[0039] The working principle of the present invention:

[0040] Through the settings of the connecting pipe 13 and the gas flowmeter 14, the aeration flow rate passing through the iris valve body can be monitored in real time. When it is necessary to accurately regulate the aeration flow rate of the iris valve body, the unlocking pull block 7 can be first pulled upward. The upward movement of the unlocking pull block 7 will drive the fixed insertion rod 8 out of the fixed insertion hole 9, and the arc-shaped sliding rod 5 will be released. At this time, the control handle 3 can be quickly moved for rough adjustment. After moving to the appropriate position, the unlocking pull block 7 is directly released. Under the elastic force of the return spring 15, the unlocking pull block 7 will be pulled to move downward automatically, and then the fixed insertion rod 8 can be driven to move into the fixed insertion hole 9, automatically fixing the arc-shaped sliding rod 5 all the time. Then, the adjustment knob 17 can be pulled and rotated. The rotation of the adjustment knob 17 will drive the adjustment screw rod 10 to rotate together through the hexagonal connecting rod 16. The rotation of the adjustment screw rod 10 will drive the adjustment moving block 11 to move slowly. Furthermore, the control handle 3 can be driven to move slowly through the connecting rotating rod 12 and the arc-shaped telescopic rod 6 for fine adjustment. According to the reading of the gas flowmeter 14, the aeration flow rate of the iris valve body can be accurately regulated to the specified size. After the regulation is completed, the adjustment knob 17 is released. Under the elastic force of the extrusion spring 22, the adjustment knob 17 will be extruded and pushed to reset automatically, and then the locking insertion rod 21 can be driven to move into the locking insertion hole automatically, fixing the adjustment knob 17 all the time, effectively reducing the situation that the valve body flow rate changes greatly due to accidentally touching the adjustment knob 17, and having good stability during use.

[0041] When a tool is used to rotate one of the control knobs 26, one of the mounting rotating rods 24 will be driven to rotate. Under the combined action of the synchronous gear 27 and the annular rack 28, the remaining multiple mounting rotating rods 24 will be driven to rotate synchronously. Furthermore, multiple mounting pressing blocks 25 can be driven to rotate together to fix or release the connecting pipe 13, thus achieving the purpose of facilitating the disassembly and replacement of the connecting pipe 13 and the gas flowmeter 14, and improving the practicability.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
