How to Adjust Lighter Valve

First, exhaust the air in the lighter, and press the air inlet at the bottom of the lighter with a screwdriver. The valve for exhausting air to adjust the flame size cannot be closed.

Lighters are small ignition devices. It is mainly used for lighting fire, smoking, cooking and so on. The main components of lighter are ignition mechanism and gas storage box. When the ignition mechanism moves, the generator ignites the gas area to ignite the gas. Ignition mechanism is the most active part in the evolution of lighters, and it is also the part with complex structure.

According to the characteristics of ignition mechanism, lighters can be divided into flint steel wheel lighters, piezoelectric ceramic lighters, magnetic induction lighters, battery lighters, solar lighters and microcomputer lighters. The gas used in lighters is mainly combustible gas.

The fuel used in lighters is mainly combustible gas. Gasoline was widely used in the early days, but it is rarely used now because of its peculiar smell. Butane, propane and liquefied petroleum gas are widely used. They are pressurized and filled into a closed air box. Once released into the air, they absorb heat, vaporize and expand rapidly, and are easily ignited.

Butane (CH3-CH2-CH2-CH3) used in lighters is n-butane, which is the general name of two alkanes and hydrocarbons with the same molecular formula (C4H 10). Include n-butane and isobutane (2- methylpropane). Butane is a flammable, colorless and liquefied gas. It is an important raw material for the development of petrochemical industry and organic raw materials, and its use has been paid more and more attention.
