The piston-type pressure difference kinetic energy drive device includes at least two piston-type cylinders, and the piston-type cylinder is divided into an upper chamber and a lower chamber by a piston. The upper chambers are respectively connected to the high-pressure natural gas inlet pipeline, and the lower chambers are connected to the low-pressure natural gas outlet pipeline; the main line regulating valve and the piston-type pressure difference kinetic energy drive device are connected in parallel between the high-pressure natural gas inlet pipeline and the low-pressure natural gas outlet pipeline. Compared with the prior art, the utility model adopts a piston and a crank-connecting rod transmission device to convert the pressure energy of natural gas into kinetic energy, and drives the generator to rotate to achieve the purpose of power generation, thereby realizing the energy recovery of high-pressure natural gas, with a simple and reasonable structure, a small volume, and easy operation and maintenance. However, the patent has the following shortcomings: when the device is used, the device has no limiting mechanism, and the connecting pipe is not convenient to be limited, which may cause the high-pressure natural gas intake pipeline and the connecting pipe on the device to slip, and when the solenoid valve controller on the device is used for a long time, the device has no heat dissipation mechanism, and the internal part of the solenoid valve controller on the device is not convenient to be cooled, which may reduce the service life of the solenoid valve controller on the device.
