Description

Technical Field

[0001] This utility model relates to the field of irregular flanges, and in particular to irregular flanges with excellent sealing performance. Background Technology

[0002] Irregular flange bodies refer to flanges with irregular shapes and sizes that differ from standard flanges. Compared to traditional round or standard-shaped flanges, irregular flange bodies are usually designed according to specific needs or application scenarios, and have special geometric shapes that may be non-circular, non-standard sizes, or other complex forms.

[0003] When two irregular flange bodies are used to connect a pipeline, the seal between the two irregular flange bodies is usually achieved by an elastic sealing ring block installed on one side of the irregular flange body. The sealing ring block is mostly made of materials such as rubber or asbestos rubber. The pre-tightening force generated by the bolt tightening causes the sealing ring block to elastically deform and fit tightly against one side of the two irregular flange bodies, thereby blocking the flow of media. However, during long-term use, the sealing ring block will gradually experience elastic decay, shrinkage and hardening due to factors such as media corrosion, temperature changes, pressure fluctuations and the aging of its own materials. When the sealing ring block ages and shrinks, the tightness of the fit between one side of the two irregular flange bodies will decrease, resulting in weakened sealing performance and even leakage, and a limited service life. Utility Model Content

[0004] The technical problem this utility model aims to solve is as follows: When two irregular flange bodies are used to connect a pipeline, the seal between the two irregular flange bodies is usually achieved by an elastic sealing ring block installed on one side of the irregular flange body. The sealing ring block is mostly made of materials such as rubber and asbestos rubber. The pre-tightening force generated by bolt tightening causes the sealing ring block to elastically deform and tightly fit against one side of the two irregular flange bodies, thereby blocking the flow of media. However, during long-term use, the sealing ring block will gradually experience elastic decay, shrinkage and hardening due to factors such as media corrosion, temperature changes, pressure fluctuations and aging of its own materials. When the sealing ring block ages and shrinks, the tightness of the fit between one side of the two irregular flange bodies will decrease, resulting in weakened sealing performance and even leakage, and a limited service life.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a non-circular flange with excellent sealing performance, including a non-circular flange body, a sealing device is provided on one side of the non-circular flange body, the sealing device uses bolts to drive the abutment frame to move and squeeze and push the abutment block, thereby driving the slider and sealing ring block to slide out from the circular groove, and adjusting the height of the sealing ring block protruding on one side of the non-circular flange body to achieve the effect of tightly fitting the gap between the two non-circular flange bodies and improving the sealing performance.

[0006] Preferably, the sealing device includes a slider, a circular groove is formed on one side of the irregular flange body, and a sliding groove is formed on the inner wall of the circular groove, wherein the outer surface of the slider is slidably installed in the inner wall of the circular groove; a sealing ring block, wherein one side of the sealing ring block is fixedly installed on one side of the slider and inserted into the inner wall of the circular groove; a plurality of springs, wherein the two ends of the springs are respectively fixedly installed on one side of the slider and one side of the inner wall of the circular groove; two abutment blocks, wherein one side of the abutment block is fixedly installed on the side of the slider away from the sealing ring block; an abutment frame, wherein the abutment frame is slidably installed in the inner wall of the sliding groove, and its two ends abut against one side of the two abutment blocks respectively; and a threaded rod, wherein one end of the threaded rod is installed through one side of the inner wall of the sliding groove, and its outer surface is threadedly connected to the inner wall of the abutment frame.

[0007] The effect achieved by the above-mentioned components is as follows: By setting up a sealing device, when the main body of the irregular flange is installed on the pipeline, and then the main bodies of the two irregular flanges on the pipeline are fixedly connected by bolts, if the sealing ring block is corroded, aged, or shrinks, resulting in poor sealing, the threaded rod can be rotated to drive the abutment bracket to slide to one end in the slide groove. The abutment pushes the abutment block to one end, thereby pushing the slider to slide away from the spring in the circular groove, causing the spring to be stretched open. At this time, the sealing ring block will be pushed outward to a certain height, so that the sealing ring blocks on the two irregular flange bodies deform and squeeze together, improving the sealing performance. Through this adjustment, the height of the sealing ring block can be adjusted multiple times, so that it can continue to be used for sealing even after aging and shrinkage, improving the sealing effect, reducing the replacement frequency, and increasing the service life.

[0008] Preferably, a plurality of protrusions are fixedly installed on the outer surface of one end of the threaded rod, wherein the plurality of protrusions are arranged at equal intervals.

[0009] The effect achieved by the above components is that by setting the protrusions, the contact area and friction of the outer surface of one end of the threaded rod can be increased, so that it will not slip in the hand when it is manually held and rotated.

[0010] Preferably, a limiting mechanism is provided between the protrusion and one side of the shaped flange body. The limiting mechanism includes a rotating rod, one end of which is rotatably mounted on one side of the shaped flange body and abuts against one side of the protrusion; a torsion spring, the inner wall of which is sleeved on the outer surface of one end of the rotating rod and both ends are fixedly mounted on one side of the rotating rod and one side of the shaped flange body, respectively; and a stop block, one side of which is fixedly mounted on one side of the shaped flange body and abuts against one side of the rotating rod.

[0011] The effect achieved by the above components is as follows: By setting a limiting mechanism, when one end of the threaded rod and several protrusions are held and the rod is rotated away from the stop block, the abutment frame will slide towards the abutment block and press against it. At this time, the protrusions will abut against the rotating rod as it rotates away from the stop block, causing the torsion spring to deform. When the protrusions are completely removed from one end of the rotating rod, the torsion spring will drive the rotating rod to return to its original position and abut against the side of the baffle. This will also abut against the protrusions, making it less likely for the adjusted threaded rod to reverse, improving the stability of the sealing ring block after adjustment, and improving the sealing effect.

[0012] Preferably, the sealing device further includes a plurality of telescopic rods, wherein the outer surface of the telescopic rods penetrates the inner wall of the spring, and both ends are fixedly installed on one side of the slider and one side of the inner wall of the circular groove, respectively.

[0013] The effect achieved by the above components is that by setting up the telescopic rod, the inner wall of the spring can be supported and reinforced, making it less prone to bending and damage during use.

[0014] Preferably, a plurality of round rollers are rotatably mounted on one side of the abutting block, wherein the round rollers are arranged on the side of the abutting block close to the abutting frame.

[0015] The effect achieved by the above components is that by setting the round roller, the wear between the abutment block and the abutment frame can be reduced, the abutment block can be pushed more easily, and the adjustment can be made more convenient.

[0016] Preferably, a bearing is fixedly installed on the outer surface of one end of the threaded rod, wherein the outer ring of the bearing is fixedly installed on one side of the inner wall of the groove.

[0017] The effect achieved by the above components is that by setting bearings, the rotational wear between the threaded rod and the inner wall of the groove can be reduced, making the rotation of the threaded rod easier and improving its service life.

[0018] The beneficial effects of this utility model are: By setting up a sealing device, when installing the main body of the irregular flange on the pipeline and then connecting the main bodies of the two irregular flanges on the pipeline with bolts, if the sealing ring block corrodes, ages, and shrinks, causing poor sealing, the threaded rod can be rotated to drive the abutment bracket to slide to one end in the slide groove. This abuts and pushes the abutment block to one end, thereby pushing the slider to slide away from the spring in the circular groove. This stretches the spring, pushing the sealing ring block outward to a certain height, causing the sealing ring blocks on the two irregular flange bodies to deform and squeeze together, improving the sealing performance. Through this adjustment, the height of the sealing ring block can be adjusted multiple times, allowing it to continue to seal even after aging and shrinkage, improving the sealing effect, reducing the replacement frequency, and extending the service life.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Figure 1-5 The superior sealing performance of the irregular flange shown includes an irregular flange body 1. A sealing device 2 is provided on one side of the irregular flange body 1. The sealing device 2 uses bolts to drive the abutment frame 27 to move and squeeze and push the abutment block 25, thereby driving the slider 23 and the sealing ring block 24 to slide out of the circular groove 21. The height of the sealing ring block 24 protruding on one side of the irregular flange body 1 is adjusted to achieve the effect of tightly fitting the gap between the two irregular flange bodies 1 and improving the sealing performance.

[0026] Figure 1-5The sealing device 2 shown includes a slider 23, a circular groove 21 on one side of the irregular flange body 1, a sliding groove 22 on the inner wall of the circular groove 21, wherein the outer surface of the slider 23 is slidably installed in the inner wall of the circular groove 21; a sealing ring block 24, wherein one side of the sealing ring block 24 is fixedly installed on one side of the slider 23 and inserted into the inner wall of the circular groove 21; several springs 26, wherein the two ends of the springs 26 are respectively fixedly installed on one side of the slider 23 and one side of the inner wall of the circular groove 21; two abutment blocks 25, wherein one side of the abutment block 25 is fixedly installed on the side of the slider 23 away from the sealing ring block 24; an abutment frame 27, wherein the abutment frame 27 is slidably installed in the inner wall of the sliding groove 22 and its two ends abut against one side of the two abutment blocks 25; and a threaded rod 28, wherein one end of the threaded rod 28 is installed through one side of the inner wall of the sliding groove 22 and its outer surface is threadedly connected to the inner wall of the abutment frame 27. By setting the sealing device 2, when the irregular flange body 1 is installed on the pipeline, and then the two irregular flange bodies 1 on the pipeline are fixedly connected by bolts, if the sealing ring block 24 is corroded, aged, and shrinks, resulting in poor sealing, the threaded rod 28 can be rotated to drive the abutment bracket 27 to slide to one end in the slide groove 22, abutting and pushing the abutment block 25 to one end, thereby pushing the slider 23 to slide away from the spring 26 in the circular groove 21, causing the spring 26 to be stretched open. At this time, the sealing ring block 24 will be pushed outward to a certain height, so that the sealing ring blocks 24 on the two irregular flange bodies 1 will deform and squeeze together, improving the sealing performance. Through this adjustment, the height of the sealing ring block 24 can be adjusted multiple times, so that it can continue to seal after aging and shrinkage, improving the sealing effect, reducing the replacement frequency, and increasing the service life.

[0027] Figure 1-5 Several protrusions 210 are fixedly installed on the outer surface of one end of the threaded rod 28 shown, and the protrusions 210 are arranged at equal intervals. By setting the protrusions 210, the contact area and friction of the outer surface of one end of the threaded rod 28 can be increased, so that it will not slip in the hand when it is manually held and rotated.

[0028] Figure 1-5A limiting mechanism 29 is provided between the protrusion 210 and one side of the irregular flange body 1. The limiting mechanism 29 includes a rotating rod 291, one end of which is rotatably mounted on one side of the irregular flange body 1 and abuts against one side of the protrusion 210; a torsion spring 292, the inner wall of which is sleeved on the outer surface of one end of the rotating rod 291 and both ends are fixedly mounted on one side of the rotating rod 291 and one side of the irregular flange body 1, respectively; and a stop block 293, one side of which is fixedly mounted on one side of the irregular flange body 1 and abuts against one side of the rotating rod 291. By setting the limiting mechanism 29, when one end of the threaded rod 28 and several protrusions 210 are held and rotated towards the side of the rotating rod 291 away from the stop block 293, the abutment frame 27 will slide towards the side of the abutment block 25, pressing the abutment block 25. At this time, the protrusions 210 will abut against the rotating rod 291 and rotate away from the stop block 293, causing the torsion spring 292 to deform. When the protrusions 210 are completely removed from one end of the rotating rod 291, the torsion spring 292 will drive the rotating rod 291 to return to the side of the baffle, which will also abut against the protrusions 210, making it less likely for the adjusted threaded rod 28 to reverse, improving the stability of the sealing ring block 24 after adjustment, and improving the sealing effect.

[0029] Figure 1-5 The sealing device 2 shown also includes several telescopic rods 211, the outer surface of which penetrates the inner wall of the spring 26, and both ends are fixedly installed on one side of the slider 23 and one side of the inner wall of the circular groove 21, respectively. By setting the telescopic rods 211, the inner wall of the spring 26 can be supported and reinforced, making it less prone to bending damage during use. Several circular rollers 212 are rotatably mounted on one side of the abutment block 25, with the rollers 212 positioned on the side of the abutment block 25 near the abutment frame 27. By setting the rollers 212, the abutment wear between the abutment block 25 and the abutment frame 27 can be reduced, facilitating the pushing and adjustment of the abutment block 25. A bearing 213 is fixedly installed on the outer surface of one end of the threaded rod 28, with the outer ring of the bearing 213 fixedly installed on one side of the inner wall of the slide groove 22. By setting the bearing 213, the rotational wear between the threaded rod 28 and the inner wall of the slide groove 22 can be reduced, facilitating the rotation of the threaded rod 28 and improving its service life.

[0030] Working principle: When installing the shaped flange body 1 on the pipeline, and then connecting the two shaped flange bodies 1 on the pipeline with bolts, if the sealing ring block 24 corrodes, ages, and shrinks, causing poor sealing, hold one end of the threaded rod 28 and several protrusions 210 and rotate it towards the side of the rotating rod 291 away from the stop block 293. This causes the abutment frame 27 to slide to one end in the slide groove 22, pushing the abutment block 25 to one end, thereby pushing the slider 23 to slide away from the spring 26 in the circular groove 21. This stretches the spring 26, pushing the sealing ring block 24 outward to a certain height, causing the sealing ring blocks 24 on the two shaped flange bodies 1 to deform and squeeze together, improving the sealing performance. By adjusting in this way, the height of the sealing ring block 24 can be adjusted multiple times, allowing it to continue to seal even after aging and shrinkage, improving the sealing effect, reducing the replacement frequency, and extending the service life. At this time, the protrusion 210 will abut against the rotating rod 291 and rotate to the side away from the stop block 293, causing the torsion spring 292 to deform. When the protrusion 210 is completely removed from one end of the rotating rod 291, the torsion spring 292 will drive the rotating rod 291 to reset and abut against the side of the baffle. This will also abut against the protrusion 210, making it less likely for the adjusted threaded rod 28 to reverse, improving the stability of the sealing ring block 24 after adjustment, and improving the sealing effect.
