摘　　要：核电设备的阀芯在工作一段时间后会发生磨损,需要更换,但阀杆一般还可以继续使用。为提升材料利用率,节省成本,可将更换的阀芯安装到旧阀杆上。采用销钉固定为组件,在更换时需要钻取销钉并进行配钻作业,使开设的孔与旧阀杆的孔保证较高的同轴度。文章研究了核岛调节阀阀芯组件销钉钻取工装和配钻工装,以确保钻取和配钻时的准确性和作业效率。The valve core of nuclear power equipment will wear out after working for a period of time and needs to be replaced.However,the valve stem can generally continue to be used.To improve material utilization and save costs,the replaced valve core will be installed on the old valve stem.Using pinfixation as a component,during replacement,it is necessary to drill the pin and perform matching drilling operations to ensure high coaxiality between the opened hole and the old valve stem hole.It is necessary to study the pin drilling and matching drillingfixtures for the core component of the nuclear island regulating valve to ensure accuracy and efficiency during drilling and matching.
