With very convenient.In addition, it is not necessary that solenoid valves, which can ensure to produce when due to detection
Under the premise of product full inspection, production efficiency is greatly improved.
In conjunction with shown in Fig. 2, Fig. 3, specific testing principle is as follows:
Because its internal dynamic iron core is considered that solenoid valve is any by suction and electromagnetic force collective effect after electromagnetic valve coil is powered
Installation direction, for ensure any situation can valve opening, electromagnetic force need to overcome the devices gravity such as dynamic core, since dynamic iron core is by frictional force
It is smaller, it is offset subsequently through design margin；Following formula, solenoid valve ability valve opening movement need to be met, and should also have certain
Dynamic response requirement, it is therefore desirable to certain design margin.
FQuiet wicking+ F > P × Δ S+FBullet+G
The electromagnetic force formula F that coil generates when calculating steady operation according to direct current solenoidal magnets formula:
In formula: Φ is working gas gap magnetic flux, unit Wb；B is working gas gap magnetic induction intensity, unit T；μ0For vacuum

In formula: L is around line width, unit mm；D2 is coiling outer diameter, unit mm；D1 is coiling internal diameter, and unit is
mm；D is enamel-cover linear diameter, unit mm.
Therefore coiling outer diameter D 2, winding length are respectively as follows:
But above formula D2 is coiling outer diameter, includes film thickness, and the calculating of actual electromagnetic power should subtract film thickness, therefore practical
Effective coiling length is respectively as follows: with removal film thickness D2 '
Wherein Δ is the value that copper wire diameter d is subtracted comprising film thickness enameled wire average diameter；Such as 0.18 enamel-cover
Line, enameled wire mean outside diameter is 0.204mm, then Δ=0.024, is commonly used shown in solenoid valve line footpath referring in particular to table one:
Table one
| Enamel-cover linear diameter d | Outer diameter | Δ |
| 0.140 | 0.160 | 0.020 |
| 0.160 | 0.182 | 0.022 |
| 0.170 | 0.193 | 0.023 |
| 0.180 | 0.204 | 0.024 |
| 0.200 | 0.226 | 0.026 |
Coiling equivalent internal resistance are as follows:
Coiling equivalent current:
Magnetomotive force E:
So coil generating electromagnetic power F:
In formula: S is magnetic circuit sectional area,Unit is mm2；μ0It is 4 π * for space permeability
10-7Wb/Am；ρ be copper resistivity, 0.01709；D is enamel-cover linear diameter, unit mm；U is coil equivalent voltage, and unit is
V；δ is gas length (iron core stroke), unit mm；D1 is coiling internal diameter, unit mm；D2 ' be remove film thickness around
Line outer diameter, unit mm.
It is (complete in dynamic iron core and static iron core surface after considering that dynamic iron core is magnetized completely by active force and reaction force relationship
When full actuation, that is, δ ≈ 0) know static iron core to dynamic iron core maximum electromagnetic attraction are as follows:
Another because solenoid valve is in addition at air gap, rest part is all made of the good material of magnetic property, and most magnetic are dynamic
Potential drop is that have following formula to the electromagnetic attraction of static iron core at air gap:
NI=∑ (HL) ≈ H0×δ
Wherein H0For magnetic field strength at air gap, unit A/m；δ is gas length (iron core stroke) unit mm；According to following
Two formulas can obtain B0:
It is lost to reduce air gap under same distance, increases magnetic conductivity, be typically chosen tapered surface design；In practical function distance
It (is not attracted completely) when larger, a correction factor a and gas length δ need to be added, for correcting in big air gap due to magnetic flux
Uneven distribution cause error so that static iron core is a Practical Formula to the electromagnetic attraction of dynamic iron core.
B is magnetic induction intensity, unit Gs (1T=10000Gs) in formula；S is magnetic circuit sectional area, unit cm2；δ is air gap
Length (iron core stroke) unit is cm；A is correction factor, according to stroke 0.5-5mm, a empirical value general 3~5；And stroke
Bigger, the value of a is also bigger.
To sum up 5. formula and 7. formula calculate solenoid valve valve opening design margin λ:
Wherein FEnvelopeFor magnetic valve spring valve sealing force, unit N；G is the gravity such as movable iron core of electromagnetic valve, gasket, unit N；P is
Calibrating gas pressure is 5kPa constant；Δ S is gasket area, is π × D2 Gasket/ 4, DGasketFor gasket diameter.
For valve opening state:
According to existing DB44/T402.5-2007 standard, 8. voltage U=0.7U in formulaVolume；When standard design margin λ=0.95
It is preferably to select in~1.10 ranges, solenoid valve is judged to qualified product；As solenoid valve valve opening standard design margin λ > 1.10, deposit
It is excessive in design, lead to solenoid valve high expensive；As standard design margin λ < 0.95, it is insufficient to there is design, it is understood that there may be no
Comply with standard situation.
For maintaining state:
According to existing DB44/T402.5-2007 standard, 8. voltage U=0.33U in formulaVolume；Static iron core of electromagnetic valve is by pressure N
Are as follows:
N=F+FQuiet wicking—(FEnvelope+ k δ+G), judge N > 0.1 for qualification；Wherein k is spring force coefficient.

Press P.Variables D 1, L, d, δ, UVolume、FEnvelope、k、G、DGasket；The no power production test that solenoid valve can be realized, is automatically performed correlometer
It calculates, determines whether qualified product.And when testing, electromagnetic valve coil circle number N, standard design margin λ can display real-time, maintain state N
Value, release conditions N value.
In the present embodiment, production before by input solenoid valve variable (constant is solidificated in device program) coiling internal diameter D1,
Around line width L, enamel-cover linear diameter d, gas length (iron core stroke) δ, voltage rating UVolume, spring valve sealing force FEnvelope, spring system
The gravity G, gasket diameter D gasket such as number k, movable iron core of electromagnetic valve, gasket；After the good electromagnetic valve terminal of grafting, equipment is provided
Now more mature inductance method or hall effect type or magnetic pressure phase-comparison method can obtain electromagnetic valve coil the number of turns N, according to the number of turns N system
It is automatically performed relevant calculation judgement, the no power production test of solenoid valve can be realized, determine whether qualified product；And any ring
Section appearance is unqualified, then product determines unqualified.
