In view of the current necessity of the road transportation safety of the dangerous goods, the lack of effective emergency blocking technology is the Current issues that need to be focused on. This paper designs a kind of emergency blocking equipment for the leakage of dangerous goods transport vehicle tanks. By introducing a strong magnet and blocking with a rubber layer, the leakage on the surface of the ferromagnetic equipment can be quickly blocked. A simulated test of the designed 1.5 MPa leak stopper was carried out on a vechicle gas cylinder. The test results showed that there was no pressure drop in the gas cylinder during the holding time of 1.5MPa, and the leak plugging effect was better, which can be widely used in maintenance work. In addition, the continuous test found that the leakage limit pressure at the shoulder and bottom of the gas cylinder is lower than that at the cylinder body, and it should be focused on in the subsequent promotion process.
