Description

A kind of vaccum-pumping equipment of glass liner of thermos

Technical field

The utility model relates to vacuum flask process unit, specially a kind of vaccum-pumping equipment of glass liner of thermos.

Background technique

The reduction of water temperature is exactly scattering and disappearing for heat, and heat scatters and disappears there are three types of approach: 1, heat transfer, for example, glass liner of thermos it Between vacuum layer, exactly prevent from passing to heat in air by heat transfer；2, convection current, as long as being separated with the external world, Such as the plug on vacuum flask, exactly prevent air above hot water convection current and heat is passed in air；3, radiation, is exactly hot Object by infrared radiation dissipated heat, that is, glass liner of thermos silver coating effect, infrared reflection can be gone, without It is that it is allowed to be radiated in air.

The liner of thermos bottle is substantially that bottle is covered in big bottle, and two bottles of mouth seals to form a cavity, is made Cheng Zhonghui is silver-plated on glass liner, and silver nitrate solution is used when silver-plated, and silver nitrate solution is injected into glass liner interlayer, and silver layer plates outside the tank Solution is discharged after plating good silver for layer and outer gallbladder internal layer, and glass liner interlayer contains moisture, it is necessary to dry moisture, after glass liner vacuumizes It could keep the temperature.

Glass liner of thermos heat preservation key point be to have to vacuum in interlayer, more vacuum refill heat preservation degree is better, vacuumizes Air in an interlayer is sought to pump.While vacuumizing, glass liner also needs to heat.Traditional vacuum evacuation device is often being taken out Ideal effect is not achieved in the degree of vacuum, while temperature control is also not so stable, causes qualification rate very poor.
