Description
Technical field
The utility model relates to a kind of foam system extinguishing system, and particularly a kind of expansion rate that can accelerate foam solution makes foam volume larger, and the relative foam system extinguishing system that more improves of amount of expansion.
Background technology
When do in narrow and small lane, when the tunnel that traffic congestion is serious or national highway generation fire alarm, because general fire fighting truck can be because car body be too huge, the fire scene that often can't drive in a vehicle to above-mentioned is carried out the task of the fire extinguishing disaster relief, so only can allow the fireman bear or the fire-fighting equipment of carrying portable goes to the on-the-spot disaster relief, because the cause of the extinguishing fluid finite capacity that the lightweight fire-fighting equipment contains, cause fire extinguishing effectiveness relatively relatively poor, therefore, then have and a kind ofly can load more extinguishing fluids and ask the city with the fire-fighting locomotive of relevant fire-fighting equipment, its representative patents is shown in TaiWan, China M409854 new patent " parking supporting structure of fire-fighting locomotive " and M427163 new patent " fire motorcycle system ".In addition, known compressed air foam fire extinguishing system is to coat burning things which may cause a fire disaster and block oxygen with foam solution, so the fire extinguishing effect is much better than the fire extinguishers such as the general aqueous solution, carbon dioxide and dry-chemical fire extinguishing medicament, therefore has been widely used on various fire-fighting vehicle and the fire-fighting locomotive.
