[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0058] Please refer to the instruction manual Figure 1 To Attachment Figure 5 The present application provides a valve opening adjustment device, which includes a substrate 1, a driving member 2, a first shaft 3 and a second shaft 4. The substrate 1 carries the driving member 2, and the driving member 2 includes a driving shaft 21.

[0059] The substrate 1 is plate-shaped and can be regarded as an installation reference, on which a driving member 2 is provided, which is used to output the power generated by the driving member 2 through the rotation of the driving shaft 21. The driving member 2 can be specifically a driver such as a motor. In some embodiments, the driving member 2 is arranged on the first surface of the substrate 1, and the driving shaft 21 passes through the substrate 1 and is transmission-connected to the first shaft 3 located on the second surface of the substrate 1, that is, the driving member 2 transmits power to the first shaft 3.

[0060] Please refer to the instruction manual Figure 6 To Attachment Figure 8 The first shaft 3 is provided with a sliding chamber 31 along its axial direction, and a groove 311 is provided at the end of the sliding chamber 31 away from the driving shaft 21. A second shaft 4 is provided at the end of the first shaft 3 where the groove 311 is provided. The second shaft 4 is coaxially arranged with the first shaft 3, and an adapting groove 41 is provided inside the end surface of the second shaft 4 on the side where the second shaft 4 is connected to the groove 311. The adapting groove 41 can be connected with the groove 311 to form a through space 5.

[0061] A linkage member 6 is provided in the first shaft 3 and the second shaft 4, and an adapting tooth 61 is provided at the end of the linkage member 6. The adapting tooth 61 can be slidably provided in the through-space 5. Obviously, the adapting groove 41 and the clamping groove 311 are different parts of the through-space 5. If the adapting groove 41 and the clamping groove 311 are set as circular tooth grooves, the through-space 5 is also circular, and the inner wall has a tooth groove, and the tooth groove should match the adapting tooth 61, that is, the adapting tooth 61 can extend into the through-space 5 and mesh with the tooth groove to limit the relative position rotation of the two.

[0062] In this article, based on the coaxial arrangement of the first axis 3 and the second axis 4, the length extension direction of the adapting groove 41 and the clamping groove 311 can be set to extend along the axial direction of the first axis 3, that is, the tooth groove of the through space 5 extends along the axial direction of the first axis 3, and the axial length of the adapting groove 41 is greater than or equal to the length of the adapting tooth 61. When the adapting tooth 61 is fully extended into the adapting groove 41, the adapting tooth 61 is only engaged with the second axis 4, and this position is recorded as the first position. The axial length of the clamping groove 311 is less than the length of the adapting tooth 61, that is, after the adapting tooth 61 is fully engaged with the clamping groove 311, there is still a partial section extending into the adapting groove 41 and engaged with the adapting groove 41, and the adapting tooth 61 fixes the first axis 3 and the second axis 4. The position of the adapting tooth 61 at this time is recorded as the second position.

[0063] An output shaft 7 is drivingly connected to one end of the second shaft 4 away from the adapting groove 41 . One end of the output shaft 7 away from the base plate 1 is connected to the valve body. The second shaft 4 drives the output shaft 7 to rotate to turn the valve to a preset angle.

[0064] The control component 8 is coupled to the driving member 2, and the control component 8 can control the driving member 2 to rotate to a preset angle according to the received control signal. Here, the control component 8 can obtain the control signal sent from the outside in the form of wireless or wired transmission, so as to control the driving member 2 to rotate to a preset angle. Obviously, the control component 8 should include a signal receiving module and a control module. The signal receiving module and the control module are signal-connected, and the control module and the driving member 2 are connected. The signal receiving module is used to receive the control signal transmitted from the outside, and the control module is used to control the operation of the driving member 2, that is, to control the rotation angle of the driving shaft 21.

[0065] In addition, the control component 8 can also perform a preset action when the drive of the driver 2 fails; here, the drive failure of the driver 2 includes a variety of situations. For example, when the driver 2 is powered off, it is obvious that the drive function of the driver 2 fails. The control component 8 and the driver 2 are connected in series, and the control component 8 is connected to the power supply status display circuit. The control component 8 includes a display light. It can be considered that a display light is provided on the power supply status display circuit, and the display light flashes when the power is on; when the driver 2 is powered off due to an external power supply, the control component 8 will also be powered off. At this time, the power supply status display circuit is powered off, and the display light of the control component 8 goes out, thereby reminding the operator to take corresponding measures, such as turning off the power supply and other operations. At this time, the display light of the control component 8 goes out, which can be regarded as the preset action performed by the control component 8 when the drive of the driver 2 fails.

[0066] Of course, the control component 8 may also include alarm devices such as emergency lighting and / or sound and light alarms. The alarm devices are connected to the uninterruptible power supply. When the external power supply of the driving component 2 is cut off, the control component 8 will also be affected by the power outage of the external power supply and lose power. At this time, the uninterruptible power supply starts to supply power, and the emergency lighting and / or sound and light alarms realize emergency lighting and / or sound and light alarms under the power supply of the uninterruptible power supply to remind the operator to take corresponding measures. Obviously, the emergency lighting and / or sound and light alarms here can be regarded as the preset action performed by the control component 8 when the driving of the driving component 2 fails.

[0067] The driving failure situation of the driving member 2 also includes: when the control component 8 controls the driving shaft 21 of the driving member 2 to rotate a preset angle, but the difference between the actual rotation angle of the driving shaft 21 and the preset angle is large, then the driving of the driving member 2 can also be considered to have failed; a Hall sensor can be provided at the driving shaft 21, the control component 8 is connected to the alarm component, the Hall sensor is electrically connected to the control component 8, and the Hall sensor is used to detect the actual rotation angle signal value of the driving shaft 21, and the detected actual rotation angle signal value is fed back to the control component 8, and the control component 8 compares the actual rotation angle with the preset angle. If the difference between the two exceeds the preset difference, the control component 8 determines that the driving of the driving member 2 has failed. At this time, the control component 8 controls the alarm component to issue an alarm, such as an audible and visual alarm, to remind the operator to take corresponding measures. It can be seen that the action of the control component 8 controlling the alarm component to issue an alarm is the preset action performed by the control component 8 when the driving of the driving member 2 fails.

[0068] In addition, the preset actions performed by the control component 8 when the drive of the driving member 2 fails are not limited to the display light turning off and the alarm component alarming as recorded above, but can also actively control the position of the linkage member 6 to disconnect the first shaft 3 and the second shaft 4, that is, disconnect the connection between the driving member 2 and the output shaft 7.

[0069] In combination with the above, when the first shaft 3 and the second shaft 4 are transmission-connected, the linkage member 6 is in the second position, and the axial ends of the adapter tooth 61 are transmission-connected to the slot 311 and the adapter slot 41 respectively, and when the control component 8 determines that the drive of the drive member 2 fails (the failure judgment method can adopt the Hall sensor mentioned above), the control component 8 can control the linkage member 6 to move from the second position to the first position. An electromagnet may be provided inside the second shaft 4. The electromagnet generates magnetism after being energized. The electromagnet is located at the end of the adapter slot 41 that is away from the card slot 311. The electromagnet is electrically connected to the control component 8. When the control component 8 determines that the drive of the driving member 2 has failed, it energizes the electromagnet to make the electromagnet generate magnetism. A magnetic pole is provided at the end of the linkage member 6 facing the adapter slot 41. The magnetic pole of the linkage member 6 and the magnetism generated by the electromagnet are of opposite polarity. For example, if the magnetic pole of the linkage member 6 is the S pole, the magnetism generated by the electromagnet should be the N pole. In this way, the linkage member 6 can be attracted to the first position, that is, the connection between the first shaft 3 and the second shaft 4 is disconnected. As a result, the control component 8 controls the linkage member 6 to move from the second position to the first position, which is the preset action performed by the control component 8 when the drive of the driving member 2 fails.

[0070] Such an arrangement can quickly and effectively disconnect the connection between the driving member 2 and the output shaft 7. The power of the driving member 2 can only be transmitted to the first shaft 3. Regardless of whether the operation of the driving member 2 is reliable, it will not affect the second shaft 4 and the output shaft 7, thereby effectively avoiding the complete loss of control of the valve body adjustment process due to the loss of control of the operation of the driving member 2, causing safety hazards.

[0071] In some embodiments, please refer to the attached instructions. Figure 3 To Attachment Figure 5 The sliding chamber 31 passes through both ends of the first shaft 3 along the axial direction of the first shaft 3, and an inserting groove 62 is provided at the end of the linkage member 6 away from the adapting tooth 61. The inserting groove 62 corresponds to the port of the sliding chamber 31. The external tool outside the valve opening adjustment device can enter the first shaft 3 through the penetrating sliding chamber 31 and dock with the inserting groove 62 of the linkage member 6.

[0072] In combination with the above, when the driving member 2 is powered off due to external reasons, that is, the driving member 2 stops running and cannot provide power for the driving shaft 21, after the control component 8 is informed of the driving failure of the driving member 2 and executes a preset action, the operator can connect the linkage member 6 through an external tool, and by pushing the linkage member 6, the linkage member 6 is moved from the second position to the first position, that is, the adapter tooth 61 is only engaged with the adapter groove 41 of the second shaft 4. The operator rotates the external tool to drive the second shaft 4 to rotate, and the output shaft 7 connected to the second shaft 4 drives the valve body to adjust the valve body opening.

[0073] Please continue to refer to the instruction manual Figure 4 With attached Figure 5 A prompt device 91 is provided on the inner wall of the adapting groove 41 or the end face of the linkage member 6. In one embodiment of the present invention, the prompt device 91 is provided on the end face of the linkage member 6 close to the adapting groove 41. The prompt device 91 is configured so that when the linkage member 6 moves from the second position to the first position, the control component 8 controls the prompt device 91 to operate, prompting the operator that the adapting groove 41 is only engaged with the adapting tooth 61.

[0074] A prompt device 92 is provided in the inner cavity of the insertion groove 62. The prompt device 92 is configured so that when the external tool is fully inserted into the insertion groove 62, the external tool abuts against the prompt device 92, and the prompt device 92 is activated to inform the operator that the external tool has been installed in place and the valve body can be manually debugged. Among them, the prompt device 91 and the prompt device 92 can be set as elastic sounding parts. When deformed by being triggered, the elastic sounding parts can make an obvious "click" sound to remind the operator that the installation is in place at this time, which effectively improves the convenience of the installation process and ensures the reliability of the installation process.

[0075] In some embodiments, please refer to the attached instructions. Figure 6 With attached Figure 7 A receiving chamber 32 is provided at one end of the first shaft 3 where the slot 311 is provided. At this time, the receiving chamber 32 is connected to the slot 311 and the sliding chamber 31. The receiving chamber 32, the slot 311 and the sliding chamber 31 are arranged in sequence toward the side away from the second shaft 4.

[0076] The accommodating chamber 32 is rotatably connected to one end of the second shaft 4 with an adapting groove 41, and the first shaft 3 and the second shaft 4 are coaxially arranged. When the linkage member 6 is located in the first position, the second shaft 4 can rotate in the accommodating chamber 32. That is to say, when the driving member 2 is in a driving failure state, the control component 8 controls the linkage member 6 to move to the first position, the first shaft 3 is separated from the second shaft 4, and the rotating driving shaft 21 only drives the first shaft 3 to rotate, and the second shaft 4 loses the driving power from the driving member 2, thereby avoiding the occurrence of accidents.

[0077] A radial protrusion 42 is provided on the outer periphery of the second shaft 4, and the radial protrusion 42 is coaxially arranged with the second shaft 4. When the adapting groove 41 is matched with the accommodating chamber 32 of the first shaft 3, the end face of the first shaft 3 abuts against the radial protrusion 42. The radial protrusion 42 is used to limit the axial freedom of the first shaft 3 and the second shaft 4.

[0078] The linkage member 6 includes a rod body 63, one end of which is provided with an adaptor tooth 61. The rod body 63 can be slidably arranged in the sliding chamber 31. A shoulder 51 is provided at the connection between the sliding chamber 31 and the slot 311, that is, the aperture size of the slot 311 is slightly larger than the aperture size of the sliding chamber 31. After the transmission member extends into the inner cavity of the slot 311, the adaptor tooth 61 abuts against the shoulder 51. The shoulder 51 also limits the axial freedom of the adaptor tooth 61, thereby preventing the linkage member 6 from sliding into the sliding chamber 31, resulting in the linkage member 6 being unable to connect the first shaft 3 and the second shaft 4.

[0079] Please refer to the instruction manual Figure 1 The first shaft 3 and the second shaft 4 are coaxially arranged, the first shaft 3 and the driving shaft 21 are vertically arranged, the driving shaft 21 and the output shaft 7 are parallel to each other and not colinear, wherein the driving shaft 21 vertically passes through the substrate 1 and is connected to the driving member 2 on the other side of the substrate 1, the driving shaft 21 and the output shaft 7 are respectively arranged at the two ends of the first shaft 3 and the second shaft 4 along the thickness direction of the substrate 1, and the end of the output shaft 7 away from the substrate 1 is connected to the valve body. Worm gear connection can be adopted between the driving shaft 21 and the first shaft 3, and between the second shaft 4 and the output shaft 7.

[0080] An elastic member 11 is provided between the adapter groove 41 and the linkage member 6. The elastic member 11 extends along the axis direction of the second shaft 4. The elastic member 11 supports the linkage member 6. The end of the linkage member 6 abuts against the shaft shoulder 51, so that the adapter tooth 61 always has a tendency to remain in the second position, that is, when the driving member 2 is operating normally, the linkage member 6 is only subjected to the elastic force of the elastic member 11. The elastic member 11 abuts against the linkage member 6, so that the linkage member 6 is located in the second position. At this time, the first shaft 3 and the second shaft 4 are fixedly connected and can rotate synchronously. In addition, when the driving of the driving member 2 fails, the elastic member 11 is gradually compressed in the process of the linkage member 6 moving to the first position, increasing the elastic potential energy of the elastic member 11. When the driving of the driving member 2 is normal, the elastic member 11 releases the elastic potential energy and pushes the linkage member 6 to the second position.

[0081] Please refer to the instruction manual Figure 2 The second shaft 4 is also connected to the connecting shaft 10 through the output shaft 7. The end of the output shaft 7 away from the valve body extends and passes through the substrate 1. A first gear coaxial with the output shaft 7 is provided on the other side of the substrate 1. The first gear is meshed with the second gear, and the second gear is coaxially connected to the connecting shaft 10. A feedback device 16 is provided at the end of the connecting shaft 10 away from the second gear. The rotation angle of the valve body is calculated by the rotation angle of the connecting shaft 10, so that the operator can observe the opening change of the valve body in real time.

[0082] Please refer to the instruction manual Figure 1 With attached Fig. 9 A first half shell 12 and a second half shell 13 are respectively provided on both sides of the substrate 1 along its thickness direction. The first half shell 12 and the second half shell 13 clamp and fix the substrate 1, and a sealing ring is provided around the edge of the substrate 1 to ensure the sealing of the valve opening adjustment device. The driving member 2 is arranged between the first half shell 12 and the member. A mounting groove is also provided on the substrate 1, and a first gear and a second gear that mesh with each other are provided in the mounting groove. The control component 8 can be specifically a control board. The control component 8 is covered on the mounting groove to seal the inner cavity of the mounting groove to prevent external debris from entering the mounting groove and affecting the meshing of the first gear and the second gear. In addition, an energy supply device can be provided on the side of the control component 8 away from the substrate 1. The energy supply device can be specifically the external power supply recorded above. The energy supply device is electrically connected to the driving member 2, the Hall sensor, and the control component 8 to provide electrical energy.

[0083] An observation window is provided at a position corresponding to the feedback device 16 of the first half shell 12, and a plurality of heat sinks 14 are provided on the side wall of the second half shell 13. The heat sink 14 is used to guide the heat released by the operation of the driving member 2 so that each component can work in a suitable environment. In addition, a connecting hole 15 is provided at a position corresponding to the insertion groove 62 of the second half shell 13. The connecting hole 15 allows an external tool to enter the second half shell 13 and complete the insertion on the linkage member 6.
