Description

Technical Field

[0001] The utility model belongs to the field of valves, and in particular relates to an air volume regulating valve. Background Art

[0002] The air volume control valve, also known as the damper, is a valve body structure that adjusts the air volume in the pipeline. It is widely used in HVAC systems in industrial and mining industries and civil buildings, or in air ducts in the semiconductor industry and chemical engineering to accurately adjust the air flow. It is one of the key devices for achieving ventilation mode control in various environments.

[0003] Most existing air volume control valves have a rotating shaft mounted on a blade sized to fit the valve's interior. The shaft drives the blades to open and close the valve. However, these valves lack flexibility and stability when adjusting air volume. Utility Model Content

[0004] In view of the above problems, the purpose of the present invention is to provide an air volume regulating valve, aiming to solve the problems of the existing air volume regulating valve being insufficiently flexible and having poor stability.

[0005] The utility model adopts the following technical solutions:

[0006] The air volume regulating valve includes a rotating seat, a valve body is slidingly provided in the rotating seat, a circle of shaft sleeves is provided on the valve body, a linkage shaft is rotatably provided in each shaft sleeve, an adjusting blade is provided at the inner end of the linkage shaft, and a linkage plate is provided at the outer end, an intermediate shaft is rotatably provided on the linkage plate, a fixed shaft is rotatably provided on the intermediate shaft, and the fixed shaft is installed on the rotating seat, any linkage shaft passes through the linkage plate and is provided with a rotating shaft, and a fixed seat for installing a drive motor is also provided on the valve body, and the drive shaft of the drive motor is connected to the rotating shaft.

[0007] Furthermore, upper and lower connecting seats are respectively provided at both ends of the valve body.

[0008] Furthermore, the upper connecting seat is formed with a plurality of protrusions, each of which is rotatably provided with a limiting sliding wheel, and the rotating seat is slidably connected to the valve body through the limiting sliding wheel.

[0009] Furthermore, the upper connecting seat is formed with a side plate, an arc-shaped groove is opened on the side plate, a long plate is provided on the rotating seat, a guide stud is screwed into the bottom of the long plate, and the guide stud passes through the arc groove and is screwed into a limiting nut.

[0010] The beneficial effect of the present utility model is that when the air volume control valve is used to adjust the air flow in a pipeline, the drive motor drives the corresponding linkage shaft to rotate, and the linkage plate on the linkage shaft rotates synchronously, driving the intermediate shaft on it to rotate. Driven by the intermediate shaft, the rotating seat rotates, and the rotating seat then drives the remaining intermediate shafts to rotate, so that all the linkage plates are linked. Driven by the linkage plate, the linkage shaft drives the regulating blade to rotate, thereby adjusting the opening size in the valve body and regulating the air flow in the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 2 This utility model provides a schematic diagram of the installation of the intermediate shaft. DETAILED DESCRIPTION

[0013] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not intended to limit the utility model.

[0014] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0015] For the sake of convenience, only the parts related to the embodiments of the present invention are shown.

[0016] Combine Figure 1-2 As shown, the air volume regulating valve includes a rotating seat 1, in which a valve body 2 is slidingly provided, and a circle of shaft sleeves 3 is provided on the valve body 2. A linkage shaft 4 is rotatably provided in each shaft sleeve 3, and an adjusting blade 5 is provided at the inner end of the linkage shaft 4, and a linkage plate 6 is provided at the outer end. An intermediate shaft 7 is rotatably provided on the linkage plate 6, and a fixed shaft 8 is rotatably provided on the intermediate shaft 7. The fixed shaft 8 is installed on the rotating seat 1, wherein any linkage shaft 4 passes through the linkage plate 6 and is provided with a rotating shaft 9. A fixed seat 10 for installing a drive motor is also provided on the valve body 2, and a drive shaft of the drive motor (not shown in the figure) is connected to the rotating shaft.

[0017] As we all know, the air volume control valve, also known as the damper, is a valve body structure that adjusts the air volume in the pipeline. It is widely used in HVAC systems in industrial and mining industries and civil buildings, or in air ducts in the semiconductor industry and chemical engineering to accurately adjust the air flow. It is one of the key devices for achieving ventilation mode control in various environments.

[0018] The two ends of the valve body 2 are respectively provided with an upper and a lower connecting seat 11. The two ends of the air volume regulating valve are installed between two sections of pipelines through the upper and lower connecting seats.

[0019] When using this air volume control valve to adjust the air flow in a pipeline, the drive motor drives the corresponding linkage shaft to rotate. Simultaneously, the linkage plate on the linkage shaft rotates synchronously, driving the intermediate shaft on it. Driven by the intermediate shaft, the rotating seat rotates, which in turn drives the remaining intermediate shafts, thus synchronizing all the linkage plates. Driven by the linkage plate, the linkage shaft drives the regulating vanes to rotate, thereby adjusting the opening size in the valve body and regulating the air flow in the pipeline. This provides greater stability and flexibility during the adjustment process.

[0020] In this structure, the upper connecting seat 11 is formed with a plurality of protrusions 12 , and a limiting sliding wheel 13 is rotatably provided on each protrusion 12 . The rotating seat 1 is slidably connected to the valve body 2 via the limiting sliding wheel 13 .

[0021] When the driving motor drives the rotating shaft to rotate, the rotating seat will rotate relative to the valve body under the action of the limiting sliding wheel during this process. In this process, the limiting sliding wheel also plays the role of limiting the installation of the rotating seat.

[0022] As a preferred structure, Figure 1 The upper connecting seat is formed with a side plate 14, and an arc groove 15 is opened on the side plate 14. The rotating seat 1 is provided with a long plate 16, and a guide stud 17 is screwed into the bottom of the long plate 16. The guide stud 17 passes through the arc groove 15 and is screwed into a limiting nut 18.

[0023] In this structure, the limit nut is not tightened. When the rotating seat rotates, the long plate rotates synchronously. The guide stud slides within the arcuate groove. When the guide stud slides from one end of the arcuate groove to the other, the valve body is fully opened. The guide stud serves as a guide and limiter, further enhancing the stability of the valve when opening or closing.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
