ABSTRACT
Gas-liquid linkage valve is a core device in leakage detection system of natural gas trunk pipe, the scientific setting of its parameters directly influences the effectiveness and sensitivity of leakage detection system. A leakage model was firstly build based on gas dynamic theory. finally large amount of numerical calculation analysis Results: The nearer the leakage site was from the starting valve of the pipeline, the more decreasing range the pressure at the starting valve would have. The leakage equivalent diameter had a critical value in the premise of unchanged transmission quantity, pressure and diameter. The established multiple fitting formulas had an average calculation error of less than 10% which had important guiding significance for the diagnosis of pipeline leakage.
