1、GB 5670.185 本标准适用于各种灌溉用的常用喷射仰角旋转式喷头。本标准参照采用国际标准ISO/DIS 7749/11983灌溉设备一旋转式喷头第一部分设计与运行要求。 1 喷头型式与型号 1.1 型式旋转式喷头的型式按驱动机构的特点分类和命名。如摇臂式、叶轮式、挡片式等。 1.2 型号旋转式喷头的型号由五部分组成,其意义如下：示例：进水口公称直径为15mm的双喷嘴摇臂式喷头： 15PY2进水口公称直径为50mm、装有换向机构的双喷嘴叶轮式喷头： 50PL2H进水口公称直径为40mm的单喷嘴垂直摇臂式喷头： 40PYC 2 基本参数 2.1 常用喷射仰角旋转式喷头的基本参数应

2、符合表1和表2中所列数值。附加机构的名称代号，用大写汉语拼音字母表示喷嘴数（单嘴喷头可以省略）型式代号：Y表示摇臂式，L表示叶轮式，D表示挡片式喷头喷头进水口公称直径，mm页码，1/10GB 5670.1852006-3-29file:/C:InetpubwwwrootdatagbdD5670A0A.htm 2.2 表1和表2中喷嘴直径一栏，对圆锥形喷嘴为出水口圆柱段的截面直径；对其他截面的喷嘴为当量直径。当量直径用下式计算： 2.3 当喷嘴直径的数值与表1、表2所列数值不等时,可用内插法计算喷头流量和射程。表 1 常用喷射仰角旋转式单嘴喷头基本参数式中: d喷嘴当量直径,mm；Q喷头实
