[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1-3 As shown, the interactive pneumatic valve includes a rotary cylinder 1, which comprises a cylinder body 10, an output shaft 11, an air inlet 12, and an exhaust port 16. The rotary cylinder 1 is existing technology; the specific internal structure of the cylinder body 10 is not shown. Different models of rotary cylinder 1 can achieve different angle adjustments. The output shaft 11 is fixedly connected to the cylinder body 10. A pair of air inlets 12 are fixedly arranged on one side of the cylinder body 10, and an exhaust port 16 is fixedly arranged on the other side. A piston is installed inside the cylinder body 10, and the piston is connected to the output shaft 11. The linear motion of the piston is converted into the rotational motion of the output shaft 11 through a mechanical structure. Port 12 is used to connect to an external compressed air source. One air inlet 12 is used to control the forward rotation of the output shaft 11, and the other air inlet 12 is used to control the reverse rotation of the output shaft 11. External compressed air enters the cylinder body 10 through the air inlet 12, pushing the piston to move and realize the rotation of the output shaft 11, which drives the cylinder body 10 to rotate synchronously. After completing one rotation, the piston movement ends, and the compressed gas in the cylinder is released through the exhaust port 16. At this time, the air pressure inside the cylinder decreases. An exhaust filter 9 is fixedly installed on the exhaust port 16 to mitigate the impact of the gas being sprayed out instantaneously through the exhaust port 16.

[0021] In one embodiment of this invention, a mounting plate 2 is rotatably mounted on the rotary cylinder 1. A valve body 4 is mounted on the mounting plate 2. A pair of support components 3 are symmetrically arranged on the mounting plate 2. One end of each support component 3 is fixedly connected to the mounting plate 2, and the other end is fixedly connected to the valve body 4. A pipe 6 is provided on the inner ring of the valve body 4. An adjusting shaft 7 is rotatably mounted inside the valve body 4. One end of the adjusting shaft 7 passes through the mounting plate 2 and is fixedly connected to the output shaft 11. The other end passes through the valve body 4 and is fixedly connected to a pointer 17. A sealing gasket is provided at the connection between the adjusting shaft 7 and the pipe 6 to prevent fluid from overflowing from the pipe 6. A scale 5 is fixedly installed on the top, and scale lines 18 are set inside the scale 5. A pointer 17 is rotated inside the scale 5. A valve disc 8 is fixedly installed on the adjusting shaft 7. The valve disc 8 is set inside the pipeline 6, and the inner diameter of the valve disc 8 is the same as that of the pipeline 6. When the rotary cylinder 1 is started, it drives the adjusting shaft 7 to rotate, thereby realizing the rotation of the valve disc 8. The flow rate in the pipeline 6 is adjusted by the rotation of the valve disc 8. The rotation of the adjusting shaft 7 also drives the pointer 17 to rotate. The rotation angle of the pointer 17 is observed through the scale 5, that is, the opening and closing angle of the valve disc 8 is observed, which makes it convenient for maintenance personnel to observe whether the rotary cylinder 1 is operating normally.

[0022] As one embodiment of this invention, the support component 3 includes a support block 14 and a limiting shaft 13. The support component 3 is provided in pairs, with the limiting shaft 13 fixedly connected to the support block 14. The mounting plate 2 has several limiting holes 15. In this embodiment, the limiting shaft 13 is a threaded rod, and the limiting hole 15 is a threaded hole. By screwing the limiting shaft 13 into the limiting hole 15, the support component 3 is fixedly connected to the mounting plate 2. When in use, the device can be integrated and controlled by a PLC control system. The switching of the air inlet 12 can be achieved through the control terminal, that is, the adjustment of the opening and closing angle of the valve disc 8.

[0023] Working principle:

[0024] In use, first install the valve body 4 on the pipeline 6, rotate the mounting plate 2 on the rotary cylinder 1, and fix a pair of support components 3 on the mounting plate 2. Then, pass the adjusting shaft 7 through the mounting plate 2 and fix it to the output shaft 11. Then, fix the valve body 4 to the support components 3. Fix the exhaust filter on the exhaust port 16, and fix the air inlet 12 to the interface of the external compressed air source. External compressed air enters the cylinder body 10 through the air inlet 12, pushing the piston in the cylinder body 10 to move and realize the rotation of the output shaft 11; thereby realizing the rotation of the valve disc 8. After completing one rotation adjustment, the piston movement ends, and the compressed gas in the cylinder body 10 will be released through the exhaust port 16. At this time, the air pressure inside the cylinder decreases, making it convenient to realize the next adjustment. The rotation of the valve disc 8 also drives the pointer 17 to rotate. The rotation angle of the pointer 17 is observed through the scale 5, that is, the opening and closing angle of the valve disc 8 is observed.
