Description

Technical Field

[0001] This utility model relates to the field of steam heat pipe technology, and specifically to a low-loss steam heat pipe. Background Technology

[0002] A steam heating pipeline is a pipeline system used to transport high-temperature steam. Its principle is based on the high heat capacity of steam; steam is transported from its source to where heat is needed, such as heating equipment in industrial production or building heating systems. As the steam flows through the pipeline, it transfers its heat through the pipe walls to the surrounding environment or connected heat exchange equipment, thus achieving the purpose of heating.

[0003] Existing steam heating pipes typically require an insulation layer on the outside of the pipe. This insulation layer significantly hinders heat transfer. The low thermal conductivity of the insulation layer makes it difficult for heat to be quickly transferred to the external environment, thus ensuring that the temperature of the steam does not drop rapidly during long-distance transport within the pipe, allowing the steam to reach its destination with higher temperature and energy.

[0004] The insulation layer on existing steam heat pipes is usually fixed to the outer wall of the pipe by workers using bolts. However, the installation process requires workers to use tools to tighten the bolts multiple times to achieve the desired fixation. Similarly, when removing the insulation layer, workers need to tighten the bolts in the opposite direction multiple times. This makes the installation and removal of the insulation layer inconvenient, reducing the efficiency of workers when inspecting and maintaining the pipes and replacing the insulation material inside the insulation layer. Consequently, this leads to increased losses in the steam heat pipes. Utility Model Content

[0005] The purpose of this invention is to provide a low-loss steam heat pipe.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A low-loss steam heat pipe is provided, comprising a pipe body, an insulation mechanism, and a splicing mechanism. The insulation mechanism is fixedly installed on the pipe body and serves to insulate and protect the pipe body. The splicing mechanism is fixedly installed on the insulation mechanism and serves to open or close the insulation mechanism. The splicing mechanism includes a housing, a bidirectional telescopic rod, and a limiting mechanism. The housing is fixedly installed on the top of the insulation mechanism. The middle part of the bidirectional telescopic rod is rotatably installed inside the housing. The limiting mechanism is fixedly installed on the bidirectional telescopic rod and serves to limit the movement of the bidirectional telescopic rod.

[0008] Furthermore, the insulation mechanism includes an arc-shaped plate one, an arc-shaped plate two, an insulation block, and a retaining ring. The arc-shaped plate one is slidably connected to the arc-shaped plate two through an arc-shaped strip and a retaining block. The arc-shaped strip is fixedly connected to the arc-shaped plate two, and the retaining block is fixedly connected to the arc-shaped plate one. Both the arc-shaped plate one and the arc-shaped plate two can be slidably installed on the retaining ring. The retaining ring is fixedly installed on the pipe body. The insulation block can be installed and removed from the inner side of the arc-shaped plate one and the arc-shaped plate two.

[0009] Furthermore, the insulation mechanism also includes a sealing strip and an insert. The insert is fixedly installed on the first arc plate, and a slot is provided on the second arc plate. The sealing strip is fixedly installed on the inside of the slot. The insert is inserted into the inside of the slot. The top of the retaining ring is fixedly connected to the insertion mechanism. The insertion mechanism is used to open or close the first arc plate and the second arc plate.

[0010] Furthermore, the insertion mechanism also includes a first insertion rod, a second insertion rod, and a rotating rod. The first insertion rod is hinged to one end of the bidirectional telescopic rod, and the second insertion rod is hinged to the other end of the bidirectional telescopic rod. A through hole is provided on the first arc plate, and a through hole is provided on the second arc plate. The rotating rod is fixedly installed on the top of the bidirectional telescopic rod. The first insertion rod is inserted into the first through hole, and the second insertion rod is inserted into the second through hole.

[0011] Furthermore, the limiting mechanism includes a fixed block, a locking block, a collar, and a spring. The fixed block is fixedly installed on the rotating rod. The locking block is connected to the fixed block by a spring and is slidably connected to the fixed block. The collar is fixedly installed on the housing and has a limiting groove. The fixed block is rotatably connected to the collar, and the locking block engages with the limiting groove.

[0012] Furthermore, the housing is fixedly installed on the top of the retaining ring, and the housing passes through the first and second insertion rods. The top of the housing passes through the rotating rod and is rotatably connected.

[0013] The beneficial effects of this utility model are as follows: This low-loss steam heat pipe, through its insulation and insertion mechanisms, allows the bidirectional telescopic rod to move insertion rod one and insertion rod two to different positions when rotated to different angles. This enables arc plate one and arc plate two to be individually or simultaneously limited, facilitating the installation and removal of the insulation cotton. This improves the performance of the steam heat pipe and reduces its losses. In addition, the sealing strip in the insulation mechanism can seal arc plate one and arc plate two, preventing rainwater from entering the interior of arc plate one and arc plate two and eroding the insulation block, thereby improving the insulation effect and service life of the insulation block.

It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0025] Reference Figure 1 and Figure 2The diagram illustrates a low-loss steam heat pipe, comprising a pipe body 1, an insulation mechanism 2, and a connector 3. The insulation mechanism 2 is fixedly installed on the pipe body 1 and serves to insulate and protect the pipe body 1, reducing heat loss. The connector 3 is fixedly installed on the insulation mechanism 2 and is used to open or close the insulation mechanism 2. The connector 3 facilitates the installation and removal of the insulation block 28, thereby improving the working efficiency of the insulation mechanism 2. The connector 3 includes a housing 31, a bidirectional telescopic rod 32, and a limiting mechanism 38. The housing 31 is fixedly installed on the top of the insulation mechanism 2. The middle part of the bidirectional telescopic rod 32 is rotatably installed inside the housing 31, and both ends of the bidirectional telescopic rod 32 can extend or retract outward. The limiting mechanism 38 is fixedly installed on the bidirectional telescopic rod 32 and serves to limit the bidirectional telescopic rod 32, thereby limiting the insulation mechanism 2.

[0026] Refer to Figures 1 to 3 The insulation mechanism 2 includes an arc-shaped plate 21, an arc-shaped plate 22, an insulation block 28, and a retaining ring 29. The arc-shaped plate 21 is slidably connected to the arc-shaped plate 22 via an arc-shaped strip 26 and a retaining block 27. The sliding effect of the arc-shaped plate 21 and the arc-shaped plate 22 allows them to open or close. The arc-shaped strip 26 is fixedly connected to the arc-shaped plate 22, and the retaining block 27 is fixedly connected to the arc-shaped plate 21. The arc-shaped strip 26 and the retaining block 27 limit the sliding range between the arc-shaped plate 21 and the arc-shaped plate 22. To prevent the arc plate 1 21 from detaching from the arc plate 22, both arc plate 1 21 and arc plate 22 are slidably mounted on the retaining ring 29. The retaining ring 29 limits the movement of both sides of the arc plate 1 21 and arc plate 22. The retaining ring 29 is fixedly mounted on the pipe body 1. The insulation block 28 can be installed and removed from the inner side of the arc plate 1 21 and arc plate 22. There are two insulation blocks 28. By opening the arc plate 1 21 and arc plate 22, the two insulation blocks 28 can be installed on the inner side of the arc plate 1 21 and arc plate 22 respectively.

[0027] Reference Figure 2 and Figure 4The insulation mechanism 2 also includes a sealing strip 23 and an insert 25. The insert 25 is fixedly installed on the first arc plate 21. The second arc plate 22 has a slot 24. The sealing strip 23 is fixedly installed on the inner side of the slot 24. The sealing strip 23 is made of elastic material. When the insert 25 is inserted into the slot 24, it will squeeze the sealing strip 23, causing the sealing strip 23 to expand and seal the arc plate 21 and the second arc plate 22. The insert 25 is inserted into the inner side of the slot 24. When the insert 25 is inserted into the slot 24, the first arc plate 21 and the second arc plate 22 remain closed. The top of the retaining ring 29 is fixedly connected to the insertion mechanism 3. The insertion mechanism 3 is used to open or close the first arc plate 21 and the second arc plate 22.

[0028] Reference Figures 3 to 6 The insertion mechanism 3 also includes a first insertion rod 33, a second insertion rod 34, and a rotating rod 37. The first insertion rod 33 is hinged to one end of the bidirectional telescopic rod 32, and the second insertion rod 34 is hinged to the other end of the bidirectional telescopic rod 32. Through the rotation of the bidirectional telescopic rod 32, the first insertion rod 33 and the second insertion rod 34 move, thereby allowing the first insertion rod 33 to be inserted into or released from the through hole 35, and simultaneously allowing the second insertion rod 34 to be inserted into or released from the through hole 36. The arc-shaped plate 21 has... Through hole 35 is provided, and through hole 36 is provided on arc plate 22. Rotating rod 37 is fixedly installed on the top of bidirectional telescopic rod 32. By rotating the rotating rod 37, the bidirectional telescopic rod 32 can be rotated. Insert rod 33 is inserted into through hole 35. When insert rod 33 is inserted into through hole 35, it can limit the arc plate 21. Insert rod 34 is inserted into through hole 36. When insert rod 34 is inserted into through hole 36, it can limit the arc plate 22.

[0029] Reference Figure 6 and Figure 7 The limiting mechanism 38 includes a fixed block 381, a locking block 382, ​​a collar 383, and a spring 384. The fixed block 381 is fixedly mounted on the rotating rod 37. The rotation of the rotating rod 37 drives the fixed block 381 to rotate. The locking block 382 is connected to the fixed block 381 by the spring 384, and the locking block 382 is slidably connected to the fixed block 381. Through the elastic force of the spring 384, the locking block 382 remains engaged with the limiting groove 385 when no external force is applied, thereby limiting the fixed block. 381 is used to limit the movement, keeping the rotating rod 37 fixed. The collar 383 is fixedly installed on the housing 31, and the collar 383 has a limit groove 385. There are three limit grooves 385. The locking block 382 engages with the limit grooves 385 at different positions, thereby limiting the arc plate 1 21, or limiting the arc plate 22, or limiting both arc plate 1 21 and arc plate 22 at the same time. The fixing block 381 is rotatably connected to the collar 383, and the locking block 382 engages with the limit grooves 385.

[0030] Reference Figure 5 and Figure 7 The housing 31 is fixedly installed on the top of the retaining ring 29, and the housing 31 passes through the first insertion rod 33 and the second insertion rod 34. The retaining ring 29 supports and fixes the housing 31, and the housing 31 guides the first insertion rod 33 and the second insertion rod 34. The top of the housing 31 passes through and is rotatably connected to the rotating rod 37.

[0031] This low-loss steam heat pipe, through its insulation and insertion mechanisms, allows the bidirectional telescopic rod to move insertion rod one and insertion rod two to different positions when rotated to different angles. This enables arc-shaped plates one and two to be individually or simultaneously limited, facilitating the installation and removal of the insulation cotton. This improves the efficiency of the steam heat pipe and reduces its losses. In addition, the sealing strip in the insulation mechanism seals arc-shaped plates one and two, preventing rainwater from entering and corroding the insulation blocks, thus improving the insulation effect and service life of the insulation blocks.
