If a house is not provided with a natural gas pipeline, the house must be purchased additionally, the storage of gas needs to be strict due to the flammable characteristic of the gas, and the metal barrel is a common method for storage, so the common purchasing method is to purchase a gas barrel filled with liquefied petroleum gas, however, although the gas barrel is convenient to use, problems still exist all the time, for example, when a brand new gas barrel is just connected, a jet of gas with strong air pressure rushes out at the moment of opening the air valve, and the gas with high air pressure value is likely to cause damage of a back-end pipeline (a pipeline between a gas device and the gas barrel) or damage of the gas device.

In addition, there is a common problem that it is difficult to find the broken position of the rear end pipeline close to the gas equipment (for example, the rear end pipeline close to the kitchen stove is easily shielded by the cabinet of the system kitchen ware), so that a large amount of gas is leaked to cause waste or even danger.
