Description
Technical field
The utility model is related to a kind of device of airtight test, especially one kind can be used for detecting all kinds of doors of grain warehouse
The device of the techniques such as window, ventilation opening hole and supporting apparatus air-tightness.
Background technology
With the rapid development and the improvement of people's living standards of science and technology, demand of the market to high-quality grain oil product increases,
To meet the public market demand to high-quality grain oil product, then green grain storage technology is come into being.Controlled atmosphere is to use physics side
Formula desinsection does not use chemical agent, is universally acknowledged green grain storage technology, but it requires pole to the air-tightness in application warehouse
It is high.The supporting apparatus such as gas and the sample strobe device of pest detection requirement in all door and windows, ventilation opening and grain heap for silo
There is higher air-tightness, the air-tightness in whole warehouse cannot be influenced after installation, air-leakage test will be carried out before use.However,
Existing market lacks this air-tightness and detects dedicated unit, and the detection means of each manufacturer differs, and product quality quality is not
Together, the air-tightness and use cost in controlled atmosphere warehouse are seriously affected.Therefore, grain depot technique hole urgently to be resolved hurrily and supporting apparatus
Air-leakage test problem.
Invention content
The purpose of this utility model be exactly for the above-mentioned prior art in the presence of shortcoming and one kind is provided and is used for
Silo technique hole and the dedicated unit of supporting apparatus air-tightness detection.
The purpose of this utility model is realized by following technical measures：
Device of the utility model for the test of utensil air-tightness includes babinet, and there are one gas on the box top
Source interface, a pressure gauge connection and the detection airtight appliance interface of tubulose, one is provided in a vertical wall surface of the babinet
It is a to detect interface for docking airtight utensil.
Furtherly, at least two U-shaped geometrical clamps are provided with for docking airtight utensil detection interface outer wall around described,
By silicone rubber pad 7 and U-shaped geometrical clamp 6 with air-tight manner encapsulation be to dock airtight utensil detect interface cover board or with quilt
The connected adapter flange of utensil is examined, and handwheel is provided on U-shaped geometrical clamp.
Babinet described in the utility model is a rectangular parallelepiped structure.
The utility model is suppressed by gas source interface in babinet when carrying out positive pressure detection；When carrying out detection of negative pressure,
It is evacuated outwardly out of babinet by gas source interface.Pressure gauge connection is directly connected with differential manometer or airtight detector, have positive pressure,
The function of negative pressure and timing.The detection airtight appliance interface 5 of tubulose is used to detect the air-tightness of some small airtight utensils.
The beneficial effects of the utility model are as follows：
1. apparatus structure reasonable design：According to the shape, size and vulnerability level of tested object, different utensils can pass through change
Diameter flange is connected with air tightness detection apparatus, to meet the needs of positive/negative-pressure non-destructive testing.
2. flange docking design is simple：When different utensils are docked with the airtight utensil of detection device detection interface, use is U-shaped
Geometrical clamp fastening means, the structure of adapter flange and making processing capacity when enormously simplifying connection.
3. it is easy to connect tightening operation：Airtight utensil detection interface liner has super thick silicone rubber pad 7, rubber cushion elastic thickness
Much larger than abutted flange in fastening generated deformation range, gluing or diaphragm seal are not necessarily to, on handmade rotary geometrical clamp
Handwheel can clamp flange joint face, so that closed-loop operation is become extremely simple.
4. more than kinds of detecting state facilitates utensil to dock：Due to having interface or instrument on only positive and top surface on detection main box
Device, remaining four face are all plane, when detection can be used it is vertical, placing attitudes, the interfaces such as air source and pressure gauge such as keep flat and also may be used
It is guided to by sebific duct and is connected on one side, observed when facilitating the connection and detection of different utensils and device.
Description of the drawings
Fig. 1 is the structural front view of the utility model.
Fig. 2 is the side view of Fig. 1.
Serial number in figure：1 be babinet, 2 be for dock airtight utensil detection interface, 3 be gas source interface, 4 be that pressure gauge connects
Mouthful, 5 be the airtight appliance interface of detection tubulose, 6 be U-shaped geometrical clamp, 7 be silicone rubber pad, 8 be handwheel, 9 be cover board.
Specific implementation mode
The utility model is below with reference to embodiment（Attached drawing）It is described in further detail：
As shown in Figure 1, 2, the device that the utility model is used for the test of utensil air-tightness includes the babinet of rectangular parallelepiped structure
1, there are one 3, pressure gauge connections 4 of gas source interface and the detection airtight appliance interface 5 of tubulose on the box top, in institute
Stating setting in a vertical wall surface of babinet, there are one for docking airtight utensil detection interface 2.
Furtherly, at least two U-shaped geometrical clamps are provided with for docking airtight utensil detection 2 outer wall of interface around described
6, be encapsulated in air-tight manner by silicone rubber pad 7 and U-shaped geometrical clamp 6 dock airtight utensil detect cover board 9 at interface 2 or with
The connected adapter flange of tested utensil, and handwheel 8 is provided on geometrical clamp 6.
When carrying out airtight detection using the device of the utility model, detecting instrument is connected in advance, opens airtight utensil inspection
Survey interface cover board 9, by different utensils by adapter flange and airtight utensil detection interface connect, small utensil and tubulose it is airtight
Appliance interface is connected, and pressure-resistant object is detected with positive pressure, rapid wear object detection of negative pressure.In preparations such as the closed processes for carrying out device
After work, unlatching is suppressed or air-extractor, higher than closing air machinery immediately after rated pressure, timing when reaching rated pressure
Pressure in device record air tightness detection apparatus decays to the time of half from rated pressure, and the pressure of as tested utensil partly declines
Phase.Entire detection process is simple and direct, quick.
In warehouse construction, the technique hole often opened and closed to some in production in advance and supporting apparatus is needed to carry out air-tightness
Test will not form air leak position to ensure these utensils to be mounted on warehouse.In characterization processes hole and the gas of supporting apparatus
When close property, the cover board 9 of airtight utensil detection interface is first opened, by the techniques such as the ventilation opening in warehouse, door and window hole and supporting apparatus
Interface 2 is detected by adapter flange with the airtight utensil of the docking of detection device to be connected, the gas detection terminal of grain inspection system
And sample strobe device is then connected with the airtight appliance interface of detection tubulose 5, is then turned on and suppresses equipment towards filling in air tightness detection apparatus
Gas or unlatching vacuum equipment are evacuated out of air tightness detection apparatus, and after reaching predetermined pressure index, closing is suppressed or air-extractor, pressure
Power meter shows that the pressure change in detection device, timer record detection device decay to the time of half from rated pressure, uses
Foaming agent inspection is detected the air leakage point of object, and the final metrics evaluation with pressure half-life period is detected the quality of object air-tightness, complete
At the task of the airtight detection of utensil.
