Description

Technical Field

[0001] This utility model relates to the technical field of pipeline connection sealing components, and in particular to a sealing component for a desalination pipeline connection. Background Technology

[0002] Sealing rings for desalination pipelines are typically installed at the joints, usually between two pipes. The function of the sealing ring is to fill the gaps at the pipe joints through its elasticity, thereby achieving a seal and preventing leakage.

[0003] In existing technologies, the sealing rings for desalination pipelines are typically installed at the pipe socket. This is achieved by inserting one end of one pipe into the socket of another and installing a rubber ring between the two pipes. For example, Chinese Utility Model Patent No. CN222076791 U discloses a sewage pipe shredder, including a housing assembly, cutting blades, and a motor. The housing assembly includes an upper shell and a lower shell. An inlet flange is installed at the upper end of the upper shell, and an outlet flange is installed at the lower end of the lower shell. During use, when connecting pipelines to the inlet and outlet flanges, a sealing gasket needs to be installed on the flanges. Normally, the sealing gasket is annular and contacts the flange end faces, providing a seal between the two flanges. However, due to material aging, improper installation, or operational errors, the sealing gasket may shift or even misalign between the two flange end faces. This can damage or malfunction the seal, leading to leakage at the connection point, wasting resources and potentially causing environmental pollution.

[0004] Therefore, existing gaskets may become misaligned or displaced due to improper installation or operation, leading to leakage, contamination, and reduced sealing performance. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a sealing component for the connection of a desalination pipeline, which forms a comprehensive seal through the concave part of the body, the outer wall and the flanges on both sides.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A sealing element for a desalination pipeline connection includes a body, a recessed portion of which engages with a flange end face of the desalination pipeline, and an outer wall that engages with the end face of another flange. The surface of the body transmits the force of the other flange to the recessed portion. The recessed portion fills the threaded portion of the flange end face through deformation and is also used to fill the other flange end face through deformation of the outer wall.

[0008] Compared with the prior art, the present invention has the following advantages:

[0009] When another flange applies force to the body, the concave part of the body fills the entire space of the threaded part, while the outer wall fills the threaded space on the other flange. Through filling and sealing connection with the flanges on both sides, the concave part of the body and the flange fasten together to prevent liquid in the demineralized water pipeline from entering the gap between the body and the flange end face. The inner wall adheres to the inner wall of the flange to prevent liquid on the inner wall of the demineralized water pipeline from entering the body. The contact between the outer wall and the flange end face can transfer the force to the concave part through deformation, which can prevent liquid from seeping out between the two flanges. This achieves a comprehensive sealing method of sealing layer by layer from the inner wall of the flange and the flange end face, preventing the two flange end faces from shifting or misaligning and improving the sealing performance.

[0010] More preferably, the body includes:

[0011] The sealing ring, in the shape of an annulus, is mounted on a flange and is attached to the end face of the flange.

[0012] The first ring piece, in the shape of a ring, is set on the outer edge of the sealing ring and is integrally connected with the sealing ring.

[0013] The second annular piece, in the shape of a ring, is located on the inner edge of the sealing ring and is integrally connected to it. Both the first and second annular pieces are perpendicular to the sealing ring. The sealing ring, the first annular piece, and the second annular piece form a concave portion.

[0014] The extrusion strip is set inside the sealing ring, embedded in the middle layer of the sealing ring, and fixedly connected to the sealing ring. It is used to transfer the force of the other flange to the sealing ring near the end face of one flange.

[0015] Using the above technical solution, under the force of another flange, the outer wall of the sealing ring deforms and comes into close contact with the other flange, filling the threaded part of the other flange, and transmitting the force to the extrusion strip. The extrusion strip simultaneously compresses the sealing ring, the first ring plate, and the second ring plate to deform, so that the entire concave part is completely engaged with the protruding part of the flange end face.

[0016] More preferably, the number of extrusion strips is multiple, and the multiple extrusion strips are arranged in a concentric ring inside the sealing ring.

[0017] Using the above technical solution, concentric ring-shaped extrusion strips are arranged in circles inside the sealing ring to achieve layer-by-layer sealing from the inner layer to the outer layer on the flange end face, preventing liquid from flowing from the inner wall of the flange to the outer edge layer by layer, thus achieving the purpose of layer-by-layer sealing.

[0018] More preferably, the thickness of the first ring sheet is greater than the thickness of the second ring sheet, and the height of the first ring sheet is less than the height of the second ring sheet.

[0019] By adopting the above technical solution, the body forms a concave sealing structure with a thicker outer layer and a thinner inner layer, and a higher outer bottom and inner top. The second ring can fit well with the sealing ring and the inner wall of the flange, preventing liquid on the inner wall from flowing into the gap between the first ring and the threaded part of the flange end face, thereby improving the sealing performance.

[0020] Further optimization involves using silicone for the sealing ring, the first ring, and the second ring.

[0021] Using the above technical solution, the silicone material is soft and corrosion-resistant. After deformation, it can not only form a good close contact with the flange, but also has a long service life.

[0022] Further optimization involves using hard rubber as the material for the extrusion strip.

[0023] By adopting the above technical solution, the force of the other flange can be effectively transferred to the sealing ring. The action and reaction forces cause large deformations on both sides of the sealing ring, which fills the threaded parts of the flanges on both sides and further improves the sealing performance.

[0024] Further optimization involves the second ring being thin-walled, with its inner wall fitting against the inner wall of the flange.

[0025] By adopting the above technical solution, a tight contact can be formed with the inner wall of the flange, and together with the first ring and the sealing ring, the protruding part of the flange end face is covered in the concave structure.

[0026] Further optimization involves each pair of adjacent extrusion strips abutting against each other.

[0027] Using the above technical solution, extrusion strips are formed from the inside out, and the force can be transmitted to the concave part together through the closely spaced extrusion strips.

[0028] Further optimization involves making the outer wall of the sealing ring semi-circularly corrugated.

[0029] By adopting the above technical solution, the force can be completely transferred to the outer wall of the extrusion strip, maximizing the transfer of external force to improve sealing performance.

[0030] Further optimization involves ensuring that the width of the sealing ring is greater than or equal to the width of the protruding portion on the flange end face.

[0031] By adopting the above technical solution, the sealing ring can completely fill the threaded part of the flange end face, thereby improving the sealing performance. Attached Figure Description

[0039] The following is in conjunction with the appendix Figures 1-6 This utility model will be described in further detail.

[0040] A sealing component for desalination pipeline connections, such as Figure 1 As shown, it includes a body 2. The concave part of the body 2 is fastened to the end face of a flange 1 of the desalination pipeline, and the outer wall is fastened to the end face of another flange 1. Its surface transmits the force of the other flange 1 to the concave part. The concave part fills the threaded part of the end face of the flange 1 through deformation, and is also used to fill the end face of the other flange 1 through the deformation of the outer wall.

[0041] When another flange 1 applies force to the body 2, the concave part of the body 2 fills the entire space of the threaded part, while the outer wall fills the threaded space on the other flange 1. By filling and sealing the connection with the flanges 1 on both sides, the concave part of the body 2 and the flange 1 fasten together to prevent liquid in the demineralized water pipeline from entering the gap between the end face of the body 2 and the flange 1. The inner wall adheres to the inner wall of the flange 1 to prevent liquid on the inner wall of the demineralized water pipeline from entering the body 2. The contact between the outer wall and the end face of the flange 1 can transfer the force to the concave part through deformation, causing it to deform and preventing liquid from seeping out between the two flanges 1. This achieves a comprehensive sealing method of sealing layer by layer from the inner wall of the flange 1 and the end face of the flange 1, preventing the end faces of the two flanges 1 from shifting or misaligning and improving the sealing performance.

[0042] Specifically, such as Figure 1 and Figure 2 As shown, the body 2 in this embodiment includes:

[0043] The sealing ring 21 is annular and is mounted on a flange 1, which is attached to the end face of the flange 1.

[0044] The first annular piece 22 is annular in shape and is disposed on the outer edge of the sealing ring 21, and is integrally connected with the sealing ring 21.

[0045] The second annular piece 23, in the shape of a ring, is disposed on the inner edge of the sealing ring 21 and is integrally connected to the sealing ring 21. Both the first annular piece 22 and the second annular piece 23 are perpendicular to the sealing ring 21. The sealing ring 21, the first annular piece 22, and the second annular piece 23 form a concave portion.

[0046] The extrusion strip 24 is disposed inside the sealing ring 21, embedded in the middle layer of the sealing ring 21, and fixedly connected to the sealing ring 21. It is used to transfer the force of the other flange 1 to the sealing ring 21 near the end face of the flange 1.

[0047] Under the force of the other flange 1, the outer wall of the sealing ring 21 deforms and comes into close contact with the other flange 1, filling the threaded part of the other flange 1, and transmitting the force to the extrusion strip 24. The extrusion strip 24 simultaneously compresses the sealing ring 21, the first ring 22, and the second ring 23 to deform, so that the entire concave part is completely engaged with the protruding part on the end face of the flange 1.

[0048] Specifically, such as Figure 2 , Figure 4 as well as Figure 6 As shown, in this embodiment, there are multiple extrusion strips 24, which are arranged in a concentric ring within the sealing ring 21. The concentric ring extrusion strips 24 are arranged in a ring within the sealing ring 21 to achieve layer-by-layer sealing from the inner layer to the outer layer on the end face of the flange 1, preventing liquid from flowing from the inner wall of the flange 1 to the outer edge layer by layer, thus achieving the purpose of layer-by-layer sealing.

[0049] Specifically, such as Figure 2 , Figure 4 as well as Figure 6 As shown, the thickness of the first ring 22 is greater than the thickness of the second ring 23, and the height of the first ring 22 is less than the height of the second ring 23. The body 2 forms a concave sealing structure with a thicker outer surface and a thinner inner surface, and a higher outer bottom and inner surface. The second ring 23 can fit well against the inner wall of the sealing ring 21 and the flange 1, preventing liquid on the inner wall from flowing into the gap between the first ring 22 and the threaded part of the flange 1 end face, thereby improving the sealing performance.

[0050] Specifically, such as Figure 1 and Figure 3 As shown, in this embodiment, the sealing ring 21, the first ring 22, and the second ring 23 are all made of silicone. Silicone is soft and corrosion-resistant. After deformation, it can not only form a good close contact with the flange 1, but also has the characteristics of long service life.

[0051] Specifically, such as Figure 4 and Figure 5As shown, in this embodiment, the extrusion strip 24 is made of hard rubber, which can effectively transfer the force of the other flange 1 to the sealing ring 21. Through the action and reaction forces, the sealing ring 21 undergoes large deformation on both sides to fill the threaded parts of the flanges 1 on both sides, thereby further improving the sealing performance.

[0052] Specifically, such as Figure 2 , Figure 4 as well as Figure 5 As shown, in this embodiment, the second ring 23 is thin-walled, and its inner wall is attached to the inner wall of the flange 1, forming a tight contact with the inner wall of the flange 1. Together with the first ring 22 and the sealing ring 21, it covers the protruding part of the end face of the flange 1 inside the concave structure.

[0053] Specifically, such as Figure 4 As shown, in this embodiment, every two adjacent extrusion strips 24 abut against each other, forming closely spaced extrusion strips 24 from the inside out. The force can be transmitted to the concave part together through the closely spaced extrusion strips 24.

[0054] Specifically, such as Figure 1 As shown, in this embodiment, the outer wall of the sealing ring 21 is semi-circular corrugated, which can completely transfer the force to the outer wall of the extrusion strip 24, maximizing the transfer of external force to improve sealing performance.

[0055] Specifically, such as Figure 1 , Figure 2 as well as Figure 3 As shown, in this embodiment, the width of the sealing ring 21 is greater than or equal to the width of the protruding part on the end face of the flange 1. The sealing ring 21 can completely fill the threaded part on the end face of the flange 1, thereby improving the sealing performance.

[0056] Specifically, such as Figure 1 As shown, a handle 3 is provided on the main body 2. The handle 3 is fixedly connected to the first ring piece 22. The handle 3 is parallel to the end face of the flange 1. The end of the handle 3 extends out of the outside of the flange 1 for hand gripping, so as to assist the hand in rotating and adjusting the position of the main body 2 on the flange 1 and the degree of fastening with the flange 1.

[0057] Please combine Figures 1-6 The installation and sealing process in this embodiment is described as follows:

[0058] Separate the two disconnected desalination water pipelines and align them with the flanges 1 to which they are connected. Hold the handle 3 and fasten the concave part of the body 2 onto the protruding part of one side of the flange 1 to prevent misalignment or displacement due to improper installation. At the same time, the second ring 23 should fit tightly against the inner wall of the flange 1, and the first ring 22 should fit against the outer wall of the protruding part to achieve a seal from the inner wall of the flange 1. If the handle 3 obstructs the bolt holes on the flange 1, it can be rotated to adjust it between two adjacent bolt holes for easy bolt installation. During the tightening of the bolts, the protruding part of the flange 1 on the other side applies a force to the sealing ring 21. The outer wall of the sealing ring 21 transmits the force to the extrusion strip 24. Under the action of the force, the extrusion strip 24 extrudes the sealing ring 21. After being extruded, the sealing ring 21 deforms and fills the threaded part of one flange 1, sealing the connection with the protruding part. At the same time, the outer wall of the sealing ring 21 is also deformed by the reaction force of the extrusion strip 24, filling the threaded part of the end face of the other flange 1. The extrusion strip 24 simultaneously squeezes the sealing ring 21 into the end faces of both flanges 1, achieving a sealing connection with both flanges 1 and preventing the liquid in the demineralized water pipe from seeping into the space between the body 2 and the flange 1.

[0059] In summary, the sealing ring 21, the first ring 22, and the second ring 23, together with the flange 1, provide comprehensive sealing from its inner wall and threaded parts, preventing leakage at the desalination pipeline connection and thus avoiding waste, environmental pollution, and improving sealing performance.

[0060] This specific embodiment is merely an explanation of the utility model and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection of this utility model.
