Road vehicles — Liquefied petroleum gas (LPG) fuel system components — Part 19: Gas-tube pressure relief valves 道路车辆 液化石油气(LPG)燃料系统部件 第19部分:气体管减压阀
发布日期: 2025-03-06
本文件规定了液化石油气燃料(LPG)部件的一般要求和定义,用于ISO 3833定义的机动车辆。它还提供了一般设计原则,并规定了说明和标记的要求。 本文件适用于根据ISO 9162使用气体燃料的车辆(单燃料、双燃料或双燃料应用)。它不适用于: -燃料容器; -固定式燃气发动机; -容器安装硬件; -电子燃料管理; -加油容器。 可以检查本文件中未具体说明的其他组件是否符合ISO 20766系列任何适用部分的标准,包括进行适当的功能测试。除非另有说明,本文件中对压力的所有引用均被视为表压。 本文件适用于工作压力在110 kPa(20°C时富丁烷)和840 kPa(20°C时丙烷)范围内的设备。可以通过按适当的系数(比率)调节压力来适应其他工作压力。

This document specifies general requirements and definitions of liquefied petroleum gas fuel (LPG) components, intended for use on the types of motor vehicles as defined in ISO 3833. It also provides general design principles and specifies requirements for instructions and marking.

This document is applicable to vehicles (mono-fuel, bi-fuel or dual-fuel applications) that use gaseous fuels in accordance with ISO 9162. It is not applicable to:

     fuel containers;

     stationary gas engines;

     container mounting hardware;

     electronic fuel management;

     refuelling receptacles.

Miscellaneous components not specifically addressed in this document can be examined for conformity with the criteria of any applicable part of the ISO 20766 series, including testing to the appropriate functional tests.

All references to pressure in this document are considered gauge pressures unless otherwise specified.

This document applies to devices that have a service pressure in the range of 110 kPa (butane rich at 20 °C) and 840 kPa (propane at 20 °C). Other service pressures can be accommodated by adjusting the pressure by the appropriate factor (ratio).
