Abstract
The utility model discloses a thermocouple with pairs of couple wires, which mainly comprises a protective sleeve, the pairs of couple wires and a junction box. One end of a plurality of positive-pole couple wires is arrayed in parallel and closely welded together so as to form a synthetic positive pole; similarly, one end of a plurality of negative-pole couple wires is arrayed in parallel and closely welded together so as to form a synthetic negative pole; then, the synthetic positive and negative poles are butt-welded together so as to form a couple with pairs of couple structures; high-temperature endurable insulating materials are respectively sheathed on the couple wires so as to prevent mutual short-circuit; the ready-made couple is inserted into the protective sleeve and the other ends of the couple wires are respectively connected on a wire connecting terminal of the junction box. Therefore, the pairs of couples can output groups of measuring signals. The service life of the thermocouple can be greatly prolonged.
Description
Technical field
The utility model belongs to sensor, is specifically related to a kind of thermopair that has many to thermo wires.
Background technology
At present, the thermopair of using at industrial circles such as metallurgy, chemical industry, power plant mainly is to be made of protective casing, a pair of galvanic couple silk and a terminal box, can only export one group of measuring-signal.
Because conventional thermopair has only a pair of galvanic couple silk, the common cause that in use damages is that the thermo wires fault causes, as long as one of them damage or fracture of wire just can not be exported temperature signal accurately, causes thermopair to be scrapped.Thereby one be the waste that causes resource, and promptly protective casing and terminal box are not damaged use value in addition, but damage discarded in the lump because of its internal electrical thermo wires; The 2nd, change a thermopair and will spend and purchase and installation cost; The 3rd, damage if be used for the thermopair of the temperature parameter of observing and controlling key, will influence safety in production, and then influence even the technological process of interruption whole production, cause greater loss, especially for modern enterprise, the production line work rhythm is very fast, and the time is exactly benefit.
The utility model content
The purpose of this utility model is to provide a kind of thermopair that has many to thermo wires, to address the above problem.
The technical solution of the utility model is: a kind of thermopair that has many to thermo wires, it mainly comprises protective casing, and is many to thermo wires, terminal box.One of a plurality of anodal thermo wires are held the row arrangement level with both hands and are closely welded together; constitute a synthetic positive electrode; one of same a plurality of negative pole thermo wires are held the row arrangement level with both hands and are closely welded together; constitute a synthetic negative electrode; just will synthesize again; negative electrode is to welded together; make and have many galvanic couples the galvanic couple structure; each is to temperature unanimity of galvanic couple measurement like this; put high-temperature insulation material respectively for each thermo wires; prevent short circuit each other, ready-made galvanic couple is inserted protective casing, the other end of each thermo wires is connected respectively on the connection terminal of terminal box; like this, the many measuring-signals that can export many groups to thermo wires.
The beneficial effects of the utility model, the one, many thermopairs to thermo wires can provide many groups measuring-signal of output simultaneously, and they can backup each other; The 2nd, the exportable many group measuring-signals of each thermopair.Like this, a thermo wires damages, and can directly not cause thermopair to be scrapped, and the thermo wires of other groups can also be exported measuring-signal, can switch use mutually.Therefore prolong the serviceable life of thermopair greatly, provided cost savings greatly and the time, improved whole production control system safe reliability, ensured that production line normally moves, promoted enterprise's increasing production and practising economy.
Be example with thermopair below with two pairs of thermo wires; be specifically described: one of two anodal thermo wires are held the row arrangement level with both hands and are closely welded together; constitute a synthetic positive electrode; one of same two negative pole thermo wires are held the row arrangement level with both hands and are closely welded together; constitute a synthetic negative electrode; just will synthesize again; negative electrode is to welded together; make galvanic couple with four pairs of galvanic couple structures; put high-temperature insulation material respectively for four thermo wires; prevent short circuit each other, ready-made galvanic couple is inserted protective casing, the other end of four thermo wires is connected respectively on four connection terminals of terminal box; like this, two pairs of thermo wires can be exported four groups measuring-signal.They can backup each other, in case a thermo wires damage, production control system can compare according to several groups of signals, makes judgement, in time switches to the signal end that normal signal and report damage, and can be changed when overhauling next time.
Description of drawings
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is further described in detail.
The thermocouple structure synoptic diagram of two pairs of thermo wires of Fig. 1.
The galvanic couple structural representation of two pairs of thermo wires of Fig. 2.
Embodiment
As shown in Figure 1, 2, the utility model thermopair is mainly by protective casing 1, thermopair installing component 2, and sealed terminal box 3, high-temperature insulation sleeve pipe 4, connection terminal 5, galvanic couple end 6, anodal thermo wires 7 and negative pole thermo wires 8 constitute.At first; according to the thermopair technical requirement; choose preparation galvanic couple silk 7 and 8 each two; holding one of two anodal thermo wires 7 level with both hands the row arrangement closely welds together; constitute a synthetic positive electrode; one of same two negative pole thermo wires 8 are held the row arrangement level with both hands and are closely welded together; constitute a synthetic negative electrode; just will synthesize again; negative electrode is to welded together; make galvanic couple end 6 with four pairs of galvanic couple structures; again high-temperature insulation sleeve pipe 4 is enclosed within respectively on galvanic couple silk 7 and 8; it is isolated mutually; galvanic couple is inserted protective casing 1; galvanic couple silk 7 is connected respectively with the connection terminal 5 of sealed terminal box 3 with 8 output signal end, covers lid at last, promptly constituted a complete thermopair.During use, thermopair can be installed on the equipment under test, by the external compensation cable output signal of connection terminal 5 be connected to measuring and controlling equipment and get final product by installing component 2.
It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
