[0027] Example 1

[0028] like Figure 1 , Figure 2 , Figure 4As shown, the device includes a compressor pipeline 1 and a support ring 2, the support ring 2 is fixedly arranged on the right side of the compressor pipeline 1, a mounting sleeve 3 is fixedly arranged on the right side of the outside of the support ring 2, an intake pipe 4 arranged on the right side of the compressor pipeline 1 is threadedly sleeved on the mounting sleeve 3, a sealing assembly 5 is arranged on the right side of the compressor pipeline 1, the sealing assembly 5 includes a first air cushion 501 fixedly arranged around the right side of the compressor pipeline 1, a slip ring 502 is sleeved on the outside of the mounting sleeve 3, and the outer wall of the slip ring 502 is slidingly connected to the inner wall of the compressor pipeline 1, a second air cushion 503 fixedly arranged around the left side of the slip ring 502 is sleeved on the outside of the mounting sleeve 3, the left side of the second air cushion 503 is fixedly connected to the right side of the support ring 2, a connecting pipe 504 is fixedly penetrated at the upper and lower ends of the left side of the second air cushion 503, and the end of the connecting pipe 504 away from the second air cushion 503 is fixedly penetrated through the support ring 2, the compressor pipeline 1 and the first air cushion 501 in sequence.

[0029] The staff first inserts the intake pipe 4 into the right side of the compressor pipeline 1, so that the intake pipe 4 covers the installation sleeve 3, and then rotates the intake pipe 4 forward to threadably connect the intake pipe 4 with the installation sleeve 3. During the threaded connection process of the intake pipe 4 and the installation sleeve 3, the intake pipe 4 squeezes the slip ring 502 to drive the second air cushion 503 to be compressed. The gas in the compressed second air cushion 503 is discharged into the first air cushion 501 through the connecting pipe 504, and the first air cushion 501 expands. The expanded first air cushion 501 clamps the outside of the intake pipe 4 to seal the area between the inner wall of the compressor pipeline 1 and the outer wall of the intake pipe 4.

[0030] Example 2

[0031] like Figure 2 , Figure 3 , Figure 5As shown, the outer fixed sleeve of the intake pipe 4 is provided with a connecting sleeve 7, and the connecting sleeve 7 is threadedly sleeved on the outside of the compressor pipeline 1. The center of the circular ring formed by the first air cushion 501, the slip ring 502 and the second air cushion 503 is concentric with the center of the mounting sleeve 3. A plurality of first springs 6 are fixedly arranged around the inside of the second air cushion 503. The center of the circular ring formed by the plurality of first springs 6 is concentric with the center of the mounting sleeve 3. A plurality of mounting holes 8 are integrally arranged around the right side of the connecting sleeve 7. The clearance hole 9 arranged outside the mounting hole 8 is integrally connected with the connecting sleeve 7. A mounting block 10 is fixedly arranged inside the mounting hole 8. The exhaust holes 11 integrally arranged on the left and right sides of the mounting block 10 are through-hole designed, a second spring 12 is fixedly provided at the middle end of the outer side of the mounting block 10, a rubber slider 13 is fixedly provided at the end of the second spring 12 away from the mounting block 10, the slider 13 is slidably connected to the mounting hole 8, an indicator pin 14 is fixedly provided on the outer side of the slider 13, and the indicator pin 14 and the clearance hole 9 correspond to each other one by one, the center of the circular ring formed by several mounting holes 8 and several clearance holes 9 is concentric with the center of the intake pipe 4, the inner diameter of the slip ring 502 is consistent with the outer diameter of the mounting sleeve 3, and the outer diameter of the slip ring 502 is consistent with the inner diameter of the compressor pipeline 1.

[0032] According to the operation method in Example 1, when the second air cushion 503 is compressed, the first spring 6 is in a deformed state. When the air intake pipe 4 is threadedly connected to the mounting sleeve 3, the air intake pipe 4 drives the connecting sleeve 7 to be threadedly connected to the outside of the compressor pipe 1 until the left side of the inside of the connecting sleeve 7 is tightly fitted with the right side of the outside of the compressor pipe 1. At this time, it means that the sealing state of the first air cushion 501 after expansion has met the requirements. The staff then transports the gas from the air intake pipe 4 through the support ring 2 and the compressor pipe 1 to the inside of the compressor. If the left side of the inside of the connecting sleeve 7 and the right side of the outside of the compressor pipe 1 are not in close contact with each other, the air intake pipe 4 will be in a state of being sealed. When the air intake pipe 4 and the compressor pipe 1 are in close contact, that is, the expansion state of the first air cushion 501 is not up to standard, air leakage will occur in the area where the air intake pipe 4 and the compressor pipe 1 are in contact with each other, and the leaked gas will push the slider 13 through the mounting hole 8 through the exhaust hole 11, so that the slider 13 drives the indicator pin 14 to move out of the clearance hole 9, and the second spring 12 is deformed. When the staff sees that the indicator pin 14 moves out of the clearance hole 9, it can be known that the threaded connection between the air intake pipe 4 and the mounting sleeve 3 is not tightened. The staff will continue to rotate the air intake pipe 4 to ensure the stability of the first air cushion 501 after expansion and sealing. When the air leakage detection is completed, the second spring 12 is used to make the slider 13 and the indicator pin 14 move into the mounting hole 8. When the staff separates the air inlet pipe 4 from the mounting sleeve 3, the second air cushion 503 together with the slip ring 502 are reset through the rebound force of the first spring 6, and then the gas in the first air cushion 501 flows back into the second air cushion 503 through the connecting pipe 504, that is, the first air cushion 501 is compressed.
