[0031] The clamping assembly, located on the outer surface of the mounting base 3, is used to drive the two clamping blocks 7 to clamp the natural gas connection pipe 2;

[0032] The detection component, located on the outer surface of the mounting base 3, is used to detect the pressure of the natural gas ball valve body 1. The two clamping blocks 7 move towards each other to clamp and fix the natural gas connecting pipe 2.

[0033] Furthermore, the clamping assembly includes a connecting block 10 and a connecting rod 13. The connecting block 10 is rotatably connected inside the mounting base 3. The connecting block 10 has a U-shaped structure. The connecting rods 13 are rotatably connected to both sides of the connecting block 10. The two connecting rods 13 are rotatably connected to the corresponding clamping blocks 7. The two clamping blocks 7 are rotatably connected to the inside of the mounting base 3. The moving column 12 at the bottom of the adapter block 11 moves inside the connecting block 10. Since the connecting block 10 has a U-shaped structure and is rotatably connected to the inside of the mounting base 3, the movement of the moving column 12 will drive the connecting block 10 to rotate. The rotation of the connecting block 10 is transmitted to the clamping blocks 7 through the connecting rods 13.

[0034] Furthermore, a push block 6 is rotatably connected to the outer surface of the mounting base 3, and a push cylinder 5 is fixedly installed at the bottom of the mounting base 3. The output end of the push cylinder 5 is fixedly connected to the bottom of the push block 6. A transition block 11 is rotatably connected inside the mounting base 3. The transition block 11 is rotatably connected to the push block 6. A moving column 12 is fixedly connected to the bottom of the transition block 11. The moving column 12 is located inside the connecting block 10. The output end of the push cylinder 5 pushes the push block 6 to rotate on the outer surface of the mounting base 3. The rotation of the push block 6 causes the transition block 11, which is rotatably connected to it, to move.

[0035] Furthermore, the top of the mounting base 3 is designed with an arc shape to fit against the natural gas connection pipe 2.

[0036] Furthermore, the detection components include a PLC controller 4, detection blocks 8, and pressure sensors 9. Detection blocks 8 are fixedly connected to the outer surfaces of the two clamping blocks 7 that are close to the natural gas ball valve body 1. Both detection blocks 8 are arranged in an arc shape, and pressure sensors 9 are fixedly installed on the outer surfaces of both detection blocks 8. The PLC controller 4 is fixedly installed on the outer surface of the mounting base 3. The detection blocks 8 fixed to the outer surfaces of the two clamping blocks 7 are also close to the natural gas ball valve body 1. The detection blocks 8 are arc-shaped, which can better fit the outer surface of the natural gas ball valve body 1. Pressure sensors 9 are installed on the outer surfaces of the detection blocks 8 to detect the pressure on the natural gas ball valve body 1 during the test.

[0037] Furthermore, slots 14 are provided on the outer surfaces of the two detection blocks 8 that are close to the natural gas ball valve body 1.

The PLC controller 4 will receive the data from the two pressure sensors 9 through wireless connection and monitor the performance of the natural gas ball valve body 1 under different pressure conditions in real time.

[0039] Working Principle: When the operator needs to use this ball valve pressure detection device to test the pressure of the natural gas ball valve body 1, firstly, the push cylinder 5 is activated. The output end of the push cylinder 5 pushes the push block 6 to rotate on the outer surface of the mounting base 3. The rotation of the push block 6 drives the movement of the rotating block 11 connected to it. The moving column 12 at the bottom of the rotating block 11 then moves inside the connecting block 10. Since the connecting block 10 has a U-shaped structure and is rotatably connected to the inside of the mounting base 3, the movement of the moving column 12 will drive the connecting block 10 to rotate. The rotation of the connecting block 10 is transmitted to the clamping block 7 through the connecting rod 13, causing the two clamping blocks 7 to move towards each other, thereby clamping and fixing the natural gas connecting pipe 2. While the clamping blocks 7 are clamping the natural gas connecting pipe 2, the detection blocks 8 fixed on the outer surface of the two clamping blocks 7 will also approach the natural gas ball valve body 1. The detection blocks 8 have an arc-shaped structure, which can better... The outer surface of the natural gas ball valve body 1 is fitted with a pressure sensor 9, which is installed on the outer surface of the detection block 8 to detect the pressure on the natural gas ball valve body 1 during the test. The PLC controller 4, as the control center of the entire device, controls the push cylinder 5 to complete the clamping action and then starts the pressure detection process. The PLC controller 4 receives data from the two pressure sensors 9 through a wireless connection and monitors the performance of the natural gas ball valve body 1 under different pressure conditions in real time. The slot 14 opened on the outer surface of the detection block 8 close to the natural gas ball valve body 1 can be used to contain the test medium for more accurate pressure measurement. After collecting the data from the pressure sensors 9, the PLC controller 4 processes and analyzes the data to determine whether the natural gas ball valve body 1 meets the predetermined pressure standard. After the test is completed, the PLC controller 4 can output the test result, indicating whether the natural gas ball valve body 1 has passed the test.
