Leakage detection equipment for low-pressure natural gas storage tank

The invention provides leakage detection equipment for a low-pressure type natural gas storage tank, and relates to the technical field of low-pressure type natural gas storage tank production. Two to-be-detected low-pressure type natural gas storage tank bodies are placed in the leakage detection unit. A pressurization unit is mounted on the leakage detection unit; a driving unit is mounted on the rear side of the leakage detection unit; a stabilizing unit is mounted on the rear side of the leakage detection unit; the number of the recording units is two, and the two recording units are installed on the leakage detection unit. The number of the arc-shaped recording blocks is two, and the two arc-shaped recording blocks are fixedly installed on output shafts of the two hydraulic cylinders. According to the low-pressure type natural gas storage tank detection device, the detected low-pressure type natural gas storage tank body is marked, and qualified products and unqualified products are prevented from being
