[0002] Chemical products are one of the most commonly used products in chemical production enterprises. Chemical products need to be transported through flange-connected pipelines during use. During use, gasket corrosion and loose flange bolts often occur at the flange connections on the chemical pipelines, causing the flanges to spray outward with chemicals. In mild cases, it can cause skin damage to personnel, while in severe cases, people may fall into a coma or suffer shock, requiring emergency treatment. The splashed chemicals can also cause serious corrosion to the production equipment and accessories near the loose flanges, reducing the service life of the equipment. In severe cases, new equipment and accessories need to be replaced, and production must be stopped for replacement, seriously affecting the stable operation of production.

[0003] Existing protective covers, such as a flange protective cover with patent number CN2110082515U, can prevent chemicals from splashing, but the connection of the protective cover is fixed by Velcro and fixed with a tie band. When splashing, the protective cover only serves to shield, especially when the flange is installed vertically, the splashed liquid can easily seep out from the connection, resulting in the protective cover having no liquid storage function. The splashed chemicals will still leak out of the protective cover, which not only causes a waste of resources, but also the leaked chemicals will fall on the surrounding production equipment or accessories, causing corrosion to them.

[0017] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0018] like Figure 1-4 As shown, the utility model provides a novel anti-corrosion chemical product pipeline interface protective sleeve, comprising a pipeline 1, a half shell 1 2 and a half shell 2 3, one side of the half shell 1 2 and the half shell 2 3 are connected by a hinge, a collecting groove 4 is provided below the half shell 1 2 and the half shell 2 3, both ends of the collecting groove 4 are fixedly connected with a semicircular partition 5, a semicircular hole 6 for accommodating the pipeline 1 is provided at the axis of the half shell 1 2 and the half shell 2 3, and a semicircular sleeve is provided on the semicircular hole 6 below the half shell 1 2 and the half shell 2 3 1, a semicircular sealing strip 8 is provided on the inner wall of the sleeve 1 7, a semicircular sleeve 2 9 is provided on the semicircular hole 6 on the upper side of the half shell 1 2 and the half shell 2 3, and a fixing piece for fixing the sleeve 2 9 to the pipeline 1 is provided on the sleeve 2 9, the partition 5 on the collecting tank 4 of the half shell 1 2 is recessed into the collecting tank 4, and the partition 5 on the collecting tank 4 of the half shell 2 3 is protruded out of the collecting tank 4, the partition 5 on the collecting tank 4 of the half shell 1 2 is recessed into the collecting tank 4, and the partition 5 on the collecting tank 4 of the half shell 2 3 is protruded out of the collecting tank 4.

[0019] like Figure 1-4 As shown, the collecting tank 4, the half shell 1 2 and the half shell 2 3 are used to temporarily store the leaked chemicals to prevent them from flowing directly to the ground; the partition 5 on the collecting tank 4 of the half shell 1 2 is recessed into the collecting tank 4, and the partition 5 on the collecting tank 4 of the half shell 2 3 is protruded out of the collecting tank 4, and the recessed part and the protruding part are matched. When the half shell 1 2 and the half shell 2 3 are buckled together, the protruding part of the half shell 2 3 falls into the recessed part of the half shell 1 2, indirectly raising the gap at the connection between the collecting tank 4 of the half shell 1 2 and the half shell 2 3, further improving the sealing performance, and preventing the leaked chemicals from leaking to the outside from the connection gap of the protective sleeve; the half shell 1 2 and the half shell 2 3 are buckled together, and the protective sleeve is sleeved on the outer surface of the flange on the pipeline 1, as shown in FIG. Figure 3As shown, when the pipeline 1 is in a vertical state, the sealing strip 8 can improve the sealing between the sleeve 1 7 and the pipeline 1. If splashing occurs at the flange, the splashed liquid will fall into the collecting tank 4 along the inner walls of the half shell 1 2 and the half shell 2 3, wherein the partition plate 5 can prevent the liquid in the collecting tank 4 from penetrating into the connection below the half shell 1 2 and the half shell 2 3, causing the liquid in the collecting tank 4 to flow out. Similarly, Figure 4 As shown, when the flange is in a horizontal state, the splashed liquid will fall into half shell 1 2 or half shell 2 3.

[0020] The outer walls of the half shell 1 2 and the half shell 2 3 and the bottom of the collecting tank 4 are provided with flow guide holes, and a flow guide pipe 10 is installed on the flow guide hole, and a valve 11 is provided on the flow guide pipe 10.

[0021] like Figure 1 As shown, if the flange on the pipeline 1 leaks, the leaked chemicals are collected in the collection tank 4 or inside the half shell 1 2 or the half shell 2 3, and the chemicals can be discharged to a safe place in time through the diversion hole, the diversion pipe 10 and the valve 11.

[0022] The inner walls of the half shell 1 2 and the half shell 2 3 are fixedly connected with flanges 12 that match the gap at the flange connection, and a plurality of flow holes are opened on the side of the flange 12 close to the half shell 1 2 or the half shell 2 3.

[0023] like Figure 2 As shown, the flange 12 is made of rubber. When the half shell 1 2 and the half shell 2 3 are buckled together, the flange 12 acts as a sealing ring to improve the sealing performance of the flange connection. A flow hole is provided on the flange 12 to allow chemicals to flow in the half shell 1 2 or the half shell 2 3, so that all the chemicals in the half shell 1 2 or the half shell 2 3 can flow out through the guide hole.

[0024] The fixing member includes a plurality of limiting teeth 13 and limiting teeth 2 14 meshing with the limiting teeth 13 , the limiting teeth 13 are arranged on the inner wall of the sleeve 2 9 , and the limiting teeth 2 14 are arranged on the pipe 1 , and the limiting teeth 13 and the limiting teeth 2 14 are both made of rubber.

[0025] like Figure 1 and 2As shown, the protective sleeve wraps the flange. If there is a leak at the flange, the leaking direction is uncertain, so the leaked chemicals may cause the protective sleeve to rotate relative to the pipe 1 and the flange. If the flange is placed horizontally, the connecting gap of the protective sleeve rotates to the lowest point, resulting in the temporary storage point of the chemicals being located at the gap of the protective sleeve. The chemicals cause the chemicals to penetrate into the gap and flow out of the protective sleeve. The limit teeth 13 and the limit teeth 2 14 are meshed together, which can well fix the protective sleeve on the pipe 1 to prevent the protective sleeve from rotating, and the meshing limit teeth 13 and the limit teeth 2 14 also play a sealing role.

[0026] The other sides of the half shell 1 2 and the half shell 2 3 are connected by multiple sets of buckles 15 .

[0027] like Figure 1 As shown, the buckle 15 buckles the half shell 1 2 and the half shell 2 3 together, which can facilitate the removal or installation of the protective sleeve from the flange.

[0028] Principle of use: In the process of buckling the half shell 1 2 and the half shell 2 3 by the buckle 15, the protruding part of the partition 5 in the collecting tank 4 of the half shell 2 3 is engaged with the collecting tank 4 of the half shell 1 2, and the flange 12 falls into the flange connection. At the same time, the limiting tooth 13 on the sleeve 2 9 is meshed with the limiting tooth 2 14 on the pipeline 1, and the protective sleeve is sleeved on the outer surface of the flange. When the pipeline 1 is in a vertical state, the collecting tank 4 is at the bottom, and the splashed chemicals fall into the collecting tank 4 along the inner walls of the half shell 1 2 and the half shell 2 3, and the valve 10 on the guide pipe 9 on the collecting tank 4 is opened, and the half shell 1 or the half shell 2 or the half shell 3 is closed at the same time. The valve 10 on the guide pipe 9 on the second 3 is used to transport the chemicals falling into the collection tank 4 to a safe area along the guide pipe 10 for recovery; when the pipeline 1 is in a horizontal state, the middle of the half shell 1 2 or the half shell 2 3 is at the lowest point, and the splashed chemicals fall into the interior of the half shell 1 2 or the half shell 2 3 along the inner wall of the half shell 1 2 and the half shell 2 3 and are collected. At the same time, the valve 10 on the guide pipe 9 on the half shell 1 2 or the half shell 2 3 is opened, and the valve 10 on the guide pipe 9 on the collection tank 4 is closed, and the chemicals gathered in the half shell 1 2 or the half shell 2 3 flow into a safe place along its guide pipe 10 for recovery.

[0029] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
