Abstract
The utility model discloses a kind of gasification oven thermocouple, include terminal box, protection tube, the platinum-rhodium wire being placed in protection tube, extension, bulb connecting pipe, I shape flange and flange, protection tube is four-layer structure, wherein outermost layer is carborundum tube, middle two layers are respectively alundum tube, and innermost layer is the corundum core of hollow; I shape flange is fixedly connected on the side of flange; The opposite side of flange is fixedly connected with cutting ferrule, and cutting ferrule is connected with terminal box, is provided with the magnetic bead for sealing platinum-rhodium wire in cutting ferrule.The protection tube of four-layer structure of the present utility model at high temperature all can bear the high temperature of 1600 DEG C and keep good impermeability and soundness; The damage that sealing structure can prevent outermost layer carborundum tube is carried out under the cooperation of cutting ferrule with magnetic bead; Bulb connecting pipe and extension can carry out inserting dark adjustment to gasification oven thermocouple; When hazardous medium is revealed at high operating temperatures, the thermocouple structure within alundum tube and shutoff can be extracted in time out.
Description
Technical field
The utility model relates to temperature measuring instrument field, specifically a kind of gasification oven thermocouple.
Background technology
In industrial processes, often need the problem measuring gasification furnace wall temperature.
Thermopair is the detecting element in automation process control system, is a kind of Automation Control Instruments.Thermopair background principle is thermoelectric effect, its phenomenon is when two kinds of heterogeneity metal endpoints are connected to form with closed loop, if having temperature difference between two-end-point, then has electric current between loop and produces, the node that in loop, temperature is higher is called hot junction, and this point is placed in thermometric place usually; Temperature comparatively low side is called cold junction, i.e. the output terminal of thermopair, and its output signal is DC voltage, converts digital signal to by A/D converter, and by software hydrochloric acid, is transformed into actual temperature value.In petrochemical complex, metallurgy and power industry, the application of thermopair is very wide.
Existing gasification oven thermocouple adopts alundum tube; although high temperature resistant; but easily break with during in-site installation in transportation; Drain Resistance device is simultaneously only to prevent ground floor protection tube to break caused leakage; as the second layer breaks, because there is no Drain Resistance device, cause it to external leakage; cause potential safety hazard, Novel gasification furnace electric thermo-couple well solves this problem.
Utility model content
For prior art Problems existing, the purpose of this utility model is to provide a kind of in-site installation and convenient disassembly and the good gasification oven thermocouple of impermeability.
The technical solution of the utility model is as follows:
A kind of gasification oven thermocouple, include terminal box, protection tube, the platinum-rhodium wire being placed in described protection tube, extension, bulb connecting pipe, I shape flange and flange, it is characterized in that: described protection tube is four-layer structure, wherein outermost layer is carborundum tube, middle two layers are respectively alundum tube, and innermost layer is the corundum core of hollow; Described I shape flange is fixedly connected on the side of described flange, the bulb of described bulb connecting pipe is positioned at described flange, the front end of bulb connecting pipe passes from the side of described flange and passes described I shape flange and is connected with one end of described extension, and the other end of described extension is connected with described protection tube; The opposite side of described flange is fixedly connected with cutting ferrule, and described cutting ferrule is connected with described terminal box, is provided with the magnetic bead for sealing described platinum-rhodium wire in cutting ferrule.
Described gasification oven thermocouple, is characterized in that: be provided with lock screw outside described extension.
The beneficial effects of the utility model:
The protection tube of four-layer structure of the present utility model at high temperature all can bear the high temperature of 1600 DEG C and keep good impermeability and soundness; The damage that sealing structure can prevent outermost layer carborundum tube is carried out under the cooperation of cutting ferrule with magnetic bead; Bulb connecting pipe and extension can carry out inserting dark adjustment to gasification oven thermocouple; When hazardous medium is revealed at high operating temperatures, the thermocouple structure within alundum tube and shutoff can be extracted in time out.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
See Fig. 1, a kind of gasification oven thermocouple, include terminal box 1, protection tube 9, the platinum-rhodium wire being placed in protection tube 9, extension 7, bulb connecting pipe 6, I shape flange 5 and flange 4, protection tube 9 is four-layer structure, wherein outermost layer is carborundum tube, middle two layers are respectively alundum tube, and innermost layer is the corundum core of hollow; I shape flange 5 is fixedly connected on the side of flange 4, the bulb of bulb connecting pipe 6 is positioned at flange 4, the front end of bulb connecting pipe 6 passes from the side of flange 4 and passes I shape flange 5 and is connected with one end of extension 7, and the other end of extension 7 is connected with protection tube 9; The opposite side of flange 4 is fixedly connected with cutting ferrule 2, and cutting ferrule 2 is connected with terminal box 1, is provided with the magnetic bead 3 for sealing platinum-rhodium wire in cutting ferrule 2.
In the utility model, lock screw 8 is installed outside extension 7.
