Description
Technical field
The present invention relates to a kind of apparatus and method for being used to distribute fluid.Specifically, but simultaneously non-uniquely, the equipment by with
The allocation model that plurality of optional is provided is set to, such as including a kind of double-mode, it distributes fluid (for example, water) jet simultaneously
Or jet flow (stream) and fluid water smoke (mist) (jet).Certain embodiments of the present invention is related to a hand-held spray guns
(branch) and it is one fixing, for example on vehicle, nozzle for fire extinguishing.Present invention additionally comprises distribution fluid
The method of (for example, water), including for example under fire condition distribute fluid method.
Background technology
In order to stamp out a fire, hand-held or installation device, such as nozzle or spray gun, fluid source is generally attached to (for example, water
Source etc.), and the device is used to guide the fluid from source discharge.The device is usually provided with open/close mechanism, for controlling from spray
Mouth or spray gun discharge fluid.
Generally, fire nozzle or spray gun can be used for the jet flow of distribution fluid.These spray guns generally produce in annular O shapes jet flow
Raw relatively large drop.Fluid distribution form (pattern) can change between wide spray discharge pattern and concentration shape of plasma jet.
Generally, known spray gun only produces water smoke.Water smoke can be produced by some modes.A kind of such technology is to make
Drive fluid (for example, water) by microstome come atomisation with high pressure or super high pressure fluid source.Other methods are directed to use with
Paired interference jet flow produces water smoke.
Compared with the larger drop of the jet flow of conventional lance distribution, water smoke is considered as more effective firing-fighting medium, because
The larger surface-to-volume ratio of less water fog particle makes water smoke absorb more energy from fire.More water become
Steam, therefore the water produced to fire needed for effect same is less.As a result, therefore the size and flow of spray gun or nozzle can be
And reduce.
The system for only producing water smoke of prior art has uses relevant some shortcomings with it.Using very small hole
In the case of mouthful, they may easily be blocked.In addition, compared with the projection of jet or the larger drop of spray discharge pattern distribution,
Water smoke projection (that is, driving water smoke can suppress the distance of flame) is limited, therefore carries the fireman of handheld apparatus
Flame is must be closer to,, may be by for example, the system on vehicle to lead water to flame, or fixed system
The limitation of its coverage.Both of which is probably danger, all may threat to life.Therefore, in some cases,
Fireman is unwilling that using the spray gun mechanism for producing water smoke, although compared with jet or spray pistol mechanism, it is potentially put out a fire
It is more efficient.
The purpose of the present invention is to alleviate above mentioned problem at least in part.
Certain embodiments of the present invention aims to provide a kind of equipment, and it, which is configured as distribution fluid water smoke, to improve
