标准范围

本国际标准规定了承压管道组件和安装方法的要求灌溉系统控制头，以下简称灌溉控制头，标称尺寸为包括200毫米。本国际标准仅适用于灌溉控制头的地上部件喷灌和微灌（微型喷头、滴灌等）。适用于基础灌溉控制头，其他灌溉控制和命令组件（电气、电子和液压）可安装在其上可以组装，但不处理这些附加组件。本国际标准不适用于可能需要防止故障的系统和/或组件灌溉控制头中冻结的水，如干水-桶形消防栓或其他类型的消防栓。本国际标准未规定单个部件的结构或操作要求构成灌溉控制头。这些要求在相关标准中对每一项进行了规定组成部分灌溉控制头包含农用化学品注射组件的系统应由防回流系统联锁装置、注射管线止回阀和其他安全装置保护符合当地标准或法规。本国际标准不包括此类设备。

This International Standard specifies requirements for the components and method of installation of pressurizedirrigation system control heads, referred to hereinafter as irrigation control heads, with a nominal size of up to andincluding 200 mm.This International Standard is applicable only to the above-ground components of irrigation control heads forsprinkler irrigation and micro-irrigation (mini-sprinklers, drip irrigation, etc.). It is applicable to the basic irrigationcontrol head, on which other irrigation control and command components (electrical, electronic and hydraulic) maybe assembled, but does not deal with these additional components.This International Standard is not applicable to systems and/or components that may be required to prevent thewater from freezing in the irrigation control head, such as dry-barrel hydrants or other types of hydrants.This International Standard does not specify construction or operating requirements for the individual componentsthat make up the irrigation control head. These requirements are specified in the relevant standards for eachcomponent.Systems whose irrigation control heads contain components for the injection of agricultural chemicals should beprotected by backflow prevention system interlocks, injection line check valves and other safety devices inaccordance with local standards or regulations. This International Standard does not cover such equipment.
