Description

Technical Field

[0001] The invention relates to the field of heat exchange pipes, and more particularly to a heat exchange pipe for a building which is easy to maintain. Background Art

[0002] Building heat exchange pipes refer to the pipe system used to connect the heat source with the heat pipes inside the building in the building heating system. The building heat exchange pipe system uses efficient heat transfer equipment to enable the heating system to more accurately meet the heat demand inside the building, thereby improving the overall heating efficiency of the heating system and reducing the loss in the heat transmission process;

[0003] Before heating, the heat exchange pipes in buildings need to be cleaned and repaired, and wearing parts such as sealing rings need to be replaced to reduce the failure rate of the heat exchange pipes during operation. In order to improve the maintenance efficiency, some heat exchange pipes are usually installed by bolt connection. For example, the Chinese patent with the announcement number CN214250659U discloses a heat exchange pipe, in which the fixed tube sheet and the annular connection flange are connected by screws, which can reduce the difficulty of disassembly and assembly of the heat exchange pipe to a certain extent, thereby improving the maintenance and replacement efficiency of the heat exchange pipe.

[0004] Existing building heat exchange pipes are often installed and connected by flanges and bolts, and are sealed between two sets of flanges with sealing rings. When working, the sealing rings have a good sealing effect between the flanges due to thermal expansion and contraction. When the heat exchange system stops working, the water vapor remaining inside the heat exchange tube will cool and condense into water droplets remaining inside the heat exchange tube. At the same time, the temperature of the sealing ring decreases, which increases the gap between the sealing ring and the flange, thereby reducing the sealing of the connection between the two sets of flanges. The moisture inside the heat exchange tube will leak from the gap between the sealing ring and the flange. Long-term leakage will cause rust on the flange connection, thereby shortening the service life of the heat exchange tube. Summary of the invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a building heat exchange pipe that is easy to maintain.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 9 A building heat exchange pipe that is easy to maintain, comprising a mounting plate 12 and a mounting plate 2 13, wherein a heat exchange pipe 11 is fixedly connected to the outer surface of the left end of the mounting plate 12, and a placement groove 26 is provided on the outer surface of the right end of the mounting plate 12, and a sealing ring 23 is provided inside the placement groove 26, and an expansion component is provided inside the sealing ring 23;

[0035] The expansion component includes a second cavity 38 embedded in the sealing ring 23, an elastic plate 40 is fixedly connected to the inner surface of the second cavity 38, a fixed tube 39 is fixedly connected to the inner surface of the second cavity 38, a fixed cover 41 is fixedly connected to the upper and lower sides of the outer surface of the fixed tube 39, a capsule 42 is fixedly connected to the outer surface of the fixed cover 41 away from the fixed tube 39, and one end of the capsule 42 away from the fixed cover 41 is fixedly connected to the outer surface of the elastic plate 40, and the inner sides of the second cavity 38 and the fixed tube 39 are filled with hot expansion gas.

[0036] The cavity 2 38 is in the shape of a circular ring, the elastic plate 40 is in the shape of an arc and is symmetrically distributed on the upper and lower sides of the fixed tube 39, the number of the fixed tubes 39 is several groups and is distributed in a ring array, the sealing ring 23 is made of elastic high temperature resistant material, and a sealing groove 24 is provided on the outer surface of the right end of the sealing ring 23, and the sealing groove 24 is in the shape of a circular ring.

[0037] The outer surfaces of the mounting plate 1 12 and the mounting plate 2 13 are both provided with mounting holes 15 , the number of the mounting holes 15 is several groups and distributed in a ring array, the inner sides of the mounting holes 15 are provided with fastening bolts 14 , and the outer surface of the right end of the mounting plate 2 13 is fixedly connected with a conduit 17 .

[0038] By adopting the above technical solution, when the heat exchange tube 11 is installed, the mounting plate 12 at the right end of the heat exchange tube 11 is fitted on the outer surface of the mounting plate 2 13, and the conduit 17 for conveying the heat exchange medium is fixedly connected to the mounting plate 2 13, and then the fastening bolts 14 are passed through the mounting holes 15 on the surfaces of the mounting plate 12 and the mounting plate 2 13, and the mounting plate 12 and the mounting plate 2 13 are fastened and connected by the fastening bolts 14, so that the heat exchange tube 11 and the conduit 17 are connected to realize the stable flow of the heat exchange medium, and the placement groove 26 on the surface of the mounting plate 12 is used to accurately place the sealing ring 23. When the mounting plate 12 and the surface of the mounting plate 2 13 are fitted, the right surface of the sealing ring 23 will be tightly fitted on the outer surface of the mounting plate 2 13, and the sealing groove 24 can increase the friction between the sealing ring 23 and the mounting plate 2 13, thereby improving the sealing effect of the sealing ring 23 and reducing the probability of leakage of the heat exchange medium from between the sealing ring 23 and the mounting plate 2 13;

[0039] When the mounting plate 12 and the mounting plate 2 13 are kept in a fitted state, the left and right ends of the sealing ring 23 are kept in close contact with the mounting plate 1 12 and the mounting plate 2 13 respectively, and the cavity 2 38 inside the sealing ring 23 is used to place the elastic plate 40. Under the elastic force of the elastic plate 40, the left and right ends of the sealing ring 23 can be kept in an expanded state. With the continuous flow of the high-temperature medium, the stability of the mounting plate 1 12, the mounting plate 2 13 and the sealing ring 23 will increase accordingly. At this time, the thermal expansion gas inside the cavity 2 38 will expand due to the heat, so that the sealing ring 23 as a whole will be kept in a filled state, so that the sealing ring 23 and the mounting plate 1 12 and the mounting plate 2 13 can be more closely fitted. When the heat exchange tube 11 stops working, the residual steam in the pipeline will condense into water droplets and remain in the pipeline. The temperature of the sealing ring 23 and the mounting plate 1 12 and the mounting plate 2 13 will gradually decrease. At this time, the sealing ring 23 will gather and shrink inward under the action of thermal expansion and contraction, thereby causing the sealing ring 23 and the mounting plate 1 12 and the mounting plate 2 to be tightly connected. The gap between the two disks 13 increases, and the volume of the thermally expanded gas inside the fixed tube 39 will also decrease accordingly. Under the action of the gas pressure, the fixed tube 39 causes the bladder 42 to contract linearly through the fixed cover 41 on its surface, thereby pulling the middle part of the elastic plate 40 through the contraction of the bladder 42, causing the elastic plate 40 to flip from a bent state to a straight state, thereby squeezing the sealing ring 23 through the elastic plate 40, so that the sealing ring 23 always remains in an expanded state, so that the sealing ring 23 can always maintain a close fit with the surfaces of the mounting disk 1 12 and the mounting disk 2 13, reducing the probability of residual moisture in the pipeline leaking from the connection between the mounting disk 1 12 and the mounting disk 2 13, thereby improving the sealing of the installation connection of the heat exchange tube 11, and enabling the heat exchange tube 11 to maintain a good sealing effect during the alternating change between hot and cold, reducing the probability of leakage due to the thermal expansion and contraction of the sealing ring 23, thereby improving the safety of the heat exchange tube 11 during operation.

[0040] like Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, an extrusion assembly is provided on the inner side of the mounting plate 13, and the extrusion assembly includes an extrusion groove 22 opened on the outer surface of the right end of the mounting plate 12, and an extrusion plate 16 is fixedly connected to the outer surface of the left end of the mounting plate 13, and the extrusion plate 16 and the extrusion groove 22 are both annular, and the extrusion plate 16 is located on the right side of the extrusion groove 22, and the outer surface of the extrusion plate 16 is inclined.

[0041] A cavity 27 is embedded inside the mounting plate 12, and a movable plate 25 is slidably connected to the inner side of the mounting plate 12. One end of the movable plate 25 is located inside the extrusion groove 22 and the other end passes through the cavity 27. A guide groove 28 is provided on the inner surface of the cavity 27 away from the sealing ring 23. A movable plate 29 is slidably connected to the inner surface of the guide groove 28. A pin shaft 23 is fixedly connected to the outer surface of the movable plate 29, and a swing rod 34 is rotatably connected to the outer surface of the pin shaft 35.

[0042] The swing rod 34 is rotatably connected to the pin shaft 2 35 at one end away from the pin shaft 1 31, and the front and rear ends of the pin shaft 2 35 are fixedly connected to ear plates 46, and the outer surface of the ear plate 46 is fixedly connected to the top block 32 near the sealing ring 23. The inner surface of the cavity 1 27 is provided with a notch 30 near the sealing ring 23, and the inner surface of the notch 30 is fixedly connected to a sealing gasket 33, and the sealing gasket 33 is made of elastic material. The outer surface of the top block 32 is fixedly connected to the sealing gasket 33, and the top block 32 is in a circular ring shape. The outer surface of the movable plate 29 is in sliding contact with the swing rod 34.

[0043] By adopting the above technical solution, when the mounting plate 12 and the mounting plate 2 13 are close to each other, the extrusion plate 16 on the surface of the mounting plate 2 13 will enter the extrusion groove 22 on the surface of the mounting plate 12. At this time, the inclined surface of the extrusion plate 16 will squeeze the movable plate 25, so that the movable plate 25 slides into the cavity 1 27. The movable plate 25 will contact the swing rod 34 during the movement, and the swing rod 34 will be pushed by the movable plate 25. The guide groove 28 inside the cavity 1 27 is used to guide the sliding of the movable plate 29, so that the movable plate 29 slides linearly inside the guide groove 28. The movable plate 29 supports the swing rod 34 for rotation through the pin shaft 2 35, so that the angle of the swing rod 34 gradually flips. The swing rod 34 is connected to the pin shaft 1 31 and the swing rod 34 is connected to the movable plate 29 through the pin shaft 1 31. The ear plate 46 is supported by rotation. As the swing rod 34 gradually rotates, the swing rod 34 will push the top block 32 through the ear plate 46, and push the sealing gasket 33 through the annular top block 32, so that the sealing gasket 33 produces a certain degree of elastic deformation. The sealing gasket 33 will fit tightly on the outer surface of the sealing ring 23 under the extrusion of the top block 32. The friction between the sealing gasket 33 and the sealing ring 23 can be improved by squeezing the sealing gasket 33 and the sealing ring 23, which can not only effectively improve the sealing between the sealing ring 23 and the mounting disk 12, but also can further reduce the probability of leakage of the heat exchange medium in the heat exchange tube 11 from between the sealing ring 23 and the mounting disk 12, thereby effectively improving the stability and reliability of the heat exchange tube 11 during operation.

[0044] like Figure 3 and Figure 8 As shown, a clamping assembly is provided on the inner side of the mounting plate 12, and the clamping assembly includes a limiting groove 44 opened on the outer surface of the right end of the mounting plate 12, and the limiting groove 44 is connected to the inside of the placement groove 26, and a clamping plate 45 is slidably connected to the left end of the inner surface of the limiting groove 44, and the clamping plate 45 is in an arc shape.

[0045] A push rod 43 is fixedly connected to the side of the outer surface of the clamping plate 45 away from the sealing ring 23, and the push rod 43 is slidably connected to the mounting plate 12. The end of the push rod 43 away from the clamping plate 45 penetrates into the extrusion groove 22 and is in an arc shape. The inner surface of the extrusion plate 16 is in sliding contact with the push rod 43. The number of the push rods 43 and the clamping plates 45 is several groups and distributed in a ring array.

[0046] By adopting the above technical solution, when the extrusion plate 16 slides inside the extrusion groove 22, the extrusion plate 16 will squeeze the push rod 43, causing the push rod 43 to slide into the limiting groove 44. During the movement, the push rod 43 will drive the clamping plate 45 to move synchronously. The clamping plate 45 moves toward the sealing ring 23 inside the limiting groove 44, and then several groups of annularly distributed clamping plates 45 are attached to the outer surface of the sealing ring 23 to clamp the sealing ring 23, so that the sealing ring 23 always maintains a stable state during the operation, reducing the probability of accidental sliding of the sealing ring 23 in the placement groove 26, thereby ensuring the stability of the sealing ring 23.

[0047] like Figure 3 and Figure 5 As shown, a slow flow component is arranged on the inner side of the heat exchange tube 11, and the slow flow component includes an elastic paddle 19 fixedly connected to the inner surface of the heat exchange tube 11, the number of the elastic paddles 19 is several groups and distributed in a ring array, the elastic paddles 19 are in an arc shape, and the outer surface of the elastic paddle 19 is slidably connected to a movable tube 21, and the movable tube 21 is in a hollow arc shape.

[0048] A traction bar 20 is fixedly connected to the inner surface of the heat exchange tube 11. The traction bar 20 is fixedly connected to the movable tube 21 at one end away from the heat exchange tube 11. The traction bar 20 is made of elastic material. A stopper 36 is fixedly connected to the right end of the heat exchange tube 11. A stopper groove 37 is provided on the outer surface of the left end of the sealing ring 23. The stopper 36 and the stopper groove 37 are both distributed in a circular shape.

[0049] By adopting the above technical solution, the block 36 cooperates with the retaining groove 37 to limit the sealing ring 23. At the moment when the heat exchange tube 11 is started, the water flow will flow between the mounting plate 12 and the mounting plate 2 13. The water flow will impact the sealing ring 23 between the mounting plate 12 and the mounting plate 2 13 at the moment of flowing. The impact force of the water flow will increase the wear of the sealing ring 23 and shorten the service life of the sealing ring 23, thereby causing the sealing performance of the sealing ring 23 to decrease. For this purpose, a slow flow component is provided. When the water flow flows from the inside of the heat exchange tube 11 to the inside of the conduit 17, the water flow will first contact the elastic paddle 19, and the elastic paddle 19 will buffer the impact force of the water flow, so that the water flow can flow smoothly to the connection between the mounting plate 12 and the mounting plate 2 13, thereby reducing the impact of the water flow on the sealing ring 2 to a certain extent. 3, thereby extending the service life of the sealing ring 23 and making the sealing ring 23 always maintain a good sealing effect. At the same time, the movable tube 21 moves along the inner wall of the heat exchange tube 11 to the side away from the elastic paddle 19 under the action of the water flow, so that the elastic paddle 19 expands outward from the gathered state under the impact of the water flow, so that the water flow can flow through the gaps between each group of elastic paddles 19. The movable tube 21 will elastically deform the traction bar 20 during the movement. When the water flow inside the heat exchange tube 11 disappears, the movable tube 21 moves in the opposite direction under the elastic force of the traction bar 20. The movable tube 21 will slide in contact with the outer surface of the elastic paddle 19 during the movement, and drive a plurality of groups of annularly distributed elastic paddles 19 to gather together through the movable tube 21, so that the elastic paddle 19 completes the reset operation.

[0050] Method of use: When the heat exchange tube 11 is installed, the mounting plate 12 and the mounting plate 2 13 are fastened and connected by the fastening bolts 14, so that the heat exchange tube 11 is connected with the conduit 17 to realize the stable flow of the heat exchange medium. When the mounting plate 12 and the mounting plate 2 13 are close to each other, the inclined surface of the extrusion plate 16 will squeeze the movable plate 25, so that the movable plate 25 slides into the cavity 1 27, and the movable plate 25 pushes the swing rod 34 to turn the swing rod 34, and the swing rod 34 pushes the top block 32 through the ear plate 46. The sealing gasket 33 will fit tightly on the outer surface of the sealing ring 23 under the extrusion of the top block 32, which can effectively improve the sealing ring 23 and the mounting plate 12 between the outer surface of the sealing ring 23 and the mounting plate 1 In terms of sealing performance, the extrusion plate 16 will squeeze the push rod 43, and the push rod 43 will drive the clamping plate 45 to fit on the outer surface of the sealing ring 23 to clamp the sealing ring 23, so that the sealing ring 23 always remains in a stable state during the operation. When the mounting plate 12 and the mounting plate 2 13 remain in a fitted state, the sealing ring 23 is squeezed by the elastic plate 40, so that the sealing ring 23 always remains in an expanded state, so that the sealing ring 23 can always maintain a close fit with the surfaces of the mounting plates 12 and 13. At the moment of water flow, the impact force of the water flow is buffered by the elastic paddle 19, so that the impact of the water flow on the sealing ring 23 can be reduced to a certain extent, thereby extending the service life of the sealing ring 23.

[0051] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
