Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The inner wall of the sealing sleeve 205 is fixedly connected with a sealing strip 206. The sealing sleeve 205 is connected to a lower pipeline 4 through a fixed piece 207 and a first bolt 208. A plurality of groups of equally spaced limiting grooves 203 are opened on the right side surface of the lower pipeline 4. The right side surface of the first sealing ring 201 is in contact with the left side surface of the lower pipeline 4. The left side surface of the second sealing ring 202 is in contact with the right side surface of the upper pipeline 1. The limiting block 204 and the limiting groove 203 are adapted to each other. The inner wall of the sealing sleeve 205 abuts against the outer wall of the upper pipeline 1. The inner wall of the sealing sleeve 205 abuts against the outer wall of the lower pipeline 4. A threaded hole is opened in the interior of the fixed piece 207. The outer wall of the first bolt 208 is threadedly connected with the inner wall of the threaded hole. The lower surface of the fixed piece 207 is in contact with the surface of the upper pipeline 1. The lower surface of the fixed piece 207 is in contact with the surface of the lower pipeline 4. The side surface of the sealing sleeve 205 is fixedly connected with one end of the fixed piece 207.

[0022] The surfaces of the first sealing ring 201 and the second sealing ring 202 are both provided with grooves having the same size as the limiting groove 203, and the limiting block 204 passes through the first sealing ring 201 and the second sealing ring 202 through these grooves and is connected to the limiting groove 203. At this time, there will be a gap at the connection between the upper pipeline 1 and the lower pipeline 4, and the sealing strip 206 fits with this gap.

[0023] Specifically, through the leakage prevention assembly 2 provided, the staff can make the upper pipeline 1 and the lower pipeline 4 fit with each other through the first sealing ring 201 and the second sealing ring 202, and then seal the upper pipeline 1 and the lower pipeline 4 through the sealing sleeve 205. In this way, through the coordinated cooperation of the first sealing ring 201, the second sealing ring 202 and the sealing sleeve 205, multiple sealing lines can be formed, greatly reducing the probability of leakage and greatly improving the sealing reliability of the pipeline connection.

[0024] Embodiment 2:

[0025] Please refer to the attached Figure 1 、attached Figure 2 and attached Figure 4 On the basis of Embodiment 1, it is further obtained that a fixing assembly 3 is provided at the upper end of the sealing sleeve 205. The fixing assembly 3 includes a first semi-circle 301 and a second semi-circle 304.

[0026] The rotational connection relationship between the fixing block 302 and the fixing rod 303 can enable the staff to adjust the position between the fixing block 302 and the fixing rod 303 more flexibly when installing and disassembling the pipeline connection mechanism, which can facilitate the operation of the staff and improve the installation or disassembly efficiency.

[0027] Specifically, through the fixing assembly 3 provided, during the operation of the pipeline, the staff can place the first semi-circle 301 and the second semi-circle 304 on the sealing sleeve 205, and strengthen the fixation of the leakage prevention assembly 2 through the second bolt 307 and the nut 308. In this way, the leakage prevention assembly 2 can achieve a further stable effect, further enhancing the stability of the sealing sleeve 205 and the entire leakage prevention assembly 2, and reducing the occurrence of sealing loosening caused by factors such as pipeline vibration and pressure fluctuation, thereby more effectively preventing the occurrence of leakage phenomena.

[0028] Working principle of the present utility model: The present utility model is a leakage-proof two-phase flow pipeline connection mechanism for steam and water. First, the staff places the first sealing ring 201 and the second sealing ring 202 in the middle of the upper pipeline 1 and the lower pipeline 4, and then fixes them through the limit block 204 and the limit groove 203. Then, the sealing sleeve 205 is sleeved on the upper surfaces of the upper pipeline 1 and the lower pipeline 4, and the sealing sleeve 205 is fixedly installed on the surfaces of the upper pipeline 1 and the lower pipeline 4 through the first bolt 208 and the fixing piece 207. Secondly, the staff can sleeve the first semi-circle 301 and the second semi-circle 304 on the sealing sleeve 205, and then, through the connection relationship between the fixing block 302 and the fixing rod 303, move the first semi-circle 301 and the second semi-circle 304 closer to each other. Finally, it is fixed on the sealing sleeve 205 through the second bolt 307 and the nut 308.
