Embodiment 1

[0033] Please refer to Figure 2 to Figure 4 , This embodiment provides an air valve 10, which is suitable for a circular air duct. The air valve 10 includes a cylindrical tube with an interlayer and a circular arc slide 3. One end of the cylindrical tube is open. When in use, the open end is connected to the circular air duct, so that the inner channel of the cylindrical tube is connected to the circular air duct. Air ducts are connected. The other end of the cylindrical tube is sealed. A vent is provided on the side wall of the cylindrical tube. The circular arc sliding piece 3 is arranged on the interlayer of the cylindrical tube, and the circular arc sliding piece 3 can close or open the ventilation opening under the driving of the driving device 4 .

[0034] In this embodiment, the output of the driving device 4 is linear motion, that is, the arc sliding vane 3 is driven by the driving device 4 to perform linear motion.

[0035] The cylindrical tube includes an inner ...

Embodiment 2

[0044]This embodiment is further improved on the basis of Embodiment 1. In this embodiment, the cylindrical tube of the air valve 10 in Embodiment 1 is improved, and other structures are the same as those of Embodiment 1. In this example, both ends of the cylindrical tube in Example 1 are set to be open, that is, both ends of the inner cylindrical sleeve 1 of the cylindrical tube in Example 1 are set to be open. When the air valve 10' of this embodiment is used, it is necessary to connect the two ends of the cylindrical pipe of the air valve 10' to the port of a circular air pipe respectively. Please refer to Figure 7 , for example, the air valve 10' described in Embodiment 2 is provided between the circular air duct 1 20 and the circular air duct 2 30, and the air valve described in Embodiment 1 is provided at the end of the circular air duct 2 30 10.

Embodiment 3

[0046] This embodiment is further improved on the basis of Embodiment 1 and Embodiment 2. In this embodiment, please refer to Figure 8 , the drive motor is arranged on the outside of the cylindrical tube, the purpose is to facilitate the maintenance of the drive motor.

Abstract

The invention provides an air valve which comprises a cylindrical pipe with an interlayer and an arc slip sheet, and at least one end of the cylindrical pipe is open; a ventilation opening is formed in the side wall of the cylindrical pipe; the arc sliding piece is arranged on the interlayer of the cylindrical pipe and can close or open the ventilation opening under driving of a driving device.

Description

technical field [0001] The invention belongs to the technical field of electric air valves. Background technique [0002] With the development of air-conditioning technology, pneumatic technology and airflow conveying technology, it has become an indispensable and important requirement to implement online precise control technology for the direction and flow of air flow in the pipeline. like figure 1 As shown in the figure, the commonly used pipeline electric air valve, three rotary valve plates (blades) are linked by connecting rods, and a drive motor drives the opening and closing of the three valve plates. [0003] The rotary electric air valve connected in the airflow pipeline is easy to install, simple, reliable and economical. [0004] However, this rotary electric air valve also has obvious shortcomings, mainly due to relatively poor sealing performance, high air leakage rate, poor mechanical strength, and weak deformation resistance of the valve plate.
