Its two, oxygen supply equipment is when finite volume, and the oxygen of storage wants many, to extend working time.
Summary of the invention
The object of this invention is to provide a kind of oxygen supply equipment when finite volume, the oxygen of storage is many, namely ensures the safety of human life, human comfort, and oxygen of limiting the quantity again exports, and in the cabin extending oxygen service time, compressed oxygen controls ventilation channel.
The object of the present invention is achieved like this, in cabin, compressed oxygen controls ventilation channel, it is characterized in that: comprise compressed oxygen cylinder group, each group delivery outlet of compressed oxygen cylinder group has gas cylinder regulator, gas cylinder regulator is by connection by metal hose first ball valve, oxygen supply bus-bar is connected to by the first ball valve, oxygen supply bus-bar divides two-way, one tunnel connects the second ball valve, another road connects inflow-rate of water turbine valve successively, 3rd ball valve, second depressurized device, 5th ball valve, metering pin valve, noise damper exports, flow meter is serially connected with in metering pin valve front end, the oxygen output quantity of compressed oxygen cylinder group is obtained by flow meter.
Described the 5th has pressure meter between ball valve and metering pin valve, to obtain the oxygen output pressure of compressed oxygen cylinder group.
There is the 4th ball valve between described second depressurized device and the 5th ball valve, when compressed oxygen cylinder group pressure is excessive or have problem between oxygen delivery outlet, alleviating pipeline pressure by controlling the 4th ball valve.
The compressed oxygen cylinder capacity of described compressed oxygen cylinder group is 40 liters.
Described compressed oxygen cylinder group has three groups of compressed oxygen cylinders.
Advantage of the present invention: in the present invention, the advantage of invention has two: first adopt low pressure to conflux, after the 0.3MPa that first reduced pressure to by the oxygen in gas cylinder, the mode that low pressure is confluxed, avoids the infringement of high pressure draught to metal hose, extend the life-span of flexible pipe.Secondly; circuit design inflow-rate of water turbine valve; play defencive function to the overvoltage of pipeline, overcurrent, namely as pressure reducer breaks down, pipeline pressure increases suddenly (being greater than 0.5 MPa) when causing flow to increase; inflow-rate of water turbine valve cuts out automatically; play a protective role to ventilation channel below, oxygen feeding stop, prevents flow excessive; cause oxygen concentration too high levels, cause oxygen-intoxication.
