Description

Technical Field

[0001] This utility model relates to the field of pipeline sealing technology, specifically a main reactor pipeline sealing device. Background Technology

[0002] The main engine reactor is the primary reactor in a ship's system. It is used in the propulsion and power generation systems and is typically connected to external systems through numerous pipelines for fluid transport.

[0003] Since fluid is being transported, it is necessary to ensure the airtightness between pipelines. However, most existing sealing devices are vertically connected, while the space inside the ship's cabin is small and the pipelines need to be bent frequently. Therefore, vertical sealing devices alone are insufficient to meet the usage requirements, and there is an urgent need for a flexible sealing device to achieve a sealed connection of the pipelines. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides the following technical solution: a sealing device for a main reactor pipeline, comprising a pipe body, a flexible connecting hose that can be bent arbitrarily connected between two pipe bodies, a connector fixedly installed at one end of the pipe body near the connecting hose, and mating seats fixedly installed at both ends of the connecting hose, a limiting component for easy installation and positioning provided between the connector and the mating seats, and an adjusting component for adjusting the included angle between the two pipe bodies provided between the ends of the two pipe bodies.

[0005] As an optimization, a sealing sleeve is fixedly installed inside the connector, and an annular groove is opened on the inner wall of the sealing sleeve. A sealing inner tube is fixedly installed in the center of the mating seat, and several rubber sealing rings are provided at equal intervals on the outer side of the sealing inner tube.

[0006] As an optimization, the outer side of the sealing sleeve is provided with an array of limiting grooves, and the inner wall of the docking seat is provided with a protruding limiting block corresponding to the limiting groove. The limiting block slides along the limiting groove. By sliding the limiting block aligned with the limiting groove, the limiting function can be achieved, which facilitates the limiting component to dock and limit the installation of the connector and the docking seat.

[0007] As an optimization, the internal corresponding limiting component of the connector has a socket, and a spring pin for locking the limiting component is provided in the middle of the connector and around the socket array.

[0008] As an optimization, the limiting component includes an array of threaded rods fixedly mounted on the outside of the docking seat, with a locking head fixedly mounted at the end of the threaded rod, and the spring pin includes a locking block that slides into the insertion hole, with a compression spring fixedly mounted at the end of the locking block.

[0009] As an optimization, the outer side of the threaded rod is helically fitted with an internal threaded tube, the end of the internal threaded tube is chamfered, and a knob is fixedly installed at the other end of the internal threaded tube.

[0010] As an optimization, the adjustment assembly includes a collar sleeved on the outside of the two tubes. A support lug is fixedly installed on the outer side of the middle part of the collar sleeve. A connecting seat is rotatably connected to the end of the support lug. A screw is fixedly installed on the outer end face of the connecting seat. A threaded cylinder is sleeved on the outer side of the two screws. The middle part of the threaded cylinder has a turning part to increase friction.

[0011] The beneficial effects of this utility model are:

[0012] 1. The sealing device for the main reactor pipeline, by inserting the inner sealing tube into the sealing sleeve, can compress the rubber sealing ring to deform it and embed it into the corresponding annular groove for sealing. Then, by inserting the clamp into the insertion hole, the clamp block will slide outward and compress the compression spring. Then, when the clamp moves to the end, the compression spring will drive the clamp block to reset and lock the clamp for limiting, thus facilitating the installation and sealing.

[0013] 2. The sealing device of the main reactor pipeline can be rotated by pinching and twisting the screw, which will cause the threaded cylinder to rotate on the outside of the screw. This will cause the connecting seats on both sides to move closer or further apart, thus causing the two pipes to deflect relative to each other and change the included angle between them. This allows for easy adjustment of the bending angle according to the actual situation, improving applicability.

[0014] 3. The sealing device of the main reactor pipeline, by turning the knob, will drive the internal threaded tube to rotate around the threaded rod, which will cause the internal threaded tube to be inserted into the insertion hole. As it rotates, the inclined surface of its end will press against the locking block, which will cause the locking block to slide outward, and thus no longer lock the locking head. At this time, the locking head can be pulled out, which makes it easy to disassemble. Attached Figure Description

[0020] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-2 A sealing device for a main reactor pipeline includes a pipe body 1, a flexible connecting hose 2 that can be bent arbitrarily connected between two pipe bodies 1, a connector 3 fixedly installed at one end of the pipe body 1 near the connecting hose 2, a docking seat 4 fixedly installed at both ends of the connecting hose 2, a limiting component for easy installation and positioning between the connector 3 and the docking seat 4, and an adjusting component 5 for adjusting the included angle between the two pipe bodies 1 between the ends of the two pipe bodies 1.

[0023] Please see Figure 1-2 A sealing sleeve 6 is fixedly installed inside the connector 3. An annular groove 7 is opened on the inner wall of the sealing sleeve 6. A sealing inner tube 8 is fixedly installed in the center of the mating seat 4. Several rubber sealing rings 9 are provided at equal intervals on the outer side of the sealing inner tube 8. When the two sides of the connector 3 and mating seat 4 are brought closer together, the sealing inner tube 8 will be inserted into the sealing sleeve 6, which will squeeze the rubber sealing rings 9 to deform and embed them in the corresponding annular grooves 7, thereby achieving a sealing effect.

[0024] Please see Figure 1-2The outer side of the sealing sleeve 6 is provided with an array of limit grooves 10. The inner wall of the docking seat 4 is provided with a protruding limit block corresponding to the limit groove 10. The limit block slides along the limit groove 10. By sliding the limit block aligned with the limit groove 10, the limit function can be achieved, which facilitates the limit assembly to dock and limit the installation of the docking joint 3 and the docking seat 4.

[0025] Please see Figure 2-3 The connector 3 has an insertion hole 11 corresponding to the limiting component inside, and spring pins for locking the limiting component are arranged in an array around the insertion hole 11 in the middle of the connector 3. The limiting component includes a threaded rod 12 fixedly installed in an array on the outside of the docking seat 4. A locking head 13 is fixedly installed at the end of the threaded rod 12. The spring pin includes a locking block 14 that slides into the insertion hole 11. A compression spring 15 is fixedly installed at the end of the locking block 14. By inserting the locking head 13 into the insertion hole 11, the locking block 14 will be squeezed to slide outward and the compression spring 15 will be compressed. Thus, when the locking head 13 moves to the end, the compression spring 15 will drive the locking block 14 to reset and lock the locking head 13 for limiting.

[0026] Please see Figure 2-3 The outer side of the threaded rod 12 is helically fitted with an internal threaded tube 16. The end of the internal threaded tube 16 is chamfered. The other end of the internal threaded tube 16 is fixedly installed with a knob 17. By rotating the knob 17, the internal threaded tube 16 is driven to rotate around the threaded rod 12, which will cause the chamfered end of the internal threaded tube 16 to press against the locking block 14, so it no longer locks the locking head 13. At this time, the locking head 13 can be pulled out for easy disassembly.

[0027] Please see Figure 4 The adjusting component 5 includes a clamping ring 18 that fits around the outside of the two pipe bodies 1. A support lug 19 is fixedly installed on the outer side of the middle part of the clamping ring 18. A connecting seat 20 is rotatably connected to the end of the support lug 19. A screw 21 is fixedly installed on the outer end face of the connecting seat 20. A threaded cylinder 22 is fitted on the outer side of the two screws 21. The middle part of the threaded cylinder 22 has a twisting part 23 that increases friction. By pinching the twisting part 23 and twisting it, the threaded cylinder 22 can be rotated outside the screw 21, which will pull the connecting seats 20 on both sides, thereby adjusting the included angle between the two pipe bodies 1, which can be easily adjusted according to the actual situation.

[0028] In use, first slide the inner wall limiting block of the docking seat 4 into the limiting groove 10, so that the sealing inner tube 8 is inserted into the sealing sleeve 6. This will squeeze the rubber sealing ring 9 to deform and embed it into the corresponding annular groove 7 for sealing. At the same time, the clamp head 13 will be inserted into the insertion hole 11, so the clamp block 14 will be squeezed to slide outward and the compression spring 15 will be compressed. Then, when the clamp head 13 moves to the end, the compression spring 15 will drive the clamp block 14 to reset and clamp the clamp head 13 for limiting.

[0029] Then pinch the screwing part 23 and screw it, which will drive the threaded cylinder 22 to rotate outside the screw 21, which will pull the connecting seats 20 on both sides, so that the two tubes 1 can be deflected relative to each other, thereby changing the included angle between them.

[0030] By turning the knob 17, the internal threaded tube 16 will rotate around the threaded rod 12, which will cause the internal threaded tube 16 to be inserted into the insertion hole 11. As it rotates, the inclined surface of its end will press against the locking block 14, which will cause the locking block 14 to slide outward, thus no longer blocking the locking head 13. At this time, the locking head 13 can be pulled out for easy disassembly.

[0031] In summary, the sealing device for the main reactor pipeline, by inserting the inner sealing tube 8 into the sealing sleeve 6, can compress the rubber sealing ring 9 to deform it and embed it into the corresponding annular groove 7 for sealing. Then, by inserting the clamp 13 into the insertion hole 11, the clamp block 14 will slide outward and compress the compression spring 15. Thus, when the clamp 13 moves to the end, the compression spring 15 will drive the clamp block 14 to reset and lock the clamp 13 for limiting, thereby facilitating the installation and sealing.

[0032] By pinching the screwing part 23 and turning it, the threaded cylinder 22 can be rotated outside the screw 21, which will cause the connecting seats 20 on both sides to move closer or further apart. Therefore, the two tubes 1 can be deflected relative to each other, thereby changing the included angle between them. This makes it easier to adjust the bending angle according to the actual situation and improves applicability.

[0033] Turning the knob 17 will cause the internal threaded tube 16 to rotate around the threaded rod 12, which will cause the internal threaded tube 16 to be inserted into the insertion hole 11. As it rotates, the inclined surface of its end will press against the locking block 14, which will cause the locking block 14 to slide outward, thus no longer blocking the locking head 13. At this time, the locking head 13 can be pulled out, making it easy to disassemble.
