Detailed description of the invention
Fig. 1 is the overlooking structure diagram of specific embodiment one；
Fig. 2 is the side structure schematic view of specific embodiment one.
Specific embodiment
For the technical solution and working principle that the present invention is furture elucidated, with reference to the accompanying drawing with specific embodiment to this
Invention is described further.
Embodiment one:
A kind of temperature standard device of smokeless environment-friendly, for the detection to temperature sensor.The temperature standard device
Chief component is oil groove, and the oil groove is square groove, and middle part is equipped with inner cavity 4, the middle part of top surface cell wall, equipped with using respectively
In two jacks for placing standard temperature sensor and temperature sensor to be detected, standard temperature sensor and testing temperature to be checked are passed
The temperature module (probe in other words) of sensor is probeed into oil groove inner cavity 4 by the jack.
The surrounding cell wall of the oil groove is equipped with heating layer 9 and insulating layer (not shown), and insulating layer covers the outer of heating layer 9
Surface, the heating layer 9 is interior to be equipped with closed oil pocket, and is equipped with the pressure relief valve 10 connecting with oil pocket.The oil pocket from
Outside surrounds oil groove inner cavity, and the inside of the oil pocket is equipped with two heating rods 1 in left and right and heating rod 2, as shown in Figure 1, two add
Hot pin is connected by the conducting wire of interior high temperature and the power-supply device outside oil groove.It is filled in oil pocket full heat medium (silicone oil), it is described
Heat medium, in oily cavity circulation, is conducive to the uniformity for improving temperature measuring area temperature by the driving of internal circulation pump 3.It is followed in described
Immersible pump can be used in ring pump 3, is arranged inside oil pocket, or position is arranged near oil groove outside in internal circulation pump, with package
The relatively nipple road of thermal insulation material is connected to oil pocket, reduces scattering and disappearing for heat.
The inner cavity 4 of the oil groove upper and lower, left and right be respectively equipped with one it is calibrated after reference temperature(TR) sensor (5,6,7,
8), the signal output end of four above-mentioned reference temperature(TR) sensors and the observation device outside oil groove connect.Four reference temperature(TR)s
The medium position of sensor is used for temperature measuring area.
Working principle:
Standard temperature sensor 14 and temperature sensor to be detected 13 are mounted on the oil groove by jack, such as Fig. 2
Shown, the temperature module of standard temperature sensor 14 reaches the position in standard temperature sensor thermometric region 12, testing temperature to be checked
The temperature module of sensor 13 reaches the position in temperature sensor thermometric to be checked region 11.Standard temperature sensor 14 and to be detected
The signal output end of temperature sensor 13 is connect with external observation device, and control heating rod 1 and 2 works, and makes adding in oil pocket
Thermal medium heating, the air themperature for improving oil groove inner cavity 4 are specified to expected with temperature, as four be arranged in oil groove inner cavity 4
The registration of a reference temperature(TR) sensor is consistent or relative error is when less than 0.2 DEG C, i.e., after the ambient temperature-stable of temperature measuring area, i.e.,
Work can be measured, or necessary amendment first is carried out to above-mentioned error amount, then starts to measure work, reads normal temperature sensing
The measured value of device 14 and temperature sensor to be detected 13 judges that the reading of temperature sensor 13 to be detected whether there is error, if
There are errors, place under repair and adjust to product.
In order to avoid heating layer expanded by heating causes pressure to increase initiation accident, pressure relief valve has been installed additional in heating layer
10, when pressure is more than scheduled setting pressure, pressure relief valve 10 can be automatically turned on and be released stress, when pressure is less than setting value
Pressure relief valve 10 ends afterwards.Since temperature sensor 13 to be detected is not of uniform size, may not necessarily be matched just with corresponding jack,
It can be by adhesive plaster resistant to high temperature by the gap closing between sensor and jack.
In this implementation, heating layer seals and fills silicone oil, and heating layer temperature is transferred to oil groove inner cavity by logical heat transfer,
So that the thermal field of oil groove inner cavity is more uniform, temperature fluctuation range is small, compared to the prior art, the working region in oil groove inner cavity
It can greatly increase.
Embodiment two:
On the basis of example 1, the present embodiment standard set-up has additional outer circulation pump (not shown), and oil pocket passes through institute
It states outer circulation pump and circulation line to connect with the heat exchange equipment outside oil groove, the heat medium after making heating is dropped by heat exchange equipment
Wen Houzai is back in oil pocket, and the circulation line is being respectively equipped with control valve close to the position of oil pocket outlet and entrance, makes oil
When heated, heat medium is not enclosed with thermal insulating material in oil groove flows outside, and outside the control valve and circulation line to chamber
Material.
After standard set-up completes detection work, since the setting of insulating layer cannot cool down in time, therefore pumped by outer circulation
Heat medium is imported into heat exchange equipment, is cooled down for it, while utilization is collected to thermal energy.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, the present invention
Claimed range is delineated by the appended claims, the specification and equivalents thereof from the appended claims.
