Abstract
The invention provides a two-stage safe fuel gas pressure stabilizer. The two-stage safe fuel gas pressure stabilizer is formed by improving an exiting intermediate-low-price pressure stabilizer. The two-stage safe fuel gas pressure stabilizer is characterized in that a sliding type valve block is arranged at a proper position of a gas inlet channel and aligned with a valve seat in a matched mode, a first-level pressure adjustment elastic valve element is arranged below a first-level pressure adjustment nozzle and is aligned with the first-level pressure adjustment nozzle, a second-level pressure adjustment elastic valve element is arranged below a second-level pressure adjustment nozzle, the work travel of the second-level pressure adjustment elastic valve element is larger than that of the first-level pressure adjustment elastic valve element, and a valve element ejector rod in the second-level pressure adjustment elastic valve element is fixedly connected with a pressure adjustment pull rod. By the adoption of the two-stage safe fuel gas pressure stabilizer, when a valve body ages and pressure adjustment is ineffective, fuel gas can be automatically closed, and it is determined that a user can use the fuel gas most safely; when various air leakage conditions with the flow larger than a set use flow occur, the fuel gas is automatically closed, and safety is guaranteed.
