在电石缺少的情况下,我们进行了几次汽油切割的试验,结果尚满意,虽然切割速度和工作效率比氧乙炔差些,但对不经常使用切割的单位还是可以使用的。图1是汽油切割用的装置图。割炬是利用旧的氧乙炔割炬改装,方法如下(参阅图2)将割炬的混合管从头部卸去,把慢氧喷射器与慢氧导管连接(不可用锡焊因易脱落)。慢氧导管前部的喷口孔径应当与原有喷射器的小孔孔径相等。慢氧导管 In the absence of calcium carbide, we conducted several gasoline cutting tests and the results were satisfactory. Although the cutting speed and working efficiency are lower than those of oxyacetylene, it is still possible to use cutting units that are not often used. Figure 1 is a gasoline cutting device diagram. The torch was modified with an old oxyacetylene torch as follows (see Figure 2). The torch mixing tube was removed from the head and the slow oxygen injector connected to the slow oxygen tube (not available for soldering) . The orifice diameter of the front of the slow oxygen catheter should be equal to the orifice diameter of the original ejector. Slow oxygen catheter
