Description
Technical field
The present invention relates to gas appliance security protection technology, relate in particular to a kind of smoke exhaust pipe of gas water heater safety guard.
Background technology
The safe handling of indoor type domestic gas-fired water heater is the significant problem of the sector always, numerous in using the accident of the casualties that domestic gas-fired water heater causes, and is all because smoke exhaust pipe not being installed or the nonstandard installation of smoke exhaust pipe causes.
Gas heater need to consume a large amount of air (or oxygen O when operation
2), the product great majority after burning in flue gas are CO
2cO with minute quantity.Winter operation is indoor often in relatively airtight environment, once gas heater operation, can not the flue gas after burning be drained into outdoor, flue gas can again enter water heater and combustion gas mixing is burnt, and because the continuous consumption of oxygen reduces, burning progressively becomes incomplete.Unburnt flue gas product is except CO
2to produce in a large number CO outward, so vicious circle, indoor CO concentration constantly raises, and causes the casualty accident of indoor occupant to occur.
In order to prevent that such accident from occurring; some enterprises have adopted the alarm safety device of CO alarm and gas heater interlock; once the generation of the indoor generation CO of water heater is installed; for example, when CO (: 0.02%) alarm action gathers finite concentration; send sound and light alarm; and the air valve of the gas heater being attached thereto is closed, stop burning, play safeguard protection effect.But any electronic product is average life problem all; the gas sensor of reporting to the police in particular for CO; by current best its life-span of technology, also only have 5 years, and always there is certain ratio in the inefficacy of components and parts, once malfunctioning its safety protection function of CO alarm just completely loses.And a large amount of implementations forced-ventilated or pressure supply and exhaust formula gas heater, utilize blower fan to force the flue gas that contains CO after burning effectively to drain into the outdoor generation that greatly reduces water heater CO intoxication accident, therefore forced-ventilated gas fast water heater is as long as correctly install smoke exhaust pipe by standard, and the indoor CO content of water heater long-play also can remain on extremely low safe range always.So can think forced-ventilated or pressure supply and exhaust formula gas heater are set up to CO warning device, can not stop the poisoning generation of CO completely, its necessity is insufficient.And guarantee smoke exhaust pipe standard correct install to be only thoroughly stop, because of gas heater operation, the poisoning key of CO occurs.Therefore, be necessary to invent a kind of safety guard that can reflect that smoke exhaust pipe is abnormal, effectively address this problem.
