标准摘要
[中文适用范围]： 本标准规定丁“文丘里式差压液体添加射流器”的设计、操作须知及测试方法。这种“文丘里式差压 液体添加射流器”是灌溉系统中用来向系统注入可溶性化学物，包括液体肥料、水溶性液体肥料、酸类、 腐蚀性溶液、杀虫剂、除草剂以及其他液态添加剂。本标准不含向饮用水供水系统中回流防止装置，接 近文丘里式射流器的安装装置被包含在防水措施细则中。 [外文原描述]： ISO 15873 specifies the construction of, and operational requirements and test methods for, differential pressure Venturi-type liquid additive injectors -- a component of systems used to inject chemicals, including liquid fertilizers, liquid solutions of water-soluble fertilizers, acids, caustics, pesticides, herbicides and other liquid additives, into irrigation systems. ISO 15873 does not specify means of preventing backflow of liquid additives to potable water supply systems, the assembly of such means, near to the Venturi injector, being covered by water protection regulations.
