摘　　要：结合GB3836.2-2010的要求,对矿用呼吸和排液Ex元件的防爆阻火原理、结构形式、使用材料与安装方式进行了介绍,对其的承受压力能力试验、热试验、内部点燃不传爆试验等防爆型式试验的要求与方法进行了分析,同时对设计、使用、试验过程中的几个注意事项进行了探讨。Combined with the requirements of GB3836.2 -2010, explosion - proof flame arrester principle, structure form, materials used and installation means of mine breathing and discharge fuluid Ex components are introduced. Requirements and methods of flam- proof enclosure type test of its pressure capacity test, thermal test, not - transmission explosion test of interna lignition and other tests are analyzed. At the same time, a few notes in the process of designing, applying and testing process are discussed.
