Description
Technical field
The utility model relates to a kind of integral type compressed air foam fire-extinguishing systems.
Background technique
Currently, many air compression foam fire extinguishing systems, have water pump, foam proportioning unit, air compressor, big gun to use
The composition such as air and liquid mixer, big gun flow spoiler, rifle air and liquid mixer, rifle flow spoiler, fire water monitor, fire-fighting lance, water pump
The pressure water source of offer flows through the foam solution in foam proportioning unit and system, and in defined ratio to be mixed to form foam mixed
Liquid is closed, the air provided by air compressor is added in big gun use or rifle air and liquid mixer, forms mixed liquor-compressed air two
Xiang Liu is spraying compressed-air foam by fire water monitor or fire-fighting lance after mixing evenly by big gun use or rifle flow spoiler, is reaching
To the effect of fire extinguishing and thermal insulation protection, substantially, which originally provides pressure water source with water altogether, through foam proportioning unit
The mixed liquor that foam solution in (negative pressure of vacuum sucking principle) and device is mixed to form in proportion is used in big gun or rifle gas-liquid is mixed
The air that is there is provided by air compressor is provided in clutch, forms mixed liquor-compressed air two phase flow, by big gun use or rifle with disturbing
It flows device and compressed-air foam is sprayed by fire water monitor or fire-fighting lance after mixing evenly, but the sucking of this negative pressure of vacuum is easy to produce
Pressure oscillation generates deviation to foam mixing liquid mixed proportion, and foam proportioner adjusts foams mix ratio to accurate
It is inconvenient, is not easy quickly to form the compressed-air foam for being suitble to scene of fire different phase, is also now to have some air pressures
Contracting froth fire extinguishing system uses compressed air as the power (pressure air that such as pressure cylinder or air compressor generate
Deng), foam solution is supplied with positive pressure, can be directly connected on penstocks road for foam liquid pipeline, water, foam solution are in pipeline
After mixing, directly in intervention compressed air line, stable two-phase flow is formed, though it can be kept away using positive-pressure type supply mode
It is passive to exempt from system pressure caused by negative pressure feeding, but foams mix ratio is still not easy quickly accurate adjustment, and is flowing
In the case where measuring very little, there is deviation in froth ratio；Current many air compression foam fire extinguishing systems are complicated for operation, be not easy into
Row operation, and the adaptability to changes that is in an emergency are weaker, greatly reduce extinguishing operation efficiency, bungle the chance of winning a battle, to lives and properties
Cause immeasurable loss.
