Specific embodiment

Below in conjunction with the accompanying drawings this utility model is further described.

The high energy-saving electromagnetic valve of a kind of self-sustaining as shown in Figures 1 to 7, the valve being equipped with valve body 1 including valve body 1 Core assembly, valve body 1 is respectively equipped with air inlet 11 and gas outlet 12, is provided with valve port 13 in valve body 1, gas outlet 12 pass through valve port 13 with Air inlet 11 connects.

Core assembly includes plunger tube 2, and plunger tube 2 is fixedly connected with valve body 1 by pressing plate 3 it is preferable that pressing plate 3 and valve Body 1 is threaded.The outside of plunger tube 2 is arranged with coil block 21, and inside plunger tube 2, from top to bottom string is provided with dynamic iron core successively 4th, static iron core 5 and ratchet assembly.In order to improve electromagnetic induction value of the present utility model, to reduce startup power, static iron core 5 is close The end of dynamic iron core 4 is provided with tapered protrusion portion 51, and the corresponding end-faces of dynamic iron core 4 are provided with the taper matching with tapered protrusion portion 51 Groove portion 41.Ratchet assembly includes ratchet parent 6, presses wheel 7, runner 8 and back-moving spring 9, and ratchet parent 6 is fixed on plunger tube 2 Inside, in order to easy for installation, the bottom peripheral edge of ratchet parent 6 is extended with bulge loop 61, and bulge loop 61 is pressed located at plunger tube 2 and valve body 1 Between, press wheel 7 and runner 8 is axially moveable is installed in ratchet parent 6, and press wheel 7 and engage with runner 8.

Dynamic iron core 4 passes through ejector pin 10 and presses wheel 7 and offset cooperation, and the bottom of runner 8 is provided with and valve port 13 sealing coordinates Chock plug 14, supports between runner 8 and chock plug 14 and is provided with chock plug spring 15, and back-moving spring 9 supports between valve body 1 and runner 8；Ratchet It is additionally provided with the muscle groove 62 for pressing wheel 7 and runner play about 8 in parent 6, there is in muscle groove 62 the locking in low level for runner 8 The second positions 622 in high-order locking for the wheel 7 are pressed in one position 621, confession.

This utility model dynamic iron core 4 with the linkage principle of ratchet assembly is: during coil block 21 energising, dynamic iron core 4 meeting exists Pass through ejector pin 10 promotion under electromagnetic force and press wheel 7, promote runners 8 along the downward play of muscle groove 62 by pressing wheel 7, press wheel 7 outer walls and set The wheel convex tendon 71 of pressing put makes to press wheel and 7 will not rotate with respect to ratchet parent, when runner 8 moves to adjacent to primary importance 621, Runner 8 will make the runner convex tendon 81 of runner 8 outer wall and muscle groove 62 misplace, runner 8 because rotating with pressing the engagement taking turns 7 Turn an angle, if now coil block 21 power-off, due to the effect of back-moving spring 9, runner 8 is just snapped into primary importance 621, so that runner 8 position is locked；When dynamic iron core 4 pushes against again and presses wheel 7, runner 8 can be female with respect to ratchet again Body 6 rotates so that the runner convex tendon 81 of runner 8 outer wall is alignd with muscle groove 62 relevant position, if now coil block 21 power-off, multiple Position spring 9 will promote runner 8 and press wheel 7 and be synchronized with the movement to, making to press wheel 7 in situ and be locked in the second position 622.

This utility model, when using, is controlled the working condition of dynamic iron core 4 by coil block 21, and in back-moving spring 9 Under mating reaction, when dynamic iron core 4 is passed through ejector pin 10 and promote to press wheel 7, and when making primary importance 621 that runner 8 is located at muscle groove 62, plug 14 are in close contact with valve port 13, and this utility model is closed, and now makes coil block 21 power-off, this utility model is just It is in normally off；When dynamic iron core 4 is passed through ejector pin 10 and promote to press wheel 7, and when making to press the second position 622 that wheel 7 is located at muscle groove 62, Chock plug 14 is separated with valve port 13, and air inlet 11, valve port 13 and gas outlet 12 sequentially turn on, and this utility model is in opening, Now make coil block 21 power-off, this utility model is just in normally open.

In sum, this utility model need not make coil block 21 be energized for a long time, just can maintain a normally open (or normally closed) Working condition, service life is longer, effects of energy conservation and environmental protection preferably, and compared with prior art self-holding electromagnetic valve, this reality With new due to only needing to arrange a core assembly, and ratchet assembly is arranged on the inside of plunger tube 2, is not only simple in structure conjunction Reason, compact, manufacturing cost is relatively low, but also advantageously reduces the design difficulty of control circuit.

The outside of core assembly is covered with magnetic conduction sheath 16, and the top of magnetic conduction sheath 16 is provided with end cap 161, magnetic conduction sheath Threadeded with pressing plate 3 in 16 bottom, magnetic conduction sheath 16 is effectively protected to coil block 21, extends this utility model Service life.

In order that coil block 21 is easy to assembly, position degree is higher, it is provided between coil block 21 and end cap 161 and leads Magnetic sheet 171, supports successively between coil block 21 and pressing plate 3 and is provided with lower magnetic conductive board 172 and pushing top spring 173, by using elasticity Assembling mode, not only effectively reduce rigging error so that assembly precision is higher, certainty be installed more preferably so that Coil block 21 is in constant tightening state all the time, makes coil be difficult to generate heat, the life-span is higher.

Support between the top of dynamic iron core 4 and plunger tube 2 and be provided with power assistant spring 18, power assistant spring 18 is used for making dynamic iron core 4 have There is the movement tendency towards static iron core 5 direction.By power assistant spring 18 is set so that dynamic iron core 4 ejector pin 10 is had certain just Beginning active force, such that it is able to reduce coil turn, reduces manufacturing cost.

Ejector pin 10 passes axially through static iron core 5, and is formed with fit-up gap 19 between ejector pin 10 and static iron core 5.Work as line Coil assembly 21 is energized, and makes dynamic iron core 4 towards when moving in static iron core 5 direction, the air between dynamic iron core 4 and static iron core 5 is through assembly building Gap 19 slowly flows out, with this to 4 certain cushioning effects of dynamic iron core, it is to avoid presses and makes because of quick washing between wheel 7 and runner 8 Become to damage, extend service life.

The outer wall of ratchet parent 6 is provided with raised line 63, by arranging raised line 63, effectively increases ratchet parent 6 and every magnetic Tautness between pipe 2.

Valve body 1 is provided with two gas outlets 12, and by arranging two gas outlets 12, user is permissible according to actually used demand Selectivity uses, thus improving easy-to-use degree of the present utility model further.

The flow regulator 20 of the output flow for adjusting gas outlet 12 is provided with valve body 1, is adjusted by arranging flow Section device 20, user can adjust output flow as needed manually, easy to use, vdiverse in function.

The above is only better embodiment of the present utility model, therefore described in all patent claims according to this utility model Construction, the equivalence changes done of feature and principle or modification, be all included in this utility model patent claim.
