If first difference is less than or equal to the 4th preset value, determine that the conservator capsule is air tight；
If first difference is greater than the 4th preset value, the conservator capsule gas leakage is determined.
Specifically, due to the influence of objective factor, the pressure in conservator capsule can generate minor change, the small change of pressure
Change should not be taken as conservator capsule whether the judgment criteria of gas leakage, the 4th preset value here is exactly the restriction for allowing pressure change
Value, the 4th preset value can be set according to the specific production technology of conservator capsule, making material etc..If the first difference is small
In or equal to the 4th preset value, show that the pressure change of conservator capsule is in normal pressure range, therefore, it is determined that conservator
Capsule is air tight, and leakproofness is good；Similarly, if the first difference is greater than the 4th preset value, show the pressure change of conservator capsule
It is abnormal, therefore, it is determined that conservator capsule gas leakage.
Here, revised first difference should also meet it is above-mentioned judge conservator capsule whether the detailed process of gas leakage.
