Description
Technical field
The utility model is related to a kind of peep hole glass, and in particular to a kind of observation for material situation in inspection box body
Aperture apparatus.
Background technology
All it is to use from its charge door mostly, to behaviour due to the existing observation to the internal material situation of case (tank)
Make more time-consuming for personnel, the situation of material in tank can not be found in time, operating personnel are made troubles.In order to
Solve the above problems, technical staff have developed a kind of peep hole for being easily installed and changing.
The content of the invention
Goal of the invention of the present utility model is to provide a kind of observation aperture apparatus, and mainly solving can not observe in the prior art
The problem of box house material situation.
The technical scheme that the utility model solves the above problems is as follows：The observation aperture apparatus provided, including mounting flange,
Peep hole glass and gland flange；The mounting flange is fixed on the through hole of box body wall, and observation is disposed with from inside to outside
Hole glass and gland flange；The gland flange is fixed by screw with mounting flange；The inner side bevel angle α of the mounting flange is big
In the angle of repose of filled material.
O-ring seal is provided between above-mentioned mounting flange and peep hole glass.
The thickness of above-mentioned peep hole glass is preferably greater than or equal to 4mm.
The thickness of above-mentioned mounting flange is more than or equal to 8mm, so as to ensure that the intensity of mounting flange.
Above-mentioned mounting flange is integrated with welding box body.
The pit for detaining peep hole glass is provided with above-mentioned mounting flange and gland flange, whole device is added
Sealing property.
Advantage of the present utility model：
The utility model is using O-ring seal and is provided with the pit matched with peep hole glass so that whole device
Sealing is guaranteed；It is simple in construction, it is easy for installation, it is conveniently replaceable, sealing is reliable.
Brief description of the drawings
Fig. 1 is sectional view of the present utility model；
Fig. 2 is front view of the present utility model.
Reference is detailed as follows：
1- mounting flanges；2- peep hole glass；3- gland flanges.
Embodiment
The utility model is described in detail with reference to Figure of description：
Observation aperture apparatus as shown in Figure 1 is to include mounting flange 1, peep hole glass 2 and gland flange 3.Mounting flange 1
The through hole of box body wall is fixed on, general mounting flange 1 is integrated with welding box body.Casing through hole is disposed with from inside to outside
Mounting flange 1, peep hole glass 2 and gland flange 3, gland flange 3 are fixed by screw with mounting flange 1, mounting flange 1
Inner side bevel angle α is more than the angle of repose for filling material, prevents material from being accumulated in device interior step, influences observing effect.
It is provided with O-ring seal, mounting flange 1 and gland flange 3 and sets between mounting flange 1 and peep hole glass 2
Have for detaining the pit of peep hole glass, so as to ensure that the sealing of the present apparatus.Meanwhile, the thickness of peep hole glass 2 is big
In or equal to 4mm, mounting flange should have certain rigidity, and its thickness should be greater than or equal to 8mm, add whole device
Intensity.
In addition, the side wall, top surface and bottom surface of case (tank) body are provided with multiple observation aperture apparatus, it is easy to the internal thing of case (tank)
The comprehensive observation of material.According to the temperature of the internal different material of case (tank) the flange material different with acid-base property corresponding selection and sight
Examine the material of hole glass.
