Description
Известны газораспределительные устройства дл огнезачисгных машин, встроенные-в газорежущий блок и снабженные двум камерами с р дом отверстий дл подачи сквозь них кислорода и горючего газа. Однако при помощи таких устройств затруднено плавное регулирование ширины фронта огневой зачистки поверхности металла.Gas distributing devices for fire-charging machines are known, which are integrated into the gas-cutting unit and are equipped with two chambers with a series of openings for supplying oxygen and combustible gas through them. However, using such devices makes it difficult to smoothly adjust the width of the front of the fire stripping of the metal surface.
В описываемом устройстве дл плавного регулировани ширины фронта огневой зачистки поверхности металла применены прот нутые вдоль отверстий в каждой камере гибкие газонепроницаемые ленты и подвижные каретки, прижимающие их к отверсти м. Дл этого кажда каретка снабжена двум роликами, один из которых с помощью пружины производит прижим ленты над частью отверстий, а второй поддерживает ее в приподн том состо нии над другой частью отверстий.In the described device for smooth adjustment of the width of the front of the fire stripping of the metal surface, flexible gas-tight tapes and movable carriages pressed against the holes are applied along the holes in each chamber. Each carriage is equipped with two rollers, one of which with a spring produces a clip over the part of the holes, and the second keeps it in a raised position above the other part of the holes.
На фиг. 1 изображено устройство в поперечном разрезе: на фиг. 2 - разрез по А-А на фиг. 1.FIG. 1 shows a device in cross section: FIG. 2 is a section along A-A in FIG. one.
Газораспределительное устройство дл огнезачистных мащин состоит из коробки /, внутри которой и.меютс камеры 2 и 5, куда по трубопроводам 4 и 5 подаютс кислород и горючий газ, газонепроницаемых лент 6 и 7, проход щих внутри камер 2 и 3, кареток 8, снабженных роликами 9 и 10, винтовых механизмов // передвижени кареток 8 V. механизма 12 нат жени лент 6 и 7.The gas distributing device for fire-fighting machines consists of a box / in which chambers 2 and 5 are placed, where oxygen and combustible gas are supplied through pipelines 4 and 5, gas-tight tapes 6 and 7 passing inside chambers 2 and 3, carriages 8 equipped with rollers 9 and 10, screw mechanisms // movement of the carriages 8 V. mechanism 12 for tensioning the strips 6 and 7.
При необходимости прекращени доступа кислорода и горючего газа к части секций газорежущего блока 13 происходит перемещение кареток 8 вдоль устройства, во врем которого ролики 9 под воздействием пружин 14 прижимают ленты 6 7 к. отверсти .м 15 и 16, а ролики 10 поддерживают эти ленты над остальной частью отверстий /5 м 16, сквозь которые продолжаетс поступление кислорода и горючего газа. Герметичность перекрыти части отверстий 15 и 16 обеспечиваетс за счет разности давлений по обе стороны лент 6 и 7.If it is necessary to stop the access of oxygen and combustible gas to part of the sections of the gas-cutting unit 13, the carriages 8 move along the device, during which the rollers 9 under the influence of the springs 14 press the belts 6 7 towards the openings 15 and 16, and the rollers 10 support these tapes over the rest of the holes / 5 m 16, through which continues the supply of oxygen and combustible gas. The tightness of the overlap of part of the holes 15 and 16 is provided by the pressure difference on both sides of the belts 6 and 7.
Описываемое устройство позвол ет упростить газораспределение и повысить его надежность, сократить расход кислорода и горючего газа, а такжеуменьшит, износ газонепроницаемой ленты.The described device allows to simplify gas distribution and increase its reliability, reduce the consumption of oxygen and combustible gas, as well as reduce the wear of the gas-tight tape.
