? ? ? ?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.
