Based on above-described embodiment, in the mode of alternatively possible realization, what operating platform can be received with real-time display device
Air pressure and detection flows are detected, and are more than preset flow threshold value and/or real-time reception in the detection flows for detecting real-time reception
Detection air pressure be more than preset pressure threshold value when, alerted to prompt staff, it is ensured that air tightness detection apparatus can be safe
Operation.
It should be understood by those skilled in the art that, pressure sensor may also be arranged at the venthole of the first sealing pallet.
Referring to FIG. 2, in one embodiment of the invention, the detection control mechanism 101 further comprises：Second snorkel
Road 1016 and second solenoid valve 1017；Wherein,
The first end of second vent line 1016 is connected with the external compressor, second vent line
1016 second end is correspondingly connected with the compression executing agency 102；
The second solenoid valve 1017 is arranged on second vent line 1016；
The operating platform 1015 is further used for controlling the unlatching of the second solenoid valve 1017 so that external is described
Compressor can drive the second high pressure gas to enter second vent line 1016 and act on the compression executing agency 102,
The compression executing agency 102 can drive the first sealing pallet 103 towards institute under the action of second high pressure gas
It states target second and seals the movement of pallet 105.
In above-described embodiment, after operating platform controls second solenoid valve unlatching, the high pressure gas of compressor output can lead to
Cross the second vent line and act on and compress executing agency, compress executing agency can then be driven under the action of high pressure gas it is first close
It seals pallet and seals tray motion towards second, so that target second seals pallet and the first sealing pallet respectively to be detected
The lower port and upper port of people's air defense gas-particulate filter are sealed, at this point, the first sealing pallet is filtered absorption of to people's air defense to be detected
After the sealing air pressure that the upper end of device applies inputs high pressure gas slightly larger than input to the second vent line in the second vent line
First air pressure；In subsequent process, driven compressor high pressure gas enters people's air defense to be detected by the first vent line and venthole
After inside gas-particulate filter, the second air pressure in people's air defense gas-particulate filter to be detected gradually rises, when second gradually risen
When air pressure is more than sealing air pressure, the second air pressure can then overcome sealing air pressure to compress executing agency to push so that compress execution machine
Structure and the first sealing pallet counter motion, so that the high pressure gas in people's air defense gas-particulate filter to be detected can pass through the upper end
Mouth discharge, avoids the second air pressure in people's air defense gas-particulate filter to be detected excessive and brings security threat.
Specifically, figure Fig. 2 is please referred to, in one embodiment of the invention, the compression executing agency 102, including：Supporting table
Frame 1021, cylinder 1022 and piston 1023；Wherein,

Sealing pallet 103 is fixedly connected；
The external compressor can drive the second high pressure gas to enter the gas by second vent line 1016
Cylinder 1022, the high pressure gas into the cylinder 1022 can drive the piston 1023, and the first sealing pallet 103 can be in institute
It states and seals the movement of pallet 105 towards the target second under the drive of piston 1023.
In above-described embodiment, compressor can drive high pressure gas to enter cylinder by the second vent line, into cylinder
High pressure gas can drive piston towards target second seal tray motion, first sealing pallet then can under the drive of piston direction
Target second seals tray motion, so that target second seals pallet and the first sealing pallet respectively to people's air defense to be detected
The lower port and upper port for filtering absorber are sealed；When the second air pressure in people's air defense gas-particulate filter to be detected is excessive, wait for
High pressure gas inside detection people's air defense gas-particulate filter can then push the first sealing pallet and piston reverses direction to move, so that waiting for
High pressure gas in detection people's air defense gas-particulate filter can be discharged by port thereon, be avoided in people's air defense gas-particulate filter to be detected
Second air pressure is excessive and brings security threat.
Referring to FIG. 2, support stand can be specifically "door" type holder, two support posts of portal trestle can be installed
On rolling dress transmission mechanism, and positioned at the both sides of rolling dress transmission mechanism.Support stand specifically can be by channel steel and/or stainless steel
At.
Based on above-described embodiment, in a kind of mode in the cards, which can also include that setting is supporting
Detection module (for example, infrared detecting device or to penetrating pipe) on rack, detection module can be realized under the first sealing pallet
The object of side is detected, and if only if detecting below the first sealing pallet there are when people's air defense gas-particulate filter to be detected,
Trigger signal is sent to operating platform, operating platform then can perform corresponding control program, control second solenoid valve, first successively
Solenoid valve is opened, and realization detects the air-tightness of people's air defense gas-particulate filter automatically.
It should be understood by those skilled in the art that, rolling dress transmission mechanism can be specifically rolling dress assembly line, can also be class
Like other transmission mechanisms of conveyer belt, it is only necessary to ensure that it can install one or more second and seal pallet, and can drive
Each second sealing pallet carries out reciprocal in the lower section of designated position and the first sealing pallet.
To realize after completing to a people's air defense gas-particulate filter progress air-leakage test to be detected so that the first sealing
