When the medium viscosity is low or the flow rate is high, the cross-sectional area of ​​the inlet flow channel of the connecting pipe is increased to reduce the flow resistance and further optimize the discharge state of the medium. This variable cross-section flow channel valve body can significantly improve the adaptability of the valve to different media and working conditions. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below.

[0022] In order to solve the problems existing in the background art, this application proposes the following technical solution: a quick-release dual rotor metering valve, including at least two valve bodies 4, a convex ring 19 fixedly connected to the outside of the valve body 4, and a quick-release assembly provided on the outside of the valve body 4, and the valve body 4 can be detachably fixedly connected through the quick-release assembly.

[0023] The quick-release assembly consists of clamps 2 on both sides of the valve body 4. The first fixing bracket 3 and the second fixing bracket 7 are externally fixedly connected to a connecting rod 6. The clamps 2 are rotatably connected to the connecting rod 6. One end of one clamp 2 is rotatably connected to a threaded rod 9. The other clamp 2 has a locking slot at the position corresponding to the threaded rod 9. The threaded rod 9 is externally threaded with a nut 10. The clamp 2 is placed on the outside of the valve body 4, the threaded rod 9 is rotated to lock into the locking slot, and the clamp 2 can be locked and fixed by rotating the nut 10.

[0024] In this embodiment, a large rotor 5 is rotatably connected inside the valve body 4. The large rotor 5 has a through hole, and a rotating column 22 is rotatably connected inside the through hole. Multiple small rotors 21 are fixedly connected to the outside of the rotating column 22. A first fixed frame 3 and a second fixed frame 7 are fixedly connected to the outside of the valve body 4. A 180° actuator 1 is fixedly connected to the outside of the first fixed frame 3, and a 90° actuator 8 is fixedly connected to the outside of the second fixed frame 7. The 90° actuator 8 is used to drive the large rotor 5 to rotate, and the 180° actuator 1 is used to drive the rotating column 22 to rotate. In the specific design, the output end of the 180° actuator 1 is fixedly connected to a first rotating shaft. The first rotating shaft passes through the large rotor 5 and is fixedly connected to the rotating column 22. The output end of the 90° actuator 8 is fixedly connected to a second rotating shaft, and the output end of the second rotating shaft is fixedly connected to the outside of the large rotor 5.

[0025] The above technical solution is explained as follows: The large rotor 5 starts to rotate under the drive of the 90° actuator 8. As the large rotor 5 rotates, the material filled in the valve body 4 is brought to the vicinity of the lower discharge port. During this process, the opening and closing of the large rotor 5 mainly plays the role of initially controlling the material flow rate and realizing the coarse metering of the material. After the material is initially metered by the large rotor 5, the small rotor 21 is further controlled by the 180° actuator 1 for precise metering. The rotation speed of the small rotor 21 can usually be adjusted more finely according to actual needs. Through the coordinated cooperation with the large rotor 5, the material is more accurately distributed and metered, thereby improving the metering accuracy of the entire metering valve.

[0026] In addition, to avoid rigid friction, a rubber ring 20 is fixedly connected to the outer edge of the large rotor 5.

[0027] In order to regulate the flow rate entering the valve body 4, a flow regulation component is also provided on the outside of the valve body 4.

[0028] The system comprises a connecting pipe 11 fixedly connected to the outside of the valve body 4, and a flow regulating component consisting of multiple annular airbags 12 connected within the connecting pipe 11. Each annular airbag 12 is fixedly connected to an air tube 13. One end of each air tube 13 extends to the outside of the connecting pipe 11 and is fixedly connected to a delivery pipe 14. An input pipe 15 is fixedly connected to the outside of the delivery pipe 14, and a solenoid valve 16 is fixedly connected to the input pipe 15. An elastic sleeve 17 is fixedly connected to the outside of the annular airbag 12, and multiple buffer columns 18 are fixedly connected to the inner wall of the elastic sleeve 17. The input pipe 15 is connected to an air pump, which delivers gas to regulate the flow of the annular airbags. The annular airbag 12 expands, and at the same time, the annular airbag 12 compresses the elastic sleeve 17, which reduces the diameter inside the connecting pipe 11. The buffer columns 18 also move closer to each other, thereby reducing the inner diameter of the connecting pipe 11. When the medium viscosity is high or the flow rate is low, the inlet flow channel cross-section of the connecting pipe 11 is reduced to increase the flow rate of the medium, enhance its flushing ability, and prevent the medium from depositing at the inlet. When the medium viscosity is low or the flow rate is high, the inlet flow channel cross-section of the connecting pipe 11 is increased to reduce the flow resistance and further optimize the discharge state of the medium. When the solenoid valve 16 is opened to release the gas, the gas can be discharged to the outside through the input pipe 15.

[0029] The usage method of this embodiment is as follows:

[0030] The large rotor 5 starts to rotate under the drive of the 90° actuator 8. As the large rotor 5 rotates, the material filled in the valve body 4 is brought to the vicinity of the lower discharge port. During this process, the opening and closing of the large rotor 5 mainly plays the role of initially controlling the material flow rate and realizing the coarse metering of the material.

[0031] After the material is initially metered by the large rotor 5, the small rotor 21 is further controlled by the 180° actuator 1 for precise metering. The rotation speed of the small rotor 21 can usually be adjusted more precisely according to actual needs. Through its cooperation with the large rotor 5, the material is more accurately distributed and metered, thereby improving the metering accuracy of the entire metering valve.

[0032] If it is necessary to adjust the flow rate into the valve body 4, simply connect the input pipe 15 to the air pump, and the air pump will deliver gas to expand the annular airbag 12. At the same time, the annular airbag 12 will squeeze the elastic sleeve 17, which will reduce the diameter of the connecting pipe 11. The buffer columns 18 will also move closer to each other, thereby reducing the inner diameter of the connecting pipe 11.

[0033] Therefore, by adopting a variable cross-section design within the connecting pipe 11, the cross-sectional area of ​​the inlet flow channel can be adjusted in real time according to the characteristics of the medium and the flow requirements. When the medium viscosity is high or the flow rate is low, the cross-section of the inlet flow channel of the connecting pipe 11 is reduced to increase the medium velocity, enhance its flushing ability, and prevent the medium from depositing at the inlet. When the medium viscosity is low or the flow rate is high, the cross-section of the inlet flow channel of the connecting pipe 11 is increased to reduce the flow resistance and further optimize the discharge state of the medium. This variable cross-section flow channel valve body 4 can significantly improve the valve's adaptability to different media and operating conditions.
