Изобретение относится к области авиационной техники, а именно к топливным системам самолетов, и касается систем дренирования топливных баков. Целью изобретения является повышение надежности защиты топливных баков самолета от проникновения в них пламени путем снижения скорости его распространения по дренажным трубопроводам за счет того, что в устройстве, содержащем сообщенный с атмосферой посредством воздухозаборного трубопровода с патрубком дренажный бак, связанные с ним трубопроводы дренирования топливных баков, пламепреградитель установлен в воздухозаборном патрубке, при этом пламепреградитель выполнен в виде цилиндра с наполнителем из колец с диаметром и высотой равными 4 - 6 мм, соотношением диаметра кольца и образующей внутренней поверхности пламепреградителя составляющим 0,04 - 0,02 соответственно. 3 ил.The invention relates to the field of aviation technology, namely to the fuel systems of aircraft, and relates to the drainage systems of fuel tanks. The aim of the invention is to improve the reliability of the protection of aircraft fuel tanks from the penetration of flame into them by reducing the speed of its propagation through drainage pipelines due to the fact that in the device containing a drain tank connected to the atmosphere through an air intake pipe with a branch pipe, a flame arrester is installed in the air intake manifold, while the flame arrester is made in the form of a cylinder filled with rings of diameter and height bubbled 4 - 6 mm, and the ratio of ring diameter plamepregraditelya forming the inner surface is 0.04 - 0.02, respectively. 3 il.
