1.corecomponent
Gas topPressure device：usuallyUsing nitrogengas cylinderGroup（high pressureinertiaGas),By reducing pressureValve controlAir pressure,maintainpipeline networkpressure
fire water tank（18m³）：Storage fire protection用水，materialoptionalstainless steel/carbon steelanticorrosive,needCompliant with GB50974 standard.
atmospheric pressurewatercan: Bufferpressure fluctuation, volumeneedaccording to the systempressurecurveCalculate（suggestion1 2m³）。
