Platform upper end is provided with electric power connection line, and heating tube fixing shell lower end is provided with heating tube, is arranged on the inside of the heating tube
There is quartz ampoule, magnesia powder is provided between the quartz ampoule and heating tube, is provided with outside the heating tube fixing shell anti-
Shield is provided with through-hole on the protective cover.
Further, the position of reaching the standard grade of the lead stick is set as taper thread structure, can effectively improve resistance wire on lead stick
It is secured.
Further, resistance wire is also equipped in the heating tube, and resistance wire is electrically connected with external power supply.
Further, the protective cover sheathing material is makrolon, there is preferable insulation performance, heat-resistant aging, nothing
Stress cracking.
Further, the through-hole diameter is 0.8CM, and electric power connection line is enabled to pass through.
Compared with prior art, the beneficial effects of the invention are as follows：This kind of electric heating tube is by turning to two resistance wires
Mariages ring type resistance wire be separately fixed at the reaching the standard grade on position of a pair of lead wires stick, resistance wire diameter can be reduced, realize resistance wire around
Silk, while reducing resistance wire load, increase electrothermal tube service life.
1, by filling magnesia powder in electric heating tube shell, good heat conductivility and insulation performance are made it have,
The heat for being conducive to heating wire generation transmits outward.
2, it by the way that quartz ampoule is arranged on the inside of electric heating tube shell, fits, can obviously carry on the inside of quartz ampoule and shell
The thermal conduction effect of high electric heating tube, heating speed are faster, more efficient.
3, by being arranged to taper thread structure in the position of reaching the standard grade of lead stick line, the resistance wire on lead stick can be effectively improved
Securely.
