Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, specifically to an emergency leak-sealing device for high-pressure pipelines. Background Technology

[0002] High-pressure pipelines serve as the core transport carriers in industries such as petroleum, natural gas, and chemicals. Their operating pressures often reach 10-40 MPa, and the media they transport are often corrosive, flammable, and explosive. If leaks occur at critical locations such as pipeline joints and connectors, it will not only lead to resource waste and environmental pollution, but may also cause major safety accidents such as explosions and poisoning.

[0003] When two sets of pipes are sealed together, they are usually connected as a whole by a sealing flange, allowing liquid substances to flow and be transported inside the pipes. However, during long-term use, gaps may appear at the connection between the two sets of pipes due to corrosion, erosion, loose bolts, etc., leading to liquid leakage. If the connection cannot be actively sealed in time, it will affect the normal use of the device to some extent. Utility Model Content

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-pressure pipeline emergency leak sealing device, comprising a pipeline one and a pipeline two connected and installed therewith, and further comprising; The two sets of connecting seats are respectively installed at the connection ends of pipe one and pipe two, and are sealed and installed with pipe one as a whole through the two sets of connecting seats. A fixing component is installed on the outside of the connection between the connecting seat and pipe one and pipe two, and is used to fix the connection between the connecting seat and pipe one and pipe two. An emergency component is installed on the connector. When a leak occurs at the connection between the connector and pipe one and pipe two, the emergency component expands upon contact with water to reduce the gap at the connection between the connector and pipe one and pipe two.

[0014] This utility model has the following beneficial effects: 1. By installing an emergency component on the connector, when the medium in pipe 1 and pipe 2 leaks, the water-swellable rubber material of the first water-stop strip expands rapidly upon contact with water, causing the expanded water-stop strip to fill the leak gap between the connector and the pipe. When the water-stop strip inside the connector expands, the butterfly spring is compressed, generating a reverse elastic force, which keeps the water-stop strip tightly attached to the outer wall of pipe 1 and the inner wall of the connector, preventing the water-stop strip from detaching from the gap due to displacement. At the same time, it prevents the gap between the connector and pipes 1 and 2 from widening further, further enhancing the sealing between the connector and pipes 1 and 2, quickly sealing the leak at the connection, and thus improving the working efficiency of the device to a certain extent.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] The following is based on Figure 1 - Figure 5 This invention describes the high-pressure pipeline emergency leak sealing device provided in the embodiments of the present invention.

[0020] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a high-pressure pipeline emergency leak sealing device, including a pipeline 1 and a pipeline 2 connected and installed therewith, and also includes a connecting seat 3. Two sets of connecting seats 3 are respectively installed at the connection ends of the pipeline 1 and the pipeline 2, and are sealed and installed with the pipeline 1 as a whole through the two sets of connecting seats 3. Fixing component 4 is installed on the outside of the connection between the connecting seat 3 and pipe 1 and pipe 2, and is used to fix the connection between the connecting seat 3 and pipe 1 and pipe 2. Emergency component 5 is installed on the connecting seat 3. When a leak occurs at the connection between the connecting seat 3 and pipe 1 and pipe 2, the emergency component 5 expands when it comes into contact with water to reduce the gap at the connection between the connecting seat 3 and pipe 1 and pipe 2. The emergency component 5 includes multiple sets of water-stop strips 501 installed on the inner wall of the connecting seat 3. Multiple sets of butterfly springs 502 are installed on the outer side of the connecting seat 3. The cross-section of the water-stop strips 501 is trapezoidal and the cross-section of the butterfly springs 502 is trumpet-shaped. The fixing component 4 includes fixing clamps 401 and 402 installed on the outer side of the connection between pipe 2 and connecting seat 3. The fixing clamps 401 and 402 are arc-shaped and respectively set on the outer side of pipe 2 and connecting seat 3. Limiting grooves 6 are equally spaced on the surfaces of pipe 1 and pipe 2. The cross-section of the limiting grooves 6 is trapezoidal and the size and shape of the limiting grooves 6 match those of the water-stop strips 501. In this embodiment, during device use, after the connecting seat 3 is installed with pipe 1 and pipe 2, the trapezoidal limiting grooves 6 on the surfaces of pipe 1 and pipe 2 engage with the trapezoidal waterstop strip 501 on the inner wall of the connecting seat 3. The limiting grooves 6 radially limit the waterstop strip 501, preventing it from shifting due to vibration during normal medium transport. Arc-shaped fixing clamps 401 and 402 are respectively fastened to the outer side of the connection between pipe 2 and the connecting seat 3. The arc-shaped structure ensures a secure fit between the fixing clamps 401 and 402 and the outer wall of pipe 1, pipe 2, and the connecting seat 3. The bolt pre-tightening force rigidly fixes the connecting seat 3 to pipe 1 and pipe 2, preventing axial or radial displacement of the pipes due to medium impact or external vibration, ensuring the stability of the initial sealing system. After long-term use, gaps may appear at the connection between the connecting seat 3 and pipe 1 and pipe 2 due to corrosion, erosion, or loosening of bolts. When a leak occurs in the medium inside pipes 1 and 2, the leaking medium seeps through the gap into the space between the inner wall of the connector 3 and the outer wall of pipe 1, coming into contact with the water-stop strip 501 on the inner wall of the connector 3. The water-stop strip 501 is made of water-swellable rubber, which expands rapidly upon contact with water. The sidewall of the limiting groove 6 restricts the water-stop strip 501 from expanding radially outwards towards pipes 1 and 2, allowing the expanded water-stop strip 501 to directionally fill the leak gap between the connector 3 and the pipes. When the water-stop strip 501 inside the connector 3 expands, the butterfly spring 502 is compressed, generating a reverse elastic force that keeps the water-stop strip 501 tightly pressed against the outer wall of pipe 1 and the inner wall of the connector 3. This prevents the water-stop strip 501 from detaching from the gap due to displacement, and also prevents the gap between the connector 3 and pipes 1 and 2 from widening further, thus further enhancing the sealing between the connector 3 and pipes 1 and 2. Simultaneously, the leaking medium enters the placement cavity 8 inside the fixed seat 7 and comes into contact with the second water-stop strip 801 inside the placement cavity 8. The second water-stop strip 801 expands rapidly, filling the gap between the placement cavity 8 and the outer wall of the connecting seat 3. At the same time, the expanded second water-stop strip 801 generates radial pressure on the connecting seat 3, causing the connecting seat 3 to tighten towards the pipeline, indirectly enhancing the fit between the first water-stop strip 501 and the pipeline. At this time, a double-layer sealing system of the first water-stop strip 501 and the second water-stop strip 801 is formed, blocking the leakage medium from spreading to the outside of the device. At the same time, if there is still slight leakage after the double-layer sealing, the pre-tightening force can be adjusted by rotating the threaded sleeve 701 inside the fixed seat 7, so that the sealing strip 301 of the connecting seat 3 fits more tightly with the sealing groove 11, further strengthening the initial seal and achieving coordinated leakage plugging through active adjustment and passive expansion. The pressure relief groove 9 opened on the fixed seat 7 can release part of the pressure in time through the one-way valve 10 when the internal pressure of the device is too high, avoiding damage to the device due to excessive pressure, thereby increasing the safety of the device during use.

[0021] Specifically, a sealing strip 301 is fixedly installed on one side of the connecting seat 3, and a sealing groove 11 is opened on the inner side of the other connecting seat 3 corresponding to the sealing strip 301. A fixing seat 7 is fitted on the outer side of the two sets of connecting seats 3. A threaded sleeve 701 is installed inside the fixing seat 7 through a threaded structure. A placement cavity 8 is opened on the inner side of the fixing seat 7. A water-stop strip 801 is installed on the inner side of the placement cavity 8. A pressure relief groove 9 is opened on the fixing seat 7. A one-way valve 10 is installed inside the pressure relief groove 9. In this embodiment, two sets of connecting seats 3 are respectively fitted onto the connecting ends of pipe 1 and pipe 2, so that the connecting end of pipe 1 is inserted into one set of connecting seats 3 and the connecting end of pipe 2 is inserted into the other set of connecting seats 3. The sealing strip 301 on one side of one set of connecting seats 3 is precisely aligned with the sealing groove 11 on the inner side of the other set of connecting seats 3. After being squeezed, the sealing strip 301 fills the gap of the sealing groove 11, forming an initial axial seal, blocking the medium in the pipe from leaking from the joint of the two sets of connecting seats 3. Then, the fixing seat 7 is fitted onto the outside of the two sets of connecting seats 3. The threaded sleeve 701 inside the fixing seat 7 is screwed into the thread on the outer wall of the connecting seat 3, so that the placement cavity 8 inside the fixing seat 7 completely covers the joint of the two sets of connecting seats 3. The water-stop strip 801 inside the placement cavity 8 is in a natural state. Through the double seal of the sealing strip 301 and the fixing seat 7, the risk of leakage is further reduced. At the same time, the self-locking nature of the threaded sleeve 701 can prevent the fixing seat 7 from loosening under high pressure conditions. The working principle and usage process of this utility model are as follows: Two sets of connecting seats 3 are respectively fitted onto the connecting ends of pipe 1 and pipe 2. The sealing strip 301 of one set of connecting seats 3 is pressed and fitted with the sealing groove 11 of the other set to form an initial axial seal, preventing the medium from leaking from the joint of the connecting seats 3. The fixing seat 7 is fitted onto the outside of the connecting seat 3, and the threaded sleeve 701 is screwed into the fixing seat 7, so that the placement cavity 8 covers the joint of the connecting seat 3. Then, the fixing clamps 401 and 402 respectively fasten the connection between pipe 1 and pipe 2 and the connecting seat 3. Bolts secure fixing clamp 401 and fixing clamp 402. When gaps appear between connecting seat 3 and pipe 1 and pipe 2 due to corrosion or loosening, and the medium leaks, the trapezoidal limiting groove 6 on the surface of the water-stop strip 501, which expands when exposed to water, restricts its radial expansion outward, allowing the water-stop strip 501 to directionally fill the leak gap. At the same time, the flared butterfly spring 502 on the outside of connecting seat 3 is squeezed by the expansion tension, generating reverse elasticity, pushing the water-stop strip 501 to continuously adhere tightly to the inner wall of pipe 1 and connecting seat 3, preventing displacement that could cause the seal to detach, and preventing the gap from widening.
