Technical Field

[0001] The invention relates to the technical field of fluid conveying pipe equipment, and in particular to a programmable high-frequency throttling regulating device. Background Art

[0002] The throttling device is a flow control device arranged in a pipe full of fluid. The flow beam will form a local contraction at the throttling point, thereby increasing the flow velocity and reducing the static pressure, thus generating a static pressure difference before and after the throttling mechanism. This enables the measurement, control and regulation of fluid flow.

[0003] The existing throttling regulating device controls the local area in the pipeline to reduce the internal space of the pipeline, usually by manual adjustment or solenoid valve control. This adjustment method cannot achieve high-frequency or variable-frequency throttling adjustment on the one hand, and on the other hand, the accuracy of quantitative adjustment is poor.

[0010] Furthermore, the throttling mechanism is composed of a plurality of throttling plates alternately arranged vertically along the axial direction of the mainstream pipeline. The plurality of throttling plates are rigidly connected to the inner wall of the mainstream pipeline, and the pitch thereof can be dynamically adjusted according to the actual flow range.

[0011] Furthermore, in the flow direction of the fluid, adjacent throttle plates are arranged equidistantly, and the azimuth angles of adjacent throttle plates in the flow direction are α∈(0°-360°).

[0012] Furthermore, a positioning bracket may be additionally provided at the connection between the main flow pipeline and the branch flow pipeline, so as to arrange a throttle plate at the position of the main flow pipeline at that location.

[0013] Furthermore, the vertical cross-sections of some of the throttle plates are fan-shaped, and the central angle θ∈(0°-360°) of the fan.

[0014] Furthermore, the outer surfaces of some of the throttle plates are finely processed to reduce throttling resistance.

[0015] Furthermore, each throttle plate is provided with a plurality of through holes in the radial direction, and all of the through holes are rigidly connected to the inner wall surface of the mainstream pipe via positioning screws.

[0016] Furthermore, the driving mechanism is composed of a driving rod, a connecting shaft, a driving motor and a sealing mechanism, wherein:

[0017] One end of the connecting shaft is rollingly connected to the driving motor and passes through the center of the sealing mechanism;

[0018] The driving rod is rigidly connected to the connecting shaft at one side close to the driving motor, and passes through the inner circular spaces of the plurality of throttle plates;

[0019] The driving motor controls the rigid combination of the connecting shaft and the driving rod to perform constant frequency or variable frequency reciprocating linear motion along the central axis of the mainstream pipeline through programming, and realizes precise throttling adjustment by controlling the insertion depth of the driving rod in the throttling mechanism;

[0020] The sealing mechanism is arranged on a side of the main flow pipeline close to the driving motor, and is used to physically isolate the main flow pipeline from the outside.

[0021] Furthermore, the inner wall of the main flow pipe is finely processed to reduce the flow resistance of the fluid.

[0044] like Figure 1 As shown, this embodiment discloses a programmable high-frequency throttling regulating device, including a throttling mechanism, a driving mechanism, and a matching pipeline, wherein:

[0045] The throttling mechanism is movably arranged in a pipeline filled with fluid;

[0046] The driving mechanism is disposed outside the pipeline and connected to the throttling mechanism in the pipeline, and is used to control the frequency of the reciprocating linear motion of the throttling mechanism.

[0047] Furthermore, the pipeline includes a main pipeline 1 and a branch pipeline 2, and the main pipeline 1 and the branch pipeline 2 are vertically connected. In this embodiment, the inner wall of the main pipeline 1 is finely processed to reduce the flow resistance of the fluid.

[0048] Furthermore, the throttling mechanism is composed of a plurality of throttling plates 3 alternately arranged vertically along the axial direction of the mainstream pipeline 1, and the plurality of throttling plates 3 are rigidly connected to the inner wall of the mainstream pipeline 1, and the pitch 4 thereof can be dynamically adjusted according to the actual flow range. In this embodiment, a plurality of throttling plates 3 are arranged on the throttling mechanism, and the number of throttling plates 3 located in the fluid region determines the throttling effect, and the throttling adjustment is completed by adjusting the number of throttling plates 3 in the flow channel.

[0049] In the flow direction of the fluid, the adjacent throttle plates 3 are arranged equidistantly or unequally. The azimuth angle α∈(0°-360°) of the adjacent throttle plates 3 in the flow direction is preferably 30°.

[0050] Figure 1 In the embodiment, a positioning bracket 5 can be additionally provided at the connection between the main flow pipeline 1 and the branch flow pipeline 2, so as to arrange the throttle plate 3 at the position of the main flow pipeline 1 at that location.

[0051] Furthermore, the vertical cross-sections of the throttle plates 3 are fan-shaped structures, and the central angle θ∈(0°-360°) of the fan-shaped structure. Optionally, the fan-shaped surface can be a hollow design or a solid design.

[0052] The fan-shaped side of the throttle plate is as follows Figure 3 As shown, the centers of the side sectors of the plurality of throttle plates 3 coincide with the central axis of the main flow pipe 1, and the center angle θ is 150°.

[0053] In this embodiment, the outer surfaces of some of the throttle plates 3 are finely processed to reduce the throttling resistance.

[0054] Figure 2 This is a cross-sectional view of the throttling mechanism along the line AA. Each throttling plate 3 is provided with a plurality of through holes 6 in the radial direction, and all of them are rigidly connected to the inner wall of the mainstream pipe 1 via positioning screws 7 .

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

[0056] Furthermore, 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;

[0058] The driving rod 8 is rigidly connected to the connecting shaft 9 at a side close to the driving motor 10, and passes through the inner circular spaces of the throttle plates 3;

[0059] The driving motor 10 controls the rigid combination of the connecting shaft 9 and the driving rod 8 to perform reciprocating linear motion at a constant frequency or variable frequency along the central axis of the mainstream pipeline 1 through programming, and realizes precise throttling adjustment by controlling the insertion depth of the driving rod 8 in the throttling mechanism;

[0060] The sealing mechanism 11 is disposed on a side of the main flow pipeline 1 close to the driving motor 10 , and is used to physically isolate the main flow pipeline 1 from the outside.

[0061] Figure 4It is a flow regulation curve diagram. When the driving rod 8 is fully inserted into the throttling mechanism, the resistance of the mainstream pipeline 1 is the largest and the flow is the smallest; when the driving rod 8 is fully pulled out of the throttling mechanism, the resistance of the mainstream pipeline 1 is the smallest and the flow is the largest.

[0062] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
