The intelligent pressure regulating valve for bottled liquefied gas according to claim 5, characterized in that: If, in comparison result three, the comparison between the total target pressure value and the optimized value of the sub-target pressure is not within the preset error threshold, then preset the optimized values ​​of the inlet pressure, the optimized value of the regulating chamber pressure, and the optimized value of the outlet pressure. Then, according to the step-by-step comparison method, the optimized value of the inlet pressure is compared with the target pressure value of the inlet, the optimized value of the regulating chamber pressure is compared with the target pressure value of the regulating chamber, and the optimized value of the outlet pressure is compared with the target pressure value of the outlet, thereby generating damage points located at the inlet, regulating chamber, and outlet of the pressure regulating valve.

7. The intelligent pressure regulating valve for bottled liquefied gas according to claim 6, characterized in that: The data processing module includes a damage confirmation unit and an adjustment unit. The damage confirmation unit is used to acquire the damage points in comparison result one, comparison result two, and comparison result three, and generate the damage point result of the pressure regulating valve body based on the consistency of the damage points in comparison result one, comparison result two, and comparison result three. The adjustment unit is used to generate a control command based on the damage point result of the pressure regulating valve body and transmit it to the pressure regulating valve body. The pressure regulating valve body also includes a control unit, which receives the control command and controls the cut-off mechanism to cut off the liquefied gas transmission of the pressure regulating valve body.
