The invention relates to the field of gas supply including operation safety of gas consuming devices predominantly of communal household purpose (gas stoves, instantaneous water heaters, housing heaters for low gaseous pressure, etc.) and designed for protection against uncontrolled gas pressure boost in the supply net and gas consuming devices. The presented method comprising a supply system of gas of certain pressure is characterized in that a safety shutdown valve 3 joint with a pressure sensor 2 adjusted for system outlet extreme pressure is further mounted at the inlet to the gas supply system 1, and a junction point 4 of branch pipelines at the angle of 90 to135° and one to three successive pivotal points 7 at the angle of 90 to 135° for the branch gas pipeline 11 directed to the low pressure gas supply net are arranged at the straight-line portion of the gas pipeline beside the safety shutdown valve, and a burst valve 5 rated for yield value of acceptable gas pressure and an outlet 6 for release of gas into the atmosphere are further mounted at the junction point 4 immediately behind the branch gas pipeline, wherein the mounted burst valve is equipped with the damage alert system 12 to transmit a signal to the gas supply operator's desk. |
