This solenoid valve is normally open solenoid valve, and its working procedure is as follows:
When this solenoid valve obtains when electric, solenoid valve touches moment, the coil of described electromagnet 6 passes to larger electric current, described electromagnet 6 just produces enough large electromagnetic force, under the effect of electromagnetic force, described armature 7 drives described outer spool 3 to overcome hydraulic coupling and mechanical resistance rapidly to left movement, until the left sealing cone 4a of its left fitted seal conical surface 2b1 and left inside spool 4 fits tightly; Meanwhile, the right fitted seal conical surface 2b2 of described outer spool 3 separates (referring to Fig. 1 and Fig. 2) with the right sealing cone 5a of described right inside spool 5; Subsequently, the coil of described electromagnet 6 just passes into less stabling current, maintains certain electromagnetic force, to keep the left fitted seal conical surface 2b1 of described outer spool 3 and the left sealing cone 4a of left inside spool 4 to fit tightly, thereby this solenoid valve is kept closed.Now, described filler opening 8 is sealed by left fitted seal conical surface 2b1 and left sealing cone 4a, described return opening 9 and control drain tap 10 and be communicated with control unit oil return, this process implementation the quick closedown of solenoid valve;
In the time of this solenoid valve dead electricity, electromagnetic force disappears, because the oil pressure of described filler opening 8 is larger, and the area towards the second through hole 2b mono-side of described oil inlet hole 3a is greater than the area of the second through hole 2b mono-side dorsad (compression area that is oil inlet hole 3a left side is less than right side) of oil inlet hole 3a, so the high pressure liquid force feed in described oil inlet hole 3a can produce very large action of hydraulic force to the right by external spool 3, drive described outer spool 3 to move to right-hand member fast, until the right sealing cone 5a of its right fitted seal conical surface 2b2 and described right inside spool 5 fits tightly; In the time that high pressure liquid force feed is full of whole valve pocket, this high pressure liquid force feed can produce hydraulic coupling left to the step surface of described the second through hole 2b and fourth hole 2d junction, this hydraulic coupling can reduce stressed between right fitted seal conical surface 2b2 and right sealing cone 5a effectively, to improve working life; Meanwhile, the left fitted seal conical surface 2b1 of described outer spool 3 separates (referring to Fig. 1 and Fig. 2) with the left sealing cone 4a of described left inside spool 4; Now, described return opening 8 is sealed by described right fitted seal conical surface 2b2 and right sealing cone 5a, described filler opening 8 and control drain tap 10 and be communicated with, this process implementation the quick unlatching of solenoid valve.
The present invention is by adopting the technological scheme that the diameter of the stub end of left fitted seal conical surface 2b1 is designed to the diameter of the stub end that is less than left sealing cone 4a, while making left sealing cone 4a and left fitted seal conical surface 2b1 gluing, sealing, the area towards the second through hole 2b mono-side of oil inlet hole 3a is greater than the area of the second through hole 2b mono-side dorsad of oil inlet hole 3a, and then to make the external spool 3 of high pressure oil in oil inlet hole 3a produce (in Fig. 2 to the right) thrust be reposition force, like this, in the time of electromagnet 6 dead electricity, just can realize automatically reseting of outer spool 3 by this reposition force; Because the pressure of the high pressure oil in described oil inlet hole 3a is certain, so described reposition force is definite value, thereby improve the control accuracy of this solenoid valve; Meanwhile, because the pressure of the high pressure oil in oil inlet hole 3a is very large, so the high pressure oil in oil inlet hole 3a can produce very large reposition force by external spool 3, like this, in the time of electromagnet 6 dead electricity, the outer spool 3 of described reposition force energy fast driving resets, and has improved the speed of response of this solenoid valve;
By add fourth hole 2d in the second through hole 2b, make the junction of the second through hole 2b and fourth hole 2d form step surface, like this, high pressure oil in outer spool 3 just can to described step surface outer spool 3 produce (in Fig. 1 left) thrust, this thrust just can be offset the reposition force of the external spool 3 of a part of high pressure oil, thereby reduce the adhesive force between described right fitted seal conical surface 2b2 and right sealing cone 5a, improve the working life of outer spool 3 and right inside spool 5, and then the working life of having improved this solenoid valve;
By adopting the technological scheme that the diameter of the stub end of right fitted seal conical surface 2b2 is designed to the diameter of the stub end that is less than described right sealing cone 5a, while making right fitted seal conical surface 2b2 and right sealing cone 5a gluing, sealing, the area towards the second through hole 2b mono-side of spill port 3b is greater than the area of the second through hole 2b mono-side dorsad of spill port 3b, and then make the external spool 3 of high pressure oil in spill port 3b produce (in Fig. 2 left) thrust, this thrust can be offset the reposition force of the external spool 3 of a part of high pressure oil further, thereby improve further the working life of this solenoid valve,
The mode fixed electromagnet 6 press-fiting by employing, this means of fixation can prevent that described electromagnet 6 from rotating in the cavity that valve gap 1 and valve body 2 form effectively, thereby has avoided electromagnet 6 its insulated paint in rotation process to wear and tear, and has improved working life; Meanwhile, this means of fixation installation of electromagnet 6 of being more convenient for;
The interior one-time positioning processing of valve body 2 circular hole, and process circular hole without additionally locating at the interior secondary of valve gap 1, thus simplify the processing technology of valve gap 1 and valve body 2, reduce cost;
Realized the automatic control of this solenoid valve by pressure transducer 12, temperature transducer 13 and the displacement transducer 14 adding on valve body 2;
The left adjustment block 16 adding and the thickness of right adjustment block 17 can be according to left inside spool 4 and the actual required movement travel designs of right inside spool 5;
The pole number of electromagnet 6 is 6 o'clock electromagnet magnetic circuit reluctance minimums, Number of ampere turns maximum, electromagnetic force maximum; The coil turn of electromagnet 6 is 20 o'clock, and electromagnetic attraction is tending towards saturated (maximum); When the thickness of armature 7 is 2.5～3.0mm, armature 7 and electromagnet 6 are operated near maximum permeability point, magnetic circuit reluctance minimum, electromagnetic force maximum.
In sum, the present invention has simple in structure, and control accuracy is high, and flow is large, fast response time, long service life, when use pipeline connect simple, the feature such as the simple and cost of processing is low.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
