本欧洲标准规定了弹簧加压泄压阀和热膨胀阀的设计和测试要求，用于: - 静压LPG压力容器， 注意压力容器可以位于地面，地下或丘陵之上。 - 道路油罐车，轨道油罐车，油罐容器或可拆卸坦克上的LPG压力容器。 本文档不涉及生产测试。 规范性附录B规定了在-40°C条件下进行的测试，用于在极端低温条件下使用的阀门。 EN 14071规定了隔离装置，转换歧管和排气管等泄压阀附件的要求。 EN 14570标识了静压力容器的泄压阀容量的要求。 EN 12252标识了道路油罐的泄压阀容量的要求。 根据本标准设计的阀门专门用于LPG应用。根据EN ISO 4126 1制造的阀门也可用于某些LPG应用。 LPG泄压阀使用的术语在附件A中进行了描述

This European Standard specifies the requirements for the design and testing of spring loaded pressure relief valves and thermal expansion valves for use in: - static LPG pressure vessels, NOTE The pressure vessels can be situated above ground, underground or mounded. - LPG pressure vessels on road tankers, rail tankers, tank-containers or demountable tanks. This document does not address production testing. Normative Annex B prescribes testing with conditioning at - 40 °C for valves for use under extreme low temperature conditions. The requirements for pressure relief valve accessories such as isolating devices, changeover manifolds and vent pipes are specified in EN 14071. EN 14570 identifies the requirements for the pressure relief valve capacities for static pressure vessels. EN 12252 identifies the requirements for the pressure relief valve capacities for road tankers. Valves designed in accordance with this standard are specifically for use in LPG applications. Valves manufactured in accordance with EN ISO 4126 1 may also be used in certain LPG applications. Terms used with LPG pressure relief valves are described graphically in Annex A.
