核电厂动力驱动阀门端部加载试验的适用范围和力矩计算

Scope of Application and Torque Calculation of End Loading Test of Power Drive Valve in Nuclear Power Plant

端部加载试验是核电厂阀门鉴定项目之一,本文首先介绍了端部加载试验的执行标准,然后对阀门端部加载试验的适用范围进行了归类,最后对端部加载试验力矩计算公式中的参数进行了说明,并依据核电厂某台阀门的实际参数计算了力矩值。

End loading test is one of the valve identification projects of nuclear power plant,this paper first introduces the implementation standards of end loading test,then classifies the scope of application of valve end loading test,and finally describes the parameters in the torque calculation formula of end loading test,and calculates the torque value according to the actual parameters of a valve in a nuclear power plant.
