[0002] Natural gas is one of the three major energy sources for human beings. It has a wide range of applications, such as the use of natural gas for power generation, chemical industry, residential fuel, and vehicle fuel. At present, natural gas is mainly transported in the form of pipeline transportation, liquefaction For transportation and high-pressure bottled transportation, pipeline transportation is basically adopted in the chemical industry. The input end of the pipeline is connected to the natural gas source, and the output end of the pipeline is connected to the consumer equipment. A valve is arranged at the input end to control its on-off. If it is necessary to deliver natural gas to the consumer equipment, open the valve; if it is not necessary to deliver natural gas to the consumer equipment, close the valve. Leakage occurs during pipeline transportation, which is very prone to the danger of explosion, especially in a closed space with poor ventilation. In order to improve the safety of natural gas pipeline transportation, the inventor designed a , easy to operate and use, and low production cost for the automatic gas leakage automatic circuit breaker system used in the safe transportation of natural gas
