Description
Известно чувствительное сопло дл измерени рассто ни до поверхности приближаемого предмета, содержащее подвод щий и отвод щий каналы. Дл повышени чувствительности сопла его часть, обращенна к приближаемому предмету, выполнена сужающейс , а подвод щий и отвод щий каналы выполнены во втулке, устанавливаемой внутри сопла и закрепл емой, например, при помощи кле .A sensing nozzle for measuring the distance to the surface of an approaching object, containing feed and discharge channels is known. To increase the sensitivity of the nozzle, its part facing the object being approached is made tapering, and the inlet and outlet channels are made in a sleeve installed inside the nozzle and fixed, for example, by means of glue.
Конструкци сопла показана на чертеже.The design of the nozzle is shown in the drawing.
В расточке I корпуса 2 установлена втулка 3 Полость сопла, обращенна к приближаемому предмету , выполнена в виде конуса 4 и цилиндрического отверсти 5, Во втулке 3 выполнены подвод щий канал 6 с дросселем 7 и отвод щий анал 8.The bore 3 is installed in the bore I of the housing 2, the nozzle cavity facing the object being approached is made in the form of a cone 4 and a cylindrical bore 5.
Площадь проходного сечени дроссел 7, отверсти 5 и конуса 4 относ тс друг к другу как The flow area of the throttles 7, holes 5 and cone 4 are related to each other as
1:36:400. Угол конусности выбираетс равным 60 . Отношение диаметра конуса 4 к рассто нию между ос ми каналов 6 и 8 составл ет 6:5, причем упом нутые оси симметричны относительно оси сопла в целом и лежат с ней в одной плоскости.1: 36: 400. The angle of taper is chosen to be 60. The ratio of the diameter of the cone 4 to the distance between the axes of the channels 6 and 8 is 6: 5, and the said axes are symmetrical about the axis of the nozzle as a whole and lie with it in the same plane.
Благодар попаданию потока, вытекающего из дроссел 7, на поверхность конуса 4 создаетс закрутка потока внутри сопла и вакуум в канале 8 при свободном истечении потока через отверстие 5,Due to the flow coming out of the throttles 7, a swirl of the flow inside the nozzle and a vacuum in the channel 8 are created on the surface of the cone 4 and the flow through the hole 5 is free;
При приближении к соплу какого-либо предмета давление на оси сопла достаточно быстро нарастает и передаетс в канал 8.When approaching the nozzle of any object, the pressure on the axis of the nozzle increases quite quickly and is transmitted to the channel 8.
