Description

Technical Field

[0001] The utility model relates to the technical field of natural gas pipeline valve maintenance, in particular to an underground gas pipeline valve maintenance auxiliary device. Background Art

[0002] Underground gas pipeline valves are an important part of the gas transmission and distribution system.
