摘　　要：在国内核电厂的阀门检测工作中,阀杆在阀门运行时受到的推力是衡量阀门状态的重要参数之一。考虑到核电站现场特有的辐照环境,基于电阻应变测量原理设计了一种可快速安装、拆卸于阀杆的推力传感器,实现了阀杆推力参数测量的数字化。功能试验测试结果显示:该推力传感器的测量精度达到了设计要求。In domestic nuclear power plants(NPT),the thrust load on the stem is a critical parameter to evaluate operating condition of valves in the valves testing.Considering irradiation environment of the NPT,a conveniently mounting or dismounting thrust sensor was designed based on the resistance strain gauge method to realize digital measurement of the stem thrust.Performance test shows that this thrust sensor can meet design requirements.
