Safety joint with reverse flow and backfire prevention feature for small ponds.
This is a compact safety fitting equipped with a super-miniature backflow and backfire prevention function on the global socket side, designed for gas cutting machines or portable automatic machines. It can prevent backflow and backfire energy occurring in the blowpipe at the source while the energy is still small, effectively stopping both backflow and backfire generated by fuel gas and oxygen, and its structure for reliably preventing backfire has also been patented.

basic information
■ Backflow Prevention Mechanism Backflow of gas occurs due to operational errors with the blowpipe. It is particularly prone to returning on the fuel gas side, and this phenomenon is prevented by the backflow valve. ■ Backfire Prevention Mechanism Backfires that occur inside the blowpipe are extinguished by the flame extinguishing filter, and the backfire pressure activates the backflow valve to stop the gas supply. Once the backfire subsides and normal operation resumes, it can continue to be used as is. However, if backfires occur repeatedly, the extinguishing filter may become clogged with soot, leading to poor gas flow. When this phenomenon is observed, it is necessary to replace the mini tackle. ■ Color-Coded Sockets for Different Gases The socket for oxygen is marked with a "blue" label, while the socket for fuel gas is marked with a "red" label, ensuring that there are no mistakes in handling. Additionally, the dimensions of the plugs for oxygen and fuel gas are different to prevent any mix-ups. ■ Recommendation for Combined Use with Oxygen Backfire phenomena can occur not only on the fuel gas side but also on the oxygen side. To ensure safety, it is necessary to use it in conjunction with oxygen.
Applications/Examples of results
■Global Mini Tackle Usage Conditions To maintain performance with the Apollo Mini Tackle, the conditions are that for cutting blowpipes, a medium-sized cutter must be used, and for type A automatic cutters, it must be up to type 100 nozzle number 4. ■Global Mini Tackle Maintenance Inspection Please be sure to inspect the extent of backfire phenomena, check if the blowpipe is damaged, and identify the cause of backfire to confirm whether it can be used normally before reusing it. If the gas flow becomes poor, it is due to clogging of the flame extinguishing filter, so please replace it and request repairs from the manufacturer.
Company information
Since its founding in 1918 (Taisho 7), Koike has served as an opinion leader in machine tools utilizing "gas energy," contributing to the development of key industries. During this time, in line with the progress of the era, we have developed cutting machines utilizing "plasma" and "laser" ahead of others, and have commercialized advanced automated systems using NC technology. At the same time, we have established a comprehensive total system to meet all customer needs, ranging from "gas, welding, and cutting to related equipment."
