[中文适用范围]： 本文件规定了正常操作的自动排气阀（以下简称“阀门”）的安全、结构、性能和测试要求。 本文件适用于声明最大工作压力不超过500kPa、公称连接尺寸不超过DN 100（4英寸）的阀门，用于燃气燃烧器的气体控制装置或使用天然气、人造气或液化石油气（LPG）等气体燃料的器具。不适用于腐蚀性气体和废气。 本文件适用于： 电动操作的阀门和由流体驱动的阀门，其中这些流体的控制阀门由电力驱动，但不包括用于切换控制信号或驱动能量的任何外部设备；装有开启位置指示开关的阀门。 本文件仅涵盖型式测试。 [外文原描述]： This document specifies safety, constructional, performance and testing requirements of normally open automatic vent valves, hereafter referred to as “valves”. This document applies to valves with a declared maximum operating pressure up to and including 500 kPa of nominal connection sizes up to and including DN 100 (4”), for use in gas control train of gas burners or in appliances using gaseous fuels such as natural, manufactured or liquefied petroleum gas (LPG). It is not applicable to corrosive and waste gases. This document applies to: — electrically operated valves and to valves actuated by fluids where the control valves for these fluids are actuated electrically, but not to any external devices for switching the control signal or actuating energy; — valves fitted with open position indicator switches. This document covers type testing only.
