Detonating tube assembly, detonating medicament thereof and manufacturing method of detonating medicament

Abstract

The invention relates to a detonating tube assembly, a detonating medicament thereof and a manufacturing method of the detonating medicament. The detonating tube assembly comprises a detonating tube made of engineering plastic, a cork, the detonating medicament and a temperature sensing line, wherein the detonating medicament is located in the cavity of the detonating tube; the cork seals the opening of the cavity of the detonating tube; one end of the temperature sensing line is located in the detonating tube and inserted into the detonating medicament, and the other end of the temperature sensing line is penetrated out from a through hole of the cork; the compositions of the detonating medicament comprise potassium nitrate and / or potassium perchlorate, an organic substance which is usedas a combustion aid and a viscosity, and an additive for increasing the reaction speed; and the additive comprises potassium tetraborate and / or potassium iodide. The detonating tube assembly, the detonating medicament thereof and the manufacturing method of the detonating medicament have the advantage of high safety.

Description

[0001] 【Technical field】 [0002] The present invention relates to fire-fighting equipment, in particular to equipment suitable for fire prevention, suppression or extinguishment, such as an automatic fire extinguishing device, and in particular to a detonator assembly used on an automatic fire extinguisher. The present invention also relates to a detonator A detonating charge within an assembly and a method of making the detonating charge. [0003] 【Background technique】 [0004] With the development of the economy and the progress of the society, more and more fire extinguishers (also known as fire extinguishing devices) have entered each of our families, kitchens, indoors and outdoors, and can be used from any angle; fire safety has become an inevitable social consensus. All kinds of fire-fighting equipment are more and more developed in the direction of energy saving, environmental protection, convenient use, safety and high efficiency. Fire extinguishers have become an im...

AI Technical Summary

Problems solved by technology

see Figure 5 and Image 6 , The detonating tube assembly 10' is used in the automatic fire extinguishing device. The detonating tube assembly 10' is set in the second cavity 99' of the bottle core (also known as the inner tube) 90' of the automatic fire extinguishing device, and the bottle core 90' ​​is set in the automatic fire extinguishing device. In the first cavity 29' of the bottle body 20' of the fire extinguishing device, the bottle cap 30' seals the opening of the second cavity 99' of the bottle core 90', and the temperature sense from the through hole of the bottle stopper 12' The other end of the line 14' passes through the opening of the second cavity 99' of the bottle core 90' ​​and the bottle cap 30' respectively and is located on the outer surface of the bottle body 20', and the fire extinguishing agent is arranged in the first container of the bottle body 20'. cavity 29'; when a fire occurs, the temperature-sensing line 14' contacts the open flame to activate the detonating agent 13' in the detonating tube 11', causing the bottle body 10' to explode and disperse into multiple fragments, and the fire extinguishing agent in the bottle body 10' The agent is sprayed out in mist, so as to achieve the purpose of extinguishing the fire; because the above-mentioned detonating agent 13' is composed of potassium nitrate, sulfur, charcoal and metal powder, the detonating agent 13' is powdery, and because the detonating agent 13' contains sulfur and metal powder, The entire detonating agent is more sensitive and less safe; moreover, during storage, transportation and / or use, the temperature-sensing line 14' is artificially pulled or hooked by an object. Since the detonating agent 13' is in powder form, it is located in the detonating tube 11' The temperature-sensing line 14' in the cavity 111' has been coated with powder, and when the temperature-sensing line 14' is easily pulled out, it will be squeezed and rubbed against the bottle stopper 12', which will cause the entire detonating tube assembly 10' to be released in the future. Mistakenly activated when a fire hazard is foreseen, which leads to the early start of the automatic fire extinguishing device, or after the temperature sensing line 14' is pulled out, the entire detonator assembly 10' fails when there is a fire hazard, resulting in the failure of the automatic fire extinguishing device. for fire fighting purposes
