Description

Technical Field

[0001] This utility model belongs to the field of HVAC control technology, specifically relating to a novel intelligent proportional control actuator. Background Technology

[0002] Actuators are used in radiant heating / cooling systems in the HVAC industry. They mainly consist of a motor, transmission mechanism, regulating mechanism, and actuator. Installed on the control valve in the pipeline, they automatically adjust the valve opening based on the user's temperature requirements and the real-time water temperature in the pipeline, thus achieving the desired operating temperature. Most existing actuators are integrated, resulting in limited installation and often requiring compatibility with only their own valves. Furthermore, the rotation of internal transmission components relies on grease and self-lubrication; over time, the grease dries out, affecting the operation of the entire transmission mechanism and leading to decreased accuracy or even actuator failure. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems by providing a novel intelligent proportional control actuator.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: A novel intelligent proportional adjustment actuator includes an actuator housing with a mounting cavity. A rotary handle is located at the upper end of one side of the actuator housing. A transmission main shaft, radially penetrating the actuator housing and connected to the rotary handle, is located on the inner side of the upper end of the actuator housing. A gearbox is located inside the actuator housing, and a gear assembly with several rotating bearings is located inside the gearbox. The rotating bearings are sleeved on the outside of the transmission main shaft. A drive control component connected to the gear assembly is located on one side of the gearbox. A gear release structure, enabling the gear assembly to disengage and thus allowing manual rotation of the rotary handle, is located at the lower end of the actuator housing near the rotary handle. A rotating fixing component connected to a valve is located on the side of the actuator housing away from the rotary handle. The installation of rotating bearings within the gear assembly improves the overall smoothness of the gear assembly's rotation, preventing jamming. The gear release structure allows for manual adjustment of the rotary handle, improving practicality. Simultaneously, the drive control component enables the actuator to achieve self-control. Furthermore, the actuator employs a split-type design, allowing for design and adjustment according to various valve types, resulting in high adaptability.

[0005] In the aforementioned novel intelligent proportional control actuator, the actuator housing has an upper housing and a lower housing, the gearbox is disposed between the upper housing and the lower housing, the gearbox has a gear mounting cavity, and the gearbox has a gearbox base that can close the gear mounting cavity on the side of the gearbox near the lower housing.

[0006] In the aforementioned novel intelligent proportional control actuator, the drive control component includes a control board disposed on the side of the gearbox near the upper housing. A drive motor is connected to the control board on the side near the gearbox, and the output shaft of the drive motor extends into the gearbox and is connected to a gear assembly. The drive motor serves as the power source, and the gear assembly transmits and amplifies the output force of the drive motor, ultimately acting on the transmission main shaft. Simultaneously, the control board achieves automatic control.

[0007] In the aforementioned novel intelligent proportional control actuator, the upper housing is fixedly connected to one side of the gearbox via several snap fasteners, and the lower housing is fixedly connected to the other side of the gearbox via several screws.

[0008] In the aforementioned novel intelligent proportional adjustment actuator, the gear assembly includes a motor connector disposed within a gear mounting cavity and connected to a drive motor. One end of the motor connector is provided with a drive master gear, which meshes with a drive driven gear disc. One end of the drive driven gear disc is provided with a drive driven gear, which meshes with a release gear disc. One end of the release gear disc is provided with a release gear, which meshes with a first transmission gear disc. One end of the first transmission gear disc is provided with a first transmission gear, which meshes with a second transmission gear disc. One end of the second transmission gear disc is provided with a second transmission gear, which meshes with a main shaft connector. The other end of the second transmission gear disc is provided with an angle transmission gear. An angle transmission gear disc meshing with the angle transmission gear is located on the outer side of the gearbox, and the end of the angle transmission gear disc furthest from the angle transmission gear is connected to a control board. The motor connector is connected to the drive motor, the drive main gear is connected to the drive driven gear, the drive driven gear is connected to the release gear, the release gear is connected to the first transmission gear, the first transmission gear is connected to the second transmission gear, the second transmission gear is connected to the main shaft connector, and at the same time, the angle transmission gear is connected to the angle transmission gear. The function of the angle transmission gear is to transmit the rotation angle of the main shaft connector to the control board.

[0009] In the aforementioned novel intelligent proportional adjustment actuator, the main shaft connector has a connecting portion through which the transmission main shaft passes axially. Rotary bearings are respectively disposed on both sides of the connecting portion. A semi-circular arc-shaped gear is provided on one side of the connecting portion, and this arc-shaped gear meshes with a second transmission gear. The use of rotary bearings to connect to the rotary handle improves the smoothness of the overall rotational operation of the gear assembly.

[0010] In the aforementioned novel intelligent proportional control actuator, the gear release structure includes a release rod disposed on the side of the release gear disc away from the drive gear. One end of the release rod has an axially extending reset groove on its inner circumferential side. The lower end of the release rod has a release portion with a release groove inside. The outer side of the release gear disc is disposed within the release groove. A release space exists between the release gear disc and the release gear. The release rod is equipped with a gear release assembly that allows the release gear disc and the release gear to move axially, thereby disengaging the first transmission gear disc from the release gear or re-engaging it. When the release gear disc is driven by the release rod, the first transmission gear disc is positioned within the release space, causing the release gear to disengage from the first transmission gear disc, thus completing the gear release action.

[0011] In the aforementioned novel intelligent proportional adjustment actuator, the gear release assembly includes a button located at the end of the actuator housing furthest from the rotary handle. The button is connected to the end of the release lever furthest from the release groove. A reset post corresponding to the release lever is located at one end of the gearbox base. The reset post is positioned within a reset groove, and a reset spring, in contact with the release lever, is sleeved on the outside of the reset post. Pressing the button moves the release lever, which in turn moves the release gear downwards via the release part, disengaging the release gear from the first transmission gear. The first transmission gear is then positioned within the release space, allowing manual rotation of the rotary handle. After manual adjustment, releasing the button causes it to return to its original position via the reset spring. Simultaneously, the release gear re-engages with the first transmission gear.

[0012] In the aforementioned novel intelligent proportional control actuator, a valve connection portion is provided at the upper end of the lower housing, away from the upper housing. The rotating fixing component is located on the outer side of the valve connection portion, away from the lower housing. O-rings are provided between the rotating handle and the upper housing, between the transmission shaft and the valve connection portion, and between the button and the upper housing. The O-rings provide a sealing function during assembly, and the rotating fixing component is used to fix the lower housing and the valve together, ultimately securing the entire actuator to control the opening and closing degree of the valve.

[0013] In the aforementioned novel intelligent proportional control actuator, the rotary handle has a through hole in the middle, an indicator arrow at the lower end of the through hole, and several circumferentially distributed orientation marks at one end of the through hole. The upper housing has an arc-shaped angle scale corresponding to the through hole at one end. After installation, the indicator arrow on the rotary handle points to the arc-shaped angle scale on the upper housing, indicating the current rotation angle of the rotary handle. Installation is simple and convenient; simply align the orientation marks with the valve.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] 1. This device adds a rotating bearing to the gear assembly to connect the transmission shaft, which can improve the smoothness of the overall rotation of the gear assembly and avoid jamming.

[0016] 2. The device separates the main body mechanism and the bottom mounting mechanism. The bottom mounting mechanism can be adapted to different types of valves by adjusting the rotating fixing part and the valve connection part, which improves its practicality.

[0017] 3. The device incorporates additional waterproof sealing rings to enhance overall sealing, achieving a splash-proof and waterproof rating. This prevents damage caused by leaks in pipes in humid environments, thereby extending its service life.

[0018] 4. This device uses a control board and an angle transmission gear plate, thereby adding sensors and communication protocols to achieve the purpose of automatic control. Attached Figure Description

At the same time, the actuator can achieve the purpose of self-control through the drive control component 4. The actuator adopts a split design structure, which can be designed and adjusted according to different types of valves, with high adaptability.

The drive motor 42 is the power source, and the gear assembly 3 transmits and amplifies the output force of the drive motor 42, ultimately acting on the transmission main shaft 12. At the same time, the control board 41 is used to achieve the purpose of automatic control.

[0029] Specifically, the upper housing 14 is fixedly connected to one side of the gearbox 2 by several buckles 22, and the lower housing 15 is fixedly connected to the other side of the gearbox 2 by several screws 23.

[0030] Combination Figure 2 , Figure 3 and Figure 4 As shown, the gear assembly 3 includes a motor connector 31 disposed within the gear mounting cavity and connected to the drive motor 42. One end of the motor connector 31 is provided with a drive master gear 311, which meshes with a drive driven gear disc 32.

The other end of the second transmission gear disk 35 has an angle transmission gear 352. An angle transmission gear disk 43 that meshes with the angle transmission gear 352 is provided on the outside of the gearbox 2, and the end of the angle transmission gear disk 43 away from the angle transmission gear 352 is connected to the control board 41.

The outer side of the release gear 33 is disposed within the release groove 54. A release space 55 exists between the release gear 33 and the release gear 331. The release rod 51 is equipped with a gear release assembly 6 that allows the release gear 33 and the release gear 331 to move axially, thereby disengaging the first transmission gear 34 from the release gear 331 or re-engaging the first transmission gear 34 from the release gear 331. When the release gear 33 is driven by the release rod 51, the first transmission gear 34 is positioned within the release space 55, causing the release gear 331 to disengage from the first transmission gear 34, thus completing the gear release action.

[0033] The gear release assembly 6 includes a button 61 located at the end of the actuator housing 1 away from the rotary handle 11. The button 61 is connected to the end of the release lever 51 away from the release groove 54. One end of the gearbox base 21 is provided with a reset post 62 corresponding to the release lever 51.

The first transmission gear 34 is located in the release space 55. At this time, the rotary handle 11 can be manually rotated. After manual adjustment, the button 61 is released, and the button 61 returns to its original position through the reset spring 63. At this time, the release gear 33 returns to its original position, and the release gear 331 meshes with the first transmission gear 34.

[0034] Specifically, a valve connection portion 16 is provided at the upper end of the housing 15 on the side away from the upper housing 14.

When manually rotating the rotary handle 11, the button 61 is pressed first, and the release lever 51 moves downward under pressure, causing the return spring 53 to tighten.

[0038] The release gear 33 begins to move under the drive of the release part 53, causing the release gear 331 to disengage from the first transmission gear 34. The first transmission gear 34 is located in the release space 55, so the rotary handle 11 can be manually rotated. When it is rotated to the position, the button 61 is released, the return spring 53 begins to reset, the release rod 51 moves upward and drives the release gear 33, so the release gear 331 re-meshes with the first transmission gear 34, and the operation of the gear assembly 3 can achieve the purpose of self-control of the actuator through the control plate 41 and the angle transmission gear 43.
