Abstract
The utility model provides a tungsten-rhenium thermocouple calibrating device. High temperature oxidation resistant heating components pass through a heat insulation layer and a thermal insulation layer and are inserted into the space between a furnace tube and the thermal insulation layer. The furnace tube is provided between the thermal insulation layer and the heat insulation layer. One end of the furnace tube is connected with a vacuum device, and the other end is connected with a calibrated tungsten-rhenium thermocouple. The high temperature oxidation resistant heating components are uniformly distributed along the furnace tube. Two ends of the furnace tube are supported by protective covers and a water cooling device is provided. The technical problems of low using temperature and suitability for use under atmosphere state in prior-art thermocouple calibrating device are settled, and a gap in a thermocouple calibration industry in our country is supplied.
Description
Technical field
The utility model relates to a kind of thermocouple calibration device, and characteristics are the high-temperature vacuum calibratings that are used for Wolfram rhenium heat electric couple.
Background technology
Present thermocouple calibration device all is to use under atmospheric condition, and Supreme Procuratorate's fixed temperature can only arrive 1200 ℃.And Wolfram rhenium heat electric couple and protective casing thereof can only use under vacuum, reduction and protective atmosphere state, and require proving temperature to reach more than 1600 ℃, therefore can not use existing thermocouple calibration device to examine and determine.
Summary of the invention
The purpose of this utility model provides a kind of Wolfram rhenium heat electric couple calibrating installation, to solve the not high and technical matters that adaptation is used of existing thermocouple calibration device serviceability temperature under atmospheric condition.
Be characterized in and using more than 1600 ℃ that the temperature field evenly has vacuum protector and water cooling plant simultaneously.
The technical solution adopted in the utility model is: the resistance to high temperature oxidation heater element passes heat-insulation layer and thermofin inserts between boiler tube and the thermofin, boiler tube is arranged in the middle of thermofin and the heat-insulation layer, boiler tube one end connects vacuum plant, and the other end connects the Wolfram rhenium heat electric couple of being examined and determine.The resistance to high temperature oxidation heater element evenly distributes along boiler tube.The boiler tube two ends are adopted protective cover to support and are had water cooling plant.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
