow divider 3, and the number of the fixed flow channel holes is greater than the number of the movable flow channel holes.

[0033] The mobile diverter 3 has two position states: In the first state, the axial side of the mobile flow diverter 3 is in contact with the axial side of the fixed flow diverter 2; when the mobile flow diverter 3 is in contact with the fixed flow diverter 2, the fluid can only flow through the flow channel holes in the mobile flow diverter 3. However, since the number of mobile flow channel holes is less than that of fixed flow channel holes, some of the fixed flow channel holes are blocked or clogged by the mobile flow diverter 3, and the fluid flow rate is limited at this time, showing a small flow rate.

[0034] In the second state, the axial side of the mobile diverter 3 does not fit the axial side of the fixed diverter 2; when the mobile diverter 3 does not fit the fixed diverter 2, the gap between the mobile diverter 3 and the inner wall of the main flow channel 11 is open, and the fluid can flow through these gaps, and all the fixed flow channel holes in the fixed diverter 2 are in a connected state. Therefore, the channels through which the fluid passes are greatly increased, the flow rate is increased, and it is manifested as a large flow rate.

[0035] The device achieves fluid flow regulation through the axial movement of the mobile diverter 3. When the mobile diverter 3 fits with the fixed diverter 2, only a small number of flow channel holes are connected, the passage through which the fluid passes becomes smaller, and the flow rate decreases; when the two do not fit, more flow channel holes are connected, and the fluid can also flow through the gap between the mobile diverter 3 and the inner wall of the main channel 11, and the flow rate increases. This design can achieve precise control of the flow rate and flexibly adjust it according to different working conditions.

[0036] In order to ensure that the fixed diverter 2 and the mobile diverter 3 have good coordination, the central axis of the fixed flow channel hole and the central axis of the mobile flow channel hole are arranged in parallel or coincidently, the central axis of the fixed diverter 2 and the central axis of the mobile diverter 3 are arranged to coincide, and the mobile diverter 3 moves axially relative to the fixed diverter 2.

[0037] Embodiment 2

[0038] The adjustable flow divider realizes precise movement and adjustment of the movable flow divider 3 by setting a driving component 5 and a control component, thereby changing the flow state of the fluid.

[0039] The adjustable diverter also includes a driving component 5 and a control component. The driving component 5 is arranged in the main fluid 1, and the driving end of the driving component 5 is connected to the mobile diverter 3, and drives the mobile diverter 3 to move axially. The control end of the control component is electrically connected to the control end of the driving component 5, and the control component controls the mobile diverter 3 to be in the first state or the second state.

[0040] The driving assembly 5 includes: a micro-driving motor 53, a driving gear 52 and a guide shaft 51. The guide shaft 51 is vertically fixedly connected to the axial side of the fixed diverter 2. A guide hole adapted to the guide shaft 51 is provided on the mobile diverter 3. The circumferential side of the mobile diverter 3 is provided with a helical tooth pattern adapted to the driving gear 52. The micro-driving motor 53 is arranged in the main fluid 1, and its torque output shaft is connected to the driving gear 52, and drives the mobile diverter 3 to rotate.

[0041] 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 is meshed with the helical teeth arranged on the mobile diverter 3. The helical teeth enable the mobile diverter 3 to have an axial moving force when rotating, thereby ensuring that the mobile diverter 3 moves along a predetermined axial path.

[0042] There are at least one micro drive motor 53 and one drive gear 52. The guide hole of the mobile diverter 3 coincides with the central axis of the mobile diverter 3, and the guide shaft 51 coincides with the central axis of the fixed diverter 2, ensuring that no offset or error occurs during the movement.

[0043] The control component controls the driving component 5 through electrical connection, and its main function is to control the mobile diverter 3 to be in the first state or the second state as required. The control component can accurately control the mobile diverter 3 to fit or separate from the fixed diverter 2 in the axial direction by starting, stopping and reversing the motor.

[0044] When the control component issues an instruction (the control button can be set on the outer shell of the main fluid 1), the micro drive motor 53 starts, and drives the mobile diverter 3 to rotate through the driving gear 52, and the mobile diverter 3 moves axially along the guide shaft 51. According to the control instruction (the specific rotation time and rotation angle can be set in advance), the mobile diverter 3 can be driven to the first state (fitting with the fixed diverter 2, part of the flow channel holes are blocked, and a small flow rate is achieved) or the second state (separated from the fixed diverter 2, the fluid passes through all the flow channel holes and the gap between the mobile diverter 3 and the main channel 11, and a large flow rate is achieved).

[0045] Embodiment 3

[0046] This embodiment provides another possible structure of the driving assembly 5 .

[0047] The adjustable diverter also includes a driving component 5 and a control component. The driving component 5 is arranged in the main fluid 1, and the driving end of the driving component 5 is connected to the mobile diverter 3, and drives the mobile diverter 3 to move axially. The control end of the control component is electrically connected to the control end of the driving component 5, and the control component controls the mobile diverter 3 to be in the first state or the second state.

[0048] The driving assembly 5 includes: a linear motor and a guide shaft 51, the guide shaft 51 is vertically fixedly connected to the axial side of the fixed diverter 2, and a guide hole adapted to the guide shaft 51 is provided on the mobile diverter 3. The linear motor is arranged in the main fluid 1, and the moving end of the linear motor is fixedly connected to the mobile diverter 3 and drives the mobile diverter 3 to move axially.

[0049] Different from the traditional rotary motor drive, the linear motor directly generates linear motion, and its moving end is fixedly connected to the mobile diverter 3, driving the mobile diverter 3 to move smoothly along the axial direction. This linear motion mode can reduce the complex gear transmission structure, simplify the mechanical design of the device, and improve the movement accuracy and control response speed.

[0050] The control component realizes real-time control of the driving component 5 through electrical connection. The control component controls the start and stop and the moving direction of the linear motor through electrical signals, thereby controlling the mobile diverter 3 to be in the first state or the second state.

[0051] In addition, the linear motor may also be replaced by a transmission structure capable of linear motion, such as an electric telescopic rod, a threaded screw structure, or the like.

[0052] Embodiment 4

[0053] In this embodiment, the introduction of the two-stage mobile diverter further enhances the flow regulation capability of the diverter system, and achieves more precise flow control through a multi-stage structural design.

[0054] The adjustable flow divider also includes: a secondary movable flow divider, which is movably arranged in the main flow channel 11, and a gap is arranged between the circumferential side surface of the secondary movable flow divider and the inner side surface of the main flow channel 11, and the secondary movable flow divider has two position states: In the first state, the axial side of the secondary mobile flow divider is in contact with the other axial side of the mobile flow divider 3; when the secondary mobile flow divider is in contact with the axial side of the mobile flow divider 3, the fluid can only pass through the secondary mobile flow channel hole, while the other flow channel holes of the mobile flow divider 3 are partially or completely blocked. Since the number of the secondary mobile flow channel holes is small, the fluid flow rate is further reduced, achieving a smaller flow output.

[0055] When in the second state, the axial side of the secondary mobile diverter does not fit into the other axial side of the mobile diverter 3; when the secondary mobile diverter is separated from the mobile diverter 3, more flow channel holes, including the flow channel holes of the mobile diverter 3, are opened, and the first state of the mobile diverter 3 in Example 1 can be executed.

[0056] Secondary mobile flow channel holes are arranged in the secondary mobile flow divider, and the number of the mobile flow channel holes is greater than the number of the secondary mobile flow channel holes.

[0057] The central axis of the mobile flow channel hole is parallel to or coincides with the central axis of the secondary mobile flow channel hole, the central axis of the mobile diverter 3 is coincident with the central axis of the secondary mobile diverter, and the secondary mobile diverter moves axially relative to the mobile diverter 3.

[0058] This embodiment introduces a two-stage mobile diverter to form a multi-stage flow channel adjustment mechanism, which can further refine the flow adjustment range. Under the cooperation of the two-stage diverter, the flow adjustment of the fluid can not only achieve a large degree of control, but also achieve a more precise adjustment effect.

[0059] Similarly, after the introduction of the secondary mobile diverter, a corresponding secondary drive component needs to be configured. The secondary drive component is arranged in the main fluid 1, and the drive end of the secondary drive component is connected to the mobile diverter 3, and drives the secondary mobile diverter 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 mobile diverter to be in the first state or the second state.

[0060] The selection of the secondary drive assembly can refer to the second and third embodiments.

[0061] Embodiment 5

[0062] In order to achieve more refined and wide-range flow regulation, n-level mobile diverters are set, n>2, and the number of flow channel holes in each level of diverters is gradually reduced, so that the fluid flow can be accurately adjusted within a smaller increment range. This multi-level diverter design enables the system to gradually reduce the flow volume of the fluid under different conditions, providing continuous regulation capabilities from large flow to extremely small flow.

[0063] The specific structure of the n-stage mobile diverter can be set with reference to the structure of the two-stage mobile diverter.

[0064] The n-stage mobile flow divider is movably arranged in the main channel 11, and a gap is arranged between the circumferential side surface of the n-stage mobile flow divider and the inner side surface of the main channel 11. The n-stage mobile flow divider has two position states: When in the first state, the axial side surface of the n-stage mobile diverter is in contact with another axial side surface of the n-1-stage mobile diverter; When in the second state, the axial side surface of the n-stage mobile diverter does not fit with the other axial side surface of the n-1-stage mobile diverter; The n-stage mobile flow divider is provided with n-stage mobile flow channel holes, and the number of the n-1-stage flow channel holes is greater than the number of the n-stage mobile flow channel holes.
