Description
чении сопла имеет пр молинейные участки 9 и 10 и криволинейные участки 11 к 12. Участки 9 и 10 образуют острый уго . вершина которого направлена к выходу из сопла. Криволинейные участки Ни. /Ij предстарл ет собою части парабол 13 и 14 (см. фиг. 2), вершины которых смещены одна относительно другой по оси сопла. Сопло имеет центральное отверстие 15 дл прохода нити и может быть закреп- лено на станке при помоши стержн 1в. Пр молинейные участки 9 и 10 полости 7 расположены по касательной к криволинейным участкам 11 и 12.The nozzle has straight sections 9 and 10 and curvilinear sections 11 to 12. Parts 9 and 10 form a sharp corner. the top of which is directed to the exit of the nozzle. Curved sections of Ni. / Ij presents the parts of parabolas 13 and 14 (see Fig. 2), the vertices of which are displaced one relative to the other along the axis of the nozzle. The nozzle has a central hole 15 for the passage of the thread and can be fixed on the machine with the help of the rod 1c. The straight sections 9 and 10 of the cavity 7 are located tangentially to the curved sections 11 and 12.
Рабоча среда, например жидкость, в период работы станка подаетс через отверсти 8 в полость 7 и выходит струей из сопла, захватыва npoxonsauyro через отверстие 15 уточную нить и прокладыва ее в зев основы. Проход ша через полость жидкость имеет характеристику скорости, показанную на фиг. 2 кривой 17. Согласно кривой 17 в части полости, ограниченной участками 11 и 12, ускорение достигает своей наибольшей величины. При введении уточной нити в зев основы жидкости кратковременно сообщаетс высокое давление. То количество жидкости, которое к началу возрастани давлени Working medium, such as liquid, during the operation of the machine is fed through the holes 8 into the cavity 7 and flows out of the nozzle, capturing the npoxonsauyro through the hole 15 of the weft thread and laying it into the orifice of the base. The passage of the sha through the cavity has the fluid velocity characteristic shown in FIG. 2 curve 17. According to curve 17, in the part of the cavity bounded by sections 11 and 12, the acceleration reaches its maximum value. When a weft yarn is introduced into the shed of the base fluid, high pressure is briefly reported. The amount of fluid that, when the pressure starts to increase
уже находитс в полости, в своем движении не npeTepnejBaeT заметного изменени направлени и поэтому получаетс стру с большой скоростью, достаточной дл надежной прокидки уточкой нити.is already in the cavity, in its movement there is not a noticeable change in direction, and therefore a jet is produced at a high speed sufficient to reliably let the weft yarn through.

4, Сопло дл прокидки уточной нити на ткацком станке содер :ашее корпус и сердечник , расположенный внутри корпуса так, что между ними образована полость дл подачи рабочей среды, имеюща в осевом сечении сопла пр молинейные и криволинейные участки, при этом сопло имеет центральное отверстие дл прохода нити, отличающеес тем, что, с целью повышени наде ;ности прокидки нити, криволинейные участки полости представл ют собою части парабол, вершины которых смещены одна относительно другой по оси сопла, а пр молинейные участки образуют острый угол с вершиной направленной к выходу из сопла.4, The nozzle for inserting the weft yarn on a weaving machine contains: the first case and the core located inside the case so that between them there is a cavity for supplying the working medium, having in the axial section of the nozzle straight lines and curvilinear sections, the nozzle having a central opening for the passage of the thread, characterized in that, in order to increase the hope of turning the thread, the curvilinear portions of the cavity are parts of parabolas, the vertices of which are displaced one relative to the other along the axis of the nozzle, and the straight sections form corner with the apex directed to the exit from the nozzle.
2. Сопло поп. 1, отличающее с тем, что пр молинейные участки полости расположены по касательной к криволинейным участкам.2. Nozzle pop. 1, characterized in that the straight portions of the cavity are located tangentially to the curved portions.
