Description:

?

1, the submarine has a number of storage positions. When the submarine to dive into the

water in the water tank, the submarine weight increased more than its displacement, the

submarine will dive.Drainage by compressed air.
2, the analysis of the force in the process of the two dynamic processes of the sinking and

floating of the object in the liquid. The submarine submerged in the water, the volume of

water change is no longer, by its buoyancy is constant, control its dive depth by the amount

of water in the water tank (namely the change of gravity) to achieve the change. When the

water in the cabin of the water remains unchanged, the submarine underwater in a deep is

suspended rather than sink.
3, the submarine is a kind of military vessels, it can dive underwater, reconnaissance

and attack.
4 people according to the principle of ups and downs successfully made the submarine, the

fighting in the underwater ship in the previous battle shows its fighting capacity, it can dive

from the surface to a depth of 500 meters, has good concealment and endurance, from

underwater attack surface ships and land targets, can also be used as a reconnaissance,

mine and transport, initially, people also will stone or lead weights and other heavy loaded

into the submarine, the submarine to sink, remove stone or lead the submarine resurfaced,

the submarine of course can& acute;t dive too deep and trouble, floating and then to dive, but also

from the shore made stone.
5.The principle of submarine is to change the weight of the submarine to achieve. Based on

the & quot;floating law& quot; (or Archimedes& acute;s law).

Product Advantage:

The present invention is further directed to a breathing apparatus structure With a two-stage ? ? ? ? ? ? ? ? ? ? reduced-pressure

spare air bottle head:

1. a high pressure reducing valve,. to enable the air bottle to be reused.

2. in Which a high-pressure air in an air bottle iscompletely blocked by an air bottle head switch,?

so as to avoid.

3. in Which an inhalation mouthpiece onone side of a housing of an air bottle head is designed

to be inclined upWards by a certain angle for the ease of use.
