Furthermore, the indoor safety of gas is a social problem, and the government and management departments have always attached great importance to it. Gas companies have also taken many active and effective measures and achieved obvious results. However, it should be noted that the level of gas safety depends on the development level of social productivity and the quality level of people. As far as the current indoor gas safety situation is concerned, there are still some problems to be solved urgently. The main causes of gas leakage are as follows:

1. Pipeline leakage—mainly caused by corrosion and perforation of the outer wall of the pipeline, and generally occurs in relatively damp wall-through and floor-through parts. In addition, unauthorized use of indoor pipelines as load-bearing supports and random dismantling and modification of pipelines will also cause leakage at threaded joints.

2. Valve leakage - due to corrosion, wear and aging of sealing materials.

3. Leakage of gas meters - mainly caused by the aging of intermediate shaft seals, generally concentrated on old meters that have been used for a long time, and are easily affected by temperature changes.

4. Leakage of the meter joint - caused by the aging of the rubber pad.

5. Appliance leakage - there are two situations. One is the leakage of the appliance when it is not in use, which is mostly related to the lax closure of the valve body caused by the tempering of the appliance and impurities. Another situation is the runaway caused by improper operation and use of the desktop stove (without flameout protection function), such as ignition error, halfway flameout, and straight running caused by other reasons.

6. Rubber hose leakage - there are also two situations, one is the air leakage of the rubber hose or joints caused by aging cracks, and the second is the open leakage caused by the aging and hardening of the rubber hose and loosening and falling off under the action of external force.

At present, there are many users who use natural gas. Although natural gas itself is non-toxic, its leakage indoors will reduce the concentration of oxygen in the air. When the natural gas content reaches 10%, people will feel difficulty in breathing. No matter how high the concentration is, there will be a danger of suffocation. Leaked natural gas reaches an explosive concentration in a confined space, and will explode when exposed to an open flame. The destructive force of the explosion is related to the volume, concentration and structure of the mixed gas. The main reasons for the loss and damage caused by the explosion are the high temperature, high pressure and shock wave generated. After calculation, the destructive power of a natural gas explosion in a 100-square-meter residence is equivalent to that of a 100kg TNT explosive explosion.

The patent of the invention has a strong protective effect on gas leakage, can effectively protect the safety of users, and has good social benefits.
