Moreover, in extreme weather, the gas system needs to be temporarily controlled according to rescue needs. The existing gas pipeline system structure is too complex. Often, when a situation occurs, water and electricity need to be cut off in a large area, resulting in unnecessary expansion of the impact and not being able to well meet the rescue needs.

[0003] Therefore, there is an urgent need in the market for a topological structure of a gas system that is simple in structure and can flexibly respond to extreme weather. Summary of the Utility Model
