Embodiment Construction
[0030] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0031] This embodiment provides a device for measuring the initial pressure of vehicle-mounted gas cylinders used in hydrogen refueling stations, see the attached figure 1 , including: hydrogen storage tank 1, hydrogen source pipeline, compressor 2, inlet pneumatic valve 3, outlet pneumatic valve 4, pressure sensor 5, safety valve 6 and hydrogenation gun 7;
[0032] One end of the hydrogen source pipeline communicates with the hydrogen source in the hydrogen long tube trailer or hydrogen refueling station, and the other end communicates with the compressor 2; the compressor 2 is used to compress and boost the hydrogen in the hydrogen source pipeline;
[0033] After the hydrogen storage tank 1 is connected in parallel with the compressor 2, it is connected to the hydrogenation gun 7 through the pipeline A; the hydrogenation gun 7 is used to connect with the...
