Research On The City Gas Medium To Low Pressure Regulating Installation Risk Analysis And Methods Of Technological Improvement

Gas Medium to Low Pressure Regulating Installation is a high pressure on the upper reaches of the gas pressure reduction,to provide a stable setting pressure of the downstream gas pressure regulator,is one of the important safety control equipment in the gas transmission and distribution system.In the low pressure in the tank because of its gas network terminal,densely distributed in the residential area,is the priority among priorities of the safe operation of equipment,once the low pressure tank malfunction,will lead to gas leakage,the user end gas instability and a series of problems,and there may be security risks,causing injuries and property losses.Based on the investigation of active towns in the low pressure tank equipment operation,through the fault tree analysis method,establish a reasonable and quantitative regulator tank potential risk identification,analysis and evaluation model,and based on the model,the problem of determining the pressure regulating tank is hidden levels,puts forward the retrofit scheme of relative should the operable and efficient.
