This invention relates to a viewing window with double tempered glass. Conventional viewing windows were made of a single piece of tempered glass, so if the tempered glass were to break due to internal pressure or external impact, there was a risk that the substances inside would spew out, and if the airtightness was incomplete due to poor packing, etc. There was a risk of material leakage.

る。 As shown in Figure 1, two pieces of tempered glass are fitted on the outside and inside to provide pressure resistance and airtightness independently, so that even if the outside tempered glass is damaged by an external impact, the inner tempered glass Even if the inner tempered glass breaks or leaks due to internal pressure, the outer tempered glass can prevent the internal substances from ejecting.

得られるのである。 A pressure supply hole 7, a groove 8 carved on the outer periphery of the threaded part of the inner presser metal fitting, and a hole 9 for tightening the inner presser metal fitting are provided in order to perform a pressure tightness test between the outer tempered glass 2 and the inner tempered glass 4. A hole is provided to communicate between the outside and the inside, and a blind plug is loaded into the pressure supply hole 7 during normal use, and the blind plug is removed during a pressure-tightness test, and this hole allows the test to be performed by pressurizing or depressurizing. . As shown in FIG. 2, the assembly method is to insert the inner packing 6 into the viewing window main body 5, fit the inner tempered glass 4, and screw the inner presser fitting 3 to fix the inner tempered glass 4. A groove is carved on the outer periphery of the threaded part of the inner presser metal fitting 3, and a hole communicating with the hole 9 for tightening the inner presser metal fitting is provided. By doing this, after assembling the viewing window, the pressure supply hole 7
The space between the outer tempered glass 2 and the inner tempered glass 4 can be pressurized or depressurized. Next, the outer packing 10 is inserted, the outer tempered glass 2 is fitted, and the outer presser fitting 1 is screwed in to fix the outer tempered glass 2. The assembly is now complete, and a viewing window with double tempered glass that is pressure-resistant and airtight in both the inner tempered glass 4 part and the outer tempered glass 2 part is obtained.
