Description

Technical Field

[0001] This utility model relates to the field of drainage construction technology, and in particular to a sealing connection clamp assembly for water supply and drainage pipelines. Background Technology

[0002] A pipe sealing clamp assembly is a mechanical device used for quickly connecting and sealing water supply and drainage pipes, typically made of metal or high-strength plastic. It clamps the ends of two pipe sections together using fastening bolts or a snap-fit ​​structure, combined with an elastic sealing ring (such as a rubber gasket) to achieve a leak-proof connection.

[0003] In water supply and drainage engineering, clamp components are widely used due to their quick assembly and disassembly advantages. However, existing technologies still have obvious drawbacks: under pressure fluctuations or temperature deformation conditions, uneven pressure on rubber sealing rings or aging can easily lead to leakage at the joints. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a sealing connection clamp assembly for water supply and drainage pipes, which can achieve long-term sealing.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A sealing connection clamp assembly for water supply and drainage pipes, comprising: a water pipe assembly, a sealing ring, and a clamp structure;

[0007] The water pipe assembly includes at least two water pipe segments. The outer wall of the end of each water pipe segment is provided with a first annular flange, which extends circumferentially around the water pipe segment. The two water pipe segments are connected end to end, and a gap to be sealed is formed at the connection of the two water pipe segments. A receiving groove is formed between two first annular flanges belonging to different water pipe segments.

[0008] The sealing ring is nested around the receiving groove; the thickness of the sealing ring is greater than the depth of the receiving groove, so that the protrusion of the sealing ring protrudes from the inside to the outside of the receiving groove along the radial direction of the sealing ring;

[0009] The clamp structure is sleeved around the sealing ring and the first annular flange. The two ends of the clamp structure abut against one of the first annular flanges, and the two first annular flanges are located between the two ends of the clamp structure. The clamp structure is spaced apart from the periphery of the first annular flange to form a secondary sealing cavity. The clamp structure squeezes the protrusion so that the protrusion is embedded in the secondary sealing cavity.

[0010] Furthermore, the water pipe segment is also provided with a second annular flange, which extends circumferentially around the water pipe segment; the two ends of the clamp structure respectively abut against one of the second annular flanges, and the clamp structure is located between the two second annular flanges.

[0011] Furthermore, the axial thickness of the first annular flange is less than the axial thickness of the second annular flange.

[0012] Furthermore, the clamp structure is provided with an annular groove, which extends circumferentially along the clamp structure, and the protrusion of the sealing ring is embedded in the annular groove.

[0013] Furthermore, the water pipe segment is a one-piece molded structure.

[0014] Furthermore, the water pipe segment is made of plastic.

[0015] Furthermore, the clamp structure includes at least a plurality of ring blocks, which are detachably connected end to end around the clamp structure.

[0016] Furthermore, adjacent two of the ring blocks are connected by a locking member.

[0017] Furthermore, each of the two adjacent ring blocks is provided with a socket, and the two sockets are coaxially distributed. The locking member is a locking rod, and the plug end of the locking rod passes through the two coaxially distributed sockets. The plug end is connected to an elastic protrusion, and the elastic protrusion protrudes from the inside to the outside of the outer wall of the locking rod along the radial direction of the locking rod.

[0018] Furthermore, the insertion end has an internal cavity, and the elastic protrusion includes a first protrusion block, a second protrusion block, and a spring. The first protrusion block, the second protrusion block, and the spring are housed in the internal cavity. The first protrusion block and the second protrusion block respectively abut against the two ends of the spring and protrude from the inside to the outside of the outer wall of the locking rod along the axial direction of the locking rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. The receiving groove is used to receive the sealing ring, creating conditions for the gap to be sealed. By changing the distance between the first annular flange and the end of the water pipe segment, the width of the receiving groove can be controlled. When there is a sealing ring in the receiving groove, the first annular flange and the sealing ring are fully fitted together, and the first annular flange plays the role of positioning and fastening the sealing ring.

[0021] 2. The thickness of the sealing ring is greater than the depth of the receiving groove, so that the sealing ring has a protrusion relative to the first annular flange. This protrusion can cooperate and contact with a third-party device, which is the basis for subsequent secondary sealing.

[0022] 3. When the two ends of the clamp structure abut against one of the first annular flanges, the axial sliding force of the water pipe segment will be offset by the supporting force of the clamp structure on the first annular flange. In other words, the clamp structure plays a role in axially fixing the water pipe assembly.

[0023] 4. Because the thickness of the sealing ring is greater than the depth of the receiving groove, the sealing ring has a protrusion relative to the first annular flange. Therefore, the inner wall of the clamping structure abuts against the protrusion of the sealing ring instead of the first annular flange. Furthermore, because the clamping structure abuts against the first annular flange, a secondary sealing cavity can be formed between the clamping structure, the protrusion of the sealing ring, and the first annular flange. Since the sealing ring is made of rubber, which has a lower hardness than the clamping structure, the clamping structure can compress the protrusion of the sealing ring. The protrusion deforms under pressure and embeds itself into the secondary sealing cavity, thereby achieving a secondary seal. Attached Figure Description

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0035] It should be noted that when an element is described as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is described as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] like Figures 1 to 7 As shown, the water supply and drainage pipe sealing connection clamp assembly of this utility model embodiment includes: a water pipe assembly 1, a sealing ring 2, and a clamp structure 3.

[0038] The water pipe assembly 1 includes at least two water pipe segments 11; the outer wall of the end of each water pipe segment 11 is provided with a first annular flange 12, which extends circumferentially around the water pipe segment 11; the two water pipe segments 11 are connected end to end, and a gap 4 to be sealed is formed at the connection of the two water pipe segments 11; a receiving groove 5 is formed between the two first annular flanges 12 belonging to different water pipe segments 11; it can be understood that the receiving groove 5 is used to accommodate the sealing ring 2, creating conditions for the gap 4 to be sealed. By changing the distance between the first annular flange 12 and the end of the water pipe segment 11, the width of the receiving groove 5 can be controlled. When the receiving groove 5 contains the sealing ring 2, the first annular flange 12 and the sealing ring 2 are fully fitted, and the first annular flange 12 plays the role of positioning and fastening the sealing ring 2.

[0039] The sealing ring 2 is nested around the receiving groove 5. It can be understood that the sealing ring 2 provides axial fixation for the water pipe assembly 1. At this point, the water pipe segments 11 connected end-to-end are initially sealed by the sealing ring 2, but there is still a possibility of radial slippage along the water pipe segments 11. The thickness of the sealing ring 2 is greater than the depth of the receiving groove 5, so that the protrusion 21 of the sealing ring 2 protrudes radially from the inside to the outside of the receiving groove 5. It should be noted that the sealing ring 2 is made of rubber material and has a certain degree of extensibility. It can be understood that the thickness of the sealing ring 2 being greater than the depth of the receiving groove 5 results in the sealing ring 2 having a protrusion 21 relative to the first annular flange 12. This protrusion 21 can cooperate with a third-party device, forming the basis for subsequent secondary sealing.

[0040] The clamp structure 3 is sleeved around the sealing ring 2 and the first annular flange 12. Each end of the clamp structure 3 abuts against one of the first annular flanges 12, and the two first annular flanges 12 are located between the two ends of the clamp structure 3. It should be noted that it is necessary for each end of the clamp structure 3 to abut against one of the first annular flanges 12. If they do not abut, the clamp structure 3 will be able to slide radially back and forth along the water pipe segment 11, failing to provide a sealing and fixing function. In other words, the first annular flange 12 can position the clamp structure 3 at this time. It can be understood that when each end of the clamp structure 3 abuts against one of the first annular flanges 12, the axial sliding force of the water pipe segment 11 is offset by the supporting force of the clamp structure 3 on the first annular flange 12. In other words, the clamp structure 3 provides axial fixation for the water pipe assembly 1.

[0041] The clamping structure 3 is spaced apart from the periphery of the first annular flange 12 to form a secondary sealing cavity 6. The clamping structure 3 compresses the protrusion 21, causing the protrusion 21 to embed into the secondary sealing cavity 6. It can be understood that because the thickness of the sealing ring 2 is greater than the depth of the receiving groove 5, the sealing ring 2 has a protrusion 21 relative to the first annular flange 12. Therefore, the inner wall of the clamping structure 3 abuts against the protrusion 21 of the sealing ring 2 instead of against the first annular flange 12. Furthermore, because the clamping structure 3 abuts against the first annular flange 12, a secondary sealing cavity 6 can be formed between the clamping structure 3, the protrusion 21 of the sealing ring 2, and the first annular flange 12. Since the sealing ring 2 is made of rubber, its hardness is lower than that of the clamping structure 3. Therefore, the clamping structure 3 can compress the protrusion 21 of the sealing ring 2. The protrusion 21 is deformed by the compression and embedded into the secondary sealing cavity 6, thereby achieving a secondary seal.

[0042] like Figure 3 As shown, in this embodiment, preferably, the water pipe segment 11 is further provided with a second annular flange 13, which extends circumferentially around the water pipe segment 11; the two ends of the clamp structure 3 respectively abut against one of the second annular flanges 13, and the clamp structure 3 is located between the two second annular flanges 13. It can be understood that the second annular flange 13 can limit the clamp structure 3, and the combination of the second annular flange 13 and the first annular flange 12 can position the clamp structure 3. Furthermore, since the clamp structure 3 is generally a non-transparent structure, the edge of the second annular flange 13 can be used to determine whether the clamp structure 3 is installed accurately.

[0043] In this embodiment, preferably, the axial thickness of the first annular flange 12 is less than the axial thickness of the second annular flange 13. It can be understood that the supporting force of the second annular flange 13 on the clamping structure 3 needs to be greater than the pressure of the first annular flange 12 on the clamping structure 3, thereby preventing the clamping structure 3 from deforming due to stress impact during operation.

[0044] In this embodiment, preferably, the clamping structure 3 is provided with an annular groove 31, which extends circumferentially along the clamping structure 3, and the protrusion 21 of the sealing ring 2 is embedded in the annular groove 31. It can be understood that compared to the sealing ring 2 directly contacting the inner wall of the clamping structure 3, the protrusion 21 of the sealing ring 2 being embedded in the annular groove 31 allows for a tighter fit between the sealing ring 2 and the clamping structure 3, effectively reducing minor slippage and improving the secondary sealing effect.

[0045] like Figure 5As shown, in this embodiment, preferably, the water pipe segment 11 is a one-piece molded structure. It can be understood that in the field of drainage construction technology, the one-piece molding process of the water pipe segment 11 can significantly improve its overall performance and service life. Due to the absence of welding points, the pipe's sealing and anti-leakage capabilities are greatly enhanced, making it particularly suitable for transporting high-pressure or corrosive fluids. On the one hand, the one-piece molded structure eliminates stress concentration at the interface, resulting in more uniform stress distribution on the pipe body, superior pressure and seismic resistance, and reduced susceptibility to cracking or deformation over long-term use; on the other hand, the smooth inner wall reduces fluid resistance, lowers energy consumption, and prevents impurity deposition.

[0046] In this embodiment, preferably, the water pipe segment 11 is made of plastic. It is understood that the water supply and drainage pipe segment 11 made of plastic has the characteristics of being lightweight, high-strength, corrosion-resistant, and having excellent hydraulic performance. Plastic pipes are lightweight, convenient to transport and install, and can significantly reduce construction costs. Their excellent chemical corrosion resistance allows them to withstand acids, alkalis, salts, and various corrosive media for a long time, resulting in a long service life. The smooth inner wall of the plastic pipe results in a low coefficient of friction and low water flow resistance. Plastic pipes also have good flexibility, allowing them to adapt to external forces such as foundation settlement and earthquakes without easily breaking. Furthermore, plastic pipes are non-toxic and odorless, meet drinking water hygiene standards, and have good thermal insulation properties, effectively preventing freezing and cracking in winter.

[0047] like Figure 7 As shown, in this embodiment, preferably, the clamping structure 3 includes at least a plurality of ring blocks 32, which are detachably connected end-to-end around the clamping structure 3. It should be noted that there are at least two ring blocks 32. If there are three or more ring blocks 32, except for the first and last two ring blocks 32, the remaining ring blocks 32 can be pre-connected by means of hinges or other methods to facilitate installation. Compared to a clamping structure 3 with two ring blocks 32, a clamping structure 3 with three or more ring blocks 32 has more closed joints. On the one hand, multi-point compression enhances the fit of the sealing surface, making it particularly adaptable to irregular or highly elliptical pipes. On the other hand, it further disperses radial pressure, reduces local stress concentration, and reduces the risk of seal failure or pipe deformation caused by uneven stress.

[0048] like Figure 1 As shown, in this embodiment, preferably, two adjacent annular blocks 32 are connected by a locking member 7. It can be understood that the locking member 7 can be a single component or a combination of multiple components. After the two adjacent annular blocks 32 are connected by the locking member 7, the sealing connection clamp assembly for water supply and drainage pipes of this utility model is installed.

[0049] like Figure 8As shown, in this embodiment, preferably, each of the two adjacent annular blocks 32 has an insertion hole 8, and the two insertion holes 8 are coaxially distributed. The locking member 7 is a locking rod 9, and the insertion end 91 of the locking rod 9 passes through the two coaxially distributed insertion holes 8. The insertion end 91 is connected to an elastic protrusion 10, and the elastic protrusion 10 protrudes from the inside to the outside of the outer wall of the locking rod 9 along the radial direction of the locking rod 9. It should be noted that the locking rod 9 also includes a gripping end 92, the diameter of which is larger than the diameter of the insertion end 91. On the one hand, this increases the contact area for easy gripping, and on the other hand, it prevents the locking rod 9 from sliding away from the gripping end 92.

[0050] like Figure 9 As shown, in this embodiment, preferably, the insertion end 91 has an internal cavity 93, and the elastic protrusion 10 includes a first protrusion block 101, a second protrusion block 102 and a spring 103. The first protrusion block 101, the second protrusion block 102 and the spring 103 are accommodated in the internal cavity 93. The first protrusion block 101 and the second protrusion block 102 respectively abut against the two ends of the spring 103 and protrude from the inside to the outside of the outer wall of the locking rod 9 along the radial direction of the locking rod 9. It is understandable that when the plug end 91 is inserted into the socket 8, the plug end 91 is subjected to pressure from the inner wall of the socket 8. The first protrusion block 101 and the second protrusion block 102 of the elastic protrusion 10 are completely squeezed into the internal cavity 93, allowing the plug end 91 to smoothly pass through the socket 8. Once the end of the plug end 91 has passed through the socket 8, the elastic protrusion 10 is no longer subjected to pressure from the inner wall of the socket 8. The spring 103 rebounds, causing the first protrusion block 101 and the second protrusion block 102 to protrude again from the inside to the outside of the locking rod 9. At this time, the first protrusion block 101 and the second protrusion block 102 abut against the retaining block 32, preventing the locking rod 9 from moving along the direction from the plug end 91 to the gripping end 92, thus achieving locking. Compared with the traditional bolt connection, this locking method does not require additional tools, improving the speed of installation and disassembly.
