氧气瓶作为一种承压设备,管理不好就会发生爆炸事故。发生爆炸的重要原因之一,是瓶内混入了可燃气体。 氧气瓶内混入可燃气体的途径有二:一是制氧设备的因素而混入可燃气体;二是在施焊(割)中瓶内的氧气压力耗尽,或者剩余压力过低,加上焊嘴被堵塞,造成压力稍高的可燃气体倒灌入 Oxygen cylinders as a pressure equipment, poor management will be an explosion. One of the important reasons for the explosion is the mixture of flammable gas in the bottle. There are two ways to mix flammable gas in the oxygen bottle: one is to mix flammable gas with the oxygen making equipment; the other is to exhaust the oxygen in the bottle during the welding (cutting), or the residual pressure is too low, Was plugged, resulting in pressure slightly higher combustible gas into the influx
