The valve spool assembly, the non-magnetic gasket and the spring are sequentially mounted in a cavity of the coil assembly from left to right, and the valve seat and the inlet connector are respectively fixedly connected to the left end and the right end of the coil assembly; and the valve spool assembly comprises a check block, a sealing block, a first armature, a reed and a second armature which are sequentially arranged from left to right, the first armature, the reed and the second armature are respectively fixedly welded with one another in a press-fit manner, the check block is fixedly connected with the first armature, and the sealing block is arranged between the check block and the first armature. The problem of pressing mark dislocation is solved, shortcomings of poor sealing stability and short service life are overcome, and the miniature reed electromagnetic valve has the advantages of good sealing stability, long service life and light weight.
Description
Technical field
The present invention relates to the solenoid valve technical field, specifically is a kind of miniature reed-type solenoid valve.
Background technique
O.05 require between the tradition mangetic core assembly of miniature electromagnetic valve and the coil block has～O.06mm gap, mainly be smooth and easy in order to ensure valve core movement, but the size in this gap has certain influence for the valve seal performance of repeatedly repetitive operation, the gap is more big, the impression dislocation is more obvious, and its sealing repeatability is also more poor.
Hence one can see that, and the impression that traditional miniature electromagnetic valve exists does not overlap, seals poor stability, low problem of life-span.
Summary of the invention
At defective of the prior art, the purpose of this invention is to provide a kind of miniature reed-type solenoid valve.
The present invention is achieved by the following technical solutions.
A kind of miniature reed-type solenoid valve, comprise valve seat, mangetic core assembly, residual shim, spring, coil block and inlet union, described mangetic core assembly, residual shim and spring are installed in the chamber of coil block from left to right successively, and described valve seat and inlet union are fixed in the two ends, the left and right sides of coil block respectively;
Described mangetic core assembly comprises block, sealing block, first armature, reed and second armature that left-to-right sets gradually, wherein, fixing by being press-fitted welding respectively between described first armature, reed and second armature, described block is fixedlyed connected with first armature, and described sealing block is arranged between block and first armature.
Preferably, fixing by welding between described valve seat and inlet union and the coil block.
Preferably, described reed point is welded on second armature, and described block and first armature are fixed by spot welding.
Preferably, described reed is single reed.
The present invention compared with prior art has following technical characterstic:
L has increased reed structure at mangetic core assembly, in the valve working process, utilizes reed that spool is carried out the centering location, has solved the problem of impression dislocation, utilizes spring that seal pressure is provided simultaneously, has improved sealing stability and the operating life of valve;
2 when adding reed, keep original spring structure, in off position, provided the sealing force of valve by spring, and traditional leaf valve is the sealing force that valve is provided by reed, owing to kept spring structure, reed only plays locating function, utilizes spring to apply sealing force, the reed load is little, the suffered stress of reed reduces greatly, reed Miniaturizable, but valve lighting.
In sum, miniature reed-type solenoid valve provided by the invention has sealing good stability, long service life, lightweight beneficial effect.
Description of drawings
By reading the detailed description of non-limiting example being done with reference to the following drawings, it is more obvious that other features, objects and advantages of the present invention will become:
Figure l is the sectional view of the miniature reed solenoid valve of the present invention;

Among the figure: l is valve seat, and 2 is mangetic core assembly, and 3 is residual shim, and 4 is spring, and 5 is coil block, and 6 is inlet union, and 7 is block, and 8 is sealing block, and 9 is first armature, and 10 is reed, and 11 is second armature.
Embodiment
Below embodiments of the invention are elaborated: present embodiment is being to implement under the prerequisite with the technical solution of the present invention, has provided detailed mode of execution and concrete operating process.Should be pointed out that to those skilled in the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.
Please consult figure l to Fig. 3 simultaneously, present embodiment provides a kind of miniature reed-type solenoid valve, whole miniature reed-type solenoid valve comprises: valve seat l, mangetic core assembly 2, residual shim 3, spring 4, coil block 5 and inlet union 6, described mangetic core assembly 2, residual shim 3 and spring 4 are installed in the chamber of coil block 5 from left to right successively, and described valve seat l and inlet union 6 are fixed in the two ends, the left and right sides of coil block 5 respectively; During assembling, earlier with mangetic core assembly 2, residual shim 3, spring 4 are put into the chamber of coil block 5 successively, and the valve seat l that packs into then is fixed, and at last valve seat l and inlet union 6 are welded with coil block 5.
Described mangetic core assembly comprises block 7, sealing block 8, first armature 9, reed 10 and second armature 11 that sets gradually from left to right, wherein, fixing by being press-fitted welding respectively between described first armature 9, reed 10 and the second armature ll, described block 7 is fixedlyed connected with first armature 9, and described sealing block 8 is arranged between block 7 and first armature 9.During assembling, earlier 10 of reeds are welded on second armature 11, then by being press-fitted welding first armature 9, reed 10 and the second armature ll are fixed, put into sealing block 8 and block 7, by spot welding block 7 and armature 19 are fixed at last.
The miniature reed-type solenoid valve that present embodiment provides, its working procedure is:
When solenoid valve was not switched on, reed kept free state, provides sealing force by spring; After the solenoid valve energising, mangetic core assembly is setting in motion under the effect of electromagnetic attraction, valve opening, and this moment, the amount of deformation of reed was the aperture of valve; After the solenoid valve outage, mangetic core assembly resets valve closing under the acting in conjunction of spring force and reed power.In the process of repeatedly motion, owing to there is reed to exist, mangetic core assembly can not rotate and be offset, and impression high conformity, valve seal are stablized, the life-span height.
More than specific embodiments of the invention are described.It will be appreciated that the present invention is not limited to above-mentioned specific implementations, those skilled in the art can make various distortion or modification within the scope of the claims, and this does not influence flesh and blood of the present invention.
