Problems solved by technology

[0003] However, during flame cleaning, if the oxygen concentration is too small, the workpiece will be over-burned; if the oxygen concentration is too high, it will take a long time for the gas to reach the ignition point, which will affect the flame cleaning efficiency and increase the oxygen consumption.
When the oxygen supply is insufficient, the combustion gas will be insufficient, and the gas will be directly discharged into the air, and the unreacted gas and oxygen cannot be recycled, which not only affects the safety of the operator, but also greatly increases the cost of the enterprise
During the flame cleaning process, as the outlet pressure decreases, the flame will enter the valve body along the gas flow path, ignite the gas in the valve, cause deflagration, and affect the operating safety

The cavitation nozzle and the combustion nozzle are arranged on one side of the valve body, the combustion nozzle is communicated with the upper-layer flow guide channel, the cavitation nozzle is communicated with the lower-layer flow guide channel, gas microcirculation of corners of workpieces is carried out through the circulating device, and the surface treatment quality of the workpieces is improved.

Description

technical field [0001] The invention relates to the technical field of regulating valves for flame cleaners, in particular to a regulating valve for corner cleaning with the function of adjusting local microcirculation. Background technique [0002] In recent years, with the continuous advancement of machining technology, the quality of products has also been continuously improved. Among them, when performing flame cleaning on the surface of continuous castings, it is necessary to adjust the oxygen supply concentration to remove debris on the surface of the workpiece and improve the quality of flame cleaning. [0003] However, during flame cleaning, if the oxygen concentration is too small, the workpiece will be over-burned, and if the oxygen concentration is too high, it will take a long time for the gas to reach the ignition point, which will affect the flame cleaning efficiency and increase the oxygen consumption. When the oxygen supply is insufficient, the combustion ga...
