It is dynamic to complete overbottom pressure protection.
In order to solve the above technical problems, the technical solution of the utility model is：Design and a kind of maintain function with overbottom pressure
Magnetic valve, including shell, it is characterised in that：Skeleton is installed in shell, cavity is offered in skeleton, is opened up on the roof of skeleton
Have the first passage, the second passage offered in side wall, the first passage and the second passage connect cavity, in cavity from
Bottom to top is sequentially installed with fixed core, dynamic iron core and piston, and the periphery of fixed core is wound with magnet coil, fixed core and dynamic iron core
Between be provided with the first elastomer, be provided with the second elastomer between dynamic iron core and piston, the top external diameter of piston is more than the first ventilation
The internal diameter in hole.
Preferably, the top of the piston is provided with sealing gasket.
Preferably, the roof of the skeleton is tapered in what is sunk, and the first passage is located at cone tip part.
Preferably, the top of the dynamic iron core offers the first guide groove, and piston can be inserted into the first guide groove.
Preferably, the bottom of the dynamic iron core offers the second guide groove, and the first elastomer is in the second guide groove with moving
Iron core is connected.
Preferably, first elastomer and the second elastomer are spring.
Compared with prior art, the beneficial effects of the utility model are：
1st, due to the structure that the utility model is mutually equipped with using dynamic iron core with piston, when needing discharge gas, electromagnetic wire
Enclose electric, fixed core produces suction, forces dynamic iron core to overcome the elastic force of the first elastomer to move down, dynamic iron core and piston space
Distance increase, the elastic force of the second elastomer reduces, and in the presence of piston self gravitation and compressed gas, piston is to bottom side
To movement, depart from the closure to the first passage, now path is formed on the top of the first passage, the second passage and inner chamber,
Gas is discharged by the path, during gas discharges, the active force of piston is gradually reduced, waits to be not enough to overcome first
During the elastic force of elastomer, the first elastomer will promote piston to be moved to top, block on the first passage so that residual gas
It is not then exhausted from, completes overbottom pressure protection.
2nd, because the top of piston is provided with sealing gasket, the sealing property of top land is added, can fully cut off gas circuit.
3rd, because the roof of skeleton is tapered in what is sunk, the first passage is located at cone tip part so that the first passage is located at
Protuberance, it is easy to block.
4th, because the top of dynamic iron core offers the first guide groove, piston can be inserted into the first guide groove, the work of constraint
The moving direction of plug, it is ensured that the top of piston is controlled the accurate break-make of the first passage.
5th, because the bottom of dynamic iron core offers the second guide groove, the first elastomer in the second guide groove with dynamic iron core phase
Connection, the moving direction of dynamic iron core can be preferably constrained, so as to be that the moving direction for ensuring piston lays the foundation.
6th, the utility model is simple in construction, can realize overbottom pressure during gas discharge by the cooperation of piston and dynamic iron core
Control, is easy to popularization and application in industry.

Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
The utility model is in shown in Fig. 4 during state, is bottom close to following one end, correspondingly close to above one
End is defined as top.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the utility model is provided with skeleton 2 in shell 1, is opened up in skeleton 2 free
Chamber 10, the roof of skeleton 2 is tapered in what is sunk, and cone tip part offers the first passage 4, and second is offered in the side wall of skeleton 2
Passage 3, the first passage 4 connect cavity 10 with the second passage 3.In cavity 10 fixed core is sequentially installed with from bottom to top
5th, dynamic iron core 7 and piston 8, the periphery of fixed core 5 are wound with magnet coil 6, and the top of dynamic iron core 7 offers the first guide groove
13, piston 8 can be inserted into the first guide groove 13, be connected with second spring 12 between dynamic iron core 7 and piston 8, under dynamic iron core 7
Portion offers the second guide groove 14, and the first spring 11 is connected with fixed core 5, and the other end of the first spring 11 is oriented to positioned at second
In groove 14, and it is connected with dynamic iron core 7, the top of piston 8 is provided with sealing gasket 9, and the external diameter of sealing gasket 9 is more than the first passage
4 internal diameter.
In use, the top of skeleton 2 is arranged in air spring, the second passage 3 is located at outside air spring.Positive reason
Under condition, magnet coil 6 is in off-position, and dynamic iron core 7 is pushed to the direction of piston 8 under the effect of the first spring 11, drives second
Spring 12 and piston 8 move to the top orientation of skeleton 2, and simultaneously in the presence of second spring 12, the closure of its top exists piston 8
On first blow vent, because the active force of the first spring 11 and second spring 12 is sufficiently large, cause the compression in air spring empty
Gas pushes away not open piston 8, realizes the sealing to air spring, maintains the rigid demand of air spring.
When needing to increase the flexibility of air spring, the power supply of magnet coil 6 is connected, under electromagnetic action, fixed core 5 produces
Raw suction so that dynamic iron core 7 overcomes the elastic force of the first spring 11 to be moved to the side of fixed core 5, and now, the elastic force of the first spring 11 increases
Greatly, and because the distance between dynamic iron core 7 and piston 8 increases, the elastic force of second spring 12 then reduces, in the self gravitation of piston 8 and
In the presence of compressed gas, piston 8 moves to bottom direction, departs from the closure to the first passage 4 so that the first passage 4,
Path is formed on the top of the second passage 3 and inner chamber, and gas is discharged by the path, during gas discharges, to piston 8
Active force be gradually reduced, when being not enough to overcome the elastic force of the first spring 11, the first spring 11 will promote piston 8 to be moved to top
It is dynamic, block on the first passage 4 so that residual gas is not then exhausted from, and completes overbottom pressure protection.
It is described above, only it is preferred embodiment of the present utility model, is not that other forms are made to the utility model
Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of change.But it is every without departing from the content of the technical scheme of the utility model, it is real according to technology of the present utility model
Any simple modification, equivalent variations and the remodeling that confrontation above example is made, still fall within the guarantor of technical solutions of the utility model
Protect scope.
