The specific embodiment
An embodiment of the present utility model as shown in Figure 1, its body skin 1 and compound lid all adopt the stainless steel material manufacturing, the brass material manufacturing of inner housing 4 usefulness 2 millimeters thick.Wherein shut after the vacuum pumping between the double wall of body skin, to guarantee its heat preservation effect.On the inwall of body skin 1 end opening, make negative thread, and make outside thread (referring to accompanying drawing 2), and pay by screw thread body skin 1 and inner housing 4 and compound lid are linked together in the upper end open of inner housing 4.One through hole is arranged in the middle of the compound lid flange 6, forms the pipeline with inner housing 4 internal communication, and on this section pipeline with one section pipe of screw thread, and fixedly vacuum valve 8 and vacuum manometer 7 thereon.The used vacuum valve of present embodiment is a threeway vacuum needle-valve.The pipe 10 that links to each other with the vacuum valve extracting vacuum that can link to each other with vacuum also can link to each other with institute's pump, gives pressurization in the inner housing 4.Be provided with the heating tape 2 of annular in the body skin 1 of present embodiment and the space between the inner housing 4, and heating tape 2 required electric power introduced in it, so constitute the device that changes system temperature by being located at the compound lead-in wire that covers 16.By going between 5 with temperature element, as thermocouple, measured temperature signal extracts simultaneously.In inner housing, also be provided with the thermocouple that is used for thermometric, but all not expressions in the drawings.In addition, also be provided with second connecting pipeline 11 that is communicated with the space between the inner and outer shell, on pipeline 11, also be provided with valve compound covering.Second pipeline 11 can have following several purposes: the first in use links to each other it with vacuum pump, makes its inside that certain degree of vacuum be arranged, and this can further improve the heat-insulating property of apparatus; Its two be space between inner and outer shell be under the antivacuum state and need be to system's heating so that when keeping certain temperature in the sample storeroom, open the valve of pipe 11 slightly, make heating cause gas to expand and be released, prevent accident; It three is samples that requirement is stored when preserving at low temperatures, can charge into cooling media in 11 interlayers that form cool off between inner and outer shell by managing, as charge into media such as cool brine or liquid nitrogen.From figure, be also shown in addition, be equipped with the insulated enclosure pad in the connection place of compound lid and inner and outer shell.
Its outer dia of apparatus by a reality of the structure manufacturing of accompanying drawing 1 is 155 millimeters, and the gap between the double wall of body skin is 10.5 millimeters, and the internal diameter of inner housing is 165 millimeters, highly is 185 millimeters, and the weight of whole apparatus when zero load is 2.8Kg.Obviously this size is very convenient carries, carries and transport.Through the field service test test, the accessible final vacuum in storage sample cell in the inner housing of this charmed embodiment is less than 5 * 10
-2MmH, and the maximum pressure that can carry is 0.80MPa.When adopting annular heating tape structure to heat, its sample storeroom temperature can reach 300 ℃; And when charging into liquid nitrogen between inner and outer shell, sample storeroom temperature can reach-173 ℃.And the apparatus of present embodiment possesses suitable insulating power, after system reaches a preset temperature, close thermal source after, apparatus still keeps original temperature in considerable time under outdoor environment.For example, after the sample cell temperature was heated to 95 ℃, PTO Power Take Off placed 20～25 ℃ of room temperature environments after following 15 hours, and the temperature in its sample cell has only descended 5～8 ℃.In addition, also find,, use vacuum pump (comprise and make vacuum pump by hand) to bleed again, sample is dehydrated to a certain extent from managing 10 when plant sample being put into the sample storeroom and whole apparatus being assembled through actual test.
Also can make the bigger apparatus of volume for special operating needs by basic thought of the present utility model.And when changing the annular heating tape in the previous embodiment into semiconductor heat booster, can become another embodiment of the present utility model.
