Description

Technical Field

[0001] The utility model relates to the field of pipelines, in particular to a novel sealing flange. Background Art

[0002] In the modern industrial field, the sealing performance of pipeline connection is crucial. Generally, two pipelines are connected together because flange connection can provide a very firm connection, and flanges are usually made of high-strength metal materials such as carbon steel and stainless steel, which can withstand large pressures and tensile forces. However, when some flanges are in use, they are generally fixedly connected by multiple bolts and nuts. After long-term use, the bolts and nuts may be loosened due to external influences, resulting in reduced sealing performance.

[0003] After retrieval, Chinese Patent Publication No.: CN220470911U discloses a safety-fastening sealing flange, which includes a first flange plate and a second flange plate.

First through holes and second through holes are respectively opened at the tops of the first flange plate and the second flange plate. A fixing screw rod is inserted into the first through hole, and one end of the fixing screw rod passes through the second through hole. Fixing nuts are threadedly connected to both ends of the fixing screw rod. The outer walls of the bottoms of the two groups of fixing nuts are respectively in contact with the outer wall of the top of the first flange plate and the outer wall of the bottom of the second flange plate.

[0036] Refer to Figure 3 - Figure 4 、 Figure 7 , the anti-loosening component further includes a moving block 36. A square block is provided at the right end of the moving block 36 to ensure its horizontal sliding back and forth on the inner wall of the cylinder 32. The moving block 36 is slidably connected to the inner wall of the cylinder 32. A spring 37 is fixedly connected to the rear surface of the moving block 36. The spring 37 always pulls the moving block 36 backward through its own elasticity to ensure the anti-loosening effect of the anti-loosening cylinder 31. The rear end of the spring 37 is fixedly connected to the rear side of the inner wall of the cylinder 32. The rear surface of the round rod 34 is rotatably connected to the front surface of the moving block 36. A first chute 39 is provided on the upper side of the inner wall of the cylinder 32. The first chute 39 is in a horizontal state in the front and rear direction, while the second chute 310 has a certain arc. When the anti-loosening cylinder 31 does not completely overlap with the outer wall of the bolt 5, it can rotate to the left side of the cylinder 32 through the arc of the second chute 310, facilitating the worker to disassemble and assemble the nut. A second chute 310 is provided on the front side of the inner wall of the cylinder 32 adjacent to the first chute 39. The first chute 39 is communicated with the second chute 310.

[0037] Refer to Figure 4 、 Figure 6 - Figure 7 , a sliding rod 35 is fixedly connected to the upper surface of the rear end of the round rod 34. The sliding rod 35 slides on the inner walls of the first chute 39 and the second chute 310 and drives the round rod 34 to rotate along the arc of the second chute 310. The top end of the sliding rod 35 slides on the inner wall of the first chute 39, and the top end of the sliding rod 35 slides on the inner wall of the second chute 310.

[0038] Refer to Figure 2 、 Figure 4 、 Figure 6 , a sealing groove 6 is provided at the left end of the front surface of the first flange 1.

The sealing ring 38 is adapted to the sealing groove 6 to ensure the sealing effect and improve the protection performance. The sealing ring 38 contacts the inner wall of the sealing groove 6.

[0039] Refer to Figure 3 - Figure 5, a through hole 45 is provided at the front end of the left surface of the cylinder 32, the insertion rod 44 contacts the inner wall of the through hole 45, the driving assembly further includes a ring 43 capable of driving the round rod 34 to move horizontally back and forth, the ring 43 is fixedly connected to the right surface of the front end of the rectangular plate 41, and the outer wall of the front end of the round rod 34 is rotatably connected to the inner wall of the ring 43.

[0040] Working principle: During installation, first fix the flange one 1 and the flange two 2 with bolts 5. Before installing the flange one 1 and the flange two 2, first push the connecting ring 42 to make the rectangular plate 41 slide on the left surface of the cylinder 32. The rectangular plate 41 drives the round rod 34 to move through the ring 43. When the round rod 34 moves, the sliding rod 35 on the upper surface of its rear end slides in the first chute 39 on the inner wall of the cylinder 32. When the sliding rod 35 slides to the connection point of the first chute 39 and the second chute 310, continue to push the round rod 34, and the sliding rod 35 drives the round rod 34 to rotate along the arc of the second chute 310. The round rod 34 drives the anti-loosening cylinder 31 to rotate through the connecting plate 33, so that the anti-loosening cylinder 31 rotates from the position overlapping with the bolt 5 to the left side of the cylinder 32. Then, insert the right end of the insertion rod 44 into the inner wall of the through hole 45 at the front end of the left surface of the cylinder 32 to fix the position of the round rod 34. At this time, the nut can be installed on the bolt 5 and tightened.

[0041] After tightening the nut, pull out the insertion rod 44. Under the elastic action of the spring 37, the spring 37 pulls the moving block 36 to move backward, the moving block 36 drives the round rod 34 to move backward, and the round rod 34 drives the anti-loosening cylinder 31 to move backward through the connecting plate 33. The inner wall of the anti-loosening cylinder 31 is hexagonal and is adapted to the outer wall of the nut. After the anti-loosening cylinder 31 moves backward, it is sleeved outside the nut to fix the nut and prevent the nut from loosening. In addition, when the sealing ring 38 on the rear surface of the anti-loosening cylinder 31 contacts the inner wall of the sealing groove 6 at the left end of the front surface of the flange one 1, the connection between the bolt 5 and the nut can be sealed to prevent external dust or impurities from adhering to the connection and corroding and rusting, improving the protection performance.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
