Embodiment
In conjunction with Fig. 1-4, example structure schematic diagram for a kind of guide electromagnetic valve of the utility model, comprise and be provided with the primary seal spool 3 being arranged in main valve body 16, described primary seal spool 3 is connected with acting chamber 19 by piston and connecting rod 8, the both sides of acting chamber 19 are provided with reservoir pressure solenoid valve 25 and pressure release electromagnetic valve 26, reservoir pressure solenoid valve 25 is connected with main valve body 16 by guide valve blocks 11, and communicate with main valve body 16 by guide's medium holes 23, in main valve body 16, be provided with the high pressure valve pocket 20 corresponding with the chamber 19 of doing work, described primary seal spool 3 is located in high pressure valve pocket 20, high pressure valve pocket 20 communicates with medium inlet 17, on described primary seal spool 3, cover has main guide springs 2, main guide springs is supported in fixed base 1, in described reservoir pressure electromagnetic valve body 25, be provided with pilot chamber 21, this pilot chamber 21 communicates with guide's medium holes 23, in pilot chamber 21, be provided with the forward sealed valve core 13 of slip, forward sealed valve core 13 is provided with guide springs 12, guide springs 12 is bearing in iron core sleeve 7, after forward sealed valve core 13, be provided with fixing iron core 15, forward sealed valve core 13 and iron core 15 are outer by being provided with iron core sleeve 7, and iron core sleeve 7 outsides are provided with electromagnetic coil 14, in described pressure release electromagnetic valve 26, be provided with acting ancillary chamber 2,2, this acting ancillary chamber 22 communicates with atmosphere, the reverse sealed valve core 6 that is provided with slip in acting ancillary chamber 22, oppositely sealed valve core 6 is provided with guide springs 12, and guide springs 12 is bearing in iron core sleeve 7, oppositely after sealed valve core 6, be provided with iron core 5 with holes, the end in iron core with holes 5 holes is pressure relief opening 24, reverse sealed valve core 6 and the outer cored cover 7 of iron core with holes 5, iron core sleeve 7 peripheral hardware electromagnetic coils 14, described acting chamber 19 is provided with valve gap 9, and valve gap 9 is fixed on main valve body 16 by screw 10, described junction is provided with rubber pad and/or rubber washer.
Under normal circumstances, in the pilot chamber 21 that medium enters reservoir pressure electromagnetic valve body from entrance 17 and the high pressure valve pocket 20 of main valve body 16, forward sealed valve core 13 is pushed down, cut off medium towards the path of acting chamber 19, and reverse sealed valve core 6 in pressure release electromagnetic valve body is all the time in opening state, if there is medium to enter acting chamber 19, medium can discharge automatically by the relief hole 24 on iron core 5 with holes.After two electromagnetic coils 14 are switched on simultaneously, iron core 15 in reservoir pressure electromagnetic valve body produces magnetic force, pull forward sealed valve core 13, medium enters acting chamber 19, and the iron core with holes 5 in pressure release electromagnetic valve body also produces magnetic force simultaneously, pull reverse sealed valve core 6, oppositely sealed valve core 6 seals the iron core hole 24 of iron core 5 with holes, and the pressure of acting chamber 19 increases, and promotes piston and connecting rod 8 motions, connecting rod backs down primary seal spool 3, and the at this moment entrance 17 of main valve body 16 and outlet 18 directly communicates.After removing the power supply of two electromagnetic coils 14, iron core 15 magnetic forces in reservoir pressure electromagnetic valve body disappear, forward sealed valve core 13 playbacks under guide springs 12 and high-pressure medium effect, medium no longer enters acting chamber 19, iron core with holes 5 magnetic forces in pressure release electromagnetic valve body also disappear simultaneously, oppositely sealed valve core 6 playback under guide springs 12 effects, the iron core hole 24 of iron core 5 with holes is open, discharge the pressure of acting chamber 19, the pressure of chamber 19 of now doing work reduces, primary seal spool 3 playbacks under main guide springs 2 and high-pressure medium effect, piston and connecting rod 8 is pushed back simultaneously, at this moment the entrance 17 of main valve body 16 and outlet 18 no longer communicates.
Electromagnetic coil of the present utility model only plays forward sealed valve core and the oppositely sealed valve core effect controlled, directly do not control the movement of primary seal spool, therefore can control the medium fluid of cross section super large, pressure superelevation, have advantages of that power consumption is low, volume is little, it is good to open and close flexibility, this guide electromagnetic valve is not only applicable to the control of pressurized container, also be applicable to the control of pressure piping, and can automatically reset as required after valve opening.
Those ordinary skill in the art's simple change and replacement are all within protection domain of the present utility model.
