一种爆炸二极管机理研究及熄爆通道尺寸对其性能的影响

依据爆炸逻辑元件的工作原理设计了一种爆炸二极管。实验研究了元件内部结构，确定了关键参数为熄爆通道的长度、隔爆序列。隔爆序列内采用激发装置、一次PETN装药、两次PETN装药不同密度分层装药序列。在A、B端连接导爆索，改变熄爆通道尺寸, 确定分层装药参数，进行传爆可靠性、隔爆安全性实验。结果表明:爆轰信号由A端正向输入时，可以顺利通过10~35 mm的熄爆通道并且可靠引爆B端导爆索，满足可靠性功能；爆轰信号由B端反向输入，在熄爆通道长度为15~35 mm时，爆轰信号在通过隔爆序列、熄爆通道时被可靠阻断无法引爆A端导爆索，满足隔爆安全性功能。最终元件选取长度为15~35 mm的熄爆通道, 确定不同密度分层装药参数作为设计标准。应用于爆破网络设计中，使爆轰波信号在网络中单向传播，增加了网络的安全性。

Mechanism of an explosion diode and effects of its extinction channel size on its properties

An explosive diode was designed according to the principle of explosive logic components.This paper studied thorough experiment of the internal structure of the components to identify the length of extinction channel and flame-proof structure as key parameters.The flame-proof structure adopted the layered charges of different density including an excitation device,1st charge of PETN,2nd charge of PETN.Connecting the A-end and B-end to the detonating cord,changing the size of the extinction channel,ensuring the parameter of the layered charge to conduct the experiment of detonation reliability and explosion-proof safety,the results show that the detonation signal can detonate the B-end detonating cord,satisfying the reliability function while passing through the extinction channel of 10 mm to 35 mm by inputting from the A-end.While the detonation signal input from the B-end was not able to detonate the A-end detonating cord to meet the flame-proof function across the flameproof structure and extinction channel when the length of the extinction channel is 15 to 35 mm.The result indicates the length of the extinction channel amongst 15 mm to 35 mm and the layered charge of different densities can be selected as the design standard of the blasting network to make the denotation signals transmit in one direction in the network,thus increasing the security of the network.
