汽油切割機從汽油罐到割嘴都是液體，汽油罐，液體是不回火的（扯淡所以本機*不會發生回火現象）即使對汽油罐內汽油直接點火也只能使汽油緩慢燃燒，不會發生劇烈燃燒和爆炸。（裝了該防爆材料的油罐甚至可帶油對油罐進行補焊缺口）。直至耗盡輸油管中的汽油而不會發生汽油飛濺導致火患危及人身安全的險情，這是其它汽油割炬所無法匹敵的。汽油罐上配有常壓恒定安全閥，一方面能夠消除汽油罐在封閉狀態下長時間工作后罐內所產生的負壓，另一方面能*汽油罐不小心傾倒時罐內的汽油不會泄露出來。（圖/文http://www.alsdl.com/）

Gasoline cutting machine to cut from the gasoline tank mouth is liquid, liquid is not tempered ( nonsense so the machine will never happen to backfire phenomenon, gasoline tank filling to the national Ministry of public security, the Ministry of labor recommend high-tech material, even on the gasoline tank of gasoline direct ignition can make gasoline burn slowly, not burning and explosion. ( with the explosion-proof material tank even with oil on the tank repair welding gap). Until exhausted oil pipe of gasoline instead of gasoline splash lead to fire endangered the personal safety of danger, which is unmatched by other gasoline cutting torch. Gasoline tank with a constant pressure safety valve, one can eliminate the gasoline tank in a closed state after long time working tank produced by the negative pressure, on the other hand, can guarantee the gasoline tank accidentally dumped when the tank of petrol will not leak out.
