Fluid enters main valve body 500 from main valve body filler opening A, and by the waist shaped hole 05 of main valve housing 400 and the radial hole 06 of main valve plug 300, the oil outlet 08 through going out on the oil jacket 600 flows out to main valve body oil outlet B.Because the oil outlet 08 that goes out on the oil jacket 600 is connected with load in the oil-way system, so produce a working pressure in the fluid, this pressure promotes main valve plug 300 and up moves, when control oil is not transfused in the control oil channel 14, main valve plug 300 is moved to goes up the place most, waist shaped hole 05 and radial hole 06 are hidden mutually, and valve is closed, and oil circuit disconnects; When importing the pilot pressure oil from control port 15, by the control oil channel on the main valve body 500 14, control oil channel hole 10 and damper 09, fluid enters 01 pair of main valve plug of main valve plug epicoele 300 and produces a downward thrust, main valve plug 300 is moved down,, between waist shaped hole 05 and radial hole 06, form different extended distance X according to the size of pilot pressure, therefore when induced pressure one timing, pilot pressure is big more, and extended distance X is also just big more, and flow is also just big more.When adopting body control, the adjustment sleeve 59 on the adjusting relief valve plug-in unit 700 can change the size of pilot pressure.
When load changes, the pressure at oil outlet 08 place is instantaneous also will to change, when instantaneous the diminishing of pressure at oil outlet 08 place, main valve plug 300 will disequilibrium have the tendency that moves down, simultaneously because the effect of damper 19, the two ends of the spool 37 in pressure compensation plug-in unit 800 produce a pressure reduction, make spool 37 in the pressure compensation plug-in unit 800 to spring 34 side shiftings, hole 1 in the pressure compensation plug-in unit 800 is communicated with hole 2 17, pilot pressure descends rapidly, and with the induced pressure transient equilibrium, the pressure of main valve plug epicoele 01 also reduces rapidly, make extended distance X keep constant, flow does not change; When the instantaneous rising of pressure at oil outlet 08 place, on having, main valve plug 300 disequilibriums move tendency, extended distance X reduces, main valve plug epicoele 01 pressure is raise rapidly, because the effect of damper 09, make the main valve plug pressure at two ends reach balance rapidly, make extended distance X remain unchanged, it is constant that flow keeps.
The function of relief valve plug-in unit 700 has two: the one, regulate pilot pressure according to different loading conditions, with the output of the diverse location between change main valve plug 300 and the main valve housing 400 with the acquisition different flow; The 2nd, when control oil adopts far-end control, make safety valve and use.
By the pressure gauge of on cover plate 100, installing 900, the size that can observe pilot pressure at any time.Simultaneously the outlet valve of installing on cover plate 100 200 can be removed the air in the main valve plug epicoele 01 effectively, reduces to utter long and high-pitched sounds and the shake of main valve plug 300.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
