Description
Technical Field
The utility model relates to the technical field of temperature meters, in particular to a novel armored temperature sensor.
Background
The armoured temperature sensor is used for directly measuring or controlling the temperatures of fluid, steam, gas medium, solid surface and the like within the range of 0-1800 ℃ in various production processes, the armoured temperature sensor is commonly applied to detecting the temperature of a boiler furnace, the armoured temperature sensor is generally connected to the wall of the boiler through a flange, the armoured thermocouple stretches into the furnace to detect the temperature, the surface of the armoured thermocouple inevitably accumulates carbon black which is not completely combusted in the furnace, and over time, the sensitivity of the carbon black accumulated on the surface of the armoured thermocouple to the temperature is reduced, so that the temperature detection is inaccurate.
Disclosure of Invention
The utility model provides a novel armored temperature sensor, which aims to solve the problem that the existing armored temperature sensor is inaccurate in detecting the temperature of a boiler hearth.
The technical scheme provided by the utility model is as follows: the utility model provides a novel armor temperature sensor, including the changer, the changer lower part is the heat insulation post, the heat insulation post lower part is the installation flange lid, installation flange lid lower part is the armor thermocouple, the compensation wire of armor thermocouple passes the heat insulation post and connects the changer, a bellows of installation flange lid bottom fixed connection, bellows and installation flange lid form a sealed space and encircle the armor thermocouple in the inside, the bellows is made by bimetal composite metal material, bimetal composite material's two kinds of metal material's thermal expansion rate is different, the inboard surplus space of bellows is filled with the heat conduction cream.
The heat insulation column is provided with radiating fins.
The beneficial effects of the utility model are as follows: the armoured thermocouple is surrounded and is not contacted with flue gas in the hearth, the sensitivity of the detected temperature cannot be changed, and the corrugated pipe is made of two composite metal materials with different thermal expansion coefficients, so that the corrugated pipe can expand and shrink due to the huge temperature difference in the hearth after the boiler is ignited and when the boiler is stopped, carbon black on the outer side of the piled corrugated pipe can be vibrated and fallen, and the corrugated pipe can transmit the real temperature of the hearth.
Drawings
Fig. 1 is a schematic diagram of the structure of the present utility model.
In the figure, the heat-insulating type heat-insulating device comprises a 1-transmitter, a 2-heat-insulating column, a 3-mounting flange cover, a 4-armored thermocouple, a 5-corrugated pipe, 6-heat-conducting paste and 7-heat-radiating fins.
Detailed Description
As shown in FIG. 1, the novel armored temperature sensor comprises a transmitter 1, wherein the lower part of the transmitter 1 is provided with a heat insulation column 2, the lower part of the heat insulation column 2 is provided with a mounting flange cover 3, the lower part of the mounting flange cover 3 is provided with an armored thermocouple 4, a compensation wire of the armored thermocouple 4 penetrates through the heat insulation column 2 to be connected with the transmitter 1, the bottom of the mounting flange cover 3 is fixedly connected with a corrugated pipe 5, the corrugated pipe 5 and the mounting flange cover 3 form a sealed space to surround the armored thermocouple 4 inside, the corrugated pipe 5 is made of a bimetal composite metal material, the thermal expansion rates of two metal materials of the bimetal composite material are different, and the residual space on the inner side of the corrugated pipe 5 is filled with heat conducting paste 6.
When the boiler is in operation, the temperature in the hearth is transmitted to the armored thermocouple 4 by the corrugated pipe 5 and the heat conducting paste 6, the armored thermocouple 4 is not contacted with flue gas in the hearth due to being surrounded, the sensitivity of the detected temperature cannot be changed, and the corrugated pipe 5 is made of two composite metal materials with different thermal expansion coefficients, so that the corrugated pipe 5 can expand and contract due to the huge temperature difference in the hearth after the boiler is ignited and when the boiler is stopped, carbon black outside the accumulated corrugated pipe 5 can be vibrated to fall off, and the actual temperature of the hearth can be transmitted by the corrugated pipe 5.
The heat insulation column 2 is provided with a heat dissipation fin 7 for improving heat dissipation strength.
