Description

Technical Field

[0001] This utility model relates to the field of chemical pipeline protection technology, specifically a protective cover for the connection of a surfactant production pipeline. Background Technology

[0002] Surfactant production pipeline connection guards are a type of safety protection equipment specifically designed for flange connections in chemical pipelines. They are primarily used to prevent splashing accidents caused by corrosion, seal failure, or media leakage, and are an important component of industrial safety.

[0003] Chinese patent CN221348406U discloses a protective cover for the connection of a surfactant production pipeline. It includes a fixed pressure plate, an adjusting shaft, a locking band, a sealing ring, and a pipeline. A sealing ring is provided on the outer wall of the pipeline connection, and a locking band is provided on one side of the sealing ring. A fixed pressure plate is provided at each end of the sealing ring, and an adjusting shaft is provided between the fixed pressure plates. This invention, by placing the sealing ring at the pipeline connection, rotates the rotating shaft, causing screws I and II to drive the internal threaded lugs, making the fixed pressure plates move in opposite directions in a linear motion, applying pressure to the inclined section. The locking band is tightened by a locking bolt. Rotating the set screw compresses the inner lining ring, which in turn applies pressure, compressing the spring and thus applying pressure to the sealing ring. This improves the sealing effect of the sealing ring at the pipeline connection, preventing leakage and improving the safety of chemical production.

[0004] The aforementioned protective cover enhances the sealing of pipe connections. However, in actual applications, surfactants often leak from the side of the connection, and pressure alone is insufficient to meet the sealing requirements of pipes under long-term shaking or impact. Furthermore, existing protective covers only use locking bolts and pressure plates for tightening, which may result in uneven force distribution. This not only fails to promote the sealing of pipe connections but also exacerbates surfactant leakage. Therefore, a protective cover for surfactant production pipe connections is needed. Utility Model Content

[0005] The purpose of this utility model is to provide a protective cover for the connection of surfactant production pipelines, so as to solve the problems that existing protective covers cannot adjust the tightness of the sealing ring, and that uneven force during clamping leads to poor sealing effect of pipeline connection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective cover for the connection of a surfactant production pipeline, comprising two flanged pipelines, with a reinforcing mechanism provided between the two flanged pipelines; the reinforcing mechanism includes two flange buckles, which are fastened to both sides of the two flanged pipelines, and each side of the flange buckle has an insert hole through which a connecting screw assembly is fixedly installed; each side of the flange buckle has three reinforcing internal threads, and a reinforcing bolt is threaded onto the reinforcing internal threads.

[0007] Preferably, the flange buckle has a U-shaped cross-section, and the flange end on the flange pipe is embedded inside the flange buckle.

[0008] Preferably, the three reinforcing internal threads are equidistantly provided on one side of the flange, and the reinforcing internal threads are perpendicular to the flange end on the flange pipe.

[0009] Preferably, the reinforcing bolts on both sides are opposite each other, and the arc of both flange buckles is 175°.

[0010] Preferably, a sealing mechanism is provided between the flange and the flange pipe. The sealing mechanism includes six pressure-applying internal threads, which are respectively opened on two flanges. Pressure-applying bolts are threaded on the pressure-applying internal threads. A rubber gasket is fastened and installed on the flange. Two limiting protrusions are fixedly installed on one side of the rubber gasket, and sealing protrusions are fixedly installed on both ends of the rubber gasket.

[0011] Preferably, the three pressure-applying internal threads are equidistantly provided on the flange, and all the pressure-applying internal threads point to the center of the flange.

[0012] Preferably, the curvature of the rubber pad is 180°, the inner wall of the flange buckle has two grooves, and the limiting protrusion is adapted to the grooves.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) The protective cover for the connection of the surfactant production pipeline controls the two flanges to be fastened to each other on both sides of the flange pipeline connection. Benefiting from the shape and curvature of the flanges, two reinforced internal threads are used to achieve the initial connection between the flanges and the flange pipeline. When in use, the connecting screw group is embedded in the reinforced internal threads and adjusted as needed, so that the connecting screw group is precisely pressed on the parts of the pipeline connection that are prone to leakage.

[0015] 2) The surfactant is used to produce a protective cover for pipe connections. Before connecting the flange, a rubber gasket is fastened to the flange, so that the rubber gasket can be clamped between the flange pipe and the flange. Benefiting from the orientation of the internal thread of the pressure, when in use, the pressure bolts at the easily leaking parts of the pipe edge are controlled according to the needs, so that the rubber gasket is vertically pressed on the flange pipe under the action of the pressure bolts, so as to achieve a precise sealing effect at the pipe connection.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Combination Figures 1-3A protective cover for the connection of a surfactant production pipeline includes two flanged pipes 1, and a reinforcing mechanism 2 is provided between the two flanged pipes 1. The reinforcing mechanism 2 includes two flange buckles 201, which are fastened to both sides of the two flanged pipes 1. Each side of the flange buckle 201 has an insertion hole 202, through which a connecting screw assembly 203 is fixedly installed. Each side of the flange buckle 201 has three reinforcing internal threads 204, and a reinforcing bolt 205 is threaded on the reinforcing internal threads 204.

[0025] The flange buckle 201 has a U-shaped cross-section. The flange end on the flange pipe 1 is embedded inside the flange buckle 201. The flange buckle 201, together with the connecting screws 203 on both sides, achieves the initial fixation of the two flange pipes 1. Three reinforcing internal threads 204 are equidistantly opened on one side of the flange buckle 201, and the reinforcing internal threads 204 are perpendicular to the flange end on the flange pipe 1. The reinforcing bolts 205 on both sides are opposite to each other. Further control of the reinforcing bolts 205 on both sides can apply pressure to the two flange pipes 1, thereby achieving the reinforcement effect at the pipe connection. The curvature of the two flange buckles 201 is 175° to avoid the flange buckle 201 having a large curvature that would cause a gap between the flange pipe 1 and the flange buckle 201.

[0026] Example 2

[0027] See Figure 4 and Figure 5 A sealing mechanism 3 is provided between the flange buckle 201 and the flange pipe 1. The sealing mechanism 3 includes six pressure-applying internal threads 301, which are respectively opened on two flange buckles 201. Pressure-applying bolts 302 are threaded on the pressure-applying internal threads 301. A rubber gasket 303 is fastened and installed on the flange buckle 201. Two limiting protrusions 304 are fixedly installed on one side of the rubber gasket 303, and sealing protrusions 305 are fixedly installed on both ends of the rubber gasket 303.

[0028] Three pressure-applying internal threads 301 are equidistantly provided on the flange buckle 201, and all pressure-applying internal threads 301 point to the center of the flange buckle 201, ensuring that the pressure-applying internal threads 301 apply vertical pressure to a local position on the rubber gasket 303 at the connection of the flange pipe 1. The curvature of the rubber gasket 303 is 180°, and the two sealing protrusions 305 make the connection between the two rubber gaskets 303 tighter. Two grooves are provided on the inner wall of the flange buckle 201, and the limiting protrusion 304 is adapted to the grooves, which can prevent the rubber gasket 303 from shifting or falling off during the installation of the flange buckle 201.

[0029] In actual operation, by controlling the two flange buckles 201 to be snapped onto both sides of the flange pipe 1 connection, and taking advantage of the shape and curvature of the flange buckles 201, two reinforcing internal threads 204 are used to achieve the initial connection between the flange buckles 201 and the flange pipe 1. When in use, the connecting screw group 203 is embedded and adjusted in the reinforcing internal threads 204 as required, so that the connecting screw group 203 is precisely pressed on the part of the pipe connection that is prone to leakage.

[0030] Before connecting the flange buckle 201, the rubber gasket 303 is fastened into the flange buckle 201, so that the rubber gasket 303 can be clamped between the flange pipe 1 and the flange buckle 201. Benefiting from the orientation of the pressure internal thread 301, during use, the pressure bolt 302 at the easily leaking part of the pipe edge is controlled according to the needs, so that the rubber gasket 303 is vertically pressed on the flange pipe 1 under the action of the pressure bolt 302, so as to achieve a precise sealing effect at the pipe connection.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
