The oxy-acetylene mixed gas of burning is extinguished immediately.
A kind of device for preventing burning gases to be tempered provided by the utility model, uses according to the following steps:
S1, oxy-acetylene gas combustion apparatus is installed, combustion apparatus includes sequentially connected Ignitable gas devices 210, mistake
Connector 212 and shut-off valve 211 are crossed, Ignitable gas devices 210 is connected with shut-off valve 211 by pipeline, and shut-off valve 211 passes through pipeline
It is connected with transit joint 212, acetylene pipeline 213 is arranged in transit joint 212, and check valve 214 is provided on acetylene pipeline 213
With the device 215 for preventing burning gases to be tempered, check valve 214 can be such that the gas unidirectional in acetylene pipeline 213 flows.
Shut-off valve 211 is conventional manual valve in this step, or is solenoid valve, and solenoid valve can be controlled by circuit
System.In the present embodiment, Ignitable gas devices 210, transit joint 212, shut-off valve 211, acetylene pipeline 213, check valve 14 are equal
For existing mature technology equipment.The gas filled in Ignitable gas devices 210 is inert gas, inert gas such as: argon gas, it is lazy
Property gas cannot be burned.
Transit joint 212 is located at the middle part of acetylene pipeline 213, and transit joint 212 is located at oxy-acetylene mixing arrangement and acetylene
Between gas source, acetylene gas source is that acetylene pipeline 213 provides acetylene gas.Can shut-off valve 211 can control inert gas enter
Inside acetylene pipeline 213.
S2, it is passed through that acetylene gas is mixed, and acetylene gas is connect inside acetylene pipeline 213 by transition in acetylene pipeline 213
Enter oxy-acetylene mixing arrangement, burning operation relevant to carrying out after oxygen mix after first 212.
After S3, in step s 2 mixed gas are burnt, Guan Huoshi is needed, opens shut-off valve 211, Ignitable gas devices 210
In compressed air by shut-off valve 211 enter transit joint 212 and then enter acetylene pipeline 213 in, compressed air and step
The acetylene gas of rapid S2 is mixed and fed into mixing arrangement, and mixed gas stops burning.
After compressed air passes through shut-off valve 211, it is introduced into transit joint 212, is then entered again by transit joint 212
In acetylene pipeline 213.After compressed air and acetylene gas, oxygen mix, the gas originally to burn in work extinguishes, and no longer fires
It burns.
In the mixed gas flame combustion process of oxygen and acetylene gas, Guan Huoshi is needed, shut-off valve 211 is opened, makes to compress
Inert gas in gas device 210 makes flame stop firing immediately because of acetylene deficiency if argon gas enters in acetylene pipeline 213
It burns, without generating carbon distribution or acetylene deficiency since acetylene combustion is insufficient, flame is counter to be burnt into heater because directly closing gas
It is interior.Simultaneously because being provided with check valve 214 in acetylene pipeline 213, check valve 214 is prevented due to hypertonia, compressed gas dress
It sets the gas in 210 and enters acetylene cylinder direction.Due to there is continuous compressed air to enter in acetylene pipeline 213, acetylene pipeline 213
It is interior to continue there are the outflow of the air-flow of pressure, without generating detonation because of intracavitary external differential and being tempered because of heating gun or heater,
Therefore whole process solves the generation of carbon distribution and detonation tempering phenomenon when closing fire.
Those of ordinary skill in the art will understand that the embodiments described herein, which is to help reader, understands this reality
With novel principle, it should be understood that the scope of the present invention is not limited to such specific embodiments and embodiments.
Those skilled in the art can be made according to the technical disclosures disclosed by the utility model it is various do not depart from it is practical
Novel substantive various other specific variations and combinations, these variations and combinations are still within the protection scope of the present invention.
