Description

Technical Field

[0001] This invention relates to the field of pipe connector technology, specifically a novel pipe connector for pipe connection. Background Technology

[0002] Currently, during the construction and laying of water supply, drainage, oil transportation, and other fluid pipelines, it is necessary to connect to the flange ends of valves, filters, and other devices. When connecting pipelines without flanges, the traditional connection method is to weld an independent flange at the pipeline end for connection with the flanges of valves and other equipment. This method is costly and inefficient. For example, invention patent CN104315277A discloses a pipeline connector, including a connecting sleeve that fits on the outer circumference of the joint between two pipelines, two flanges at both ends of the connecting sleeve, two sealing rings positioned between the end faces of the connecting sleeve and the flanges, and a locking mechanism that locks the flanges to create a seal. This invention achieves a good seal through the cooperation of the flanges, sealing rings, and locking mechanism. However, when connecting pipelines of different materials, there will be a certain thickness difference between the walls of the two pipelines, resulting in an inconsistency in the outer diameters of the two pipelines. This invention cannot achieve pipeline compensation and cannot meet the requirements for pipeline connection strength and high compatibility. Therefore, it does not meet the current needs. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a novel pipe connector for pipe connection, solving the technical problem that existing devices cannot achieve pipe compensation functions.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a novel pipe connector for pipe connection, comprising a sleeve, both ends of which are fixedly connected to flanges, a downward bevel opening inside the flange, a sealing ring inserted into the downward bevel opening, an insertion groove inside the sealing ring, a plurality of adjusting pieces inserted into the insertion groove, a plurality of locking blocks installed on the sealing ring and located inside the plurality of adjusting pieces, a pressure flange installed on the flange, an upward bevel opening inside the pressure flange, and the upper ends of the plurality of adjusting pieces all contacting the upward bevel opening.

[0005] Preferably, a first groove is formed on one side wall of each of the plurality of adjusting plates, and a limiting protrusion is fixedly attached to one side wall of each of the plurality of locking blocks, the limiting protrusion being inserted into the first groove.

[0006] Preferably, the sealing ring has an annular groove, a plurality of limiting blocks are fixedly connected in the annular groove, the lower ends of the plurality of locking blocks are inserted into the annular groove, and a second groove is formed on the other side wall of the plurality of locking blocks, the second groove matching the limiting block.

[0007] Preferably, the number of the locking blocks is equal to the number of the limiting blocks.

[0008] Preferably, barbs are fixed to the other side wall of each of the locking blocks.

[0009] Preferably, a first protruding edge is fixedly attached to the inner wall surface of the sealing ring, and a second protruding edge is fixedly attached to the side wall surface of the sealing ring near the lower inclined opening.

[0010] Preferably, the flange has two pairs of threaded holes on the outside of the lower bevel, and the pressure flange has two pairs of through holes on the outside of the upper bevel. Bolts are inserted into both pairs of through holes, and one end of the bolt is screwed into the threaded hole.

[0011] Preferably, the sealing ring is made of EPDM rubber, and the adjusting plates are all made of plastic.

[0012] Beneficial effects

[0013] This invention provides a novel pipe connector for pipe connection, which has the following advantages: A bolt drives a flange to press several adjusting plates together. These adjusting plates can retract inwards under the action of the upper and lower bevels, forming an adjustable ring with a variable diameter. The adjusting ring pushes a locking block to tighten the inserted pipe. Simultaneously, the adjusting plates press a sealing ring to provide a seal. The barbs on the locking block generate a locking force on the inserted pipe, preventing it from being pulled off the device under high pressure or water hammer. The wedge-shaped first and second convex edges on the sealing ring improve the sealing effect and increase the sealing pressure after bolt pre-tightening. The internal dimensions of the connector are larger than the connected pipe, allowing for an angular deviation of ±5 degrees between the pipes, thus correcting radial angular deviations in pipe connections. The longer sleeve also provides radial compensation of 0-12 cm in pipe connections. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-10This invention provides a technical solution: a novel pipe connector for pipe connection, comprising a sleeve 1, with flanges 2 fixedly connected to both ends of the sleeve. A downward bevel 3 is formed within the flange 2, and a sealing ring 4 is inserted into the downward bevel 3. An insertion groove 5 is formed within the sealing ring 4, and several adjusting pieces 6 are inserted into the insertion groove 5. Several locking blocks 7 are installed on the sealing ring 4 and located inside the adjusting pieces 6. A pressure flange 8 is installed on the flange 2, and an upward bevel 18 is formed within the pressure flange 8. The upper ends of the adjusting pieces 6 are in contact with the upward bevel 18. A first groove 14 is formed on one side wall of each adjusting piece 6, and a limiting protrusion 15 is fixedly connected to one side wall of each locking block 7, the limiting protrusion 15 being inserted into the first groove 14. An annular groove 17 is formed on the sealing ring 4, and a locking block 7 is fixedly connected to the locking block 7. A plurality of limiting blocks 13 are connected, and the lower ends of a plurality of locking blocks 7 are inserted into the annular groove 17. A second groove 16 is provided on the other side wall of each of the locking blocks 7, and the second groove 16 matches the limiting block 13. The number of locking blocks 7 is equal to the number of limiting blocks 13. A barb 10 is fixedly attached to the other side wall of each of the locking blocks 7. A first protrusion 11 is fixedly attached to the inner wall of the sealing ring 4, and a second protrusion 12 is fixedly attached to the side wall of the sealing ring 4 near the lower inclined opening 3. Two pairs of threaded holes are provided on the flange 2 and outside the lower inclined opening 3. Two pairs of through holes are provided on the pressure flange 8 and outside the upper inclined opening 18. Bolts 9 are inserted into the two pairs of through holes, and one end of the bolts 9 is screwed into the threaded holes. The sealing ring 4 is made of EPDM rubber, and the adjusting plates 6 are all made of plastic.

[0027] Example: According to the appendix of the instruction manual Figure 1-10 As can be seen, during use, the pipe to be connected is inserted into the sleeve 1 through the flange 8, and the bolt 9 is tightened by using a wrench. The bolt 9 drives the flange 8 to press several adjusting plates 6. The adjusting plates 6 can retract inward under the action of the upper inclined port 18 and the lower inclined port 3. The several adjusting plates 6 can form an adjusting ring with a variable diameter. The adjusting ring pushes the locking block 7 to clamp the inserted pipe. At the same time, the several adjusting plates 6 press the sealing ring 4 to provide a seal. The barbs 10 on the locking block 7 can generate a locking force on the inserted pipe to prevent the inserted pipe from being pulled off the device under high pressure or water hammer. The first convex edge 11 and the second convex edge 12 of the wedge-shaped surface on the sealing ring 4 can improve the sealing effect and increase the sealing pressure after the bolt is pre-tightened. Because the internal size of the body is larger than the pipe to be connected, it can allow an angular deviation of ±5 degrees between the connected pipes, which can correct the radial angular deviation phenomenon in the pipe connection. The longer sleeve 1 can also play a radial compensation role of 0-12CM in the pipe connection.
