The data crossed are shown on working panel, and working panel is by box house pressure experienced size in digital form
Display, can judge the seal of container intuitively, and the air tightness detection equipment simple in construction of the present invention makes
With convenient, testing result is the quickest.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technology of the present invention
Means, and can being practiced according to the content of description, below with presently preferred embodiments of the present invention and coordinate attached
After figure describes in detail such as.
Accompanying drawing explanation
Fig. 1 is the structural representation of closed air tightness detection equipment of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is described in further detail.With
Lower embodiment is used for illustrating the present invention, but is not limited to the scope of the present invention.
The specific embodiment of the closed air tightness detection equipment of the present invention is as it is shown in figure 1, include for depositing
The square box 2 of equipment under test and the air inlet pipeline of connection tested container.Wherein, casing 2 include housing and
Cover plate, one end of cover plate is provided with handle, and position corresponding with handle on housing is provided with attacker.At housing
Edge be provided with a circle sealing ring, sealing ring uses resilient transparent rubber to make.When the handle on cover plate
When interlocking with the attacker on housing, casing is air-tight state.Casing 2 center of inside is provided with bracing frame 4, is used for
Placing tested container, bracing frame 4 is welded on the base plate of housing.The coverboard inner face of housing is provided with three
Baroceptor 6, baroceptor 6 is arranged on the working panel outside cover plate by wire connection.Air pressure transmission
Sensor 6 senses the pressure of box house, and the pressure signal detected is transferred to work surface by baroceptor 6
Data processing unit in plate, the data processed are shown on working panel, and working panel is by box house
Pressure experienced size shows in digital form, can judge the seal of container intuitively.
Tested container connects air inlet pipeline by the fast connector being fixed on the sidewall of casing.Air inlet pipeline
Integrated installation is in gas circuit case.Air inlet pipeline is sequentially provided with filter 8, switch 10 along air-flow trend, adjusts
Pressure valve 12 and boost gauge 14.The interface of filter 8 is used for connecting compressed gas source and filtering gas,
Switch is used for opening and closing air inlet pipeline, and pressure regulator valve 12 for being adjusted to the volume of tested container by the air pressure of compressed gas source
Determine air pressure, can read from boost gauge 14 and enter in casing the pressure of gas in testing container.Switch 10
Including press button and air switch, press button controls the on an off of air inlet pipeline power supply, and air switch rises
Overload protective function is to ensure safety, when the pressure in pipeline exceedes certain value, and air switch effect, close
Close air inlet pipeline.
The operation principle of the present invention is as follows:
Open cover plate by handle, testing container is put on bracing frame 4, the interface of testing container is received
In snap joint, then close cover plate, and handle compresses with attacker, and casing keeps air-tight state.Then will enter
The interface of air pipe is received on compressed gas source, opens press button, is adjusted to tested by the air pressure of compressed gas source
The nominal pressure of container, opens the valve of storing compressed air container, compressed air sequentially pass through filter 8,
Pressure regulator valve 12 and boost gauge 14 enter inside container.If container closure is bad, now box house
Pressure increase, baroceptor sense 6 should arrive the pressure increased in casing, and the pressure that then will detect is believed
Number data processing unit being transferred in working panel, the data processed are shown to work by data processing unit
Make on panel, the pressure that current box house increases can be read from working panel, according to the big I of pressure
To judge the seal of container intuitively.If container closure is good, now the pressure of box house will not be sent out
Changing, baroceptor 6 senses less than the pressure increased, and now working panel shows current box house
The pressure increased is zero, shows that container is air tight, and seal is good.
The above is only the preferred embodiment of the present invention, is not limited to the present invention, it is noted that
For those skilled in the art, on the premise of without departing from the technology of the present invention principle, also
Can make some improvement and modification, these improve and modification also should be regarded as protection scope of the present invention.
