Description

一种喷雾装置 本申请要求两项中国专利的优先权， 第一项是 2008年 7月 18日提交 中国专利局、申请号为 200810071432.6、发明名称为"自驱动旋转喷洒装置" 的中国专利申请的优先权； 第二项是 2009年 3月 9日提交中国专利局、 申 请号为 200910111270.9、 发明名称为"喷射推动旋转式喷雾头"的中国专利 申请的优先权， 两项专利申请的全部内容通过 1用结合在本申请中。 技术领域
本发明涉及喷洒技术， 尤指一种喷雾装置， 该喷雾装置主要应用于消 防领域，尤其是涉及自动灭火系统中使用的喷雾装置，也可用于喷雾除尘、 喷雾干燥、 喷雾喷灌等其它领域。 背景技术
一些旋转喷雾如由旋转盘成膜造成的离心喷雾， 它们的旋转动力靠马 达驱动， 但马达驱动系统结构复杂、 体积大还需要额外提供旋转动力； 某 些靠流体驱动的旋转喷洒装置， 如轮转喷灌装置， 都是单一利用射水反力 或靠水流冲击转轮叶片带动喷嘴盘进行旋转喷洒喷雾的， 如专例 03245269.1、 99216638.1 , 由于它们的体积和转动惯量较大， 旋转不快， 喷 洒或喷雾不细， 难以小型化、 不能满足细水雾灭火喷头的小巧、 强力和细 雾化的严格要求。
消防领域中传统的水雾喷雾头或细水雾喷雾头是固定喷雾头， 由于受 结构和体积要求的限制， 它们很难做成旋转喷头， 只能固定喷雾， 因此， 在保护区存在喷射死角。解决办法之一是旋转喷雾，这需要用旋转喷雾头。 申请号为 200520091525.7的中国实用新型专利公布了一种用水冲击旋转分 叶轮的大流量喷头， 它属于传统溅水转动喷头， 对解决均勾喷洒问题有一 定的作用， 但它的喷洒水滴大、 不能成雾状。 申请号为 200510034232.X的 中国发明专利申请公布了一种旋转式喷射消防灭火枪， 它的水嘴体前端设 风叶状排列的斜缝出水口， 靠斜缝喷水反向冲力使水嘴体旋转。 它可以转 动均匀喷洒， 但它的结构较大， 旋转较慢， 所喷洒的水流和水滴也大， 不 能艮好成雾。 上述前案都不适于灭油火、 精密电子设备等类火， 灭这类火 需要使用泡沫喷雾、 尤其是细水雾比较合适； 但目前的水喷雾、 泡沫喷雾、 细水雾喷头都是固定喷雾头， 不能旋转， 且该喷雾头的喷雾性质基本属于 局部灭火， 局部灭火的要求是快速把水雾直接喷射到着火物各处， 并使着 火物全面均匀覆盖； 而固定喷雾头的喷雾流在空间内的分布是不均匀的， 难以对着火物各处做全面均匀覆盖， 这会影响灭火速度和可靠。
细水雾灭火是靠水雾微滴相变机理进行灭火的新技术，它仅用传统水喷 雾和洒水灭火用水的几十分之一即能快速灭多种大火。 lKg微水滴在火场 从室温 20C升到 1600K时的蒸发吸热量高达 5893KJ,同时汽化成 1.7立方 米惰性的水蒸气， 但产生这种迅速蒸发急速降温和排氧窒息灭火的优异性 能力的前题是： 细水雾必须快速大量产生并能在火场空间中充分吸热迅速 蒸发， 而水滴的蒸发速率和吸热效率与其直径的平方成反比，： 如 0.5mm 粒径水滴蒸发时间约为 0.27秒而 0.05mm粒径微水滴蒸发时间仅为 0.0027 秒，所以超细化雾化并和火场热烟气充分参混是细水雾能高效灭火的关键。 现有压力雾化灭火喷头用小圓孔固定喷雾模式， 它存在难以克服的障碍首 先是流量和细雾化的矛盾， 因为细雾滴只能从小孔径喷口产生， 然而喷雾 的流量与孔径平方成正比，这使得细雾化和大流量的矛盾难以解决;其次是 细雾化和喷雾动量的矛盾， 喷雾越细动量越小喷得越近， 难以进入火场空 间， 另外消防用细水雾喷头的性能、 体积和外观都受到严格限制。 由于上 述矛盾一直难以解决， 因此现有消防喷雾头性能不理想， 不能全面满足细 水雾灭火的高要求。 难以实现全空间掩没灭火。 与细水雾灭火要求相似的 还有喷雾干燥和喷雾燃烧， 它们喷雾的实质目的其实也是为了使液体快速 大量蒸液发， 为此不但需要细雾化， 还需大动量使液体分散到全空间与空 气完全混合， 以便使液滴与空气充分接触从中吸收更多热量， 达到必需的 气化潜热量才能蒸发变成气体， 旋转喷雾能够提供使水雾快速蒸发的传热 传质条件。 发明内容
本发明喷雾装置的目是为解决上述喷雾的矛盾难题， 尤其是针对消防 喷雾喷头的不足给出一种旋转喷雾装置， 使其能产生大量细水雾并迅速蒸 发、 急速降温， 同时生成大量隋性气体排氧窒息灭火以达到迅速强力灭火 目的。
因此， 本发明旋转喷雾对于灭火， 提高灭火度非常重要， 但当前的喷 洒装置还不能满足现实需要。 在喷雾除尘、 喷雾干燥、 等其它领域中，也需 要形成的均匀的雾状， 以提高其除尘、 干燥或其他效果。
本发明所欲解决的第一个技术问题在于提供一种利用偏心喷雾口的喷 雾射流反作用力造成自动旋转的喷射推动旋转式喷雾装置， 且该喷雾装置 在中低压下工作也能够解决大面积的均勾喷雾和细雾化的难题。
为达成上述技术问题， 本发明的技术解决方案是：
一种喷射推动旋转式喷雾装置， 包括中空座体及可相对座体转动的喷 头体， 座体设有座体腔， 座体腔入口螺紋连接有外部输入流管； 喷头体内 部设有流体通道， 外部设有喷雾口， 各喷雾口都与流体通道相通， 流体通 道与座体腔入口相通； 喷头体的喷雾口中至少包含两个以喷雾装置为轴对 称的偏心喷雾口， 偏心喷雾口的中心线与喷雾装置中心线不相交， 每个偏 心喷雾口的喷雾流反作用力都对喷头体产同向旋转力矩， 其旋向与喷雾装 置上连接螺紋的旋紧方向一致； 喷头体与座体之间具有转动配合面， 利用 透入转动配合面间隙的流体对转动配合面进行润滑， 把转动配合面中可能 外泄漏液的至少一个配合面间隙设计成环缝喷雾口， 少量流体经环缝喷雾 口参入喷雾。

所述喷头体设有中央套形孔， 座体设有空心轴， 喷头体以其中央套形 孔可转动地套在座体空心轴上， 空心轴孔上设有与轴孔同心的缩孔， 在缩 孔下游空心轴壁上设有与喷头体内部流体通道相通的连通孔， 缩孔的出口 由被一热敏支撑组件顶紧的活塞件封堵、 并阻断座体腔入口与连通孔的通 路， 热敏支撑组件的基端旋塞固定在座体空心轴孔的端部， 基端旋塞的圓 台阶与座体外圓台阶夹住喷头体上下环面， 为喷头体做轴向定位， 构成闭 式旋转喷雾装置； 喷头体下环面与座体外圓台阶面之间形成的转动配合面 间隙环缝即为所述环缝喷雾口， 利用透入转动配合面间隙的流体对转动配 合面进行润滑， 当喷雾转动时少量流体经过该环缝喷雾口参入喷雾， 在喷 头体环面或座体外圓台阶面上可设放射状细沟， 它最好呈切向放射状， 并 且细沟入口截面大， 出口截面小， 细沟能促进漏液喷雾和旋转。
所述喷头体设有中央套形孔， 座体设有空心轴， 喷头体以其中央套形 孔可转动地套在座体空心轴上， 空心轴壁上设有与喷头体内部流体通道相 通的连通孔， 内设中心雾化芯的旋塞固定在座体空心轴孔的端部， 旋塞的 圓台阶与座体外圓台阶夹持喷头体上下环面， 为喷头体做轴向定位； 在旋 塞的圓台阶面与喷头体上环面之间可设平面转动密封， 喷雾时在喷头体下 环面与座体外圓台阶面之间易形成间隙环缝， 该间隙环缝及其外周的扩口 即为所述环缝喷雾口， 利用透入转动配合面间隙的流体对转动配合面进行 润滑， 当喷雾转动时少量流体经过该环缝喷雾口参入喷雾， 在喷头体环面 或座体外圓台阶面上可设放射状细沟， 它最好呈切向放射状， 并且细沟入 口截面大， 出口截面小， 细沟能促进漏液喷雾和旋转。
所述喷头体周围设有雾化芯及偏心喷雾口， 喷头体中央设有入口管， 入口管可转动地被套置在座体的内孔中， 座体内孔上和出口处分别设上环 面的下环面， 喷头体入口管的进口端外周设上圓台阶或上圓环和挡圈， 露 于座体内孔外的喷头体入口管出口端外周设下圓台阶， 上、 下圓台阶与座 体内孔上环面的下环面共同为喷头体做轴向定位， 在露于座体内孔外的喷 头体下圓台阶和座体出口环面之间形成转动配合面间隙环缝， 设计成所述 的环缝喷雾口， 环缝喷雾口的间隙环缝内侧还可另设环形槽， 环形槽经一 引流孔连通流体通道； 另外喷头体的底面可设喷雾口。
当釆用本发明的座体外套在喷头体入口管上的结构时， 转动配合面的 外泄漏液间隙仅为一圈间隙环缝， 它即设计为环缝喷雾口； 当釆用本发明 的喷头体外套在座体空心轴上的结构时， 转动配合面的间隙环缝有上下两 圈， 此时若仅将一圈设计成环缝喷雾口， 对另外一圈间隙环缝应设转动密 封。
所述喷头体为外形带截头多面锥或柱形或空间母线回转形体的喷头 体， 该三种喷头体在用于闭式旋转喷雾装置时为例外， 其余情况底部可以 设有喷雾口； 该三种喷头体周围都设偏心喷雾口， 其中空间母线回转形体 的喷头体设的偏心喷雾口可为带偏心楔面槽眼形孔的斜喷雾口、 或为带偏 心楔面槽细缝的斜喷雾口。
所述喷头体为带有近似十字形支臂或复合方形体的喷头体； 在各支臂 背向旋转方向的四个侧面上设有偏心喷雾口， 在喷头体端面或和各支臂端 面可设喷雾口； 在方形体各侧面、 具有相同偏心距的位置上可设有偏心喷 雾口， 在方形体底面可设有喷雾口。
所述喷头体上设有的喷雾口可连带雾化芯腔， 雾化芯腔内设雾化芯， 雾化芯设有旋流通道， 使压力流体在雾化芯腔中旋转再经喷雾口成雾； 所 述雾化芯至少包括带有单级旋流腔或旋流子或涡旋流叶片的雾化芯或双级 旋流芯并带有环缝或串级喷雾口的雾化芯， 带雾化芯的喷头内可设有过滤 器。
所述内设各种雾化芯的雾化芯腔连带的喷雾口为斜喷雾口， 它是与雾 化芯腔的收缩锥孔斜连接的喷雾口， 即雾化芯腔的收缩锥孔中心线与喷雾 口中心线斜交叉。
所述的喷雾口包括无转矩的普通喷雾口和对喷头体有转矩的偏心喷雾 口； 偏心喷雾口是喷雾口中心线偏离喷头体中心线的喷雾口， 偏心喷雾口 可为不带雾化芯的偏心喷雾口、 或为设有雾化芯的雾化芯腔所连带的偏心 喷雾口； 雾化芯腔所连带的偏心喷雾口包括喷雾口与其雾化芯腔同心的偏 心喷雾口和与雾化芯腔不同心的斜喷雾口以及雾化芯斜置于雾化芯腔座内 形成的斜喷雾口。
釆用上述方案后， 由于本发明喷头体的流体通道输出端设置了至少两 个具有偏心矩的偏心喷雾口， 当偏心喷雾口喷射流体时， 流体喷射的反作 用力将对喷头体形成转矩， 推动喷头体旋转， 并带动喷头体上的所有喷雾 口 （包括无转矩普通喷雾口及偏心喷雾口）一起转动， 此结构在中低压的 情况下即可令喷头体旋转，从而得到快速且大面积的均勾喷雾效果。此外， 本发明可通过改变喷雾口的形状（如设置眼形孔喷雾口 ),或直接在喷头体 上嵌固各种雾化芯， 即可得到所需要的雾化喷洒效果。
本发明提供的喷雾装置比传统旋转喷头的显著进步： 受结构限制现有固定消防洒水喷头， 水滴太大、 水迹污染大且喷洒不 匀； 现有的水雾和细水雾喷头基本也都是固定的， 固定式细水雾喷头虽然 喷雾细但喷雾动量小， 尤其是在中低压下喷不远难以进入火焰深处； 固定 消防喷头在保护区都存在喷射死角影响灭火效果， 而现有旋转喷头基本都 仅可旋转喷洒， 而不能旋转喷雾而且旋转喷洒的水滴和水量太大， 许多场 合不适合使用； 个别能喷雾的旋转喷头结构复杂。
本发明旋转喷雾装置的显著特点是结构大为简化： 它不需附加机构和 外动力、 不需旋转密封， 就能够自驱动、 自润滑， 仅用几个零件组装起来 即可组成旋转喷雾装置。 本发明的实质性特点是本喷雾装置给出了大流量 超细雾化机构和几种复合自旋机构组成的高速旋转压力喷雾装置， 它使喷 雾灭火能力显著提高： 它的喷雾不存空白盲区， 本装置旋转喷雾的雾滴具 有喷头转动的离心惯性力和切向速度、 造成空气的强烈扰动并与之强烈碰 撞磨擦和参混， 因而能显著促进细雾化并迅速蒸发成大量水蒸气， 具有急 速降温和排氧窒息灭火的突出优点和强力灭火效果。
本装置不但能提高雾化速度和流量， 还能增大喷雾动量， 因而在中低 压下就能进入火场火焰热气中， 有良好的旋转喷雾灭火效果； 本发明的突 出优点是给出了多种适当的喷头体、 雾化芯或 /和喷雾口， 并能加以灵活组 合以适应对喷雾流量、 细度、 喷雾角度的不同要求， 尤其既可做成开式旋 转喷雾装置又可做成闭式旋转喷雾装置， 能适用于开式灭火系统又可适用 于闭式灭火系统和多种场合的不同需要； 本发明的另一突出优点是把本来 有害漏液变为利用它做转动润滑和喷雾。 在座体与喷头体之间的转动配合 面必然有转动间隙， 这会产生有压流体外泄漏的问题， 现有技术解决外泄 漏是必设旋转密封防漏， 这使喷头结构复杂化且增加旋转阻力， 不利于转 动喷雾， 本发明一反常规的偏见， 提出的新解决方案是利用和助长这种外 泄漏， 即不设或少设密封相反利用漏液间隙或和增设放射状细沟作为漏液 喷雾口， 变害为利使漏液参入喷雾， 这特别有利于简化喷雾装置结构并提 高旋转喷雾性能。
本发明喷射推动旋转式喷雾装置品种多样， 很适合多种用途的喷雾灭 火。 本发明不但较好地解决了旋转喷雾问题， 而且使复杂体大的旋转式喷 头（一般需设滚动轴承）变得简单易行， 可明显改善喷雾质量和灭火效果。 因而本发明适合于细水雾或水喷雾灭火， 它为绿色环保的中低压细水雾灭 火系统提供了一种新式的关键元件。
为使喷雾装置能够在压力更低的环境下应用， 同时提高喷雾装置喷雾 的可靠性， 本发明所欲解决的第二个技术问题在于提供一种利用水力驱动 方式做自旋转喷雾的自驱动旋转喷雾装置， 使其在中低压下能够快速大面 积的均勾喷雾。

所述的驱动机构还包括设置于喷头体外周的至少两个偏心喷雾嘴， 喷 头体形状和其上设置的喷雾嘴或喷雾头形状和分布大体为绕喷头体轴线的 空间旋转对称形， 且偏心喷雾嘴的喷流中心线在喷头体轴线的垂直平面内 的投影与喷头体轴心具有偏心距， 且偏心喷雾嘴的喷流方向与叶轮推动喷 头体的转动方向相反。
所述被击式叶轮为具有接受旋流冲击的斗形叶片或板形叶片的叶轮， 与之对应在叶轮外周的座腔内固定一圈旋流喷雾口， 叶轮固定于喷头体的 输入端上或固定在与喷头体固定连接的连接组件上。
所述被击式叶轮为带有倾斜叶片的轴流式或半轴流式浆形叶轮， 叶轮 固定于喷头体的输入端上或固定在与喷头体固定连接的连接组件上。
所述的连接组件为滚动轴承、 钢珠组件、 或旋转滑动轴承。
所述连接组件为旋转接头， 旋转接头由带输入输出口的内外接头、 轴 承装置及密封件构成； 所述座体固定连接旋转接头内接头， 或者两者合而 为一， 所述喷头体与旋转接头外接头固定连接； 所述被击式叶轮固定于喷 头体的输入端上或固定在与喷头体固连的旋转接头外接头上， 叶轮接受流 体流动推力产生旋转扭矩， 带动旋转接头及喷头体一体转动。
所述喷头体为至少一个十字形体， 十字形体内设有十字形流体通道， 在喷头体的每个十字臂的逆旋转方向均设有一个偏心喷雾嘴， 每个偏心喷 雾嘴均与流体通道呈一定角度相通。

更具体而言， 本发明的优点是利用灭火流体自身能量转动喷头体而不 需外力驱动， 结构简单， 尤其可使固定喷雾头的喷雾质量和灭火效果大为 改善。 而旋转喷雾的好处是能克服以下缺陷： a )受结构限制现有固定喷头 喷洒不勾、 甚至在保护区存在喷射死角； b )现有固定喷雾头的喷洒冲量有 限， 尤其是细水雾喷雾头需要喷细雾、 水滴很小， 在中低压下喷不远， 这 种小动量喷雾难以进入火焰深处、 影响灭火效果。 而旋转喷雾恰恰最能克 服固定喷头的上述两个严重缺点。 旋转喷雾是全空间轮转喷洒， 不存空白 盲区， 而且旋转喷雾的雾滴具有喷头转动的离心惯性力、 因而喷得远、 喷 雾动量大。本发明提供的自驱动旋转喷雾装置可以是水喷雾型、细水雾型、 气水雾型、 泡沫型、 泡沫喷雾型等多种消防旋转喷雾头， 因而本发明适合 于大空间灭火及其它水系灭火使用， 也为绿色环保的中低压细水雾灭火系 统应用开拓了新路。 再者， 本发明所述的旋转喷雾装置可使用水、 油或其 它液体， 也可使用气、 液两流体或气、 液、 粉多相流等工作介质， 可用于 其它喷雾领域， 因而适用范围广。

具体实施方式
下面结合附图和具体实施例对本发明作进一步详述。
实施例 1 : 如图 1、 图 1-1及图 1-2。
本实施例所述的喷射推动旋转式喷雾装置为具有套式喷头体的喷射推 动旋转式闭式喷雾装置，其主要包括座体 110及喷头体 120 (如图 1所示）。 其中：
所述的座体 110内部中空，其一端为入口 111 ,入口 111内设有过滤器 9, 入口 111外设有螺紋与输入流管（图中未示出）相连接， 座体 110还设 有空心轴 112, 空心轴 112轴向具有壁上设有斜通孔形成的旋流喷口 114。
所述喷头体 120为转子体， 其具体形状可为多种， 本实施例中， 该喷 头体 120为带中心通孔的截头多面锥， 喷头体 120可转动地套在座体 110 的空心轴 112上， 并在喷头体 120和空心轴 112之间形成环形腔， 喷头体 120 内部设有流体通道 121 , 该流体通道 121 的输入端通过环形腔与座体 110空心轴 112上的一圈 4个旋流喷口 114相通， 在喷头体 120环形腔的 周壁上均布设有雾化芯腔 124, 雾化芯腔 124内置雾化芯 6,且带有能产生 偏心喷雾流的斜喷雾口 123 , 形成偏心喷雾口； 所述雾化芯 6外周设斜槽 的雾化芯 6, 雾化芯 6的内端为凸出部， 该凸出部露在雾化芯腔 124入口 夕卜， 并凸出于所述环形腔内壁， 斜喷雾口 123的中心线在垂直于喷头体轴 心的平面上的投影线与喷头体 120中心具有偏心距离， 构成偏心喷雾口。 且各斜喷雾口 123的设置方向应使喷头体 120同向转动。
在有压力流体输出时， 偏心喷雾口 123斜喷雾口 123产生的各偏心喷 雾流的反作用力对喷头体 120产生相同旋向的扭矩； 优选的， 扭矩的旋向 与入口 111的外设螺紋的旋紧方向相一致。 同时， 旋流喷口 114向环形腔 输出旋流， 旋流冲击雾化芯 6的内端凸出部， 使喷头体 120旋转， 因此， 带有雾化芯 6凸出部的喷头体环形腔内壁形成叶轮， 该叶轮产生的扭矩与 偏心喷雾口产生的扭矩方向相同， 二者的共同作用使喷头体 120旋转。
此外， 所述座体 110的空心轴 112之内设有缩孔 113 , 缩孔 113的出 口由活塞件 131封堵， 并阻断座体 110入口 111与喷头体 120内部流体通 道 121的连通； 所述活塞件 131由一热敏支撑组件 130顶紧、 热敏支撑组 件 130的基端旋塞 132固定在座体 110空心轴 112的孔端部，基端旋塞 132 的圓台阶面与座体 110圓台阶面夹住喷头体 120上环面和下环面， 共同为 喷头体 120做可转动的轴向定位， 构成直立的闭式旋转喷雾装置。
本实施例的工作过程为： 当发生火灾而导致室内温度到达设定值时， 热敏支撑组件 130脱落， 活塞件 131失去支撑力， 在入口 111流体压力作 用下脱离缩孔 113的出口， 从而使座体 110的入口 111与通孔 114相通； 流体由座体 110的入口 111经过空心轴 112内部的一圈旋流喷口 114旋流 进入喷头体 120的流体通道 121的环形腔， 并使喷头体的孔式叶轮旋转， 再经过雾化芯腔 124内的雾化芯 6, 最后由雾化芯 6的斜喷雾口 (即偏心 喷雾口 123 )喷出， 斜喷雾口在喷流同时， 产生偏心喷雾流； 孔式叶轮的 内驱动力与偏心喷雾口的外驱力共同促使喷头体加速旋转， 这种高速旋转 喷雾与周围空气强烈碰撞磨擦和参混强力促进流体的细雾化和迅速蒸发， 形成浓密细雾云， 进而达到均勾喷雾化的效果。
再者， 在所述的座体 110外圓台阶面与喷头体 120下环面之间， 以及 在基端旋塞 132的圓台阶面与喷头体 120上环面之间， 具有上间隙环缝和 下间隙环缝， 形成转动配合面； 可在上间隙环缝处设密封， 仅将下间隙环 缝设计成环缝喷雾口 140, 也可使上间隙环缝和下间隙环缝都设计成环缝 喷雾口。 在供水时， 流体透入转动配合面对其进行润滑， 使喷头体 120可 顺利地在座体 110上旋转， 少量流体通过转动配合面的环缝喷雾口 140参 入喷雾， 且由于间隙较小， 可形成雾状喷洒效果， 该环缝喷雾口 140外周 可有扩张小口 142, 也可不具有扩张小口 142。
再如图 1-1及图 1-2所示， 其是本实施例 1闭式旋转喷雾装置的另一 种形式的喷头体 120'。 所述喷头体 120' 带有近似十字形的支臂 125' , 它 的中心通孔可转动的套在座体 110的空心轴上。 在其各支臂背向旋转方向 的四个侧面且偏离中心的位置上设有所述的偏心喷雾口 123' , 它与其内的 流体通道 121' 相连通； 或者设置与流体通道 121' 相通的雾化芯腔， 用以 固定具有直喷雾口的雾化芯 6, 雾化芯 6的直喷雾口相对雾化芯 6虽然为 非偏心设置， 但由于雾化芯 6相对于喷头体 120' 为偏心设置， 因此雾化 芯 6的直喷雾口即构成所述的偏心喷雾口 123'。 各支臂 125' 的外端面或 者底面还可设偏心喷雾口或 /和无偏心的普通喷雾口 122'。 所述的喷头体 120' 外形也可是带有多面锥形或柱形的喷头体。
另外， 所述喷头体 120' 下环面上还可设有若干放射状细沟 141' , 放 射状细沟 141' 最好呈切向放射状， 并且入口大， 出口小， 该喷头体 120' 下方带放射状细沟的环面与座体外圓台阶面配合， 即形成所述转动配合面 的环缝喷雾口， 出水时所述放射状细沟 141' 向外导流， 增加环缝喷雾口 的喷雾。
上述实施例 1还可变型为： 具有套式喷头体的喷射推动旋转开式喷雾 装置， 参见图 1。
在实施例 1的闭式喷雾装置上去掉活塞件 131、缩孔 113、热敏支撑组 件 130及基端旋塞 132; 然后在座体 110空心轴 112孔的端部固定一内设 中心雾化芯和中心喷雾口的旋塞 （未予图示）， 旋塞的圓台阶与座体 110 外圓台阶夹持喷头体 120的上环面和下环面， 为喷头体 120做轴向定位， 此时雾化芯腔及偏心喷雾口的设置方向应与中心喷雾口的方向相协调， 以 使它们的喷雾方向符合灭火方向； 其余不变， 即可构成具有套式喷头体的 喷射推动旋转开式喷雾装置。
上述闭式与开式的概念即为： 当有热敏等组件时为闭式， 当无热敏等 组件时为开式。
实施例 2: 如图 2、 图 2-1及图 2-2所示。
本实施例所述的喷射推动旋转式喷雾装置同样包括座体 210及喷头体
220。 其中：
所述的座体 210内部中空，其外壁设有螺紋与输入流管（图中未示出） 相连接， 座体 210的内孔 212上和出口处分别设上环面 215、 下环面 216。
所述的喷头体 220上方设有入口管 226, 下方设有复合方形体 225 ,该 入口管 226可转动地套置在座体 210的内孔 212中。喷头体 220入口管 226 的进口端外周设上圓台阶 227和卡圈 224, 露于座体 210内孔 212外的喷 头体 220外周顶圓环形成下圓台阶 228和上圓台阶 227; 上圓台阶 227和 下圓台阶 228夹持座体 210内孔 212上环面 215、 下环面 216, 为喷头体 220做轴向定位。 在露于座体 210内孔 212外的喷头体 220下圓台阶 228 和座体 210下环面 216之间形成间隙环缝， 该环缝设计成环缝喷雾口 240, 形成转动配合面，该环缝喷雾口 240上还可设切向放射状细沟 241 (见图 2 的 E-E向剖视示意， 即图 2-2 ), 环缝喷雾口 240内侧还可另设环形槽 243 , 该环形槽 243直通流体通道 221的引流孔 244, 放射状细沟 241和引流孔 244可以增加环缝喷雾口 240的漏液喷雾效果。
另外， 所述的喷头体 220的入口管 226内设有过滤器 9, 所述复合方 形体 225内部设有流体通道 221 , 在复合方形体 225各侧面具有相同偏心 距的位置上设有喷雾口形成偏心喷雾口 223 , 在复合方形体 225底面也设 有喷雾口， 形成普通喷雾口。 另外， 在入口管 226端部还固定有叶轮 4' , 以在流体通过时， 使叶轮 4'产生驱动喷头体 200旋转的力矩， 其原理与实 施例一目同。
上述实施例 2也可以做如下变形： 所述的复合方形体 225以图 1-1所 示的近似十字形的支臂代替， 形成座体的座腔内套装可转动的喷头体入口 管的喷射推动旋转式喷雾装置结构。
实施例 3: 如图 3、 图 3-1、 图 3-2及图 3-3所示。
本实施例所述的喷射推动旋转式喷雾装置也包括座体 310 及喷头体 320。 其中：
所述的座体 310内部中空， 其一端为入口 311 , 入口 311 内设有过滤 器 9, 入口 311外设有螺紋与输入流管 （图中未示出）相连接， 座体 310 的内孔 312上和出口处设上环面 315、 下环面 316。
所述的喷头体 320为空间母线回转形体， 其内空腔形成流体通道 321 , 该喷头体 320由分体设置的入口管 326、喷头体座 3201及喷头体主体 3202 组成， 该入口管 326可转动地套置在座体 310的内孔 312内做径向定位， 且入口管 326螺接在喷头体座 3201上方， 喷头体主体 3202则螺接在喷头 体座 3201下方。 喷头体 320入口管 326的进口端外周设有上圓台阶 327 , 露于座体 310内孔 312之外的喷头体座 3201顶缘形成下圓台阶 328, 该上 圓台阶 327和下圓台阶 328分别与座体 310内孔 312的上环面 315和下环 面 316相配合， 形成的两个配合面共同为喷头体 320做轴向定位。 在露于 座体 310内孔 312外的喷头体座 3201下圓台阶 328和座体 310下环面 316 之间形成间隙环缝， 该间隙环缝设计成环缝喷雾口 340, 形成转动配合面， 该间隙环缝上还可设放射状细沟 （图中未示出 )用以向外导流增加漏液喷 雾，少量流体通过间隙环缝或 /和放射状细沟参入喷雾。同样，在入口管 326 端部还固定有叶轮 4' , 以产生驱动喷头体 200旋转的力矩。
所述喷头体主体 3202外周设有多个带偏心楔面槽 3231和眼形孔 3232 的斜喷雾口 323 (如图 3-1 ), 该斜喷雾口 323的喷流中心线与喷头体 320 轴心具有偏心距 h, 从而构成另一种结构的偏心喷雾口， 因而各斜喷雾口 323的喷流反作用力的合力乘以 h就等于喷射驱动转矩， 这样即形成另一 种喷射推动旋转式喷雾装置。
所述的带偏心楔面槽 3231眼形孔 3232的斜喷雾口 323也可以为带偏 心楔面槽 3231和细缝 3232' 的斜喷雾口 323' (如图 3-2及图 3-3所示）。 由于上述斜喷雾口 323或 323' 在眼形孔 3232或细缝 3232' 的外周还 设置了向外扩开的偏心楔面槽 3231 ,水从较小的眼形孔 3232或细缝 3232' 喷出后，在迅速扩开的偏心楔面槽 3231内形成薄膜状，因此可喷出细水雾， 这样就构成了喷射推进式细水雾喷雾装置。
再者， 如图 5所示， 本实施例所述喷头体 320的底部中央还设有一个 无转矩普通喷雾口 322, 它由双级旋流芯供液， 所述的双级旋流芯由中央 旋流雾化芯 305及双旋流雾化芯座 306组成， 中央旋流雾化芯 305设于所 述喷头体 320流体通道 321内， 该中央旋流雾化芯 305固定在双旋流雾化 芯座 306上， 双旋流雾化芯座 306则固定在喷头体座 3201上，双旋流雾化 芯座 306的侧壁上开有切向槽 307 , 该中央旋流雾化芯 305的喷雾口与所 述喷雾口 322共同形成双喷雾口， 当两者同轴串联， 即一外一内时， 即构 成串级喷雾口； 由于上述形成的双喷雾口为无转矩设置， 因此形成普通的 喷雾口 322。
上述喷头体上的喷雾口或者偏心喷雾口可以由各种结构的雾化芯构 成， 雾化芯的具体结构可有多种， 本发明举例说明其中的几种雾化芯。
图 4是涡旋流斜喷雾口雾化芯的结构示意图。
在带外螺紋的雾化芯座 031内设旋流腔 030, 内置涡旋流芯 033 , 涡旋 流芯 033上设有旋流通道， 涡旋流芯 033为一整体分叶结构， 它的中央直 立平扁片的两侧分出互相反向倾斜的两叶导流片， 导流片的两片对立的半 圓廓密配在旋流腔孔内， 旋流腔的收缩锥孔连接与雾化芯腔中心线斜交的 喷雾口 003从而形成斜喷雾口 003。
图 4-1是旋流斜喷雾口雾化芯的结构示意图。 该雾化芯的芯座 011 内 腔孔中配装旋流套 012和喷雾口座 013 , 喷雾口座 013内设斜喷雾口 001 , 旋流套 012的顶壁封死， 内部形成单级旋流腔 015 , 环壁上设有 2~4只旋 流通道， 图中实施例中的旋流通道为切向槽 014, 旋流套 012 内孔与喷雾 口座 013的漏斗形孔入口紧密对接， 漏斗形孔连接斜喷雾口 001 , 喷雾口 座 013与芯座 011之间可以转动并设有密封 01 , 该雾化芯的孔腔输入孔 0108设于孔腔底部。 上述斜喷雾口雾化芯还包括雾化芯腔内设双级旋流芯并带有双喷雾口 的雾化芯， 所述内设各种雾化芯的雾化芯腔都连带斜喷雾口， 它们是与雾 化芯腔的收缩锥孔斜连接的喷雾口， 即雾化芯腔的收缩锥孔中心线与喷雾 口中心线斜交叉。
图 5是斜置旋流子雾化芯的结构示意图。 在带外螺紋的雾化芯座 021 内斜置带收缩喷雾口 002的圓柱形的旋流子孔， 圓柱形的旋流子 022置于 旋流子孔内， 旋流子 022圓柱形外周上均布两条螺紋槽旋流子孔及其喷雾 口， 旋流子 022圓柱形中心线与雾化芯座 021中心线斜交。
上述几种雾化芯的喷雾口均为斜喷雾口， 也可以是斜偏心喷雾口， 而 所述雾化芯的喷雾口也可以设置成非偏心的直喷雾口。 当将具有斜喷雾口 的雾化芯设置于喷头体上非偏心设置的雾化芯腔内时， 即可形成所述的偏 心喷雾口；而当具有直喷雾口的雾化芯置于喷头体的偏心雾化芯座腔内时， 同样可形成所述的偏心喷雾口， 偏心喷雾口是偏离喷头体中心的雾化芯腔 所连带的喷雾口， 而且该偏心喷雾口中心线与喷头体中心线不相交； 它包 括喷雾口与其雾化芯腔同心的喷雾口， 和喷雾口与其雾化芯腔不同心的喷 雾口。 也就是说， 雾化芯腔所连带的偏心喷雾口包括喷雾口与其雾化芯腔 同心的偏心喷雾口、 和与雾化芯腔不同心的斜喷雾口以及雾化芯斜置于雾 化芯腔座内形成的斜喷雾口。 另外， 带雾化芯的喷雾头内可设有过滤器。 的喷雾装置， 如图 6、 图 6-1及图 6-2所示。
所述的旋转喷雾装置主要包括座体 1及喷头体 2。 其中： 所述座体 1 内中空， 形成座腔， 座腔一端为入口 11与外部输入流管（图中未示出）相 连接， 另一端为出口腔 12, 该入口 11可设置一个过滤器 13。
所述喷头体 2为转子体， 其内设有流体通道 21 , 该流体通道 21的输 入端通过一连接组件与座体 1转动连接并且与座腔相通， 其输出端连接若 干喷雾嘴 22, 该喷头体 2和其设有的喷雾嘴大至形成转动平衡体。
所述的连接组件可为旋转接头 3 , 该旋转接头 3包括外接头 31、 轴承 32、 轴承压盖 33、 弹簧卡 34及若干密封 35; 该外接头 31下方与喷头体 2 连接， 其上方套于做为内接头的座体 1的出口腔腔壁 37上， 所述轴承 32 设于出口腔腔壁 37和外接头 31之间； 弹簧卡 34则卡于轴承 32上用以固 定轴承 32, 所述轴承压盖 33盖于外接头 31上； 所述密封 35可为普通 0 形圈， 也可由沟槽里边的 0形圈和外侧的耐磨低磨擦阻力塑料环构成组合 密封。 所述外接头 31与喷头体 2之间， 及所述出口腔腔壁 37与轴承压盖 33之间均可以螺接方式连接， 从而使该旋转接头 3 的内接头与外接头 31 间可快速转动而不泄露内部的有压流体。 需要说明的是， 本发明所述旋转 接头的内、 外接头， 并非指空间上的内外， 而是把与座体 1连接或直接取 代座体 1的接头都定义为内接头，把与喷头体 2连接的接头定义为外接头。
所述自驱动旋转喷雾装置还设有在接受流体流动推力时， 产生带动喷 头体 2旋转扭矩的驱动机构。 该驱动机构可为被击式叶轮， 该被击式叶轮 设置于座体 1与喷头体 2之间的、 具有压力的流体腔室内； 该被击式叶轮 与喷头体 2—体转动， 且转动方向与上述连接螺紋的旋紧方向一致。 如图 6-1 所示， 本实施例中， 所述的被击式叶轮为带有倾斜叶片的轴流式或半 轴流式浆形叶轮 4。 该浆形叶轮 4固定于旋转接头 3的外接头 31内， 其可 设置 1~2个， 每个浆形叶轮 4可有 3~6片浆叶； 而该浆形叶轮 4也可固定 在喷头体 2的入口，或者在外接头 31和喷头体 2入口各设置一个。 当座体 1的出口腔 12内的轴向或斜轴向水流冲击浆形叶轮 4时， 水流作用力可对 浆形叶轮 4产生旋转分力矩， 使浆形叶轮 4旋转， 进而带动喷头体 2向 D 方向旋转转动， 形成反击式转动驱动机构。
所述驱动机构还可为设置于喷头体 2上的至少两个偏心喷雾嘴 23 ,如 图 6-2所示， 各偏心喷雾嘴 23围绕喷头体 2轴线呈空间旋转对称分布， 且 偏心喷雾嘴 23的喷流中心线在垂直于喷头体轴线的平面内投影与喷头体 2 的轴心设有偏心距 h, 当偏心喷雾嘴 23喷射流体时， 流体喷射的反作用力 对喷头体 2形成转矩， 推动喷头体 2旋转， 并带动喷头体 2上的普通无转 矩喷雾嘴 22及偏心喷雾嘴 23—起转动， 从而形成喷射推进式转动驱动机 构。上述偏心喷雾嘴 23与上述浆形叶轮 4一起，构成了反击式与喷射推进 式联合驱动的转动驱动机构。 上述驱动机构中偏心喷雾嘴的喷流方向与叶 轮带动喷头体 2的转动方向相反， 优选的技术方案是， 喷头体 2的旋转方 向与所有连接螺紋的旋紧方向一致。 具体而言， 继续配合图 6-2所示， 本实施例所述的喷头体 2为十字形 体 24, 十字形体 24内也设有十字形流体通道 21 , 在喷头体 2的每个十字 臂的逆旋转方向均设有一个偏心喷雾嘴 23 , 每个偏心喷雾嘴 23均与流体 通道 21呈一定角度相通。另外，该喷头体 2的十字臂外端还可设有普通的 无转矩喷雾嘴 22。

所述的驱动机构还包括带有倾斜叶片的浆形叶轮。
本实施例与实施例 4的不同之处在于： 所述的浆形叶轮为具有倾斜片 形浆叶的浆形叶轮 4' , 该片形浆叶的浆形叶轮 4' 为片状材料冲压后再将 各叶片弯折成一角度而制成， 也可为压铸件。 此外， 本实施例所述的连接 组件包括入口管 5, 该入口管 5底部与喷头体 2连接 (可以螺紋方式连接， 此处入口管 5与实施例 1中的入口管具有基本相同的功能），其顶端固定所 述的浆形叶轮 4' , 而该入口管 5轴套于座体 1下方的出口腔 12内， 从而 形成滑动旋转轴承式连接。 为减少旋转滑动的摩擦力， 所述入口管 5与轴 孔 12之间可设有空槽 14, 该空槽 14处也可设置轴孔密封。 另外， 还可以 设引流孔 244和导流槽 243 , 在座体 1和喷头体 2之间的配合面设计成环 缝喷雾口。 其工作原理与实施例一的环缝喷雾口相同。

本实施例的喷头体 2a外壁开设若干大通孔 25a、 25b, 该大通孔 25a、 25b 内可用来嵌固或螺固各种独立结构的雾化芯喷雾嘴， 以形成具有特殊 喷洒效果的喷雾嘴 22a。 例如： 本实施例在四周位置的大通孔 25a内可嵌 固细水雾雾化芯喷雾嘴 8a; 在底部的大通孔 25b内嵌固旋流涡旋流双喷口 雾化芯喷雾嘴 8b。 所述的大通孔 25a、 25b 内也可以嵌固其它形式的雾化 芯， 如泡沫雾化芯、 互击孔气水雾雾化芯等等， 也可以嵌固其它类喷雾嘴， 如釆用其它如泡沫、 水雾等喷雾嘴。 在大通孔内设有喷雾嘴也可是具有偏 心距的喷射推进式喷雾嘴，形成反击式和喷射推进式叠加的旋转喷雾装置。 同样， 也可以在喷头体 2a设导流槽， 将喷头体 2a与座体 1之间的配合面 设计成环缝喷雾口。
实施例 7: 为本发明冲击式转动驱动机构配有多种喷雾头喷雾装置的 结构， 其结构示意图如图 9、 图 9-1、 图 9-2及图 9-3。
所述的自驱动旋转喷雾装置主要包括座体 1、 喷头体、 连接组件及驱 动机构。 所述的座体 1也设有入口 11及出口腔 12, 该入口 11通过一个常 闭阀 9与供水管道相连接， 常闭阀 9具有三通管， 该三通管的上方入口设 置一个过滤器 13 ,其旁侧口设置有一热敏机构 91 ,常闭阀 9的出口经座体 1 下方连接连接组件， 该连接组件为旋转接头 3 (其结构与上述实施例 4 相同， 不再描述）， 该旋转接头 3的外接头 31下方与喷头体连接， 所述座 体 1与喷头体之间的外接头 31的压力腔室内设有的被击式叶轮，该叶轮可 为具有接受旋流冲击的斗形叶片的叶轮 6 (如图 9-1 ), 或为具有弧板形叶 片的叶轮 6' (如图 9-2 ), 还可为具有直板形叶片的叶轮 6 " (如图 9-3 ), 该叶轮 6通过轮支架 61固定于外接头 31内， 且与其叶片对应， 并在叶轮 6外周的座体 1腔内或外接头 31孔腔内固定一圈旋流喷口 62,该旋流喷口 62可设置在一固定座 63上。 当叶轮 6受到旋流喷口 62的旋流冲击力时， 就带动外接头 31及喷头体一体转动，从而构成冲击式转动驱动机构。 同样 优选的技术方案是， 喷头体的旋转方向与各连接螺紋的旋紧方向一致。
本实施例在旋转接头 3的外接头 31下方螺接的喷雾头可以是细水雾喷 雾头 7c等各类喷头，从而形成各种特定的闭式旋转喷雾装置； 如闭式泡沫 或泡沫喷雾旋喷头、 闭式细水雾或气水雾旋喷头、 闭式水喷雾旋喷头、 闭 式油雾旋转喷头等喷雾装置； 本实施例如在旋转接头 3入口取消常闭阀 9 则上述各闭式旋转喷雾装置就变成了相应的开式旋转喷雾装置； 如开式泡 沫或泡沫喷雾旋喷雾装置、 开式细水雾或气水雾旋喷雾装置、 开式水喷雾 或大水滴喷淋旋喷雾装置、 开式油雾旋转喷头等喷洒喷雾装置。 该喷头体 和其设有的喷雾嘴大至为转动平衡体。
实施例 8: 为本发明冲击式与喷射推进式联合作用并叠加多个喷头体 的旋转喷雾装置， 如图 10及图 10-1所示。
本实施例与实施例 4基本相同， 相同部分不再重述。 而本实施例所不 同的是： 在上述实施例 4的旋转接头 3下方垂直叠加两层十字形体的喷头 体 2, 且两层喷头体 2的十字形体交错设置（如图 10-1 ), 从而构成具有冲 击式与多层喷射推进式组合驱动结构的喷雾装置。 上述两层喷头体 2间可 以螺紋连接并且销定位， 而下层的喷头体 2的底面也可设有若干无转矩喷 雾嘴 22。 本实施例下层的喷头体 2 也可为具有各种特殊喷雾效果的喷头 体，。 本实施例所述旋转接头 3内的轴承为双列滚珠轴承。
实施例 9: 为本发明另一种带冲击式转动驱动机构的喷雾装置结构示 意图， 如图 11所示。
本实施例所述的自驱动旋转喷雾装置同样是包括座体 1、 喷头体 2b、 连接组件及驱动机构。
所述座体 1同样设有入口 11及出口腔 12, 该入口 11设置一个过滤器
13。
所述喷头体 2b为回转体， 其外周设有多个眼形孔喷雾嘴 26b, 由于该 眼形孔喷雾嘴 26b在小喷孔的外周还设置了向外扩开的大斜孔， 水从小喷 口喷出后， 在迅速扩开的大斜孔内形成薄膜状， 因此可喷出细水雾。
所述的连接组件包括了轴承 32、 轴承压盖 33、 弹簧卡 34及密封 35 , 该轴承 32直接设置于喷头体 2b与座体 1的出口腔 12外壁之间，设于座体 1上的轴承压盖 33使轴承 32定位且盖于喷头体 2b上。
所述的驱动机构为斗形叶片或板形叶片叶轮 6、 6' 、 6 " , 其通过一轮 支架 61及旋流座 27b固定于喷头体 2b内， 在叶轮 6、 6' 、 6 " 的外周设置 有一固定座 63 , 固定座 63上对应叶轮设有一圈旋流喷口 62, 该叶轮形成 此外， 所述轮支架 61上开有斜槽或旋流槽，所述旋流座 27b的外侧壁 开有旋流槽 28b, 其内侧壁设有锥形喷孔， 该旋流座 27b固定在喷头体 2b 上， 喷头体 2b下方中央设有一个喷雾嘴 22b, 这样即形成一种具有双旋流 并联喷雾嘴的雾化芯结构。 可以理解， 本例提供的喷雾装置可以与实施例 7的常闭阀 9的出口相连， 形成常闭的喷雾装置； 也可以与实施例 7中外 接头 31下方螺接的喷雾头相连， 形成多级旋转喷雾装置。
需要说明的是， 本发明中的反击式驱动机构釆用的叶轮和冲击式驱动 机构所釆用的叶轮统称为被击式叶轮。
本发明上述各实施例中旋转喷雾装置的喷头体 2、 2a或细水雾喷头 7c 上可以设置各种能喷细雾的雾化芯喷雾嘴， 这样就形成了 "自驱动细雾化 旋转喷雾装置"， 如果使用的是水则形成 "自驱动细水雾旋转喷雾装置"。
例如图 8的旋流涡旋流双喷口雾化芯喷雾嘴 8b、 图 11中下方中央的 喷雾嘴 22b及其上方结构、 图 11中的眼形孔喷雾嘴 26b, 都是雾化芯喷雾 嘴。
上述的雾化芯喷雾嘴也可以偏心设置， 形成具有偏心距的雾化芯喷雾 嘴， 该喷雾嘴产生的喷射转矩， 与反击式叶轮产生的转矩联合驱动细雾化 喷雾装置， 形成旋转喷雾。
上述自驱动旋转细雾化喷雾装置的喷头体上还可设置各种结构的细雾 雾化芯喷雾嘴， 作为举例， 本发明再着重给出以下 2种细雾化芯喷雾嘴：
1 )双旋流雾化芯喷雾嘴， 包括并联及串联两种， 下面以串联为例进行 说明：

2 ) 一种带撞击孔喷雾嘴的转子雾化芯， 结构示意图参见图 12-2。 该雾化芯喷雾嘴设有一雾化芯座 0125 , 其内有 3~6 个均布斜交的孔
0121 , 每个孔 0121的出口小喷孔 0123轴线对称相交， 孔 0121 内置具有 1~3条螺旋导流槽 0122或多条斜细槽 0122' 的可转动小柱 0124, 喷头孔 腔的输入孔 0126与孔 0121相通， 水流从螺旋导流槽 0122或 0122' 内流 入， 带动小柱 0124旋转， 形成薄水膜， 多股水膜射流撞击后二次雾化， 从 而构成旋流转子撞击孔雾化芯。
实施例 10: 为本发明冲击式和反击式联合旋转驱动长管喷雾枪式喷雾 装置， 参见图 13所示。 本实施例与图 9所示的实施例 7的喷雾装置相近似， 因而图 13与图 9 中标号相同部分不再描述。 本实施例所不同的是： （1 )本实施例去掉了图 9中的常闭阀 9; ( 2 )本实施例也不用图 9中的各类喷头 7c, 而用液气引 射式文丘里雾化喷雾枪 9G、长硬管喷雾枪 9H、长软管喷雾枪 91三种长管 形喷雾枪取代； （3 )本实施例用了两个滚动轴承 32; ( 4 )本实施例的旋转 驱动机构除釆用如图 9所示那样的冲击式叶轮 6外， 还增加了如图 6所釆 用的反击式浆形叶轮 4, 两种旋转驱动机构并用， 可增加旋转动力。 本发 明中的反击式驱动机构釆用的叶轮和冲击式驱动机构所釆用的叶轮统称为 被击式叶轮。
本实施例的旋转喷雾装置的输入流体可为水、 油、 或者其它类液体，
Figure imgf000025_0001
雾化喷雾枪 9G、长硬 管喷雾枪 9H、长软管喷雾枪 91, 它们所配喷雾嘴可根据喷流介质及喷流细 化度而选择。 长软管喷雾枪 91仅适用于某些需弯曲置入的特殊场合。 液气 引射式文丘里雾化喷雾枪 9G可用于燃烧喷雾， 它由雾化喷射嘴 gl、 吸气 孔 g2、 引气室 g3参气套 g4、 喉管 g5、 扩散喷雾管 g6组成。 扩散喷雾管 g6出口处还可加设扩散叶 g7等。 而雾化喷射嘴 gl还可选用图 12-2所示 的那类多孔喷雾嘴。
在需要精细喷雾时， 本实施例的入口 11可选用过滤器。
本发明所述的自驱动旋转喷雾装置可以用于灭火及其它喷雾， 可单独 使用也可群组使用。 单独使用是将一个自驱动旋转喷雾装置做为单个灭火 喷头或喷雾枪用。 群组使用是将多个自驱动旋转喷雾装置安装在自动喷洒 水、 水喷雾、 细水雾、 泡沫喷雾等灭火系统的各管路终端做开式或闭式旋 喷头使用， 也可将该自驱动旋转喷雾装置安装在喷雾除尘、 喷雾干燥、 喷 雾喷灌等管路终端做群组喷雾用。
