Abstract
The utility model relates to the technical field of an armored thermocouple and especially relates to a dual-wire armored thermocouple. The dual-wire armored thermocouple comprises a stainless steel sleeve tube and magnesium oxide. Two thermocouple wires, respectively a first thermocouple wire and a second thermocouple wire, are arranged inside the stainless steel sleeve tube. The magnesium oxide is filled between the inner wall of the stainless steel sleeve tube and the thermocouple wires. The first thermocouple wire has a circular cross section, and the second thermocouple wire has a rectangular cross section. When using the dual-wire armored thermocouple, a user can measure respectively through the two thermocouple wires to avoid a measurement failure caused by faults of a single thermocouple wire, so that the user can continue to the dual-wire armored thermocouple and also daily maintenance for equipment can be achieved conveniently. The dual-wire armored thermocouple has the advantages of a simple structure, reasonable arrangement, low manufacture cost and the like.
Description
Technical field
The utility model relates to the armoured thermocouple technical field, particularly a kind of two armoured thermocouples.
Background technology
Armoured thermocouple is as sensor for measuring temperature, common and temperature transmitter, regulator and Displaying Meter etc. support the use, the anabolic process control system is in order to direct measurement or control in various production runes fluid, steam and gas medium and solid surface equitemperature in 0-1800 ℃ of scope.Therefore many advantages such as armour shape thermopair has can be crooked, high pressure resistant, thermal response time is fast and sturdy and durable are widely applied in all trades and professions, and as the sensor of measuring temperature, common and Displaying Meter, recorder and electronic controller support the use.Popular armoured thermocouple is single type in the market, so the maintenance of just must stopping in case thermocouple wire breaks down brings very large inconvenience to the user.Therefore be necessary existing armoured thermocouple structure is carried out technical renovation further.
The utility model content
The purpose of this utility model is for the defective of prior art and deficiency, provides a kind of simple in structure, two armoured thermocouples reasonable in design, easy to use.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of two armoured thermocouples described in the utility model, comprise stainless steel sleeve pipe and magnesium oxide, be provided with two thermocouple wires in described stainless steel sleeve pipe, two thermocouple wires are respectively a thermocouple wire and No. two thermocouple wires, described magnesium oxide is filled between stainless steel sleeve inside pipe wall and thermocouple wire, the rounded shape of the xsect of a described thermocouple wire, the rectangular shape of the xsect of described No. two thermocouple wires.
Further, described stainless steel sleeve pipe outer wall is disposed with prime coat and anticorrosive coat from inside to outside, and the thickness of described prime coat is 15～25 microns, and the thickness of described anticorrosive coat is 23～33 microns.
After adopting said structure, the utility model beneficial effect is: a kind of two armoured thermocouples described in the utility model, comprise stainless steel sleeve pipe and magnesium oxide, be provided with two thermocouple wires in described stainless steel sleeve pipe, two thermocouple wires are respectively a thermocouple wire and No. two thermocouple wires, described magnesium oxide is filled between stainless steel sleeve inside pipe wall and thermocouple wire, the rounded shape of the xsect of a described thermocouple wire, the rectangular shape of the xsect of described No. two thermocouple wires.When using the utility model, measure respectively by two thermocouple wires, avoided in the past single fault to occur and immeasurable phenomenon is convenient to the successional use of user, also be convenient to the maintenance of everyday devices simultaneously.The utlity model has simple in structurely, arrange rationally, the advantage such as cost of manufacture is low.
Description of drawings
Accompanying drawing described herein is to be used to provide further understanding of the present utility model, consists of the application's a part, but does not consist of to improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A cut-open view in Fig. 1;
Description of reference numerals:
1, stainless steel sleeve pipe; 2, magnesium oxide; 3, thermocouple wire; 4, No. two thermocouple wires; 5, prime coat; 6, anticorrosive coat.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, illustrative examples wherein and explanation only are used for explaining the utility model, but not as to restriction of the present utility model.
As shown in Figure 1 and Figure 2, a kind of two armoured thermocouples described in the utility model, comprise stainless steel sleeve pipe 1 and magnesium oxide 2, be provided with two thermocouple wires in described stainless steel sleeve pipe 1, two thermocouple wires are respectively a thermocouple wire 3 and No. two thermocouple wires 4, described magnesium oxide 2 is filled between stainless steel sleeve pipe 1 inwall and thermocouple wire, the rounded shape of the xsect of a described thermocouple wire 3, the rectangular shape of the xsect of described No. two thermocouple wires 4; The thermocouple wire of different profiles can easily be identified when both having facilitated the production assembling, also can facilitate the ordinary maintenance maintenance.
As a kind of optimal way of the present utility model, described stainless steel sleeve pipe 1 outer wall is disposed with prime coat 5 and anticorrosive coat 6 from inside to outside, and the effect of prime coat 5 is the adhesion that strengthens anticorrosive coat 6; The thickness of described prime coat 5 is 15～25 microns, and the thickness of described anticorrosive coat 6 is 23～33 microns.The erosion resistance of stainless steel sleeve pipe 1 can be improved like this, the serviceable life of thermopair can be effectively extended.
During with the utility model thermometric, not only can avoid in the past single fault to occur and immeasurable phenomenon, also can improve the erosion resistance of stainless steel sleeve pipe, can effectively extend the serviceable life of thermopair.In addition, this is simple in structure, reasonable in design, low cost of manufacture.
The above is only better embodiment of the present utility model, therefore all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
