Description
Technical field
The invention belongs to the fire prevention field, be specifically related to a kind of fire-fighting spraying head and pipe fitting connector leak stopping device.
Background technology
According to the regulation of country's " Code for fire protection design of buildings ", the use that the industry and the fire-fighting systems of civil buildings are all a large amount of the fire-fighting spraying head.The glass marble of spray head or fusible link when shower nozzle is heated, because the working solution in the glass marble has an effect, burst spheroid or owing to the fusing of fusible link, come off and open water jet, fire water sprays along water jet, plays the effect of fire extinguishing.
Spray head is in closed condition at ordinary times, and the pipe fitting interface that is attached thereto the evaporating, emitting, dripping or leaking of liquid or gas phenomenon should not occur at air-tight state yet.But, might cause all that the fire-fighting spraying head is unexpected to be erupted or evaporating, emitting, dripping or leaking of liquid or gas appears in the pipe fitting connector because unexpected factor and accident (like artificial destruction, accidental impact, closely heat source near, low temperature bursting by freezing, product quality problem etc.).In case this type accident takes place, conventional processing method is: the notice fire protection control room, the fire-fighting spraying water pump is shut down; Close the water inlet total valve of this fire-fighting system, open emptying valve simultaneously, with the whole emptyings of water in this fire-fighting system pipeline; After the accident spray head of treating stops water spray, change spray head.This process needs dozens of minutes at least, during the fire water that sprayed of accident spray head, not only to causing direct and indirect loss in the building, simultaneously,, also be great potential safety hazard because whole spraying system of fire fighting all is in halted state.
Especially large tracts of land is used the place of spraying system of fire fighting; Like warehouse, office building, public place of entertainment, airport, station etc., spraying system of fire fighting should prevent unplanned situation out of service as far as possible, so; In case meet accident; Must leak stopping in the shortest time, maybe with the fire water of ejection, water pipe temporarily drains into sewerage.
Summary of the invention
