Изобретение относитс  к вентил торостроению , а конкретно к кожухам вентил торов.This invention relates to a valve manufacturer, and more specifically to fan housings.

Известен кожух вентил тора, на внутренней поверхности которого нанесен звукопоглощающий материал fij.A fan casing is known, on whose inner surface a sound-absorbing material fij is applied.

Недостатком такой конструкции  вл етс  НИЗКИЙ уровень шумоглушени .The disadvantage of this design is the LOW level of sound attenuation.

Наиболее близким по технической сущности и достигаемому эффекту к изобретению  вл етс  кожух вентил тора с кольцевым коробчатым сечением, внутренн   бокова  стенка которого выполнена перфорированной 2.The closest to the technical essence and the achieved effect to the invention is a fan casing with an annular box-section, the inner side wall of which is perforated 2.

Недостатком такой конструкции  вл етс  низка  эффективность шумоглушени  при ограниченных габаритах кожуха.The disadvantage of this design is the low efficiency of sound attenuation with limited dimensions of the casing.

Цель изобретени  - пов{дшение эффективности шумоглушени .The purpose of the invention is to increase the effectiveness of sound attenuation.

Указанна  цель достигаетс  тем, что одна из торцевых стенок корпуса также выполнена перфорированной.This goal is achieved by the fact that one of the end walls of the housing is also perforated.

На фиг.1 изображен кожух, продольный разрез; на фиг.2 - сечение А-А На фиг.1.Figure 1 shows the casing, a longitudinal section; figure 2 - section aa in figure 1.

Кожух 1 вентил тора с кольцевым коробчатым сечением имеет перфорированные внутреннюю боковую стенкуThe casing 1 of the fan with an annular box-section has a perforated inner side wall

2 и одну из торцевых стенок 3, радиальными перегородками 4 внутренн   полость 5 кожуха 1 разделена на камеры 6.2 and one of the end walls 3, by radial partitions 4, the internal cavity 5 of the casing 1 is divided into chambers 6.

При работе вентил тора происходит эффективное глушение шума при последовательном проникновении звуковой волны через перфорированные боковую и торцевую стенки.When the fan is operating, effective noise damping occurs with the successive penetration of the sound wave through the perforated side and end walls.
