Description
Technical field
The utility model belongs to diving apparatus field, especially a kind of to take the double air supply system enclosed circulations not depressurized certainly
Aqualung.
Background technique
Aqualung can be divided into open type aqualung according to the Land use systems of gas and enclosed circulation diving is exhaled
Haustorium.
Open type aqualung is mainly by 1 12L gas cylinder, 1 one-level pressure relief valve, a two-level controller and several pipelines
Composition.Diver is using the principle that open type aqualung is dived under water: the 20MPa pressure-air in compressed gas cylinder is depressurized by level-one
Valve and two-level controller are decompressed to environmental pressure locating for diver, then are smoked by diver；After diver breathes, then pass through
It is discharged into environment waters by two-level controller.In this respiratory, gas is unidirectionally to be discharged into water, but diver exhales
In the every mouth air of suction, the oxygen being effectively utilized is not participating in the new old of human body less than 20%, more than 80% oxygen
It is metabolized and is directly discharged, this has resulted in great waste.The 20MPa air bottle that one bottle of volume is 12L only reaches diver
It uses 30 minutes or so under water.
Enclosed circulation aqualung and the maximum difference of open type aqualung are can to recycle diver to exhale
Each gas out absorbs the carbon dioxide of diver's exhalation by carbon-dioxide absorbent, after the gas of exhalation is cleaned
It is repeated to absorb by diver again, is reached with this and recycle purpose.Meanwhile in each breath cycle, enclosed circulation is latent
Aquatic respiration device only requires supplementation with the oxygen that human consumption is fallen.Therefore, the gas cylinder that enclosed circulation aqualung carries is very
Small, the enough divers of 20MPa oxygen cylinder that a volume is 1L use more than 120 minutes under water.
The problem of enclosed circulation aqualung can encounter two physiologically when in use: one is oxygen poisoning (oxygen
Pressure is more than that certain value may will lead to oxygen poisoning), the other is decompression (excluding internal nitrogen).
The enclosed circulation aqualung that can be seen currently on the market is external production, in order to avoid diver's oxygen
Poisoning, according to constant partial pressure of oxygen principle, the partial pressure of oxygen in respirator is monitored using oxygen probe, manual further according to current partial pressure of oxygen
Or diluent gas is injected from trend respirator maintain the partial pressure of oxygen in enclosed circulation aqualung in safety value.
This design operation is complicated, needs ceaselessly to pay close attention to oxymonitor, and adjust partial pressure of oxygen in due course.Its maintenance cost simultaneously
Also very high, the cost that a set of enclosed circulation aqualung replaces oxygen probe every year is just not less than 300 dollars (can only import),
A set of open type aqualung is bought enough.
Also very complicated on decompression program, it needs to execute decompression program according to the regulation on diving decompression table, this needs
Diver oneself calculates the carry-on dive computer of decompression time or purchasing expensive to calculate the decompression time.
Using complexity, maintenance cost is high, and decompression time is long, these all allow enclosed circulation aqualung militarily
Using causing big inconvenience.

The working principle of the utility model is:
Oxygen cylinder valve is opened, oxygen divides two-way to enter air-breathing bag by oxygen pressure reducing valve.Nozzle is compared by pure oxygen surely all the way
Valve continuously supplies the oxygen of fixed amount into air-breathing bag, and when diving depth is more than 7 meters, pure oxygen is fixed to close than nozzle group valve
It closes.Another way is supplied by oxygen check valve and automatic supply and demand valve into air-breathing bag.When the fixed oxygen supplied than nozzle group valve of pure oxygen
When measuring inadequate, air-breathing bag formation negative pressure, automatic supply and demand valve is opened to be supplied into air-breathing bag.
Nitrogen oxygen cylinder valve is opened, nitrogen oxygen atmosphere divides two-way to enter air-breathing bag by nitrogen oxygen pressure reducing valve and spanner shut-off valve.
Continuously supply the nitrogen oxygen atmosphere of fixed amount into air-breathing bag by nitrogen oxygen nozzle group valve all the way.Another way is stopped by nitrogen oxygen
It returns valve and automatic supply and demand valve is supplied into air-breathing bag.When spanner shut-off valve is opened, since the outlet pressure of nitrogen oxygen pressure reducing valve is set
Definite value is greater than the outlet pressure setting value of oxygen pressure reducing valve, and oxygen gas circuit is automatically closed, does not resupply pure oxygen at this time, only supply nitrogen
Oxygen gas mixture.
Air supply system injects fresh oxygen to air-breathing bag, is then smoked by hose to one-way breather valve for diver,
The gas of diver's exhalation enters one-way breather valve and passes through that hose enters exhaling bag and carbon-dioxide absorbent tank purifies again,
It finally returns air-breathing bag and completes a circulation, smoked next time for diver.Broken bubble exhaust valve is installed, when exhaling on exhaling bag
When pressure in airbag is more than setting value, extra gas will be discharged in broken bubble exhaust valve, emerged in the form of small broken bubble.
Floating vest is connect by manual aerator and pipeline with spanner shut-off valve, and inflation button is pressed, can be to buoyancy
Vest inflation.
Although disclosing the embodiments of the present invention and attached drawing for the purpose of illustration, those skilled in the art can be with
Understand: departing from the utility model and spirit and scope of the appended claims, various substitutions, changes and modifications are all can
