Abstract

1. Электродуговой плазмотрон, содержащий диэлектрический корпус, в котором установлены полый медный электрод, сопло и водоохлаждаемый соленоид, связанный с токопроводом и электродом через клемму-вставку, каналы подвода воды и газа, при этом электрод и сопло закреплены в диэлектрическом корпусе с помощью цилиндрического кожуха с коническим сужением и осевым отверстием в нижней его части, а в торце медного электрода установлен торцевой завихритель, выполненный в виде втулки, отличающийся тем, что между полым медным электродом и соплом установлен кольцевой изолятор, к которому герметично примыкают основной завихритель, выполненный в виде кольца с тангенциальными отверстиями, и кольцевой водяной коллектор, причем основной и торцевой завихрители связаны через золотники перераспределения расхода газа с каналом подачи газа, а соленоид расположен внутри стальной цилиндрической гильзы, один торец которой примыкает к клемме-вставке, установленной в зоне стыка полого медного электрода и кольцевого водяного коллектора, при этом клемма-вставка выполнена со сквозными отверстиями, соединяющими кольцевой водяной коллектор с полостью, образованной стенками электрода и цилиндрической гильзы, а другой торец гильзы примыкает к диэлектрическому корпусу, при этом соленоид выполнен из нескольких параллельных витков медного изолированного провода одинакового сечения, выходные концы соленоида, каждый в отдельности, припаяны равномерно по окружности к клемме-вставке, а в торцевом завихрителе выполнены сквозные тангенциальные отверстия, соединяющие канал подачи газа с полостью электрода.2. Электродуговой плазмотрон по1. An arc plasma torch containing a dielectric housing in which a hollow copper electrode, a nozzle, and a water-cooled solenoid are connected to the current lead and the electrode through an insert terminal, water and gas supply channels, while the electrode and nozzle are fixed in a dielectric housing using a cylindrical casing with a conical narrowing and an axial hole in its lower part, and in the end of the copper electrode there is an end swirler made in the form of a sleeve, characterized in that between the hollow copper electrode and the nozzle An annular insulator has been updated, to which the main swirl made in the form of a ring with tangential openings is tightly adjacent, and an annular water collector, the main and end swirls being connected through gas flow redistribution spools to the gas supply channel, and the solenoid is located inside a steel cylindrical sleeve, one end which is adjacent to the insert terminal installed in the joint zone of the hollow copper electrode and the annular water collector, while the insert terminal is made with through holes and connecting the annular water collector with the cavity formed by the walls of the electrode and the cylindrical sleeve, and the other end of the sleeve adjoins the dielectric body, the solenoid is made of several parallel turns of a copper insulated wire of the same cross section, the output ends of the solenoid, each individually, are soldered uniformly along the circumference to the insert terminal, and through the end swirler, through tangential openings are made connecting the gas supply channel with the electrode cavity. 2. Arc plasma torch
