标准范围
ISO 9635-5:2006规定了控制阀的结构、性能要求和试验方法,这些控制阀用于在温度不超过60°C的灌溉系统中运行,其中可能含有肥料和农业中使用的其他类型和浓度的化学品。它适用于直径为DN 15(1/2英寸)或更大的液压操作控制灌溉阀,设计用于从完全打开到完全关闭的任何位置。阀门可以直接操作(即通过弹簧或隔膜向闭孔器施加的力),也可以通过先导操作(即通过隔膜通过可调先导阀施加的力)。
ISO 9635-5:2006 specifies construction and performance requirements and test methods for control valves, intended for operation in irrigation systems with water at temperatures not exceeding 60 °C, which can contain fertilizers and other chemicals of the types and concentrations used in agriculture. It is applicable to hydraulically operated control irrigation valves of DN 15 (1/2 inch) diameter or greater, designed to operate in any position, from fully open to fully closed. The valves can either be directly operated (i.e. the force applied via a spring or diaphragm to the obturator), or pilot-operated (i.e. the force is applied through an adjustable pilot valve via a diaphragm).
