The utility model provides an assembly degree of difficulty between takeover can be reduced to gas distribution sealing nozzle convenient to dismouting. The assembly efficiency of the gas-liquid separator is improved. Fig. 1 is a schematic structural diagram of a sealing joint pipe in the embodiment, and fig. 2 is an exploded view of the sealing joint pipe, and as shown in the drawing, in the embodiment, the sealing joint pipe includes: a nozzle body, a sealing sleeve 4, a squeezing sleeve 5 and an adjusting sleeve 6.

The connecting pipe body comprises a splicing section 1, a limiting section 2 and a conveying section 3 which are connected in sequence, the outer diameter of the limiting section 2 is larger than that of the splicing section 1, a sealing sleeve 4 is sleeved on the splicing section 1, and a sealing groove used for accommodating a connecting pipe to be assembled is formed in the end face, far away from the limiting section 2, of the sealing sleeve 4. When assembling the two connecting pipes, a worker can insert the splicing section 1 into the connecting pipe to be assembled, as shown in fig. 3 and 4, in this embodiment, the splicing section 1 includes a connecting section 11 and an insertion section 12, and the insertion section 12 is connected to the limiting section 2 through the connecting section 11. During assembly, the insertion section 12 is inserted into the connecting pipe 8 to be assembled, so that the joint of the two connecting pipes is sealed.

For example, to improve the sealing effect of the sealing sleeve 4, the sealing sleeve 4 may be made of a rubber material in the present embodiment.

In order to improve the sealing effect at the joint of the two connecting pipes, the sealing connecting pipe described in this embodiment applies an axial pressure to the sealing sleeve 4 through the pressing sleeve 5 and the adjusting sleeve 6. Specifically, the extrusion sleeve 5 is sleeved outside the sealing sleeve 4, and the extrusion sleeve 5 can slide along the axial direction of the sealing sleeve 4.

As shown in fig. 2, the pressing sleeve 5 includes a pressing ring 51 and a threaded section, the pressing ring 51 is located on a side of the sealing sleeve 4 away from the limiting section 2, and one end of the threaded section is connected to the pressing ring 51.

When the sealing performance of the two connecting pipes needs to be improved, a worker can rotate the adjusting sleeve 6 towards the limiting section 2. After the adjusting sleeve 6 contacts the limiting section 2, the rotation of the adjusting sleeve 6 is converted into an acting force acting in the axial direction of the extrusion sleeve 5 through threads, and at the moment, the extrusion ring 51 moves towards the limiting section 2. After the extrusion ring 51 is contacted with the sealing sleeve 4, the movement of the extrusion sleeve 5 can cause the pressure in the axial direction to the sealing sleeve 4, the sealing sleeve 4 can be elastically deformed by the pressure, the inner wall of the sealing sleeve 4 can be expanded inwards at the moment, the expanded inner wall can be attached to the outer walls of the connecting pipe 8 to be assembled and the splicing section 11, and the sealing connection of the two connecting pipes can be realized at the moment.

When the two connection pipes need to be disassembled, the worker can rotate the adjusting sleeve 6 reversely, so that the pressure acting on the sealing sleeve 4 can be eliminated, and the sealing sleeve 4 is deformed. After the sealing sleeve 4 is in a complex shape, a worker can pull out the connecting pipe body from the connecting pipe 8 to be assembled, so that the two connecting pipes are separated.

Optionally, in order to prevent the adjusting sleeve 6 from being disengaged from the threaded section during disassembly, the pressing sleeve 5 further comprises a stop ring 53. Specifically, the limiting ring 53 is sleeved outside the conveying section 3, and the limiting ring 53 is connected with one end of the threaded section, which is far away from the extrusion ring 51.

Compared with the existing flange connection structure, the sealing connecting pipe does not need to fasten and level the flange bolts one by one during assembly, so that the assembly and disassembly difficulty of the two connecting pipes can be reduced, and the assembly efficiency of the gas-liquid separator can be improved.

Fig. 5 is a cut-away inside view of the sealing sleeve 4 in the present embodiment, and as shown in the figure, in order to improve the sealing effect at the splicing position of two connecting pipes, the sealing sleeve 4 includes a first sealing section 41 and a second sealing section 42. The inner diameter of the second sealing section 42 is larger than the inner diameter of the first sealing section 41, and a sealing end surface 43 is formed before the inner wall of the first sealing section 41 and the inner wall of the second sealing section 42. After the sealing connecting pipe is inserted into the connecting pipe 8 to be assembled, the end face of the connecting pipe 8 to be assembled is abutted against the sealing end face 43, and the splicing gap of the two connecting pipes can be blocked through the sealing end face 43, so that the sealing effect after the connecting pipes are connected is improved.

In this embodiment, in order to increase the area of the sealing end surface 43, optionally, the outer diameter of the connecting section 11 is smaller than the outer diameter of the inserting section 12, the first sealing section 41 is sleeved on the connecting section 11, and the inner diameter of the first sealing section 41 is equal to the outer diameter of the connecting section 11. The second sealing section 42 is located outside the insertion section 12, and the inner diameter of the second sealing section 42 is larger than the outer diameter of the insertion section 12. Through the setting, the inner wall of the second sealing section 42, the sealing end surface 43 and the outer wall of the insertion section 12 are formed in the sealing groove, after the pipe 8 to be assembled is inserted into the sealing groove, the end part of the pipe 8 to be assembled is sealed by the sealing end surface 43, and the side wall of the pipe 8 to be assembled is fastened by the inner wall of the second sealing section 42 after being extruded, so that the two pipes can obtain a good sealing connection effect.
