What is the reason for the hissing sound of a leaking lighter?
2 Answers
A lighter leaking gas with a hissing sound poses risks of explosion and combustion, so it should be placed in a safe location first. Below are the precautions for using lighters: 1. Do not attempt self-repair: The structure of gas lighters is very complex, especially the numerous springs and hairsprings inside. Due to space and hardness issues, they cannot be reassembled without specialized tools once disassembled. 2. Adjust the flame according to the manual: After obtaining the device, do not frequently adjust the flame. Once the flame is set, avoid further adjustments. When adjusting, pay close attention to the key points in the manual, and do not exceed 10 degrees at a time. It is particularly important to note that some adjustment mechanisms will render the device unusable if turned beyond 90 degrees. 3. Use clean gas for refilling: It is recommended to use specialized gas canisters. Although counterfeit products may still exist, major cities generally offer reliable options. If using ordinary gas canisters, ensure they are clean. A simple method is to press the nozzle and smell it before refilling; if odorless, the gas is suitable. 4. Avoid direct sunlight exposure: Direct sunlight on a gas lighter does not cause explosion but leads to the accumulation of a large amount of mixed gas in the tube. Upon ignition, the gas may break through the seal, causing permanent leakage due to seal failure.
I've encountered situations where my lighter made a hissing sound while I was smoking, which is usually caused by a faulty valve seal. After prolonged use, internal components like rubber rings wear out or the valve spring loosens, allowing gas to slowly leak out. Temperature changes can worsen the issue—high temperatures in a car during summer cause expansion and make leaks more likely. This isn't safe; if there's a spark or it's near an open flame, it could lead to a fire or explosion. I recommend replacing the lighter immediately instead of continuing to use it, and avoid buying cheap, low-quality products. When storing lighters, keep them away from high-temperature environments, and don't overfill them with gas—leave some space to prevent expansion. Regularly check the condition of your lighter, and if you notice any unusual sounds, address it right away—safety comes first.
