摘　　要：在试验装置上开展了压水堆运行参数范围内动力驱动阀门的流体阻断试验研究和止回阀的动态逆流与静态逆流试验研究。试验结果表明:开展动力驱动阀门流体阻断试验时,在设施能力不足的情况下可将阀门开启度适当减小,也能验证阀门阻断流体的能力;止回阀静态逆流试验相较于动态逆流试验能更苛刻地考验止回阀的阻断性能。本文结果可为开展同类验证试验在试验方法的选取上提供依据。Flow interruption capability test of the power-operated valve and the dynamic and static state reverse-flow test of the check valve within the operating parameter of pressurized water reactor were carried out on the test equipment.The test results show that when the capability of the power-operated valve is insufficient in flow interruption capability test,the interruption capability could still be well performed even the opening of the valve is appropriately decreased.The static state reverse-flow test could more strictly test the capability of the check valve than the dynamic state reverse-flow test.The results in this thesis could provide basis for the method choose of the same type test research.
