Abstract
The invention provides a variable-diameter type armored thermocouple and comprises a thermocouple wire and a protective bushing, wherein, the thermocouple wire is inserted into the protective bushing; the invention is characterized in that the diameter of the measuring end on the front end of the protective bushing is larger than the diameter of the back part of the protective bushing; the transition between the measuring end on the front part of the protective bushing and the back part of the protective bushing is a natural stretching-shaped transition; the diameter of the measuring end on the front part of the thermocouple wire is larger than the diameter of the back part of the thermocouple wire; the transition between the measuring end on the front part of the thermocouple wire and the back part of the thermocouple wire is a natural stretching-shaped transition. The invention is the armored thermocouple with different diameters manufactured in the stretching way and can be used for special application; the measuring end on the front part is larger and can resist higher temperature while having long service life; the back part is thinner and can be arranged in a minor space and the weight for use can be reduced; therefore, the invention is particularly suitable for application in an aircraft.
Description
Technical field
The present invention relates to a kind of armoured thermocouple, particularly relate to measuring junction and the inconsistent reducing type metal-shielding electric thermo-couple of thermopair rear portion diameter on a kind of thermopair front portion, is to the improvement of existing armoured thermocouple structure, belongs to the armoured thermocouple manufacturing technology.
Background technology
Armoured thermocouple comprises insulator, thermocouple wire and protective casing; thermocouple wire inserts in the head protection sleeve pipe of thermopair; temperature by the protective casing measurement environment; prevent that thermocouple wire is damaged, so the environment for use of thermopair mainly is subjected to the restriction of the adaptedness and the measuring condition of thermopair.Domestic existing armoured thermocouple is generally same diameter, and promptly measuring junction is consistent with the reference edge diameter.In the time of need measuring higher temperature in use, need larger-diameter armoured thermocouple, because its diameter is bigger, the crooked difficulty of installing is in military project, scientific research department, owing to be subjected to the restriction of mounting condition, can not use, adopt armoured thermocouple, then because diameter is thinner than minor diameter, life-span will be influential, can not satisfy request for utilization.
Summary of the invention
Purpose of the present invention just is to overcome the prior art above shortcomings, improve by research, provide a kind of reducing type metal-shielding electric thermo-couple, the measuring junction of this reducing type metal-shielding electric thermo-couple and reference edge diameter are inconsistent, have high temperature resistant, corrosion-resistant, the temperature measured accurately and reliably with the characteristics of long service life.
The technical solution that the present invention provides is: this reducing type metal-shielding electric thermo-couple; include thermocouple wire and protective casing; wherein thermocouple wire inserts in the protective casing; be characterized in the diameter of the measuring junction diameter of described protective casing front portion greater than the protective casing rear portion; transition between the measuring junction of protective casing front portion and the protective casing rear portion is the natural transition of drawing and forming; the measuring junction diameter of described thermocouple wire front portion is greater than the diameter at thermocouple wire rear portion, and the transition between the measuring junction of thermocouple wire front portion and the thermocouple wire rear portion is the natural transition of drawing and forming.
Compared with prior art, beneficial effect of the present invention is: adopt stretching mode to be made into the armoured thermocouple of different-diameter, can be used for the use of specific use, anterior measuring junction is thicker, can anti-higher temperature and longer life arranged, the rear portion more carefully can be installed in less space, and can reduce the weight of use, thereby is particularly suitable for using in aircraft.
Description of drawings
Accompanying drawing is the structural representation of the embodiment that provides of the present invention.
Embodiment
Below in conjunction with embodiment concrete technical scheme of the present invention is described further:
As shown in the figure; this reducing type metal-shielding electric thermo-couple; include thermopair electrode 1 and protecting tube 2; wherein thermopair electrode 1 inserts in the protecting tube 2; measuring junction 3 diameters of described protecting tube 2 front portions are greater than the diameter at protecting tube 2 rear portions; transition between the measuring junction 3 of protecting tube 2 front portions and protecting tube 2 rear portions is the natural transition of drawing and forming; measuring junction 4 diameters of described thermopair electrode 1 front portion are greater than the diameter at thermopair electrode 1 rear portion, and the transition between thermopair electrode 1 anterior measuring junction 4 and thermopair electrode 1 rear portion is the natural transition of disposable drawing and forming.
The present invention adopts the armoured thermocouple of the different-diameter that stretching mode is made into, can be used for the use of specific use, anterior measuring junction is thicker, can anti-higher temperature and longer life arranged, the rear portion more carefully can be installed in less space, and can reduce the weight of use, thereby be particularly suitable in aircraft, using.
