某船舶系统引入外部海水对多个水舱进行注水，为保证不同海水压力下系统的安全，在管路中设置减压阀进行节流降压。为实现注水安全与速度的平衡，在设计过程中需研究减压阀的特性及其与系统的匹配性。基于AMESim平台构建减压阀及管路系统模型，通过仿真研究了减压阀的稳态及动态特性、系统总体匹配性，研究结果为船舶注水系统设计提供有效指导。
External seawater is introduced into a ship system to inject water into several tanks. In order to ensure the safety of the system under different sea water pressure, a pressure relief valve is set in the pipeline to reduce the system pressure. In order to achieve the balancing between the safety and speed of water injection, it is necessary to study the matching between the pressure relief valve and the system in the design process. Based on AMESim platform, the model of pressure relief valve and pipeline system is built. The turbulence and dynamic characteristics of the pressure relief valve and the matching of the system are studied through simulation. The research results can effectively guide the system design.
