Specific embodiment
Present invention will be described in further detail below with reference to the accompanying drawings.
Referring to Fig. 1, turbine oil steady pressure of system adjuster of the invention passes through the fixed spiral shell 7 of first flange and the second method
Flange 1 and shell 9 are fixed together by blue fixing screws 8.The left end of bellows 10 and upper left end housing 9.3 and lower-left end housing
9.4 weld together, and the right end and upper right end housing 9.1 and bottom right end housing 9.2 of bellows 10 weld together, valve 11 and hollow
Column 19 welds together.The left end of compressor air chamber spring 12 heads at valve 11, and right end, which heads into, adjusts screw 20, lubricating oil
The left end of disengagement chamber spring 4 heads into upper left end housing 9.3 and lower-left end housing 9.4, and the right end of lubricating oil disengagement chamber spring 4 heads into valve
At 11.Valve rod 5 penetrates into and withstands valve 11 by the hole of 9 left end of shell, and is fixed by fixture nut 29 in outside.First
Joint protective cap 2 is mounted on the first connector 68, valve rod protective cap 3 is mounted on the top of valve rod 5, the second joint protective cap 6 peace
On the second connector 66, it is used to prevent foul from entering in shell 9.Lower-left end housing 9.4 and 9.3 left end of upper left end housing have
Gas mixture D from lubricating oil separator box is passed through lubricating oil disengagement chamber cavity G, is formed outside shell 9 and bellows 10 by one hole
Lubricating oil disengagement chamber cavity G, 10 inside of bellows and shell 9 form low-pressure compressor air cavity F.
Working principle of the present invention is as follows:
The oil gas for being able to maintain the air C static pressure for being passed through low-pressure compressor through the invention and being passed through static oil-gas separator
The difference of pressure in mixture E is stablized.The air C for being passed through low-pressure compressor is filled with low-pressure compressor air by the second connector 66
Cavity F, the gas mixture in gs-oil separator feeds the cavity of lubricating oil disengagement chamber by the first connector 68, logical using valve rod
Road is discharged into static oil-gas separator.When the gas mixture D pressure rise from lubricating oil separator box, valve 11 moves right,
Gap B between valve stem end and valve increases, and the gas mixture D from lubricating oil separator box is excluded from the by-pass prot of valve rod 5, makes
The pressure reduction of lubricating oil disengagement chamber cavity G.When the gas mixture D from lubricating oil separator box is reduced, valve 11 is moved to the left, valve
Gap B between boom end and valve reduces, this leads to the pressure rise of lubricating oil disengagement chamber cavity G.Pressure in gs-oil separator
Adjusting is to change its gap B with valve 11 by adjusting nut 25 to realize.
The foregoing is merely presently preferred embodiments of the present invention, rather than carries out restriction in any form, ability to the present invention
It should be understood that under conditions of not departing from spirit of that invention and principle, the present invention can also carry out several field technique personnel
Simple modification and replacement, these modifications and replacement similarly fall into the protection scope delimited by submitted claims it
It is interior.
