标准范围

ISO 9635-4:2006规定了空气阀的结构、性能要求和试验方法，这些空气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）或更大的液压操作空气灌溉阀，设计为直接操作，即通过浮子直接或通过机械连杆将力施加到闭孔器上。这些阀门可以通过可调先导阀施加的力来操作。

ISO 9635-4:2006 specifies construction and performance requirements and test methods for air 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 air irrigation valves of DN 15 (1/2 inch) diameter or greater, designed to be directly operated, i.e. the force is applied to the obturator by the float, either directly or via a mechanical linkage. The valves can be operated by a force applied through an adjustable pilot valve.
