文丘里喷嘴的详细信息 /*110922_中文版_新中间页_中间_300*250*/ var cpro_id = 'u620430'; 概述 文丘里喷嘴按国标GB/T2624-93进行设计制造,按JJG640-94进行检定。无需实流标定。文丘里喷嘴所要求上、下游直管段短、压力损失小、性能稳定、维护方便,广泛应用于石油、化工、电力、冶金、污水测量等行业。适用范围 1、公称直径:65mm≤DN≤500mm 2、公称压力:PN≤10MPa 3、孔径比:0.316≤β≤0.775 4、雷诺数范围:1.5×105≤ReD≤2×106 5、:1级结构形式 文丘里喷嘴由收缩段、圆筒形喉部和扩散段组成,其取压方式为上游取压口为角接取压,下游取压口为喉部取压,具体结构见下图。 文丘里喷嘴扩散段的扩散角Ψ≤30°,扩散段的长度L对流出系数无影响,但影响其压力损失,可以像经典文丘里管一样,把文丘里喷嘴截尾。标准孔板圆缺孔板限流孔板:https://www.jsemck.com/cpzs.asp?ProClass=63https://www.fengdaojiaoyi.com/g_list.asp?id=92平衡孔板流量计:https://www.jsemck.com/cpzs.asp?ProClass=85https://www.fengdaojiaoyi.com/g_list.asp?id=101ISA1932标准喷嘴长径喷嘴文丘里喷嘴:https://www.jsemck.com/cpzs.asp?ProClass=64https://www.fengdaojiaoyi.com/g_list.asp?id=93经典文丘里管插入(内藏)式双文丘里管:https://www.jsemck.com/cpzs.asp?ProClass=65https://www.fengdaojiaoyi.com/g_list.asp?id=94电磁流量计:https://www.jsemck.com/cpzs.asp?ProClass=71https://www.fengdaojiaoyi.com/g_list.asp?id=95V锥流量计:https://www.jsemck.com/cpzs.asp?ProClass=73https://www.fengdaojiaoyi.com/g_list.asp?id=96楔形流量计:https://www.jsemck.com/cpzs.asp?ProClass=74https://www.fengdaojiaoyi.com/g_list.asp?id=97弯管流量计:https://www.jsemck.com/cpzs.asp?ProClass=75https://www.fengdaojiaoyi.com/g_list.asp?id=98阿牛巴流量计:https://www.jsemck.com/cpzs.asp?ProClass=66https://www.fengdaojiaoyi.com/g_list.asp?id=102威力巴流量计:https://www.jsemck.com/cpzs.asp?ProClass=66https://www.fengdaojiaoyi.com/g_list.asp?id=103
