Description

Technical Field

[0001] This utility model relates to an exhaust ventilation regulating device, specifically an exhaust ventilation regulating device, belonging to the field of exhaust ventilation equipment technology. Background Technology

[0002] Exhaust ventilation control devices are core control components in ventilation and air handling systems, widely used in various settings such as industrial plants, laboratories, commercial buildings, and underground parking garages. Their core working principle involves manually or electrically driving a mechanism to adjust the rotation angle of a valve plate within the connecting pipe, thereby changing the cross-sectional area of ​​the air duct. This achieves precise control of exhaust volume, pressure balance, and airflow direction adjustment, playing a crucial role in ensuring indoor air quality, maintaining stable production processes, reducing system energy consumption, and meeting fire-fighting smoke extraction requirements.

[0003] However, when adjusting the angle of the exhaust regulating device, the operator needs to rely on personal experience to judge the actual opening and closing state of the valve plate, which makes it difficult to accurately control the adjustment precision. This experience-based adjustment method is prone to deviations in air volume control, which will not only directly affect the operation of the ventilation and air handling system, but may also cause unnecessary energy waste due to improper air volume adjustment. Ultimately, it will fail to meet the scenario's demand for refined air volume control. At the same time, the valve plate itself achieves the sealing of the pipe. When the valve plate is rotated to the sealed state, a small gap may still remain between the valve plate and the pipe wall, resulting in poor sealing effect and easy exhaust leakage problems.

[0023] As a technical optimization of this utility model, a connecting post 305 is fixedly connected to the connecting pipe 1, a rubber rope 306 is provided on the connecting post 305, and a sealing cover 307 is fixedly connected to the rubber rope 306. When not in use, the rubber rope 306 on the connecting post 305 can be rotated to cover the scale ring 303 with the sealing cover 307. The sealing cover 307 covers the scale ring 303 to form physical protection, which can prevent dust from adhering and causing the scale to become blurred, and prevent moisture or corrosive media from damaging the scale ring 303. This ensures that the scale is clear for a long time and can stably perform the angle indication function, thus extending the service life of the scale ring 303. The sealing cover 307 can protect the scale ring 303.

[0024] As a technical optimization of this utility model, the mounting plate 401 is provided with a positioning groove 407 that cooperates with the positioning ring 402. The valve plate 2 is fixedly connected with a positioning post 405. The mounting plate 401 on the valve plate 2 cooperates with the positioning post 405 on the valve plate 2 through the assembly plate 404, and is then fixed by bolts and threaded holes 406, which facilitates installation and replacement. The positioning ring 402 is embedded in the positioning groove 407 of the mounting plate 401, which enhances the structural stability. The fixed rubber ring 403 can tightly fit the inner wall of the connecting pipe 1 when the valve plate 2 is closed, which improves the sealing performance of the device and reduces exhaust leakage. The rubber ring 403 and the assembly plate 404 are slidably connected to the positioning post 405. The positioning post 405 is provided with a threaded hole 406. The assembly plate 404 is fixed by bolts cooperating with the threaded hole 406.

[0025] As a technical optimization of this utility model, the valve plate 2 is adjusted by the adjustment structure 5. The adjustment structure 5 includes a positioning frame 501, which is fixedly connected to the valve plate 2. A plug 502 is slidably connected to the positioning frame 501, and a drive shaft 503 is fixedly connected to the plug 502. The drive shaft 503 is rotatably connected to the connecting pipe 1, and a connecting seat 504 is fixedly connected to the connecting pipe 1. The drive shaft 503 is rotatably connected to the connecting seat 504, and an installation box 505 is installed on the connecting seat 504. The drive shaft 503 is rotatably connected to the installation box 505. A worm gear 506 is fixedly connected to the drive shaft 503, and a worm 507 meshes with the worm gear 506. First, the connecting... Pipe 1 is connected to the exhaust duct system. When the exhaust volume needs to be adjusted, the operator turns the handwheel 508. The handwheel 508 drives the worm gear 507 to rotate inside the mounting box 505. Because the worm gear 507 meshes with the worm wheel 506, the worm wheel 506 drives the drive shaft 503 to rotate. The drive shaft 503 drives the valve plate 2 to rotate inside the connecting pipe 1 through the cooperation of the insert block 502 and the positioning frame 501. Through the self-locking characteristics of the worm wheel 506 and the worm gear 507, the adjustment angle of the valve plate 2 can be accurately maintained, avoiding angle deviation caused by external forces such as wind. Moreover, the operation through the handwheel 508 is more labor-saving. The worm gear 507 is rotatably connected to the mounting box 505, and the handwheel 508 is fixedly connected to the worm gear 507.

[0026] In use, the connecting pipe 1 is first connected to the exhaust duct system. When the exhaust volume needs to be adjusted, the operator turns the handwheel 508. The handwheel 508 drives the worm gear 507 to rotate within the mounting box 505. Because the worm gear 507 meshes with the worm wheel 506, the worm wheel 506 drives the transmission shaft 503 to rotate. The transmission shaft 503, through the cooperation of the insert block 502 and the positioning frame 501, drives the valve plate 2 to rotate within the connecting pipe 1. The self-locking characteristic of the worm wheel 506 and the worm gear 507 accurately maintains the adjustment angle of the valve plate 2, preventing angle deviation caused by external forces such as wind. Furthermore, operation via the handwheel 508 is more labor-saving. When the valve plate 2 rotates, its fixed mounting block 301 drives the mounting shaft 302 and the marking block 304 to rotate synchronously. The marking block 304 cooperates with the scale ring 303 fixed on the connecting pipe 1, visually displaying the rotation angle of the valve plate 2. The operator can directly observe the rotation angle of the valve plate 2 through the cooperation between the marking block 304 and the scale ring 303. By observing and controlling the rotation angle of valve plate 2, the exhaust volume can be precisely controlled, improving the convenience and accuracy of adjustment operations. When not in use, the rubber rope 306 on the connecting column 305 can be rotated to cover the scale ring 303 with the sealing cover 307. The sealing cover 307 forms a physical protection on the scale ring 303, which can prevent dust from adhering and causing the scale to become blurred, or moisture or corrosive media from damaging the scale ring 303. This ensures that the scale is clear for a long time and can stably perform its angle indication function, extending the service life of the scale ring 303. The mounting plate 401 on valve plate 2 cooperates with the positioning column 405 on valve plate 2 through the assembly plate 404, and is then fixed by bolts and threaded holes 406, which facilitates installation and replacement. The positioning ring 402 is embedded in the positioning groove 407 of the mounting plate 401, which enhances the structural stability. Its fixed rubber ring 403 can fit tightly against the inner wall of the connecting pipe 1 when valve plate 2 is closed, improving the sealing performance of the device and reducing exhaust leakage.
