This utility model relates to the technical field of natural gas vehicle-mounted gas supply systems, specifically disclosing an integrated pressure reducing and regulating device and a natural gas vehicle-mounted gas supply system. The integrated pressure reducing and regulating device includes a regulating device body, a solenoid valve assembly, and a filter assembly. The regulating device body has an inlet and an outlet connected sequentially. By using this integrated pressure reducing and regulating device, the solenoid valve assembly and the filter assembly are integrated into the regulating device body, effectively reducing the number of joints in the pipeline connections within the natural gas vehicle-mounted gas supply system, thereby reducing the risk of leakage. This effectively solves the problem in the prior art where the solenoid valve, filter, and regulating device are independent components, which easily leads to leakage during installation and affects the safety of the natural gas vehicle-mounted gas supply system. Simultaneously, it not only improves the overall stability and reliability of the natural gas vehicle-mounted gas supply system but also provides a feasible basis for the modular integration of natural gas vehicle-mounted gas supply systems.
