The Principle and Usage of Inflatable Life Jackets

Inflatable life jackets are made by forcefully pulling the pull rope on the inflation device, causing the pull rod to rotate at least 90 degrees. The needle pierces the diaphragm in the high-pressure gas storage cylinder (disposable, replaceable), and high-pressure carbon dioxide gas rushes into the airbag. The gas expands to generate buoyancy, thus achieving the purpose of life saving.

Inflatable life jackets mainly consist of sealed inflatable vest airbags, miniature high-pressure gas cylinders, and quick inflation valves, and are often used in work with the possibility of falling into the water.

Under normal circumstances (not inflated), the entire inflatable life jacket is worn as a belt and draped over a person's shoulder. Due to its compact size, it does not hinder people's freedom of operation; Once falling into the water and encountering a danger that requires buoyancy in an emergency, it can automatically expand and inflate according to the action of the water (fully automatic inflatable lifejacket), or manually pull the cable on the inflation valve (manual inflatable lifejacket), which will complete inflation within 5 seconds to generate 8-15 kilograms of buoyancy, lift the human body upwards, and expose the head and shoulders of the person who accidentally fell into the water to obtain safety protection in a timely manner.
