[0023] like Figures 1-4 As shown, this utility model provides a technical solution:

[0024] An intelligent industrial testing vacuum device includes a vacuum chamber 1, a door 17 movably disposed on the outer side of the middle part of the vacuum chamber 1, a hanger 2 disposed on the upper part of the interior of the vacuum chamber 1, a clamping mechanism disposed on both sides of the hanger 2, the clamping mechanism including a sleeve 8, the sleeves 8 are symmetrically disposed on both sides of the upper part of the interior of the vacuum chamber 1, a piston rod 9 movably connected to the sleeve 8 is disposed at the top of both sides of the hanger 2, a spring 10 is disposed between the piston rod 9 and the interior of the sleeve 8, the other end of the switching valve 1 5 is connected to a diversion pipe 11, the end of the diversion pipe 11 away from the switching valve 1 5 is connected to the upper end of the sleeve 8, and a positioning pin 18 is disposed at both ends of the same side of the mounting plate 1 14 and the mounting plate 2 6.

[0025] In this embodiment, the clamping mechanism consisting of air pump 4, switching valve, sleeve 8, piston rod 9 and spring 10 can achieve stable clamping of industrial pipelines. During the inspection process, the pipeline is firmly fixed, avoiding inaccurate test results due to pipeline shaking or displacement. When air pump 4 sends air to the diversion pipe 11 and compresses it into sleeve 8, piston rod 9 can move downward smoothly, driving hanger 2 to lower mounting plate 6. With the help of positioning pin 18 on mounting plate 14, the pipeline is accurately fixed in the designated position, providing a stable foundation for subsequent inspection. Moreover, it can be used for pipelines of different lengths.

[0026] like Figure 3 and Figure 4As shown, a vacuum pumping mechanism is provided at the bottom of the vacuum chamber 1. The vacuum pumping mechanism includes a vacuum pump 12. The vacuum pump 12 is located at the bottom of the vacuum chamber 1. The inlet end of the vacuum pump 12 passes through the vacuum chamber 1 and is fixedly installed with a switching valve 13. The upper end of the switching valve 13 is connected to a mounting plate 14. An electric valve 15 is provided between the bellows 7 and the mounting plate 16. A pressure sensor 16 is provided on the inner side of the back of the vacuum chamber 1. An air intake mechanism is provided at the top of the vacuum chamber 1. The air intake mechanism includes a top shell 3. The top shell 3 is located at the middle of the top of the vacuum chamber 1. An air pump 4 is located at the top of the vacuum chamber 1 and inside the top shell 3. A switching valve 5 is located at the outlet end of the air pump 4 and inside the vacuum chamber 1. The mounting plate 16 is connected to the lower middle part of the hanger 2. The bottom end of the switching valve 15 is connected to the bellows 7. The top end of the mounting plate 16 passes through the hanger 2 and is connected to the bellows 7.

[0027] In this embodiment, a pressure sensor 16 is installed inside the device. When gas is injected into the pipeline, if there is a leak in the pipeline, the pressure sensor 16 can detect the pressure change in a timely and sensitive manner. The above detection method can accurately determine whether there is a leak in the pipeline, effectively avoid missed detection or false detection, and improve the accuracy and reliability of industrial detection.

[0028] Working principle: When industrial pipelines need to be inspected, the flange at the bottom of the pipeline is fitted onto mounting plate 14, and the bolt hole is engaged with the positioning pin 18. Then, the air pump 4 is started, which sends external air to the distribution pipe 11 and compresses it into the sleeve 8, causing the piston rod 9 to move downward. When the piston rod 9 moves, it drives the hanger 2 to lower the mounting plate 6. When the mounting plate 6 lowers, the positioning pin 18 on it is inserted into the bolt hole on the upper flange of the pipeline, thereby clamping the pipeline through the mounting plate 6 and mounting plate 14. Then, the chamber door 17 is closed, and the vacuum pump 12 is started. After the vacuum pump 12 starts, the air inside the vacuum chamber 1 is extracted through the switching valve 13 to create a negative pressure state. Then, the switching valve 13 is closed, and the switching valve 5 is started. External gas is pumped into the bellows 7 through the air pump 4 and then poured into the pipeline through the mounting plate 6. If there is a leak in the pipeline, the pressure sensor 16 will detect it.
