CNC flame cutter's flame return
I believe that for flame cutting in the industry we are no stranger, whether it is manual flame cutting, or semi-automatic cutting machine, imitation cutting machine, and even today's CNC flame cutting machine, these are the use of flame cutting, no matter how advanced, how high technical requirements of the machine tool, when it comes to flame cutting, we have to consider the flame cutting process of the backfire problem.
Refring is a common problem encountered in CNC cutting machine flame cutting, the use of gas, liquefied gas or propane these milder gases as gas, the phenomenon of refring is less, for acetylene, a more difficult to control the gas, in the cutting process of the phenomenon of refring will appear ordinary.
For the use of manual cutting or semi-automatic cutting machine, imitation cutting machine users, in the face of tempering phenomenon, more trouble to deal with, when encountering serious tempering may burn the cut gun, cut mouth, tracheas, etc. , more serious may cause personal injury to cutting workers, so the phenomenon of flame cutting back to fire has to attract people's attention. At this stage, CNC flame cutting machine is very important for return fire, CNC flame cutting machine once the phenomenon of fire back in the cutting process may cause more serious consequences, so our CNC flame cutting machine is equipped with a device to prevent return fire.
The return valve is the necessary device on the CNC flame cutting machine cutting gun, the CNC flame cutting machine cutting gun is longer, after installing the fire return valve, after encountering the CNC flame cutting machine fire back, do not worry, the flame will hurt the CNC flame cutting machine on the upper tracheas and solenoid valve, even the cut mouth will not be damaged. In order to speed up the cutting efficiency, the user using CNC flame cutting machine removed the return valve above the CNC flame cutter, which is not desirable.
