Abstract
The utility model relates to a thermocouple with standard general temperature. The utility model is characterized in that a shell is formed by combining with two halves; filaments are movable and detachable; the two halves of the shell are fixed by being connected with a steel sheet and a moving-proof fixing assembly. The utility model solves a technological difficult problem of which detection of the existing thermocouple with general temperature can not directly follow a detection regulation of the national thermocouple to carry out a value transferring in laws, and the utility model provides a measure assurance of the value transferring in the laws for industries and companies which use the thermocouple with the general temperature.
Description
The utility model relates to a kind of aeronautical product manufacturing and repairing trades of being used for and carries out the standard stagnation temperature thermopair that transmission of quantity value detects according to national thermocouple calibration rules.
At present, the detection of China's the sector stagnation temperature thermopair has two kinds of methods, and a kind of method is the detection of single-point stagnation temperature thermopair, and it is that tested idol and the supporting back of secondary instrument are directly contrasted calibrating with (S type) second-class standard idol in the crucible type resistance furnace.The defective of this method is the thermo wires material of two kinds of galvanic couples, shape, structure is different fully, their thermal capacity is also fully different with heat transfer rate, so they are also different to the reaction velocity that furnace temperature changes, add other reason, so the temperature in the unit clamp hole at two kinds of thermopair places is also just different.And then the temperature that two kinds of thermopairs record also just has difference.Another prescribing method is the detection of multiple spot stagnation temperature thermopair, for example number of patent application is 94211005 the small-sized standard stagnation temperature of aeromotor thermopair calibration equipment, particular criteria device it and tested shape, structure and thermo wires material in this device are identical, but particular criteria device itself can't carry out transmission of quantity value according to national thermocouple calibration rules in accordance with the law.
The purpose of this utility model provides a kind of standard stagnation temperature thermopair that can directly in accordance with the law carry out transmission of quantity value according to national thermocouple calibration rules, for all industries and the unit that uses stagnation temperature thermopair (single-point and multiple spot) provides the metering of carrying out transmission of quantity value guarantee in accordance with the law.
The purpose of this utility model is achieved in that a kind of standard stagnation temperature thermopair, comprises shell and the location plate washer that is connected as a single entity with it, anti-moving fixation kit and thermo wires, and it is characterized in that: shell is combined by two halves, and thermo wires is movable dismountable; All be filled with thermal cement in the two halves of shell, there is a groove centre, places thermo wires in the groove, and the two halves of shell are fixed by connection steel disc and anti-moving fixation kit.
The purpose of this utility model also can be achieved like this: connect steel disc by screw retention on the plate washer of the location of shell.
The utility model has solved the present stagnation temperature thermopair of China's the sector and has detected the technical barrier that can not directly in accordance with the law carry out transmission of quantity value according to national thermocouple calibration rules, ensures for the unit that uses the stagnation temperature thermopair provides metering.
Elaborate below in conjunction with accompanying drawing:
Fig. 1 the utility model structural representation
Fig. 2 splits back the utility model structural representation (being placed with thermo wires)
Fig. 3 splits back the utility model structural representation (removal thermo wires)
The utility model standard stagnation temperature thermopair is made up of shell 1 and the location plate washer 2 that is connected as a single entity with it, anti-moving fixation kit 3 and thermo wires 4 etc., shell 1 is combined by two halves, thermo wires 4 is movable dismountable, all be filled with thermal cement in the two halves of shell 1, there is a groove centre, place thermo wires 4 in the groove, the two halves of shell 1 are fixing by connection steel disc 5 and anti-moving fixation kit 3.Connect steel disc 5 by screw retention on the location of shell plate washer 2.
The stagnation temperature thermopair that the utility model can solve various models, specification carries out the problem of transmission of quantity value in accordance with the law according to national thermocouple calibration rules.Its shape, structure, thermo wires material and enclosure material can manufacture with the stagnation temperature thermopair of various models, specification identical.Gordian technique is its dismounting easily, thermo wires (bare thermopair) can be taken out after promptly taking apart carry out the error amount that transmission of quantity value obtains each serviceability temperature point of stagnation temperature thermopair in accordance with the law according to national thermocouple calibration rules, then, be assembled into the crucible electrical resistance furnace that standard stagnation temperature thermopair of the present utility model puts into unit clamp with the tested stagnation temperature thermopair of same model, specification and carry out verification, can draw the modified value of tested stagnation temperature thermopair at each serviceability temperature point, problem is resolved.
