CNG (compressed natural gas) pressure reduction pry

The utility model provides a compressed natural gas (CNG) decompression pry which comprises a storage tank, a first gas outlet pipeline and a main gas outlet pipeline, an outlet of the first gas outlet pipeline is communicated with an inlet of the main gas outlet pipeline through at least two decompression pipelines which are connected in parallel, and each decompression pipeline comprises a pressure regulating valve and a second gas outlet pipeline which are communicated in sequence. The pipe diameter of the second air outlet pipeline and the total air outlet pipeline is larger than that of the first air outlet pipeline. According to the CNG pressure reduction pry, high-pressure natural gas in the storage tank is subjected to flow division and pressure reduction through the two pressure reduction pipelines connected in parallel, the pressure regulating valve is arranged on each pressure reduction pipeline, pressure reduction output of the natural gas in each pressure reduction pipeline is achieved, and meanw
