Description
Technical field
The invention belongs to household appliance technical field, be specifically related to a kind of gas leakage valve-closing ventilating system.
Background technology
During family's combustion gas uses, the situation of gas leakage can occur unavoidably.Gas leakage will set off an explosion fire,
, there is the biggest potential safety hazard in the contingencies such as personnel's poisoning.Especially when family is old solitary people or child, it is easier to
Cause related accidents.Therefore, detect gas leakage, and carry out relevant treatment in time and be just particularly important.
It is (main that the combustion gas that family uses is substantially natural gas (predominantly methane), liquefied petroleum gas (propane) and water gas
Carbon monoxide to be).The ultimate value lower limit that fires of these three combustible gas is respectively concentration 5%, 4% and 12.5% in air, equally this
A little aerial concentration of fuel gas the most all can make in people in the environment of reaching to a certain degree or to be for a long time in low concentration
Poison.
Traditional fuel gas leak alarm systems is that gas concentration carries out local warning when exceeding threshold values in air being detected
And close valve.
The weak point of this method is:
(1) combustion gas leaked will can not get effectively discharging, and still there is potential risk；
(2) gas leakage problem can not be notified user by local warning timely and effectively.
