Description

Technical Field

[0001] The utility model relates to the field of water tank leakage elimination, in particular to a water tank leakage elimination device with a double sealing structure. Background Art

[0002] When a water tank leaks, chemical reactions or physical damage will occur at the leaking point and the surrounding area of ​​the tank. If effective protective measures are not taken for the area around the leaking point and welding is directly performed, even if the leak is successfully eliminated, leakage will occur later. Electric welding or plastic welding is difficult to operate, and the high temperature released during the operation will also cause secondary damage to the tank. If the welding operation cannot eliminate the leak, the welding slag left on the tank cannot be completely processed, which will affect the subsequent leakage elimination operation.
