FIELD: gas industry.
SUBSTANCE: invention relates to gas supply and can be used in the structure of gas distribution stations (GDS) and gas regulating stations (GRS) to reduce the pressure of natural gas from the associated utilization of the energy of the gas stream in order to increase the autonomy and reliability of the GDS and GRS.
EFFECT: technical result is the possibility of reducing the pressure of natural gas and maintaining it at a given level at reduction points with relatively low costs and pressures with the associated utilization of the energy of the gas flow, regardless of external influences affecting the parameters of the gas flow, without the use of a pressure regulator as a separate device and without an individual system for stabilizing the rotational speed of the expander.
