Hereinafter, fork truck special oil in the present embodiment, which is described in detail, in cooperation attached drawing 1 presses solenoid directional control valve working method.
Fork truck special oil pressure solenoid directional control valve working method be：It seals power supply and connects 25 external 220V AC powers of box,
Solenoid directional control valve is pressed to provide power supply for fork truck special oil；When fork truck special oil pressure solenoid directional control valve is not powered on, during spool 12 is in
In chambers of the heart body 111, resetting spring 13 is in nature uncompressed state；When the one of which cable in sealing power supply connection box 25 connects
When energization source, for power supply by coil 22, there is electromagnetic induction in coil 22, generates thrust, and thrust pushes magnet assembly cavity 26
Interior electromagnet 23 is moved towards 14 one end of end cap, and electromagnet 23 drives push rod 28 to be moved towards 13 direction of resetting spring, resetting spring
13 push spool 12 to be moved towards 14 one end of end cap, at this point, resetting spring 13 is in compressive state；Fork truck special oil presses electromagnetic switch
After valve power-off, the thrust that coil 22 generates disappears, at this point, resetting spring 13 will restore nature uncompressed state, resetting spring 13
The elastic force of generation drives push rod 28 to restPose.When the another set cable in sealing power supply connection box 25 powers on
When, for power supply by coil 22, there is electromagnetic induction in coil 22, generates pulling force, and pulling force pulls the electricity in magnet assembly cavity 26
Magnet 23 is moved towards the direction far from end cap 14, and electromagnet 23 is by connecting pin 123 with movable valve plug 12 to far from end cap 14
One end is moved, at this point, resetting spring 13 is in compressive state；After fork truck special oil presses solenoid directional control valve power-off, coil 22 generates
Pulling force disappear, at this point, resetting spring 13 will restore nature uncompressed state, the elastic band movable valve plug 12 that resetting spring 13 generates
It restPoses.Fork truck special oil presses the shifting of solenoid directional control valve control spool 12 by controlling two groups of cables and being separately energized
Dynamic direction.
The original state of oil inlet cavity P is that oil inlet cavity P is constantly in into oil condition, when in sealing power supply connection box 25
One group of cable energization back valve core 12 moves to the left, and oil inlet cavity P is connected to fuel-displaced cavity A, at this time fuel-displaced cavity B and oil return
Cavity T-phase connects；And seal power supply connection box 25 in another group of cable be powered after, spool 12 moves to the right, oil inlet cavity P with
Fuel-displaced cavity B connections, fuel-displaced cavity A and oil return cavity T-phase company, fork truck special oil press solenoid directional control valve by controlling two groups at this time
Cable is separately energized and then controls hydraulic oil to flow out from different fuel-displaced cavitys.
The fork truck special oil of the utility model presses solenoid directional control valve, realizes solenoid valve volume-diminished, it is close to improve lamp cap
The disadvantage of envelope property difference, can be widely applied in the engineering trucks such as fork truck field.
The embodiment of upper described only the utility model, is not intended to limit the utility model.For this field
For technical staff, various modifications and changes may be made to the present invention.The interior institute of all spirit and principle in the utility model
