Pulling force on the rope on the inflatable device aviation lifejacket, so that the lever does not go less than 90 degrees, the puncture needle to break the high-pressure gas cylinders (disposable, replaceable) of the diaphragm, high pressure carbon dioxide gas into the air bag, gas expansion After buoyancy. Inflatable lifejackets inflatable vest mainly by sealing balloon, miniature high-pressure cylinders and rapid inflation valves and other components, there is the possibility of falling into the water at work often. Under normal circumstances (not inflated), the entire inflatable lifejacket worn wrapped like a ribbon on a person's shoulder, due to small size, does not prevent the operation of the free people; once fell into the water, the buoyancy of the water needs of danger emergency, or self-inflating inflatable (automatic inflatable lifejacket) According to the action of water, or from person to pull the cable (manual inflatable life jackets) inflation valve on within 5 seconds of time can become inflated having 8 to 15 kg buoyancy lifejacket; Lifejacket hold up the body, the head, shoulders out of the water, which can be obtained in a timely manner inflatable lifejacket safety guarantee there with manual and automatic inflatable inflatable two functions. 1. Manual Inflatable: Before or after the force pulling the rope fell into the water on inflatable devices, so that the lever go to not less than 90 degrees, the thorn pierce the diaphragm cylinder, high-pressure CO2 gas into the airbag, resulting buoyancy after gas expansion. 2. Automatic Inflatable: lifejacket after immersion in water so that the water inside the automatic device to soften water-sensitive components, the striker loses the barrier, stretching springs push the striker punctured diaphragm seal CO2 gas cylinder filled balloon to produce buoyancy. 3. mouthpiece for a one-way valve, after blowing a one-way valve is automatically closed. Frequently Asked Questions: 1. Q: Are inflatable lifejacket is disposable? A: You can use inflatable lifejacket three to five years, accessories are disposable and can be replaced. 2, Q: Are inflatable lifejacket with dumped supporting the use? A: Yes, we produce inflatable life preserver belt has been dumped successful cooperation with domestic manufacturers, can throw the hands, throwing Korea, the United States and supporting the use of throw.
