[0002] In chemical plants, raw material pipelines are connected by flanges. When transporting corrosive chemicals such as hydrochloric acid, protective covers are typically used to prevent splashing of the chemical solution at the flange connections. For example, Chinese patent CN212107476U discloses a flange splash guard, which includes an annular protective strip. The flange is located inside the annular protective strip, and both ends of the annular protective strip are fixed with fixing plates perpendicular to the strip. The fixing plates are square and have bolt holes, studs, and nuts that mate with the bolt holes.
[0003] For the aforementioned existing technologies, since the flange sizes used in different pipelines are not necessarily the same, and the inner diameter of the above protective structure cannot be adjusted according to the change of the outer diameter of the flange, multiple sets of splash-proof structures of different sizes need to be manufactured accordingly, resulting in poor versatility.

[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. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0029] To address the technical problem that the inner diameter of the protective structure cannot be adjusted according to changes in the outer diameter of the flange, this utility model provides a flange connection splashproof structure. This structure allows for the wrapping of a protective cloth around the flange connection, making it suitable for flanges of different outer diameters. After wrapping, fasteners are used to secure the fabric and prevent loosening. A tie assembly further secures the upper and lower ends, allowing for tightening to match different pipe diameters. This design offers high versatility, can be used for splashproof wrapping at flange connections of various outer diameters, and is low in manufacturing cost, with a structure that is easy to disassemble and replace.
[0030] It should be noted that the flange connection splash-proof structure described in this utility model is used for, but not limited to, covering and splash-proofing at flange connections. For ease of explanation, this utility model only uses the application of the flange connection splash-proof structure to cover and splash-proofing at flange connections as an example. The principle of the flange connection splash-proof structure applied to other types of equipment is essentially the same as the principle of its application to cover and splash-proofing at flange connections, and will not be elaborated here.
[0031] Please see Figure 1 , Figure 1 This is a three-dimensional view of the flange connection splash-proof structure covering the flange connection in one embodiment of the present invention. The flange connection splash-proof structure includes a covering component 1, a fastener 2, and a fastening assembly 3. The covering component 1 includes a covering cloth 11 and a connecting component 12. The connecting component 12 is disposed on one side of the covering cloth 11, forming a gap 101 between itself and the side edge of the covering cloth 11, allowing the other side of the covering cloth 11 to pass through. This ensures that when the covering cloth 11 is wrapped around the flange connection, its other end passes through the gap 101 and partially overlaps with the covering cloth 11. In use, the covering cloth 11 is first placed at the flange connection, then wrapped around the flange connection once, with the other end passing through the gap. 101. Wrap the covering cloth 11 around the flange connection and tighten it so that the covering cloth 11 is wrapped around the flange connection in a partially overlapping ring. The fastener 2 is provided on the connecting assembly 12 and has a fastening end that can clamp the covering cloth 11. When the covering cloth 11 is wrapped around the flange connection in a ring and partially overlapping manner, the fastener 2 clamps the overlapping part of the covering cloth 11 to prevent the wrapping from coming loose. The tie assembly 3 is retractable and looped on the outside of the covering cloth 11. It is used to tie the upper or lower end of the covering cloth 11 in the wrapped state, specifically to tie the outer periphery of the upper and lower halves. The tie assembly 3 can be a tie, wire or binding tape, which can be used to tie and tighten the rolled covering cloth 11.
[0032] In this embodiment, the covering cloth 11 is used for splash-proof pipe flange connections as needed. Different types of raw materials are used depending on the type of material being transported. For example, for routine hydrochloric acid contact, polyester fiber is used, and high-density fabric is selected, with regular wear checks; for high-concentration hydrochloric acid or high-temperature environments, PTFE-coated cloth / fluorosilicone microfiber cloth is used; for low-cost protection requirements, polypropylene fiber is used to avoid high-temperature use and provides good short-term protection; for long-term exposure or high-risk environments, coated polyester cloth / PTFE lining is used, combining coating technology to improve the protection level, with safety as the priority.
[0033] Understandably, the material used for the covering cloth 11 can be adjusted according to actual needs, and there is no single limitation here. The covering cloth 11 only needs to have the flexibility of fabric, that is, to be rolled up and wrapped to the flange connection, and the upper and lower ends can be tied to the outside of the pipeline by the tie assembly 3.
[0034] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 3 In order to allow for individual replacement of the covering fabric 11 when it is damaged, the connecting component 12 includes a connecting structure 121 and a connecting strap 122. Each end of the connecting strap 122 is connected to a connecting structure 121. The fasteners 2 are correspondingly installed at both ends of the connecting structure 121, so that the two sides of the covering fabric 11 are detachably connected to the connecting structure 121. By separating the connecting structure 121 from the covering fabric 11, the covering fabric 11 can be replaced individually.
[0035] In this embodiment, since a gap is formed between the covering cloth 11 and the connecting component 12, the covering cloth 11 passes through the gap. The connecting strip 122 of the connecting component 12 is located on the outer side of the covering cloth 11 away from the flange connection. The covering cloth 11 provides protection at this location; that is, sputtering first affects the covering cloth 11. Only when the covering cloth 11 is damaged, and the damaged area is located at the connecting strip 122, is there a probability of interference with the connecting strip 122. The connecting structural members 121 at both ends are located above and below the flange connection and are not easily sputtered. Therefore, the covering cloth 11 and the connecting component 12 are detachably connected, which facilitates the replacement of the easily damaged covering cloth 11. Since the connecting component 12 is not easily damaged, it does not need to be replaced frequently, thus saving costs.
[0036] In one embodiment, please refer to Figure 1 and Figure 4 To facilitate connection with one side of the covering fabric 11 and to clamp the other side of the covering fabric 11, the connecting structure 121 includes a first connecting end 121a and a second connecting end 121b. One side of the first connecting end 121a is connected to the second connecting end 121b. The gap 101 is located between the first connecting end 121a and the second connecting end 121b. Both the first connecting end 121a and the second connecting end 121b are provided with slots 121c through which the covering fabric 11 passes. The fasteners 2 are correspondingly provided on the first connecting end 121a and the second connecting end 121b to clamp the covering fabric 11 in the slots 121c.
[0037] In this embodiment, one side of the covering fabric 11 is inserted into the slot 121c of the first connecting end 121a, such as... Figure 3As shown, and clamped by fastener 2, a detachable connection is formed. The side of the covering fabric 11, the connecting strap 122, and the two connecting structures 121 form a gap 101. During the wrapping process, the other side of the covering fabric 11 is inserted into the slot 121c of the second connecting end 121b, and further penetrates the gap 101, as shown. Figure 2 As shown; after tightening and wrapping it to the flange connection, the covering cloth 11 is clamped through the slot 121c area of the second connection end 121b by the fastener 2.
[0038] In one embodiment, please refer to Figure 1 and Figure 4 To facilitate clamping and loosening, the fastener 2 includes a locking bolt 21, which is threaded onto the first connecting end 121a or the second connecting end 121b and extends through the first connecting end 121a or the second connecting end to the inner side of the corresponding slot 121c. By tightening the locking bolt 21, the covering cloth 11 is pressed into the slot 121c, thus forming a clamping connection.
[0039] It is understandable that fastener 2 can also be an elastic clip, which uses elasticity to press the covering cloth 11 into the slot 121c. This will not be elaborated on here, nor is it the only limitation.
[0040] Furthermore, in order to improve the tightness of the clamping, a groove 121d is provided on the inner wall of the slot 121c on the side opposite to the locking bolt 21, which presses the covering cloth 11 into the groove 121d to make the clamping more secure.
[0041] Furthermore, in order to improve the anti-slip performance, an anti-slip layer is provided in the groove 121d to prevent the covering cloth 11 from slipping when clamped.
[0042] In one embodiment, please refer to Figure 1 To facilitate the formation of a wrapping and partial overlap, and to avoid the overlapping portion obstructing the fastener 2, the covering fabric 11 includes a first fabric body 11a and a second fabric body 11b. The width of the second fabric body 11b is smaller than that of the first fabric body 11a. The first fabric body 11a is used to form a gap 101 with the connecting component 12, and the second fabric body 11b is used to penetrate the gap 101. The width of the second fabric body 11b is smaller than that of the gap 101, making it easier to insert into the inside of the gap 101 and facilitating operation.
[0043] Furthermore, the length of the second connecting end 121b is greater than that of the first connecting end 121a. In the covered state, the second fabric 11b passes through the slot 121c on the second connecting end 121b, and the first fabric 11a is inserted into the slot 121c on the first connecting end 121a. The second fabric 11b, which is rolled up and overlapped, is smaller in width than the first fabric 11a. It matches the position of the second connecting end 121b and can be located between the two first connecting ends 121a, avoiding obstruction of the first connecting ends 121a and the fastener 2, which facilitates the subsequent disassembly and assembly of the locking bolt 21.
[0044] In one embodiment, please refer to Figure 1 and Figure 2 To provide a feasible tying method, the tying assembly 3 includes a strap body 31, a hook and loop fastener A side 32, and a hook and loop fastener B side 33. The hook and loop fastener A side 32 and the hook and loop fastener B side 33 are respectively disposed at both ends of the strap body 31. In the covering state, the hook and loop fastener A side 32 and the hook and loop fastener B side 33 are bonded together. By wrapping the strap body 31 around the outside of the covering fabric 11 and bonding the hook and loop fastener A side 32 and the hook and loop fastener B side 33, the covering fabric 11 can be tied up, and the upper end is tightened on the pipeline.
[0045] Understandably, since the diameter of the pipe is generally smaller than the diameter of the flange, it is only necessary to tie the upper end tightly to form a closed end, which can be hung on the pipe flange connection from top to bottom to form a splash-proof protection covering the outside of the flange.
[0046] Furthermore, in order to provide a more stable installation effect, there are two belt bodies 31, and one end of each belt body 31 is fixedly connected to the connecting belt 122, so that both ends can be tied to the pipes at both ends of the flange connection to prevent slippage.
[0047] Understandably, when both ends are tightened, the flange position is not limited to top to bottom, and the above structure can also be used for horizontal flanges; the belt body 31 is fixed on the connecting belt 122 for easy overall carrying, and a split design can also be adopted.
[0048] To better understand this utility model, the following is combined with... Figures 1 to 4The technical solution of this utility model is described in detail as follows: The upper and lower corners of one side of the covering cloth 11 are inserted into the slots 121c of the first connecting end 121a of the two connecting structural members 121, and locked with the locking bolts 21 to form a gap 101; then the other side of the covering cloth 11 is rolled up and wrapped around the outer periphery of the flange connection, and inserted into the slot 121c of the second connecting end 121b of the connecting structural member 121, and continues to penetrate the gap 101, the covering cloth 11 is pulled tight to wrap around the outside of the flange connection, and the locking bolts 21 on the second connecting end 121b are locked; finally, the tape body 31 is tied to the outside of the covering cloth 11 and glued with a Velcro structure, the upper and lower ends of the covering cloth 11 are closed and tied tightly to the upper and lower pipelines.
[0049] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
