Abstract
The utility model relates to a combustion flame temperature sensor, comprising two hot electrodes made of nickel-chromium or nisiloy wires belonging to two different alloy materials, a diplopore high-temperature insulating casing tube, a binding post, a high-temperature and heat-conducting protecting tube, nuts and a sheathing, wherein, one end of each of the two hot electrodes is welded together, the joints of the hot electrodes are formed into working ends, and the other end of each of the two hot electrodes is connected with the binding post. The middle part of the two hot electrodes are divided by the diplopore high-temperature insulating casing tube, the outer part of the two hot electrodes is provided with the sheathing, and the heat-conducting protecting tube and the nuts are formed into an entity. The utility model has the advantages that the sensor is designed according to thermoelectric effect on measurement high temperature with accurate temperature measurement, little error, simple structure, convenient operation and long service life, and the sensor is suitable for various high-temperature conditions and effectively monitoring the working condition of a fuel heater.
Description
The utility model relates to a kind of sensor, exactly is about the combustion flame temperature sensor, and this sensor mainly is to be used for monitoring fuel heater or burner igniting and combustion conditions.
At present, the fuel heater of domestic production is divided into manual control and controls two kinds automatically by control mode.Automatically the combustion flame temperature sensor of control fuel heater adopts two kinds of different materials of coefficient of thermal expansion, stretches by temperature sensor and touches microswitch and control.Owing to adopted mechanical switch and relevant gear train,, usually caused The whole control system malfunctioning so the ability of shock resistance, anti-vibration is relatively poor.And external like product sensor adopts light-operated mode, and is owing to reasons such as domestic fuel oil quality and heater structures, inapplicable.
The purpose of this utility model is the deficiency at existing combustion flame temperature sensor, according to the thermoelectric effect phenomenon, a kind of flame temperature sensor that designs in conjunction with the fuel heater specific requirement, this sensor has removed mechanical switch and gear train, makes that it has that volume is little, reliability is high, advantage such as high conformity, high temperature resistant, anti-vibration.Owing to overcome the shortcoming of original sensor, be easier to realize the automatic control of fuel heater, burner.
Task of the present utility model is finished by following technical proposals, combustion flame temperature sensor of the present utility model comprises two thermodes that are made of the alloy material of nickel chromium triangle or two kinds of heterogeneities of nisiloy silk, a diplopore high-temperature insulation sleeve pipe, binding post, heat conduction high temperature protection pipe, nut and sheath; One end of wherein said two thermodes welds together, contact is as the working end, it is the hot junction, the other end is that cold junction then produces thermoelectrical potential, the size of thermoelectrical potential becomes corresponding relation with flame temperature, cold junction is connected to the binding post control system can judge fuel heater igniting and combustion conditions by the perceive heat electromotive force, and fuel heater is implemented control, and fuel heater described here can be automotive fan heater or auto heater; The center section of two thermodes is kept apart by the diplopore insulating sleeve; it is outside with the heat conduction high temperature protection seal of tube; be useful on the nut of assembling at heat conduction high temperature protection cover rear portion, heat conduction high temperature protection pipe and nut are formed one, draw lead and be provided with sheath in its outside on described binding post.During use protection tube is inserted in the fuel heater firing chamber; the high temperature protection pipe end is exposed in the firing chamber, directly contacts with combustion flame or non-direct contact, and sensor of the present utility model is according to the special requirement of fuel heater; do not need compensating wire, overall dimensions is made less.
The utility model has the advantages that it is the sensor that designs and reach measurement high temperature according to the thermoelectric effect phenomenon, its measures that temperature is accurate, error is little, simple in structure, easy to use, the life-span is long, be applicable to the situation of various high temperature, and can monitor the operating mode of fuel heater effectively.
Further describe structure of the present utility model below in conjunction with accompanying drawing, wherein:
Fig. 1 is the structural representation of the sensor of combustion flame temperature of the present utility model.
Now referring to accompanying drawing, 1 is that thermode, 2 is that diplopore high-temperature insulation sleeve pipe, 3 is that binding post, 4 is that high temperature protection pipe, 5 is that nut, 6 is sheath.Combustion flame temperature sensor of the present utility model comprises two thermodes 1 that are made of nickel chromium triangle, nisiloy silk or its similar electrical alloy material; one end of these two thermodes 1 welds together; as shown; the other end is connected in binding post 3; the center section of thermode 1 is kept apart by diplopore high-temperature insulation sleeve pipe 2; it is outside, and this heat conduction high temperature protection pipe 4 is formed one with nut 5 with 4 sealings of heat conduction high temperature protection pipe, and described binding post 3 is drawn lead (not shown) and is provided with sheath 6 in its outside.
