IBEDA阻火器產品介紹
EN ISO 5175-1 和 EN ISO 5175-2 標準的差異
符合 EN ISO 5175-1 標準的安全裝置配有集成式阻火器，可在使用燃氣和氧氣混合物（例如乙炔/氧氣混合物）時阻止回火。
符合 EN ISO 5175-2 的安全裝置配置為不帶集成阻火器。 當使用燃氣和壓縮空氣混合物時，它們會阻止回火（當使用乙炔作為燃氣時，不會產生回火）。
符合EN ISO 5175-2的氣體止回閥（止回閥）可防止氣體逆流。它們并非旨在阻止閃回。
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 的氣體安全裝置
符合 EN ISO 5175-1（帶有集成阻火器的回火阻火器）的氣體安全裝置，用于焊接、切割和相關工藝。
IBEDA 回火阻火器按照國際標準 (EN ISO 5175-1) 和法規（TRAC207 - 回火阻火器）制造，并通過了德國 BAM 和美國 UL 等領先機構的獨立認證。所有阻火器均根據 EN ISO 5175-1 進行 100% 測試。測試了阻火器、氣體止回閥和密封性的功能。在測試過程中，集成的火焰屏障在其壓力下與爆炸性的氣體混合物發生回火。
IBEDA 為安全設備的年度檢查提供了一種特殊的測試設備，該設備將根據國家關于流量、氣體止回和密封性的特定規定進行。 PVGD 是一種易于操作的測試單元，旨在提供快速且簡單的測試。
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 的安全裝置的應用
符合 EN ISO 5175-1 標準的 IBEDA 氣體安全裝置產品系列（帶阻火器的回火阻火器）用于不同的行業。 回火抑制器可用于單缸（安裝有調節器）、割炬和切割機。 此外，它是鋼瓶調節器、分配管線、分流點和氣體分配器（板連接塊）的理想保護。 回火防止器 (FBA) 提供氣體止回閥（止回閥）、阻火器（阻火器）以及熱切斷閥。 IBEDA 回火抑制器 (FBA) 適用于所有標準氣體類型。 如果安全裝置類型包括熱切斷閥，這些具有多種安全功能的避雷器可提供的回火、氣體回流和回火保護。
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 的氣體止回閥（不帶阻火器）
IBEDA 氣體止回閥（安全裝置）符合 EN ISO 5175-2（不帶集成火焰屏障），可用作使用燃氣和空氣混合物操作的熱過程的止回閥，或用作防回火氣體非回流閥。
所有符合 EN ISO 5175-2 標準的安全裝置（止回閥和防回火止回閥）均由柏林的 BAM 測試并獲得 DVGW 認證。 閥門系統專為約 4 mbar 的低開啟壓力而開發。 氣體止回閥可靠地防止氣體倒流。
如果使用燃氣和壓縮空氣混合物，防回火閥還可以阻止回火。 所有止回閥和防回流氣體止回閥均經過 100% 質量測試。 測試氣體單向閥的密封性和功能。
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.
根據 EN ISO 5175-2 應用安全裝置
止回閥以及防回流氣體止回閥用于保護熱加工設備符合 EN746-2、管道系統和分流點。
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.
