6-15 enters oil pressure cylinder 15 and is pressurized, and carries out pressurize processing after reaching the pressure value of pressure sensor 6-16 settings, protects
After the pressure time arrives, starts the b heads of two 6-2 of solenoid directional control valve and P is made to lead to B, the high pressure liquid pressure oil of pump one 8-1 outputs is overflow from superposing type
Outflow starts the b heads of four 6-4 of solenoid directional control valve and P is made to lead to B, duplex to make oil piping system be in low pressure at one 6-18 of stream valve
The hydraulic oil of pump one 8-1 conveyings in pump 8 passes through the holes B of two 6-8 of stacked unidirectional valve and pries open the holes A, so that rising oil
Hydraulic oil in 14 middle cylinder of cylinder from the holes the T oil return to fuel tank 1 of four 6-4 of solenoid directional control valve, meanwhile, start solenoid directional control valve five 6-
5 a heads simultaneously make P lead to B, and the hydraulic oil of the pump one 8-1 conveyings in duplex pump 8 passes through the holes B of three 6-9 of stacked unidirectional valve and pries open
The holes A, so that the hydraulic oil in 15 middle cylinder of oil pressure cylinder is from the holes the T oil return to fuel tank 1 of five 6-5 of solenoid directional control valve and makes
15 pressure of oil pressure cylinder declines, and a heads of one 6-1 of Time Delay Opening solenoid directional control valve simultaneously so that (Time Delay Opening electromagnetism changes the logical B of P here
To the purpose of a heads of one 6-1 of valve：Pressure crosses conference and causes hydraulic control prefill valve that can not open, allow to open in oil piping system,
The case where also due to oil piping system pressure is excessive and generating sonic boom, so needing Time Delay Opening hydraulic control prefill valve 16, makes oil circuit
The case where sonic boom is generated when the pressure of system further decreases to avoid hydraulic control prefill valve 16 that from can not opening or open), duplex pump 8
The hydraulic oil of pump one 8-1 conveying the holes B are entered by the holes P and pry open hydraulic control prefill valve 16 so that workbench 18 and pressure oil
15 rapid decrease of cylinder, when workbench 18 drops to, the when of soon returning in situ, at this moment workbench 18 can touch limit switch 20,
At this moment, position in giving signal and four 6-4 of solenoid directional control valve being made to return starts a heads of three 6-3 of solenoid directional control valve and P is made to lead to B, from
And so that the hydraulic oil of pump one 8-1 conveyings passes through the holes B of one 6-7 of stacked unidirectional valve and pries open the holes A, so that upper oil-lifting jar
Hydraulic oil in 14 is flowed back by the holes T of three 6-3 of solenoid directional control valve in fuel tank 1, due to the holes the T hole of three 6-3 of solenoid directional control valve
Diameter is significantly smaller than the holes the T aperture of four 6-4 of solenoid directional control valve, so upper oil-lifting jar 4 can slow down and stop that oil pressure cylinder 15 subtracts
Speed is lowered back to original position, so can to avoid 15 returning quickly of oil pressure cylinder and caused by the too fast generation of 15 return of oil pressure cylinder it is huge
The case where ringing, oil pressure cylinder 15 avoided to damage；Here the effect of Superimposed relief valve 6-18 is the low-pressure in holding system,
For prying open the pilot operated valve device in each the utility model, so that in the case that system is without keeping high pressure to run, it will be able to
Each pilot operated valve device is pried open, in the case of there is no Superimposed relief valve in system, in order to make there is enough pressure to pry open in system
Pilot operated valve device in the utility model can only increase system pressure, using being used for control system maximum pressure in oil piping system
Overflow valve 6-19 controls the pressure in whole system and guarantees to pry open each pilot operated valve device, however in prolonged system
Big pressure must utilize motor overload to run, energy saving to be unfavorable for；Here the effect of electric-hydraulic control reversing valve is, for flowing greatly
It measures, in the oil piping system of high pressure, since excessive flow and pressure can make solenoid directional control valve can not normal operation.
Although the utility model is shown and described by reference to preferred embodiment, this profession is common
Technical staff can make various variation in form and details it is to be appreciated that in the range of claims.
