[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0020] In order to improve the sealing between two anti-corrosion pipes, refer to Figure 1 、 Figure 2 and Figure 3As shown, it includes an upper flange 1 and a lower flange 2 for connecting two anti-corrosion pipes, the upper flange 1 and the lower flange 2 are connected by bolts 3, an anti-corrosion gasket 4 is provided between the upper flange 1 and the lower flange 2, the anti-corrosion gasket 4 includes an upper gasket 5 and a lower gasket 6, and a splicing component is provided between the upper gasket 5 and the lower gasket 6. When the two connected anti-corrosion pipes are connected, the convex portion 7 and the concave portion 8 on the upper gasket 5 and the lower gasket 6 are aligned, and the limit plate 12 is pulled. As the spring 11 is stretched, the limit plate 12 exceeds the length of the slide rail 14. At this time, the column is 9 is inserted into the slide rail 14. When the limit plate 12 moves into the limit groove 13, the protrusion 7 is completely inserted into the recess 8, and the upper gasket 5 and the lower gasket 6 are spliced together. After loosening the limit plate 12, the spring 11 is deformed and pulls the limit plate 12 toward the column 9, so that the limit plate 12 is clamped in the limit groove 13, and the spliced upper gasket 5 and lower gasket 6 are fixed, thereby improving the stability of the anti-corrosion gasket 4 after splicing. Then, the two pipes are connected to the upper flange 1 and the lower flange 2 respectively, and the splicing of the two anti-corrosion pipes can be sealed and anti-corrosion treated through the anti-corrosion gasket 4.
[0021] In order to improve the stability of the upper gasket 5 and the lower gasket 6 after splicing, refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the upper gasket 5 has protrusions 7 extending outward on both sides toward the lower gasket 6, and the surface of the lower gasket 6 is provided with a recess 8 adapted to the protrusion 7. The protrusion 7 is adapted to the recess 8. As the protrusion 7 is inserted into the recess 8, the upper gasket 5 and the lower gasket 6 can be spliced together, which is highly practical and allows the anti-corrosion gasket 4 to be disassembled and replaced as a whole. The splicing assembly includes a column 9 provided on the upper surface of the recess 8, and the upper surface of the column 9 is provided with a hole groove 10 facing inward. A spring 11 is provided in the hole groove 10. When the column 9 is inserted into the slide rail 14 through the notch 15, the limit plate 12 is pulled, and the spring 11 is stretched, so that the limit plate 12 extends beyond the slide rail 14, driving the movement of the column 9, allowing the column 9 to slide into the limit groove 13. The limit groove 13 is connected to the slide rail 14. The end of the spring 11 away from the hole 10 is connected to the limit plate 12 through the opening of the hole 10. The limit plate 12 is circular and can be clamped into the limit groove 13 on both sides of the limit plate 12 to fix the connected upper gasket 5 and the lower gasket 6, thereby improving the stability of the anti-corrosion gasket 4 after splicing. The upper surface of the protrusion 7 is provided with a limit groove 13. The limit groove 13 is provided with a slide rail 14 vertically downwardly adapted to the column 9. As the column 9 slides along the length of the slide rail 14 in the slide rail 14, the limit plate 12 can be driven to be inserted into the limit groove 13, completing the splicing of the upper gasket 5 and the lower gasket 6. The slide rail 14 is provided with a notch 15 for the column 9 to be inserted into the side facing the recess 8. The column 9 can be inserted into the slide rail 14 through the notch 15 and moved into the limit area of the limit groove 13. The upper gasket 5 and the lower gasket 6 are symmetrically arranged in the upper and lower parts.
[0022] When in use, first, when connecting the two anti-corrosion pipes, align the convex part 7 and the concave part 8 on the upper gasket 5 and the lower gasket 6, pull the limit plate 12, and as the spring 11 stretches, the limit plate 12 exceeds the length of the slide rail 14. At this time, the column 9 is inserted into the slide rail 14 through the notch 15. When the limit plate 12 moves to the limit groove 13, the convex part 7 is fully inserted into the concave part 8, and the upper gasket 5 and the lower gasket 6 are spliced together. After loosening the limit plate 12, the spring 11 deforms and pulls the limit plate 12 toward the column 9, so that the limit plate 12 is clamped in the limit groove 13, fixing the spliced upper gasket 5 and lower gasket 6, improving the stability of the spliced anti-corrosion gasket 4, and then connecting the two pipes to the upper flange 1 and the lower flange 2 respectively, and the splicing of the two anti-corrosion pipes can be sealed and anti-corrosion treated through the anti-corrosion gasket 4.
