[0044] As shown in the Figure 1 The embodiment discloses a programmable high-frequency throttling regulating device, comprising a throttling mechanism, a driving mechanism, and a matched pipeline, wherein:

[0045] The throttling mechanism is movably arranged in the pipeline full of fluid;

[0046] The driving mechanism is externally arranged outside the pipeline and connected with the throttling mechanism in the pipeline, and is used for controlling the frequency of reciprocating linear motion of the throttling mechanism.

[0047] Further, the pipeline comprises a main flow pipeline 1 and a branch flow pipeline 2, and the main flow pipeline 1 and the branch flow pipeline 2 are vertically communicated. In the embodiment, the inner wall of the main flow pipeline 1 is finely processed, for reducing the flow resistance of fluid.

[0048] Further, the throttling mechanism is composed of a plurality of throttling plates 3 alternately arranged up and down along the axis of the main flow pipeline 1, and the plurality of throttling plates 3 are rigidly connected with the inner wall surface of the main flow pipeline 1, and the pitch 4 can be dynamically adjusted according to the actual flow range. In the embodiment, a plurality of throttling plates 3 are arranged on the throttling mechanism, and the number of the throttling plates 3 located in the fluid region determines the throttling effect, and the adjustment of the number of the throttling plates 3 in the flow channel is used to complete the throttling adjustment.

[0049] In the flow direction of fluid, the adjacent throttling plates 3 are arranged at equal intervals, or can be arranged at unequal intervals. The azimuth angle α of the adjacent throttling plates 3 in the flow direction is ∈(0°-360°). Preferably, the azimuth angle α of the adjacent throttling plates 3 in the flow direction is 30°.

[0050] Figure 1 In particular, the connecting part of the main flow pipe 1 and the branch flow pipe 2 can be additionally provided with a positioning support 5 for arranging the throttle plate 3.

[0051] Further, the vertical section of the throttle plate 3 is in a fan-shaped structure, and the central angle of the fan is θ∈(0°-360°).

[0052] The fan-shaped side of the throttle plate is shown in FIG. 3, and the central angle of the fan is θ=150°. Figure 3

[0053] In this embodiment, the outer surface of the throttle plate 3 is finely processed to reduce the throttling resistance.

[0054] Figure 2 The throttle mechanism A-A is shown in FIG. 4, and the radial direction of each throttle plate 3 is provided with a plurality of through holes 6, which are rigidly connected to the inner wall of the main flow pipe 1 by positioning screws 7.

[0055] In this embodiment, the throttle mechanism is inserted into the main flow pipe 1 and adheres to the inner wall of the main flow pipe 1. When the fluid enters the throttle mechanism, it successively passes through the fan-shaped throttle plates arranged alternately. The fluid will shrink at the throttling part and flow back and forth, forming a local flow resistance and increasing the static pressure difference before and after.

[0056] Further, the driving mechanism is composed of a driving rod 8, a connecting shaft 9, a driving motor 10 and a sealing mechanism 11, wherein:

[0057] One end of the connecting shaft 9 is rollingly connected to the driving motor 10 and passes through the center of the sealing mechanism 11;

[0060] The sealing mechanism 11 is arranged on the side of the main flow pipe 1 close to the driving motor 10, which is used to isolate the main flow pipe 1 from the outside physically.

[0061] Figure 4 ​For the flow regulation curve, when the driving rod 8 is fully inserted into the throttle mechanism, the main flow pipeline 1 has the maximum resistance and the minimum flow; when the driving rod 8 is fully extracted from the throttle mechanism, the main flow pipeline 1 has the minimum resistance and the maximum flow.

[0062] The above merely provides the preferred embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
