The utility model relates to an auxiliary detection device for a natural gas pipeline. The utility model particularly relates to a natural gas pipeline liquid accumulation condition auxiliary judgmentdevice. The pressure tapping device comprises at least two pressure tapping ports which are arranged on the same gas pipeline along the vertical direction, the pressure tapping port is communicated with a gas pipeline; the pressure tapping port is connected with a pressure guide pipe; the pressure guide pipe is connected with a pressure detection mechanism; the method comprises the following steps: detecting and analyzing a pressure difference value between two points at different heights on the same horizontal gas pipeline; the pressure difference value is used for reflecting the pipeline liquid accumulation condition; when the pressure difference value occurs; the occurrence of hydrops can be preliminarily judged; the pressure difference value can be adjusted according to the change condition of the pressure di
