Flow into carbon fibre composite high-pressure oxygen cylinder.
The content of the invention
Goal of the invention：It is rational in infrastructure to provide one kind, is easy to connect, is easily installed, safe and reliable new unidirectional oxygenation turns
Joint, ensure ground crew or user when being oxygenated to carbon fibre composite high-pressure oxygen cylinder, quickly can be oxygenated with ground
Car matching connection, and oxygen source is maintained under stable pressure and flow into oxygen cylinder and process is irreversible.
Technical scheme：1. a kind of unidirectional oxygenation adapter of aircraft oxygen system, by block (1), pad (2), connects mouth
(3), valve base (4), spring (5), curved mouth (6), packing ring (7), clamping nut (9), valve (11), chain assemblies (12) composition；
The adapter divides air inlet connecting mouth point and check valve part；The air inlet connecting mouth point mainly by block (1), pad (2),
Mouth (3), chain assemblies (12), clamp nut (9) composition are connect, the clamping nut (9) installed inside the air inlet connecting mouth, plays and fills
Metering function during oxygen, the ring flange on air inlet connecting mouth external shell play a part of being easily installed, and air inlet connecting mouth housing right-hand member has
Internal thread is used for fixed described check valve part；Air inlet connecting mouth housing left port is designed with external screw thread and filled for connecting ground
Oxygen car joint；The check valve part is made up of valve base (4), valve (11), spring (5), packing ring (7), curved mouth (6), institute
It is internal installed in curved mouth (6) to state valve base (4), valve (11), by the spring (5) of valve (11) bottom, plays one-way flow
Effect；Curved mouth (6) external shell left end is designed with external screw thread and air inlet connecting mouth point connection, curved mouth (6) external shell right-hand member
External screw thread is designed with, connecing mouth with oxygenation connecting conduit matches connection.
The left end of the air inlet connecting mouth housing is also equipped with block (1), pad (2) and chain assemblies (12), when need not fill
During oxygen, block (1) and pad (2) can avoid the generation that dust enters；During oxygenation, chain assemblies (12) can hang block (1)
In air inlet connecting mouth, it is easy to subsequent operation.
Screen pack A (8) is installed between the clamping nut (9) and air inlet connecting mouth housing, played a role in filtering.
Screen pack B (10) is installed between described air inlet connecting mouth and check valve, plays further filtration.
In summary, after source of the gas connects mouth by ground oxygen dispenser into oxygenation, the compression spiral shell connect inside mouth is first passed around
Female and screen pack current limliting and filtering, source of the gas make the spring inside check valve that elastic deformation occur, and valve is subjected to displacement, oxygen
Stored through being flowed to inside valve in endpiece carbon fibre composite high-pressure oxygen cylinder, complete the oxygenation program to oxygen cylinder.
The beneficial effects of the invention are as follows：Oxygen system of the present invention is unidirectionally oxygenated adapter and solves certain type transporter oxygen system
System ground oxygen dispenser matches connectivity problem with oxygen system on machine.When being oxygenated using ground oxygen dispenser, the present invention can be quick
Connection is matched with ground oxygen dispenser, and oxygen source is maintained under stable pressure and flows into oxygen cylinder and process is irreversible；When winged
During administrative staff's normal use oxygen, the present invention can guarantee that oxygen source will not be from gas leakage at oxygenation adapter；
Brief description of the drawings
