摘　　要：核级电动闸阀端部加载试验是通过对阀门管端施加载荷,测定载荷施加过程中力和应变的变化,考核阀门的刚度、强度以及在载荷作用时和作用后的性能指标,验证当阀门受到所有管端载荷及压力和自重在内的正常工作载荷作用时阀门的可操作性。本文探讨了核级电动闸阀样机端部加载试验的技术要点,并以一实际样机试验为例,描述了核级电动闸阀样机端部加载试验的试验方法及其试验结果。A type of nuclear class 1 gate valve was tested in the end-loading qualification test. The test intends, test content, test device, test method and results were described in this paper. By performing the force loading on the pipe flange of the valve, the force and stress of the valve was tested. The rigidity, intensity and the functionality of the valve was examined during and after this end-loading qualification test. The test results show that the integrity and operability of this gate valve satisfy the requirement of related documents.
