Description
Technical Field
The utility model belongs to the technical field of fire-fighting equipment, concretely relates to temperature sensing automatic fire extinguishing starter.
Background
At present, the following three control modes are mostly adopted in the field of domestic and foreign automatic fire extinguishing control: the active fire alarm device senses smoke change firstly and senses temperature change secondly when a fire breaks out, then a control system judges whether the fire breaks out or not, and sends an ignition signal to a fire extinguishing device and gives an alarm if the fire breaks out; otherwise, the detection is continued. And secondly, the active ignition starter is used, when a fire disaster happens, the ambient temperature of a detection head of the active ignition starter changes, and after the set temperature is reached, the temperature control metal in the starter is communicated with an ignition circuit, so that the electric ignition element ignites. Thirdly, a thermosensitive wire is adopted as a starter, when a fire disaster happens, the gunpowder in the thermosensitive wire senses that the temperature changes to spontaneous combustion or the gunpowder is directly ignited by flame, the thermosensitive wire burns to transfer fire, and then the initiator in the fire extinguishing device is initiated.
