Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Fig. 1 to 5, the utility model fork truck gearshift solenoid valve, the switch of fork truck gearshift, be arranged in cab mechanism, comprise valve seat 1, spool 2, base 3, zero type circle 4, dynamic iron core 5, nut 6, static iron core 7, magnetism resistent ring 8, coil 9, spring 10 and damper 11 form, wherein base 3, static iron core 7, magnetism resistent ring 8 is welded as a whole by laser bonding and argon arc welding, form sleeve pipe 12, zero type circle 4 is arranged on sleeve pipe 12, help to improve seal action, the integrated molding and forming of coil 9, coil 9 overlaps on sleeve pipe 12 after welding, nut 6 can match with the screw thread on sleeve pipe 12, coil 9 is fixed on the base 3 of gearshift solenoid valve.
Dynamic iron core 5 designs one end in external form and is designed to taper, matches, can compress contact when dynamic iron core 5 moves with static iron core 7 with the conical socket structure of static iron core 7; The other end of dynamic iron core 5 adopts T-slot shape structure, in mating connection with the T-shaped projection in the front end of spool 2; Dynamic iron core 5 adopts via cavities body structure, through hole cavity is designed to step-like column construction, spring is provided with in the cavity that cone structure side diameter is large, the cavity internal fixtion little at T-slot shape structure side diameter is provided with damper 11, damper 11 is hollow annular construction, fixes and can adopt modes such as pressing.
During installation, spool 2 is placed in the inner chamber of valve seat 1, spool 2 is set to the step-like structure with 30 ° ~ 80 ° of angles compared with its tail end of conventional construction, and valve seat 1 is designed to U-shape, and spool 2 is fixed by side, and it is in mating connection that opposite side and sleeve pipe 12 pass through screw thread.
Below the oil circuit of gearshift solenoid valve to be arranged and working state is sketched: when coil no electric circuit, 3. 1. actuator port communicate with return opening, and filler opening is 2. 1. 3. all obstructed with return opening with actuator port, in closed condition; Dynamic valve pocket between iron core with static iron core also with 3. communicates, in unloading condition; When the coil is energized, the magnetic induction force that coil produces drives dynamic iron core 5 to the motion of coil 9 direction, and is with movable valve plug 2 to the motion of coil 9 direction, and 3. actuator port cuts out, and 2. filler opening communicates with 1. actuator port, is electro-hydraulic control valve fuel feeding; Now because dynamic iron core 5 moves to coil 9 direction, dynamic iron core 5 progressively diminishes with static iron core 7 valve pocket, its internal hydraulic pressure oil is due to the damping function of damping hole, its valve pocket pressure is increased, slow down the speed that dynamic iron core moves to coil direction, reduce spool opening speed, thus decrease the hydraulic shock of spool unlatching; When the coil is de-energized, under spring force, dynamic iron core 5 moves to valve seat 1 direction with spool 2, working oil hydraulic pressure enters dynamic iron core 5 and static iron core 7 valve pocket by damping hole, due to the damping function of damping hole, extend the pressure time in valve pocket, thus reach the effect of spool slowly closing, and decrease hydraulic shock when spool is closed.
Although give detailed description and explanation to embodiment of the present utility model above; but what should indicate is; we can carry out various equivalence according to conception of the present utility model to above-mentioned mode of execution and change and amendment; its function produced do not exceed that Figure of description contains yet spiritual time, all should within protection domain of the present utility model.
