Regulating device is the core equipment in urban gas pipeline network system. In courtyard gas supply engineering design

the scheme selection of gas pressure regulating determines the economy of investment operation and reliability of supply safety throughout the total network life cycle. Firstly

the current commonly used pressure regulating schemes in gas supply enterprises are introduced briefly

respectively namely

building regulating

regional regulating and household regulating

and their technical characteristics are analyzed. Then

taking a courtyard gas supply engineering design in Qingdao Jimo as an example

the economic comparison are obtained for above-mentioned three kinds schemes. Finally

some suggestions are considered for selecting of pressure regulating scheme in the courtyard gas supply.
