[0034] Workflow: During the connection of the first pipe section 1 and the second pipe section 2, to ensure the high pressure resistance and corrosion resistance after the connection, the first pipe section 1 is first inserted from the upper end of the negative pressure assembly 4. The first pipe section 1 passes through the inner shell 41 and the collar plate 45. When the bottom end of the first pipe section 1 is in contact with the top of the central plate 31, the inner side of the lower end of the first pipe section 1 is at the upper end of the connecting nozzle 35. The first pipe section 1 is sealed between the PTFE sealing ring 36 and the connecting nozzle 35. Following the same principle, the second pipe section 2 is inserted from the lower end of the negative pressure assembly 4 until the upper end of the second pipe section 2 is in contact with the bottom end of the central plate 31. Simultaneously, the second pipe section... After the inner side of the upper end of pipe 2 is sealed between the PTFE sealing ring 36 and the connecting nozzle 35, the outer side of the first section of pipe 1 is sealed between the first rubber ring 42 and the inner shell 41, and the outer side of the first section of pipe 1 is sealed between the second rubber ring 46 and the collar plate 45. The sealing structure of the second section of pipe 2 is the same as that of the first section of pipe 1. After rotating multiple plastic bolts 5, the plastic bolts 5 are made to fit against the outer side of the first section of pipe 1 and the outer side of the plastic bolts 5 against the outer side of the second section of pipe 2.

The one-way valve cylinder 3 is inserted through the air nozzle of the air pump. Inside 4, under negative pressure, the one-way valve inside the one-way valve cylinder 34 opens, and the air inside the sealing airbag 43 is drawn out.

It then enters the one-way valve cylinder 34 through the annular through hole 33 and is finally drawn out. The air being drawn out of the sealing airbag 43 causes the sealing airbag 43 to deform. The inner sides of the two sealing airbags 43 are in close contact with the outer sides of the first section of pipe 1 and the second section of pipe 2. Strong friction is generated between the first section of pipe 1 and the second section of pipe 2. When the air inside the air storage cylinder 37 is extracted, the two hollow guide rods 38 move towards each other.

The device improves the accuracy of the connection when connecting the first section of pipe 1 and the second section of pipe 2, and at the same time improves the stability of the connection. It can ensure the high pressure resistance and corrosion resistance of the first section of pipe 1 and the second section of pipe 2 after the connection.
