The second oil-in 42 that oil circuit reaches temperature-sensing valve 4 is propped up, another oil circuit reaches the first of temperature-sensing valve 4 Jing after the cooling of oil cooler 3
Oil-in 41.There is temperature-sensing element 44 in temperature-sensing valve 4, can be according to the dynamic of the temperature range of the setting control inner spool 45 of temperature-sensing valve 4
Make, so as to change the connected relation between the oil-in 41 of temperature-sensing valve 4 first, the second oil-in 42, oil-out, i.e., when air compressor machine is firm
During start, than relatively low, the second oil-in 42 of temperature-sensing valve 4 is connected with oil-out, and the first oil-in 41 is closed for the temperature of lubricating oil,
Incorporated by reference to Fig. 2.With the prolongation of run time, the temperature of lubricating oil steeply rises, when the temperature of lubricating oil is reached in temperature-sensing valve 4
During the lower limit of the design temperature scope of temperature-sensing element 44, the first oil-in 41 of temperature-sensing valve 4 is gradually connected with oil-out, the second oil-feed
Mouth 42 is progressively closed off, incorporated by reference to Fig. 4；When the temperature of lubricating oil is higher than the upper of the design temperature scope of temperature-sensing element 44 in temperature-sensing valve 4
In limited time, the first oil-in 41 of temperature-sensing valve 4 is connected completely with oil-out, and the second oil-in 42 is completely closed, incorporated by reference to Fig. 5.
I.e. when air compressor machine reaches normal operation through start process, from the lubricating oil that temperature-sensing valve oil-out 43 flows out
Only two kinds situations：(1) temperature of lubricating oil is then to enter from second in the range of the design temperature of temperature-sensing element 44 in temperature-sensing valve 4
Lubricating oil that the part that hydraulic fluid port 42 comes is cooled down without oil cooler 3 and the part come from the first oil-in 41 are passed through
The lubricating oil that the lubricating oil of the cooling of oil cooler 3 is mixed；(2) because the temperature of lubricating oil is higher and higher than in temperature-sensing valve 4
The design temperature range limit of temperature-sensing element 44, the first oil-in 41 for making temperature-sensing valve 4 is connected completely with oil-out, the second oil-in
42 completely close, then the lubricating oil through the cooling of oil cooler 3 for only coming from the first oil-in 41.Above-mentioned situation can be protected
It is higher than the design temperature range lower limit of temperature-sensing element 44 in temperature-sensing valve 4 to demonstrate,prove the lubricating oil temperature flowed out from temperature-sensing valve oil-out 43, from
And prevent the precipitation of condensed water in compressed air during one stage of compression process and cascade EDFA.Last lubricating oil is through oil strainer
Clear device flows through threeway and respectively enters jet 12 between one-level jet 11 and level after filtering, and plays cooling, lubrication, sealing and noise reduction
Effect.
In the utility model, first oil-in 41 and the second oil-in 42 of temperature-sensing valve 4 connect respectively oil cooler 3 and oil
Gas separating device 2, controls valve element 45 and moves, so as to control the first oil-in 41 and the second oil-in by the interior temperature-sensing element 44 for setting
42 open or close, and so as to be controlled to the oil temperature for exporting, prevent that the oil temperature for exporting is too low, and too low oil temperature can cause air pressure
There is condensed water to separate out in compression process.
The utility model preferred embodiment is these are only, embodiment of the present utility model and protection is not thereby limited
Scope, to those skilled in the art, should can appreciate that all utilization the utility model specifications and diagramatic content institute
Scheme obtained by the equivalent made and obvious change, should be included in protection domain of the present utility model
It is interior.
