Abstract
Изобретение относитс к технике вентил ции и вл етс усовершенствованием основного изобретени по авт. св. № 1520255. Целью изобретени вл етс упрощение и повышение качества монтажа внутреннего каркаса воздуховода . Виброизолирующа секци воздуховода содержит наружный и внутренний каркасы 1 и 2, последний из которых выполнен из гибкого материала и установлен на основном и допоп- нительном пластмассовых фланцах 3 и 4. Дополнительный фланец 4 выполнен из эластичного материала, например поливинилхлорида, и имеет вырезы 5 треугольной формы со стороны основного фланца 3,равномерно расположенные по контуру фланца 4. Дроссельные отверсти 6 размещены между вырезами 5 дополнительного фланца 4. Между наружным и внутренним каркасами 1 и 2 образована проточна полость, имеюща выполненные в основном фланце 3 входные отверсти (не показано). 2 ил. (ЛThe invention relates to a technique of ventilation and is an improvement of the basic invention according to the author. St. No. 1520255. The purpose of the invention is to simplify and improve the quality of installation of the inner frame of the duct. The anti-vibration section of the duct contains outer and inner frames 1 and 2, the latter of which is made of flexible material and installed on the main and additional plastic flanges 3 and 4. Additional flange 4 is made of elastic material, for example polyvinyl chloride, and has cutouts 5 of a triangular shape from the side of the main flange 3, evenly spaced along the contour of the flange 4. The throttle holes 6 are placed between the notches 5 of the additional flange 4. Between the outer and inner frames 1 and 2 there is formed a proto ANT cavity having a flange formed mainly three inlets (not shown). 2 Il. (L
