Description
Technical Field
[0001] This utility model relates to the field of thermal pipeline connection technology, specifically to an energy-saving connection structure for thermal pipelines. Background Technology
[0002] In a thermal pipeline system, the pipe connection points are critical areas for heat loss and also important links affecting the system's stability and safety.
[0003] Traditional heating pipes are mostly connected by flanges. However, with the passage of time and the influence of the external environment, the nuts used to fix the flanges and bolts may loosen. This causes the bolts to move, resulting in a gap between the two sets of flanges and heat loss. Therefore, we need to propose an energy-saving connection structure for heating pipes. Utility Model Content
[0004] The purpose of this utility model is to provide an energy-saving connection structure for thermal pipelines, which avoids loosening of the connection between two sets of thermal pipelines and improves the connection sealing performance, thereby solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An energy-saving connection structure for thermal pipelines, comprising:
[0007] The heating pipe is provided in two sets, and flanges are welded to the outer walls of both sets of heating pipes. The flanges of the two sets are connected by long bolts.
[0008] A sealing sleeve is provided between two sets of flanges and is fitted onto the outer wall of one end of the two sets of thermal pipes.
[0009] The clamp mechanism is installed on the outer wall of the two sets of flanges. The clamp mechanism is equipped with an anti-slip mechanism. The clamp mechanism supports the anti-slip mechanism, and the anti-slip mechanism fixes the long bolts to prevent slippage due to loosening.
[0010] Preferably, there are six sets of long bolts, and the six sets of long bolts are arranged in a circular array on two sets of flanges respectively. A first nut is threaded onto the outer wall of one end of each of the six sets of long bolts.
[0011] Preferably, the clamp mechanism includes an upper clamp, a lower clamp, and a connecting component. One end of the upper clamp is rotatably connected to the lower clamp, and the upper clamp and the lower clamp are closedly connected through the connecting component.
[0012] Preferably, a rotating block is fixedly connected to one bottom end of the upper clamp, and a clearance groove adapted to the rotating block is provided at one top end of the lower clamp, and the rotating block is rotatably installed inside the clearance groove.
[0013] Preferably, the connecting assembly includes an upper connecting plate, a lower connecting plate, a flexible gasket, two sets of short bolts, and two sets of second nuts adapted to the short bolts. The upper connecting plate and the lower connecting plate are respectively welded to the outer walls of the upper clamp and the lower clamp. The flexible gasket is disposed on the top of the lower connecting plate. The upper connecting plate and the lower connecting plate are connected by two sets of short bolts and two sets of second nuts.
[0014] Preferably, the anti-slip mechanism includes six sets of housings, six sets of springs, six sets of fixing blocks, and six sets of anti-slip pads. The six sets of housings are fixedly connected to the inner walls of the upper and lower clamps in a circular array.

The six sets of anti-slip pads are respectively adhered to the six sets of fixing blocks, and the six sets of anti-slip pads are respectively in contact with the outer walls of the six sets of long bolts.

[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] This invention inserts two sets of heating pipes into the two ends of a sealing sleeve, and then fixes the two sets of flanges. When the two sets of heating pipes are connected, they squeeze the two sets of sealing rings respectively. The clamping mechanism is set on the outer wall of the two sets of flanges to apply a holding force to the flanges. At this time, the six sets of fixing blocks will abut against the outer wall of the six sets of long bolts under the support of the six sets of springs. The anti-slip pad increases the friction with the long bolts, which can prevent the long bolts from moving due to the loosening of the first nut, thus preventing the connection of the two sets of heating pipes from loosening and improving the connection sealing performance.

[0026] 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.
[0027] Please see Figure 1-6 This utility model provides a technical solution:
[0028] An energy-saving connection structure for a thermal pipeline includes: a thermal pipeline 1, which is provided in two sets, with flanges 2 welded to the outer walls of both sets of thermal pipeline 1, and the two sets of flanges 2 are connected by long bolts 3; a sealing sleeve 4, which is provided between the two sets of flanges 2, and the sealing sleeve 4 is fitted onto the outer walls of the opposite ends of the two sets of thermal pipeline 1; and a clamping mechanism 5, which is provided on the outer walls of the two sets of flanges 2, and the clamping mechanism 5 is provided with an anti-slip mechanism 6. The clamping mechanism 5 supports the anti-slip mechanism 6, and the anti-slip mechanism 6 fixes the long bolts 3 in an anti-slip manner, so as to prevent the long bolts 3 from sliding due to loosening.
[0029] In this embodiment, firstly, two sets of heat pipes 1 are inserted into the two ends of the sealing sleeve 4, then the two sets of flanges 2 are fixedly installed, and then the clamp mechanism 5 is set on the outer wall of the two sets of flanges 2. It is worth noting that when installing the clamp mechanism 5, the anti-slip mechanism 6 should be aligned with the long bolt 3 first, and the anti-slip mechanism 6 is used to fix the long bolt 3 to prevent it from slipping due to loosening.
[0030] There are six sets of long bolts 3, and the six sets of long bolts 3 are arranged in a ring array on two sets of flanges 2 respectively. The outer wall of one end of each of the six sets of long bolts 3 is threaded with a first nut 7.
[0031] In this embodiment, each of the two flanges 2 has six sets of mounting slots that are compatible with the long bolts 3. The six sets of long bolts 3 pass through the six sets of mounting slots on the two flanges 2 respectively, and the six sets of first nuts 7 are tightened on the six sets of long bolts 3 respectively to fix the two flanges 2 and then connect the two sets of thermal pipes 1.
[0032] The clamp mechanism 5 includes an upper clamp 51, a lower clamp 52 and a connecting component 53. One end of the upper clamp 51 is rotatably connected to the lower clamp 52, and the upper clamp 51 and the lower clamp 52 are closedly connected through the connecting component 53.
[0033] In this embodiment, both the upper clamp 51 and the lower clamp 52 are semi-circular, and the upper clamp 51 and the lower clamp 52 are combined to form a ring. The upper clamp 51 and the lower clamp 52 can be installed using the connecting component 53.
[0034] The bottom end of the upper clamp 51 is fixedly connected to a rotating block 54, and the top end of the lower clamp 52 is provided with a relief groove that matches the rotating block 54, and the rotating block 54 is rotatably installed inside the relief groove.
[0035] In this embodiment, the rotating block 54 is rotatably installed inside the relief groove. When the rotating block 54 rotates, it can drive the upper clamp 51 to rotate, thereby enabling the upper clamp 51 and the lower clamp 52 to rotate in opposite directions around the rotating block 54.
[0036] The connecting assembly 53 includes an upper connecting plate 531, a lower connecting plate 532, a flexible gasket 533, two sets of short bolts 534, and two sets of second nuts 535 adapted to the short bolts 534. The upper connecting plate 531 and the lower connecting plate 532 are respectively welded to the outer walls of the upper clamp 51 and the lower clamp 52. The flexible gasket 533 is disposed on the top of the lower connecting plate 532. The upper connecting plate 531 and the lower connecting plate 532 are connected by two sets of short bolts 534 and two sets of second nuts 535.
[0037] In this embodiment, the upper clamp 51 and the lower clamp 52 are rotated into a ring shape. At this time, the upper connecting plate 531 and the lower connecting plate 532 are in contact, and the flexible gasket 533 is located between the upper connecting plate 531 and the lower connecting plate 532. Two sets of short bolts 534 are passed through the upper connecting plate 531 and the lower connecting plate 532, and two sets of second nuts 535 are tightened on the two sets of short bolts 534 respectively. At this time, the upper connecting plate 531 and the lower connecting plate 532 are pressed against each other and squeeze the flexible gasket 533. The flexible gasket 533 is used to increase the contact area and disperse the pressure, making the upper clamp 51 and the lower clamp 52 more secure.
[0038] The anti-slip mechanism 6 includes six sets of housings 61, six sets of springs 62, six sets of fixing blocks 63, and six sets of anti-slip pads 64. The six sets of housings 61 are fixedly connected in a ring array to the inner walls of the upper clamp 51 and the lower clamp 52. The six sets of springs 62 are respectively fixedly installed inside the six sets of housings 61. One end of each of the six sets of springs 62 is fixedly connected to the six sets of fixing blocks 63. The six sets of anti-slip pads 64 are respectively bonded to the six sets of fixing blocks 63, and the six sets of anti-slip pads 64 are respectively attached to the outer walls of the six sets of long bolts 3.
[0039] In this embodiment, after the clamp mechanism 5 is installed, the six sets of fixing blocks 63 will abut against the outer wall of the six sets of long bolts 3 under the support of the six sets of springs 62, and the friction with the long bolts 3 will be increased by the anti-slip pad 64. This can prevent the long bolts 3 from moving due to the loosening of the first nut 7, prevent the connection of the two sets of heat pipes 1 from becoming loose, improve the connection sealing, and the springs 62 can reduce the vibration generated by the heat pipes 1, thus improving the vibration resistance.
[0040] It is worth noting that when the clamping mechanism 5 is installed, the clamping mechanism 5 will also come into contact with the outer walls of the two sets of flanges 2. At this time, a clamping force can be applied to the two sets of flanges 2 to further limit the movement of the two sets of flanges 2, prevent the two sets of flanges 2 from moving, and further improve the connection sealing of the two sets of thermal pipes 1.
[0041] Limiting grooves are provided on both sides of the inner wall of the housing 61. Limiting blocks 65 are slidably installed inside the two sets of limiting grooves. The two sets of limiting blocks 65 are fixedly connected to both sides of the fixing block 63 respectively.
[0042] In this embodiment, the fixing block 63 is limited by two sets of limiting blocks 65, which can prevent the fixing block 63 from falling out of the inside of the housing 61, and ensure that the fixing block 63 moves along the central axis.
[0043] A reinforcing ring 8 is provided on the inner wall of the sealing sleeve 4. Both ends of the reinforcing ring 8 are fitted with sealing rings 9. When the two sets of heat pipes 1 are connected, they will squeeze the two sets of sealing rings 9 respectively.
[0044] In this embodiment, after the two sets of heat pipes 1 are inserted into the two ends of the sealing sleeve 4, they will come into contact with the two sets of sealing rings 9 respectively. Then, when the two sets of flanges 2 are fixed, the two sets of heat pipes 1 will move toward the two sets of sealing rings 9, thereby squeezing the two sets of sealing rings 9, so that the two sets of sealing rings 9 seal the connection between the two sets of heat pipes 1.
[0045] Working principle: When using this utility model, firstly, two sets of heat pipes 1 are inserted into the two ends of the sealing sleeve 4. Then, six sets of long bolts 3 pass through the six mounting slots on the two sets of flanges 2 respectively, and six sets of first nuts 7 are tightened on the six sets of long bolts 3 to fix the two sets of flanges 2. Then, the two sets of heat pipes 1 are connected. At this time, the two sets of heat pipes 1 will move towards the two sets of sealing rings 9, thereby squeezing the two sets of sealing rings 9. Then, the clamp mechanism 5 is set on the outer wall of the two sets of flanges 2. After the clamp mechanism 5 is installed, the six sets of fixing blocks 63 will abut against the outer wall of the six sets of long bolts 3 under the support of the six sets of springs 62. The anti-slip pads 64 increase the friction with the long bolts 3, which can prevent the long bolts 3 from moving due to the loosening of the first nuts 7, thus preventing the connection of the two sets of heat pipes 1 from loosening and improving the connection sealing.
