Problems solved by technology

However, if there are cracks in the pyrotechnic powder column during production or transportation, it may cause deflagration of the powder column, and the sudden rise of UHV gas is too late to release. Once the pressure exceeds the pressure limit of the device itself, an explosion will occur, thereby triggering Serious damage to the operator and the surrounding machinery and equipment; in addition, the operating environment of the device may have various harsh conditions such as high-frequency vibration, high humidity, and high salt spray corrosion. If the structural stability and protection of the device itself cannot meet the requirements, May cause device failure
[0003] However, most of the current aerosol fire extinguishing devices do not have corresponding measures or means to solve the above problems. Therefore, the structure of the existing aerosol fire extinguishing devices must be improved in order to effectively avoid personnel injuries caused by deflagration and device failure during use.

Abstract

The invention provides an aerosol propellant grain ignition device and a production method. The ignition device comprises a propellant cylinder, and the propellant cylinder is a container for fixationand reaction; an opening is formed in the side wall of the propellant cylinder; a dispensing jig is arranged on the opening in a positioned mode; and a grain is arranged at the bottom of the propellant cylinder through axial positioning structures and a radial positioning structure in a positioned mode. The aerosol propellant grain ignition device and the production method aim to overcome the technological defects of an existing aerosol fire extinguishing device propellant grain in the production process and have the advantages that the aerosol propellant grain can be effectively ignited, meanwhile, the combustion of the aerosol propellant grain can be effectively improved, and the overall structural stability can be ensured.

Description

technical field [0001] The invention relates to a gas fire extinguishing technology in the field of fire safety, in particular to a production method capable of effectively igniting an aerosol generating agent powder column while effectively improving the combustion and overall structural stability of the aerosol generating agent powder column. Background technique [0002] At present, the existing fire extinguishers use the pyrotechnic agent with a faster burning rate as the main agent, which is made into a powder column by molding and fixed in the generator cartridge. When the product works normally, the powder column burns in an orderly and stratified manner to produce a stable aerosol smoke. However, if there are cracks in the pyrotechnic powder column during production or transportation, it may cause deflagration of the powder column, and the sudden rise of UHV gas is too late to release. Once the pressure exceeds the pressure limit of the device itself, an explosion wi...
