Description

Technical Field

[0001] This utility model belongs to the field of water supply network maintenance, specifically a segmented flange sealing clamp for water supply networks. Background Technology

[0002] Water supply networks are systems that deliver compliant domestic and industrial water to users. They require regular maintenance, with flange connections being a key maintenance target. Leaks at these connections need to be plugged promptly, which requires specialized leak-sealing clamps. These devices can quickly seal leaks at flange connections.

[0003] Meanwhile, a convenient temporary flange sealing clamp with application number CN202220278935.6 includes two clamping sleeves, each with a semi-circular arc structure. The inner wall of each clamping sleeve has an installation groove extending along its length, and a sealing strip is installed within the groove. This sealing clamp, by using two clamping sleeves and a sealing strip within them, enables the clamping sleeves to hold the flange while the sealing strip quickly seals the leaking gap between the two flanges, thus achieving rapid and convenient flange sealing. Simultaneously, by using multiple clamping blocks, the clamping clamps bring the two flanges closer together, further tightening and sealing them.

[0004] However, the following problems were found in the implementation of the relevant technology: Although the existing equipment can quickly plug the leaks in the flange, it is necessary to inject glue during the plugging process, which makes the operation inconvenient. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a segmented flange sealing clamp for water supply networks, which has the advantages of sealing leaks without the need for glue injection when there is only a single or small leak on the flange, and is more convenient to operate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a segmented flange sealing clamp for a water supply network, comprising a first clamp and a second clamp supported at the bottom of the first clamp. Connecting members are integrally formed at the left and right ends of both the first and second clamps, and connecting holes are provided at the top of the connecting members. Connecting bolts are screwed between corresponding connecting holes, and nuts are screwed to the tails of the connecting bolts, with the nuts abutting against the bottom of the corresponding connecting members. A connecting block is integrally formed at the bottom of the second clamp, and a screw rod is screwed to the middle of the connecting block. The top of the screw rod penetrates the bottom of the second clamp and is fitted with an arc-shaped sealing plate via a bearing. A limiting rod is connected to the bottom right side of the sealing plate, and the limiting rod is movably inserted into the corresponding sides of the second clamp and the connecting block. Baffles are integrally formed on the front and rear inner walls of the first clamp and the front and rear inner walls of the second clamp.

[0007] Preferably, a rubber sheet is adhered to the top of the sealing plate, and the rubber sheet is flush with the edge of the sealing plate.

[0008] Preferably, the inner bottom of the second jacket is provided with a groove, and the leak-stopping plate is located inside the groove.

[0009] Preferably, a rotating rod is fixedly inserted into the lower part of the screw, and circular limiting members are connected to both the left and right ends of the rotating rod.

[0010] Preferably, the first jacket and the connector and the baffle, the second jacket and the connector and the baffle, and the second jacket and the connecting block are all die-cast integral structures.

[0011] Preferably, an injection joint is inserted into the top of the first jacket, and the injection joint communicates with the inner side of the first jacket.

[0012] Preferably, the bottom of the first jacket is integrally formed by symmetrical die casting with two positioning posts, and the top of the second jacket is constructed with positioning holes for inserting the positioning posts.

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

[0014] 1. This utility model uses a first jacket and a second jacket to clamp the outer side of the flange, and then tightens the screw to make the sealing plate fit tightly to the leak, thus completing the leak sealing. When there is only a single or small leak on the flange, the leak can be directly sealed by the sealing plate without the need for glue injection, making the overall operation more convenient.

[0015] 2. This utility model uses two positioning pins and positioning holes to quickly align the first and second clamping sleeves, and then fixes them with connecting bolts and nuts, which makes it easier to fix the first and second clamping sleeves. Attached Figure Description

[0020] 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.

[0021] like Figures 1 to 3 As shown, this utility model provides a segmented flange sealing clamp for a water supply network, including a first clamp 1 and a second clamp 2 supported at the bottom of the first clamp 1. Connecting parts 3 are integrally formed at the left and right ends of both the first clamp 1 and the second clamp 2. Connecting holes are provided at the top of the connecting parts 3, and connecting bolts 4 are screwed between the corresponding connecting holes. Nuts 5 are screwed to the tail of the connecting bolts 4. The connecting bolts 4 and nuts 5 can fix the two sets of connecting parts 3, thereby fixing the first clamp 1 and the second clamp 2. The nuts 5 abut against the bottom of the corresponding connecting parts 3. A connecting block 6 is integrally formed at the bottom of the second clamp 2, and a screw rod 7 is screwed to the middle of the connecting block 6. The screw rod 7 can be connected relative to the connecting block 6 and the first clamp 2. The second jacket 2 is screwed, and the top of the screw 7 passes through the bottom of the second jacket 2 and is fitted with an arc-shaped leak-stopping plate 8 through a bearing. Tightening the screw 7 can control the leak-stopping plate 8 to move upward so that it is close to the leaking part of the flange. The bottom right side of the leak-stopping plate 8 is threaded with a limiting rod 9. The threaded connection makes it easy to disassemble and maintain. The limiting rod 9 is movably inserted into the corresponding side of the second jacket 2 and the connecting block 6. The limiting rod 9 ensures that the leak-stopping plate 8 can move upward smoothly and will not tilt with the rotation of the screw 7. The front and rear inner walls of the first jacket 1 and the front and rear inner walls of the second jacket 2 are integrally formed with baffles 12. After the equipment is installed, the front and rear baffles 12 will be fitted on both sides of the flange to help prevent water leakage.

[0022] Specifically, a rubber cloth 11 is bonded to the top of the leak-stopping plate 8, and the rubber cloth 11 is flush with the edge of the leak-stopping plate 8, which improves the effect of the leak-stopping plate 8 in sealing the leak and can fill the gaps when sealing the leak.

[0023] Furthermore, the inner bottom of the second jacket 2 is provided with a groove 13, and the leak-stopping plate 8 is located inside the groove 13 to prevent the leak-stopping plate 8 from affecting the fixation of the second jacket 2 and the first jacket 1.

[0024] Furthermore, a rotating rod 10 is fixedly inserted into the lower part of the screw 7, which facilitates the application of force to tighten the screw 7. Both the left and right ends of the rotating rod 10 are connected to circular limiting parts to prevent the rotating rod 10 from accidentally slipping out of hand during the tightening process.

[0025] It is worth noting that the first jacket 1 and the connecting piece 3 and the baffle 12, the second jacket 2 and the connecting piece 3 and the baffle 12, and the second jacket 2 and the connecting block 6 are all die-cast integral structures. The die-cast integral structure has high strength, is not easily damaged, and is durable.

[0026] It is worth noting that the top of the first jacket 1 is connected to an injection joint 15, and the injection joint 15 is connected to the inside of the first jacket 1. When the leakage is large or there are multiple leaks, the injection joint 15 can be used to inject glue, which can be used in conjunction with the sealing plate 8 to seal the leak.

[0027] It is worth mentioning that the bottom of the first jacket 1 is symmetrically die-cast and integrally formed with two positioning posts, and the top of the second jacket 2 is constructed with positioning holes 14 for inserting positioning posts. This set of structures facilitates the alignment of the first jacket 1 and the second jacket 2, which can improve the convenience of their installation.

[0028] The front, back, left, and right perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0029] Working principle: Align the groove 13 of the second jacket 2 with the leaking part of the flange and place it close to the flange. Then align the first jacket 1 with the second jacket 2 and fix them with two sets of connecting bolts 4 and nuts 5. Then, continuously turn the screw 7 by rotating the rod 10 until it can no longer be turned. The leak-stopping plate 8 at the top of the screw 7 will then be close to the leaking part to complete the leak-stopping. When the leaking part of the flange is small or there is only a single leaking part, there is no need to perform glue injection. The overall operation is more convenient.
