[0002] With the rapid development of modern industrial technology, the design and application of building ventilation systems have made remarkable progress. In buildings, factories and other industrial facilities, the ventilation system is a key device to ensure the indoor air quality and the comfort of the working environment. The ventilation system usually includes various pipelines and air valve devices. Through these devices, the air flow can be adjusted, and the temperature and humidity can be controlled, so as to effectively manage the air quality.

[0003] Most of the common air valve devices in traditional ventilation systems adopt a partial sealing design. Although this design can achieve the regulation of air flow to a certain extent, there are often some problems in the actual application process. Due to insufficient sealing performance, traditional air valves often have air leakage phenomena in the closed state, resulting in energy waste and low efficiency of the ventilation system. At the same time, air leakage may also introduce pollutants and affect the indoor air quality. Summary of the Invention

Those skilled in the art know that for traditional air valve devices, due to insufficient sealing performance, air leakage often occurs in the closed state, resulting in energy waste and low efficiency of the ventilation system. At the same time, air leakage may also introduce pollutants and affect the indoor air quality.

[0028] In this embodiment, a wind valve housing 2 is arranged inside the pipeline 1. A first frame 3 and a second frame 4 are slidably connected inside the wind valve housing 2. A plurality of flow blocking vanes 5 are arranged between the inside of the first frame 3 and the inside of the second frame 4. Both sides of one end of the plurality of flow blocking vanes 5 are rotatably connected inside the first frame 3 through a rotating shaft. Both sides of the other end of the plurality of flow blocking vanes 5 are rotatably connected inside the second frame 4 through a rotating shaft. A sealing block 51 is fixedly connected to one end of the plurality of flow blocking vanes 5 away from the second frame 4. Slots 52 are formed on the side surfaces of the plurality of flow blocking vanes 5. A sealing assembly 6 is arranged in the slots 52. An adsorption assembly for cooperating with the sealing block 51 is arranged on the top surface of the sealing assembly 6. The top of the end surface of the first frame 3 away from the second frame 4 is fixedly connected with a fixing frame 7. A driving assembly is arranged on the end surface of the fixing frame 7 away from the first frame 3.

[0029] By arranging a plurality of flow blocking vanes 5 between the inside of the first frame 3 and the inside of the second frame 4, when the driving assembly applies a downward force to the first frame 3, the first frame 3 moves downward inside the wind valve housing 2, and at the same time applies a downward force to the internal flow blocking vanes 5, causing the other end of the flow blocking vanes 5 to move to one side through the rotating shaft connected to the second frame 4, so that the plurality of flow blocking vanes 5 are closed. When the flow blocking vanes 5 are closed, there is a certain gap between two adjacent flow blocking vanes 5. By arranging the sealing block 51, the gap between two adjacent flow blocking vanes 5 can be sealed, thereby improving the sealing performance of the device.

[0030] Moreover, in this embodiment, the driving assembly includes a telescopic cylinder 8 and a support frame 9. The support frame 9 is fixedly connected to the inner wall of the pipeline 1. One end of the telescopic cylinder 8 is fixedly connected to the center of the end surface of the fixing frame 7, and the other end of the telescopic cylinder 8 is fixedly connected to the end surface of the support frame 9.

[0031] The telescopic cylinder 8 is arranged above the end surface of the first frame 3 through the support frame 9, which is a certain distance away from the wind valve housing 2 to a certain extent. And complex installation structures such as bearings are eliminated, reducing the failure of the driving assembly caused by heat conduction, reducing the leakage of air and oil caused by the damage of bearings and the like, prolonging the service life of the wind valve device, and the height of the support frame 9 can also be increased according to requirements, making the telescopic cylinder 8 further away from the wind valve housing 2 and further protecting the driving assembly.

[0032] Moreover, in this embodiment, a protective cover 91 is fixedly connected to the end surface of the support frame 9, and the telescopic cylinder 8 is fixedly connected inside the protective cover 91.

[0033] By arranging the protective cover 91, the telescopic cylinder 8 is arranged inside the protective cover 91 to further protect the telescopic cylinder 8.

[0034] In addition, in this embodiment, the first frame 3 can slide up and down inside the wind valve housing 2, and the second frame 4 can slide left and right inside the wind valve housing 2.

[0035] Driven by the driving component, the first frame 3 can cooperate with the second frame 4 to open or close a plurality of flow blocking vanes 5.

[0036] In addition, in this embodiment, the sealing component 6 includes a sealing slide plate 61, a sealing strip 62 and a tension spring 63. The sealing slide plate 61 is slidably connected to the inner surface of the slot 52. The sealing strip 62 is bonded to the side surface of the sealing slide plate 61 away from the inner bottom surface of the slot 52. A plurality of tension springs 63 are provided. One ends of the plurality of tension springs 63 are fixedly connected to the inner bottom surface of the slot 52, and the other ends of the plurality of tension springs 63 are fixedly connected to the side surface of the sealing slide plate 61. The adsorption component includes a first magnetic sheet 621 and a second magnetic sheet 511 magnetically attracted to the first magnetic sheet 621. A first notch is formed on the end surface of the sealing strip 62, and the first magnetic sheet 621 is fixedly connected inside the first notch. A second notch is formed on the end surface of the sealing block 51, and the second magnetic sheet 511 is fixedly connected inside the second notch. Two limiting grooves are formed on the side surface of the sealing slide plate 61, and two limiting blocks are fixedly connected to the inner surface of the slot 52, and the two limiting blocks are respectively slidably connected in the two limiting grooves.

[0037] By providing the sealing component 6 and the adsorption component, when adjacent flow blocking vanes 5 approach and close to each other, the sealing block 51 provided on one flow blocking vane 5 approaches the side surface of another flow blocking vane 5. The first magnetic sheet 621 provided on the end surface of the sealing strip 62 is magnetically attracted to the second magnetic sheet 511 provided on the end surface of the sealing block 51, driving the sealing slide plate 61 to slide outward to the slot 52 until the sealing strip 62 and the sealing block 51 are tightly magnetically attracted to each other, further improving the tightness between two adjacent flow blocking vanes 5; when the flow blocking vanes 5 are opened, the sealing strip 62 and the sealing block 51 move away from each other, and under the action of the tension spring 63, the sealing slide plate 61 and the sealing strip 62 are pulled back into the slot 52.

[0038] In addition, in this embodiment, both the sealing block 51 and the sealing strip 62 are made of heat-resistant rubber material.

[0039] The sealing block 51 and the sealing strip 62 made of heat-resistant rubber material not only have a certain elasticity, but also can withstand the high-temperature gas passing through the pipeline 1, reducing air leakage caused by the damage of the sealing block 51 and the sealing strip 62.

[0040] In addition, in this embodiment, sealing gaskets are provided on the outer side surfaces of the peripheries of the first frame 3 and the second frame 4.

[0041] By providing the sealing gaskets, the sealing performance of the air valve device is further improved.

[0043] The influence of sunlight and rain on the driving component can be reduced by the provided rain-proof cap 10.

[0044] During use, the telescopic cylinder 8 is started to extend downward, thereby driving the first frame body 3 to move downward in the air valve housing 2. At the same time, a downward force is applied to the flow-blocking blades 5 inside, so that the other end of the flow-blocking blade 5 drives the second frame body 4 rotatably connected through a rotating shaft to move to one side, thereby closing the multiple flow-blocking blades 5; when the flow-blocking blades 5 are closed, there is a certain gap between two adjacent flow-blocking blades 5. By the provided sealing block 51, the gap between two adjacent flow-blocking blades 5 can be sealed, thereby improving the sealing performance of the device; at the same time, the sealing block 51 provided on one flow-blocking blade 5 is close to the side surface of another flow-blocking blade 5. The first magnetic sheet 621 provided on the end surface of the sealing strip 62 is magnetically attracted to the second magnetic sheet 511 provided on the end surface of the sealing block 51, driving the sealing slide plate 61 to slide outward to the slot 52 until the sealing strip 62 and the sealing block 51 are tightly magnetically attracted to each other, further improving the tightness between two adjacent flow-blocking blades 5.
