Description

Technical Field

[0001] The utility model relates to the technical field of cutting nozzles, in particular to a plasma cutting nozzle with a cooling jacket. Background Art

[0002] The cutting nozzle is installed on the head of the cutting torch. It can gather the flame and spray high-pressure oxygen, which plays a very important role in gas cutting.

[0003] In the prior art, a plasma cutting nozzle generates high temperature when in use, and the high temperature causes heat damage to the plasma cutting nozzle, so a cooling jacket is used to provide a cooling effect on the plasma cutting nozzle. However, the cooling jacket is fixedly arranged on the plasma cutting nozzle. If one of the two is damaged, both will be scrapped. If the cooling jacket is detachably connected to the plasma cutting nozzle, it can be replaced in a targeted manner to reduce unnecessary waste. For this reason, we propose a plasma cutting nozzle with a cooling jacket. Utility Model Content
