Current limiter used for controlling pressure regulator signals

The utility model belongs to the technical field of fuel gas transportation and distribution equipment, and discloses a current limiter used for controlling the pressure regulator signals. The current limiter has the main technical characteristics that the current limiter comprises a housing with an air inlet and at least one air outlet; a cylindrical adjusting plug cock with a retaining screw is arranged in the air inlet; and a V-shaped eccentric groove is formed in the position where the adjusting plug cock is matched with the air inlet. Through the adoption of the structure that the sectional area of the V-shaped eccentric groove can be different by rotating the adjusting plug cock, so that the amount of flue gas going through is different, the current limiter used for controlling the pressure regulator signals, provided by the utility model, has the advantages that the fuel gas amount can be changed by rotating the adjusting plug cock to achieve the purpose of limiting the through-put amount; if no V-shap
