Opening liquid supply pressure mechanism, after inlet valve has liquid to flow out, inlet valve closes, and inlet valve pressure adds to inlet valve liquid threshold pression test value；After voltage stabilizing keeps, continuance test force value, judge according to deviation data: deviation data is less than the inlet valve liquid lower limit set amount of deflection, judge inlet valve liquid threshold pression test passes, deviation data is more than the inlet valve liquid lower limit set amount of deflection, it is determined that inlet valve gas tightness is defective；It is forced into inlet valve liquid pressure upper limit test value；After voltage stabilizing keeps, continuance test force value, judge according to deviation data: deviation data sets the amount of deflection less than the inlet valve liquid upper limit, it is determined that inlet valve fluid tightness is qualified；Deviation data sets the amount of deflection more than the inlet valve liquid upper limit, it is determined that inlet valve fluid tightness is defective；It is decompressed to normal pressure；Closing liquid supply pressure mechanism；The fluid tightness test operation of inlet valve completes；
D), the fluid tightness test of sealing member:
Sealing member is arranged on upper module；Upper module mounting seat moves down, and sealing member clamps with lower module；Inlet valve is opened, and opens liquid provider switch, and after sealing member has liquid to flow out, sealing member closes, and seal pressure adds to sealing member liquid the first Stress testing loss；After voltage stabilizing keeps, continuance test force value, judge according to deviation data: deviation data sets the amount of deflection less than sealing member liquid first, judge that sealing member liquid the first stress test is qualified, deviation data sets the amount of deflection more than sealing member liquid first, it is determined that sealing member fluid tightness is defective；Being forced into sealing member liquid the second Stress testing loss, wherein sealing member liquid the second Stress testing loss is more than sealing member liquid the first Stress testing loss；After voltage stabilizing keeps, continuance test force value, judge according to deviation data: deviation data sets the amount of deflection less than sealing member liquid second, it is determined that sealing member fluid tightness is qualified；Deviation data sets the amount of deflection more than sealing member liquid second, it is determined that sealing member fluid tightness is defective；It is decompressed to normal pressure；Closing liquid supply pressure mechanism；Take off sealing member, carry out automatic sorting operation；Sort operation: qualified, enters certified products district；Defective, enter defective district；The fluid tightness test operation of sealing member completes.
