Description

Technical Field

[0001] This utility model relates to the field of gas pipeline technology, and in particular to a sealing device for emergency repair of gas pipelines. Background Technology

[0002] In gas transmission systems, gas pipelines are prone to leaks due to corrosion after long-term use, external construction damage, material aging, or pressure fluctuations. Gas leaks not only waste energy but can also cause serious safety accidents such as explosions and poisoning, posing a great threat to the lives and property of surrounding residents and the environment. Therefore, quickly and effectively sealing the leak point is the core part of gas pipeline emergency repair.

[0003] Currently, some existing gas pipeline leak sealing devices use a single clamping method, which can achieve initial sealing, but the clamp is not tightly fitted to the pipeline surface, especially when there are slight unevennesses on the pipeline surface, which can easily form gaps between the two, leading to continuous gas leakage and poor sealing effect. Other devices are complicated to operate, requiring professional personnel to use multiple tools to complete the work. In emergency repair scenarios, the operation time is often too long, which delays the best repair time and increases safety risks. Therefore, we have introduced a new sealing device for gas pipeline emergency repair construction. Utility Model Content

[0004] The main purpose of this utility model is to provide a sealing device for emergency repair of gas pipelines, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A sealing device for emergency repair of gas pipelines includes a first hoop and a second hoop. A fixing block is fixedly connected to the inner surface of both the first and second hoops. A sealing clamp is fixedly connected to the end of each fixing block away from the first and second hoops. A rubber air cushion is fixedly connected to the end of each sealing clamp away from the fixing block. A connecting pipe is fixedly connected to the front end of each rubber air cushion. A connecting cylinder is fixedly connected to the end of each connecting pipe away from the rubber air cushion. A valve is provided on the outer surface of each connecting cylinder. An air inlet pipe is fixedly connected to the end of each connecting cylinder away from the connecting pipe. Connecting ears are fixedly connected to the left and right sides of the outer surface of the first hoop and the left and right sides of the outer surface of the second hoop. A bolt is inserted and connected between adjacent connecting ears.

[0007] Preferably, both the first hoop and the second hoop are semi-circular structures, and the first hoop and the second hoop are the same size.

[0008] Preferably, the first hoop and the second hoop are connected by two bolts.

[0009] By adopting the above technical solution, the first and second clamping rings are connected by two bolts, which can ensure the stability of the connection and ensure that the clamping rings are not easy to loosen under the pressure of gas in the pipeline, so that the sealing clamp can stably clamp the leakage point.

[0010] Preferably, both of the sealing plates are arc-shaped structures.

[0011] By adopting the above technical solution, both sealing clamps are arc-shaped, which can better fit the outer circumference of the gas pipeline, increase the contact area between the sealing clamp and the pipeline, and make the clamping force distribution more uniform.

[0012] Preferably, the two rubber air cushions are symmetrically distributed vertically, and both rubber air cushions are hollow structures.

[0013] By adopting the above technical solution, the two rubber air cushions are symmetrically distributed vertically, which can simultaneously form a wrap-around seal on the leak point and surrounding area from both the top and bottom sides of the pipe when the sealing clamp is tightened, so that the expanded air cushions are subjected to more balanced force.

[0014] Preferably, the two air intake pipes are respectively connected to the interior of the two rubber air cushions through two connecting pipes.

[0015] By adopting the above technical solution, an external air pump can be connected through the air inlet pipe to inflate the rubber air cushion.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The sealing clamp is clamped to the leak point by the bolt connection between the first and second clamps, which can quickly form a preliminary seal, reduce the large amount of gas leakage in the early stage of emergency repair, and buy time for subsequent operations. The bolt connection is stable and reliable, ensuring that the sealing clamp is not easy to loosen under the pressure of gas in the pipeline, thus ensuring the effectiveness of the preliminary seal.

[0018] 2. The rubber air cushion is inflated by an external air pump, allowing it to tightly fill the gap between the gas pipeline and the sealing clamp using the elastic properties of rubber. This further enhances the sealing performance. Even if there are some unevenness on the pipeline surface or a small gap between the sealing clamp and the pipeline, the inflated rubber air cushion can still fit fully, preventing gas from leaking out of the gap and further improving the sealing effect. The entire device is easy to operate, and the sealing can be completed by bolt connection and inflation of the rubber air cushion. No complicated professional skills are required, making it easy for emergency repair personnel to get started quickly, improving repair efficiency, and adapting to emergency scenarios where every second counts in gas leak repair.

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] A sealing device for emergency repair of gas pipelines includes a first hoop 1 and a second hoop 2. Fixing blocks 3 are fixedly connected to the inner surfaces of both the first hoop 1 and the second hoop 2. Sealing clamps 4 are fixedly connected to the ends of the two fixing blocks 3 away from the first hoop 1 and the second hoop 2. Rubber air cushions 5 are fixedly connected to the ends of the two sealing clamps 4 away from the fixing blocks 3. Connecting pipes 6 are fixedly connected to the front ends of the two rubber air cushions 5. Connecting cylinders 7 are fixedly connected to the ends of the two connecting pipes 6 away from the rubber air cushions 5. Valves 8 are provided on the outer surfaces of the two connecting cylinders 7. Air inlet pipes 9 are fixedly connected to the ends of the two connecting cylinders 7 away from the connecting pipes 6. Connecting ears 10 are fixedly connected to the left and right outer surfaces of the first hoop 1 and the second hoop 2. Bolts 11 are interlocked between adjacent connecting ears 10.

[0030] The above solution achieves the clamping of the sealing plate 4 to the leak point by connecting the first hoop 1 and the second hoop 2 with bolts 11, which can quickly form a preliminary seal, reduce the large amount of gas leakage in the early stage of emergency repair, and buy time for subsequent operations. Moreover, the bolt connection method is stable and reliable, ensuring that the sealing plate 4 is not easy to loosen under the pressure of gas in the pipeline, thus ensuring the effectiveness of the preliminary seal.

[0032] The above solution involves inflating the rubber air cushion 5 using an external air pump. This allows the rubber's elastic properties to tightly fill the gap between the gas pipeline and the sealing clamp 4, further enhancing the sealing performance. Even if there are some unevenness on the pipeline surface or a small gap between the sealing clamp 4 and the pipeline, the inflated rubber air cushion 5 can still fit snugly, preventing gas leakage from the gaps and further improving the sealing effect. The entire device is easy to operate; sealing can be completed by connecting with bolts 11 and inflating the rubber air cushion 5. No complex professional skills are required, making it easy for emergency repair personnel to quickly get started, improving repair efficiency, and adapting to emergency scenarios where every second counts in gas leak repair work.

[0033] It should be noted that this utility model is a sealing device for emergency repair of gas pipelines. During use, the first clamping ring 1 and the second clamping ring 2 are connected by bolts 11, allowing the sealing clamping plate 4 to clamp the leak point, quickly achieving initial sealing and reducing large-scale gas leakage in the initial stage of repair, thus saving time for subsequent operations. Furthermore, the bolt connection 11 is firm and reliable, ensuring that the sealing clamping plate 4 is not easily loosened under the pressure of the gas inside the pipeline, ensuring effective initial sealing. Afterwards, the air inlet pipe 9 is connected to an external air pump, which inflates the rubber air cushion 5, utilizing the rubber's... Its elastic properties allow it to tightly fill the gap between the gas pipeline and the sealing clamp 4, further enhancing the sealing performance. Even if there are some unevenness on the pipeline surface or a small gap between the sealing clamp 4 and the pipeline, the expanded rubber air cushion 5 can still fit fully, preventing gas from leaking from the gap and further improving the sealing effect. In addition, the entire device is easy to operate. Sealing can be completed simply by connecting with bolts 11 and inflating the rubber air cushion 5. No complicated professional skills are required, making it easy for emergency repair personnel to master quickly and improve repair efficiency. It can be well adapted to the time-sensitive emergency scenarios of gas leak repair.
