管路防爆阀误动作机理与抑制方法研究

Mis-operation mechanism and suppressing method for pipeline explosion-proof valve

根据管路防爆阀在工程应用中容易误动作的实际难题,建立了管路防爆阀流量与Amesim仿真模型,从理论上分析了误动作产生的根本原因是系统流量和工作温度对管路防爆阀流量特性的影响,在Amesim软件环境下进行建模仿真,并在某港口设备进行了实验验证。通过调节系统阀件,控制工作温度可以有效避免管路防爆阀误动作,这对管路防爆阀的应用和现场调试提供了参考。

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.
