阀门是钢铁企业的常耗备件之一,其具有种类规格分布广、生产企业多、单价差异大等特点,文章通过对常用种类阀门的不同公称直径对应的质量与价格的研究,得出阀门的单价与公称直径间存在线性关系,而阀门的质量与公称直径亦有直接关系,并基于此提出建立阀门控制价计算模型,建立阀门单价与质量比值走势图,探索阀门消耗真实成本,以便更加准确地预测阀门单价,为阀门的招标采购提供科学的价格参考。 Valve is one of the spare parts often consumed by steel enterprises. It has the characteristics of wide range of specifications and specifications, large number of manufacturing enterprises and large unit price differences. Through the study of the quality and price of different nominal diameters of common types of valves, There is a linear relationship between the unit price and the nominal diameter, and the quality of the valve is also directly related to the nominal diameter. Based on this, a calculation model of the valve control price is established, and the unit price-to-mass ratio graph of the valve is established to explore the true cost of the valve consumption so as to be more accurate To predict the valve price, the tender for the valve to provide a scientific price reference.
