Description

Technical Field

[0001] This utility model relates to the field of pipeline protection technology, and in particular to a novel safety cover for leak-proof chemical pipelines. Background Technology

[0002] In the chemical industry, raw materials or products are generally transported between different reaction vessels through pipelines. However, the length of pipelines is limited, and multiple pipelines are usually connected by flanges. The flange rings are exposed to air for a long time, which may cause corrosion and affect the connection. Therefore, a new type of leak-proof chemical pipeline safety cover is proposed. Utility Model Content

[0003] The present invention aims to solve the technical problems existing in the prior art and provide a new type of safety cover for leak-proof chemical pipelines.

[0004] To achieve the above objectives, this utility model adopts the following technical solution, including an installation collar, which is assembled from two half-rings of corresponding sizes. An anti-slip pressure rubber pad is installed inside the installation collar. A fixed base is fixedly installed at the center of both the upper and lower surfaces of the installation collar. Outwardly bent connecting plates are fixedly installed at the ends of both sides of the installation collar. Connecting threaded grooves for locking are opened inside the connecting plates. A protective cover one and a protective cover two are provided between the corresponding two sets of installation collars. The inner diameter of the protective cover one and the protective cover two is larger than the outer diameter of the installation collar. The protective cover one and the protective cover two, when combined, form a cylinder. The opening size of the cylinder on both sides of the protective cover one and the protective cover two corresponds to the inner diameter of the installation collar. Limiting strips are fixedly installed on the inner side walls of the protective cover one and the protective cover two. The limiting strips are inverted L-shaped long strips. Moisture-proof installation inserts are inserted between corresponding two limiting strips.

[0005] Furthermore, the upper and lower end walls of the protective cover are provided with equally spaced docking slots, and the interior of the docking slots is provided with locking holes that connect to the surface of the protective cover.

[0006] Furthermore, equidistant access blocks are fixedly installed on both the upper and lower end walls of the second protective cover, and the access blocks have through holes corresponding to the inner diameter of the locking socket.

[0007] Furthermore, each end of the mounting plate has a pull-out insertion hole at its center. After the protective cover one and the protective cover two are combined, the insertion block is inserted into the corresponding docking slot.

[0008] Furthermore, the fixed base has a mating hole inside, the inner diameter of which corresponds to the inner diameter of the locking hole, and a locking column is inserted and fixed between the two corresponding fixed bases.

[0009] This utility model provides a novel leak-proof safety cover for chemical pipelines, which has the following beneficial effects:

[0010] 1. A novel leak-proof safety cover for chemical pipelines, comprising two protective covers, a first protective cover and a second protective cover. When combined, the first and second protective covers form a hollow cylinder. The openings on both sides of the combined cover correspond to the size of the pipe insertion port for the mounting rings. During installation, the two mounting rings are fitted onto the outside of the pipe. The two mounting rings are then moved closer together at the flange ring connection. The first and second protective covers are then fitted onto the outside of the flange ring. Two locking posts are inserted sequentially between the corresponding sets of fixed bases. The locking posts penetrate the mating slot and the insertion block to secure the assembly of the first and second protective covers. The first and second protective covers enclose the connection points of the two sets of pipe flange rings, preventing the connection points from being exposed and delaying corrosion, thus greatly improving the protective effect of the device.

[0011] 2. A novel leak-proof safety cover for chemical pipelines, featuring moisture-proof mounting plates. After mounting rings are fitted onto the outside of the pipeline, bolts are inserted into the connecting plates on both sides of the mounting rings. During the clamping process, the mounting rings bring the pressure rubber pads into contact with the pipeline surface, preventing slippage after installation. After two sets of mounting rings are fitted, the first and second protective covers are combined and fitted onto the flange ring connection of the pipeline. The combined protective covers are positioned by the two sets of mounting rings. The mounting plates installed inside the first and second protective covers keep their interiors dry. The pressure rubber pads inside the two mounting rings reduce external moisture entering the interiors of the first and second protective covers. Simultaneously, the two mounting plates increase the dryness of the air inside the first and second protective covers. Furthermore, the flange ring connection is protected from external collisions under the protection of the first and second protective covers, improving the protection effect after pipeline connection.

[0018] A new type of leak-proof safety cover for chemical pipelines, such as Figures 1 to 3 As shown, the device includes a mounting collar 1, which is assembled from two corresponding half-rings. An anti-slip rubber pad 13 is installed inside the mounting collar 1. A fixed base 2 is fixedly installed at the center of both the upper and lower surfaces of the mounting collar 1. Outwardly bent connecting plates 3 are fixedly installed at the ends of both the left and right sides of the mounting collar 1. Connecting threaded grooves 14 for locking are opened inside the connecting plates 3. A protective cover 4 and a protective cover 5 are provided between the corresponding two sets of mounting collars 1. The inner diameter of the second cover 5 is larger than the outer diameter of the mounting collar 1. The first cover 4 and the second cover 5 are combined to form a cylinder. The openings on both sides of the cylinder of the first cover 4 and the second cover 5 correspond to the inner diameter of the mounting collar 1. Limiting strips 9 are fixedly installed on both sides of the inner walls of the first cover 4 and the second cover 5. The limiting strips 9 are inverted L-shaped long strips. A moisture-proof mounting plate 10 is inserted between the two corresponding limiting strips 9. An activated carbon plate is bonded in the mounting plate 10 to absorb moisture from the air.

[0019] The upper and lower end walls of the protective cover 4 are provided with equidistantly arranged docking slots 6. Locking holes 7, which connect to the surface of the protective cover 4, are provided through the interior of each docking slot 6. The upper and lower end walls of the protective cover 5 are fixedly equipped with equidistantly arranged access blocks 8. The interior of each access block 8 has a through hole corresponding to the inner diameter of the locking hole 7. Pull-out holes 11 are provided at the center of both ends of the mounting plate 10. The mounting plate 10, which is inserted into the two limiting strips 9, can be pulled out through the pull-out holes 11. After the protective cover 4 and the protective cover 5 are combined, the access blocks 8 are inserted into the corresponding docking slots 6.

[0020] The fixed base 2 has a mating hole 12 inside, and the inner diameter of the mating hole 12 corresponds to the inner diameter of the locking hole 7. A locking column 15 is inserted and fixed between the two fixed bases 2. The protective cover 1 4 and the protective cover 2 5 are combined and fitted onto the outside of the flange ring connection. The locking column 15 passes through the two fixed bases 2 and through the mating slot 6 and the access block 8. The two locking columns 15 lock the protective cover 1 4 and the protective cover 2 5 onto the outside of the flange connection. After the protective cover 1 4 and the protective cover 2 5 are assembled, they wrap the flange connection to prevent contact with the outside air.

[0021] The working principle of this utility model:

[0022] By installing protective covers 4 and 5, which are equipped with additional protection, a hollow cylinder is formed when the two covers are combined. The size of the openings on both sides of the combined protective covers 4 and 5 corresponds to the size of the pipe insertion port of the mounting ring 1. During installation, after the two mounting rings 1 are fitted onto the outside of the pipe, they are moved closer to each other on both sides of the flange ring connection. Then, the protective covers 4 and 5 are combined and fitted onto the outside of the flange ring. The two locking posts 15 are inserted into the corresponding two sets of fixed bases 2 in sequence. The locking posts 15 pass through the docking slot 6 and the insertion block 8 to fix the assembly of the protective covers 4 and 2. The protective covers 4 and 25 enclose the connection of the two sets of pipe flange rings, preventing the connection from being exposed and delaying the occurrence of corrosion, thus greatly improving the protection effect of the device.

[0023] By installing mounting plates 10 for moisture protection, the mounting collar 1 is fitted onto the outside of the pipe. After bolts are inserted into the connecting plates 3 on both sides of the mounting collar 1, the mounting collar 1 clamps the outside of the pipe, causing the pressure rubber pad 13 to contact the pipe surface, making it difficult for the mounting collar 1 to slip after it is fitted. After the two sets of mounting collar 1 are fitted, the protective cover 1 4 and the protective cover 2 5 are combined and fitted onto the flange ring connection of the pipe. The protective cover 1 4 and the protective cover 2 5 are positioned by the two sets of mounting collar 1. The mounting plates 10 installed inside the protective cover 1 4 and the protective cover 2 5 will keep the internal space of the protective cover 1 4 and the protective cover 2 5 dry. The pressure rubber pads 13 set inside the two mounting collar 1 reduce the entry of external moisture into the interior of the protective cover 1 4 and the protective cover 2 5. At the same time, the two mounting plates 10 improve the dryness of the air inside the protective cover 1 4 and the protective cover 2 5. Under the protection of the protective cover 1 4 and the protective cover 2 5, the flange ring connection can avoid external collisions, improving the protection effect after the pipe connection.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
