Abstract：Aiming at the practical difficult problem of pipeline explosion-proof valves being easy to be mis-operated in engineering application,a simulation model for flow rate of a pipeline explosion-proof valve system and the software Amesim was established.Through theoretical analysis, it was shown that the fundamental reason of mis-operation is the influence of the system flow rate and working temperature on flow rate characteristics of pipeline explosion-proof valve.Modeling and simulation were performed under the software Amesim environment, and test verification was conducted with a harbor equipment.Results showed that the method to adjust system’s valve parts and control working temperature can effectively avoid the mis-operation of pipeline explosion-proof valves;this method can provide a reference for the application and site debugging of pipeline explosion-proof valves.
