弹簧的刚度值K是衡量其工作性能的标志。测定安全阀专用弹簧的刚度是安全阀校验工作中一项重要内容。获得某一安全阀所用弹簧的刚度值有三种方法。 1 公式法这种方法适合于新弹簧的K值确定。据公式:K=10~4/[(D_w/d-1)~3·n/d]可知:如果测量出该弹簧的外径D_w、钢丝直径d及工 Spring stiffness K is a measure of its performance. Determination of the safety valve spring stiffness is an important part of the safety valve calibration work. There are three ways to get the stiffness of a spring used by a safety valve. 1 formula method This method is suitable for determining the new spring K value. According to the formula: K = 10 ~ 4 / [(D_w / d-1) ~3 · n / d] Know: If you measure the outer diameter of the spring D_w,
