Further, the online position 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 and external power supply are electrically connected.
Further, the shield sheathing material is polycarbonate, 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 utility model has the beneficial effects that this kind of electric heating tube by by two resistance wires around
Manufactured mariages ring type resistance wire is separately fixed on the online position of a pair of lead wires stick, can reduce resistance wire diameter, realizes resistance
Absorption filament-coiling, while reducing resistance wire load, increase electrothermal tube service life.
1, by filling magnesia powder in electric heating tube shell, good heating conduction 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 mention 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 online position of lead stick line, the resistance wire on lead stick can be effectively improved
Securely.
