目前采用浮筒(浸离)式乙炔发生器进行氧乙炔焊接或切割的还是相当普遍的。乙炔气体的分子非常活跃,属于易燃、易爆气体。在生产施工中,时常因操作不当或焊接工具本身存在有缺陷,使乙炔管路回火,以至引起乙炔发生器爆炸造成不应有的损失。为了防止爆炸事故的发 The current use of buoy (leaching) type acetylene acetylene acetylene welding or cutting is still quite common. Acetylene gas molecules are very active, are flammable and explosive gases. In the production of construction, often due to improper operation or welding tool itself has flaws, so that the acetylene pipe tempering, and even cause acetylene generator explosion caused undue losses. In order to prevent the explosion accident hair
