Who knows the principle of rapid inflation of life jackets

HS-YZ type waist pack type automatic inflatable "inflatable life jacket" inflatable front airbag folded and packed in the bag, connected with nylon belt and buckle tied to the waist, when the person falls into the water, the automatic valve immersion spring stretches to open the inflation valve, 2 seconds to quickly inflate, the airbag automatically stretches out of the bag to float the human body to the surface. HS-YZ type waist pack type automatic inflatable "inflatable life jacket" inflated from the waist bag collapses out of an oblong air bag like a bib and connects with the waist bag to surface the human body, at this time, the air bag is put around the neck and held with both hands, generating 16 kg of buoyancy in the water and automatically righting the human body, leaning back 45 degrees and floating on the water with the face facing up. HS-YZ type waist bag type automatic inflatable "inflatable life jacket" inflatable model before wearing is very lightweight, like a small waist bag with nylon straps and buckle connections tied around the waist, when the person falls into the water, the automatic valve immersion spring stretches to open the inflation valve, 2 seconds quickly inflated, the human body is floated to the surface to achieve life-saving.

Pull the pull rope on the inflator forcefully, so that the pull rod is turned to no less than 90 degrees, the needle pierces the diaphragm in the high-pressure gas storage cylinder (disposable, replaceable), and the high-pressure carbon dioxide gas rushes into the air bag, and the gas expands to produce buoyancy.

Inflatable life jackets are mainly composed of sealed inflatable vest airbags, miniature high-pressure gas cylinders and quick inflation valves, etc., and are often used in jobs where there is a possibility of falling into water. Under normal circumstances (not inflated), the entire inflatable life jacket is draped on people's shoulders and backs like a ribbon, and because of its small size, it does not hinder people's freedom of operation; Once it falls into the water, it can be inflated into a life jacket with 8 15 kg of buoyancy in 5 seconds when it encounters danger in the water and needs buoyancy, or it can be automatically inflated and inflated according to the action of the water (fully automatic inflatable life jacket), or the cable on the inflatable valve is pulled by a person (manual inflatable life jacket); The life jacket lifts the human body upwards so that the head and shoulders are exposed to the water, so that they can be safely protected in time.

The self-inflating life jacket is mainly composed of an airbag, a small high-pressure gas cylinder and an automatic inflatable valve, which is suitable for use in the sea and waterside work activities. Under normal circumstances (not inflated), the whole inflatable life jacket is worn on the human body like a vest, the product is lightweight, small, and does not hinder people from working when worn, overcoming the undesirable characteristics of traditional foam life jackets such as bulky and stuffy.

Once it falls into the water, the airbag will automatically inflate and inflate into a life jacket and lifeboat with more than 15 kg of buoyancy within 5 seconds, so that the person's head and shoulders will rise to the surface and provide safety protection. When the wearer's head falls into the water first or is unconscious due to injury, the water entry position can be automatically adjusted so that the head is always facing up, which can provide the best safety rescue.

The principle of life jacket: according to the action of water, automatic inflation and inflation of life jackets, automatic inflation of life jackets, or pull the cable on the inflation valve by hand, manual inflation of life jackets, it will be inflated within 5 seconds to produce 8 15 kg of buoyancy, upward support of the human body, so that the head and shoulders of the person who accidentally fall into the water are exposed to the water, and safety protection is obtained in time.

Buoyant material filled life jacket, that is, made of nylon cloth or neoprene, with buoyant material filled in the middle. The inflatable life jacket is made of high-strength waterproof material, similar to the principle of inflatable lifebuoy or swimming ring, and is divided into automatic inflatable or passive inflatable type.

Life jacket introduction:A life jacket, also known as a life vest, is a life-saving clothing designed similar to a vest, made of nylon fabric or neoprene buoyancy material or inflatable material, reflective material, etc. The general service life is 5-7 years, and it is one of the life-saving equipment on ships and planes.

It is generally a vest type, made of styrofoam or cork, etc. It has enough buoyancy to allow the head of the person who has fallen into the water to be exposed to the water.

Before or after falling into the water, pull the pull rope on the inflator forcefully, so that the pull rod is turned to no less than 90 degrees, the needle punctures the diaphragm of the gas cylinder, and the high-pressure CO2 gas rushes into the air bag, and the gas expands to produce buoyancy. 2.Auto-inflat:

After falling into the water, the life jacket is immersed in the water, which softens the water-sensitive element in the automatic device, the firing pin loses its blockage, and the spring extension pushes the firing pin to puncture the sealing membrane of the gas cylinder and the CO2 gas is filled into the airbag to generate buoyancy. 3.The mouthpiece is a one-way valve type, and the one-way valve automatically closes after blowing.

The compressed air cylinder is injected with high-pressure air, attached to the life jacket or life raft, and the pipeline valve is opened, and the high-pressure air is automatically inflated into the air bag with low air pressure (generally no air) in the life jacket or life raft.

Automatic inflation: After falling into the water, the life jacket is immersed in water to soften the water-sensitive elements in the automatic device, the firing pin loses its blockage, and the spring extension pushes the firing pin to puncture the sealing membrane of the gas cylinder and the CO2 gas is charged into the airbag to produce buoyancy.

Summary. This kind of life jacket is made of high-strength waterproof material, and the inflatable life jacket is mainly composed of a sealed inflatable vest airbag, a miniature high-pressure gas cylinder and a quick inflation valve, etc., and is often used in work where there is a possibility of falling into the water. Under normal circumstances (not inflated), the entire inflatable life jacket is draped on people's shoulders and backs like a ribbon, and because of its small size, it does not hinder people's freedom of operation; Once it falls into the water, it can be inflated into a life jacket with 8 15 kg of buoyancy in 5 seconds when it encounters danger in the water and needs buoyancy, or it can be automatically inflated and inflated according to the action of the water (fully automatic inflatable life jacket), or the cable on the inflatable valve is pulled by a person (manual inflatable life jacket); The life jacket lifts the human body upwards so that the head and shoulders are exposed to the water, so that they can be safely protected in time.

The self-inflating life jacket will be immersed in water after falling into the water, so that the water-sensitive element in the automatic device will be softened, the firing pin will lose its blockage, and the spring extension will push the firing pin to puncture the sealing diaphragm of the gas cylinder, and carbon dioxide gas will be filled into the air bag to produce buoyancy.

The principle of the kind of life jacket that inflats as soon as it is pulled is detailed and it is best to have a picture.

Change the question. This kind of life-saving ambush suit is made of high-strength waterproof material, and the inflatable life jacket is mainly composed of a sealed inflatable vest airbag, a miniature high-pressure gas cylinder and a quick inflation valve, etc., and is often used in work where there is a possibility of falling into the water. Under normal circumstances (not inflated), the entire inflatable life jacket is draped on people's shoulders and backs like a ribbon wearing finger blade, which does not hinder people's freedom of operation due to its small size; Once it falls into the water, it can be inflated into a life jacket with 8 15 kg of buoyancy in 5 seconds when it encounters danger in the water and needs buoyancy, or it can be automatically inflated and inflated according to the action of the water (fully automatic inflatable life jacket), or the cable on the inflatable valve is pulled by a person (manual inflatable life jacket); The life jacket lifts the human body upwards so that the head and shoulders are exposed to the water, so that they can be safely protected in time.

The self-inflating life jacket will be immersed in the water after falling into the water, so that the water sensitive element in the automatic device will be softened, the firing pin will lose its blockage, and the spring will be extended to push the firing pin to pierce the sealing diaphragm of the gas cylinder, and the carbon dioxide gas will be filled into the gas chamber and generate buoyancy.

What kind of clothes can instantly and automatically expand when a person is unconscious at home.

Airbag anti-fall suit, dear.

Like the principle of car airbags, the lowest price is more than 300.

The principle of life jacket: according to the action of water, automatic inflation and inflation of life jackets, automatic inflation of life jackets, or pull the cable on the inflation valve by hand, manual inflation of life jackets, it will be inflated within 5 seconds to produce 8 15 kg of buoyancy, upward support of the human body, so that the head and shoulders of the person who accidentally fall into the water are exposed to the water, and safety protection is obtained in time.

The principle of the lifeboat: there is a compressed air cylinder inside, and the air cylinder has two outlets, the first is to connect the cable from the FRP storage barrel and connect it to the ship's side guardrail, and the other end of the cable has an air outlet when it is in the air of another air outlet, and then the other air outlet is directly connected to the raft body, and finally you throw the life raft down due to the limited length of the cable, and when the weight of the raft itself falls, the air outlet baffle will fall open, and the gas in the compressed air bottle will enter the raft body at a fast speed to complete the inflation.

After reading the answers upstairs, I understood.

Hello dear, mostly orange and red, because orange and red life jackets are more eye-catching and easy to find. And for those who fall into the sea, orange-red is a color to avoid attacks by ferocious fish such as sharks. Because sharks are sensitive to this color and do not approach easily, they are safer for those who fall into the water.

At present, the common life jacket on the market is a vest type, the outer fabric is mostly nylon or neoprene, and the inside is filled with buoyant materials such as foam or cork. In addition, there is a high-strength waterproof material made of virtual mold, which is inflated on the inside of the life jacket to achieve the effect of floating.

Summary. 1. Put the life jacket around your neck and place the rectangular buoyancy bag in front of you; Tie the straps at the neckline. 2. Thread the left and right straps through the buckle loops on the left and right sides respectively, and cross them behind the back; 3. Thread the strap through the buckle loop on the chest and tie the dead knot.
