Description

A kind of low pressure test chamber observation window

Technical field

The utility model relates to chamber correlative technology field, specially a kind of low pressure test chamber observation window.

Background technique

The observation window of low pressure test chamber currently on the market is mounted in viewing mask with one block of thick glass of comparison, is used To observe the real-time status of case vivo sample.Easily there is condensation in the glass surface of the observation window of this structure, keeps observation window fuzzy Unclear, tester is unable to the state of institute's test sample in clear view to cabinet, in addition, the heat-insulated effect of the observation window of this structure Fruit is undesirable, and thermal loss is larger, and intensity is small, and service life is short.

Utility model content

The purpose of this utility model is to provide a kind of low pressure test chamber observation windows, to solve the glass of existing observation window Easily there is condensation in glass surface, keeps observation window smudgy, and tester is unable to the shape of institute's test sample in clear view to cabinet State, in addition, existing observation window heat insulation is undesirable, thermal loss is larger, and intensity is small, the short problem of service life.

To achieve the above object, the utility model provides the following technical solutions a kind of low pressure test chamber observation window, including Observation window entirety, the first glass, the second glass, third glass, backing plate, heating film, weather-resistant glue and filler, the observation window are whole Body is provided with the first glass, the second glass and third glass, and the first glass, the seam of the second glass and third glass between any two Gap surrounding is connected by backing plate, and the gap filling between the backing plate and the first glass, the second glass and third glass has weather-proof Glue, and the space between the first glass, the second glass and third glass is filled with filler, first glass and third glass Inner surface pastes heating film.

Preferably, first glass, the second glass and third glass material are disposed as tempered glass.

Preferably, the backing plate material is set as high-low temperature resistant nonmetallic materials.

Preferably, the filler material is set as high pure nitrogen.

Compared with prior art, the utility model has the beneficial effects that the low pressure test chamber viewing glass is by 3 blocks of steel Change glass composition, surrounding backing plate made of special high-low temperature resistant nonmetallic materials connects between any two, and performance is used in each gap Good weather-resistant glue sealing is tight, has good heat insulation, thermal loss is minimum, and the space between each glass is filled with high-purity Nitrogen, makes observation window have good heat insulation, and the inner surface of two blocks of glass inside and outside observation window is pasted heating film, can be had Effect eliminates condensation, guarantee tester can in clear view to cabinet institute's test sample state.
