Description
Technical field
The present invention relates to Solenoid Valve Technology field, specifically a kind of miniature reed-type solenoid valve.
Background technique
~ gap is O.06mm required O.05 between the tradition mangetic core assembly of miniature electromagnetic valve and coil block, smooth and easy mainly in order to ensure valve core movement, but the size in this gap has a certain impact for the valve seal performance of repeatedly repetitive operation, gap is larger, impression dislocation is more obvious, and its sealing repeatability is also poorer.
It can thus be appreciated that the impression that traditional miniature electromagnetic valve exists does not overlap, seal poor stability, problem that the life-span is low.
Summary of the invention
For defect of the prior art, the object 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 arranged in the chamber of coil block from left to right successively, and described valve seat and inlet union are fixed in the two ends, left and right of coil block respectively;
Described mangetic core assembly comprises block, sealing block, the first armature, reed and the second armature that left-to-right sets gradually, wherein, described first armature, to be welded and fixed respectively by being press-fitted between reed and the second armature, described block is fixedly connected with the first armature, and described sealing block is arranged between block and the first armature.
Preferably, described valve seat and between inlet union and coil block by being welded and fixed.
Preferably, described reed point is welded on the second armature, and described block and the 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 adds reed structure on mangetic core assembly, in valve working process, utilizes reed to carry out centering location to spool, solves the problem of impression dislocation, utilizes spring to provide seal pressure simultaneously, improve sealing stability and the operating life of valve;
2 while adding reed, retain original spring structure, in off position, provided the sealing force of valve by spring, and traditional reed valve is the sealing force being provided valve by reed, owing to remaining spring structure, reed only plays locating function, utilizes spring to apply sealing force, reed load is little, suffered by reed, stress reduces greatly, reed Miniaturizable, and valve can lighting.
In sum, miniature reed-type solenoid valve provided by the invention, has sealing good stability, long service life, lightweight beneficial effect.

By reading the detailed description done non-limiting example with reference to the following drawings, other features, objects and advantages of the present invention will become more obvious:
Fig. 1 is the sectional view of the miniature reed solenoid valve of the present invention;
Fig. 2 is the sectional view of mangetic core assembly of the present invention;
Fig. 3 is reed structure figure of the present invention;
In figure: l is valve seat, 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 the first armature, and 10 is reed, and 11 is the second armature.
Embodiment
Below embodiments of the invention are elaborated: the present embodiment is implemented under premised on technical solution of the present invention, give detailed mode of execution and concrete operating process.It 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 refer to figure l to Fig. 3, present embodiments provide 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 arranged 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, left and right of coil block 5 respectively; During assembling, first by mangetic core assembly 2, the chamber of coil block 5 put into successively by residual shim 3, spring 4, then loads valve seat l and is fixed, finally valve seat l and inlet union 6 are welded with coil block 5.
Described mangetic core assembly comprises the block 7, sealing block 8, first armature 9, reed 10 and the second armature 11 that set gradually from left to right, wherein, described first armature 9, to be welded and fixed respectively by being press-fitted between reed 10 and the second armature ll, described block 7 is fixedly connected with the first armature 9, and described sealing block 8 is arranged between block 7 and the first armature 9.During assembling, first reed 10 is welded on the second armature 11, then by being press-fitted welding, the first armature 9, reed 10 and the second armature ll is fixed, putting into sealing block 8 and block 7, finally by spot welding, block 7 and armature 19 being fixed.
The miniature reed-type solenoid valve that the present embodiment provides, its working procedure is:
When solenoid valve is not energized, reed keeps free state, provides sealing force by spring; When after solenoid valves, mangetic core assembly is setting in motion under the effect of electromagnetic attraction, valve opening, and now the amount of deformation of reed is the aperture of valve; After solenoid valve power-off, mangetic core assembly resets under the acting in conjunction of spring force and spring force, valve closing.In the process of repeatedly moving, owing to there being reed to exist, mangetic core assembly can not rotate and offset, impression high conformity, and valve seal is stablized, the life-span is high.
Above specific embodiments of the invention are described.It is to be appreciated that the present invention is not limited to above-mentioned particular implementation, those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present invention.
