Abstract
The utility model discloses an observation window for a plate-turnover valve chamber of a monocrystalline silicon furnace, which comprises a piece of observation glass arranged above the plate-turnover valve chamber, wherein the surface of the observation glass in the plate-turnover valve chamber is plated with a reflective layer, the reflective layer is arranged to be an annular structure, and the middle position of the observation glass is reserved with a transparent and oval-structured observation small window. The surface of the observation glass in the plate-turnover valve chamber is plated with the reflective layer, and the middle of the observation glass is reserved with the transparent observation small window, thereby having observation effect, and simultaneously avoiding loss of sealing effect of a rubber sealing ring caused by overheat by utilizing the reflective layer to reflect radiant heat in the furnace, and the rubber sealing ring is contacted with the observation glass. The observation window for the plate-turnover valve chamber of the monocrystalline silicon furnace is not only simple in structure and easy to realize, but also convenient to mount, and safety and reliability are high.
Description
Technical field
The utility model relates to monocrystal stove turnover panel valve chamber, relates in particular to a kind of monocrystal stove turnover panel valve chamber viewing window.
Background technology
Monocrystal stove furnace chamber part is by the main chamber, and turnover panel valve chamber and concubine are formed.The turnover panel valve chamber plays UNICOM and partition effect between main chamber and concubine.All to pass through the turnover panel valve chamber in crystal growth with when getting crystal bar,, when furnace high-temperature, make this viewing window heating because thermal radiation absorbs so it has a viewing window.Contacted with it rubber seal is understood overheated and is lost sealing function, has two schemes to address this problem usually: the one, adopt double-deck (quartz) glass, middle water-cooled.In case it is broken that its shortcoming is a glass, it is indoor that water can pour in High Temperature Furnaces Heating Apparatus, shines into potential safety hazard.Structure design is installed all more complicated in addition.The 2nd, adopt the individual layer silica glass.Overheated in order to reduce, window size is reduced a lot.Advantage is simple in structure, and shortcoming is that the visual field is too little, observes operation inconvenience.
The utility model content
The purpose of this utility model is to provide a kind of monocrystal stove turnover panel valve chamber viewing window, and it has simple in structure, easy for installation and characteristics that safe reliability is high.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of monocrystal stove turnover panel valve chamber viewing window, it comprises the sight glass that is installed on the turnover panel valve chamber, wherein, described sight glass is positioned on the indoor surface of turnover panel valve chamber and is coated with reflector layer.
Especially, described reflector layer is set to ring structure, leaves transparent observation fenestella in the mid-way of sight glass.
Especially, described sight glass is a silica glass, and described reflector layer is the metallic membrane with reflective characteristic.
Especially, described observation fenestella is oval or oblong any structure.
The beneficial effects of the utility model are, the sight glass of described monocrystal stove turnover panel valve chamber viewing window is positioned on the indoor surface of turnover panel valve chamber and is coated with the annular reflector layer, and leave transparent observation fenestella in the centre, when playing observing effect, utilize the radiations heat energy in the reflector layer reflection loss of sheet, the glue sealing-ring of having avoided contact with sight glass is understood overheated and is lost sealing function, not only simple in structure, be easy to realize, and easy for installation, the safe reliability height.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structural representation of the utility model monocrystal stove turnover panel valve chamber viewing window.
Among the figure:
1, sight glass; 2, reflector layer; 3, observe fenestella.
Embodiment
Please refer to shown in Figure 1, Fig. 1 is the structural representation of the utility model monocrystal stove turnover panel valve chamber viewing window, in present embodiment, a kind of monocrystal stove turnover panel valve chamber viewing window, it comprises the sight glass 1 that is installed on the turnover panel valve chamber, described sight glass 1 is a silica glass, and described sight glass 1 is positioned on the indoor surface of turnover panel valve chamber and is coated with reflector layer 2, the golden film of described reflector layer 2 for having reflective characteristic, be set to ring structure, and leave the observation fenestella 3 of transparent ellipsoidal structure in the mid-way of sight glass 1.Described observation fenestella 3 is used for indoor situation is observed, and utilizes the radiations heat energy in the reflector layer 2 reflection losss of sheet, and the glue sealing-ring of having avoided contact with sight glass is understood overheated and lost sealing function, not only simple in structure, be easy to realize, and easy for installation, the safe reliability height.
Above embodiment has just set forth ultimate principle of the present utility model and characteristic, can along with the shape of reflector layer and observe fenestella shape change and change.The utility model is not limited by above-mentioned example, and under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various variations and change, and these variations and change all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
