Test gas is detected, then proving that battery exemplar is intact.
In 5th step, by the test gas being passed through and nitrogen pressure release, charge valve is then slowly opened by gas and is passed through cabinet
It is interior, case lid is opened when the air pressure in test box is consistent with external atmosphere pressure and takes out tests exemplar, completes testing process.
After battery exemplar completes Work condition analogue air-leakage test, also need through temperature control equipment inside to detection case
Temperature is restored, and opens case lid after temperature recovery and takes out battery exemplar.

Hole extends to inside the detection case, for detecting in detection case with the presence or absence of the test gas.
Test gas and inert gas are sequentially entered in front-end module by two air inlets on front-end module respectively
Primary mixing is carried out in first chamber more evenly for further gas mixing to add between air inlet and first chamber slow
Chamber is rushed, gas is not yet uniformly mixed at this time.The first passage first passage that primary mixed gas passes through intermediate module center
Into intermediate module, secondary mixing is carried out in the second chamber of intermediate module.Have agitating plate in intermediate module, mixed gas into
Rotating Vortex flowing is done under the action of agitating plate after entering intermediate module, effectively increases the gas mixing time, makes mixing more
Uniformly, sufficiently, elementary mixing is uniform for gas at this time.Gas after evenly mixing opens valve block, passes through the online battle array of sieve gas
Column waist hole enters rear module, since valve block is made of thin rubber, so valve block can be opened by only needing the impulse force of very little.Sieve
The online array waist hole of gas is the small irregular waist hole of outer imperial palace of circular array, and in the case where guaranteeing requirement, maximum is dissolved
Port area.The binding face for sieving gas net and valve block is the indent conical surface, increases the contact area of mixed gas and valve block, makes gas
It is easier to open valve block and enters rear module, also further increase outlet open area.Have at sieve gas net indent conical surface outer circle
Heavy platform, valve block sink to completely sieve gas net in, in rear module the indoor gas of third chamber be less susceptible to enter valve block and sieve gas net it
Between gap, more efficiently mixed gas is prevented to flow back, the gas outlet in final rear module by detect pipeline will mix
Gas is closed to convey into the channel of battery exemplar.
The micro opening balanced valve after test, gas slowly in air supply source enter detection case energy, avoid because
Instantaneous pressure variation causes battery exemplar to damage, while the gas in air supply source is the gas of dried and clean, therefore flat in air pressure
During weighing apparatus, environmental sanitation in detection case can be remained.

It is interior.The case where slowly reducing such as the vacuum readings appearance of vacuum meter 11 at this time, illustrating fuel battery inside, there may be larger
Leak source should terminate that testing process, take out battery exemplar 17 and the processing that makes marks.If vacuum meter 11 read be able to maintain it is current true
Then carry out next step within reciprocal of duty cycle 5 minutes or more.
Into detection pipeline 5 detection gas that are passed through be by inert gas and with the matched test gas of leakage alarm
Body, wherein leakage alarm, using warning device corresponding with test gas, discrimination degree can achieve PPM grades, slightly leak
Alarm just will call the police.And test gas and can be hydrogen, argon gas, the gases such as helium.Test gas in detection gas with it is lazy
Property gas mixing ratio be 1:1.Final detection gas, which pass through, enters detection pipeline 5, and forms pressure in detection pipeline 5, this
For sample in the channel of battery exemplar 17 and under the pressure difference effect in detection case 1, detection gas pass through the leak source of battery exemplar 17
Into in detection case 1, leakage alarm detects test gas and issues alarm at this time, to prove that the battery exemplar 17 exists
Leak source.Otherwise at the appointed time such as 30 minutes, leakage alarm is still without test gas is detected, then proving battery exemplar
17 is intact.
In 5th step, by the test gas being passed through and nitrogen pressure release, charge valve is then slowly opened by gas and is passed through cabinet
