Description

Technical Field

[0001] This utility model belongs to the field of pipeline connection technology, and specifically relates to a connection sleeve for preventing pipeline bursting. Background Technology

[0002] Pipelines are mainly used in engineering projects requiring long-distance transportation of water supply, drainage, gas, and industrial fluids. Pipeline fittings are a crucial part of this process. As the name suggests, pipeline fittings are accessories used to connect two sections of pipeline. These fittings play a vital role in ensuring a secure connection and seal between pipelines. Different types of pipelines require different functional fittings for connection.

[0003] For gas transmission pipelines, traditional connecting sleeves have poor sealing performance. When connecting two gas pipeline sections, leakage at the connecting sleeve can cause a loss of transmitted gas. Moreover, due to the unstable connection of traditional connecting sleeves and the unstable gas pressure inside the pipeline, when a sudden increase in pressure occurs, the pressure inside the pipeline cannot be released, which can cause the two connecting pipeline sections to burst, that is, to break off from the connecting sleeve, causing an interruption of transmission. In severe cases, the bursting pipeline can also fly out and hit nearby construction workers, creating a safety hazard for construction operations.

[0004] Therefore, there is an urgent need to design a connection sleeve to prevent pipeline bursting. Utility Model Content

[0005] The purpose of this utility model is to provide a connecting sleeve that prevents pipeline rupture, thereby overcoming the technical problems existing in the background art. By adding a discharge structure to the traditional connecting sleeve to release the air pressure inside the pipe in a timely manner, pipeline rupture is prevented, and the connection stability of the connecting sleeve is further improved. The specific technical solution is as follows:

[0006] A pipe burst prevention connecting sleeve is used to connect two gas pipelines. It includes a connector, a first half sleeve, a second half sleeve, and a sealing element. The first half sleeve and the second half sleeve are fitted onto the connection point of the two gas pipelines and are fixedly connected by the connector. The first half sleeve and the second half sleeve form a connecting sleeve. The sealing element is located between the outer wall of the gas pipeline and the sleeve surface of the connecting sleeve and is pressed against the outer wall of the gas pipeline by the connecting sleeve.

[0007] Both the first half-set and the second half-set are equipped with a discharge structure to allow the gas pressure escaping from the joint of the two gas pipelines to be discharged from the discharge structure.

[0008] Preferably, the discharge structure includes a discharge pipe and a discharge ball, an installation cavity is formed inside the discharge pipe, the installation cavity is connected to the discharge pipe, and the discharge ball can roll inside the installation cavity.

[0009] Preferably, the diameter of the upper and lower openings of the mounting cavity is smaller than the inner diameter of the discharge pipe, and the discharge ball can slide along the length of the mounting cavity.

[0010] Preferably, the surface of the unloading ball is smooth, and the inner wall of the mounting cavity is smooth.

[0011] Preferably, the first half-set and the second half-set have the same structure.

[0012] Preferably, the first half-set includes an arc-shaped sleeve plate and a connecting mounting plate. The connecting mounting plate is provided on both opposite ends of the arc-shaped sleeve plate. The connecting mounting plate is provided with connecting holes. The arc-shaped sleeve plate is provided with a plurality of discharge pipes, and the discharge pipes penetrate the arc-shaped sleeve plate.

[0013] Preferably, the connector includes a connecting bolt and a locking nut. The connecting bolt passes through a connecting hole provided on the first half-sleeve and the second half-sleeve to fix the first half-sleeve and the second half-sleeve together. The locking nut is threadedly connected to the connecting bolt.

[0027] Example

[0028] like Figures 1 to 3 As shown, a pipe burst prevention connecting sleeve is used to connect two gas pipe sections 100 and fix them together to ensure smooth delivery. Specifically, the connecting sleeve includes a connector 200, a first half-sleeve 300, a second half-sleeve 400, and a sealing element 500. The first half-sleeve 300 and the second half-sleeve 400 are fitted onto the connection point of the two gas pipe sections 100 and fixedly connected by the connector 200. The first half-sleeve 300 and the second half-sleeve 400 form a connecting sleeve. The sealing element 500 is located between the outer wall of the gas pipe 100 and the sleeve surface of the connecting sleeve and is pressed against the outer wall of the gas pipe 100 by the connecting sleeve. The sealing element 500 improves the sealing performance of the connection between the two pipes.

[0029] Preferably, both the first half-set 300 and the second half-set 400 are provided with a discharge structure 600, so that the gas pressure escaping from the joint of the two gas pipelines 100 can be discharged from the discharge structure 600. When the conveying pressure in the conveying pipeline is stable, the discharge structure is in an automatically closed state (minor leaks are negligible, and the default state is an ideal state). When the conveying pressure in the conveying pipeline is too high, the gas pressure will be released from the discharge structure 600 to ensure the pipeline pressure is stable and to prevent the two pipes from bursting from the connecting sleeve and causing a safety accident.

[0030] In some preferred embodiments, the discharge structure 600 includes a discharge pipe 610 and a discharge ball 620. The discharge pipe 610 forms an installation cavity for communicating with the outside. The installation cavity is located at the outward end of the discharge pipe 610 and communicates with the discharge pipe 610. The discharge ball 620 can roll within the installation cavity. To ensure that the discharged air pressure can effectively act on the discharge ball 620 and drive it to rotate to achieve the discharge function, a guide slope can also be provided within the installation cavity so that the discharged air pressure acts tangentially on the discharge ball 620 and drives it to roll within the installation cavity. Furthermore, the diameter of the upper and lower openings of the mounting cavity is smaller than the inner diameter of the discharge pipe 610. This design aims to prevent the discharge ball 620 from sliding out of the discharge pipe 610 while remaining within the mounting cavity. The discharge ball 620 can slide along the length of the mounting cavity (more precisely, it fluctuates within the mounting cavity due to air pressure). It is worth noting that to reduce friction between the discharge ball 620 and the mounting cavity, and to ensure that the discharged air pressure can better drive the rolling of the discharge ball 620 to better release pressure, the surface of the discharge ball 620 is smooth, and the inner wall of the mounting cavity is smooth.

[0031] Furthermore, the opening / closing of the discharge pipe 610 can be in the following situations:

[0032] 1. When the two gas pipelines 100 are in normal operation, the unloading ball 620 is pressed against the upper opening of the mounting cavity (i.e., the opening of the unloading pipe 610 facing outward). At this time, the gas pressure in the pipe is insufficient to drive the unloading ball 620 to roll. Therefore, the communication channel between the unloading pipe 610 and the outside is closed.

[0033] 2. When the two gas pipelines 100 are in normal operation, the gas pressure inside the pipeline is insufficient to push the unloading ball 620 to the upper opening of the mounting cavity. At this time, the unloading ball 620 falls under its own weight and blocks the lower opening of the mounting cavity. Therefore, the connection between the unloading pipe 610 and the outside world is closed at this time.

[0034] 3. During the gas delivery process of the two gas pipelines 100, the gas pressure inside the pipeline suddenly increases due to instability. At this time, the unloading ball 620 is pressed against the upper opening of the installation cavity by the pipeline pressure. However, when the pipeline pressure urgently needs to be released, it continues to act on the unloading ball 620, driving the unloading ball 620 to rotate and complete the pressure relief, preventing the two pipelines from bursting at the connection. It is worth mentioning that during the pressure relief process, if the construction personnel see that the unloading ball 620 is obstructed and cannot rotate, they can manually drive the unloading ball 620 to rotate to achieve the unloading operation.

[0035] In some preferred embodiments, the first half-set 300 and the second half-set 400 have the same structure. The first half-set 300 includes an arc-shaped sleeve plate 310 and a connecting mounting plate 320. The connecting mounting plate 320 is provided on both opposite ends of the arc-shaped sleeve plate 310, and the connecting mounting plate 320 is provided with a connecting hole. (Similarly, the second half-set 400 has the same structure.) The arc-shaped sleeve plate 310 is provided with a plurality of discharge pipes 610. The number of discharge pipes 610 is set according to the requirements to improve the discharge effect. The discharge pipes 610 pass through the arc-shaped sleeve plate 310 to ensure that the gas leaking from the junction of the two gas pipelines 100 can be released to the outside through the discharge pipes 610 on the first half-set 300 / second half-set 400. The connector 200 includes a connecting bolt 210 and a locking nut 220. The connecting bolt 210 passes through the connecting holes provided on the first half-sleeve 300 and the second half-sleeve 400 to fix the first half-sleeve 300 and the second half-sleeve 400 together. The locking nut 220 is threadedly connected to the connecting bolt 210.

[0036] In some preferred embodiments, the sealing element 500 includes two U-shaped rubber gaskets. The sealing element 500 is fitted over the outer wall of the gas pipeline 100. Notably, the two U-shaped rubber gaskets in the sealing element 500 are joined side-to-side and cover the outer wall of the joint between the two gas pipeline sections 100. The joined edges of the two U-shaped rubber gaskets correspond to the joint connection between the first half-set 300 and the second half-set 400, ensuring that gas escaping from the joint between the two gas pipeline sections 100 is blocked by the sealing element 500 and cannot leak from the joint between the two halves, thereby improving the connection sealing of the pipeline.

[0037] Specifically, during installation, first, the delivery ports of the two gas pipelines 100 are connected. Then, the two U-shaped rubber gaskets in the sealing element 500 are joined edge-to-edge and wrapped around the outer wall of the connection point between the two gas pipelines 100. Next, the first half-set 300 and the second half-set 400 are installed, covering the positions where the sealing element 500 is installed, ensuring that the connecting holes on the first half-set 300 align with the corresponding connecting holes on the second half-set 400. The connecting bolt 210 is passed through the two connecting holes and then tightened by the locking nut 220. At this time, the sealing element 500 is stably pressed onto the outer wall of the gas pipeline 100 by the connecting sleeve. Similarly, as described above, the connection between the first half-set 300 and the second half-set 400 corresponds to the joint of two U-shaped rubber pads to prevent gas escaping from the connection of the gas pipeline 100 from leaking out from there. The through-hole in the middle of the U-shaped rubber pad facilitates the flow of gas escaping from the joint of the two connected gas pipelines 100 to the discharge pipe 610.

[0038] In summary, this utility model provides a connecting sleeve to prevent pipeline rupture. This connecting sleeve prevents pipeline rupture by adding a discharge structure to the traditional connecting sleeve to release the air pressure inside the pipe in a timely manner, while also further improving the connection stability of the connecting sleeve.
