Property, and sealing, prevent the leakage of measured medium, there is good practical value.
The purpose of this utility model and to solve its technical problem be to be realized using following technical scheme.According to this reality
With a kind of extension type thermocouple thermometer of new proposition, it include thermocouple body 1, hold-down grid 2, stuffing-box 4 and
Loose flange 8, wherein loose flange 8 are set in thermocouple body 1, and this loose flange 8 is upper with thermocouple body 1 contact position
Portion offers annular groove, is provided with stuffing-box 4 in it, is filled with filler 6 in described filler letter 4, and described filler 6 passes through filler pressure
Plate 2 compresses；It is connected by regulating bolt 3 between described filler pressing plate 2 and loose flange 8；It is additionally provided with described thermocouple body 1
Rule 9.
The purpose of this utility model and solve its technical problem can also be come using following technical measures real further
Existing.
Aforesaid extension type thermocouple thermometer, is provided with O-shaped close between wherein said stuffing-box 4 and loose flange 8
Seal ring 7.
Aforesaid extension type thermocouple thermometer, is provided with packing press ring between wherein said filler 6 and hold-down grid 2
5.
Length in its insertion pressure pipeline of this utility model extension type thermocouple or pressure vessel is adjustable in,
The motility adjustment being set to thermocouple intubating length of good sealing structure and rule provides safeguard thus strengthening same
The suitability of one thermocouple and versatility.This utility model increased the product category of the sector, enhance products configuration and
The motility using, commercially has practicality and generalization.

Specific embodiment
For further illustrating that this utility model is to reach technological means and effect that predetermined goal of the invention is taken, below
In conjunction with accompanying drawing and preferred embodiment, to according to the utility model proposes its specific embodiment party of extension type thermocouple thermometer
Formula, structure, feature and its effect, after describing in detail such as.
Refer to Fig. 3, it is the structural representation of this utility model extension type thermocouple thermometer, this electric thermo-couple temperature
Meter includes thermocouple body 1, hold-down grid 2, stuffing-box 4, packing press ring 5 and loose flange 8.Wherein said thermocouple is originally
Body 1 is provided with rule 9, when the insertion depth of thermocouple needs adjustment, can be realized to heat according to the scale on rule 9
The accurate adjustment of galvanic couple body 1 insertion depth, and the setting of this rule 9 also can achieve the reality to thermocouple body insertion depth
When accurately understand.
Described loose flange 8 is set in thermocouple body 1, and this loose flange 8 and thermocouple body 1 contact position is upper
