Description

Technical Field

[0001] The utility model relates to the technical field of gas filling equipment, in particular to a gas filling device. Background Art

[0002] Gas is a general term for gaseous fuels, which can burn and release heat for use by residents and industrial enterprises. There are many types of gas, mainly natural gas, artificial gas, liquefied petroleum gas, biogas, and coal-to-gas. The most common is natural gas, and liquefied natural gas, whose main component is methane, is manufactured by first purifying the natural gas produced by the gas field, and then transporting it by liquefied natural gas ship after a series of ultra-low temperature liquefaction. After burning, liquefied natural gas causes very little air pollution and releases a lot of heat, so liquefied natural gas is a relatively advanced energy source. However, in the process of transporting liquefied natural gas, gas tanks are generally used to store natural gas. If it is shaken violently, the evaporation of liquefied natural gas will be accelerated, which will cause the gas pressure in the gas tank to rise rapidly and exceed the set safety pressure, causing the tank to be over-pressurized, posing a safety hazard.
