摘要

我公司两台330MW机组采用高压旁路(主蒸汽)和低压旁路(再热蒸汽)二级串联旁路装置。低压旁路蒸汽变换阀多次出现阀芯裂纹、吹损、机械损伤等情况,本文对阀门状况进行分析、归纳总结,以便为今后的低压旁路阀检修工作中消除缺陷提供一些帮助。
        Our company is two 330 MW units with high pressure bypass(main steam) and low pressure bypass(steam) two series connected by series. Low pressure bypass steam valve has occurred many times in the valve core crack, blowing loss,mechanical damage, etc.,this paper analyzes the status of the valve,summarized in order to provide some help for the future of the low pressure bypass valve repair work to eliminate defects.
