Beschreibung
Zusammenfassung:The utility model discloses a double-pole ignition needle device, which comprises a central electrode and a side electrode, the central electrode is arranged at the end part of an insulating porcelain sleeve, a shell is sleeved outside the insulating porcelain sleeve, the side electrode is arranged at the inner side of the shell through an inner protective layer, and the end part of the side electrode is bent towards the side surface to form a bent part. The double-pole ignition needle is scientific and reasonable in structural design, the double-pole ignition needle is arranged so that the center electrode can not move, the high-temperature-resistant metal sleeve shell is specially welded to the ignition needle shell to restrain and position the electrodes, the ignition success rate is high, the end of the side electrode is bent to form the bent part, the end of the side electrode is close to the end of the center electrode, and therefore the ignition efficiency is improved. The fuel gas can be fully ignited
