Description
Изобретение относитс к вентил то ростроению.This invention relates to a sponclery valve.
Целью изобретени вл етс повышение прочности.The aim of the invention is to increase the strength.
На фиг. 1 показана пластмассова лопатка, общий вид;, на фиг. 2 - то же, сечени у корн и на периферии.FIG. 1 shows a plastic paddle, general view ;, FIG. 2 - the same, sections at the root and on the periphery.
Пластмассова лопатка рабочего колеса осевого вентил тора содержит перо 1 и расположенный в теле пера 1 продольный стержень 2 с поперечными пластинами 3, причем стержень 2 имеет переменное сечение, уменьшающеес The plastic blade of the impeller of the axial fan contains a feather 1 and a longitudinal rod 2 located in the body of the feather 1 with transverse plates 3, the rod 2 having a variable cross-section decreasing
от корн к периферии пера 1, а пластины 3-изогнуты по средней линии его профил и расположены к оеи стержн 2 под острым углом о4 с вершиной, направленной к периферии пера 1.from the root to the periphery of the pen 1, and the plates are 3-curved along the midline of its profile and are located towards the rod 2 at an acute angle o4 with the apex directed to the periphery of the pen 1.
Повьшгение прочности лопатки достигаетс повышением величины поперечного сечени стержн 2 пропорционально повьш1ению окружной скорости с ростом радиуса колеса и поддержанием центробежной силы на посто нном уровне во всех цилиндрических сечени х лопатки.Strength of the blade is achieved by increasing the cross section of the rod 2 in proportion to the increase in peripheral speed with increasing wheel radius and maintaining centrifugal force at a constant level in all cylindrical sections of the blade.
