A segmented sealing high pressure sealing member

Abstract

The invention belongs to the field of applications of initiating explosive devices, provides a segmented sealing high pressure-bearing sealing part, and solves the problem that the impact force generated by output detonation damages the structure and sealing property of a product. By taking a conventional 12Cr18Ni9 as a sealing shell material, iron sealing glass as a sealing glass material and 4J50 as a sealing contact pin material, the sealing structure is finished by weakening the impact waves through sealing gaps by way of reserving gaps in a segmented manner for the first time, so that the demand on pressure-bearing and sealing properties on the ignited product is guaranteed. The sealing and pressure-bearing properties of the product are improved by innovating the sealing method and changing the sealing structure, and the segmented sealing high pressure-bearing sealing part has the advantages of being novel in design, simple in structure and easy to implement, and the inherent safe reliability of the product is not affected and the like.

Description

technical field [0001] The invention belongs to the field of pyrotechnics, and relates to an electric pyrotechnics for ammunition weapons, in particular to an integrally sealed electric detonator. Background technique [0002] With the needs of my country's national defense security and the development of China's manned spaceflight project, the application field of electro-technical products is also expanding. The role of electro-technical products for aerospace products and missile weapons is like the heart of the human body. play a vital role. The sealing and pressure bearing of electrical explosive devices have always been two crucial technical indicators. [0003] The structure of the overall sealed electric detonator is mainly composed of sealing parts, ceramic sheets, electric bridges, charges, cover sheets and other parts. The sealing component is the structural carrier of the electric detonator. The traditional integral sealing component structure includes It is an ...

Problems solved by technology

If the sealing performance is poor, it may lead to problems such as propellant leakage and equipment pollution, and in severe cases, it may lead to mission failure; if the product’s pressure bearing capacity is too low, it will lead to structural damage in complex thermal and mechanical working environments

[0004] When the traditional integral seal detonator outputs detonation, the shock wave generated will shatter the sealing glass and cause leakage. The traditional solution is to increase the partition, but the increase of the partition will increase the size of the product. The increase will affect the system space layout and overall assembly, and it will also increase the weight of the product, which in turn will affect the payload of the system
