Abstract
The purpose of this utility model is that disclosing a kind of vacuum tank helium detection device, it includes that a helium takes device and support base away, it includes a bottom plate that the helium, which takes device away, the bottom plate lower part is provided with a connecting column, the connecting column is connected by bottom plate with the support base, and the connecting hole between the support base and the mating surface of the bottom plate is provided with air slot；Compared with prior art, when workpiece has slight leakage, the gas inside vacuum tank can be emptied by connecting column, can more accurately detect whether workpiece leaks, to realize the effect for lowering background, be will not influence background, realized the purpose of this utility model.
Description
Technical field
The utility model relates to a kind of helium detection device, in particular to a kind of vacuum tank helium suitable for helium inspection equipment
Detection device.
Background technique
With the development of economy, environmental issue has become an important topic of contemporary society, the leakage of many products
Increasingly serious one of the reason of environmental issue is also become, leak detection must carry out in this case.
Helium inspection has become main since the coverage area that it can accurately measure product leak rate and detection is wider
Detection method.
Since China's helium inspection technology is also immature, existing helium inspection equipment when detecting, and is paid no attention to due to various problems
Think.
It is accordingly required in particular to which a kind of vacuum tank helium detection device, above-mentioned existing to solve the problems, such as.
Utility model content
The purpose of this utility model is to provide a kind of vacuum tank helium detection devices in view of the deficiencies of the prior art can
The background of equipment, can more accurately detect whether workpiece leaks when preferably reducing helium inspection.
The technical issues of the utility model is solved can be realized using following technical scheme:
A kind of vacuum tank helium detection device, which is characterized in that it includes that a helium takes device and support base, the helium away
It includes a bottom plate that gas, which takes device away, and the bottom plate lower part is provided with a connecting column, and the connecting column passes through bottom plate and the support
Seat is connected, and the connecting hole between the support base and the mating surface of the vacuum tank is provided with air slot.
In one embodiment of the utility model, the connecting column passes through connector on bottom plate and the support base phase
Connection.
In one embodiment of the utility model, it is provided with plug and spacer in the support base, realizes to workpiece
Sealing.
In one embodiment of the utility model, the connecting column is connected with the hole of the base plate interior, the bottom
The hole of intralamellar part with inside the support base plug and spacer be connected.
The vacuum tank helium detection device of the utility model, compared with prior art, when workpiece has slight leakage, very
Gas inside empty van can be emptied by connecting column, can more accurately detect whether workpiece leaks, to realize attenuating background
Effect, will not influence background, realize the purpose of this utility model.
The characteristics of the utility model, sees the detailed description of the drawings of the present case and following preferable embodiment and obtains clear
Ground understands.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the vacuum tank helium detection device of the utility model；
Fig. 2 is the structural schematic diagram of the support base of the utility model.
In figure, 1- connecting column, 2- plug, 3- spacer, 4- workpiece, 5- support base, 6- bottom plate, 7- vacuum tank, 8- air slot.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Embodiment
As depicted in figs. 1 and 2, the vacuum tank helium detection device of the utility model, it include a helium take away device and
Support base 5, it includes a bottom plate 6 that the helium, which takes device away, and 6 lower part of bottom plate is provided with a connecting column 1, and connecting column 1 passes through bottom plate 6
It is connected with support base 5, the connecting hole between support base 5 and the mating surface of vacuum tank 7 is provided with air slot 8.
The effect of air slot 8 is that the gas when evacuating inside vacuum tank 7 can be extracted by air slot 8, thus real
Now lower the effect of background.
In the present embodiment, connecting column 1 is connected by the connector on bottom plate 6 with support base 5.
In the present embodiment, it is provided with plug 2 and spacer 3 in support base 5, realizes the sealing to workpiece 4.Workpiece 4 has gently
When micro- leakage, it can be emptied by connecting column 1, will not influence background.
In the present embodiment, connecting column 1 is connected with the hole inside bottom plate 6, inside the hole inside bottom plate 6 and support base 5
Plug 2 be connected with spacer 3.
The working principle of the vacuum tank helium detection device of the utility model is as follows:
Connecting column 1 is connected with the hole inside bottom plate 6, the hole inside bottom plate 6 and the plug 2 and spacer 3 inside support base 5
Sealing to 4 bottom of workpiece is realized in connection, and 4 bottom of workpiece can also be emptied by connecting column 1 if there is slight leakage,
Internal system, which will not be leaked into, influences background.
All connecting holes between 7 mating surface of support base 5 and vacuum tank are provided with air slot 8；When vacuumizing, internal system
Air can be pumped to exterior by air slot 8, to realize vacuum tank helium leak check, reduce the effect of helium background.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention, the utility model
Claimed range is defined by the appending claims and its equivalent thereof.
