Embodiment Construction

[0033] The airtightness detection method of the present invention is to firstly put the container to be tested into the detection device, and make it connected with the inflatable part and then fix it in the detection device; then, seal the detection device, and inject water to retain one and the pressure detection part Then the compressed air is injected into the detected container through the inflatable part; the pressure of the air chamber is detected by the pressure detection part; if the pressure increases, the detected container leaks; if it does not increase, it means that it is detected The airtightness of the detection container is good. The air chamber pressure signal detected by the aforementioned pressure detection part can be transmitted to the control part; if the signal transmitted to the control part indicates that the detected container is leaking, the camera part on the detection device can be controlled to take pictures of the leaking part of the detected con...

Abstract

The invention relates to container air tightness check technical field, in particular to a container air tightness check method and a relative device. The invention arranges an object container in a check device, fills water into the check device, aerates the container, and checks the pressure of an air room in the check device to check the air tightness of the object container. The upper cover of a water cylinder of the check device is arranged with a press plate and a water inlet, the inner side of the press plate opposite the water cylinder is arranged with a clamping lever and a clamper, one end of the clamping lever is connected with a cylinder outside the press plate, the clamper is communicated with an air inlet outside the press plate, the air inlet is communicated with an air pot, the press plate is arranged with a water level sensor which part exposed outside the press plate is connected with a pressure sensor, and the pressure sensor is connected with a control part. The inventive check method has high check speed, high automation, and wide application on container air tightness check of bond type purifier.

Description

technical field [0001] The invention relates to the technical field of container airtightness detection, in particular to a container airtightness detection method and a device thereof. Background technique [0002] In terms of container air tightness testing methods, the usual testing methods include foam method, water immersion method, air differential pressure method, special gas method, etc. Among them, the degree of automation of the water immersion method is low, and the detection speed of small leaks by the air differential pressure method is slow. Contents of the invention [0003] One of the technical problems solved by the present invention is to provide a method that overcomes the shortcomings of the water immersion method and the air differential pressure method, and can quickly and automatically detect the airtightness of the container. [0004] The second technical problem to be solved by the present invention is to provide a device for automatically and qui...
