Description
一种热气溶胶灭火装置用双向喷发点火具 技术领域 Two-way eruption ignition device for hot aerosol fire extinguishing device
本发明属于气体灭火技术领域， 涉及一种双向喷发点火具， 尤其涉及一 种热气溶胶灭火装置用双向喷发点火具。 背景技术 The invention belongs to the technical field of gas fire extinguishing, and relates to a two-way erupting ignition device, in particular to a two-way erupting ignition device for a hot aerosol fire extinguishing device. Background technique
在气溶胶灭火装置中，点火具的设计和可靠性对于整个装置功能发挥的 好坏至关重要， 其中必须考虑点火包装药的品种、 用量、 包装药的密封性、 防潮性， 抗震性、 以及启爆药的装配、 压药工艺和点火性能的改进， 同时还 必须防止内部装药的振动。 尤其是对于双向喷放气溶胶的装置， 还必须考虑 双向点火的同步一致性。 In aerosol fire extinguishing devices, the design and reliability of the ignition device are critical to the function of the entire device. The type and amount of the ignition packaging drug, the sealing property of the packaging drug, the moisture resistance, the shock resistance, and The assembly of the primer, the pressure-pressing process, and the improvement of the ignition performance must also prevent the vibration of the internal charge. Especially for devices that spray aerosols in both directions, the synchronization of the two-way ignition must also be considered.
在本发明以前的现有技术中， JP56165832 ( A ) 专利文件中公开了一种 双向压电点火具，该点火具用于装置中，目的是降低电点火具点火的失败率； 其结构特征是： 内部用一个有两个操作件的凸轮和一个操作杆， 使一次点火 操作时驱动点火锤两次， 实现两次放电点火。 这种点火具只是部分减少了点 火的失败率， 没有提到安全性和同步性的问题， 且结构既笨重又复杂。 目前 国内市场上的双向横喷气溶胶灭火装置，其点火元件还是采用自封袋装点火 药， 用透明胶带包扎的点火药包。 这种药包启动方式存在点火包装药没有定 量、 密封性不佳、 自封袋在高温试验中易破损、 启动点火不同步、 点火效果 相差很大等缺陷。 此外， 在运输过程中， 点火药包可能由于颠簸， 脱离中心 位置， 或者药包破散， 这样就不能很好地启动装置， 会造成发生火灾时， 不 能及时灭火的现象。 根据文献检索的结果， 所得到的 37件专利中所涉及的 点火具主要用于安全气嚢 （如 CN86203126; CN200520011152.8; 8610332;
200610022391.2 ) ； 火箭发动机 （如 CN 03218960.5 ; 200320103882.1 ; 200620147019.X )等; 点火方式有热锂电点火（ CN96236373.1 )； 沖击波式 点火具（CN00261694.7 )等， 均不涉及气溶胶灭火装置点火具的药剂和结构 设计。 发明内容 In the prior art of the present invention, JP56165832 (A) discloses a bidirectional piezoelectric ignition device for use in a device for the purpose of reducing the failure rate of ignition of an electric ignition device; : The inside uses a cam with two operating members and an operating lever to drive the hammer twice during one ignition operation to achieve two discharge ignitions. This type of ignition device only partially reduces the failure rate of ignition, does not mention the problems of safety and synchronism, and the structure is cumbersome and complicated. At present, the two-way cross-jet aerosol fire extinguishing device on the domestic market, the ignition element is still a self-sealing bagged ignition powder, and an ignition powder bag wrapped with a transparent tape. The starting method of the drug pack has the defects that the ignition packaging drug is not quantitative, the sealing property is not good, the self-sealing bag is easily broken in the high temperature test, the ignition is not synchronized, and the ignition effect is greatly different. In addition, during transportation, the ignition pack may be out of the center due to bumps, or the medicine pack may be broken, so that the device cannot be started well, and the fire cannot be extinguished in time. According to the results of the literature search, the ignition tools involved in the 37 patents obtained are mainly used for safety gas (such as CN86203126; CN200520011152.8; 8610332; 200610022391.2); rocket engine (such as CN 03218960.5; 200320103882.1; 200620147019.X); ignition mode with hot lithium ignition (CN96236373.1); shock wave ignition device (CN00261694.7), etc., do not involve aerosol fire extinguishing device ignition device Pharmacy and structure design.
