[0042] The first clamping member 5 is formed with an annular first clamping groove 6, and the first flat plate gasket 4 is partially accommodated in the first clamping groove 6. The first clamping member 5 is fixedly connected to the first sleeve 2 through a clamp 17, and the first clamping member 5 is used to fix the first flat plate gasket 4 to the first limiting groove 3. The end of the first clamping member 5 away from the first flat plate gasket 4 is provided with an external thread.

[0043] As a specific preferred embodiment, the wall-penetrating closed isolation device further includes:

[0044] A second sleeve 8, a second connecting plate 13 is provided on the second sleeve 8, the second connecting plate 13 is connected to the target color steel 1 through glass glue, the second sleeve 8 is threadedly connected to the end of the first sleeve 2 away from the first flat gasket 4; a second limiting groove 9 is provided at the end of the second sleeve 8 away from the first sleeve 2, and the inner diameter of the second limiting groove 9 is larger than the inner diameter of the second sleeve 8; a second flat gasket 10 is accommodated in the second limiting groove 9, and the diameter of the second flat gasket 10 is larger than the inner diameter of the second sleeve 8 and smaller than the inner diameter of the second limiting groove 9, and the second flat gasket 10 is also provided with through holes, and the number and position of the through holes are consistent with those of the first flat gasket 4; a second clamping piece 11, the second clamping piece 11 is fixedly connected to the second sleeve 8 through a clamp 17, the second clamping piece 11 is used to fix the second flat gasket 10 to the second limiting groove 9, and the end of the second clamping piece 11 away from the second flat gasket 10 is provided with an external thread. The second clamping member forms a second clamping groove 12 , and the second flat plate sealing gasket 10 is partially accommodated in the second clamping groove 12 .

[0045] As a specific preferred embodiment, the first sleeve 2 is provided with an air inlet 14, and the air inlet 14 is used to pass pure compressed air; the second sleeve 8 is provided with an air outlet 15, and the air outlet 15 is used to discharge impurities and moisture in the first sleeve 2 and the second sleeve 8 under the action of compressed air. In order to ensure that impurities and moisture will not be retained in the first sleeve 2 and the second sleeve 8, the opening of the air outlet 15 is vertically downward.

[0046] As a specific preferred embodiment, when the device is not in use, in order to prevent airflows between rooms of different levels from being connected to each other, a dedicated blind plate 16 is threadedly connected to the first clamping member 5 and the second clamping member 11 .

[0049] During installation, two people need to cooperate on both sides of the wall. First, insert the internal threaded sleeve; the installer on the other side holds the external threaded sleeve and screws it into the internal threaded sleeve. When the width between the first connecting plate 7 and the second connecting plate 13 is basically equal to the thickness of the color steel plate, the high clean level area side (or non-toxic area) should be used as the air inlet side, the gas inlet is vertically upward, and the other side is tightened downward as much as possible. A slight deviation will not have any effect.

[0050] After confirming the fastening, use glass glue to seal the first connecting plate 7 and the second connecting plate 13 around. After 3 hours, it can be cleaned. After cleaning, the compressed air pipeline and compressed air filter can be connected to the high clean level area side (or non-toxic area side); the compressed air discharge pipeline and filter can be connected to the air outlet 15 on the other side.
