Can be seen that several common from above 5 examples, one is that gas exhaust inspecting pressure switch 7 is arranged on waste gas
In backflow gas circuit, using the pressure of waste gas, control the unlatching of air bleeding valve 2 by gas exhaust inspecting pressure switch 7；Two is choke valve peace
It is contained in exhaust gas recirculation gas circuit, and the exhaust gas recirculation back segment in gas exhaust inspecting pressure switch 7；Three is if choke valve is arranged on
Supply, exhaust gas recirculation share to be needed during gas circuit section to use the exhaust gas recirculation throttling one-way valve 8 with reverse throttle orifice.
The operation principle of each embodiment of this utility model is：When air pump 1 operates, by the compression within air pump 1, make sky
Atmospheric pressure increases outflow air pump, carries out moisture filter, moisture is stayed in exsiccator 3 inside exsiccator 3, and the compression being dried is empty
Air-flow is through supply check valve 4, then supplies gas receiver and with device of air using dried compressed air by supplying delivery outlet；Gas
The pressure of pump control pressure switch 5 detection supply delivery outlet, when pressure reaches the pressure of setting, supply control pressure switch 5
Contact disconnect, the power supply of cut-out automotive relay coil, the main contacts of relay disconnects, and so that air pump 1 is stopped power supply operating, and
Power supply is switched to the coil power end of air bleeding valve 2 by auxiliary contact；The coil of air bleeding valve 2 passes through gas exhaust inspecting pressure switch 7
It is exhausted control, to have waste gas to enter fashionable when connecting altitude valve waste discharge QI KOU, and gas exhaust inspecting pressure switch 7 measures this point
When pressure is higher than setting value, contacting, the coil of air bleeding valve 2 obtains electric current makes air bleeding valve 2 open, and waste gas flows through waste gas reuse
Check valve 6 and choke valve enter exsiccator 3, then are discharged by air bleeding valve 2, while waste gas is discharged, also take away in exsiccator
Moisture, makes exsiccator recover desiccation.
The effect of exhaust gas recirculation throttling one-way valve 8 is：When air pump works, compressed air is returned through waste gas from exsiccator 3
During stream throttling one-way valve 8 flow direction supply delivery outlet, this valve is opened entirely, realizes big air-flow output；When having waste gas from exhaust gas recirculation list
To valve 6 flow back to exsiccator 3 when, exhaust gas recirculation throttling one-way valve 8 close heavy caliber flow mouth retain osculum run-off mouth, have this section
The restriction of stream valve, is avoided that ' when air bleeding valve 2 is opened, the pressure of exhaust gas recirculation gas circuit can reduce quickly, reaches gas exhaust inspecting
The opening pressure of pressure switch 7, sets up pressure because waste gas does not also have enough time to be back in exhaust gas recirculation gas circuit, and air bleeding valve 2 is in row
Will close quickly under the control of gas control pressing pressure switch 7, when waste gas continues to be back in exhaust gas recirculation gas circuit, make exhaust gas recirculation
Pressure in gas circuit rises to the initiation value of gas exhaust inspecting pressure switch 7, and air bleeding valve 2 is opened again, discharges dry exhaust gas recirculation gas
Compressed air inside road, so, air bleeding valve arises that the phenomenon discontinuously switching on and off.By the work throttling with choke valve
With making the pressure at normally opened gas exhaust inspecting pressure switch 7 slowly be discharged, allowing its pressure slowly to reduce, it is to avoid air bleeding valve 2 is frequent
Startup and disconnect this phenomenon generation.
