Embodiment
As shown in Figure 1, a kind of direct-acting electromagnetic valve, including coil case 1, coil block 2, valve body 3, dynamic iron core 4, quiet iron
Core 5, reset spring 6 and sealing element 7, the coil block 2 is set in coil case 1 to be connected with external power supply, and when energization drives
Dynamic iron core 4 is slided, and the valve body 3 is equipped with a valve chamber, has medium flow channel, medium flow pass and company in the valve chamber
The valve port of logical medium flow channel and medium flow pass, the 4 activity cooperation of dynamic iron core are described in the centre of coil block 2
The lower end of dynamic iron core 4 is equipped with sealing element 7, and sealing element 7 is with the mobile opening of dynamic iron core 4 or closes valve port, outside 4 lower end of dynamic iron core
Side is arranged with reset spring 6, and the upper and lower side of the reset spring 6 abuts coil case 1 and sealing element 7, the dynamic iron core 4 respectively
For hollow tubular structure, it is fixedly provided with Buffer Unit 8, for buffering effect of the dynamic iron core 4 to 5 direction of static iron core
Power.Under original state, coil block 2, which is not powered, does not generate magnetic force, under the action of reset spring 6,7 plugging valve of sealing element
Mouthful, preferred reset spring 6 is taper spring；When the coil is energized, solenoid valve starts, magnetic attraction of the dynamic iron core 4 in static iron core 5
Under move up, sealing element 7 moves up opening valve port, and medium (such as gas) can enter medium outflow from medium flow channel
Channel, because dynamic iron core 4 and static iron core 5 are all stainless steel material, dynamics is larger when mutually collision is attracted, 4 He of easy damaged dynamic iron core
Static iron core 5, the utility model set Buffer Unit 8 inside dynamic iron core 4, can be when dynamic iron core 4 hits static iron core 5, and buffering is dynamic
Colliding forces of the iron core 4 to static iron core 5.
In the present embodiment, the Buffer Unit 8 is buffer spring 81.It is absorbed by buffer spring 81 and reduces dynamic iron core 4
Vibration and impact to static iron core 5 increase stability when solenoid valve is opened, and greatly reduce when reset spring 6 rebounds suddenly
Rebound displacement avoids solenoid valve from opening ineffective.Preferably, buffer spring 81 is made of 2Cr18Ni9 stainless steel, 2Cr18Ni9
Stainless steel have high corrosion resistance, have higher plasticity and toughness under low temperature, room temperature and high temperature, have both hardness with it is tough
Property, it can preferably play the role of buffering.
In the present embodiment, the Buffer Unit 8 further includes upper rubber pad 82 and lower rubber pad 83, the buffer spring 81
Between upper and lower rubber pad.When rubber pad bears pressure or hits, since hysteresis deformation has excellent absorption impact and hits
The characteristic hit can slow down the release of active force；Although vibration and impact can be absorbed in buffer spring 81, buffer spring 81 is certainly
Body also has reciprocating motion, and the movement of buffer spring 81 is transmitted to rubber spacer, is consumed by the hysteresis deformation of rubber spacer,
Meanwhile the displacement transfer of rubber spacer can also be consumed to buffer spring 81 by the deformation of buffer spring 81；Therefore, pass through
The synergistic effect of buffer spring 81 and rubber spacer, can cancel out each other mutual deformation impact, so that dynamic iron core 4 is to static iron core
5 shock dynamics is impaired to minimum, and electromagnetic valve work is reliable and stable.

Shell 1 is fixedly connected.The upper and lower side of the reset spring 6 abuts support plate 9 and sealing element 7 respectively, and spring is connected to support
On plate 9, influence of the elastic force of the generation of the deformation process of spring to coil block 2 is effectively reduced, guarantees that supply current is steady.
In the present embodiment, 9 end face of support plate and 4 clearance fit of dynamic iron core.Support plate 9 is oppositely arranged, and forms clamping
The state of dynamic iron core 4, can limit the radial displacement of dynamic iron core 4, guarantee dynamic iron core 4 in moving process it is steady always it is vertical on
It moves, kinetic stability further increases, and the vibration frequency of dynamic iron core 4 is effectively reduced, solenoid valve motion stability is reliable.
In the present embodiment, the static iron core 5 is hollow tubular structure, forms gas vent 51,51 communicating valve of gas vent
Chamber and the external world.The gas vent 51 communicated with valve chamber is set on the utility model static iron core 5, during dynamic iron core 4 moves up, medium into
Behind the gap for entering valve chamber, dynamic iron core 4 and coil block 2, into gas vent 51, i.e., medium is for dynamic iron core 4, reset spring 6
The pressure sum of zero applied with sealing element 7, support plate 9 is not influenced the frictional resistance of dynamic iron core 4 by medium pressure, and is answered
Position spring 6 is not also influenced the elastic force of dynamic iron core 4 by the pressure of fluid, in this way moves not only sealing element 7 and dynamic iron core 4
After vapour lock greatly reduces, and keeps gas flowing smooth, and the dynamic iron core 4 that is attracted of the gas vent 51 on static iron core 5 is closed, move
4 lower part pressure of iron core increases, and forms the power of support dynamic iron core 4, can drop low standby current, and then reduce energy consumption；Under dynamic iron core 4
During shifting, the gas vent 51 on static iron core 5 is opened, and the medium in valve chamber flows up, and is discharged from there, transports dynamic iron core 4
The suspension effect of air supporting is formed during dynamic, motion process is more steady, also, will not generate that side gas is more, side
The few deviation phenomenon of gas.
In the present embodiment, support plate 9 and pedestal and 1 junction of coil case are equipped with gasket seal 10, guarantee the tight of connection
Solidity.
In the present embodiment, support plate 9 and pedestal and 1 junction of coil case are additionally provided with O-ring seals 11, improve sealing effect
Fruit.
