Description

Technical Field

[0001] This utility model belongs to the field of flange technology, specifically an adjustable flange connection assembly for irregular non-standard pipeline systems. Background Technology

[0002] A flange connection assembly is a device that enables reliable connection between pipes or equipment using components such as flanges, bolts, and gaskets. Its core structure consists of two perforated flanges, which are fastened with bolts and clamped together with an intermediate sealing gasket to form a rigid connection. This connection can withstand high-pressure fluid transmission and effectively prevent media leakage. With its standardized design, easy assembly and disassembly, and high sealing performance, this assembly has become a fundamental connection technology in the industrial field. Its applications cover petrochemicals (transporting high-risk media such as crude oil and natural gas), energy and power (steam pipelines, nuclear power equipment), shipbuilding (seawater pipeline systems), pharmaceuticals and food processing (hygienic clean pipelines), and other fields. It plays a key role, especially in systems that require frequent maintenance or withstand extreme operating conditions (high temperature, high pressure, strong corrosion).

[0003] An existing patent (publication number: CN219082519U) discloses a pipe flange connector. This connector uses a threaded connection, thereby improving the installation and disassembly efficiency of the flange connector. It is supported and fixed by a first support ring and a second support ring, and a first mounting seat and a second mounting seat, which further improves the stability of the flange connector after installation. Sealing rings are provided on both the first and second pipes, thereby improving the sealing performance of the pipes. However, this flange connector cannot quickly replace the inner ring with the corresponding shape according to the shape of non-standard pipes, resulting in its inability to connect with pipes of different shapes and its poor applicability. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides an adjustable flange connection assembly for non-standard pipeline systems, which effectively solves the problem that existing flange connectors cannot quickly replace the inner ring of the corresponding shape according to the shape of non-standard pipelines, resulting in the inability to connect with pipelines of different shapes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable flange connection assembly for a non-standard, irregularly shaped pipeline system, comprising an outer sleeve, with flange connecting plates fixedly installed at both ends of the outer sleeve surface. Each flange connecting plate has a plurality of bolt holes circumferentially spaced on its surface. An inner ring is inserted inside the outer sleeve, with a water-passing groove inside the inner ring. Both ends of the inner ring are fixedly installed with mating grooves, and sealing gaskets are fixedly installed inside each of the two mating grooves. A rotating ring is fitted in the middle of the outer sleeve surface, with transmission components on both sides of the rotating ring. Four slots are circumferentially spaced at both ends of the inner ring surface. Insert rods adapted to the slots are movably inserted circumferentially at both ends of the outer sleeve's circumferential surface. The transmission components are connected to the eight insert rods. When the rotating ring rotates, power is output to the eight insert rods through the transmission components, causing the eight insert rods to synchronously insert or withdraw from the corresponding slots for limiting or unlocking.

[0006] Preferably, the water passage, the docking groove, and the sealing gasket can be rectangular, circular, or elliptical in shape to match non-standard pipes.

[0007] Preferably, the surface of the rotating ring is fixedly equipped with several anti-slip ribs at equal intervals to prevent the hand from slipping during rotation. Two limiting slip rings are fixedly installed on the inner wall of the rotating ring, and two annular grooves are opened in the middle of the circumferential surface of the outer sleeve. The two limiting slip rings are slidably installed inside the two annular grooves.

[0008] Preferably, the transmission assembly includes eight slide rods, which are divided into two groups of four and fixedly installed at equal intervals on both sides of the rotating ring. Each slide rod is fitted with a sliding sleeve, and threaded rings are fixedly installed between the surfaces of the four sliding sleeves on the same side. Two threaded rings are threadedly connected to the surface of the outer sleeve through two external threads. Pushing buckets are fixedly installed on the sides of the two threaded rings that are far apart from each other.

[0009] Preferably, the inner walls of both pushing buckets are circumferentially and equidistantly fitted with four ball bearings. Each ball bearing has a rotating seat rotatably mounted on its surface. One end of each rotating seat is fixedly connected to the insert rod via a pressure plate. Each insert rod has a spring sleeved on its surface, and both ends of the spring are fixedly connected to the pressure plate and the outer sleeve, respectively.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: During adjustment, the operator rotates the rotating ring in the opposite direction through the anti-slip ribs. When the rotating ring rotates, it drives the two limiting slip rings to slide inside the two annular sliding grooves, which increases the stability of the rotating ring when it rotates. When the rotating ring rotates in the opposite direction, it drives the two threaded rings to rotate along the two external threads through the sliding rod and sliding sleeve, so that the two threaded rings rotate and move towards each other. When the two threaded rings move towards each other, they will release the pushing of the ball, and then push the pressure plate under the elastic force of the spring to make the insert rod exit the slot and release the limit. Then the inner ring is pulled out from the outer sleeve, thus quickly completing the disassembly.

[0011] Then, the operator inserts the inner ring to be replaced into the outer sleeve, and then rotates the rotating ring clockwise. When the rotating ring rotates clockwise, it drives the two threaded rings to move in opposite directions. When the two threaded rings move in opposite directions, they drive the two pushing buckets to move smoothly through the ball bearings, squeezing the pressure plate and the insert rod, and at the same time squeezing the spring of the insert rod. This gives the pressure plate and the insert rod the ability to elastically return to their original position. When the insert rod is squeezed and moved, it will insert into the slot for limited installation, thus quickly completing the replacement of the inner ring, making it possible to adapt to pipes of different shapes. This allows the flange connector to quickly replace the inner ring of the corresponding shape according to the shape of non-standard pipes, making it able to connect to pipes of different shapes, and its applicability is strong.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1 to 6 The present invention includes an outer tube 1, with flange connecting plates 2 fixedly installed at both ends of the surface of the outer tube 1. Several bolt holes 21 are circumferentially and equidistantly opened on the surface of both flange connecting plates 2. An inner ring 3 is inserted inside the outer tube 1, with a water-passing groove 4 inside the inner ring 3. A docking groove 5 is fixedly installed at both ends of the inner ring 3, and a sealing gasket 6 is fixedly installed inside each of the two docking grooves 5. A rotating ring 7 is fitted in the middle of the surface of the outer tube 1, with transmission components on both sides of the rotating ring 7. Four slots 12 are circumferentially and equidistantly opened at both ends of the surface of the inner ring 3. Insert rods 11, which are adapted to the slots 12, are movably inserted at both ends of the circumferential surface of the outer tube 1 at circumferentially and equidistantly. The transmission components are connected to the eight insert rods 11. When the rotating ring 7 rotates, the power is output to the eight insert rods 11 through the transmission components, causing the eight insert rods 11 to synchronously insert or withdraw from the corresponding slots 12 for limiting or unlocking.

[0023] The water passage trough 4, the docking groove 5, and the sealing gasket 6 can be rectangular, circular, or elliptical to match the shape of non-standard pipes. Several anti-slip ribs 8 are fixedly installed at equal intervals on the surface of the rotating ring 7 to prevent the hand from slipping during rotation. Two limiting slip rings 9 are fixedly installed on the inner wall of the rotating ring 7. Two annular grooves 10 are opened in the middle of the circumference of the outer sleeve 1. The two limiting slip rings 9 are slidably installed inside the two annular grooves 10.

[0024] During adjustment, the operator rotates the rotating ring 7 in the opposite direction through the anti-slip rib 8. When the rotating ring 7 rotates, it drives the two limiting slip rings 9 to slide inside the two annular sliding grooves 10, which increases the stability of the rotating ring 7 when it rotates. When the rotating ring 7 rotates in the opposite direction, it drives the insertion rod 11 to exit the slot 12 through the transmission component to release the limit. Then, the inner ring 3 is pulled out from the outer sleeve 1, thus quickly completing the disassembly.

[0025] Then, the operator inserts the inner ring 3 that needs to be replaced into the inner sleeve 1, and then rotates the rotating ring 7 in the forward direction. When the rotating ring 7 rotates in the forward direction, it drives the transmission component to operate. When the transmission component operates, it drives the insertion rod 11 to be inserted into the slot 12 for limiting installation, thereby quickly completing the replacement of the inner ring 3, making it possible to adapt to pipes of different shapes. This allows the flange connector to quickly replace the inner ring of the corresponding shape according to the shape of the non-standard pipe, so that it can be connected to pipes of different shapes, and its applicability is strong.

[0026] The transmission assembly includes eight slide rods 13. The eight slide rods 13 are divided into two groups of four and are fixedly installed on both sides of the rotating ring 7 at equal distances. Each slide rod 13 is fitted with a slide sleeve 14. Threaded collars 15 are fixedly installed between the surfaces of the four slide sleeves 14 on the same side. Two threaded collars 15 are threadedly connected to the surface of the outer sleeve 1 through two external threads 17. Push buckets 16 are fixedly installed on the side of the two threaded collars 15 that are far apart from each other.

[0027] The inner walls of the two pushing buckets 16 are each circumferentially and equidistantly fitted with four balls 22. The surfaces of the balls 22 are each rotatably mounted with a rotating seat 18. One end of the rotating seat 18 is fixedly connected to the insert rod 11 via a pressure plate 19. The surface of the insert rod 11 is fitted with a spring 20. Both ends of the spring 20 are fixedly connected to the pressure plate 19 and the outer sleeve 1, respectively.

[0028] When the rotating ring 7 rotates in the opposite direction, it drives the two threaded rings 15 to rotate along the two external threads 17 through the sliding rod 13 and the sliding sleeve 14, so that the two threaded rings 15 rotate and move towards each other. When the two threaded rings 15 move towards each other, they will release the pushing on the ball 22, and thus push the pressure plate 19 under the elastic force of the spring 20 to make the insert rod 11 exit the inside of the slot 12 and release the limit. Then the inner ring 3 is pulled out from the outer sleeve 1, thus quickly completing the disassembly.

[0029] When the rotating ring 7 rotates in the forward direction, it drives the two threaded rings 15 to move in opposite directions. When the two threaded rings 15 move in opposite directions, they will drive the two pushing buckets 16 to smoothly squeeze the pressure plate 19 and the insertion rod 11 through the ball bearing 22, and at the same time squeeze the spring 20 of the insertion rod 11, so that the pressure plate 19 and the insertion rod 11 have the ability to elastically return to their original position. When the insertion rod 11 is squeezed and moved, it will be inserted into the slot 12 for limited installation.
