[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0034] Example: Figures 1-8 As shown, this embodiment provides a rapid leak-sealing device for emergency repair of leaks in high-temperature and high-pressure heating pipelines, including an injection mold 1, a balance plate 2, a lead screw 3, a connecting plate 4, and a connecting strap 5. The injection mold 1 is used to fit and abut against the side wall of the pipeline 6. An injection groove 11 is opened on the side of the injection mold 1 opposite to the pipeline 6. The injection groove 11 and the side wall of the pipeline 6 form an injection cavity, in which sealant is injected to seal the leak in the pipeline 6. At least one injection port 12 is opened on the injection mold 1 for connecting an injection device. The balance plate 2 is evenly distributed circumferentially. A number of first mounting screw holes are provided, and an adjusting rod 21 is threaded into the first mounting screw holes. The lower end of the adjusting rod 21 is used to abut against the injection mold 1. A limiting groove 22 is provided at the upper center of the balance plate 2. A second mounting screw hole 43 is opened in the middle of the connecting plate 4. A lead screw 3 is threaded into the second mounting screw hole 43. One end of the lead screw 3 is rotatably limited in the limiting groove 22 of the balance plate 2. A rotating handle 31 is provided at the other end of the lead screw 3. A connecting strap 5 is used to wrap around the leaking pipe 6. The two ends of the connecting strap 5 are respectively fixedly connected to the two ends of the connecting plate 4.

[0035] With the above setup, rotating the handle 31 drives the lead screw 3 to rotate, causing the connecting plate 4 on the lead screw 3 to move along the axis of the lead screw 3, thereby tightening or loosening the steel belt and adjusting the clamping force between the injection mold 1 and the pipe 6. The injection ports 12, serving as channels for sealant injection, are rationally designed in terms of their number and distribution based on the pipe diameter and leakage situation of the leaking pipe 6, ensuring that the sealant can be evenly filled into the leaking area of ​​the pipe 6. The balance plate 2 and the adjusting rod 21 work together to abut against the injection mold 1, ensuring that the injection mold 1 always maintains optimal contact with the surface of the leaking pipe 6, thus guaranteeing that the sealant is injected evenly and stably into the leak point, avoiding sealing problems caused by the offset or tilting of the injection mold 1. This achieves rapid positioning and efficient sealing of the leaking pipe 6 under pressure and without interrupting heating, reducing heating interruption time, lowering repair costs, and improving the reliability and stability of the heating system.

[0036] In this embodiment, a quick leak-stopping device for emergency repair of leaks in high-temperature and high-pressure heating pipelines is provided. A water outlet hole is opened on the glue injection mold 1, a water outlet pipe 14 is installed at the water outlet hole, and a valve 15 is provided on the water outlet pipe 14.

[0037] In this embodiment, a quick leak-stopping device for emergency repair of leaks in high-temperature and high-pressure heating pipelines uses an adjusting rod 21 as an adjusting bolt.

[0038] In this embodiment, a quick-closing device for emergency repair of leaks in high-temperature and high-pressure heating pipelines has four adjusting rods 21.

[0039] In this embodiment, a quick leak-stopping device for emergency repair of leaks in high-temperature and high-pressure heating pipelines has a balance plate 2 located at the center of the glue injection mold 1.

[0040] In this embodiment, a quick-closing device for emergency repair of leaks in high-temperature and high-pressure heating pipelines uses a steel strip as the connecting band 5. The steel strip possesses high strength and good flexibility, allowing it to tightly wrap around the outer wall of the leaking pipeline 6, providing reliable clamping force to the injection mold 1 and creating a relatively sealed space between it and the pipeline 6.

[0041] In this embodiment, a quick-closing device for emergency repair of leaks in high-temperature and high-pressure heating pipelines includes mounting holes 41 at opposite ends of a connecting plate 4 for a steel strip to pass through. Several locking rods 42, threaded onto the sidewalls of the mounting holes 41, are threaded onto the connecting plate 4. The locking rods 42 are used to press against the connecting strip 5 within the mounting holes 41. The locking rods 42 are used to initially fix the connecting strip 5 and other components onto the leaking pipeline 6, ensuring the positional stability of the leak-closing device during installation.

[0042] In this embodiment, a quick-locking device for emergency repair of leaks in high-temperature and high-pressure heating pipelines uses a screw as the locking rod 42.

[0043] In this embodiment, a rapid leak-sealing device for emergency repair of leaks in high-temperature and high-pressure heating pipelines includes an injection mold 1 comprising an arc-shaped plate 16. A retaining strip 17 is fixedly installed around the arc-shaped plate 16 on the side opposite to the side wall of the pipeline 6. The arc-shaped plate 16 and the retaining strips 17 form the injection groove 11. The arc-shaped plate 16 is designed with a corresponding arc-shaped structure according to different pipe diameters of the pipeline 6, enabling it to fit tightly against the surface of the leaking pipeline 6, forming a sealed chamber and guiding the sealant to accurately fill the leak point and surrounding gaps.

[0044] In this embodiment, a quick leak-stopping device for emergency repair of leaks in high-temperature and high-pressure heating pipelines is provided with a glue injection pipe 18 fixedly installed at the glue injection port 12. The glue injection pipe 18 is used to connect to the glue injection equipment.

[0045] In this embodiment, a quick leak-stopping device for emergency repair of leaks in high-temperature and high-pressure heating pipelines features an ergonomically designed rotating handle 31 that facilitates the application of force by the operator. The rotating handle 31 enables the driving operation of other components of the leak-stopping device.

[0046] The operation steps are as follows:

[0047] 1. Installation and Positioning: First, wrap the steel strip around the designated position of the leaking pipe 6 and initially fix it to the connecting plate 4 with screws. Then, install the glue injection mold 1 and the balance plate 2, and adjust the position and angle of the glue injection mold 1 to make it accurately fit the surface of the pipe 6 near the leak point.

[0048] 2. Sealing: The operator rotates the rotary handle 31, which drives the lead screw 3 to rotate. During the rotation of the lead screw 3, the connecting plate 4 moves upward, thereby gradually tightening the steel strip. As the steel strip tightens, the glue injection mold 1 fits tightly against the outer wall of the leaking pipe 6, forming a relatively sealed space, creating conditions for subsequent glue injection operations.

[0049] 3. Sealing with sealant: Special sealant is loaded into the sealant injection equipment and injected through the injection hole into the sealing cavity formed between the injection mold 1 and the surface of the pipe 6. The sealant cures rapidly under high temperature and pressure, forming a reliable sealing structure, thereby effectively sealing the leaking pipe 6.
