The structure of the air valve is as Figure 1 shown, including an air valve body 100, and an air inlet hole 110 is arranged on the air valve body 100. During specific detection, generally, an air inlet conduit is manually inserted and connected to the air inlet hole 110 on the air valve body 100, and then an external air pump is used in cooperation with the conduit to inject air into the air inlets at both ends of the air valve, and then it is determined whether the air valve leaks. This detection method uses manual alignment, which not only has low work efficiency, but also is prone to inaccurate detection due to inaccurate alignment. Moreover, during the actual air injection test process, the air valve is prone to move, which will also affect the accuracy of the air valve air leakage detection. Therefore, improvement is needed.

[0005] In the above technical solution, during actual work, after aligning the air inlet hole of the air valve with the air nozzle on the base, start the pressing cylinder, the pressing cylinder drives the pressing chuck to press down, presses the air nozzle and the air inlet hole of the air valve firmly, and then an external air pump is used in cooperation with the conduit to ventilate the air nozzle through the air pipe connection hole arranged on the edge of the base, the air nozzle conveys high-pressure gas into the air valve, and it is judged whether the air valve leaks by observing the air valve. After the test is completed, only need the pressing cylinder to drive the pressing chuck to reset, and then separate the air valve from the air nozzle. The test process is simple and convenient.

[0006] Preferably, a cylinder control switch is installed on the top plate on one side of the pressing cylinder, and the cylinder control switch is connected to the pressing cylinder through an air pipe. During actual detection, the opening and closing of the pressing cylinder can be controlled through the cylinder control switch, and the operation is very convenient.

[0007] Preferably, the pressing chuck is arranged in a cylindrical shape. The top of the cylindrical pressing chuck is connected to the telescopic shaft of the pressing cylinder through a thread, and a soft rubber is sleeved at the bottom of the cylindrical pressing chuck. Setting the connection between the pressing chuck and the telescopic shaft of the pressing cylinder as a threaded connection can facilitate the installation and replacement of the pressing chuck. By sleeving a soft rubber at the bottom of the pressing chuck, the protection at the pressing part between the pressing chuck and the air valve can be enhanced, preventing the pressing chuck from damaging the air valve.

[0008] Preferably, two air nozzles are installed vertically upward in parallel and spaced apart below the pressing chuck on the base, and two air pipe connection holes respectively communicating with the two air nozzles are arranged on the edge of the base.

It can realize the automatic positioning docking, pressing, and air injection detection between the air leakage detection component and the air valve, with high working efficiency and good detection effect. During actual work, only need to align the air inlet hole of the air valve with the air nozzle on the base, then start the pressing cylinder. The pressing cylinder drives the pressing chuck to press down, compressing the air nozzle and the air inlet hole of the air valve. Then, an external air pump cooperates with a conduit to ventilate the air nozzle through the air pipe connection hole arranged on the edge of the base. The air nozzle conveys high-pressure gas into the air valve, and it is judged whether the air valve leaks by observing the air valve. After the test is completed, only need the pressing cylinder to drive the pressing chuck to reset, and then separate the air valve from the air nozzle. The test process is simple and convenient.
