标准摘要
[中文适用范围]： 本文件规定了有关参数的测试程序和呈现结果的方法，这些参数定义了电动气动连续压力控制阀供应商文献中包含的主要特性，符合 ISO 10094-1。 本文件的目的是： ——通过标准化测试方法和测试结果的呈现来促进比较，以及 — 协助这些组件在压缩空气系统中的正确应用。 指定的测试旨在对不同类型的连续压力控制阀进行比较；这些不是对每个制造的产品进行的生产测试。 本文件中描述的测试适用于具有与大气相连的排气口的组件。 注 1：与非电动调节气动连续压力控制阀相关的试验在 ISO 6953-2 中规定。 注 2：ISO 10041-2 中规定了与电动气动连续流量控制阀相关的试验。 注 3：ISO 6953-3 提供了一种使用等温罐代替流量计来测量流量特性的替代动态测试方法。 然而，该方法仅测量正向流量和溢流流量特性的滞后曲线的减小流量部分。 [外文原描述]： This document specifies the test procedures and a method of presenting results concerning the parameters which define the main characteristics to be included in the supplier's literature of the electro-pneumatic continuous pressure control valves, conforming to ISO 10094-1. The purpose of this document is: — to facilitate comparison by standardizing the test methods and the presentation of the test results, and — to assist in the proper application of these components in compressed air systems. The specified tests are intended to allow comparison between the different types of continuous pressure control valves; these are not production tests to be carried out on each manufactured product. The tests described in this document are for components with an exhaust port vented to the atmosphere. NOTE 1 The tests related to non-electrically modulated pneumatic continuous pressure control valves are specified in ISO 6953-2. NOTE 2 The tests related to electro-pneumatic continuous flow control valves are specified in ISO 10041-2. NOTE 3 ISO 6953-3 provides an alternate dynamic test method for flow-rate characteristics using an isothermal tank instead of a flow meter. However, this method measures only the decreasing flow rate part of the hysteresis curve of the forward flow and relief flow characteristics.
