The hydraulic work process:
By second throttle valve 42, the second unidirectional electrical magnet valve 41 enters the cavity of resorption of oil cylinder 33, after pressure oil enters the oil cylinder cavity of resorption, the fluid of oil cylinder epicoele is discharged, the pressure oil effect promotes piston and moves up, and oil cylinder begins action one-way valve effect when oil cylinder epicoele fluid pipeline will be by the automatically controlled first unidirectional electrical magnet valve 32, when fluid can not pass through, because oil cylinder epicoele fluid can not be discharged, oil cylinder 33 all is failure to actuate.
When the first unidirectional electrical magnet valve 32 respectively electric after electric control one-way valve open, oil cylinder epicoele fluid is by the automatically controlled first unidirectional electrical magnet valve 32, first throttle valve 31 is gone into fuel tank 30 times by two-position four way change valve.When the automatically controlled first unidirectional electrical magnet valve 32 respectively during electric opening, corresponding oil cylinder epicoele fluid is discharged the oil cylinder piston cylinder action that moves up.
When the 3rd unidirectional electrical magnet valve 34 when electric, one-way valve opens oil circuit pressure oil is by the 3rd unidirectional electrical magnet valve 34, promoting two-position four way change valve 30 spools moves to left, pressure oil enters into oil circuit by oil circuit to two-position four way change valve 30 and enters oil cylinder 33 epicoeles by the first throttle valve 31 automatically controlled first unidirectional electrical magnet valve, 32 oil circuits, when same oil cylinder 33 cavity of resorption fluid will be by the automatically controlled second unidirectional electrical magnet valve 41 one-way valve effect fluid can not by the time oil cylinder 33 be failure to actuate.
When the second unidirectional electrical magnet valve 41 open after when electric, oil cylinder cavity of resorption fluid by the second unidirectional electrical magnet valve 41, second throttle valve 42 to oil circuit, and by two-position four way change valve 30 oil sump tanks.When the second unidirectional electrical magnet valve 41 got electric opening, corresponding oil cylinder cavity of resorption fluid was discharged, and oil cylinder upper cavity pressure oil apply piston moves down oil cylinder and begins action.
The concrete working principle of combined type multi-way reversing solenoid valve:
As shown in Figure 2, high pressure oil by Fig. 3 channel B 12, enters the B chamber 23 of Fig. 2, inlet passage E17 from filler opening 25.Fig. 5 passage E17 pressure oil enters H1 chamber 40 by throttle valve second adjusting screw 16, pressure oil enters first nonreturn valve core 9, enter I chamber 38 to oil cylinder cavity of resorption interface 39, the promotion oil cylinder piston moves up, oil cylinder epicoele fluid enters I1 chamber 26 by oil cylinder epicoele interface 27, pressure oil can not be discharged when second nonreturn valve core 10 was closed, oil cylinder is failure to actuate, pressure oil enters H chamber 28 by second nonreturn valve core 10 when 10 energisings of second nonreturn valve core are opened, by throttle valve first adjusting screw 13 inlet passage F20, C14 returns into fuel tank by drainback passage.Pressure oil advances from filler opening 25 like this, and oil return is returned out from drainback passage C14, and oil cylinder moves up.
Shown in Figure 3, the 3rd nonreturn valve core 1 gets electric opening, pressure oil enters from channel B 12, passage G35 and passage H36, because of the passage D15 in the middle of the changeover valve core among Fig. 36 communicates with passage D15, drainback passage C14 among Fig. 2, so steel ball 4 left sides and changeover valve core 6 left side pressure are little, when passage H36 enters pressure oil, compressing steel ball 4 compresses at R place 37 with changeover valve core 6, promoting changeover valve core 6 is moved to the left, B chamber 23 communicates with passage F20 among Fig. 6, and pressure oil enters Fig. 5 passage F, and Fig. 6 passage E17 returns into fuel tank by drainback passage C14; Because the second unidirectional electrical magnet valve 41 is identical with the first unidirectional electrical magnet valve, 32 symmetries, so opening oil cylinder when the second unidirectional electrical magnet valve 41 descends, when the second unidirectional electrical magnet valve 41 close the hydraulic circuit oil return close oil cylinder stop the action, when two-position four-way solenoid valve 30 outages, the 3rd nonreturn valve core 1 closure, pressure oil fragmentary 3 changeover valve cores 6 the right of passage G35 and passage H36 do not have pressure oil among Fig. 4, first spring 5 is pushed steel ball 4 open and is moved to right among Fig. 6, second spring, 7 effects simultaneously, changeover valve core 6 moves right among Fig. 3, the fluid in C chamber 24 enters chamber, a changeover valve core left side by R place 37 among Fig. 4 among Fig. 6, and the changeover valve core 6 of Fig. 3 resets to the right.
Embodiment 2, and as shown in Figure 7, as can be seen as long as add that in oil circuit a pair of electric control one-way valve just equals to increase a 3-position 4-way solenoid directional control valve, volume is little, and is easy for installation from schematic diagram.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
