Description

Technical Field

[0001] This utility model relates to the field of oil and gas recovery, specifically to a regulating pneumatic valve for oil and gas recovery. Background Technology

[0002] The regulating pneumatic valve for oil and gas recovery mainly consists of two parts: a pneumatic actuator and a valve body. The pneumatic actuator receives control signals and generates corresponding thrust, changing the position of the valve stem via a push rod or other transmission device to control the opening or closing of the valve. The valve body is the component connected to the pipeline, housing key components such as the valve core and valve seat, ensuring the valve's sealing and fluid control capabilities. In existing technologies, the size of regulating pneumatic valves is fixed, and the positions of the connecting rings on both sides are fixed, making it impossible to adjust the positions of the connecting rings according to installation requirements. This results in poor applicability to different installation environments. Therefore, those skilled in the art have provided a regulating pneumatic valve for oil and gas recovery to solve the problems mentioned in the background art. Utility Model Content

A pneumatic mechanism 2 is installed on the upper end of the valve body 1. A valve is installed inside the valve body 1. Folded tubes 3 are installed at both ends of the valve body 1. A connecting ring 4 is provided on one side of the folded tube 3. Several connecting holes 5 are opened inside the connecting ring 4. A fixing ring 6 is installed at the end of the connecting ring 4 near the valve body 1. Several internally threaded cylinders 7 are rotatably connected inside the fixing ring 6, and the internally threaded cylinders 7 correspond to the positions of the connecting holes 5. Small annular racks 8 are installed on the outer surface of the internally threaded cylinders 7. A rotating ring 9 is rotatably connected to the side of the fixing ring 6. A large annular rack 10 is installed on the inner wall of the rotating ring 9, and the large annular rack 10 meshes with several small annular racks 8. An annular groove 11 is opened on the inner wall of the rotating ring 9. An annular block 12 is slidably connected inside the annular groove 11, and the annular block 12 is fixed to the side of the fixing ring 6. The rotating ring 9 is internally... Several gripping holes 13 are provided. Two telescopic mechanisms 14 are installed on the side of the valve body 1, and the two telescopic mechanisms 14 face opposite directions. The telescopic mechanism 14 is fixedly connected to the fixing ring 6. The telescopic mechanism 14 includes a hollow rod 15 and a sliding rod 18. The hollow rod 15 is fixed to the side of the valve body 1. A sliding groove hole 16 is provided at the upper end of the hollow rod 15. A moving block 17 is slidably connected inside the hollow rod 15. The sliding rod 18 is installed on the side of the moving block 17, and the sliding rod 18 passes through the hollow rod 15 and is fixedly connected to the fixing ring 6. A cavity 19 is provided inside the moving block 17. A pull block 20 is slidably connected inside the cavity 19.

The sliding rod 18 drives the moving block 17 to move in the hollow rod 15. When the moving block 17 moves to the position, the spring 23 pushes the pull block 20 to descend and reset. The pull block 20 drives the positioning block 24 to insert into the corresponding positioning hole 25, fixing the position of the connecting rings 4 on both sides.

[0020] When fixing the valve body 1, the bolt connecting the pipeline is passed through the connecting hole 5 and into one end of the internal threaded cylinder 7.

The annular groove 11 rotates outside the annular block 12. At the same time, the large annular rack 10 and several small annular racks 8 mesh to drive several internal threaded cylinders 7 to rotate. The internal threaded cylinder 7 and the bolt cooperate to screw the bolt into the internal threaded cylinder 7, so that the connecting ring 4 and the pipeline are fixedly connected, thereby installing the valve body 1.
