The utility model provides a high temperature alloy cylinder temperature equalizing block for calibrating cheap metal armoring electric thermocouples, thereby improving the evenness of the temperature field of the pipe type electric thermocouple calibration furnace, and improving the calibration accuracy. The piping type temperature equalizing block comprises a high temperature alloy cylinder temperature equalizing block, and has the structure key points that blind holes are evenly arranged on the surface edge on one end of the high temperature alloy cylinder temperature equalizing block, one is a blind hole of a standard electric thermocouple, the others are blind holes of checked cheap metal armoring electric thermocouples, and the other end surface of the high temperature alloy cylinder temperature equalizing block is provided with the blind holes of temperature-control electric thermocouples.
Description
Technical field:
The utility model relates to the tubular thermocouple assay furnace, in order to improve the homogeneity of its temperature field.
Background technology:
Measurement unit and enterprises and institutions use the tubular thermocouple assay furnace usually when calibration cheap metal armoured thermocouple, existing common way is that the standard of armoured thermocouple and its cover protection tube is tied up bunchy, directly places the tubular furnace center to calibrate.
Because the temperature field of full load often can not reach the standard-required that any point-to-point transmission temperature difference is not more than 1 degree centigrade in the tubular thermocouple assay furnace, the therefore lack of homogeneity of temperature, it is inaccurate to cause calibrating cheap metal armoured thermocouple result, and uncertainty is bigger than normal.
The utility model content:
The utility model is exactly at the problems referred to above, and a kind of high temperature alloy right cylinder block that the cheap metal armoured thermocouple is used of calibrating is provided, and to improve tubular thermocouple calibrating furnace temperature field uniformity, improves calibration accuracy.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises high temperature alloy right cylinder block, evenly be provided with blind hole on the one end surfaces edge of its structural feature high temperature alloy right cylinder block, one of them is the blind hole of standard couple, and all the other are the blind hole that is calibrated the cheap metal armoured thermocouple; The blind hole of temperature-control heat couple is set on the surface of the other end of high temperature alloy right cylinder block.
The beneficial effects of the utility model:
1, provide a uniform and stable temperature field:
What the high temperature alloy right cylinder block material in the utility model was chosen is that nickel-chrome is processed into through particular design, Heat stability is good during high temperature, thermal inertia are bigger, after in the tubular thermocouple assay furnace, putting into this high temperature alloy right cylinder block, can make assay furnace realize following index: count that the temperature difference is not more than 0.5 ℃ in the axial 30mm at the bottom of the hole, the temperature difference absolute value between any hole, same cross section, bottom, hole is not more than 0.25 ℃.After furnace temperature is stable, even the temperature in the tubular thermocouple calibrating body of heater has certain fluctuation, because special shape design of the present utility model and material selection, furnace temperature can not be affected yet, the warm field uniformity that can improve the tubular thermocouple assay furnace is poor, improves cheap metal armoured thermocouple calibrating quality.At present, high temperature alloy right cylinder block of the present utility model has obtained national technical regulation approval.
2, satisfy national technical regulation requirement, save and change the stove cost:
The utility model does not need the structure of modification to tubular furnace on the basis of tubular thermocouple assay furnace, make tubular thermocouple calibrating furnace temperature field index satisfy national technical regulation requirement, can carry out normal calibration operation.
