A cordless handheld tool that controls the combustion of gas to form a columnar flame for heating and welding, also known as a handheld torch (gas generally uses butane)
1. Structure
The OEM Butane Fire Gun China Manufacture KLL-8816D into two main structures, the gas storage chamber and the pressure regulating chamber, and the medium and high-end products also have an ignition structure.
Gas storage chamber: also known as gas box, there is gas in it, the composition is generally butane, and it is used to transport gas to the surge chamber structure of the tool.
Pressure regulating chamber: This structure is the main structure of the hand-held flamethrower. It receives gas from the gas storage chamber, and then passes through a series of steps such as filtering, regulating and changing the flow, and then spraying the gas out of the gun.
2. Working principle
The gas is pressure-regulated and variable-flow sprayed out of the muzzle and ignited to form a high-temperature cylindrical flame for heating and welding.
3. Compared with tools such as welding torches that require pipeline transportation of gas, the portable torch has the advantages of integrated gas box and wireless portability, but it is limited to the factors that the portable torch relies on oxygen combustion in the air and gas pressure. The flame temperature of the flamethrower 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, which has improved its use value, expanded its use, and is competent in more demanding working environments.
1. Air filter structure: reduce the probability of blockage, ensure the performance of the tool, and improve the service life.
2. Pressure regulating structure: optimized control of gas flow, with higher flame size and temperature.
3. Insulation structure: reduce the heat conduction effect and ensure the stability of the pressure regulating structure and gas flow.
