Description
Technical field
The utility model relates to Solenoid Valve Technology field, particularly relates to a kind of drive mechanism and swing link type diaphragm electromagnetic valve.
Background technique
Adopt the isolation solenoid valve of diaphragm type, be widely used in and all kinds ofly relate in the industry of the corrosive reagents such as liquid, be generally divided into direct-acting type and swing link type by motion mode.At present, swing link type threeway diaphragm electromagnetic valve, its typical structure as shown in Figure 1, mainly comprise rotating shaft 10, diaphragm 11, diaphragm skeleton 12, normally closed pressure head 13, lower spring 14, electromagnetic coil 15, buting iron 16, dynamic iron 17, slide block 18, upper spring 19, often open pressure head 20 and valve gap 21 etc., valve gap 21 is provided with public port 21a, normally closed port 21b and normal ported 21c.By the alternating action of electromagnetic force and upper and lower spring force, realize diaphragm 11 and rotate along rotating shaft 10, thus complete the switching of runner.
When electromagnetic coil 15 is energized, the adhesive of dynamic iron 17 is left behind and to be adjacent to buting iron 16 by electromagnetic force, lower spring 14 is compressed, therefore under the elastic force effect of upper spring 19, often open pressure head 20 promote diaphragm skeleton 12 drive diaphragm 11 around the shaft 10 rotate, slide block 18 and normally closed pressure head 13 are pushed open, now the normally closed port 21b of valve gap 21 opens with public port 21a and is communicated with.When electromagnetic coil 15 power-off, electromagnetic force disappears, dynamic iron 17, under the elastic force effect of lower spring 14, withstands slide block 18 and moves to valve gap 21 place, because lower spring 14 elastic force is much larger than upper spring 19, so, under lower spring 14 acts on, normally closed pressure head 13 promotes diaphragm skeleton 12 and drives diaphragm 11 10 to rotate around the shaft, and upper spring 19 is compressed, often open pressure head 21c to be open, now the normal ported 21c of valve gap 21 opens with public port 21a and is communicated with.
The major defect of prior art has:
1, under energising, power-off two states, the two ends of upper spring are spacing all not to be fixed, thus requires very harsh to the elastic force of upper and lower spring.
Suppose, diaphragm skeleton 12 keeps balance to be zero-bit (namely valve gap port 21a, 21b, 21c are all identical to diaphragm skeleton 12 perpendicular distance), and the decrement of upper spring 19 and lower spring 14 is respectively x
0, y
0, the valve gap 21 port sealing limit needs pressure f
0, when electromagnetic coil 15 is energized, slide block 18 does the straight line motion away from diaphragm skeleton 12, and amount of movement is set to l
1(relative zero-bit, lower with), meanwhile, upper spring 19 promotes the normal ported 21c that diaphragm skeleton 12 and diaphragm 11 prop up valve gap 21, and amount of movement is set to l
2(l
1>=l
2), then now, the decrement of upper spring 19 is: x
0-l
1-l
2, spring force should be at least f
0, the decrement of lower spring 14 is: y
0+ l
1, spring force is f
1.When electromagnetic coil 15 power-off, slide block 18 does straight line motion to barrier film skeleton 12 direction under the promotion of dynamic iron 17, thus makes barrier film skeleton 12 and diaphragm 11 prop up the normally closed port 21b of valve gap 21, and amount of movement is set to l
3(suppose both sides symmetry compression, l
3=l
1), then now, the decrement of upper spring 19 is: x
0+ 2l
3, spring force is f
2, the decrement of lower spring 14 is: Y
0-l
3, spring force is f
3.
Suppose, upper spring 19 rigidity is k
1, lower spring 15 rigidity is k
2, then upper spring 19 spring force that is energized is: f
0, spring to break power is: f
2=f
0+ k
1(l
1+ l
2+ 2l
3)>=f
0+ 4k
1l
2, lower spring 14 spring to break power is: f
3>=f
2+ f
0=2f
0+ k
1(l
1+ l
2+ 2l
3)>=2f
0+ 4k
1l
2, energising spring force is: f
1=f
3+ k
2(l
3+ l
1)>=2f
0+ 2l
2(2k
1+ k
2).
As above analyze known, when power on/off switches, the elastic force independent variable of spring is more, and especially the decrement of upper spring 19 alters a great deal; During lower spring 14 power-off, spring force far exceedes twice sealing load, needs larger electromagnetic force can adhesive, and Electromagnetic Design is very difficult.Otherwise when electromagnetic coil 15 parameter is determined, namely electromagnetic force is fixed, and does not consider other drag losseses, needs rigidity k
1and k
2less, or amount of movement l
2less; And amount of movement associates by force with the performance parameter of solenoid valve, as flow, response time etc.Therefore, k
1, k
2value should be the smaller the better.
In sum, because the rigidity requirement of spring is less, and decrement change comparatively greatly, and for limited electromagnetic force, the designing requirement of spring is higher.
2, in the power-off state, the elastic force of upper spring 19 itself plays negative effect, but during power-off, lower spring 14 amount of movement l
3, and upper spring 19 amount of movement reaches 2l
3, be more unfavorable for that power-off seals.
3, from independent variable, each parameter of power on/off state is all interrelated, Requirement Decomposition to the size of material and performance requirement all very high, cost of production is high, and conforming product rate is low.
4, upper spring 19 amount of movement is large, though spring bottom outside limits by slide block 18, force bearing point often opening pressure head 13 and diaphragm skeleton 12 point of contact, namely at upper spring 19 top, therefore the easy clamping stagnation in top when power on/off switches.

3(suppose both sides symmetry compression, L
3=L
1), now, the reduction length of the first elastic component 140 is: X
0+ L
3, spring force is F
2, the reduction length of the second elastic component 350 is: Y
0-L
3, spring force is F
3.
Suppose, the first elastic component 140 rigidity is K
1, the second elastic component 350 rigidity is K
2, then the first elastic component 140 spring force that is energized is: F
0, spring to break power is: F

Contrast with typical structure and easily see, first elastic component 140 one end limits, at the volley, decrement is efficiently reduced, thus, associate each spring force and all effectively reduce, larger optimization and improvement is all had to Electromagnetic Design and spring design, contribute to power-off sealing, and the switching electrical quantity degree of association is reduced, reduce the control difficulty of material.
It should be noted that, lower valve seat 210 not only for fixing first elastic component 140 one end, and for the straight line motion of first pressure head 130 that leads; Slide block 120 not only plays the intermal force of the second pressure head 150 and dynamic iron core 340, and can play the effect of external constraint to the first elastic component 140.In addition, the first pressure head 130 increases guiding, solves the clamping stagnation of the first elastic component 140 in moving process, effectively improves and produces yield.
More than that better enforcement of the present utility model is illustrated, but the utility model is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent distortion or replacement are all included in the application's claim limited range.
