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

[0003] For example, the Chinese utility model patent publication number (CN214146776U) discloses a new type of multifunctional airflow control valve for mechanical and electrical use, which includes a branch pipe and a main pipe. The bottom end of the branch pipe is provided with a main pipe, which is fixed to the branch pipe by welding. The outer periphery of the main pipe is provided with a right flange near the right side, which is fixed to the main pipe by welding.

The top of the branch pipe is provided with a main pipe flange, which is fixed to the branch pipe by welding. An upper flange is provided on the top side of the main pipe flange, which is fixed to the main pipe flange by fixing nuts and fixing bolts. An outer pipe is provided at the upper end of the upper flange, which is fixed to the upper flange by welding.

When the plug rod 804 enters the slot 808, the inner wall of the slot 808 squeezes the second block 807, so that the second block 807 enters the second installation groove 805. At the same time, the third spring 806 is compressed. When the second block 807 moves to the second clamping hole 809, the third spring 806 bounces the second block 807 into the second clamping hole 809, so that the plug rod 804 is connected to the connecting rod 6. At this time, turn the handle 803, the handle 803 drives the plug rod 804 to rotate, and the plug rod 804 drives the connecting rod 6 to rotate, thereby driving the threaded rod 712 to rotate, and the height of the adjustment block 713 can also be adjusted.
