Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figs. 1-2, a kind of electrothermal tube seal, including electrothermal tube 1, heating wire 2, magnesia powder 3, draw stick 4, spiral shell
Line steel plug 5, copper sheet a6, porcelain head 7, copper sheet b8 and taper copper rod 9 are equipped with heating wire 2, the electric heating in 1 inner cavity of electrothermal tube
Magnesia powder 3 is filled in 1 inner cavity of pipe, 2 upper end of heating wire, which is connected with, draws stick 4, and 1 upper end of electrothermal tube is screwed with screw thread
Steel plug 5,5 upper end of screw-thread steel plug are equipped with copper sheet a6, and the 5 upper end outer wall of screw-thread steel plug is screwed with porcelain head 7, the porcelain head 7
