[0001] The utility model belongs to the technical field of liquid pipeline sealing, and particularly relates to a pipeline connection seal. Background Technique
[0002] During long-distance transportation, multiple pipelines are connected in sequence, and adjacent pipelines are connected and sealed through a connector.
[0003] For existing pipeline connection seals, a connection part is clamped and installed at the joints of the end faces, inner and outer side walls of adjacent pipelines to block the splicing gap of the pipelines, reducing the inner diameter of the pipeline joints, increasing the pressure and flow rate at the joints, impacting the joints and causing leakage at the joints, affecting the sealing effect of pipeline connection. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is to enlarge the diameter of the joints between adjacent pipelines, perform a slow-flow treatment on the liquid transported inside the pipelines, reduce the pressure at the pipeline joints, and improve the sealing effect.
[0005] To solve the above technical problem, the technical solution adopted by the utility model is as follows: A pipeline connection seal includes a communication main body. The communication main body is arranged in a tubular shape. It further includes a connecting pipe, a locking ring, a limit sealing assembly, and a slow-flow mechanism. The connecting pipes are fixedly connected to both ends of the communication main body. The connecting pipes are symmetrically distributed with the communication main body as the center. The locking ring is threadedly connected to the outer side wall of the connecting pipe. The limit sealing assembly is arranged on the inner side wall of the communication main body and is located at the joint of the communication main body and the connecting pipe. The slow-flow mechanism is arranged inside the communication main body and is located between the symmetric limit sealing assemblies;
[0006] Adjusting grooves are formed on the outer side wall of the connecting pipe. The adjusting grooves are arranged in a uniformly spaced annular manner. The outer side wall of the connecting pipe is arranged in an inclined surface.
[0007] Further, the limit sealing assembly includes a limit plate, an insertion pipe, and a sealing rubber ring. The limit plate is fixedly connected to the inner side wall of the communication main body and is located at the joint of the connecting pipe and the communication main body. The limit plate is arranged in an annular shape. The insertion pipe is fixedly connected to the end face of the limit plate close to the connecting pipe. The sealing rubber ring is fixedly connected to the outer side wall of the insertion pipe and is arranged at uniformly spaced intervals along the axial direction of the insertion pipe.
[0008] Further, a limit groove is formed between the outer side wall of the insertion pipe and the inner side wall of the connecting pipe. A sealing gasket is arranged at the corner adjacent to the end face of the inner wall of the connecting pipe and the limit plate.
[0009] Further, the flow-slowing mechanism includes a support rod, a sliding rod, a propeller and a backing plate.

One end of the sliding rod penetrates through the support rod and is slidably arranged inside the support rod. The propeller is rotatably connected to both ends of the sliding rod. The propellers are symmetrically distributed. The backing plate is fixedly connected to the outer side wall of the sliding rod near one end in the water inlet direction of the communication body. A support spring is wound around the outer side wall of the sliding rod, and the support spring is located between the backing plate and the support rod.
[0010] Further, the diameter of the propeller is smaller than the inner diameter of the insertion tube.
[0011] Further, a limiting ring is fixedly connected to the outer side wall of the communication body, and a strip-shaped hole is provided in the end face of the limiting ring.

Rotate and tighten the locking pipe to squeeze the outer wall of the connecting pipe. Through the adjustment groove, the outer wall of the connecting pipe is deformed and contacts the outer wall of the pipeline to lock the pipeline port. Adjacent pipelines pass through the communication body to transfer the liquid flow. The diameter of the communication body is larger than the pipeline connection, increasing the cross-sectional area of the pipeline connection, slowing down the liquid flow rate and pressure. At the same time, the inside of the communication body further slows down the flow rate of the flowing liquid through the flow-slowing mechanism, reducing the pressure at the connection.

[0019] As Figures 1-3 shown, a pipeline connection seal includes a connecting main body 1. The connecting main body 1 is arranged in a tubular shape. It also includes a connecting pipe 2, a locking ring 3, a limit sealing assembly 4 and a flow buffering mechanism 5. The connecting pipe 2 is fixedly connected to both ends of the connecting main body 1. The connecting pipes 2 are symmetrically distributed with the connecting main body 1 as the center. The locking ring 3 is threadedly connected to the outer side wall of the connecting pipe 2. The limit sealing assembly 4 is arranged on the inner side wall of the connecting main body 1 and is located at the connection between the connecting main body 1 and the connecting pipe 2. The flow buffering mechanism 5 is arranged inside the connecting main body 1 and is located between the symmetric limit sealing assemblies 4. An adjusting groove 6 is formed on the outer side wall of the connecting pipe 2. The adjusting grooves 6 are arranged in a ring shape at equal intervals. The outer side wall of the connecting pipe 2 is arranged in an inclined plane. The end faces of adjacent pipelines are inserted into the connecting pipe 2, and the limit sealing assembly 4 is used to clamp and limit the port thereof. The locking ring 3 is rotated to make the locking ring 3 rotate along the inclined outer wall of the connecting pipe 2, squeezing the adjusting groove 6 to deform the connecting pipe 2, locking the pipeline port, and reducing the flow rate and pipeline pressure at the connection through the connecting main body 1 and the internal flow buffering mechanism 5.
[0020] As Figures 2-4 shown, in order to achieve sealing and limiting of the pipeline port, the limit sealing assembly 4 includes a limit plate 7, an insertion pipe 8 and a sealing rubber ring 9. The limit plate 7 is fixedly connected to the inner side wall of the connecting main body 1 and is located at the connection between the connecting pipe 2 and the connecting main body 1. The limit plate 7 is arranged in a ring shape. The insertion pipe 8 is fixedly connected to the end face of the limit plate 7 close to the connecting pipe 2. The sealing rubber ring 9 is fixedly connected to the outer side wall of the insertion pipe 8 and is arranged at equal intervals along the axial direction of the insertion pipe 8. A limit groove 10 is formed between the outer side wall of the insertion pipe 8 and the inner side wall of the connecting pipe 2. A sealing gasket 11 is arranged at the corner adjacent to the end face of the inner wall of the connecting pipe 2 and the limit plate 7. The pipeline port is inserted into the limit groove 10. The inner wall of the pipeline is sleeved on the outer wall of the insertion pipe 8 through multiple sealing rubber rings 9 to seal the pipeline. The outer wall of the pipeline is attached to the inner wall of the connecting pipe 2 and contacts the sealing gasket 11, so that the corner between the pipeline end face and the outer side wall squeezes the sealing gasket 11 to further seal the pipeline and limit the pipeline in the connecting pipe 2.
[0021] As Figure 2 and Figure 3As shown in the figure, in order to reduce the pressure between adjacent pipes and lower the liquid flow rate inside the connecting main body 1, for the pressure regulation at the connection of adjacent pipes, the flow-slowing mechanism 5 includes a support rod 12, a sliding rod 13, a propeller 14, and a backing plate 15. The support rod 12 is fixedly connected to the middle of the inner side wall of the connecting main body 1. One end of the sliding rod 13 penetrates through the support rod 12 and is slidably arranged inside the support rod 12. The propeller 14 is rotatably connected to both ends of the sliding rod 13, and the propellers 14 are symmetrically distributed. The backing plate 15 is fixedly connected to the outer side wall of the sliding rod 13 near one end in the water inlet direction of the connecting main body 1. A support spring 16 is wound around the outer side wall of the sliding rod 13, and the support spring 16 is located between the backing plate 15 and the support rod 12. The sliding rod 13 slides at the middle position of the support rod 12. By the support spring 16 pushing the backing plate 15, one of the propellers 14 is close to the water inlet end of the connecting main body 1. When water enters the connecting main body 1 through the pipe, it pushes the propeller 14 to rotate, slowing down the flow rate. At the same time, the support spring 16 is compressed and contracted, and the sliding rod 13 moves, making the other propeller 14 close to the water outlet end of the connecting main body 1 and rotate at the pipe orifice, slowing down the flow rate into the next section of the pipe, thus realizing the pressure regulation at the connection of adjacent pipes.
[0022] Among them, the diameter of the propeller 14 is smaller than the inner diameter of the insertion pipe 8 to avoid excessive resistance caused by the propeller 14 getting stuck at the pipe port. A limiting ring 17 is fixedly connected to the outer side wall of the connecting main body 1. A strip-shaped hole 18 is provided in the end face of the limiting ring 17 for hoisting the connector and fixedly installing the connector.
[0023] During specific use, the operator inserts the end faces of adjacent pipes into the connecting pipe 2, making the pipe ports insert into the limiting grooves 10. The inner wall of the pipe is sleeved on the outer wall of the insertion pipe 8 through multiple sealing rubber rings 9 to seal the inside of the pipe. The outer wall of the pipe is in contact with the inner wall of the connecting pipe 2 and contacts the sealing gasket 11, so that the corners at the end face and the outer side wall of the pipe squeeze the sealing gasket 11 to seal the pipe end face. Rotate the locking ring 3, making the locking ring 3 rotate along the inclined outer wall of the connecting pipe 2, squeezing the adjusting groove 6 to deform the connecting pipe 2 and lock the pipe port, limiting the pipe inside the connecting pipe 2.
[0024] When the pipes are connected and water enters through the connecting main body, it pushes the propeller 14 near the water inlet end of the connecting main body to rotate, slowing down the flow rate of the liquid entering the connecting main body 1. The diameter of the connecting main body 1 is larger than that of the pipe, and the flow rate inside the connecting main body 1 decreases. At the same time, the support spring 16 is compressed and contracted, and the sliding rod 13 moves, making the other propeller 14 close to the water outlet end of the connecting main body 1 and rotate at the pipe orifice, slowing down the flow rate into the next section of the pipe, realizing the pressure regulation at the connection of adjacent pipes and reducing the leakage at the pipe connection caused by pressure.

The scope of the present utility model is defined by the appended claims and their equivalents.
