Abstract
The utility model relates to an armored thermocouple, in particular to a wear-resistant armored thermocouple, aiming at solving the problems that the wear resistance is poor and the service life is short when the existing armored thermocouple is used because the external part of the existing thermocouple has no wear-resistant protective sleeve. The wear-resistant armored thermocouple comprises a first ceramic sleeve, an armored thermocouple, an adhesive layer and a plurality of second ceramic sleeves. A counter bore is arranged at one end of the first ceramic sleeve. A thermocouple installation hole is arranged at the other end of the first ceramic sleeve. The counter bore is communicated with the thermocouple installation hole. The diameter of the counter bore is larger than the diameter of the thermocouple installation hole. The front end of the armored thermocouple penetrates through the thermocouple installation hole and is arranged in the counter bore. The rear end of the armored thermocouple penetrates through the second ceramic sleeves and is arranged outside the second ceramic sleeves. The adhesive layer is arranged between the first ceramic sleeve and the armored thermocouple. The wear-resistant armored thermocouple is used for measuring the temperature of the high-temperature dust-containing flue gas (medium) of boilers.
Description
Technical field
The utility model relates to a kind of armoured thermocouple.
Background technology
At present; the armoured thermocouple that the industry thermometric uses mainly is made of protection tube, two even cores and magnesium oxide bisque; this thermopair stable performance; but the armoured thermocouple diameter is little; the wall thickness of protection tube is very thin, has only 0.34mm～0.50mm, so just causes the thermopair heatproof not wear-resisting; serviceable life is short, is not suitable for using requiring in the wear-resisting particular surroundings.
The utility model content
The purpose of this utility model is for the outside that solves existing armoured thermocouple does not have the wear-resistant protection cover, and the problem of during use, wear no resistance, the life-span is short provides a kind of wear-resisting armoured thermocouple.
The utility model comprises first porcelain bushing, armoured thermocouple, glue-line and several second porcelain bushings, one end of first porcelain bushing is provided with counterbore, the other end of first porcelain bushing is provided with the thermopair mounting hole, counterbore communicates with the thermopair mounting hole, and the aperture of counterbore is greater than the aperture of thermopair mounting hole, the front end of armoured thermocouple passes the thermopair mounting hole and is arranged in the counterbore, the outside that several second porcelain bushings are arranged on second porcelain bushing is passed in the rear end of armoured thermocouple, is provided with glue-line between first porcelain bushing and the armoured thermocouple.
The utlity model has following beneficial effect: one, the utility model is equipped with first porcelain bushing and several second porcelain bushings in measuring junction (front end) and working end (rear end) of armoured thermocouple, because ceramic pipe has high temperature resistant, wear-resisting characteristic, thereby, make that armoured thermocouple of the present utility model is high temperature resistant wear-resisting again, thereby prolonged the serviceable life of armoured thermocouple greatly.Two, reasonable in design, simple in structure, the easy operating of the utility model, reliable operation.
Description of drawings
Fig. 1 is one-piece construction master's cut-open view of the present utility model.
Embodiment
Embodiment one: present embodiment is described in conjunction with Fig. 1, present embodiment comprises first porcelain bushing 1, armoured thermocouple 3, glue-line 4 and several second porcelain bushings 2, one end of first porcelain bushing 1 is provided with counterbore 1-1, the other end of first porcelain bushing 1 is provided with thermopair mounting hole 1-2, counterbore 1-1 communicates with thermopair mounting hole 1-2, and the aperture of counterbore 1-1 is greater than the aperture of thermopair mounting hole 1-2, the front end of armoured thermocouple 3 passes thermopair mounting hole 1-2 and is arranged in the counterbore 1-1, the outside that several second porcelain bushings 2 are arranged on second porcelain bushing 2 is passed in the rear end of armoured thermocouple 3, is provided with glue-line 4 between first porcelain bushing 1 and the armoured thermocouple 3.Glue-line 4 is selected inorganic high-temp glue for use.Glue-line 4 makes win porcelain bushing 1 and armoured thermocouple 3 firm bonding together.The quantity of second porcelain bushing 2 is determined according to the length of armoured thermocouple.
Embodiment two: in conjunction with Fig. 1 present embodiment is described, present embodiment and embodiment one are different is that it also increases centring ring 5 is arranged, and centring ring 5 is sleeved on the armoured thermocouple 3 and is positioned at first porcelain bushing 1 of glue-line 4 rear ends.When the outside surface of armoured thermocouple 3 was rough, centring ring 5 played the effect that replenishes sizing.Other composition and annexation are identical with embodiment one.
Embodiment three: in conjunction with Fig. 1 present embodiment is described, the length of each of present embodiment second porcelain bushing 2 is 8mm～12mm.Design can keep the flexibility of armoured thermocouple 3 like this.Other composition and annexation are identical with embodiment one or two.
Embodiment four: the length of each of present embodiment second porcelain bushing 2 is 10mm.Design can keep the flexibility of armoured thermocouple 3 like this.Other composition and annexation are identical with embodiment three.
