Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
The first embodiment is as follows:
as shown in fig. 1, a snap-on leak test device for a gas-filled sealed container, comprising: bottom plate 1, buckle closure 2 and carbon dioxide sensor 3.
The buckle cover 2 is connected with the bottom plate 1 in a sealing way and forms an accommodating cavity for accommodating the inflatable sealed container 4 with the bottom plate 1; the carbon dioxide sensor 3 is arranged in the accommodating cavity, the carbon dioxide sensor 3 is in communication connection with an upper computer, and the upper computer is used for storing, analyzing and processing data acquired by the carbon dioxide sensor 3; the gas in the gas-filled sealed container 4 is a gas not containing carbon dioxide or a gas having a carbon dioxide concentration less than a set value; the gas in the accommodating cavity is the atmosphere in the current environment; the gas pressure in the gas-filled sealed container 4 is greater than the atmospheric pressure in the containing chamber.
The gas with the concentration of the carbon dioxide less than the set value means that the concentration of the carbon dioxide in the inflatable sealed container is less than a set value, and the range of the set value generally means 1% -3% of the concentration of the carbon dioxide in the atmosphere.
In the embodiment, the buckle cover 2 is detachably connected with the bottom plate 1 in a sealing way; before use, the buckle cover 2 is separated from the bottom plate 1, the inflatable sealed container 4 is placed on a designated position of the bottom plate 1, and then the buckle cover 2 is connected with the bottom plate 1 in a sealing mode; after the detection is finished, the buckle cover 2 is separated from the bottom plate 1, and the inflatable sealed container 4 is taken away for the next detection. Or the buckle cover 2 is in non-detachable sealing connection with the bottom plate 1; but a passage is provided on the buckle closure 2 or the base plate 1 to allow the air-tight container 4 to enter the receiving cavity and the passage can be sealed before the detection starts.
Example two:
based on the buckle closure type leakage detection device for the inflatable sealed container provided by the first embodiment, the present embodiment provides a buckle closure type leakage detection method for the inflatable sealed container.
Step 1: before the detection is started, the accommodating cavity is in a non-sealing state, and the inside and the outside of the accommodating cavity are communicated; and covering the sealed container filled with the gas which does not contain the carbon dioxide component and exceeds the ambient atmospheric pressure (namely, putting the inflatable sealed container into the accommodating cavity), wherein the atmosphere is outside the covering, and the inflatable sealed container filled with the gas which does not contain the carbon dioxide component and exceeds the ambient atmospheric pressure is inside the covering.
Step 2: after the detection is started, the accommodating cavity is in a sealed state, namely, the gas in the accommodating cavity is not communicated with the atmosphere outside the accommodating cavity; and collecting and recording the concentration of the carbon dioxide in the accommodating cavity according to a set time interval.
And 3, step 3: according to the change of the concentration of the carbon dioxide in the containing cavity along with the time, whether the inflatable sealing container leaks is judged, and the method specifically comprises the following steps:
when the concentration of the carbon dioxide in the accommodating cavity does not change along with the change of time, judging that the inflatable sealed container does not leak;
when the concentration of the carbon dioxide in the accommodating cavity is reduced along with the change of time, judging that the inflatable sealed container leaks; and the larger the rate of change in the decrease in the concentration of carbon dioxide in the accommodating chamber with time, the higher the leak rate of the gas-filled sealed container.
Typically, the carbon dioxide content of the atmosphere is about 320-450ppm. When the gas in the gas-filled sealed container does not contain carbon dioxide or the content of the carbon dioxide is far lower than the content of the carbon dioxide in the atmosphere (for example, the concentration of the carbon dioxide in the gas-filled sealed container is lower than 3 percent of the concentration of the carbon dioxide in the atmosphere), whether the gas-filled sealed container leaks or not can be accurately detected by using the method.
The invention overcomes the defect that the prior art needs to use the gas component sensor in the inflatable sealed container to detect the leakage of the leakage component, can detect the leakage or the sealing state of the sealed container which is filled with the gas which does not contain the carbon dioxide component and exceeds the ambient atmospheric pressure by combining the most commonly used carbon dioxide gas component sensor and the form of a buckle cover method under the condition of not influencing the sealed container, and has wide use value in practice.
Example three:
based on the first embodiment and the second embodiment, the present embodiment provides a buckle-cover type leakage detection system for an inflatable sealed container, including the buckle-cover type leakage detection device for an inflatable sealed container in the first embodiment, further including:
the data acquisition module is used for acquiring and recording the concentration of the carbon dioxide in the accommodating cavity according to a set time interval;
and the leakage early warning module is used for judging whether the inflatable sealed container leaks or not according to the change of the concentration of the carbon dioxide in the accommodating cavity along with the time.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
