Description

Technical Field

[0001] This utility model belongs to the field of regulating valve technology, specifically relating to a regulating valve for a dust removal device. Background Technology

[0002] In existing dust removal systems, adjusting airflow and dust extraction efficiency typically relies on traditional cover-type butterfly valves. For example, a smart regulating electric butterfly valve, as described in patent CN202323510522.X, mainly comprises a valve body with a hollow flow channel and a butterfly plate (circular or elliptical) rotatably mounted inside the valve body. When the butterfly plate rotates to a position parallel to the fluid flow direction, the valve is open, allowing fluid to flow freely; when the butterfly plate rotates to a position perpendicular to the fluid flow direction, the valve is closed, preventing fluid flow. Operators can then control the fluid flow rate by rotating the butterfly plate to different angles. However, in practical applications, the following problems still exist:

[0003] 1. The fluid may carry fibrous materials such as cloth strips. These materials may get stuck between the butterfly plate and the valve seat when passing through the valve, causing the cloth strips to hang, thus affecting the normal operation of the valve.

[0004] 2. The rotation of the butterfly plate may not be completely aligned with the direction of fluid flow, resulting in uneven distribution of airflow when passing through the valve. This leads to uneven distribution of the scouring effect and pressure impact on the butterfly plate, which can easily cause uneven wear between the butterfly plate and the valve seat.

[0005] 3. Due to differences in the number of branches and pipe diameters, the internal pressure of the system may become unbalanced, affecting dust removal efficiency and system stability.

[0006] Based on this background, a regulating valve for a dust removal device is designed. The regulating valve is shaped like a hollow sphere. The first regulating plate and the second regulating plate are both arc-shaped to adapt to the shape of the shell, in order to overcome the above-mentioned defects. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example 1

[0038] like Figures 1 to 9The regulating valve shown is for a dust removal device and includes a first flange 2 and a second flange 3 symmetrically arranged. A housing 1 is connected between the first flange 2 and the second flange 3. A first vent 201 is opened on the first flange 2, and a second vent 301 is opened on the second flange 3. A first rotating shaft 51 is rotatably mounted on the front side of the housing 1, and a second rotating shaft 61 is rotatably mounted on the rear side of the housing 1. A first adjusting plate 52 and a second adjusting plate 62 are connected between the first rotating shaft 51 and the second rotating shaft 61. The first adjusting plate 52 has two arc-shaped... The second adjusting plate 62 has two angle plates. A first adjusting member 54 is provided on the first rotating shaft 51 at the front side of the housing 1, and a second adjusting member 64 is provided on the second rotating shaft 61 at the outside side of the housing 1. The arc-shaped plate is divided into a first arc-shaped plate 531 and a second arc-shaped plate 532. The first arc-shaped plate 531 is fixedly connected to the first rotating shaft 51, and the second arc-shaped plate 532 is rotatably connected to the second rotating shaft 61. The angle plates are divided into a first angle plate 631 and a second angle plate 632. The first angle plate 631 is fixedly connected to the first rotating shaft 51. The first rotating shaft 51 is rotatably connected, and the second angle plate 632 is fixedly connected to the second rotating shaft 61; the first rotating shaft 51 is provided with a first sector-shaped adjusting plate 541, the top of the first sector-shaped adjusting plate 541 is provided with a first handle 542, and the centrifugal edge of the first sector-shaped adjusting plate 541 is provided with a first arc-shaped groove 543; the front side of the housing 1 is provided with a first guide rod 7, the first guide rod 7 is located in the first arc-shaped groove 543, and a first limiting block 701 is threaded on the first guide rod 7 at the position on the front side of the first arc-shaped groove 543; the first rotating shaft The first adjusting plate 52 and the second adjusting plate 641 are provided with a second sector-shaped adjusting plate 641. The bottom of the second sector-shaped adjusting plate 641 is provided with a second handle 642. The centrifugal edge of the second sector-shaped adjusting plate 641 is provided with a second arc-shaped groove 643. The rear side of the housing 1 is provided with a second guide rod 8. The second guide rod 8 is located in the second arc-shaped groove 643. The second guide rod 8 is threaded with a second limiting block 801 at the position on the rear side of the second arc-shaped groove 643. The housing 1 is spherical. The first adjusting plate 52 and the second adjusting plate 62 are both arc-shaped in accordance with the shape of the housing 1.

[0039] In this invention, the housing 1 is generally spherical with a hollow interior. The first adjusting plate 52 and the second adjusting plate 62 are both arc-shaped to fit the shape of the housing 1. This design prevents debris carried by the airflow from being easily caught, especially in the closed state, where debris automatically falls off, avoiding the problem of fibrous debris clogging the regulating valve and affecting its normal operation. The rounded appearance of the first adjusting plate 52 and the second adjusting plate 62 ensures even airflow distribution, preventing airflow from being misaligned, thus reducing uneven erosion and pressure impact on the adjusting plates, extending the valve's service life and sealing performance. The novel design achieves synchronized rotation of the first adjusting plate 52 and the second adjusting plate 62 at the same angle through the synchronous adjustment of the first rotating shaft 51 and the second rotating shaft 61. This not only ensures precise control of the fluid channel size but also ensures concentrated fluid flow, improving dust removal efficiency. The design also includes a first adjusting component 54 and a second adjusting component 64, comprising a first sector-shaped adjusting plate 541, a second sector-shaped adjusting plate 641, a first handle 542, and a second handle 642. This allows operators to easily adjust the rotation of the first adjusting plate 52 and the second adjusting plate 62 from outside the regulating valve. Furthermore, a guide structure and a limiting block are provided to ensure the accuracy and stability of the adjustment.

[0040] Example 2

[0041] like Figures 1 to 9 The control valve shown is for a dust removal device and includes a first flange 2 and a second flange 3 symmetrically arranged. In practical applications, the control valve in this embodiment is mostly installed in vertical pipes, where the first flange 2 and the second flange 3 are vertically symmetrical. When the control valve is installed in a horizontal pipe, they are horizontally symmetrical. For ease of understanding, this embodiment temporarily sets the first flange 2 and the second flange 3 as horizontally symmetrical, and a housing 1 is connected between the first flange 2 and the second flange 3. The housing 1, including its internal structure, constitutes the control valve. Furthermore, both the first flange 2 and the second flange 3 have multiple mounting holes 4 for mounting on pipes or other connecting platforms. In actual installation, nuts or nuts + washers can be selected to ensure the sealing of the flow channel.

[0042] It should be noted that the specific structure of the commonly used cover-type butterfly valve can be referenced in a smart regulating electric butterfly valve with patent number CN202323510522.X. The butterfly valve mainly includes a valve body with a hollow flow channel and a butterfly plate (circular or elliptical) rotatably installed inside the valve body. When the butterfly plate rotates to a position parallel to the fluid flow direction, the valve is in the open state, and the fluid can pass freely. When the butterfly plate rotates to a position perpendicular to the fluid flow direction, the valve is in the closed state, and the fluid flow is blocked. In addition, the operator can control the flow rate of the fluid by controlling the butterfly plate to rotate to different angles.

[0043] However, in practical applications, the fluid may carry fibrous materials such as cloth strips. These materials may get stuck between the disc and the valve seat when passing through the valve, causing the cloth strips to hang, which affects the normal operation of the valve. In addition, the rotation of the disc may not be completely aligned with the direction of fluid flow, which can easily lead to uneven distribution of airflow when passing through the valve. Consequently, the scouring effect and pressure impact of the fluid on the disc will be unevenly distributed, which can easily lead to uneven wear between the disc and the valve seat, thereby reducing the valve's sealing performance and affecting its final service life and regulation accuracy.

[0044] Based on the above background, in this embodiment, the housing 1 is shaped as a hollow sphere. A first flange 2 and a second flange 3 are installed on its left and right sides through a first vent 201 and a second vent 301, respectively. The flanges and vents are in communication, meaning the regulating valve is shaped like a sphere connected to a cylindrical body. A first adjusting plate 52 and a second adjusting plate 62 are rotatably mounted inside the housing 1, both being arc-shaped to fit the shape of the housing 1. Both the first adjusting plate 52 and the second adjusting plate 62 are in contact with the inner wall of the housing 1. By adjusting the rotation of the first adjusting plate 52 and the second adjusting plate 62, the flow rate of the fluid is controlled. The combined area of ​​the first adjusting plate 52 and the second adjusting plate 62 is larger than the area of ​​the first vent 201. When the first adjusting plate 52 and the second adjusting plate 62 rotate to contact each other, it indicates that the combined first adjusting plate 52 and the second adjusting plate 62 block the first vent 201, causing the entire regulating valve to be in a closed state. Thus, based on the rounded appearance design of the first regulating plate 52 and the second regulating plate 62, the debris carried by the airflow will not be easily caught; and in practical applications, when the regulating valve is in a vertical state, the combination of the first regulating plate 52 and the second regulating plate 62 will block the first vent 201 of the first flange 2, and the debris will fall off automatically, thereby avoiding the problem of fibrous debris clogging the regulating valve and affecting the normal use of the subsequent regulating valve.

[0045] A first rotating shaft 51 is rotatably provided on the front side of the housing 1, and a second rotating shaft 61 is rotatably provided on the rear side of the housing 1. The first rotating shaft 51 and the second rotating shaft 61 are on the same horizontal line. The first adjusting plate 52 and the second adjusting plate 62 are connected between the first rotating shaft 51 and the second rotating shaft 61. It can be understood that the first adjusting plate 52 located above has two arc-shaped plates at the front and back, and the second adjusting plate 62 located below has two angled plates at the front and back. The arc-shaped plates are all located outside the angled plates. In this way, the first adjusting plate 52 and the second adjusting plate 62 can rotate without affecting each other.

[0046] Furthermore, the arc-shaped plate is divided into a first arc-shaped plate 531 and a second arc-shaped plate 532. The first arc-shaped plate 531, located on the front side, is fixedly connected to the first rotating shaft 51, while the second arc-shaped plate 532 is rotatably connected to the second rotating shaft 61. Similarly, the angled plate is divided into a first angled plate 631 and a second angled plate 632. The first angled plate 631, located on the front side, is rotatably connected to the first rotating shaft 51, while the second angled plate 632 is fixedly connected to the second rotating shaft 61. In simple terms, the rotation of the first rotating shaft 51 can drive the first adjusting plate 52 to rotate within the housing 1 via the first arc-shaped plate 531. At this time, the second arc-shaped plate 532 rotates on the second rotating shaft 61, which provides support. Conversely, the rotation of the second rotating shaft 61 can drive the second adjusting plate 62 to rotate within the housing 1 via the second angled plate 632. At this time, the first angled plate 631 rotates on the first rotating shaft 51, which provides support.

[0047] In summary, taking the connection center line between the first rotating shaft 51 and the second rotating shaft 61 as a reference, the first adjusting plate 52 and the second adjusting plate 62 are in a vertically symmetrical state within the housing 1, such as... Figure 1-5 As shown, this is the maximum flow state of the regulating valve, and as... Figure 7-9 As shown, the first adjusting plate 52 and the second adjusting plate 62 both rotate toward the first vent 201 until they come into contact with each other and complete the combination, blocking the first vent 201 and the regulating valve is in a closed state; then, the operator can adjust the rotation amplitude of the first adjusting plate 52 and the second adjusting plate 62 in the housing 1 to control the size of the fluid channel formed by the two, and finally realize the flow control of the fluid.

[0048] Furthermore, a first adjusting member 54 is provided on the first rotating shaft 51 at the front side of the housing 1, and a second adjusting member 64 is provided on the second rotating shaft 61 at the rear side of the housing 1, for the operator to adjust the rotation of the first adjusting plate 52 and the second adjusting plate 62 from the outside of the regulating valve. Specifically:

[0049] The first rotating shaft 51 is provided with a first sector-shaped adjusting plate 541, and the top of the first sector-shaped adjusting plate 541 is provided with a first handle 542. Pushing the first handle 542 can drive the first sector-shaped adjusting plate 541 and the first rotating shaft 51 to rotate, thereby adjusting the rotation of the first adjusting plate 52. The second rotating shaft 61 is provided with a second sector-shaped adjusting plate 641, and the bottom of the second sector-shaped adjusting plate 641 is provided with a second handle 642. Pushing the second handle 642 can drive the second sector-shaped adjusting plate 641 and the second rotating shaft 61 to rotate, thereby adjusting the rotation of the second adjusting plate 62.

[0050] Example 3

[0051] like Figures 1 to 9The regulating valve shown is used in a dust removal device. By pushing the first handle 542, the first sector-shaped regulating plate 541 and the first rotating shaft 51 are rotated, thereby adjusting the rotation of the first regulating plate 52. By pushing the second handle 642, the second sector-shaped regulating plate 641 and the second rotating shaft 61 are rotated, thereby adjusting the rotation of the second regulating plate 62. In this way, by adjusting the rotation amplitude of the first regulating plate 52 and the second regulating plate 62 within the housing 1, the size of the fluid channel formed by the two can be controlled, ultimately achieving flow control of the fluid.

[0052] To achieve precise and stable adjustment of the first adjusting plate 52 and the second adjusting plate 62, a guide structure is also provided. A first arc-shaped groove 543 is opened at the centrifugal edge of the first sector-shaped adjusting plate 541, and a first guide rod 7 is provided on the front side of the housing 1. The first guide rod 7 is located in the first arc-shaped groove 543. When the regulating valve is at the maximum ventilation volume, the first guide rod 7 is at the lowest point of the first arc-shaped groove 543. A second arc-shaped groove 643 is opened at the centrifugal edge of the second sector-shaped adjusting plate 641, and a second guide rod 8 is provided on the rear side of the housing 1. The second guide rod 8 is located in the second arc-shaped groove 643. When the regulating valve is at the maximum ventilation volume, the second guide rod 8 is at the highest point of the second arc-shaped groove 643.

[0053] The first guide rod 7 and the second guide rod 8 are symmetrically arranged. When the first handle 542 is pushed to rotate the first sector-shaped adjusting plate 541, the first sector-shaped adjusting plate 541 can be rotated stably under the guidance of the first arc-shaped groove 543, so as to accurately adjust the angle of the first adjusting plate 52. A first limiting block 701 is threaded on the first guide rod 7 at the position in front of the first arc-shaped groove 543. It can be understood that after the adjustment of the first sector-shaped adjusting plate 541 is completed, the operator can fix the adjusted first sector-shaped adjusting plate 541 to the housing 1 by rotating the first limiting block 701. Similarly, a second limiting block 801 is threaded on the second guide rod 8 at the position behind the second arc-shaped groove 643. After the operator completes the adjustment of the second sector-shaped adjusting plate 641, the second limiting block 801 is rotated to fix the adjusted second sector-shaped adjusting plate 641 to the housing 1. When it is necessary to adjust again, the first limiting block 701 and the second limiting block 801 are rotated to loosen the first sector-shaped adjusting plate 541 and the second sector-shaped adjusting plate 641. The handle is then pushed to rotate and adjust the corresponding sector-shaped adjusting plate.

[0054] Furthermore, angle values ​​can be engraved on the first sector adjustment plate 541 and the second sector adjustment plate 641 at the position outside the arc groove, for manual monitoring and reference of the adjustment of the internal first adjustment plate 52 and second adjustment plate 62; with the guide rod as the starting point and the arc groove as the trajectory angle, specific and clear numbers are used to guide the staff to adjust to the required fluid channel, thereby improving the accuracy of the adjustment.

[0055] Example 4

[0056] In another feasible embodiment, electrical devices can be used instead of manual adjustment of the first sector adjustment plate 541 and the second sector adjustment plate 641. Such electrical devices include, but are not limited to, motors, telescopic rods, and any other device capable of rotating the sector adjustment plates. For ease of understanding, this embodiment specifically uses a motor as the driving component, divided into a first motor and a second motor. The first motor is connected to the first rotating shaft 51, and the second motor is connected to the second rotating shaft 61. By driving the first motor and the second motor, the first rotating shaft 51 and the second rotating shaft 61 are driven, thereby adjusting the subsequent first adjustment plate 52 and the second adjustment plate 62. The first adjustment plate 52 and the second adjustment plate 62 exhibit the required rotation amplitude in the housing 1, thereby controlling the size of the fluid channel formed by the two and ultimately achieving flow control of the fluid.

[0057] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0058] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
