Description

Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to a high-performance pipeline connecting flange. Background Art

[0002] A flange is a ring-shaped part used to connect pipes, valves, pumps and other equipment or components. It is usually equipped with bolt holes, and fasteners such as bolts and nuts are used to achieve a tight connection between components. The existence of flanges enables complex mechanical systems to operate stably and efficiently. Flanges are widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industries, refrigeration, sanitation, pipelines, fire protection, electricity, aerospace, and shipbuilding.

[0003] However, the flange also has the following defects during use:

[0004] 1. During the use of flanges, since flanges are used to connect two pipes, during the process of conveying liquids through the pipelines, the flanges will be subjected to the impact force generated when the liquid is conveyed from one pipeline to another, which will cause the bolts for installing the flanges to loosen, and then cause leakage when the pipeline is conveying liquid, thereby causing a waste of liquid resources.

[0005] 2. Due to the loosening of the bolts between the mounting flanges, when liquid leakage occurs at the pipe connection, it is difficult for the user to discover it in time, and it is impossible to stop the liquid delivery and repair the pipe connection in time, thereby reducing the liquid delivery volume. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the utility model provides a high-performance pipeline connecting flange, which can effectively solve the problems in the prior art.

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] The utility model discloses a high-performance pipeline connecting flange, comprising a first flange and a second flange, wherein the first flange and the second flange are mounted together by bolts and nuts, and a waterproof warning component is provided between the first flange and the second flange;

[0009] The waterproof warning component is used to buffer the flow of liquid inside the pipeline and drain the liquid leaking from the gap between the first flange and the second flange. The waterproof warning component can also issue an early warning after the liquid is drained.

[0010] Furthermore, the waterproof warning assembly includes a drainage ring, which is fixedly connected to the inside of the first flange, and is inserted into the side of the second flange close to the first flange. An expansion groove is opened inside the drainage ring.

[0011] Furthermore, a waterproof ring is fixedly connected to one side of the second flange close to the first flange, and the waterproof ring can be inserted into the drainage ring. The outer surface of the waterproof ring is fixedly connected to a hydrogel ring, and the hydrogel ring is arranged inside the expansion tank.

[0012] Furthermore, a buffer ring is fixedly connected to the interior of the waterproof ring, and the center of the buffer ring is on the same horizontal line as the centers of the first flange and the second flange.

[0013] Furthermore, a drainage tube is fixedly connected to the outer surface of the drainage ring, and the drainage tube is inserted into the inside of the first flange and the second flange. The end of the drainage tube close to the drainage ring is connected to the expansion groove, and the side of the first flange close to the second flange is fixedly connected to a warning box, and the side of the second flange close to the first flange is provided with an installation groove, and the end of the drainage tube away from the drainage ring is located directly above the warning box.

[0014] Furthermore, a spring is symmetrically fixedly connected to the inside of the warning box, the top of the spring is fixedly connected to a pressure plate, and a warning switch is fixedly connected to the inside of the warning box, and the warning switch is located directly below the pressure plate.

[0015] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0016] 1. The utility model adopts the method of plugging the drainage ring and the waterproof ring to promote the tightness between the first flange and the second flange by means of the liquid flow force when the liquid is transported from the first flange to the inside of the second flange. When liquid leaks, the liquid contacts the buffer ring, which can make the hydrogel ring expand by utilizing its own characteristic of swelling when encountering liquid. After expansion, the hydrogel ring can fill the expansion groove to prevent the liquid from leaking into the drainage tube, thereby timely blocking the leakage between the first flange and the second flange, reducing the flow of liquid leaking into the expansion groove, thereby ensuring the liquid transportation amount between the first flange and the second flange, and helping to improve the sealing between the first flange and the second flange.

[0017] 2. When the liquid leakage is serious, the leaked liquid can be drained into the interior of the warning box through the drainage tube. When the liquid continues to increase, the warning box moves downward by the gravity of the liquid, pressing the warning switch, so that the warning light installed in the monitoring room sounds, thereby alerting the user and facilitating the user to repair the leakage between the first flange and the second flange in time, thereby ensuring the smooth operation of the pipeline and the first flange and the second flange.

[0018] 3. By installing a buffer ring inside the waterproof ring, the impact force of the liquid on the flange can be reduced when the liquid passes through, thereby reducing the vibration force generated by the flange when the liquid flows, and then preventing the bolts on the flange from loosening, which is beneficial to improving the stability of the flange-connected pipe.

[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] A high performance pipe connection flange of this embodiment, such as Figures 1 to 6 As shown, it includes a first flange 1 and a second flange 2, and the first flange 1 and the second flange 2 are mounted together by bolts 3 and nuts 4;

[0032] In view of the above-mentioned first flange 1 and second flange 2, the specific implementation can be as follows:

[0033] A waterproof warning component is provided between the first flange 1 and the second flange 2. The waterproof warning component is used to buffer the flow of liquid inside the pipeline and drain the liquid leaking from the gap between the first flange 1 and the second flange 2. The waterproof warning component can also issue an early warning after the liquid is drained.

[0034] As a preferred implementation in this embodiment, Figure 3 and Figure 4 As shown, the waterproof warning assembly includes a drainage ring 51, which is fixedly connected to the interior of the first flange 1 and inserted into the side of the second flange 2 near the first flange 1. An expansion groove is defined inside the drainage ring 51. A waterproof ring 52 is fixedly connected to the side of the second flange 2 near the first flange 1 and can be inserted into the interior of the drainage ring 51. A hydrogel ring 54 is fixedly connected to the outer surface of the waterproof ring 52. The hydrogel ring 54 is disposed within the expansion groove. A buffer ring 53 is fixedly connected to the interior of the waterproof ring 52. The center of the buffer ring 53 is aligned with the center of the first flange 1 and the second flange 2. When liquid leaks, the contact between the liquid and the buffer ring 53 causes the hydrogel ring 54 to expand due to its inherent ability to expand in contact with liquid. After expansion, the hydrogel ring 54 fills the expansion groove, preventing liquid from leaking into the drainage tube 55.

[0035] As a preferred implementation in this embodiment, Figure 4 、 Figure 5 and Figure 6As shown, a drainage tube 55 is fixedly connected to the outer surface of the drainage ring 51. The drainage tube 55 is inserted into the first flange 1 and the second flange 2. The end of the drainage tube 55 near the drainage ring 51 is connected to the expansion tank. A warning box 56 is fixedly connected to the side of the first flange 1 near the second flange 2. A mounting slot is defined on the side of the second flange 2 near the first flange 1. The end of the drainage tube 55 away from the drainage ring 51 is located directly above the warning box 56. A spring 58 is symmetrically fixedly connected to the interior of the warning box 56. The top of the spring 58 is fixedly connected to the pressure plate 57. A warning switch 59 is fixedly connected to the interior of the warning box 56 and is located directly below the pressure plate 57. The warning box 56 moves downward due to the gravity of the liquid, pressing the warning switch 59, causing the warning light installed in the monitoring room to sound, thereby alerting the user.

[0036] Compared with the prior art, during use, when liquid leaks between the first flange 1 and the second flange 2, the present invention can promptly block the leakage through the expansion of the hydrogel ring 54, reduce the amount of liquid leakage, and drain the leaked liquid into the warning box 56 through the drainage tube 55, and use the gravity of the liquid volume to activate the early warning, so that the user can repair the leakage in time, thereby improving the sealing of the first flange 1 and the second flange 2 during use and ensuring that the first flange 1 and the second flange 2 can operate smoothly.

[0037] Working principle:

[0038] Initial limit:

[0039] Before installing this utility, the user needs to install a warning light in the monitoring room and electrically connect the warning light to the warning switch 59. By turning the bolts 3 and nuts 4, the first flange 1 and the second flange 2 are installed on the two pipes, thereby completing the connection between the pipes and the first flange 1 and the second flange 2.

[0040] Liquid leakage and blockage steps:

[0041] When liquid leaks from the connection between the first flange 1 and the second flange 2, Figure 4 As shown, liquid leaks from the connection between the first flange 1 and the second flange 2 into the expansion groove inside the drainage ring 51. After the hydrogel ring 54 installed on the outer surface of the waterproof ring 52 comes into contact with the liquid inside the expansion groove, it will use its own characteristic of expanding when encountering liquid to fill the entire expansion groove, thereby blocking the leakage between the first flange 1 and the second flange 2 and reducing the amount of liquid leakage.

[0042] When the liquid leak is serious, such as Figure 4 、 Figure 5 and Figure 6As shown, the liquid flows from the expansion groove of the drainage ring 51 to the drainage tube 55, and then flows from the drainage tube 55 to the warning box 56. After entering the warning box 56, the liquid flows to the top of the pressure plate 57. Since the pressure plate 57 is installed inside the warning box 56 by the spring 58, the pressure plate 57 moves downward under the action of the liquid gravity. During the downward movement, the pressure plate 57 presses the warning switch 59, thereby triggering the warning light switch, issuing an early warning to the user, reminding the user that there is a fault between the first flange 1 and the second flange 2, so that the user can block it in time.

[0043] like Figure 3 As shown, by installing the buffer ring 53 inside the drainage ring 51, and the center of the buffer ring 53 is on the same horizontal line as the center of the first flange 1 and the second flange 2, the impact force of the liquid on the flange can be reduced when the liquid passes through, thereby reducing the vibration force generated by the flange when the liquid flows, and then preventing the bolts 3 on the flange from loosening, which is beneficial to improving the stability of the flange-connected pipeline.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
