Description

Technical Field

[0001] This utility model relates to the field of sulfuric acid pipeline leak prevention technology, specifically a leak-proof pipeline connection component. Background Technology

[0002] The piping system of the dry absorption section in the sulfuric acid workshop is a key component in sulfuric acid production. It is mainly used to transport and process SO3-containing gases and concentrated sulfuric acid media. When protecting the pipeline of the dry absorption section in the sulfuric acid workshop from leakage, a leak-proof pipeline connection component is required.

[0003] Currently, when pipeline leaks occur, if the leak is not serious, the pipeline is usually repaired by waiting for a shutdown opportunity. However, if the leak is more serious, the pipeline needs to be shut down for repair, which means that the pipeline cannot be used normally during the repair process, affecting the efficiency and effectiveness of sulfuric acid transportation and reducing the overall production efficiency of the workshop.

[0004] Based on this, a leak-proof pipe connection assembly is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] In one embodiment, such as Figures 1-4 As shown, a leak-proof pipe connection assembly includes an upper pipe clamp 1 and a lower pipe clamp 2, which are hinged together by a hinge 3.

[0030] The sealing assembly is located at the bottom of the lower pipe clamp 2 and is used to protect the pipeline from leakage.

[0031] Positioning components are respectively installed on the surfaces of the upper pipe clamp 1 and the lower pipe clamp 2, and are used to position and mate the upper pipe clamp 1 and the lower pipe clamp 2.

[0032] A fixing component is disposed on the surface of the positioning component and is used to fix the upper clamp 1 and the lower clamp 2 together.

[0033] In this embodiment, when it is necessary to perform leak prevention protection on a leaking pipeline, simply place the lower pipe clamp 2 and the upper pipe clamp 1 at the location of the leak, and then close the upper pipe clamp 1 and the lower pipe clamp 2 using the hinge 3. After the upper pipe clamp 1 and the lower pipe clamp 2 are closed, fix the upper pipe clamp 1 and the lower pipe clamp 2 using the fixing component. At this point, the entire device can be fixedly installed at the location of the leak in the pipeline. The upper pipe clamp 1, the lower pipe clamp 2, and the sealing component work together to perform leak prevention protection on the pipeline, thereby effectively preventing pipeline shutdown accidents caused by minor leaks. This significantly improves the overall practicality of the device. The positioning component effectively provides positioning, making it easier for workers to position and connect the upper pipe clamp 1 and the lower pipe clamp 2, further enhancing the overall practicality and ease of use of the device.

[0034] In one embodiment, such as Figures 1-3 As shown, the sealing assembly includes a pressure relief pipe 8 connected to the bottom of the lower pipe clamp 2. A pressure relief valve 9 is fixedly installed at the bottom of the pressure relief pipe 8. When it is necessary to perform anti-leakage protection treatment on the pipeline, simply fix the upper pipe clamp 1 and the lower pipe clamp 2 at the leaking part of the pipeline using the fixing assembly. After the upper pipe clamp 1 and the lower pipe clamp 2 are installed, the pressure relief valve 9 is closed. At this time, the sealing treatment can be completed, thereby avoiding pipeline shutdown accidents caused by minor leaks.

[0035] In one embodiment, such as Figures 1-3 As shown, the positioning assembly includes an outer plate 5 fixedly installed on the surface of the upper pipe clamp 1. An insert plate 6 is fixedly connected to the bottom of the outer plate 5, and a positioning frame 7 is fixedly connected to the surface of the lower pipe clamp 2. The upper surface of the positioning frame 7 has a movable groove for the insert plate 6 to move. When the upper pipe clamp 1 and the lower pipe clamp 2 are closed, the insert plate 6 will also be inserted into the positioning frame 7 at the same time. At this time, both the insert plate 6 and the positioning frame 7 can effectively play a positioning role, which makes it easier for the staff to perform positioning and docking between the upper pipe clamp 1 and the lower pipe clamp 2.

[0036] In one embodiment, such as Figure 3 and Figure 4 As shown, the fixing assembly includes connecting blocks 10 symmetrically installed at the bottom of the positioning frame 7. A limiting plate 12 is fixedly connected to the surface of the connecting blocks 10 via a connecting rod 11. A sliding plate 13 is slidably connected to the outer wall of the connecting rod 11. A return spring 14 is sleeved on the outside of the connecting rod 11, and the return spring 14 abuts against the sliding plate 13 and the limiting plate 12. A pull ring is fixedly connected to one side of the sliding plate 13, and an insertion rod 16 is fixedly installed on the other side of the sliding plate 13. Slots for the insertion rod 16 are provided on the surfaces of both the positioning frame 7 and the insertion plate 6. When it is necessary to fix the upper clamp 1 and the lower clamp 2, simply pull the pull ring first. At this time, the pull ring will drive the sliding plate 13 to... The outer wall of the connecting rod 11 moves synchronously. During the movement of the slide plate 13, the return spring 14 is squeezed. The slide plate 13 also drives the insertion rod 16 to move synchronously. At this time, the upper pipe clamp 1 and the lower pipe clamp 2 are closed. When the insertion plate 6 is inserted into the positioning frame 7, the pull ring is released. At this time, the return spring 14 is reset, driving the slide plate 13 and the insertion rod 16 to move synchronously. When the insertion rod 16 is inserted into the slot on the surface of the insertion plate 6, the insertion plate 6 and the positioning frame 7 can be fixed. At this time, the upper pipe clamp 1 and the lower pipe clamp 2 can be closed and fixed, so that the whole device can be fixedly installed at the leaking part of the pipeline.

[0037] In one embodiment, such as Figure 3 and Figure 4As shown, both connecting rods 11 are fitted with bellows protective covers 15. The two ends of the bellows protective covers 15 are fixedly connected to the opposite side of the slide plate 13 and the limiting plate 12, respectively. By setting the bellows protective covers 15, the return spring 14 can be effectively protected, thereby effectively extending the service life of the return spring 14, and without affecting the normal use effect of the return spring 14.

[0038] In one embodiment, such as Figures 1-4 As shown, both return springs 14 are made of stainless steel. Stainless steel has good corrosion resistance, so the return springs 14 also have good corrosion resistance, which can further extend the service life of the return springs 14.

[0039] In one embodiment, such as Figure 3 and Figure 4 As shown, multiple support blocks 17 are fixedly connected to the surface of the positioning frame 7. A guide rod 18 is fixedly connected between every two support blocks 17. A guide frame 19 is symmetrically slidably connected to the outer wall of the guide rod 18. The surface of the guide frame 19 is fixedly connected to the surface of the slide plate 13. During the movement of the slide plate 13, the guide frame 19 will also move synchronously on the outer wall of the guide rod 18. At this time, the guide frame 19 and the guide rod 18 can effectively play a limiting and guiding role, thereby effectively improving the stability of the slide plate 13 and the insertion rod 16 during the movement.

[0040] In one embodiment, such as Figure 1 As shown, rubber sealing gaskets 4 are bonded to the inner walls of both the upper pipe clamp 1 and the lower pipe clamp 2. The setting of rubber sealing gaskets 4 can effectively improve the sealing performance between the upper pipe clamp 1 and the lower pipe clamp 2 and the pipeline, thereby further improving the overall leakage protection effect of the device on the pipeline.

[0041] The above embodiments disclose a leak-proof pipe connection assembly. When leak protection is required for a leaking pipe, simply place the lower pipe clamp 2 and the upper pipe clamp 1 at the leaking location, and then close the upper pipe clamp 1 and the lower pipe clamp 2 using the hinge 3. After the upper pipe clamp 1 and the lower pipe clamp 2 are closed, the upper pipe clamp 1 and the lower pipe clamp 2 are fixed by the cooperation between the pull ring and the insertion rod 16. At this point, the entire device can be fixedly installed at the leaking location of the pipe. The cooperation between the upper pipe clamp 1, the lower pipe clamp 2, and the pressure relief valve 9 can provide leak protection for the pipe, effectively preventing shutdown accidents caused by minor leaks. This significantly improves the overall practicality of the device. The insertion plate 6 and the positioning frame 7 effectively provide positioning, making it easier for workers to position and connect the upper pipe clamp 1 and the lower pipe clamp 2, further enhancing the overall practicality and ease of use of the device.

[0042] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
