There is the face shield case of in situ detection function except realizing to quick-don mask supply, disconnect except oxygen, the oxygen supply pressure on all right in situ detection aircraft.As shown in Figure 9, aircraft before take-off, generally can be detected a whole set of oxygen system by face shield case, and being detect oxygen source pressure on aircraft on the one hand, is to verify whether whole face shield case can normally work, with or without gas leak phenomenon on the other hand.This just needs right door assembly to coordinate current indicator jointly to complete the testing of product oxygen pressure.
1) operating mode one: the detection of oxygen pressure under normal circumstances and oxygen supply
Operation principle: the chapters and sections of current indicator principle describe above, when oxygen pressure reaches rated value time, oxygen pressure overcomes the pressure of compression spring, makes axial movement outside, until oxygen supply is switched on.Generally, the using state of face shield case is left in casing by face shield, and face shield is stuck in left and right door assembly.The original state of face shield case is left and right door assembly is closed condition, and when carrying out oxygen pressure detection being does not need to open left and right door assembly taking-up face shield to detect.
Left and right door assembly in off position under, the block 38 on right door assembly just blocks the axle 43 on current indicator assembly, if when oxygen pressure reaches rated value, presses the button 33, and axle 43 outwards will be ejected by oxygen pressure, oxygen supply connect, have oxygen supply range cover.In the moment that oxygen is connected, the display diaphragm 411 on current indicator is heaved owing to producing larger pressure reduction, and prompting oxygen supply is connected, and operating personnel can directly observe.If display diaphragm 411 can be observed to be heaved, just illustrate that oxygen pressure is normal, face shield case is working properly.Release button 33, block 38 sets back, and axle 43 is pushed back to original state, and oxygen is closed.
Under the state that left and right door assembly is closed, even if oxygen pressure reaches rated value, if do not operate button 33, oxygen supply also cannot be connected, because the oxygen pressure of current indicator inside is not enough to the large stage clip 311 controlling block 38 in right door assembly to push open, so oxygen supply just cannot be connected, do not have oxygen to supply face shield, the safety and reliability of whole oxygen system is guaranteed in this design.If but oxygen pressure does not reach rated value, current indicator then can not work, and presses the button, and whole system is reactionless, and this just illustrates that on aircraft, oxygen pressure is on the low side, needs to carry out oxygen supply.
2) operating mode two: after being opened by door assembly under normal circumstances, the detection of oxygen pressure and oxygen supply
If when oxygen pressure reaches rated value, face shield takes out by occupant from face shield case, and after the constraint lacking door assembly, axle 43 will outwards move, and oxygen supply display is connected, and now has oxygen to face shield.
In this case, need to close door assembly, when but oxygen supply is connected again, only need to close door assembly, below block 38, have individual inclined-plane, under the state that door assembly is closed, block 38 is outwarded winding to side Compress Spring fixed muffle 314 and small pressure spring 315, for axle 43 abdicates enough places, make it continue to keep oxygen supply to connect, see a) figure in accompanying drawing 11; If require when closing door assembly to disconnect oxygen, after just needing to close door assembly, at the secondary button 33 pressed on door assembly, block 38 moves backward, retreats to the end of axle 43, sees the b in accompanying drawing 11) figure, release button 33 can close oxygen, sees the c in accompanying drawing 11) figure.Detection before just can repeating afterwards, oxygen supply step.
Can check oxygen pressure and the system works situation of whole system in this way fast, effectively, accurately, operating process is simple, method is reliable.
