摘要: 为对某百万千瓦核电站汽轮机旁排阀进行设计变更后的选型和验证工作,针对待选方案,建立了选型验证工作的流程。该流程包括设计验证和等比例试验两个阶段,通过CFD、有限元分析、模型试验、水流特性试验、空载特性试验以及汽流特性试验等方法,对各个方案进行了包括Cv特性、阀门控制性能等方面的综合对比,最终得到了理想的选型。提出的试验流程以及相关验证方法可为其他相关核电项目提供经验借鉴,同时其试验和理论计算结果所反映的不同类型阀门的特性和存在的问题也对旁排阀的选型提供了重要的参考。

Abstract: To make post-design variation selection and verification for the turbine bypass valve in a 1 000-MW nuclear power plant, the working flow is established according to the trim types for selection. The flow consists of two stages, designing verification and full-scale model test. Several methods including CFD, FEM, model test, water flow test, non-load test and actual steam flow test are used to conduct comparison on Cv characteristic and controllability among the trim types, and eventually, the ideal type is obtained. The test and verification flow and methods proposed in this paper can provide reference for other nuclear projects. Meanwhile, the characteristics and existing problems of different valve types reflected by the test and calculation results also can make important reference for the selection of the turbine bypass valve.

Key words: nuclear power station, steam turbine, bypass valve, selection, designing verification, steam flow test
