[0034] The following is a detailed description of the working principle of this gas pipeline sealing detection device.

[0035] like Figure 1-5As shown, when testing the sealing of the gas pipeline, first, the air pump 5 and the stepper motor 91 are connected to the external power supply through a wire, and one end of the gas pipeline is inserted into the corresponding connecting sleeve 43 according to its pipe diameter. The sealing strip 44 on the connecting sleeve 43 is tightly fitted with the inner wall of the gas pipe opening. Then, according to the length of the gas pipeline to be tested, the stepper motor 91 is started, and the output end of the stepper motor 91 drives the lead screw 92 to rotate, so that the connecting plate 94 is moved by the moving block 95. When moving, the slider 96 slides along the outer wall of the guide rod 97 to limit the moving trajectory of the connecting plate 94, thereby moving the moving plate 3 along the moving groove 10. The thrust connects and positions the other end of the gas pipeline, so that the corresponding connecting sleeve 43 on the movable plate 3 is tightly connected to the pipe opening at the other end of the gas pipeline to prevent loosening and leakage when the gas pipeline is pressurized later. After the installation is completed, start the air pump 5, and the output end of the air pump 5 supplies gas to the gas pipeline through the delivery pipe 21. The air is continuously compressed by electricity to generate air pressure, and the air pressure value is checked through the pressure gauge 8. When the pressure reaches the upper line index, the air pump 5 is stopped from continuing to supply gas by closing the solenoid valve 6, and then the air pressure value is observed through the pressure gauge 8 to see if there is any change. If there is a change, it means that the gas pipeline is damaged. If there is no change, it means that the gas pipeline is well sealed.

[0036] The specific types and structures of the solenoid valve 6, air pump 5 and pressure gauge 8 used are all existing products, and the specific circuit connection structure and control relationship of the solenoid valve 6, air pump 5 and stepper motor 91 are all existing technologies, so no further details will be given here.
