A flameproof enclosure’s effectiveness stems from its ability to contain flames within, txawm tias muaj kev tawg tshwm sim hauv cov khoom siv hluav taws xob casing. Qhov kev tiv thaiv no tau ua kom ntseeg tau los ntawm kev tiv thaiv cov nplaim taws los ntawm kev khiav los ntawm ntau qhov sib koom ua ke.
Ua raws li cov qauv tshwj xeeb hais txog qhov sib txawv, ntev, and surface roughness of these joints is crucial. These gaps not only extinguish the flames but also cool them effectively. They reduce the temperature of the flames passing through to a level insufficient for igniting any tawg mixtures that may be present outside the enclosure.
