Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
Shown in Fig. 1, provided by the utility model for the accurate degree control apparatus under vacuum low-temperature environment, comprising: upper flange 1, middle flange 2, lower flange 3, Level tune assembly 4, supporting component 5 and attemperator.Level tune assembly 4 is arranged between upper flange 1 and middle flange 2, and supporting component 5 is arranged between middle flange 2 and lower flange 3.By regulating the bolt and nut regulating mechanism on Level tune assembly 4, carry out the upper surface levelness of leveling upper flange.
Shown in Fig. 2, Level tune assembly 4 comprises at least three cover bolt and nut regulating mechanisms, and bolt and nut regulating mechanism comprises screw thread bush 6, the bearing 8 of screw rod 7, nut 9, screw jacket dress.Screw rod 7 lower end through middle flange 2 lower surface, nut 9 be arranged on be arranged in flange 2 lower surface screw rod 7 on, bearing 8 be arranged on be arranged in flange 2 upper surface screw rod 7 on.
Shown in Fig. 3, electric heater 10 and thermocouple 11 are pasted in upper flange surface bottom, for temperature control and the thermometric of flange face, are convenient in vacuum thermal test, implement the temperature control to upper flange (interface).
Adopt on multilayer coating structure, middle flange face and screw rod with effectively reduce plain flange and background heat sink between radiation heat transfer.Multilayer appearance is high emissivity black film, product can be projected the radiant heat of coming scatter to very soon test facility heat sink in, reduce support impact that product is dispelled the heat.
Shown in Fig. 4, multilayer is made up of 40um carburizing black film 12,20 layers of thermal insulation layer of 1 floor height emissivity, 1 layer of 25um Kapton 15.Every layer of thermal insulation layer by 1 layer of 20d polyamide fibre silk screen 13 below and above the two-sided aluminized mylar 14 of one deck 6um form.Black film and 25um Kapton sewn by hand are in multilayer.
