Embodiment Construction

[0008] Describe below in conjunction with accompanying drawing and its embodiment, but protection scope of the present invention is not limited to accompanying drawing and its embodiment

[0009] Example.

[0010] like figure 1 and Fig. 2, the glass Dewar / throttling refrigerator assembly provided by the present invention is composed of a metal shell 4, a support pad 8, a glass Dewar 3, a throttling refrigerator 9, a throttling air pipeline 6, a metal cover plate 5, a tight It is composed of parts such as fastening screw 1.

[0011] The glass Dewar 3 is coupled with the throttling refrigerator 9 through the glass Dewar inner tube 7, and the coupling gap is appropriate. According to the different outer diameters of the selected throttling refrigerator 9, the inner diameter of the glass Dewar inner tube 7 should match it, and the matching clearance should meet the matching requirements; the gas to be detected enters the throttling refrigerator through the throttling gas pipelin...
