座式酒精喷灯是由灯座(容器)1、铜帽2、预热盘3、升降器4、金属网5、灯管6、灯芯7、喷气孔8等组成,如图1所示. 使用时,旋下铜帽,用漏斗向灯座内注入2/3体积酒精,旋紧铜帽,使之不漏气.在预热盘内倒满酒精(不得溢出),点燃后,灯管因受热从而使管内酒精蒸发,当盘内酒精将近烧完,灯管内酒精蒸气不断从喷气孔排出至管口处时,便会自行着火成焰.旋松升降器上的螺旋,移动升降器调节空气的进入量和灯管内金属网的高低,升降器提得高,空气进入多,火焰高,温度也较高.反之温度降低.如果喷灯处于正常工作状态,当升降器升至最高位置时,火焰伸得较高,很稳定,并成浅蓝色.同时可听到连续不断的“嘶嘶”声.
The seat type alcohol torch is composed of a lamp holder (container) 1, a copper cap 2, a preheat plate 3, a lifter 4, a metal mesh 5, a lamp tube 6, a wick 7, and a fusible hole 8, as shown in Fig. 1. At that time, unscrew the copper cap and inject 2/3 volumes of alcohol into the lamp holder with a funnel. Tighten the copper cap so that it does not leak. Fill the preheated pan with alcohol (no spillage). After ignition, the lamp Heated so that the alcohol in the tube evaporates. When the alcohol in the pan is nearly burned, the vapor in the tube is continuously discharged from the fumarole to the nozzle. It will spontaneously become a fire flame. Loosen the screw on the lifter and move the lifter to adjust. The amount of air entering and the height of the metal mesh in the lamp, the lifter lifts high, the air enters more, the flame is higher, and the temperature is higher. Conversely, the temperature decreases. If the torch is in normal operation, when the lifter is raised to the highest position The flame spreads high, is stable, and turns light blue. At the same time, continuous “click” can be heard.
