Embodiment
Special-purpose as shown in Figure 1, 2, 3 thermal source is that a special construction is the dried trap formula verification stove of ∏ type, its top is the rectangular dried trap furnace body 1 in a cross section and processes two gaging holes 6,7 along its length, gaging hole size and tested temperature sensor shape similar (size is greater than 1mm), one of them gaging hole 7 is the mounting hole of ultrashort type thermopair, and another gaging hole 6 is the mounting hole of standard.The first half of the mounting hole 7 of ultrashort type thermopair is milled logical, and a plate 8 is installed in the position of mill off, and is deployed a liftable insulation cover thereon.Insulation cover can be incubated whole trap bodies.
For the uniformity coefficient of the temperature that guarantees gaging hole at trap dolly Nogata to two boiler tubes 4 are arranged, two heat conductive rods 3 are installed in the boiler tube 4, place temperature-control heat couple 2 in the axial center hole of heat conductive rod 3, heat conductive rod 3 outside having heaters and guarantee heat conductive rod 3 and trap at the bottom of the temperature of joint portion can reach 1200 ℃, heat conductive rod 3 is connected and fixed with at the bottom of the trap by pilot pin 5.
Heat conductive rod 3 is a high-temperature alloy material of the same race with trap body 1, and its maximum operation (service) temperature is 1300 ℃.
Because the spatial array position of combined temperature sensor in the form of a ring,, adopt no hard power to adorn the installation method dress sample of formula on the whole for guaranteeing convenient and reliable installation and guaranteeing that composition element is not damaged.
Reverse direction at heat conductive rod 3 is installed sample, by the locus of many combined hot galvanic couples of annular temperature sensor probe special-purpose thermal source is installed.Can earlier a plurality of probes be packed in the gaging hole because its gaging hole top is open type, and then insert plate, cover insulation cover, Access Control and measuring system can be operated.
For the insulation material 11 of the performance need insulation covers such as energy-conservation, miniature, environmental protection of assurance device is 128kg/m for its unit weight of tapetum fibrosum
3, heat resisting temperature is more than 1250 ℃.The insulation material of special-purpose thermal source is its unit weight of fiber brick 300～500kg/m of vacuum filtering shape process
3, heat resisting temperature is 1400 ℃.More than two kinds of materials be all Green Product.
As Fig. 4 is 8 shove charge synoptic diagram: it is that the special-shaped sensor of Φ 5 becomes radioactivity to be distributed on to pass through armoring lead wire on the annulus for the big external diameter of 50mm that combined temperature sensor is 8, the external diameter of verification stove furnace shell is less than the interior ring size 10mm of installing ring, the position of special-purpose thermal source will make the gaging hole of special-shaped sensor overlap with the projection of temperature sensor, isolate with fiber brick 10 between 8 special-purpose thermals source and the furnace shell 1, be fixed on the drop-bottom by heat conductive rod 3 gib screws 9.During installation, after the slip of isothermal block slip lid, detected thermocouple measurement end is placed isothermal block, again the isothermal block slip lid is resetted.Standard platinum rhodium 10-platinum thermocouple is installed in the standard gaging hole in advance, and thermopair special test compensating cable is introduced in the stove by the connector of dedicated temperature sensor.The reference edge of standard couple and tested thermopair is connected with test macro after by the reference edge thermostat.
