Abstract

A flow regulating method and apparatus for hydrocarbon gas, characterized in that, hydrocarbon combustion gas is discharged from the liquid state air vessel as a first phase, at first the discharged combustion gas is decompressed by the flow limiting member to limit the upper limit flow in the using range to the max flow, in the limiting max flow range, the compressible flow regulating member from outside can regulate to random flow. The deterioration with time of elastic foaming object is suppressed by combining the minuteness porous membrane with the porous elastic foaming object, thereby obtaining the steady flow regulation persisting for a long time.

Description

technical field

[0001] The invention relates to a method and device for regulating the flow of carbonized hydrogen liquefied gas. Background technique

[0002] In the past, a gas flow regulating device was known, which is used to store carbonized hydrogen gas in a liquid state in a pressure vessel with a specified volume, and discharge the gas from the container through an on-off valve equipped with a flow regulating mechanism to ignite, for example Used to release gas from smoking lighters, ignition appliances, portable gas cylinders, etc. Smoking lighters and other appliances are equipped with a pressure vessel that stores a small amount of petroleum gas in a liquid state, and a flow regulating member composed of a porous elastic foam such as a molded flat sheet (Moltplain) is compressed from the outside to adjust the vessel. The flow of the fuel gas inside is controlled and discharged through the switch valve, for example, it is sprayed from the burner and forms a flame ...
