[0003] However, the existing packaging container leak detection method has the disadvantage of low detection accuracy. Therefore, the applicant has designed a packaging container leak detection method with high detection accuracy. This high-precision packaging container leak detection method uses positive and negative pressure simultaneously. Act on the inner and outer walls of the packaging container, that is, form a vacuum outside the packaging container, add positive pressure gas into the packaging container at the same time, and then judge whether the packaging container is leaking by observing the change of the vacuum value outside the packaging container

The invention discloses a positive and negative pressure gas distribution device. The positive and negative pressure gas distribution device is characterized in that a shaft type positive pressure gas connector, a disk type negative pressure gas connector and a rotating disk type positive and negative pressure gas distribution device are included; the disk type negative pressure gas connector and the rotating disk type positive and negative pressure gas distribution device are respectively arranged on the shaft type positive pressure gas connector in a sleeved mode, the disk type negative pressure gas connector is placed above the rotating disk type positive and negative pressure gas distribution device, and the disk type negative pressure gas connector is arranged on the shaft type positive pressure gas connector in the mode that the disk type negative pressure gas connector can not rotate; the inner side face of the rotating disk type positive and negative pressure gas distribution device and the outer side face of the shaft type positive pressure gas connector are in sealing rotation fit, and the upper surface of the rotating disk type positive and negative pressure gas distribution device and the lower surface of the disk type negative pressure gas connector are in sealing rotation fit. Thus, the positive and negative pressure gas distribution device can convey positive pressure gas and negative pressure gas at the same time, and accordingly a good basis is laid for high-precision leakage detecting of packaging containers.
Description
technical field [0001] The present invention relates to a gas distribution device, more specifically, the present invention relates to a positive and negative pressure gas distribution device. Background technique [0002] At present, when leak detection is performed on a packaging container, the inside of the packaging container is generally evacuated, and then the change of the vacuum value in the packaging container is observed to determine whether the packaging container is leaking. [0003] However, the existing packaging container leak detection method has the disadvantage of low detection accuracy. Therefore, the applicant has designed a packaging container leak detection method with high detection accuracy. This high-precision packaging container leak detection method uses positive and negative pressure simultaneously. Act on the inner and outer walls of the packaging container, that is, form a vacuum outside the packaging container, and at the same time add positive...
