[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, a pipe jacket insulation device with temperature regulation includes a protective shell 1, a thermal insulation layer 2, a heating cable 3, a heat-conducting layer 4, a temperature detection probe and a temperature controller 5. The thermal insulation layer 2 is wrapped around the surface of the pipe, and the protective shell 1 is arranged on the outside of the thermal insulation layer 2; the heat-conducting layer 4 is in contact with the surface of the pipe; the heating cables 3 are arranged between the thermal insulation layer 2 and the heat-conducting layer 4; each heating cable 3 is provided with a connection port 6 extending to the outer surface of the protective shell 1; the heating cable 3 is electrically connected to the temperature controller 5 through the connection port 6, and the temperature detection probe is electrically connected to the temperature controller 5; the insulation device is a split structure, divided into an upper half and a lower half;

[0026] The thermal insulation device adopts a split design and can be mass-produced in sets in the factory and quickly installed on site, shortening the construction period. The basic working method is that the temperature controller 5 detects the ambient temperature of the pipeline through the temperature detection probe, and the temperature controller 5 compares the ambient temperature with the target temperature. When the ambient temperature is lower than the set value, the temperature controller 5 controls the heating cable 3 to start working until the ambient temperature reaches the set temperature, thereby achieving precise temperature control and ensuring the stability of the pipeline temperature.

[0027] A cooperating positioning part is provided between the upper half and the lower half. The positioning part is an easy-to-process shape, such as a stepped shape, a tooth shape, etc., which can ensure that the upper half and the lower half are correctly buckled together, avoid relative displacement between the two, and improve installation efficiency.

[0028] To ensure that the heat-conducting layer 4 can fully fit the pipeline, the thermal insulation layer 2 is made of a material with a certain elasticity (so the actual volume of the thermal insulation layer 2 should be slightly larger than the space between the protective shell 1 and the pipeline), and the upper and lower halves are extruded and assembled, and fixedly connected by a metal lock 7.

[0029] The heat-conducting layer 4 is a mesh structure, specifically a metal mesh cloth. Since the contact area between the heating cable 3 and the pipeline is limited, using a metal mesh cloth with a high thermal conductivity coefficient as a heat-conducting medium can increase the heat conduction area, so that the heat can be quickly and evenly conducted to the pipeline, resulting in a better heating effect.

[0030] The heating cables 3 available on the market include low-temperature universal type, medium-temperature universal type, high-temperature universal type, constant power type, and self-limiting temperature type. In this embodiment, the heating cable 3 uses a self-limiting temperature heating cable. The self-limiting temperature heating cable is composed of nano-conductive carbon particles and two parallel busbars with an insulating layer. Due to this parallel structure, all self-limiting temperature heating cables can be cut to any length on site, making them more flexible to use.

[0031] The conductive polymer of the self-limiting temperature heating cable has a high positive temperature coefficient characteristic, and when connected in parallel, it can automatically adjust the output power as the temperature of the heated system changes, and automatically limit the heating temperature, so it is safer and more reliable to use;

[0032] In this embodiment, the temperature controller 5 adjusts the heating power of the heating cable 3 by adjusting the current flowing through the heating cable 3, thereby achieving precise temperature control; the heating cables 3 located in different upper and lower parts form a suitable series-parallel network through the external reserved connection port 6 and are connected to the temperature controller 5;

[0033] The thermal insulation device is radially divided into several sections for installation, and jumper wires 8 and relay junction boxes 9 are arranged between adjacent sections; the connection ports 6 of two adjacent sections are connected through the jumper wire 8; the jumper wire 8 is arranged in the relay junction box 9, and the function of the relay junction box 9 is mainly to protect the connection port 6, so it is acid- and alkali-resistant, high-temperature-resistant, insulated and sealed; similarly, in order to facilitate connection, a female-female quick-connect connector is used between the connection port 6 and the jumper wire 8.

[0034] The thermal insulation layer 2 can be made of rubber plastic, glass wool, rock wool, mineral wool, polyurethane and other materials, and can be selected according to actual conditions. The thermal insulation layer 2 in this embodiment uses polyurethane foam, which has good thermal insulation performance, waterproof performance, sound insulation effect, cushioning performance, electrical insulation, heat resistance, cold resistance, solvent resistance and other characteristics; the protective shell 1 can be made of stainless steel or aluminum as needed.

[0035] In this embodiment, Figure 2 、 Figure 3 and Figure 4As shown, the protective shell 1, thermal insulation layer 2, heating cable 3, thermal conductive layer 4 and connection port 6 are made into an integrated form and quickly assembled on site, which can greatly shorten the construction period, reduce material waste and will not cause pollution to the site, and is more environmentally friendly; it is easy to assemble and disassemble, and since the installation does not damage the structure and function, it can be reused.

[0036] Example 2

[0037] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, a pipe jacket insulation device with temperature regulation includes a protective shell 1, a thermal insulation layer 2, a heating cable 3, a heat-conducting layer 4, a temperature detection probe and a temperature controller 5. The thermal insulation layer 2 is wrapped around the surface of the pipe, and the protective shell 1 is arranged on the outside of the thermal insulation layer 2; the heat-conducting layer 4 is in contact with the surface of the pipe; the heating cables 3 are arranged between the thermal insulation layer 2 and the heat-conducting layer 4; each heating cable 3 is provided with a connection port 6 extending to the outer surface of the protective shell 1; the heating cable 3 is electrically connected to the temperature controller 5 through the connection port 6, and the temperature detection probe is electrically connected to the temperature controller 5; the insulation device is a split structure, divided into an upper half and a lower half;

[0038] The thermal insulation device adopts a split design and can be mass-produced in sets in the factory and quickly installed on site, shortening the construction period. The basic working method is that the temperature controller 5 detects the ambient temperature of the pipeline through the temperature detection probe, and the temperature controller 5 compares the ambient temperature with the target temperature. When the ambient temperature is lower than the set value, the temperature controller 5 controls the heating cable 3 to start working until the ambient temperature reaches the set temperature, thereby achieving precise temperature control and ensuring the stability of the pipeline temperature.

[0039] A cooperating positioning part is provided between the upper half and the lower half. The positioning part is an easy-to-process shape, such as a stepped shape, a tooth shape, etc., which can ensure that the upper half and the lower half are correctly buckled together, avoid relative displacement between the two, and improve installation efficiency.

[0040] To ensure that the heat-conducting layer 4 can fully fit the pipeline, the thermal insulation layer 2 is made of a material with a certain elasticity (so the actual volume of the thermal insulation layer 2 should be slightly larger than the space between the protective shell 1 and the pipeline), and the upper and lower halves are extruded and assembled, and fixedly connected by a metal lock 7.

[0041] A dustproof and waterproof rubber gasket is provided between the upper protective shell 1 and the lower protective shell 1. During actual installation, the edge of the upper protective shell 1 should slightly exceed the lower protective shell 1 (such as 5-10mm) to prevent dust, sewage and other debris from entering the interior of the insulation device.

[0042] The heat-conducting layer 4 is a mesh structure, specifically a metal mesh cloth. Since the contact area between the heating cable 3 and the pipeline is limited, using a metal mesh cloth with a high thermal conductivity coefficient as a heat-conducting medium can increase the heat conduction area, so that the heat can be quickly and evenly conducted to the pipeline, resulting in a better heating effect.

[0043] The heating cables 3 available on the market include low-temperature universal type, medium-temperature universal type, high-temperature universal type, constant power type, and self-limiting temperature type. In this embodiment, the heating cable 3 uses a self-limiting temperature heating cable. The self-limiting temperature heating cable is composed of nano-conductive carbon particles and two parallel busbars with an insulating layer. Due to this parallel structure, all self-limiting temperature heating cables can be cut to any length on site, making them more flexible to use.

[0044] The conductive polymer of the self-limiting temperature heating cable has a high positive temperature coefficient characteristic, and when connected in parallel, it can automatically adjust the output power as the temperature of the heated system changes, and automatically limit the heating temperature, so it is safer and more reliable to use;

[0045] In this embodiment, the temperature controller 5 adjusts the heating power of the heating cable 3 by adjusting the current flowing through the heating cable 3, thereby achieving precise temperature control; the heating cables 3 located in different upper and lower parts form a suitable series-parallel network through the external reserved connection port 6 and are connected to the temperature controller 5;

[0046] Optionally, the heating cable 3 can be replaced with a cooling device, or a cooling device can be added on the original basis, so that the temperature adjustment range can be increased, which is suitable for pipeline equipment that needs to be insulated in certain environments with large temperature differences.

[0047] The thermal insulation device is radially divided into several sections for installation, and jumper wires 8 and relay junction boxes 9 are arranged between adjacent sections; the connection ports 6 of two adjacent sections are connected through the jumper wire 8; the jumper wire 8 is arranged in the relay junction box 9, and the function of the relay junction box 9 is mainly to protect the connection port 6, so it is acid- and alkali-resistant, high-temperature-resistant, insulated and sealed; similarly, in order to facilitate connection, a female-female quick-connect connector is used between the connection port 6 and the jumper wire 8.

[0048] In order to ensure that adjacent segments can be tightly connected, mutually cooperating joints are provided between the contact surfaces of adjacent segments; the joints are stepped. Furthermore, a protective device can be provided at the joints of two adjacent segments to prevent dust and water.

[0049] The thermal insulation layer 2 can be made of rubber plastic, glass wool, rock wool, mineral wool, polyurethane and other materials, and can be selected according to actual conditions. The thermal insulation layer 2 in this embodiment uses polyurethane foam, which has good thermal insulation performance, waterproof performance, sound insulation effect, cushioning performance, electrical insulation, heat resistance, cold resistance, solvent resistance and other characteristics; the protective shell 1 can be made of stainless steel or aluminum as needed.

[0050] In this embodiment, Figure 2 、 Figure 3 and Figure 4 As shown, the protective shell 1, thermal insulation layer 2, heating cable 3, thermal conductive layer 4 and connection port 6 are made into an integrated form and quickly assembled on site, which can greatly shorten the construction period, reduce material waste and will not cause pollution to the site, and is more environmentally friendly.

[0051] Advantages of the implementation of this utility model:
