Summary:The utility model discloses ventilation equipment for an assembly type building wall in constructional engineering, which relates to the field of constructional engineering and comprises a first mounting cylinder and a second mounting cylinder, and extending plates are fixedly connected to the edges of the ends, far away from each other, of the first mounting cylinder and the second mounting cylinder. And sealing rings are adhered to the sides, close to each other, of the two extension plates. The noise reduction layers and the filter screens are arranged on the first mounting cylinder and the second mounting cylinder, the sound insulation plates on the noise reduction layers play a role in sound insulation, the ventilation holes in the sound insulation plates play a role in sound absorption and noise reduction through the sound absorption cotton plates, the good noise reduction effect is achieved, the filter plates play a role in filtering dust in air, and the noise reduction effect is good. Elastic sealing
