Description

technical field [0001] The invention relates to the technical field of differential pressure power generation, in particular to a differential pressure power generation device capable of connecting multiple sets of series-parallel natural gas pipelines. Background technique [0002] With the current serious situation of environmental protection in our country, the demand for natural gas market is increasing day by day, and the construction speed of natural gas pipeline network is increasing day by day, spreading all over the streets and alleys. [0003] Natural gas pipeline will become the most important way in natural gas transportation. Natural gas pipeline transports natural gas due to pressure difference effect, and natural gas at high pressure flows to low pressure. In order to meet the working pressure of the downstream equipment, decompression treatment is also required. The decompression is generally used to cut off the pressure to waste the differential pressure ene...
