Test with the sealing tester, pressurize it to 200KPa, keep the pressure under water for 1 minute, and observe whether it leaks or trips; pressurize the air cap to 690kpa, keep the pressure under water for 1 minute, observe whether it leaks, and then increase the pressure to 1207kpa, keep the pressure for 1 minute, and observe the bottle Whether the cover trips.
