IBEDA阻火器产品介绍
EN ISO 5175-1 和 EN ISO 5175-2 标准的差异
符合 EN ISO 5175-1 标准的安全装置配有集成式阻火器，可在使用燃气和氧气混合物（例如乙炔/氧气混合物）时阻止回火。
符合 EN ISO 5175-2 的安全装置配置为不带集成阻火器。 当使用燃气和压缩空气混合物时，它们会阻止回火（当使用乙炔作为燃气时，不会产生回火）。
符合EN ISO 5175-2的气体止回阀（止回阀）可防止气体逆流。它们并非旨在阻止闪回。
DIFFERENCE IN THE STANDARDS EN ISO 5175-1 AND EN ISO 5175-2
Safety devices in accordance with EN ISO 5175-1 come with integrated flame arrestor stopping a flashback also when using fuel gas and oxygen mixtures, for example acetylene/oxygen mixtures.
Safety devices in accordance with EN ISO 5175-2 are configured without integrated flame arrestor. They stop a flashback when using fuel gas and compressed air mixtures (not flashback-resistance when using acetylene as fuel gas).
Gas non-return valves (check-valves) in accordance with EN ISO 5175-2 prevent reverse flow of gas. They are not designed to stop flashbacks.
符合 EN ISO 5175-1 的气体安全装置
符合 EN ISO 5175-1（带有集成阻火器的回火阻火器）的气体安全装置，用于焊接、切割和相关工艺。
IBEDA 回火阻火器按照国际标准 (EN ISO 5175-1) 和法规（TRAC207 - 回火阻火器）制造，并通过了德国 BAM 和美国 UL 等领先机构的独立认证。所有阻火器均根据 EN ISO 5175-1 进行 100% 测试。测试了阻火器、气体止回阀和密封性的功能。在测试过程中，集成的火焰屏障在其压力下与爆炸性的气体混合物发生回火。
IBEDA 为安全设备的年度检查提供了一种特殊的测试设备，该设备将根据国家关于流量、气体止回和密封性的特定规定进行。 PVGD 是一种易于操作的测试单元，旨在提供快速且简单的测试。
GAS SAFETY DEVICES ACCORDING TO EN ISO 5175-1
Gas safety devices according to EN ISO 5175-1 (flashback arrestors with integrated flame arrestor) for welding, cutting and allied processes.
IBEDA flashback arrestors are manufactured to international standards (EN ISO 5175-1) and regulations (TRAC207 - flashback arrestors) and are independently certified by leading institutes like the German BAM and the American UL. All flashback arrestors are 100% tested according to EN ISO 5175-1. The function of the flame arrestor, the gas non-return valve and the leak-tightness is tested. During the testing process, the integrated flame barrier is subjected to a flashback with the most explosive gas mixture at its maximum pressure.
IBEDA offers a special testing device for the annual inspection of safety devices which is to be conducted in accordance with country specific regulations on flow rate, gas non-return and leak tightness. The PVGD is an easily handled testing unit designed to provide quick and uncomplicated testing.
符合 EN ISO 5175-1 的安全装置的应用
符合 EN ISO 5175-1 标准的 IBEDA 气体安全装置产品系列（带阻火器的回火阻火器）用于不同的行业。 回火抑制器可用于单缸（安装有调节器）、割炬和切割机。 此外，它是钢瓶调节器、分配管线、分流点和气体分配器（板连接块）的理想保护。 回火防止器 (FBA) 提供气体止回阀（止回阀）、阻火器（阻火器）以及热切断阀。 IBEDA 回火抑制器 (FBA) 适用于所有标准气体类型。 如果安全装置类型包括热切断阀，这些具有多种安全功能的避雷器可提供的回火、气体回流和回火保护。
APPLICATION OF SAFETY DEVICES ACCORDING TO EN ISO 5175-1
The IBEDA product range on gas safety devices (flashback arrestors with flame arrestor) according to EN ISO 5175-1 are used in different various industries. The flashback arrestors can be used on single cylinders (regulator mounted), on torches as well as on cutting machines. Furthermore, it is the ideal protection at cylinder regulators, distribution lines, tapping points and gas distributors (board connection block). The flashback arrestors (FBA) offer a gas non-return valve (check valve), a flame arrestor (flame barrier) as well as a thermal cut-off valve. The IBEDA flashback arrestor (FBA) is suitable for all standard gas types. These arrestors with multiple safety functions provide optimal protection against flashback, gas return and additionally against burnback if the safety device type includes a thermal cut-off valve.
符合 EN ISO 5175-2 的气体止回阀（不带阻火器）
IBEDA 气体止回阀（安全装置）符合 EN ISO 5175-2（不带集成火焰屏障），可用作使用燃气和空气混合物操作的热过程的止回阀，或用作防回火气体非回流阀。
所有符合 EN ISO 5175-2 标准的安全装置（止回阀和防回火止回阀）均由柏林的 BAM 测试并获得 DVGW 认证。 阀门系统专为约 4 mbar 的低开启压力而开发。 气体止回阀可靠地防止气体倒流。
如果使用燃气和压缩空气混合物，防回火阀还可以阻止回火。 所有止回阀和防回流气体止回阀均经过 100% 质量测试。 测试气体单向阀的密封性和功能。
GAS NON-RETURN VALVES ACCORDING TO EN ISO 5175-2 (WITHOUT FLAME ARRESTOR)
IBEDA gas non-return valves (safety devices) in accordance with EN ISO 5175-2 (without integrated flame barrier) applicable as check valves for thermal processes that are operated with mixtures of fuel gas and air, or as flashback-resistant gas non-return valves.
All safety devices according to EN ISO 5175-2 (check valves and flashback-resistant non-return valves) are tested by BAM in Berlin and are DVGW certified. The valve systems are specially developed for low cracking pressures of about 4 mbar. The gas non-return valves reliably prevent the reverse flow of gas.
Flashback-resistant valves additionally stop flashbacks if fuel gas and compressed air mixture is used. All check valves and flashback-resistant gas non-return valves are subjected to a 100% quality test. The leak-tightness and the function of the gas non-return valve are tested.
根据 EN ISO 5175-2 应用安全装置
止回阀以及防回流气体止回阀用于保护热加工设备符合 EN746-2、管道系统和分流点。
APPLICATION OF SAFETY DEVICES ACCORDING TO EN ISO 5175-2
The check valves, as well as the flashback-resistant gas non-return valves are used to protect thermal process plants to EN746-2, pipeline systems, and tapping points.
