The pressurising or release of chamber, and then opening or closing for diaphragm valve is controlled, it is wanted to meet oxygen concentrator confession/exhaust switching
It asks.
Preferably, the gasket in normally closed plug and normally opened plug is placed in respectively and on left cover and static iron core
Air inlet contacts and is formed certain decrement, forms end face seal.
The inside and outside round edge for being preferably located at valve mouth annular air scoop on left cover and static iron core carries out the processing of rounding angle.
Preferably, little spring is located between the normally closed plug and normally opened plug in armature, guarantees quiet under electromagnetic force
Iron core forms flexible compression amount with the gasket and valve mouth when the armature is engaged, being placed in normally opened plug.
Preferably, there is internal screw thread in valve casing opening side, cooperates with valve deck, and coil block is fixed on valve casing by static iron core
It is interior, it is completed rear rack-mount, bracket is fixed on valve body.
Preferably, valve body bottom surface is opened there are two air inlet, and side is provided with gas outlet.
Preferably, left cover and right cover intralamellar part are provided with gas circuit.
Compared with prior art, the present invention its remarkable advantage are as follows: (1) on static iron core valve mouth annular air scoop inside and outside circle
Side carries out the processing of rounding angle, has both reduced the contact area of valve mouth and gasket, improves sealing performance, and prevent valve mouth sharp edge
Cutting sealing pad damages, and improves service life and resistance to shock.(2) make normally opened plug become flexible by little spring to float
Component had not only guaranteed that static iron core was effectively attracted with armature under electromagnetic force, but also made gasket and or doorway formation decrement.
(3) left cover is connected to air inlet and air outlet with the gas circuit of right cover intralamellar part, reduces gas circulation length, increases flow.

Specific embodiment
The invention will be further described with reference to the accompanying drawings of the specification.
As shown in Figure 1 and Figure 2, the small-sized three-way magnetic valve of the big flow of quick response of the present invention, including right cover plate 1, valve casing
2, skeleton 3, coil 4, valve deck 5, bracket 6, valve body 7, left cover 8, gasket 9, normally closed plug 10, big spring 11, little spring 12,
Armature 13, normally opened plug 14, static iron core 15, wherein normally closed plug 10, normally opened plug 14, armature 13, little spring 12 and sealing
Pad 9 forms dynamic iron core 16, and gasket 9 is individually fixed in 14 groove of normally closed plug 10 and normally opened plug, and static iron core 15 passed through
Cooperation of being full of is fixed with valve casing 2, and skeleton 3 and coil 4 form coil block 17, and coil block 17 is fixed on valve casing by static iron core 15
In 2, there is internal screw thread in the opening of valve casing 2 side, and valve deck 5 is fixed by screw thread and valve casing 2, and bracket 6 is fixed on valve by screw
On body 7, the valve chest 2 that inside is fixed with static iron core 15 and coil block 17 is installed on bracket 6, dynamic iron core 16 is installed on branch
In 6 cylindrical cavity of frame, dynamic iron core 16 and static iron core 15 keep certain interval, right cover plate 1 and a left side under the effect of 11 elastic force of big spring
Cover board 8 is fixed by screw and valve body 7, and right cover plate 1 passes through the valve deck 5 that screw is fixed with valve casing 2 and will be threadedly coupled with valve casing 2
End face and 6 end face of bracket compress.As shown in figure 4, being provided with gas circuit on left cover 8 and right cover plate 1, space is saved, threeway is made
Electromagnetic valve structure is more compact.There is diversion trench in 13 side of armature and actuation face, and flow resistance when can effectively reduce gas flowing increases three
Three-way electromagnetic valve flow.
As shown in figure 3, a kind of three-way magnetic valve working principle that the big flow of quick response is small-sized is as follows: A mouthfuls are normally closed
Air inlet, B mouthfuls are normally opened air inlet, and side of valve body is provided with exhaust outlet.Three-way magnetic valve passes through the movement of dynamic iron core 16, realizes normal
It opens the switching of plug 14, normally closed plug 10 and valve mouth sealing relationship, and then realizes cutting for air inlet and exhaust outlet connected relation
It changes.Original state, big spring 11 are in compressive state, under initial tension of spring effect, the sealing that is placed in normally closed plug 10
