阀门设计计算中安全性与经济性权衡的探讨

Discussion on the Balance Between Safety and Economy in Valve Design and Calculation

在阀门设计的复杂过程中,设计者对计算公式来源的追溯和参数变量的精准选择均面临诸多挑战。这些选择不仅直接关联到阀门的安全性能,同时也深刻影响着其经济效益。本文从安全性和经济性的双重维度出发,对阀门设计中常用的壁厚计算公式进行了细致探讨,并对不同标准下的许用应力安全系数规定以及压力-温度额定值设定进行了对比分析。这些研究成果为阀门设计的优化和结构的完善提供了宝贵的参考依据,具有重要的实践价值。

In the complex process of valve design,designers face many challenges in tracing the source of calculation formulas and accurately selecting parameter variables.These choices are not only directly related to the safety performance of the valve,but also profoundly affect its economic benefits.This article explores in detail the commonly used wall thickness calculation formulas in valve design from the dual dimensions of safety and economy,and compares and analyzes the allowable stress safety factor regulations and pressure temperature rated value settings under different standards.These research results provide valuable reference basis for the optimization of valve design and the improvement of structure,and have important practical value.
