灭火弹是一种消防灭火的消耗性器材，一般填充干粉以及爆炸抛散干粉的装填药。依靠爆炸纷飞的干粉隔绝火源与空气实现灭火目的。小型的有橘子大小，直接扔到火场就可以爆炸灭火，大一点的像手榴弹，拉燃使用，还有更大的，可以用飞机投掷。
也有固定在建筑或车船飞机要害位置的灭火弹，用于防范突发火灾。而基于灭火救灾的危险性，还发展了利用高压空气作为动力的气动远程灭火系统，该系统由灭火炮和和灭火弹组成；通常，灭火炮采用气源发射无任何火工品，主要使用瞬间释放压缩气体的冲击将灭火弹推送至目标位置，灭火弹碎裂后实现灭火剂的远距离释放。

如图3和图4所示，盖体21设于围裙22顶面位置，盖体21形状为圆形平面，并与连接环23相对固定，盖体21的厚度大于围裙22其他位置的厚度。围裙22内设有若干个环绕围裙22中心线等距分布的加强筋24，加强筋24的一侧面连接于围裙22的内壁上，另一侧面贴合固定在连接环23的外壁上。
如图3和图4所示，弹体1开口的一侧凸出设置形成环状凸台13，环状凸台13呈平滑圆台状，其形状与围裙22内部形状贴合，环状凸台13与弹体1末端连接处形成环状的连接台14，安装时连接台14与围裙22底面贴合设置。
如图3和图4所示，灌装口11与承压盖2之间还设有密封件，用于在二者连接时将之密封连接。本实施例中，密封件即为螺纹31，螺纹31不仅起到连接灌装口11与承压盖2的作用，更在二者之间形成密封，防止弹体1内的液体灭火剂泄漏流出。
连接时，只需将承压盖2上的连接环23对准灌装口11套设其上，并将整个承压盖2拧接在灌装口11上，利用螺纹31进行密封,此时承压盖2能够包围、密封灌装口11。
在使用过程中，承压盖2在受到冲击时能够正面承受压缩气体产生的推力，盖体21内设置加强筋24，能够利用连接环23与加强筋24，配合设置的环状凸台13贴合围裙22，连接台14贴合围裙22底面，将受到的冲击作用力均匀分散在环形凸台、连接台以及弹体的侧壁上，避免弹体1受力不均造成的变形甚至破损，保证弹体1发射过程中的完整性。
而为了提升灭火弹的弹体1与承压盖2之间的连接密封性和牢固性，可以增设密封件，密封件除螺纹31外，还包括密封垫32，密封垫32嵌设于连接环23内，且通过高频焊接的方式固定在灌装口11的顶面上。而在需要时，弹体1上还可以设置侧加强筋15，侧加强筋15环绕弹体1中轴线等距分布若干个，用于增加弹体1整体强度。
灭火弹落地后，其中装载的灭火剂能够配合撞击作用，找到弹体1上强度较弱的位置，保证灭火弹在指定位置炸裂。设置加强筋15对于灭火弹的碎裂无碍，还能够进一步增强弹体1的强度，分散发射过程中受到的冲击，保护弹体1在发射时的完整性。
本实用新型整体结构简单，仅分为弹体1与承压盖2两部分，弹体1的设计能够提供较大的灭火剂装载量，承压盖2则能够实现保护弹体1与承受发射瞬间压力的作用，在保证安装密封性和强度的情况下，减少了灭火弹整体的重量和结构，提升了灭火弹的推送距离，降低了灭火弹的生产成本和使用成本，便利了灭火弹的推广使用。
除上述实施例外，本实用新型还可以有其他实施方式。凡采用等同替换或等效变换形成的技术方案，均落在本实用新型要求的保护范围。
