Anti-explosion binary packaging bag and simple fire extinguisher using it

Abstract

The invention discloses a drop-proof, explosion-proof binary packaging bag and a simple fire extinguisher using the same. The binary packaging bag includes a bag body, an aerosol valve liquid introduction pipe, and the bag body is heat-sealed by two sides and a bottom surface , the upper and both sides of the two sides correspond to heat sealing respectively, the lower sides of the two sides are respectively heat-sealed with the periphery of the bottom surface, the bottom surface and the sides are combined in an arc, and then the lower sides of the two sides correspond to heat sealing again, and the bottom surface contains Inside, the lower side of the bag body is beveled on both sides and the middle is straight; there is an outlet on the upper side, and the aerosol valve is inserted into the outlet and placed in the bag with the upper end protruding, and is heat-sealed with the bag at the outlet. The upper side has downward slopes on both sides of the outlet; the diameter of the bag body after swelling is greater than the inner diameter of the fire extinguisher tank. The present invention aims at the burst position reflected in the simple fire extinguisher drop test of the binary packaging bag, improves its structure in a targeted manner, improves its structural strength, significantly improves the burst phenomenon when dropped, and satisfies GA 86‑ The 2009 regulations on simple fire extinguishers provide quality assurance for large-capacity fire extinguishers with binary packaging bags.

Description

technical field [0001] The invention relates to a binary packaging bag and a simple fire extinguisher using the binary packaging bag, in particular to a binary packaging bag and a simple fire extinguisher meeting the drop test requirements. Background technique [0002] The simple fire extinguisher produced by our company adopts GB 13042-2008 packaging container iron aerosol can, GB19741-2005 plastic composite film bag for liquid food packaging (WLSZ film, also known as binary packaging bag), GB / T 17447-2012 The aerosol valve, etc., and the fire extinguishing agent are packed in binary packaging bags. The fire extinguisher products must meet the regulations of GA 86-2009 simple fire extinguishers. Among them, the binary packaging bags have the following problems: [0003] 1. Our company's fire extinguishing agent is a strengthening liquid with a large specific gravity (1.214 g / ml). Compared with the domestic aqueous film-forming foam fire extinguishing agent (1.07 g / ml), th...

Problems solved by technology

[0003] 1. Our company's fire extinguishing agent is a strengthening liquid with a large specific gravity (1.214 g / ml). Compared with the domestic aqueous film-forming foam fire extinguishing agent (1.07 g / ml), the same volume and weight difference are also large, which leads to the drop test of the fire extinguisher Therefore, the existing domestic binary packaging bags cannot meet the requirements of the GA 86-2009 simple fire extinguisher drop test for our company's fire extinguishing agents.

[0004] 2. The capacity of the most used European Swiss binary packaging bag in the industry cannot meet the weight of the agent for our company's fire extinguisher products. The world's thin-walled aluminum cans without welds cannot be produced because of the capacity of this binary packaging bag. Fire extinguisher products with an agent weight of more than 900ml

[0005] Domestic GB 19741-2005 plastic composite film bags for liquid food packaging, the material is relatively simple, and the drop performance of the packaging bags greater than 500ml and less than or equal to 1000ml can only guarantee a height of 600mm

It is not feasible to increase the strength of the bag by simply increasing the wall thickness
