Description
Technical field
The utility model relates to solenoid valve field, relates in particular to a kind of mangetic core assembly and uses the solenoid valve of this mangetic core assembly.
Background technique
Sliding valve style solenoid valve is used by people widely because manipulating conveniently, existing sliding valve style solenoid valve comprises electromagnet and mangetic core assembly, mangetic core assembly comprises valve seat, valve seat has the valve pocket that guide direction is extended along fore-and-aft direction, in valve pocket, guiding movement is equipped with spool, on the action output terminal of electromagnet, be connected with the push rod being in transmission connection with described spool rear end, on valve seat, be sequentially set with first and cross gas passage, second crosses gas passage and the 3rd crosses gas passage, the first bearing of trend of crossing gas passage and valve pocket to extend axially direction identical, first crosses gas passage is communicated with the space of spool rear side, spool has in reciprocating process to move backwards with shutoff the 3rd in valve pocket crosses gas passage, be communicated with first, second crosses the first working position of gas passage, spool also has to move forward with shutoff first crosses gas passage, be communicated with second, the 3rd crosses the second working position of gas passage.Between spool and valve seat, be provided with and force the spring of spool towards the first working position direction motion.When use, pressurized gas are entered in solenoid valve by the 3rd mistake gas passage, by the 3rd gas that gas passage enters excessively, spool is applied to one and force the atmospheric pressure of spool towards the first working position direction motion, when no electric circuit, spool be subject to spring and atmospheric pressure acting in conjunction and in the first working position, second crosses gas passage and the 3rd crosses gas channel connection, first crosses gas passage by spool shutoff, by the 3rd cross gas passage to second cross in the container of gas channel connection and inflate; When energising, electromagnet applies the active force of direction forward to push rod, push rod promotes spool and overcomes acting force of the spring and atmospheric pressure and make spool move forward to the second working position, the 3rd crosses gas passage by spool shutoff, first, second crosses gas channel connection, makes thereby reach the object of crossing the container decompression of gas channel connection with second.The problem that existing this solenoid valve exists is: be first at needs spool in the second working position, when the second mistake gas channel connection, electromagnet must apply the active force that can overcome acting force of the spring and atmospheric pressure to push rod, just can make spool move forward, and often because atmospheric pressure is larger, this just needs electromagnet to provide larger active force to push rod, to having relatively high expectations of electromagnet, this just must realize by the weight and volume that increases electromagnet, the increase of electromagnet weight and volume has not only increased the fabricating cost of whole solenoid valve, the power consumption that has increased solenoid valve is user cost, also can increase the physical dimension of whole solenoid valve simultaneously, the miniaturization that is unfavorable for solenoid valve is made.

Solenoid valve of the present utility model can be realized multiple-working mode: 1, commutation work pattern, gas is crossed gas passage access solenoid valve by second, under powering-off state, spool is in the second working position (shown position), first crosses gas passage by shutoff, second, third crosses gas channel connection, and gas is crossed gas passage from the 3rd and blown out; In the time that solenoid valve is switched on, push rod promotion spool overcomes acting force of the spring and moves forward, and spool is in the first working position, the 3rd crosses gas passage by shutoff, and first, second crosses gas channel connection, and gas is crossed gas passage through first and blown out, in whole process, solenoid valve uses as two-bit triplet selector valve.2, normally closed pressure release: gas is crossed gas passage from first and accessed solenoid valve, under powering-off state, spool is in the second working position (shown position), and first crosses gas channel enclosed, and valve is in normally off; In the time that solenoid valve is switched on, push rod promotion spool overcomes spring force and moves forward, spool is in the first working position, and first, second crosses gas channel connection, and gas is crossed gas passage from second and blown out, after power-off, spool is got back to the first working position, and now second, third crosses gas channel connection, and the second air pressure of crossing in gas passage is crossed the release of gas passage by the 3rd, in whole course of action, solenoid valve uses as normally closed Decompression valves.3, often open pressure release: gas is crossed gas passage from the 3rd and accessed solenoid valve, under powering-off state, spool is in the second working position (shown position), and first crosses gas channel enclosed, and gas is crossed gas passage from second and blown out; In the time that solenoid valve is switched on, push rod promotion spool overcomes spring force and moves forward, and spool is in the first working position, first, second crosses gas channel connection, gas in the second mistake gas passage is crossed gas passage from first and is blown out release, and in whole course of action, solenoid valve plays the effect of switch and pressure release.The first annular groove front side pressure-bearing cell wall, the axial bearing area of the first annular groove rear side pressure-bearing cell wall is identical, this makes in the time that the 3rd crosses gas passage access gas, gas is to the first annular groove front side pressure-bearing cell wall, rear side pressure-bearing cell wall produces the active force of opposite sign but equal magnitude, this cancels each other to active force, same reason is crossed gas passage second, when the first mistake gas passage connects gas, gas is 0 to the active force of spool, in above-mentioned so each mode of operation, spool is in the time being moved to the first working position by the second working position, electromagnet only needs to overcome the active force of spring, when valve core movement, only use the thrust of considering spring force and push rod, ensure the reliability of electromagnetic valve work.According to the working principle of coil, such equilibrium structure can significantly be saved the electric energy of the loss of solenoid valve own in addition, reduces power consumption.
In other embodiment of this solenoid valve: the first annular groove front side pressure-bearing cell wall can be not identical with the axial bearing area of the first annular groove rear side pressure-bearing cell wall, now gas can not be offset completely to the active force of spool, but also can partial offset, can reach equally the object that reduces electromagnet power demand, the second annular groove front side pressure-bearing cell wall can be different from the axial bearing area of the second annular groove rear side pressure-bearing cell wall as a same reason, and the footpath, chamber of the first valve pocket section, the second valve pocket section also can be different; Each pressure-bearing cell wall of the first annular groove, the second annular groove can also be straight wall construction, now can realize and the sealing of the corresponding notch of the 3rd annular groove by seal lip is set on the first annular groove rear side pressure-bearing cell wall, the second annular groove front side pressure-bearing cell wall; In the time not needing solenoid valve to have normally closed pressure release mode of operation, the second annular groove also can not established, and now can on spool, be provided for being communicated with first, second at spool during in the first working position and cross the gas channel of gas passage; The 3rd annular groove also can not established, and now can utilize the seal ring sealing second arranging on the outer circumferential face of annular protrusion or outer circumferential face to cross gas passage, and now valve pocket can not established, and valve pocket is arranged on valve body completely.
The embodiment of mangetic core assembly is as shown in Figure 2: the concrete structure of mangetic core assembly is identical with the mangetic core assembly described in above-mentioned each solenoid valve embodiment, is not described in detail in this.
