in addition, it should be noted that: when damaged position and check valve were close to, can arouse that the lower extreme space is not enough, will aerify the one end of connector this moment and install on the valve body, adjust check valve length according to actual need to this realizes normally covering the gas leakage region, further improves the practicality.
In addition, the invention also discloses a use method of the safety bag for the life line of the ultra-high molecular polyethylene fiber, which is characterized in that: the method comprises the following steps:
when in carrying:
s1 air leakage: opening an exhaust valve of the safety bag, and manually squeezing the safety bag to discharge the gas in the safety bag;
s2 folding: the side, where the zipper is not arranged, of the air bag with the air leakage opening being shriveled is folded for the first time along the horizontal center line to the back of the air bag, and then the air bag is folded for the second time along the vertical center line after the first folding, so that the zipper strips are ensured to be exposed;
s3 storage: the zipper strips are butted and pulled to 2/3, articles such as life ropes and the like are placed into a space formed by jointing the zipper strips after the air bags are folded, the zipper strips are thoroughly tensioned, and storage is realized.
When in lifesaving use:
s1 preparation before inflation: unzipping the zipper, taking out the life-saving rope, opening the safety bag and paving the safety bag, adjusting the length of the one-way valve on the ventilation area, then opening the inflation connector, connecting the air outlet head of the inflation device to the one-way valve, and closing the inflation connector;
s2 inflation: the air charging device is started, air is fed into the air charging device, meanwhile, pressure is applied to the compressed air feeding part, air in the outside air is fed into the air storage cavity of the sealing bag through the air feeding pipeline and along the spare air feeding channel, the coanda effect is formed, the airflow is guided through little compression, the airflow generates the wall attachment effect in the airflow channel, negative pressure is generated at the air inlet port of the air inlet pipe, the huge air draft effect is generated to the outside, and the air inlet efficiency of the air inlet is improved;
s3 uses: and (3) removing the inflating device and the inflating connector, screwing the plugs on the air supply ports, then buckling the connecting buckle of the life-saving rope on the buckle ring of the safety bag, and putting the side of the safety bag without the heat-preservation unit into water for use.
Compared with the prior art, the invention has the beneficial effects that:
when the safety bag is carried, the safety bag is deflated, after being folded, the zipper is used for being pulled up to form a storage space, and then the air faucet is shielded, so that the air faucet is prevented from being damaged, meanwhile, a storage space is formed, tools used in a matched manner can be stored, and the problems that the safety bag is easy to lose and takes time when being stored separately in the prior art are solved; so as to be convenient for carrying and using for field survival;
when the lifesaving device is used for lifesaving, the safety bag is paved, the air charging device is started, air blowing and air supply part pressing are carried out simultaneously, air inlet flow and flow rate are improved, so that air charging is completed quickly, the heat preservation unit floats on the water surface during use, the effect of isolating cold energy transmission is achieved, and therefore the problems of body function reduction and physical strength reduction of a user due to cold energy transmission are solved, and the rescue effect is improved.

3. Compared with the existing air faucet, the air inflation connector has the advantages that the air inlet pipe and the connector of the air inflation device can be respectively sealed and fixed through the through holes at the two ends in the process of connecting the air inlet with the air inflation connector, and the connecting gap between the air inlet pipe and the connector of the air inflation device is located in the closed space of the air inflation connector, so that the phenomenon of air leakage at the connecting position during air inflation is avoided; because the compressible volume of the gas is far greater than that of the liquid, the abundant space formed by the hollow structure of the inflation connector plays a good role in buffering the internal pressure rise caused by liquid leakage and leakage stopping operation at the same time, the first semi-cylindrical ring and the second semi-cylindrical ring are prevented from being locked difficultly, and the inflation connector can be detached, so that when an inflation device is not arranged in the field, the inconvenient influence cannot be caused during manual air blowing;
in addition, when the pipeline with the air inlet is damaged in the field use, the through holes at the two ends of the inflating connector can be wrapped at the two ends of the damaged part of the air inlet pipeline, so that the problem of air leakage is solved temporarily, and the normal use is not influenced when the pipeline exposed in the field is damaged and leaks air;
in addition, it should be noted that: when damaged position and check valve were close to, can arouse that the lower extreme space is not enough, will aerify the one end of connector this moment and install on the valve body, adjust check valve length according to actual need to this realizes normally covering the gas leakage region, further improves the practicality.
In addition, the invention also discloses a use method of the safety bag for the life line of the ultra-high molecular polyethylene fiber, which is characterized in that: the method comprises the following steps:
when in carrying:
s1 air leakage: opening an exhaust valve of the safety bag, and manually squeezing the safety bag to discharge the gas in the safety bag;
s2 folding: the side, where the zipper is not arranged, of the air bag with the air leakage opening being shriveled is folded for the first time along the horizontal center line to the back of the air bag, and then the air bag is folded for the second time along the vertical center line after the first folding, so that the zipper strips are ensured to be exposed;
s3 storage: the zipper strips are butted and pulled to 2/3, articles such as life ropes and the like are placed into a space formed by jointing the zipper strips after the air bags are folded, the zipper strips are thoroughly tensioned, and storage is realized.
When in lifesaving use:
s1 preparation before inflation: unzipping the zipper, taking out the life-saving rope, opening the safety bag and paving the safety bag, adjusting the length of the one-way valve on the ventilation area, then opening the inflation connector, connecting the air outlet head of the inflation device to the one-way valve, and closing the inflation connector;
s2 inflation: starting the air charging device, feeding air into the air charging device, applying pressure to the compressed air feeding part, and feeding the air in the outside air into the air storage chamber of the sealing bag through the air feeding pipeline and along the spare air feeding channel;
s3 uses: and (3) removing the inflating device and the inflating connector, screwing the plugs on the air supply ports, then buckling the connecting buckle of the life-saving rope on the buckle ring of the safety bag, and putting the side of the safety bag without the heat-preservation unit into water for use.
Compared with the prior art, the invention has the beneficial effects that:
when the safety bag is carried, the safety bag is deflated, after being folded, the zipper is used for being pulled up to form a storage space, and then the air faucet is shielded, so that the air faucet is prevented from being damaged, meanwhile, a storage space is formed, tools used in a matched manner can be stored, and the problems that the safety bag is easy to lose and takes time when being stored separately in the prior art are solved; so as to be convenient for carrying and using for field survival;
when the lifesaving device is used for lifesaving, the safety bag is paved, the air charging device is started, air blowing and air supply part pressing are carried out simultaneously, air inlet flow and flow rate are improved, so that air charging is completed quickly, the heat preservation unit floats on the water surface during use, the effect of isolating cold energy transmission is achieved, and therefore the problems of body function reduction and physical strength reduction of a user due to cold energy transmission are solved, and the rescue effect is improved.
