flammable gaswith automatic ignition control

Abstract

The invention provides an automatic ignition control device for inflammable gas. The automatic ignition control device comprises a pneumatic valve, an ignition needle, a controller, a master switch and an ignition switch. The controller comprises a gas source control unit and an ignition control unit, wherein the gas source control unit is electrically connected with the master switch and the pneumatic valve. The master switch controls the pneumatic valve to work through the gas source control unit, the ignition control unit comprises a pulse signal emitter, the pulse signal emitter is electrically connected with the ignition switch and the ignition needle and emits pulse signals to the ignition needle under control of the ignition switch, and the ignition needle is controlled through the pulse signals. Adopting the structure, the automatic ignition control device for the inflammable gas has the advantages that safety accidents caused by ignition errors can be prevented effectively, working efficiency is improved greatly, labor intensity is reduced and cost is saved.

Description

Technical field [0001] The invention relates to the field of welding equipment control, in particular to a flammable gas belt automatic ignition control device. Background technique [0002] Welding equipment is an important equipment in industrial production, and the control of welding equipment is an important link in the welding process, which is directly related to welding safety and production efficiency [0003] At present, in the prior art, the gas control valve is manually opened. It will often happen that the gas (such as nitrogen, oxygen, acetylene, etc.) is still circulating when not welding, and the gas cannot be effectively controlled, and in many cases there is waste. . In addition, gas guns (such as gas cutting torches, flame brazing torches, etc.) are all used for manual ignition, and ordinary artificial lighters have low ignition efficiency, such as: flame brazing positions: hundreds of times a day, which seriously affects production Benefit; and it is easy to in...

AI Technical Summary

Problems solved by technology

[0003] At present, in the prior art, the gas control valve is manually opened, and the gas (such as nitrogen, oxygen, acetylene, etc.) is still circulating when the welding is not performed, and the gas cannot be effectively controlled, and there is a waste of time in many cases.

And the guns that use gas (such as gas cutting guns, flame brazing guns, etc.) all use manual ignition, and manual ordinary lighters are ineffective in lighting, such as: flame brazing jobs: hundreds of times a day, which seriously affects production benefit; and it is easy to injure the operator when igniting, which may lead to safety accidents in serious cases
