The entrance point connection of second check valve；First check valve, the second check valve with plus/unloading magnetic valve the port of export connect and
It is connected respectively with circulating control mouth P1, the control mouth of intake valve and the inlet end of adjustable throttling of unloading valve；The shutdown
The control mouth of atmospheric valve and the internal interface a connections of intake valve；The inlet end for shutting down atmospheric valve and circulation unloading valve enter
It is connected after the connection of gas end with the control mouth of gs-oil separator；The outlet side of the circulation unloading valve is connected to air inlet by choke valve
At the internal interface b of valve.
Preferably, described plus/unloading magnetic valve and high low pressure magnetic valve are all normally closed solenoid valve.
Due to being had the following advantages that using such scheme, the utility model：
1. startup is light-load starting, avoids starting load excessive, do not prevented the situation of machine；
2. under unloaded state, system inner loop under a lower pressure is run, and energy-conserving and environment-protective, prevents machine
Hair gives birth to surge phenomenon；
3. system working pressure sets two grades of height, set up by user's request.
In summary, air inlet control program of the present utility model, it is possible to achieve the light-load starting of air compressor machine, maintain air compressor machine
System keeps low-pressure interior to circulate under unloaded state, possesses two grades of system working pressures, these functions can overcome air compressor machine
Difficulty in starting, ensure air compressor machine energy-saving run under unloaded state, and the high/low work of the job requirements initialization system according to client
Make pressure.

Embodiment
As shown in figure 1, the compressed air of gs-oil separator is passed through into filter 6, it is connected to plus/unloading magnetic valve 3, high/low
Pressure electromagnetic valve 5 and the inlet end of high-pressure regulating valve 4；The outlet of high low pressure magnetic valve 5 is terminated with low pressure regulating valve 7；
It is all normally closed solenoid valve to add/unload magnetic valve 3 and high low pressure magnetic valve 5, and the outlet side of high low pressure magnetic valve 5 connects first
Check valve 81, the outlet side of high-pressure regulating valve 4 connect the second check valve 82；First check valve 81, the second check valve 82 with
Add/unload the port of export connection of magnetic valve 3 and the respectively control mouth and adjustable throttling 9 with circulation unloading valve 2, intake valve 10
Inlet end connection；Shutdown atmospheric valve 1 is normally closed type valve, shuts down the control mouth of atmospheric valve 1 and connects with the internal interface a of intake valve 10
Connect；The inlet end for shutting down atmospheric valve 1 and the inlet end for circulating unloading valve 2 are connected after connecting with the control mouth of gs-oil separator；Follow
The outlet side of ring unloading valve 2 is connected at the internal interface b of intake valve 10 by choke valve 11.
When air compressor machine starts, add/unload magnetic valve 3 must be electrically connected, intake valve 10 is opened in the presence of vacuum, system
Pressure rises, and control gas passes through filter 6 by adding/unloading magnetic valve 3, into the circulation control mouth P1 of unloading valve 2, by its dozen
Open, the compressed air in gs-oil separator is discharged into by choke valve 11 in intake valve 10, form inner loop；In addition all the way
Into the control mouth of intake valve 10, valve port opening is turned down；By adjusting the restriction size of adjustable throttling 9, system pressure is adjusted
