标准范围

本文件仅适用于手动启动的阀门。本文件规定了在稳态条件下，当水流过农业灌溉阀时，测定其压力损失的试验方法。所提供阀门性能规范的范围和精度将有助于农业灌溉系统设计师比较各种类型阀门的压力损失。压力损失的测量为确定压力损失和通过阀门的流量之间的关系提供了一种方法。本文件还描述了报告相关测试数据的方法。未尝试定义产品用途、设计或应用。该试验方法适用于入口和出口标称尺寸相等的阀门。

This document applies to manually-activated valves only.This document specifies a test method for determining the pressure loss in agricultural irrigation valves under steady-state conditions when water flows through them. The scope and accuracy of the valve performance specifications presented will assist agricultural irrigation system designers in comparing pressure losses through various types of valves.The measurement of pressure losses provides a means for determining the relationship between pressure loss and flow rate through the valve.This document also describes the method of reporting pertinent test data.No attempt is made to define product use, design or applications.The test method is suitable for valves with equal inlet and outlet nominal sizes.
