Initially, the preliminary positioning is completed by the magnetic attraction of the magnet 3, and then the battery and control button 7 for controlling the magnetism of the iron core are started to make the coil iron core magnetic. At this time, the electromagnet 2 further completes the adsorption and positioning of the chlorine cylinder body, and the magnetic plugging components magnet 3 and electromagnet 2 form the first plugging isolation layer with the liquid chlorine cylinder; ③ Preliminarily combine the elastic sealing member 19 of the sealing cover with the liquid chlorine cylinder, and then press the pressure rod downward to form a certain degree of vacuum in the lower cavity of the piston, lock the pressure rod to prevent the vacuum from being destroyed, and finally complete the vacuuming step in the same way to finally form the second plugging isolation layer; ④ Connect the quick connector 9 to allow the chlorine gas overflowing from the plugging device to enter the titanium storage tank through the dedicated pipeline 10. Chlorine gas reacts with sodium hydroxide solution to produce sodium hypochlorite solutions of different concentrations. ⑤ If the surface of the liquid chlorine cylinder is relatively rough and it is difficult to form a vacuum, the retractable guide rod 27 can be connected to the sealing cover with the help of auxiliary fixing components, and then the guide rod 30 with a hook passes through the fixing component 29 with a positioning hole, hooks the retaining rings at both ends of the liquid chlorine cylinder, and tightens the locking hand wheel 28 to further fix the leak-proof device. In this way, the leakage and recovery problems of the liquid chlorine cylinder are quickly and effectively solved.

[0051] The detailed working process of the cylinder body leaking during transportation is as follows: ① firstly combine the magnetic plugging component (magnet 3 and electromagnet 2) with the leaking part of the liquid chlorine cylinder, start the switch to make the coil core generate magnetism, at this time, the magnetic plugging component and the liquid chlorine cylinder form the first plugging isolation layer; ② preliminarily combine the elastic seal of the cover with the liquid chlorine cylinder, then rotate the vacuum hand wheel diagonally to form a certain degree of vacuum in the lower cavity of the piston, lock the guide rod nut to prevent the vacuum from being destroyed, and finally complete the vacuum step in the same way to finally form the second plugging isolation layer; ③ connect the telescopic guide rod 27 to the cover, then pass the guide rod 30 with a hook through the fixing assembly 29 with a positioning hole, hook the retaining rings at both ends of the liquid chlorine cylinder, and tighten the locking hand wheel 28 to further fix the plugging device. In this way, the leakage problem of the liquid chlorine cylinder is quickly and effectively solved.

[0052] Detailed working process of bottle valve or fusible plug leakage: ① first remove the magnetic plugging components (magnet 3 and electromagnet 2); ② seal the elastic seal of the cover with the periphery of the bottle valve (fusible plug), then rotate the vacuum hand wheel diagonally to form a certain degree of vacuum in the lower cavity of the piston, lock the guide rod nut to prevent the vacuum from being destroyed, and finally complete the vacuum step in the same way; ③ connect the retractable guide rod 27 to the cover, then pass the guide rod 30 with a hook through the fixing assembly 29 with a positioning hole, hook the hole on the retaining ring of the liquid chlorine cylinder, and tighten the locking hand wheel 28 to further fix the plugging device. In this way, the leakage problem of the liquid chlorine cylinder is quickly and effectively solved.
