The invention provides a two-stage pilot pressure reducer. The pressure reducer comprises a valve body, a first-stage pressure reducer and a second-stage pressure reducer are arranged in the valve body, an outlet channel of the first-stage pressure reducer is an inlet channel of the second-stage pressure reducer, an inlet connection-line nozzle, a first-stage outlet connection-line nozzle and a second-stage outlet connection-line nozzle are arranged on the valve body, the inlet connection-line nozzle is used for feeding high-pressure gas into the first-stage pressure reducer, and the first-stage outlet connection-line nozzle and the second-stage outlet connection-line nozzle are used for outputting two stages of different pressures of gas after pressure reduction. According to the two-stage pilot pressure reducer, the first-stage pressure reducer and the second-stage pressure reducer are arranged in the same valve body, the outlet channel of the first-stage pressure reducer is the inlet channel of the second-
