[0001] This utility model relates to the field of pneumatic control valve technology, specifically to an adaptive pneumatic control valve assembly with pressure feedback. Background Technology

[0002] Pneumatic control valves are various pneumatic components used in pneumatic systems to control the pressure, flow rate, and flow direction of airflow, ensuring the normal operation of pneumatic actuators or mechanisms. The structure of a pneumatic control valve can be broken down into two parts: the valve body and the valve core. There are two types: normally closed and normally open.

[0003] Currently, existing pneumatic control valves cannot control the flow rate based on pressure feedback, nor can they control the opening and closing of the pneumatic control valve.

[0004] Therefore, an adaptive pneumatic control valve assembly with pressure feedback is needed to improve the above problems. Summary of the Invention

[0025] As illustrated in Figures 1-3, this utility model provides a technical solution:

[0026] An adaptive pneumatic control valve assembly with pressure feedback includes a valve body 1, a valve plate 2 inside the valve body 1, a connecting cylinder 3 on the top of the valve body 1, a pneumatic chamber 4 on the top of the connecting cylinder 3, movable plates 5 symmetrically arranged on the left and right sides inside the pneumatic chamber 4, springs 6 symmetrically arranged on the upper and lower sides of the movable plates 5, a rack 7 on the inner side of the movable plates 5, a rotating rod 8 on the top of the valve plate 2, toothed grooves 9 evenly opened on the upper side of the outer wall of the rotating rod 8, a pressure sensor 10 installed on the upper side inside the pneumatic chamber 4, an electronic pressure display 11 on the top of the pneumatic chamber 4, a controller 12 on the right side of the electronic pressure display 11, an air inlet pipe 13 in the middle of the front of the pneumatic chamber 4, a solenoid valve 14 installed at the front end of the air inlet pipe 13, a connecting pipe 15 on the right side of the solenoid valve 14, and an air pump 16 on the right side of the connecting pipe 15.

[0027] In this embodiment, the valve plate 2 and valve body 1 are structurally and sized to match, and the valve plate 2 and valve body 1 are connected by a rotatable connection. The upper end of the rotating rod 8 passes through the connecting cylinder 3 and extends into the interior of the pneumatic chamber 4. The rotating rod 8 is also rotatably connected to both the connecting cylinder 3 and the pneumatic chamber 4. The outer diameter of the moving plate 5 is the same as the inner diameter of the pneumatic chamber 4, and the moving plate 5 and pneumatic chamber 4 are connected by a sliding connection. The protruding teeth of the rack 7 are structurally and sized to match the tooth groove 9. The electronic air pressure display 11 is connected to the air pressure sensor 10 and the controller 12 via wires. The controller 12 is connected to the solenoid valve 14 and the air pump 16 via wires. The rotation angle of the valve plate 2 corresponds to the air pressure in the pneumatic chamber 4. Through the air pressure sensor 10, electronic air pressure display 11, controller 12, air inlet pipe 13, solenoid valve 14, connecting pipe 15, and air pump 16, the air pump can stop filling the pneumatic chamber 4 in time after the gas in the pneumatic chamber 4 reaches a certain value, thereby controlling the rotation angle of the valve plate 2 through pressure feedback.

[0028] The working process of this utility model is as follows: In use, the adaptive pneumatic control valve group is initially in the open state. If it needs to be closed, the air pump 16 is started via the controller 12. Gas then enters the pneumatic chamber 4 through the connecting pipe 15, solenoid valve 14, and air inlet pipe 13. Next, the moving plate 5 moves outward and compresses the spring 6. Then, the rack 7 moves along with the moving plate 5, and the protruding teeth of the rack 7 sequentially insert into the tooth grooves 9. Then, the rotating rod 8 rotates, thereby driving the valve plate 2 to rotate. As the air pressure inside the pneumatic chamber 4 increases, the rotation angle of the valve plate 2 also changes. When the air pressure inside the pneumatic chamber 4... When the air pressure reaches a suitable value, the valve plate 2 will rotate to block the valve body 1, and then the solenoid valve 14 and the air pump 16 will close. At this time, the pneumatic control valve group is closed. Through the air pressure sensor 10, electronic air pressure display 11, controller 12, air inlet pipe 13, solenoid valve 14, connecting pipe 15, and air pump 16, the air pump can stop filling the pneumatic chamber 4 in time after the gas in the pneumatic chamber 4 reaches a certain value. Thus, the rotation angle of the valve plate 2 can be controlled by pressure feedback. Based on the above design, the flow rate of the pneumatic control valve group can be intelligently controlled according to the air pressure control method.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
