Description
Technical field
The utility model belongs to calibration of thermocouple technical field, relates to the stationary installation that a kind of calibration of thermocouple uses.
Background technology
When utilizing assay furnace to carry out temperature test to high temperature armoured thermocouple, the temperature-measurement principle of thermopair is compared by standard and tested thermopair, finally draws the error of thermopair.During current measurement armoured thermocouple, be the circular distal of armoured thermocouple propped up with a cross frame, the measure portion of thermopair is then fixed together with standard platinum rhodium 10-platinum.But thermopair and standard can not be fixed by this type of cross frame completely; when carrying out subsequent operation, can because fix loosely play, because standard is protected in quartz socket tube; thermopair play easily causes quartz protecting tube to damage, thus generation standard is damaged, the problem such as fracture.Insecurely occur that the measuring junction position of standard and thermopair offsets because fixing, cause data error in verification process bigger than normal.The utility model is the certification fixture of a kind of fixing many thermopairs developed under laboratory ambient temperature.
Utility model content
The technical problems to be solved in the utility model:
Improve the accuracy and precision of measuring thermopair, improve workman's work efficiency, reduce because standard damages the waste caused, improve the quality of products.
The technical solution of the utility model:
The stationary installation that a kind of calibration of thermocouple uses, comprise fixed base plate 1, test side fixed band 4, bracket 5 fixed by thermopair, thermopair pallet 6, thermopair stationary fixture 7, adjustable disc height pillar 8, described fixed base plate 1 is provided with guide rail 3, skateboarding 2 is installed on guides 3 can slide anteroposterior, described adjustable disc height pillar 8 is with external thread, be arranged on skateboarding 2, described thermopair pallet 6 is provided with tapped through hole, screw thread is arranged on described disc height pillar 8, described thermopair is fixed bracket 5 and is integrated with thermopair pallet 6, described test side fixed band 4 is positioned at thermopair to be fixed bracket 5 place and plays stationary heat couple action, described thermopair pallet 6 is provided with thermopair stationary fixture 7, play stationary heat couple action.
The beneficial effects of the utility model:
Apply this utility model instrument, can be good at, in calibrating thermopair process, to the device that thermopair and standard provide a holding position constant, reducing the damage to standard, improving the accuracy measuring thermopair further.
Accompanying drawing explanation
Fig. 1 is structural principle schematic diagram of the present utility model.
Embodiment
Below the utility model is described in further details.See Fig. 1, its structure of thermocouple calibration stationary installation forms: it fixes bracket 5, thermopair pallet 6, thermopair stationary fixture 7, adjustable disc height pillar 8 by fixed base plate 1, skateboarding 2, guide rail 3, test side fixed band 4, thermopair
Principle of work of the present utility model is:
First thermopair and standard platinum rhodium 10-platinum are carried out binding according to working specification to be placed on tested thermopair and to fix bracket 5, tested thermopair tail end is placed on thermopair pallet 6, and with three points of thermopair stationary fixture 7 stationary heat galvanic couple.By regulating the height of thermopair pallet 6, the lateral separation of adjustment movement slide plate 2, when making thermocouple calibration, standard and tested thermopair are all in geostationary position, thus realize the calibrating of thermopair.
Adopt New-type thermocouple stationary installation, easy to operate, security performance is good, and maintenance cost is low, when avoiding fixing tested thermopair and standard, causes unnecessary damage to standard.Reduce the labour intensity of calibration personnel simultaneously, increase work efficiency.
Concrete operations mode of the present utility model is:
A, draw drawing, make fixed base plate 1 by hand according to figure paper size
B, by hand to skateboarding 2, bracket 5 fixed by thermopair, thermopair pallet 6 carries out processing grooving, holes with drilling machine
C, tested thermopair and standard are installed to thermopair bracket 5, and thermocouple tip is fixed in thermopair pallet 6 position, utilize adjustable disc height pillar 8 to regulate thermopair pallet 6 height.
