隔爆外壳不传爆机理的研讨

Probing Into Explosion Isolation Mechanism of Flame-proof Enclosure

介绍了对隔爆外壳不传爆机理的传统解释，指出了传统解释所存在的问题及对该问题的新看法和观点，并从法兰面间隙的熄火作用和从间隙喷出的高压喷射流进入未燃气体的能量传播过程及由此引起的未燃气体浓度的变化过程这两个方面来揭示隔爆外壳的不传爆机理。

： This paper gives a description of the traditional explanation of explosion isolation mechanism of flame-proof enclosures, points out the problem present in this traditional explanation, puts forward new views on this problem and reveals the explosion isolation mechanism of flame-proof enclosures from the extinction effect of flange gap and the energy transmission process of high-pressure jet flow out of the gap into unburnt gas as well as the variation process of the concentration of unburnt gas.
