Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel pipes, in particular to a heat-insulating and pressure-resistant stainless steel pipe. Background Art

[0002] Stainless steel pipes are hollow-section pipes with a length greater than the diameter or circumference. They are widely used in transportation, engineering, thermal equipment, petrochemical industry, and other fields. Stainless steel pipes can also be used in plumbing pipes to transport hot water.

[0003] When in use, hot water temperature is easily lost due to stainless steel pipes when transporting water heating, causing the temperature of the hot water to drop when it is transported, affecting the user experience.

[0004] In order to overcome the above defects, the prior art (Chinese patent with publication number CN214947005U and application date 2021-02-05) provides a heat-insulating and pressure-resistant stainless steel pipe, comprising: an outer pipe; an inner pipe arranged inside the outer pipe; and a heat-insulating assembly arranged between the inner and outer pipes, suitable for heat-insulating the stainless steel pipe. The heat-insulating assembly is used to insulate the inner pipe, so that the stainless steel pipe has good heat-insulating capacity and structural strength, thereby making the stainless steel pipe less likely to freeze and crack when used in winter.

[0005] The above mechanism insulates the stainless steel pipe by using the insulation component to prevent the stainless steel pipe from freezing and cracking when used in winter. However, the insulation component of the above structure mainly uses asbestos to insulate and protect it, and asbestos can cause certain harm to the human body. Workers who have long-term contact with stainless steel pipes will also have excessive contact with asbestos, causing physical damage to the workers. Utility Model Content

[0006] The purpose of the utility model is to provide a heat-insulating and pressure-resistant stainless steel pipe to solve the problem raised in the above background technology that the hot water temperature is easily lost when the stainless steel pipe is used for water heating transportation, causing the temperature of the hot water to drop when it is transported, thus affecting the user experience.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a heat-insulating and pressure-resistant stainless steel pipe, comprising a stainless steel pipe body, the outer portion of the stainless steel pipe body is sheathed with an aluminum foil layer, and the outer portion of the aluminum foil layer is provided with a heat-insulating mechanism for reducing the temperature loss of hot water, the heat-insulating mechanism comprises a rock wool layer, and the rock wool layer is provided on the outer portion of the aluminum foil layer;

[0008] A pressure-resistant layer is arranged outside the rock wool layer, and a pressure-resistant mechanism for pressure-resistant protection is arranged inside the pressure-resistant layer.

[0009] Furthermore, the aluminum foil layer is tightly fitted to the outside of the stainless steel pipe body, and the inner side of the rock wool layer is tightly fitted to the outer side of the aluminum foil layer, and the lengths of the aluminum foil layer and the rock wool layer are consistent with the length of the stainless steel pipe body.

[0010] Furthermore, the pressure-resistant mechanism includes a support tube, and the support tube is snap-connected to the inside of the pressure-resistant layer, and a reinforcing rib is fixedly connected to the inside of the support tube.

[0011] Furthermore, the three corners of the reinforcing ribs are connected to the inner side of the support tube, and the support tubes are distributed at equal angles inside the pressure-resistant layer.

[0012] Furthermore, a protective mechanism for protecting the anti-pressure layer is arranged outside the anti-pressure layer, and the protective mechanism includes a protective layer, and the protective layer is sleeved outside the anti-pressure layer, and the outside of the protective layer is fixedly connected with a wear-resistant strip.

[0013] Furthermore, the upper end of one side of the protective layer is fixedly connected to a first mounting plate, and the lower end of one side of the protective layer is fixedly connected to a second mounting plate, the bottom end of the first mounting plate is provided with blocks distributed at equal intervals, and the bottom end of the block is rotatably connected to a limiting block, and the top end of the second mounting plate is provided with a limiting groove matching the limiting block.

[0014] Furthermore, the bottom end of the clamping block and the bottom end of the limiting groove are on the same horizontal line, and the bottom end of the limiting block passes through and extends to the bottom of the limiting groove.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. Water heating can be transported through the stainless steel pipe body. When the aluminum foil layer contacts the heat of water heating inside the stainless steel pipe body, it will quickly absorb the heat and reflect the heat back to the source, reducing heat loss, thereby transporting hot water more stably;

[0017] Furthermore, the rock wool layer can provide stable heat insulation performance, preventing the stainless steel pipe body from being overheated and scalding the user when conveying water and heating. After the rock wool layer is used for temperature insulation, the safety of the stainless steel pipe body during use is increased, and the rock wool layer itself has strong high temperature resistance and will not be damaged due to being in a high temperature state for a long time;

[0018] Furthermore, the rock wool layer can be wrapped and protected by the pressure-resistant layer to prevent the rock wool layer from being directly in contact with the outside world and causing damage. The pressure-resistant layer can also play a role in resisting pressure to prevent the stainless steel pipe body from being deformed and damaged after being impacted. The support pipe inside the pressure-resistant layer can fill the inside of the pressure-resistant layer and increase the pressure resistance of the pressure-resistant layer during use, effectively preventing the pressure-resistant layer from being deformed. The stability of the reinforcing ribs themselves can increase the impact resistance of the support pipe.

[0019] 2. Including the protective layer on the outside of the pressure-resistant layer can play a buffering role, reduce sharp impacts, and use the protective layer to reduce the friction damage on the outside of the pressure-resistant layer. At the same time, the protective layer can also play a certain role in sound insulation, which is convenient for the better use of the stainless steel pipe body. The wear-resistant strips can increase the wear resistance of the protective layer, thereby extending the service life of the protective layer;

[0020] Furthermore, since the protective layer is completely removable, it can be replaced in time when the protective layer is worn out after long-term use, thereby facilitating stable protection of the stainless steel pipe body. The limit block and the clamping block are rotatably connected. The clamping block is moved downward and the angle of the limit block is adjusted so that the angle of the limit block is the same as that of the limit groove. After the limit block passes through the limit groove, the limit block is rotated so that the limit block and the limit groove are misaligned, thereby fixing the position between the wear-resistant strip and the first mounting plate, thereby realizing the disassembly and assembly of the protective layer.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1:

[0030] like Figure 1 , Figure 2 and Figure 6 The technical solution shown is to solve the problem that hot water temperature is easily lost when stainless steel pipes are used for water heating transportation, resulting in a drop in temperature when hot water is transported, affecting the user experience: the heat-insulating and pressure-resistant stainless steel pipe discloses a heat-insulating mechanism, including a stainless steel pipe body 1, the outer part of the stainless steel pipe body 1 is sheathed with an aluminum foil layer 2, and the outer part of the aluminum foil layer 2 is provided with a heat-insulating mechanism for reducing hot water temperature loss, the heat-insulating mechanism includes a rock wool layer 3, and the rock wool layer 3 is arranged on the outside of the aluminum foil layer 2, the aluminum foil layer 2 is tightly attached to the outside of the stainless steel pipe body 1, and the inner side of the rock wool layer 3 is tightly attached to the outer side of the aluminum foil layer 2, and the lengths of the aluminum foil layer 2 and the rock wool layer 3 are consistent with the length of the stainless steel pipe body 1.

[0031] In this example, plumbing can be transported through the stainless steel pipe body 1. When the aluminum foil layer 2 comes into contact with the heat of the water heating transported inside the stainless steel pipe body 1, it will quickly absorb the heat and reflect the heat to the source to reduce heat loss. In addition, the rock wool layer 3 can provide stable heat insulation performance to prevent the stainless steel pipe body 1 from being overheated and scalding the user when transporting water. After the rock wool layer 3 is used for temperature insulation, the safety of the stainless steel pipe body 1 during use is increased, and the rock wool layer 3 itself has strong high temperature resistance and will not be damaged due to being in a high temperature state for a long time.

[0032] Embodiment 2:

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4The technical solution shown is to solve the problem of body wear caused by frictional contact between the stainless steel pipe body 1 and the outside: the heat-insulating and pressure-resistant stainless steel pipe discloses a protective mechanism, and a protective mechanism for protecting the pressure-resistant layer 4 is arranged on the outside of the pressure-resistant layer 4. The protective mechanism includes a protective layer 7, and the protective layer 7 is sleeved on the outside of the pressure-resistant layer 4. The outside of the protective layer 7 is fixedly connected with a wear-resistant strip 8, and the upper end of one side of the protective layer 7 is fixedly connected with a first mounting plate 9, and the lower end of one side of the protective layer 7 is fixedly connected with a second mounting plate 10. The bottom end of the first mounting plate 9 is evenly distributed with blocks 11, and the bottom end of the block 11 is rotatably connected to a limiting block 12. The top of the second mounting plate 10 is provided with a limiting groove 13 matching the limiting block 12, the bottom end of the block 11 and the bottom end of the limiting groove 13 are on the same horizontal line, and the bottom end of the limiting block 12 passes through and extends to the bottom of the limiting groove 13.

[0034] In this example, the protective layer 7 is included outside the pressure-resistant layer 4 to play a buffering role, reduce sharp impacts, and the protective layer 7 can reduce the friction damage outside the pressure-resistant layer 4. At the same time, the protective layer 7 can also play a certain sound insulation role, which is convenient for the better use of the stainless steel pipe body 1. The wear-resistant strips 8 can increase the wear resistance of the protective layer 7, thereby extending the service life of the protective layer 7;

[0035] Since the protective layer 7 is detachable as a whole, it can be replaced in time when the protective layer 7 is worn out after long-term use, thereby facilitating stable protection of the stainless steel pipe body 1. The limit block 12 and the clamping block 11 are rotatably connected. The clamping block 11 is moved downward and the angle of the limit block 12 is adjusted so that the angle of the limit block 12 is the same as that of the limit groove 13. After the limit block 12 passes through the limit groove 13, the limit block 12 is rotated so that the limit block 12 and the limit groove 13 are misaligned, thereby fixing the position between the wear-resistant strip 8 and the first mounting plate 9, thereby realizing the disassembly and assembly of the protective layer 7.

[0036] Embodiment three:

[0037] like Figure 1 , Figure 2 and Figure 5 The technical solution shown is to solve the problem that the stainless steel pipe body 1 is damaged by impact deformation and affects the water heating transmission efficiency: the thermal insulation and pressure-resistant stainless steel pipe discloses a pressure-resistant mechanism, a pressure-resistant layer 4 is arranged on the outside of the rock wool layer 3, and a pressure-resistant mechanism for pressure-resistant protection is arranged inside the pressure-resistant layer 4, the pressure-resistant mechanism includes a support tube 6, and the support tube 6 is snap-connected to the inside of the pressure-resistant layer 4, a reinforcing rib 5 is fixedly connected to the inside of the support tube 6, the three corners of the reinforcing rib 5 are connected to the inner side of the support tube 6, and the support tube 6 is distributed at equal angles inside the pressure-resistant layer 4.

[0038] In this example, the rock wool layer 3 can be wrapped and protected by the pressure-resistant layer 4 to prevent the rock wool layer 3 from being directly in contact with the outside world and causing damage. The pressure-resistant layer 4 can also play a pressure-resistant role to prevent the stainless steel pipe body 1 from being deformed and damaged after being impacted. The support tube 6 inside the pressure-resistant layer 4 can fill the interior of the pressure-resistant layer 4 and increase the pressure resistance of the pressure-resistant layer 4 during use, thereby effectively preventing the pressure-resistant layer 4 from being deformed. The stability of the reinforcement rib 5 itself can increase the impact resistance of the support tube 6.
