The structure and principle of torch

1. Definition
A pipelineless handheld tool that controls the combustion of gas to form a cylindrical flame for heating and welding, also known as a handheld torch (usually butane is used for gas)
2. Structure
The 220g Butane Gas Burner KLL-9005D palm torch is divided into two main structures: a gas storage chamber and a surge chamber. The mid-to-high-end products also have an ignition structure.
Gas storage chamber: also known as a gas box, which contains gas, and its composition is generally butane, which transports gas to the surge chamber structure of the tool.
Surge chamber: This structure is the main structure of the palm torch. The gas is sprayed out of the muzzle through a series of steps, such as receiving gas from the gas storage chamber, and then filtering and regulating the flow.
Three, working principle
Adjust the pressure and variable flow of the gas to spray out the muzzle and ignite it to form a high-temperature cylindrical flame for heating and welding.
Four, specifications
In terms of structure, there are two types of palm torches, one is the air box integrated palm torch, and the other is the air box separated fire torch head.
1) Air box integrated palm torch: easy to carry, generally smaller in size and lighter than the separate type.
2) Handheld flame gun head with separate gas box: It needs to be connected to a cassette gas cylinder, which is larger in weight and volume, but has a large gas storage capacity and a longer continuous use time.
Five, characteristics
Compared with welding torches and other tools that require pipeline transportation of gas, portable torches have the advantages of an integrated gas box and wireless portability. The flame temperature of the gun generally does not exceed 1400 degrees.
The windproof lighter can be said to be the predecessor of the portable flamethrower. The mid-to-high-end portable flamethrower has been innovatively expanded in the following points to increase its use value, expand its use, and be competent for more demanding working environments.
1. Air filter structure: reduce the probability of clogging, ensure the performance of the tool, and increase the lifespan.
2. Pressure regulating structure: optimized control of gas flow, with higher flame size and temperature.
3. Thermal insulation structure: reduce the heat conduction effect and ensure the stability of the pressure regulating structure and gas flow.
