Abstract
A gas used as the gas source for auto-inflated personal life-buoy contains monofloroethane, difluoroethane, and difluoromethane or their mixture. Its advantages are high safety, no environmental pollution and no damage to ozonosphere.
Description
The present invention relates to the gas of air heave type water life saving apparatus.
Drowned is one of China's three big unexpected causes of the death, and situation is very serious.Because drowned is sudden accident often, conventional fixed floatage-type life jacket is too big because of volume, can't take with oneself whenever and wherever possible, therefore can't fundamentally solve the drowned problem of death of China.The air heave type water life saving apparatus can be made very little shape, and not taking with oneself at any time to influence work, health and swimming exercise, and be inflated to life jacket or buoy quoit when in danger automatically and the people is rescued, thereby significant.Automatically the air heave type buoyant apparatus is made up of air bottle, air bag and start-up control system, liquefied gas is charged into air bag generation buoyancy the people is rescued.The inventor develops gas specially and opens formula buoyant apparatus more than ten years, has invented the patent No. and be multinomial products such as 85205258,89102871,90226867.8, knows very well the used gas of buoyant apparatus to have great role for buoyant apparatus allomeric function and penetration and promotion.Buoyant apparatus in the past is gases used mainly to be carbon dioxide, alkane, chlorofluoro-alkane.But the carbon dioxide boiling point is too low, air pressure is too high, and air bottle must have very high strength, and dress gas must have special equipment, and troublesome poeration is difficult for penetration and promotion; The alkane comb. is too big, can not use separately; The chlorofluoro-alkane contaminated environment is destroyed atmospheric ozone layer.
The objective of the invention is to seek the source of the gas that new gas is made for single automatic air heave type water life saving apparatus.It has safety performance, destruction atmospheric ozone layer free from environmental pollution, and boiling point and air pressure are moderate, and is easy to operate.
It is reported, replace the cryogen of chlorine-containing compound in order to seek new gas both at home and abroad, applied for multinomial patent as refrigerator, A/C.The inventor finds that through overtesting a fluoroethane, Difluoroethane and difluoromethane are the idea1 gases of making single automatic air heave type buoyant apparatus source of the gas.These three kinds of gases can use separately, also can mix use mutually, can also mix other gases of a part (such as alkane) and use.In the air bottle of packing into of above-mentioned gas liquefaction back when commercially available (general with the liquefied gas supply of material) as the source of the gas of buoyant apparatus, air bottle connects air bag, make the gas in the air bottle charge into air bag generation buoyancy by modes such as manual automatic inflation type, heavy water automatic inflation type, chance water automatic inflation types, the drowning person is rescued.
The character of these three kinds of gases is as follows: a fluoroethane, molecular formula are CH
3CH
2F, boiling point-37.7 ℃, mol wt is 48; Difluoroethane, molecular formula are CH
3CHF
2, boiling point-24.7 ℃, mol wt is 66; Difluoromethane, molecular formula are CH
2F
2, boiling point-52 ℃, mol wt is 52.These three kinds of materials are not chloride, do not destroy atmospheric ozone layer, do not fire, and safety, boiling point and air pressure are moderate, operation easily, used chlorofluoro-alkane F before its molecular weight ratio
12Little a lot, according to chemical law, the more little volume that produces of its mol wt of the gas of identical weight (also being buoyancy) is big more, and therefore in order to obtain certain buoyancy, the desired gas amount just can reduce, and air bottle diminishes, and the buoyant apparatus volume weight has also diminished.
These three kinds of gases and composition thereof are applicable to the automatic air heave type water life saving apparatus of various types (clothing), and for the drowned problem of death that solves China, rescue drowning person life is eliminated environmental pollution and all had a very important role.
Claims (1)
- A kind of gas of making single automatic air heave type buoyant apparatus source of the gas, pack into after its liquefaction in the air bottle of buoyant apparatus, after starting, charge into air bag and produce buoyancy, it is characterized in that a fluoroethane, Difluoroethane, difluoromethane or they each other compound or with the compound of other gas.
