[0030] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] See also Figure 1 As shown, one embodiment of the present application discloses a valve body structure installed between pipelines for adjusting the flow rate of the fluid in the pipeline. The valve body structure includes a valve body 100, a blade assembly and a drive assembly 300.

[0032] Specifically, the valve body 100 has a fluid channel; the blade assembly includes a blade seat 210, a diverter plate 220 and a center bracket 230, and there are multiple blade seats 210. The multiple blade seats 210 are arranged in sequence along the circumference of the inner wall of the fluid channel. The number of diverter plates 220 corresponds to the blade seat 210, and each blade seat 210 is correspondingly installed with a diverter plate 220. The center bracket 230 is arranged in the fluid channel, and each diverter plate 220 is connected to the center bracket 230; and the drive assembly 300 drives the blade seat 210 to rotate around its own rotation axis to drive the diverter plate 220 to rotate.

[0033] In the valve body structure provided in the embodiment of the present application, the drive assembly 300 can drive the blade seat 210 to rotate about its own rotation axis, thereby driving the diverter plates 220 mounted on the blade seat 210 to rotate. When the diverter plates 220 rotate, the opening and closing angles of each diverter plate 220 can be changed, thereby achieving the purpose of adjusting the flow rate of the pipeline fluid.

[0034] In an embodiment of the present application, flow regulation is related to the opening and closing angle of the diverter plate 220, wherein there are multiple diverter plates 220, and the opening and closing angle of each diverter plate 220 can be controlled by the rotation angle of each blade seat 210. In this way, the flexibility of the opening and closing of the valve body structure can be improved, which is also conducive to improving the accuracy of flow regulation.

[0035] In some embodiments of this application, see Figures 1 to 3 The drive assembly 300 includes a drive mechanism. Each blade seat 210 is connected to a transmission structure, which is a first rotating gear. The first rotating gears corresponding to two adjacent blade seats 210 are meshed with each other. The drive mechanism drives one of the first rotating gears to rotate, thereby driving each blade seat 210 to rotate. In other words, the same first rotating gear is meshed with the first rotating gears located on both sides of it. When one of the first rotating gears rotates, it can drive the rotation of the two adjacent first rotating gears. Therefore, by using the drive mechanism to drive one of the first rotating gears, all blade seats 210 can be driven to rotate.

[0036] in, Figure 4 A schematic diagram of the rotation direction of multiple blade seats 210 in this embodiment is shown. In the figure, the direction indicated by the arrow represents the rotation direction of the blade seat 210.

[0037] In the above embodiment, the movement of each blade seat 210 is transmitted by the mutual engagement of each first rotating gear, which can simplify the transmission structure, increase the stability of the movement, and help reduce the failure rate.

[0038] It is worth understanding that by controlling the rotation angle of the blade seat 210, the opening and closing angle of the valve body structure can be controlled; by controlling the forward rotation or flipping of the blade seat 210 by the driving mechanism, the opening and closing control of the valve body structure can be achieved.

[0039] In the actual assembly process, in order to improve assembly efficiency, the valve body structure can be assembled in a fully closed state or a fully open state.

[0040] For example, see Figure 2When the valve body structure is in a fully closed state, the diverter pieces 220 are spliced ​​into a complete sealing structure to block the fluid channel. At this time, the diverter pieces 220 are arranged horizontally. In this state, it is convenient to position the diverter pieces 220 and the blade seats 210, which is conducive to improving assembly efficiency.

[0041] In some other embodiments of the present application, the drive assembly 300 includes a drive mechanism and a transmission structure. The transmission structure includes a first transmission member and a second rotating gear. Each blade seat 210 is connected to a corresponding second rotating gear. The first transmission member is a circular gear ring. The second rotating gear connected to each blade seat 210 is meshed with the gear ring. The drive mechanism drives the first transmission member to rotate, thereby driving each blade seat 210 to rotate. The gear ring has a meshing portion on the side close to the second rotating gear that meshes with the second rotating gear.

[0042] In some embodiments of this application, see Figure 1 and Figure 5 The valve body 100 includes a mounting groove 110 circumferentially arranged along the inner wall of the fluid channel, with a vane seat 210 disposed within the mounting groove 110. The mounting groove 110 is recessed relative to the peripheral wall of the fluid channel, and the vane seat 210 is at least partially disposed within the mounting groove 110, thereby reducing the mounting groove's impact on fluid flow within the fluid channel. Furthermore, with the vane seat 210 disposed within the mounting groove 110, the opening and closing angles of the fluid channel are controlled as much as possible by the opening and closing angles of the various diverter blades 220, thereby minimizing fluid flow through the gaps between adjacent vane seats 210 and improving flow regulation accuracy.

[0043] In some embodiments of this application, see Figure 5 The vane assembly includes a bearing 240 mounted on the valve body 100, with the vane seat 210 matingly connected to the bearing 240. This reduces the rotational resistance of the vane seat 210 and improves the stability of its movement. Furthermore, the connection between the vane seat 210 and the bearing 240 enhances the consistency and smoothness of rotation, which also helps improve the accuracy of flow regulation.

[0044] In some embodiments of the present application, the valve body 100 has a housing cavity that is separated from the fluid passage, and the transmission mechanism is disposed within the housing cavity. That is, in this embodiment, the blade seat 210 that drives the diverter plate 220 is located within the fluid passage of the valve body 100, but the other transmission mechanisms that drive the blade seat 210 are disposed within the housing cavity of the valve body 100. This optimizes the sealing performance of the valve body structure, making it suitable for use in scenarios with strict sealing requirements.

[0045] In a possible implementation, the blade seat 210 is sealed to the valve body 100 to further improve the sealing performance of the valve body structure.

[0046] In some embodiments of this application, see Figures 1 to 3 The central support 230 includes a support body 231 and a clamping mechanism 232. The clamping mechanism 232 is rotatably connected to the support body 231. Each diverter 220 is connected to a different clamping mechanism 232. In this way, each diverter 220 can rotate relative to the support body 231.

[0047] In one possible implementation, see Figures 1 to 3 The central support 230 is suspended in the fluid passage of the valve body 100. Specifically, the central support 230 includes a support body 231 and multiple clamping mechanisms 232. The multiple clamping mechanisms 232 are spaced apart around the periphery of the support body 231, and each clamping mechanism 232 is fixedly connected to a corresponding diverter plate 220. In this way, each diverter plate 220 can support the central support 230.

[0048] Furthermore, in terms of material selection, the center bracket 230 should be made of lightweight materials as much as possible. For example, the center bracket 230 can be made of aluminum metal or aluminum alloy material to reduce the weight of the center bracket 230.

[0049] Furthermore, in order to reduce the overall weight of the central support 230 , the central support 230 may be designed to reduce weight in terms of shape, structure, etc., so as to further optimize the weight of the central support 230 .

[0050] In some embodiments of the present application, the clamping mechanism 232 includes a first portion and a second portion spaced apart, with the diverter 220 disposed between the first portion and the second portion. The diverter 220 can be secured by the clamping action of the first portion and the second portion, or by the fastening action of the first portion, the second portion, and other fasteners, without limitation herein.

[0051] In one possible embodiment, the cross-sectional area of ​​the first part and / or the second part is smaller than the area of ​​the diverter plate 220 on the side close to the center support 230. In this way, the volume of the first part and / or the second part can be reduced, which is conducive to further reducing the weight.

[0052] In other embodiments of the present application, the central support 230 includes a support body 231 and a frame. One end of the frame is rotatably connected to the support body 231, and the other end is fixedly connected to the blade seat 210. The frame is also fixedly connected to the diverter plate 220, and the extension direction of the frame is consistent with the radial direction of the support body 231. This can increase the support strength of the central support 230 on the diverter plate 220 and reduce the deformation of the diverter plate 220 under fluid pressure.

[0053] In some embodiments of this application, see Figures 1 to 3 The flow divider 220 is V-shaped. By rotating the blade seat 210, the gap between two adjacent flow dividers 220 can be changed, thereby changing the flow rate to achieve the purpose of flow regulation.

[0054] In some embodiments of the present application, the driving mechanism includes a motor.

[0055] In some other embodiments, when the environment is suitable, the driving mechanism may also use a manual wheel to control the rotation of the diverter plate 220.

[0056] In the embodiment of the present application, the number of diverter plates 220 within the valve body 100 can be varied based on the diameter of the fluid passageway of the valve body 100. The widest position of a single diverter plate 220 affects the height of the valve body 100. Conversely, if the height of the valve body 100 is desired to be reduced, the width of a single diverter plate 220 can be reduced. It should be understood that, in the foregoing description, the height of the valve body 100 refers to the length of the valve body 100 along the direction in which the fluid passageway extends.

[0057] Another embodiment of the present application discloses a pipeline delivery system including the aforementioned valve structure, which has all the technical benefits of the aforementioned valve structure. For example, the pipeline delivery system of this embodiment can improve the accuracy of flow control, enhance integration, simplify the drive structure, and increase operational stability. The opening and closing of the valve structure is flexible and controllable, making it suitable for a variety of applications to the greatest extent possible.
