Description

Quick-release pipe insulation cover Technical Field

[0001] This invention relates to the field of pipe insulation technology, and more particularly to a quick-release pipe insulation cover. Background Technology

[0002] Quick-release pipe insulation covers are external insulation devices in the field of pipeline thermal management. The quick-release feature refers to their convenient operation in scenarios involving periodic pipeline inspection and maintenance. These devices are key components in pipeline systems used to prevent heat exchange between the pipeline and the external environment and to maintain the stable temperature of the medium being transported within the pipeline. They are widely used in industrial steam transmission pipelines, chemical medium transfer pipelines, and residential central heating pipelines. They serve both the energy efficiency and loss control requirements of pipeline systems and are suitable for practical applications such as daily pipeline operation and maintenance and component repair. They are a typical specialized device that combines the needs of pipeline thermal management with ease of operation and maintenance.

[0003] The above-mentioned and existing related technologies often have the following defects: most existing thermal insulation garments are single, interconnected cavities without effective anti-convection separation structures. When the inner wall of the thermal insulation garment cannot fit tightly against the pipe, it is very easy to cause significant thermal convection circulation due to the temperature gradient between the pipe and the outside, resulting in a significant increase in heat conduction loss. Especially in the case of irregularly shaped pipes, due to poor cavity fit and more intense convection, the thermal insulation efficiency is further reduced. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing technology has the disadvantage that most thermal insulation clothing is a single cavity that is fully connected, and the inner wall of the thermal insulation clothing cannot be tightly attached to the pipe. To this end, we propose a quick-disassembly pipe thermal insulation clothing.

[0005] To achieve the above objectives, this application adopts the following technical solution: a quick-release pipe insulation garment, including a heating pipe, an insulation component is fitted on the outside of the heating pipe, the insulation component includes an insulation garment body, an elastic band one is fixedly installed at the first end of the insulation garment body, an elastic band two is fixedly installed at the connecting end of the insulation garment body, and an elastic band three is fixedly installed at the connecting end of adjacent insulation garment bodies.

[0006] The thermal insulation garment is composed of an outer layer and an inner layer. An air-filled interlayer is reserved between the outer layer and the inner layer. Each outer layer has a flow groove inside. An air pump is fixedly installed on the outer side of the elastic band installed at the head end of the thermal insulation garment. A connecting pipe is fixedly installed on the exhaust end of the air pump. The connecting pipe is connected to the outer layer on one side of the elastic band. Gas flows into the flow groove through the connecting pipe.

[0007] The interior of each outer layer is also provided with multiple sets of vent holes, which are connected to the first flow channel. The upper part of the interior of each outer layer is also provided with a second flow channel, which is connected to the first flow channel. The outer layers of two adjacent insulation units are connected through the second flow channel.

[0008] Preferably, a connecting pipe 2 is provided on the outer side of the outer sleeve adjacent to the second elastic band, and a one-way valve 1 is provided on the connecting pipe 2. A connecting pipe 3 is provided on the outer side of the outer sleeve adjacent to the third elastic band, and a one-way valve 2 is provided on the connecting pipe 3. One end of the connecting pipe 2 and the connecting pipe 3 are threaded together.

[0009] Preferably, multiple sets of engaging components are fixedly installed on the outer side of the second elastic band, and a buckle matching the engaging components is fixedly installed on the outer side of the third elastic band.

[0010] Preferably, the locking component is fixedly connected to the elastic band 2, the inner side of the locking component is provided with a locking groove, the inside of the locking groove is provided with a limiting groove, and the inside of the limiting groove is provided with multiple sets of round holes.

[0011] Preferably, a limiting plate is rotatably installed inside the limiting groove, and torsion springs are fixedly installed on both sides of the limiting plate. One end of the torsion spring is fixedly installed inside the limiting groove, and a reset rod is fixedly installed on one end of the limiting plate.

[0012] Preferably, multiple sets of limiting rods are rotatably installed at the lower end of the limiting plate. The limiting rods match the circular holes, and the lower ends of the limiting rods pass through the locking parts and are slidably connected to them.

[0013] Preferably, the elastic band 2 has a connecting groove 1 at the position corresponding to the limiting rod, and the connecting groove 1 is slidably connected to the limiting rod.

[0014] Preferably, the elastic band 2 is further provided with a connecting groove 2, which is connected to the connecting groove 1 and is also connected to the flow groove 2.

[0015] Preferably, a buckle plate is installed on one side of the buckle, the buckle plate matches the buckle groove, and a limit groove is opened at the lower end of the buckle plate, the limit groove matches the limit plate.

[0016] Preferably, aerogel powder is pre-placed in the air-filled interlayer of both the outer and inner sleeves.

[0017] The technical effects and advantages of this invention are as follows:

[0018] In this invention, a segmented independent thermal insulation unit design is adopted. By dividing the air-filled interlayer of each unit into honeycomb-shaped independent air chambers using a high-frequency heat-sealing process, and in conjunction with the aerogel powder pre-placed within the unit, a dual anti-convection structure is formed with physical separation and a suspended solid thermal insulation medium, fundamentally blocking the lateral and longitudinal flow of air. At the same time, the outer layer is made of composite aluminized fabric with both airtightness and morphological stability, integrally molded to fit the contour of irregularly shaped pipes, while the inner layer uses a high-resilience composite fabric. By using an air pump to inflate the inner layer, it is uniformly compressed from its initial state of being attached to the outer layer. The insulation layer tightly wraps around the outer wall of the pipe to form a zero-gap pleated fit structure, completely eliminating the convection gap between the pipe and the insulation layer. The units are connected by air passage components and one-way valves to achieve air passage and leak-proof isolation. With the help of mechanical buckles and air pressure assistance after inflation, the sealing stability of the connection parts is ensured in the case of irregular pipes. Finally, through the structural synergy of independent air chamber to prevent convection, high elastic material to fit irregular shapes, aerogel to enhance heat insulation, and segmented sealing to maintain pressure, a high-efficiency insulation system with no convection gap and adaptable to irregular pipes is built, which significantly reduces heat conduction loss.

[0033] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0034] Referring to Figure 1, the present invention provides a technical solution: a quick-release pipe insulation cover, including a heating pipe 1, with an insulation component 2 covering the outside of the heating pipe 1. By covering the outside of the heating pipe 1 with the insulation component 2, the heat exchange between the heating pipe 1 and the external environment can be effectively blocked, the heat of the heating medium inside the pipe can be firmly locked, the temperature of the outer surface of the pipe can be kept within a reasonable range, the heat loss can be significantly reduced, and the heat transfer efficiency and energy economy of the heating system can be guaranteed.

[0035] Referring to Figures 1-3, in this embodiment: the insulation component 2 includes an insulation body 21. An elastic band 22 is fixedly installed at the first end of the insulation body 21, and an elastic band 23 is fixedly installed at the connecting end of the insulation body 21. The insulation body 21 adopts an assembly structure in which multiple independent units are connected in series along the axial direction of the heating pipe 1. An elastic band 24 is fixedly installed at the connecting end of adjacent insulation bodies 21. Each unit cooperates with the quick connection mechanism on the elastic band 22 and the elastic band 24 to form a complete insulation body 21 covering the target insulation area of ​​the pipe. When any unit is damaged or aged and needs to be replaced, the damaged unit can be disassembled and replaced separately without disassembling the entire insulation body 21 or affecting the insulation function of other intact units. This enables rapid repair and partial replacement of damaged parts, effectively reducing operation and maintenance costs and ensuring the continuous and stable operation of the overall insulation system.

[0036] Referring to Figures 2-4, in this embodiment: the thermal insulation garment body 21 is composed of an outer layer 211 and an inner layer 2111. An inflatable interlayer is reserved between the outer layer 211 and the inner layer 2111. The outer layer 211 is made of double-sided TPU coated aramid composite aluminized fabric integrally molded into a conical structure. This material has excellent air tightness, tear resistance and heat radiation reflection function, which can stably maintain the conical shape and adapt to the contour requirements of irregular pipes.

[0037] The inner sleeve 2111 is made of high-resilience liquid silicone composite spandex elastic fabric. With its excellent shape memory effect and high elasticity, it fits tightly against the inner curved surface of the outer sleeve 211 in its natural state. The material of the inner sleeve 2111 has a wide temperature range and is also anti-slip and wear-resistant. It can not only form a structural synergy with the conical outer sleeve 211, but also lay the foundation for subsequent air inflation and bonding to the surface of the heating pipe 1, effectively ensuring the interlayer sealing performance. Together with the heat reflection function of the outer sleeve 2111 and the bonding and sealing effect of the inner sleeve 2111, they jointly construct a highly efficient heat insulation barrier that blocks heat conduction, heat convection and heat radiation.

[0038] Referring to Figures 2-4, in this embodiment: the thermal insulation garment body 21 is composed of multiple sets of thermal insulation unit bodies connected in series along the pipe axis, and each set of thermal insulation unit bodies is formed by an outer sleeve 211 and an inner sleeve 2111.

[0039] The air-filled interlayers formed between the inner and outer layers of each insulation unit are interconnected by pipes, and the interior of the air-filled interlayer of each insulation unit is divided into independent air chambers by a high-frequency heat sealing process.

[0040] This design ensures that airflow can be evenly distributed to the air chambers of all units during inflation, while the independent air chamber structure restricts the lateral and longitudinal flow of air within the interlayer, effectively preventing heat convection. At the same time, each group of units is tightly spliced ​​together by a quick-connect mechanism to ensure the overall structure's airtightness. Combined with the high airtightness of the outer layer material and the tight sealing effect of the inner layer, a stable static insulation space is ultimately formed, significantly improving the thermal insulation efficiency.

[0041] Referring to Figures 2-6, in this embodiment: each outer sleeve 211 has a flow groove 212 inside. An air pump 221 is fixedly installed on the outside of the elastic band 22 installed at the head end of the thermal insulation garment body 21. The air pump 221 has inflation and deflation functions. A connecting pipe 222 is fixedly installed at the deflation end of the air pump 221. The connecting pipe 222 is connected to the outer sleeve 211 on one side of the elastic band 22. Gas flows into the flow groove 212 through the connecting pipe 222.

[0042] Referring to Figures 2-6, in this embodiment: each outer sleeve 211 is also provided with multiple sets of vent holes 2121. The vent holes 2121 are connected to the flow channel 212. After the gas flows into the flow channel 212 through the connecting pipe 222, a part of the gas is filled into the air-filled interlayer formed by the outer sleeve 211 and the inner sleeve 2111 through the vent holes 2121. As shown in Figure 4, when the air-filled interlayer is filled with gas, the inner sleeve 2111 is squeezed from its original conical state into a pleated ring state that is tightly attached to the heating pipe 1.

[0043] Referring to Figures 2-6, in this embodiment: each outer sleeve 211 is also provided with a second flow groove 213 at the upper part of its interior. The second flow groove 213 is connected to the first flow groove 212, and the outer sleeves 211 of two adjacent insulation units are connected through the second flow groove 213.

[0044] Referring to Figures 2-6, in this embodiment: each set of insulation units has aerogel powder pre-placed in the air-filled interlayer. The powder is evenly distributed in the interlayer and is suspended and diffused during the inflation process, forming an aerogel aerosol composite insulation layer in conjunction with static air. As the solid material with the lowest known thermal conductivity, aerogel powder can further reduce the overall thermal conductivity of the air-filled interlayer and greatly enhance the heat conduction barrier effect.

[0045] Meanwhile, the aerogel powder filling the independent air chambers further suppresses the thermal motion of air molecules, forming a double anti-convective barrier with the independent air chamber structure, avoiding airflow disturbances caused by temperature gradients. This design enables the insulation garment body 21 to achieve lightweighting while reducing heat loss by more than 50% compared to traditional single-air-layer insulation structures. Furthermore, the aerogel powder has stable chemical properties and a wide temperature resistance range, maintaining its insulation performance over a long period. After the insulation component 2 is installed on the heating pipe 1, the air pump 221, which has both inflation and deflation functions, is activated, and the gas... The gas is quickly introduced into the flow channel 212 of the first insulation unit via the connecting pipe 222. Then, through the vent holes 2121 and flow channel 213 built into each outer sleeve 211, the gas path of multiple series-connected insulation units is fully connected, allowing the gas to be evenly distributed to the inflatable interlayer formed by each outer sleeve 211 and inner sleeve 2111. As the gas continues to fill, the pressure inside the inflatable interlayer gradually rises to the preset value. The inner sleeve 2111, thanks to the excellent elasticity and shape memory properties of the high-resilience liquid silicone composite spandex fabric, initially adheres to the airflow. The outer conical inner wall is uniformly compressed, ultimately forming a tightly wrapped, pleated ring structure that completely covers the outer wall of the heating pipe 1, achieving a zero-gap fit and completely blocking the air convection channel between the pipe and the outside. Simultaneously, the aerogel powder pre-placed within the air-filled interlayer is suspended and diffused with the airflow, working in conjunction with static air to form an aerogel aerosol composite insulation layer. Combined with the high reflectivity of the outer 211 double-sided TPU-coated aramid composite aluminized fabric, a highly efficient insulation system is constructed that integrates heat radiation reflection, heat conduction blocking, and heat convection inhibition, ensuring the heating pipe 1... The heat loss is reduced by more than 55% compared with traditional insulation structures, and the temperature of the outer surface of the pipe is stably controlled below 45℃. In addition, the tightly fitted inner sleeve 2111 can also isolate external moisture and dust, avoiding condensation and corrosion on the outer wall of the pipe. The sealing structure of the air-filled jacket, together with the rapid exhaust function of the air pump 221, allows for one-button pressure release during subsequent maintenance, and the inner sleeve automatically retracts and resets, making it easy to disassemble and replace the damaged insulation unit. This not only ensures the long-term stable operation of the heating system, but also significantly reduces the operation and maintenance costs and operational difficulty.

[0046] Referring to Figures 2-8, in this embodiment: a connecting pipe 214 is connected to the outer side of the outer sleeve 211 adjacent to the second elastic band 23, and a one-way valve 2141 is installed on the connecting pipe 214; a connecting pipe 215 is connected to the outer side of the outer sleeve 211 adjacent to the third elastic band 24, and a one-way valve 2151 is installed on the connecting pipe 215; one end of the connecting pipe 214 and the connecting pipe 215 are threaded together. To achieve overall connection and uniform inflation of the multiple sets of insulation unit air-filled interlayers, the connecting pipes 214 and 215 serve as air passage connection components, with one end... Each end of the connector corresponds to an end interface fitted to an adjacent insulation unit. The other end of each connector is sealed and connected to the flow channel 212 inside the outer sleeve 211 to which it is connected. This connection design allows airflow to be quickly introduced into the flow channel 212 through the connecting pipe 214 and the connecting pipe 215, and then evenly distributed to the independent air chambers of the corresponding insulation unit by the flow channel 212. At the same time, it ensures that the air paths of multiple series-connected units form a complete through loop, which not only ensures the high efficiency of the inflation process and the uniformity of airflow distribution, but also prevents gas leakage through the sealed connection structure, thus forming a stable static thermal insulation space for the inflation interlayer. Providing support, the precise connection between connecting pipe 214 and connecting pipe 315 enables mechanical fixation and air passage between adjacent sets of insulation units, allowing the air-filled interlayer of multiple units to form a complete connected chamber. Combined with the sealed connection between these two pipes and the internal flow groove 212 of the outer sleeve 211, this ensures that the airflow delivered by the air pump 221 can be quickly and evenly distributed to the independent air chambers of all units, guaranteeing consistent overall inflation pressure and preventing uneven local insulation effects. Simultaneously, one-way valve 2141 and one-way valve 2151 provide bidirectional leak protection; if any set of insulation units is damaged, replacement is required. When replacing, simply unscrew the corresponding connecting pipe 214 and connecting pipe 215. The one-way valve will automatically close and block the air passage of the adjacent unit's inflation interlayer, preventing gas leakage from other intact units. There is no need to depressurize the entire insulation garment, greatly simplifying the replacement operation. The threaded connection method combines connection reliability with easy disassembly, ensuring sealing performance when the air passage is open, preventing gas leakage during inflation, and quickly separating damaged units from intact units, enabling individual replacement of locally damaged parts without affecting the continuous operation of the overall insulation system, significantly improving maintenance efficiency and reducing consumable costs.

[0047] Referring to Figures 7-10, in this embodiment: multiple sets of engaging parts 231 are fixedly installed on the outer side of the elastic band 23, and a buckle 241 matching the engaging parts 231 is fixedly installed on the outer side of the elastic band 24.

[0048] Referring to Figures 7-10, in this embodiment: the locking member 231 is fixedly connected to the elastic band 23. The inner side of the locking member 231 is provided with a locking groove 2311. The inside of the locking groove 2311 is provided with a limiting groove 2312. The inside of the limiting groove 2312 is provided with multiple sets of round holes 2313.

[0049] Referring to Figure 7-12, in this embodiment: a limiting plate 2314 is rotatably installed inside the limiting groove 2312. Torsion springs 2315 are fixedly installed on both sides of the limiting plate 2314. One end of the torsion spring 2315 is fixedly installed inside the limiting groove 2312. A reset rod 2316 is fixedly installed on one end of the limiting plate 2314. Multiple sets of limiting rods 2317 are rotatably installed on the lower end of the limiting plate 2314. The limiting rods 2317 match the round hole 2313. The lower end of the limiting rod 2317 passes through the engaging member 231 and is slidably connected to it.

[0050] Referring to Figure 7-12, in this embodiment: a connecting groove 2318 is provided at the position of the limiting rod 2317 corresponding to the elastic band 23. The connecting groove 2318 is slidably connected to the limiting rod 2317. A connecting groove 232 is also provided inside the elastic band 23. The connecting groove 232 is connected to the connecting groove 2318. The connecting groove 232 is also connected to the flow groove 213.

[0051] Referring to Figure 7-12, in this embodiment: a snap-fit ​​plate 2411 is installed on one side of the snap-fit ​​component 241. The snap-fit ​​plate 2411 matches the snap-fit ​​groove 2311. A limiting groove 2412 is provided at the lower end of the snap-fit ​​plate 2411. The limiting groove 2412 matches the limiting plate 2314. When connecting two sets of insulation units, the snap-fit ​​plate 2411 only needs to be inserted into the snap-fit ​​groove 2311 by hand. In the initial state, the limiting plate 2314 is tilted up under the action of the torsion spring 2315. During the insertion process, the snap-fit ​​plate 2411 squeezes the limiting plate 2314, causing it to overcome the torsion spring force and rotate, and accurately snap into the limiting groove 2412, realizing the rapid mechanical fixation of the two sets of units. No tools are required, and the operation is convenient and efficient. After all the snap-fit ​​components 231 and snap-fit ​​components 241 have been connected, the connection is established. The air pump 221 inflates the gas. When the pressure inside the inflated interlayer reaches the preset value, some of the gas flows into the connecting groove 232 through the second flow channel 232, and then flows into the first connecting groove 2318, generating an upward stable squeezing force on the limiting rod 2317. This causes the limiting rod 2317 to squeeze and limit the limiting plate 2314, avoiding the problem of the limiting plate 2314 falling off and the unit disconnection caused by vibration and collision in simple mechanical connections. If disassembly is required, the limiting plate 2314 can be pried down by the reset rod 2316 to release the locking of the buckle plate 2411. Combined with the threaded disassembly of the connecting pipe 214 and the connecting pipe 3 215, the unit can be quickly separated, perfectly balancing connection reliability and maintenance convenience, and ensuring the structural stability and sealing performance of the overall insulation system.

[0052] Working principle: The insulation component 2 is fitted onto the outside of the heating pipe 1. The multiple insulation units of the insulation garment body 21 are mechanically connected by the locking parts 231 and fasteners 241 on the elastic band 23 and elastic band 34. The air passage is then sealed and connected through the connecting pipe 214 and connecting pipe 3. After the air pump 221 is started, the gas is introduced into the flow groove 212 of the outer sleeve 211 through the connecting pipe 1 222, and then evenly filled into the air-filled interlayer formed by the outer sleeve 211 and the inner sleeve 2111 through the exhaust hole 2121. At the same time, some gas flows through the flow groove. 213. The flow of the second connecting groove 232 into the first connecting groove 2318 pushes the limiting rod 2317 to form a pneumatic-assisted locking of the locking structure, so that the inner sleeve 2111 is squeezed from the initial state of being attached to the outer sleeve 211 into a pleated ring structure that is tightly attached to the heating pipe 1. Through the dual suppression of heat convection by independent air chamber and aerogel powder, the heat radiation reflection function of the outer sleeve 211, and the zero-gap fit of the inner sleeve 2111 to block heat conduction, and the one-way valve automatically isolates the air path when a local unit is damaged, it can be disassembled and replaced separately, ultimately achieving the synergy of efficient heat preservation and convenient operation and maintenance.
