The invention provides a regional cooling and heating transmission and distribution pipeline network health inspection system, which includes a water separator, a water collector, a water inlet pipeline, a water return pipeline, multiple filters and multiple electric control valves; the water distributor It is connected to multiple terminals through the water inlet pipeline, and the water inlet pipeline includes multiple water diversion ports; the water collector is connected to the terminal through the return water pipeline, and the return water pipeline includes multiple water collection ports; the filter is set in the return water pipeline close to the terminal The collection unit includes a plurality of water pressure sensors, and the connection between the water inlet pipe and the water distributor and the terminal, the water distribution port, the connection between the return water pipe and the water collector and the terminal, and the water collection port are all equipped with water pressure sensors. ; Each filter is located between two water pressure sensors; the electric control valve is set in the water inlet pipeline and the water return pipeline. By arranging a plurality of water pressure sensors in the pipeline, and judging whether there is blockage in the pipeline and the location of the blockage according to the pressure difference detected by the water pressure sensors, real-time monitoring of the pipeline is realized.
