The danger causing human body, avoids the trouble of manual read's pressure force value simultaneously.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of high-voltage testing device of the prior art.
Fig. 2 is the schematic diagram of the high pressure test device for air tightness of this utility model preferred embodiment.
Detailed description of the invention
Provide this utility model preferred embodiment below in conjunction with the accompanying drawings, to describe the technical solution of the utility model in detail,
But the most therefore this utility model is limited among described scope of embodiments.
As in figure 2 it is shown, the present embodiment provides a kind of high pressure test device for air tightness, it includes test source of the gas 1, pump gas
Source 2, one booster pump 3, controller 4 such as computer, inflator seal 5,1 second pressure transducer 6 and a unloading port 7.
Wherein, this inflator seal 5 is internal to be used for placing test specimen 10, and the outlet of this booster pump 3 is by one first pipeline 8
It is connected with the entrance of this booster pump 3, the outlet of this booster pump 3 entrance phase by a second pipe 9 with this test specimen 10
Connecting, the entrance of this test specimen 10 is by this second pipe 9 and a valve (see the electromagnetic valve 2 in Fig. 2 and hand-operated valve 4) and is somebody's turn to do
Unloading port 7 is connected, and this second pipe 9 is provided with one first pressure transducer 11, and this test source of the gas 1 is by the 3rd pipeline 12
It is connected with the inside of this inflator seal 5.
The test test specimen process whether leaked gas be specifically described below:
Opening hand-operated valve 2 and 3 and this booster pump 3, the test gas transmission in this test source of the gas 1 is to this booster pump 3, this control
Device 4 processed controls this pump source of the gas 2 and drives this booster pump 3 to this test gas boosting, and this test gas transmission extremely should by this booster pump 3
The inside of test specimen 10, meanwhile, the test gas in this booster pump 3 exit enters this booster pump 3 by this first pipeline 8
Entrance, reaches secondary booster, shortens pressurization time.
This first pressure transducer 11 constantly detects the force value in this second pipe 9, and the force value that will detect
Transmit to controller 4, the force value that this first pressure transducer 11 is constantly transmitted by this controller 4 and this controller 4
The setting threshold value of storage compares, when the force value that the transmission of this first pressure transducer 11 comes is less than this setting threshold value, and should
Controller 4 controls this pump source of the gas 2 and drives this booster pump 3 to this test gas boosting until the transmission of this first pressure transducer 11 comes
Force value reach this setting threshold value, now, pressurization terminates, and hereafter in test process, this booster pump 3 remains turned-off, manually
Valve 3 is also switched off.
Then, the pressure in this inflator seal 5 in such as 30 minutes in this second pressure transducer 6 tests a time period
Value, and those force value are transmitted to this controller 4.This controller 4 judges in this time period that whether later moment in time receives
The force value that force value always receives more than previous moment, if then sending the information of this test specimen gas leakage, such as
Sending a warning message or voice messaging, to allow staff recognize, this test specimen leaks gas.
After test terminates, needing to release the test gas in this test specimen 10, specifically, this controller 4 controls electricity
Magnet valve 2 is opened, hand-operated valve 3 is opened, the test gas in this test specimen 10 by this second pipe 9 and this electromagnetic valve 2 from this
Unloading port 7 flows out.
Although the foregoing describing detailed description of the invention of the present utility model, it will be appreciated by those of skill in the art that
These are merely illustrative of, and protection domain of the present utility model is defined by the appended claims.Those skilled in the art
