The invention discloses a dry powder fire extinguishing bomb ignition delay detonation device and a dry powder fire extinguishing bomb. The dry powder fire extinguishing bomb includes an ignition delay detonation device, a fire extinguishing bomb shell, a dry powder fire extinguishing agent, a safety paper seal and a pull ring, an ignition delay detonation device and The dry powder fire extinguishing agent is placed in the shell of the fire extinguishing bomb, and the mouth of the shell is provided with a pull ring, and the safety paper seals the opening of the shell of the fire extinguishing shell; the ignition delay detonation device includes a fire spring, an outer shell, a friction cap, an inner shell, Fuses, Exploders, Detonators and Ribs. The pull spring and friction cap are selected as standard products; the material cost is reduced, the delay accuracy and fire transmission reliability are improved by improving the fuse for the grenade; anti-sprinkling, anti-fire and moisture-proof design are carried out; The exhaust channel design adopts a three-way redundant design, and the overheated parts such as the outer shell and inner shell are made of flame-retardant plastics with good heat resistance, which ensures the reliability of time delay.
Description
technical field [0001] The invention belongs to the field of fire protection, and in particular relates to an ignition delay detonation device for a dry powder fire extinguishing bomb and a dry powder fire extinguishing bomb. Background technique [0002] Dry powder fire extinguishing bomb is an efficient and ideal fire extinguishing equipment. Its raw materials are non-toxic, tasteless and harmless to the environment. It is suitable for fire control in forest areas, factories, mines, homes, hotels and other places. [0003] At present, the existing dry powder fire extinguishing bombs in the market are mixed with good and bad quality. Some products have not taken effective moisture-proof measures, and after a certain period of storage of fire extinguishing bombs, the proportion of "dud bombs" is very large, which not only affects fire extinguishing, but also leaves potential safety hazards. [0004] Some products have caused injuries to users due to quality problems. Accor...
