又名 FP A天然气 阻火器 ，采用两个 GZW-1阻火器 组合而成，广泛应用于冶金、化工等行业的天然气输送管道，如加热炉燃料气、石油液化气、煤矿瓦斯排放、也适用民用煤气管道。 FPA gas flame arrester, also known as FP A natural gas flame arrester , is a combination of two GZW-1 flame arresters . It is widely used in natural gas pipelines in metallurgy, chemical industry and other industries, such as heating furnace fuel gas, petroleum liquefied gas, coal mine gas. Emissions are also applicable to civilian gas pipelines. It can effectively cut off the ignition source caused by the sharp friction between the debris in the high-speed airflow and the pipe wall, and prevent the reverse propagation of the flame in the pipe under abnormal conditions. Prevent the occurrence of pipeline explosion accidents. The safety fire resistance speed of this product is 1425m / s; the ultimate fire resistance speed is 1605m / s. Customers can directly weld and connect this product to the appropriate parts of natural gas pipelines and run.
阻火器 的 结构特点： Structural characteristics of FPA gas fire arrester :
1. This product has quenching effect on subsonic or supersonic flames in pipes;
2. This product generally has a matching flange, the standard is HGJ standard;
3. This product can be matched with the pipeline system, and can also be connected with regulating valves, breathing valves, etc .;
阻火器 的工作原理： The working principle of FPA gas fire arrester :
阻火器 是利用金属波纹盘之间狭缝间隙，对管道中传播的亚音速或超音速火焰具有淬熄作用的原理设计制造的，本产品的连接法兰按 HG20595-97 凹凸面带颈对焊钢制管法兰设计制造，用户需选用其它标准的连接法兰，请在订货中予以说明 , 对于 PN ＞ 4.0MPa 的气体 阻火器 。 FPA gas fire arrester is designed and manufactured with the principle of quenching the subsonic or supersonic flame propagating in the pipeline by using the gap between the metal corrugated disks. The neck butt-welded steel pipe flange is designed and manufactured. Users need to choose other standard connection flanges. Please specify in the order . For gas flame arresters with PN > 4.0MPa .
