Description
Technical field
The invention belongs to aircraft support measuring technologies, are related to a kind of equipment that can detecte aircraft oxygen system performance.
Technical background
The offering oxygen way of service aircraft oxygen system is " oxygen supply of lung formula ", and feature is to need actively to inhale just from oxygen outlet
It can supply, not inhale, stop supplying, that is, need aspiratory action and the effective trigger condition of oxygen supply valve generation (is reached certain to bear
Pressure) can just there be oxygen output, so the test equipments such as simple flowmeter, differential manometer are unable to test the type aircraft oxygen system
It supplies oxygen performance (such as inspiratory resistance, oxygen delivery capacity, system low-voltage section negative pressure air-tightness).Realize test the type aircraft oxygen
System supplies oxygen the test of performance, other than needing the measuring instruments such as flowmeter, differential manometer, it is also necessary to active inspiration device.
Summary of the invention
The purpose of the present invention is: based on the high-pressure air source by belt switch pressure reducing valve, it is integrated with flowmeter, differential manometer, vacuum
The integrated test system of portable device and the connecting line composition of injector, realizes " oxygen supply of lung formula " aircraft oxygen system
Supply oxygen in-situ test on the machine of performance (such as " inspiratory resistance ", " oxygen delivery capacity " and " negative pressure air-tightness ").
A kind of technical solution of the present invention: equipment can detecte aircraft oxygen system performance, which is characterized in that belt switch
The high-speed flow that the high-pressure air source 3 of pressure reducing valve provides sprays after the entrance of injector 4 through outlet, at the injection end of injector 4
Corresponding negative pressure is formed, after the injection end series connection orifice-plate type differential pressure flowmeter 5 and differential manometer 1 of injector 4, is connected to tested fly
The outlet of machine oxygen system is realized and measures inspiration flow value and intake negative-pressure value again while exporting and oxygen is sucked out from oxygen system.
The high-pressure air source 3 of the belt switch pressure reducing valve is equipped with switch pressure reducing valve, can by the aperture of regulating switch pressure reducing valve
To control inspiratory airflow size.
The orifice-plate type differential pressure flowmeter 5 is equipped with pressure difference transmitter 2, for measuring inspiration flow value.
Increase differential manometer 1 between the orifice-plate type differential pressure flowmeter 5 and tested aircraft oxygen system outlet, is inhaled for measuring
Gas negative pressure value.
The invention has the advantages that being integrated with flowmeter, differential manometer, vacuum based on the high-pressure air source by belt switch pressure reducing valve
The integrated test system of portable device and the connecting line composition of injector, realizes " oxygen supply of lung formula " aircraft oxygen system
In-situ test on the machine of performance (such as " inspiratory resistance ", " oxygen delivery capacity " and " negative pressure air-tightness ") is supplied oxygen, it is highly integrated, just
Take it is light, it is easy to operate；Intake negative-pressure can actively be generated and reach larger inspiratory flow and synchronism detection flow value and negative pressure value.
Detailed description of the invention
Fig. 1 is the working principle of the invention figure
Fig. 2 is schematic diagram under working condition of the present invention
Specific embodiment
The present invention is described in further details with reference to the accompanying drawing: referring to Fig. 1, Fig. 2, by the high pressure of belt switch pressure reducing valve
The high-speed flow that gas source 3 provides sprays after the entrance of injector 4 through outlet, to form corresponding negative pressure at injection end.It will draw
After penetrating end series connection orifice-plate type differential pressure flowmeter 5 and differential manometer 1, it is connected to tested aircraft oxygen system outlet, is thus realized
Inspiration flow value and intake negative-pressure value (i.e. " inspiratory resistance ", " confession have been measured while exporting and oxygen is sucked out from oxygen system again
Oxygen ability " and " negative pressure air-tightness " etc.).The high-pressure air source 3 of belt switch pressure reducing valve is equipped with switch pressure reducing valve, passes through regulating switch
The aperture of pressure reducing valve can control inspiratory airflow size, and inspiration flow value can be by concatenated orifice-plate type differential pressure flowmeter 5
Pressure difference transmitter 2 convert after read, the intake negative-pressure value under the corresponding flow can be read by differential manometer 1.
