It can be divided into high-pressure gas tanks, low-pressure gas tanks, and normal-pressure gas tanks according to the pressure it can withstand. Gas tanks are prone to internal gas leakage after long-term use. For example, if explosive gas is filled inside, leakage will directly lead to a large explosion and cause harm to people. Therefore, it is necessary to install a sealing detection device on the gas tank to detect the sealing of the gas tank.

[0003] According to a Chinese patent with publication number CN217687704U, a sealing detection device based on a gas tank is disclosed.
