Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of leak stopping thermocouple, including ceramic protecting pipe
1, the left end of the right end and high-temperature metal reinforced pipe A2 of the ceramic protecting pipe 1 is welded by high temperature inorganic glue, the high temperature gold
Belong to and be welded with main body mounting flange 3 on the tube wall of reinforced pipe A2, it is stifled that the right end of the high-temperature metal reinforced pipe A2 is welded with first
Flange 4 is leaked, the first leak stopping flange 4 is bolted with the second leak stopping flange 5,5 right end of the second leak stopping flange weldering
It is connected to high-temperature metal reinforced pipe B6, the 5 left end sealing welding of the second leak stopping flange is connected to armouring platinum rhodium 7, and the high-temperature metal adds
