The utility model discloses a guide ventilation
cut-off
waveguide window for a dangling type explosion-proof wave shielding valve, which belongs to the technical direction of
waveguide windows and comprises an inclined ventilation
cut-off
waveguide window, a static pressure absorption cabin, a horizontal ventilation
cut-off waveguide window, a door leaf outer door plate and a door leaf inner door plate. The oblique ventilation cut-off waveguide window is welded to one end of the outer door plate of the door leaf, the oblique ventilation cut-off waveguide window, the static pressure absorption cabin and the horizontal ventilation cut-off waveguide window are used in cooperation, a double-layer combined ventilation waveguide structure is adopted, and a
wave absorption material is attached to the static pressure absorption cabin, so that electromagnetic
waves are reflected and absorbed for multiple times in the static pressure absorption cabin; electromagnetic wave energy entering the shielding body is greatly weakened, the overall shielding effectiveness is improved, meanwhile, the static pressure absorption cabin can evenly distribute
air volume, stabilize
airflow, reduce
airflow vibration and
noise, convert part of
dynamic pressure into static pressure, reduce
dynamic pressure loss, improve the efficiency of a ventilation
system, enable air to be blown farther, and effectively reduce the length of the hexagonal waveguide structure.
