摘要
介绍了对阀门外载荷弯曲试验原理、试验方法以及载荷参数选取与统计分析的研究,给出了阀门外载荷弯曲试验模型和参数,提供了评定管线阀门承受外载荷可靠性依据。
The model of valve extra-load bending test is designed and its test parameters are put forward, through those investigations on principle of valve extra-load bending test, test method, design and statistical analysis of test parameters. Provides reliability evaluation basis for extra-load on pipeline valves.
