Description

Stainless steel, cast iron oxy-acetylene cutter
Technical field
The present invention relates to oxy-acetylene cutter, be specially stainless steel, cast iron oxy-acetylene cutter.
Background technology
With oxy-acetylene cutter steel construction cutting being one in service work substantially the most also is the most frequently used maintenance means.But traditional oxy-acetylene cutter can only cut common carbon steel, if it is just powerless to run into materials such as stainless steel or cast iron.The method that generally adopts now for materials such as stainless steel or cast irons is to cut with equipment such as CUTs, but has so not only increased equipment cost, also is inconvenient to use in maintenance process.More existing improved oxy-acetylene cutters can cutting stainless steel, cast iron.Its principle is for being blown into quartz sand, iron powder in the oxycetylene scarfing, emit a large amount of heat energy and form high temperature fluid by fierce oxidizing fire and wash away scarfing, to reach cutting effect, this improved oxy-acetylene cutter structure can be divided into two classes substantially, one class formation is that common oxy-acetylene cutter adds powder feeding mechanism, utilize high pressure oxygen to carry quartz sand during use, iron powder is blown into scarfing from the burning torch outside, its complex structure; Another kind of structure is to seal in a powder jar in the purity oxygen injection pipe of common oxy-acetylene cutter, utilize high pressure oxygen directly with quartz sand during use, iron powder is blown into scarfing from burning torch inside, its shortcoming is that the pressure that works long hours in the powder jar can reduce even produce negative pressure, make the powder discharging not smooth, service efficiency is lower, and the improved stainless steel of this two class, cast iron oxy-acetylene cutter can only carry out the cutting of horizontal plane, once carry out the cutting of non-horizontal surface, powder in the powder jar is setovered under the gravity effect (promptly departing from discharging opening), powder can't spray, and is difficult to satisfy the service work requirement.
Summary of the invention
The present invention for solve existing stainless steel, the discharging of cast iron oxy-acetylene cutter powder is not smooth, the lower and problem that can only carry out horizontal resection of service efficiency provides a kind of stainless steel, cast iron oxy-acetylene cutter.This stainless steel, cast iron oxy-acetylene cutter have high cutting efficiency, and the scope of application strengthens simultaneously, can carry out comprehensive cutting.
The present invention adopts following technical scheme to realize: stainless steel, cast iron oxy-acetylene cutter, comprise the purity oxygen playpipe, on the purity oxygen playpipe, be equipped with and blow the powder device, blow the powder device and comprise body, body is provided with a shunt valve, be fixedly connected with the powder jar on the shunt valve, be provided with injecting tube (a kind of outlet is pyramidal pipe) in the body, have the hole on the injecting tube, be provided with oxygen blowing channel in the shunt valve on the body, hole and oxygen blowing channel shunt valve in of injecting tube inner chamber on injecting tube communicates with the powder jar.During work, hyperbaric oxygen in the purity oxygen playpipe enters injecting tube, be divided into two strands then, one enters to penetrate inhales section (being the pyramidal outlet section of injecting tube), will with penetrate the powder sucking-off of inhaling in the powder jar that section is connected, be injected into scarfing with the cutting torch of oxygen by purity oxygen playpipe, burning torch, vigorous oxidation take place emit a large amount of heat energy and form wash fluid and wash away the scarfing of high temperature and cut off the metal that will cut; Hole, oxygen blowing channel on another stock-traders' know-how injecting tube enter the powder jar, make to keep malleation in the powder jar, keep the powder discharging smooth and easy.
High-pressure spray (gas) is from the injecting tube ejection, and meeting form relative negative pressure around penetrating of injecting tube inhaled section outside, comes penetrating the powder suction on every side of suction section, and this is the known suction principle of penetrating.Penetrating under the guidance of inhaling principle, injecting tube in body the installation site and the form fit of tube cavity be as well known to those skilled in the art or easy realization, promptly penetrating of injecting tube inhaled Duan Yingyu powder jar and communicated, so that the sucking-off powder; The suction section of penetrating of injecting tube goes out to form relative narrow channel space or slit between the wall with body, inhales section negative pressure on every side so that strengthen to penetrate.
During concrete enforcement, described oxygen blowing channel can be with injecting tube on the hole oxygen lance that is tightly connected or is communicated with, perhaps the side at dividing plate forms oxygen blowing channel by dividing plate is set in shunt valve, is tightly connected between dividing plate and the injecting tube.
End in oxygen blowing channel connects metal bellows capable of being bent and deformed, when the cutting operation on horizontal plane, vertical plane, plane, top, metal bellows capable of being bent and deformed is manual in advance crooked, make it to export and be inserted into the position that powder is assembled owing to the gravity effect, powder is blown afloat, thereby guarantee no matter be the horizontal plane cutting operation, still vertical plane or top plane cutting operation, powder is sucked out, realize the smooth and easy discharging under the various applying working conditions, thereby the expansion scope of application can be carried out comprehensive cutting.
Stainless steel of the present invention, cast iron oxy-acetylene cutter are compared with traditional stainless steel, cast iron oxy-acetylene cutter, the ability of its hyperbaric oxygen mixing or sucking-off iron powder, quartz sand increases, the powder discharging is smooth and easy, increased the cutting efficiency of burning torch, the scope of application of this burning torch strengthens simultaneously, the oxy-acetylene cutter that tradition is used for cutting stainless steel, cast iron can only carry out the horizontal plane cutting operation, and this burning torch can carry out comprehensive cutting operation and safe and reliable.
