设计了一种用于机械泵驱动两相流系统的新型被动截止阀。对设计的膜片式被动截止阀进行了ANSYS静态结构分析和过流特性仿真。对该截止阀的正向过流和反向截流的性能进行了实验测试。结果显示, 截止阀的各项性能完全能够满足机械泵的要求。设计的截止阀对机械泵流体输出性能提高的研究具有参考意义。

A new passive check valve for Mechanical Pumped Cooling Loops (MPCL) is designed. Static structural analysis and flow characteristic simulation of the diaphragm-type passive check valve designed are performed by the software ANSYS. The forward flow and leak flow characteristics of the check valve are tested experimentally. The results show that the performance of the check valve can completely meet the requirements of the mechanical pump. The check valve is of referential significanceto the research on the improvement of the performance of mechanical pumps.
