The working principle of quick diving dress inflation system of escaping danger:
Diving dress inflation system of quickly escaping danger is fixed in Quick-pressing cabin, controller lower end air inlet and Quick-pressing cabin
Middle pressurized air source connection.When installation, it is desirable that the center line of air bag connection valve is located at 0mm~75mm model above 1 center line of controller
In enclosing.
Illustrate the inflation system course of work for completing primary process of escaping danger.Original state, Quick-pressing are calmed the anger in cabin
Body enters inflation system controller, and feeds air bag connection valve by supply air line, increases air bag connection valve chamber pressure, this
A pressure feeds back to controller feedback cavity by feedback pipe, increases controller feedback cavity pressure.When feedback cavity pressure
When more than the sum of controller compensation cavity pressure and spring pressure, pushes valve rod to move to left, close controller, gas does not enter back into
Air bag connection valve.
After operating personnel enters Quick-pressing cabin, the gas-charging connection quickly escaped danger on diving dress and inflation system air bag are connected
The connection of valve inflatable interface is connect, air bag connection valve is opened, and gas enters diving dress air storage bag of quickly escaping danger, at this time in air bag connection valve
Pressure reduction, the gas in controller feedback cavity enter in air bag connection valve, and feedback cavity pressure reduces, and lead to feedback cavity internal pressure
Power forces valve rod to move to right lower than the sum of spring force and compensation cavity pressure, and controller is opened, and gas enters gas by supply air line
Capsule connection valve, and then enter diving dress air storage bag of quickly escaping danger.Diving dress gas storage intraluminal pressure of quickly escaping danger constantly increases, namely
Pressure and controller feedback cavity pressure constantly increase in air bag connection valve, when feedback cavity pressure is more than spring pressure and control
When device compensates the sum of cavity pressure, push valve rod to move to left, close controller, gas does not enter back into air bag connection valve, stop be
Diving dress of quickly escaping danger supplies, and the quick diving dress air storage bag of escaping danger of protection will not be ruptured due to hypertonia.
If operating personnel is in Quick-pressing cabin accidentally by diving dress gas-charging connection and the air bag connection valve of quickly escaping danger
When disengagement, air bag connection valve is closed, pressure rise in air bag connection valve, increases controller feedback cavity pressure, controller closes
It closes.When diving dress gas-charging connection of quickly escaping danger is connect by operating personnel with air bag connection valve again, air bag connection valve is opened, gas
Body flows into diving dress air storage bag of quickly escaping danger, and pressure reduction in air bag connection valve reduces controller feedback cavity pressure, control
Device is opened, and gas supply is restored.
When operating personnel completes Quick-pressing, after leaving Quick-pressing cabin, Quick-pressing cabin drainage pressure-reducing.Add with quick
The rapid decline of pressure in ballasting, the safety valve in air bag connection valve are opened, and excessive gas is discharged, protect air bag connection valve with
And feedback pipe and supply air line.
