Natural gas is the main fuel in people’s daily life, but few people know where the natural gas comes from or how it is transmitted to the cities and homes.
After natural gas has been extracted, the most common way is to use long-distance pipelines or tank trucks to transport liquefied natural gas. Due to the characteristics of natural gas, it cannot be stored and transported by direct compression, so it is usually transported through long pipelines or stored in tanks by means of liquefaction. Pipelines and trucks transport natural gas to large natural gas gate stations, and then, gas will be carried out to smaller gate stations in various cities.
In the urban gas system, the city natural gas gate station is the terminal station of the long-distance gas transmission line, also known as the gas distribution station. The natural gas gate station is an important part of the natural gas transmission and distribution system, and it is the gas source point of the transmission and distribution network in cities and industrial areas. Natural gas should be sent to the urban transmission and distribution network or directly to large industrial and commercial users only after property testing and odorization. This requires the use of filters, flow meters, electric gas pipeline valves, and other equipment to form a complete set of the gas processing system.
Finally, the gas will enter thousands of households through city gas pipelines. The device that records the gas consumption at home is the household gas meter, and the motor valves in gas meters are used to control the opening or closing of the gas supply. If the user is in arrears, the gas meter valve will be closed to ensure that no one is using the unpaid gas.
