Natural gas refers to a mixture of hydrocarbon and non-hydrocarbon gases that are naturally trapped in subterranean formations, and in petroleum geology, oil field gas and gas field gas are commonly referred to. The natural gas is mainly used as fuel, is one of safer fuel gases, and can reduce the consumption of coal and petroleum by adopting the natural gas as energy, thereby greatly improving the problem of environmental pollution. And the natural gas is used as a clean energy, can reduce the emission of sulfur dioxide and dust by nearly 100 percent, reduce the emission of carbon dioxide by 60 percent and reduce the emission of nitrogen oxide by 50 percent, is favorable for reducing the formation of acid rain, relieves the global greenhouse effect and fundamentally improves the environmental quality.

With the improvement of the living standard of people and the enhancement of environmental protection consciousness, most urban residents adopt natural gas as fuel used in daily life, which is mainly embodied in a natural gas stove and a natural gas water heater.

The gas valve is a safety matching device for gas pipeline engineering, is used for cutting off, connecting and adjusting gas in pipelines, has good control characteristics and closing sealing performance, and can be divided into a shared pipeline valve, a home-entering main valve, a front valve of a stove, a gas stove valve and the like according to specific functions.

To ensure safe gas usage, natural gas suppliers often alert users to the use of gas valves to watch for regulations, such as: when the natural gas is not needed for a long time at home, the home-entering main valve is closed; and closing a front valve of the gas stove after the gas stove is used. In daily life, however, part of users only close the gas stove valve, and the main valve and the front valve of the stove are always in a normally open state, so that potential safety hazards are greatly increased.
