图 2为本发明阻火装置结构示意图。
图中： 1、药柱 2、点火药包 3、冷却层 4、阻火装置 41、阻火挡板 42、 引流壁 43、 喇叭口 44、 过烟孔 5、 隔热层 6、 顶盖 具体实施方式： 下面结合说明书附图对本发明做进一歩的描述。
实施例 1
本发明的阻火方法由以下的歩骤实现：
1 ) 在灭火气溶胶的喷射方向上设置阻火装置 4， 灭火装置中的烟火药剂引 燃后经过化学冷却剂的冷却后使其燃烧的火焰的热量大幅减小， 随后， 到达阻 火装置 4的阻火挡板 41， 通过阻火挡板 41将烟火药剂的火焰一部分阻挡， 剩余 部分火焰和气溶胶烟雾被阻火装置 4的引流壁 42引流向其边缘分散；
2)分散在阻火装置 4边缘的火焰和气溶胶烟雾沿着灭火装置筒壁向灭火装 置顶盖 6扩散， 并被顶盖 6阻挡形成涡流， 使火焰动能产生衰减；
3 )形成涡流的气溶胶烟雾从喇叭口 43上的过烟孔 44进入阻火装置 4和顶 盖之间的空腔， 当空腔中的气压超过顶盖的喷口处的密封塞的承受能力时， 就 会将密封塞冲出， 从顶盖 6的喷口喷出来， 进行灭火。
参见图 1和图 2， 本实施例的阻火装置 4由阻火挡板 41、 引流壁 42和喇叭 口 43联接构成。
具体是： 阻火挡板 41采用耐高温、 耐腐蚀的钢板制成， 其直径小于灭火装 置的药筒内径， 在阻火挡板 41的外边沿与引流壁 42联接， 引流壁 42向外倾斜 设置， 与阻火挡板 41之间形成一定的角度， 引流壁 42的外直径大于阻火挡板 41的直径小于药筒的内径， 即引流壁 42的最大直径小于药筒的内径， 使得引流 壁 42与药筒壁之间有一定的间隙， 火焰和烟雾会随着间隙进入喇叭口 43与灭 火装置顶盖之间的空腔， 被顶盖阻挡后形成涡流， 喇叭口 43 倒扣在引流壁 42 的上方， 与引流壁 42之间形成一个空腔， 在喇叭口 43的边沿处设置有缺口，
形成本实施例的过烟孔 44。
为了便于安装， 本实施例的阻火挡板 41、 引流壁 42和喇叭口 43为一体式 结构。
使用时， 本实施例的阻火装置 4是设置在灭火装置的药筒内， 临近喷口的 位置， 即在灭火装置的药筒内依次设置烟火药剂药柱 1、 点火药包 2、 冷却层 3 以及阻火装置 4，在药柱 1和点火药包 2的外部与药筒内壁之间还设置有隔热层 5， 在药筒的顶端设置顶盖 6， 当启动灭火装置的启动控制器， 点燃点火药包 2， 随即引燃烟火药剂药柱 1， 即烟火药剂引燃后产生大量的气溶胶烟雾和火焰， 穿 过冷却层 3， 经过冷却层 3冷却后火焰的热量大幅减小， 再经过阻火装置 4的阻 挡， 火焰的热量损耗严重， 无法从顶盖喷出， 但是气溶胶烟雾会随着孔隙过流， 在阻火装置 4的喇叭口 43积聚， 从而从顶盖 6的喷口喷放， 实现灭火。
实施例 2
本实施例的阻火挡板 41是中间突起的圆弧形界面结构， 与引流壁 42联接 形成一个圆锥体结构， 采用镀锌钢材质制成， 其他的部件及其连接关系同实施 例 1相同。
