Description

Technical Field

[0001] The utility model relates to the technical field of pipeline thermal insulation, in particular to a heating and ventilation pipeline thermal insulation device. Background Art

[0002] In various building environments and industrial scenarios, the reasonable regulation of indoor and outdoor temperatures is of great significance. People expect to be warm in winter and cool in summer, and temperature regulation is to create a comfortable space by heating and cooling with HVAC equipment. In this comfortable environment, people can carry out various activities more efficiently. However, when the temperature is adjusted through pipeline transportation, due to the temperature difference between the inside and outside of the pipeline, the temperature transportation will suffer a great loss due to heat transfer, resulting in a waste of resources. Therefore, an insulation device is needed to protect the hot and cold air during the transportation process, thereby reducing the energy consumption when the equipment is in use. While achieving energy conservation and emission reduction, it also further improves the operating quality and economy of the entire HVAC equipment.

[0003] The existing thermal insulation device is mainly composed of a thermal insulation material layer, a protective outer layer and fixing components. The thermal insulation effect is achieved by cutting the thermal insulation material according to the length of the pipeline to wrap the pipeline, and then fixing the protective outer layer in the wrapped position by the fixing components. However, the connection between the components of the existing thermal insulation device is sealed by gluing. This sealing method is prone to aging and failure of the glue under long-term use and large temperature changes, resulting in insufficient sealing, thereby reducing the thermal insulation effect and affecting the service life of the equipment. In addition, the fixing method is fixed by simple screws and nuts, and the fixing effect is poor and easy to loosen. Disassembly and maintenance in the event of a fault and installation after maintenance are also relatively complicated, which is difficult to meet usage requirements. Utility Model Content

[0030] 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.

[0031] Please see the attached Figure 1 , Attachment Figure 2 and attached Figure 3 The utility model provides an embodiment of a heating pipe insulation device, comprising a lower pipe sleeve 1, a plurality of slide grooves 3 are opened on the front and rear sides of the top of the lower pipe sleeve 1, a stopper 4 is fixedly connected to the top of the left side of the slide groove 3, a slide bar 5 is slidably connected to the inner wall of the slide groove 3, and the top of the slide bar 5 is fixedly connected to the upper pipe sleeve 6. The slide groove 3 provides flexibility for the structure and also provides convenience for installation. The function of the stopper 4 is to prevent the slide bar 5 from accidentally sliding out during use. The slide bar 5 can slide freely in the slide groove 3, thereby realizing the relative movement between the pipe sleeves. The inner walls of the pipe sleeve 1 and the upper pipe sleeve 6 are provided with multiple flexible insulation pads 7, a locking hole 8 is opened on the right side of the slide bar 5, the inner wall of the locking hole 8 is slidably connected with a locking column 10, the right side of the locking column 10 is fixedly connected with a locking block 9, the inner wall of the locking block 9 is threadedly connected with a screw 11, after the slide bar 5 slides to the appropriate position, it can be fixed by the locking block 9 and the screw 11, so as to ensure the stability during use after fixation, and the left and right sides of the lower pipe sleeve 1 are provided with sealing mechanisms 2, which are used to seal and improve the thermal insulation effect.

[0032] Please see the attached Figure 1 , Attachment Figure 4 and attached Figure 5 The sealing mechanism 2 includes a conveying pipe 201. The outer wall of the conveying pipe 201 is arranged on the inner wall of the flexible thermal insulation pad 7. A plurality of sealing rings 202 are fixedly connected to the left and right edges of the outer wall of the conveying pipe 201. The conveying pipe 201 is used to convey media of different temperatures and is connected to the flexible thermal insulation pad 7 to ensure the stability and thermal insulation effect of the conveying pipe 201 and improve the overall sealing performance. The sealing ring 202 effectively prevents energy loss. The left and right sides of the conveying pipe 201 are fixedly connected with sealing rings 20 3. A sealing groove 204 is provided on the left side of the right sealing ring 202. A plurality of sealing sleeves 205 are fixedly connected to the left and right sides of the flexible thermal insulation pad 7. An extrusion sheet 206 is fixedly connected to the inner wall of the sealing sleeve 205. A gradually widened surface 207 is provided at the bottom of the extrusion sheet 206. When the extrusion sheet 206 provides pressure, it can better fit the inner wall of the sealing sleeve 205, thereby improving the sealing effect. The gradually widened surface 207 increases the contact area of ​​the seal, making the extrusion sheet 206 more stable during operation and ensuring the sealing of the fluid.

[0033] Please see the attached Figure 1 The top of the outer wall of the upper pipe sleeve 6 is fixedly connected with multiple protective sleeves 12, and the bottom of the outer wall of the lower pipe sleeve 1 is fixedly connected with multiple protective sleeves 2 13. The protective sleeve 12 provides additional protection for the upper pipe sleeve 6 to ensure that it will not be damaged by external factors during use. The protective sleeve 2 13 plays a role in protecting the lower pipe sleeve 1 to prevent it from unnecessary damage during use. Multiple support blocks 14 are fixedly connected to the left and right sides of the bottom of the lower pipe sleeve 1. The bottom of the support block 14 is fixedly connected to a support frame 15, and the bottom of the support frame 15 is fixedly connected to a reinforcement block 16. The support frame 15 increases the overall stability and disperses the pressure borne by the lower pipe sleeve 1, thereby extending its service life. The reinforcement block 16 provides additional supporting force to ensure that the entire structure can remain stable when subjected to a large load. The bottom of the reinforcement block 16 is fixedly connected to a bottom plate 17.

[0034] Please see the attached Figure 1 A card slot 18 is provided in the middle of the top of the bottom plate 17, and a nameplate 19 is fixedly connected to the inner wall of the card slot 18. The inner wall of the card slot 18 has been precisely processed to ensure that it can firmly fix the nameplate 19, thereby providing clear identification information. The right top of the lower pipe sleeve 1 is threadedly connected to the left side of the outer wall of the screw 11. The protective sleeve 1 12 and the protective sleeve 2 13 are arranged symmetrically. The extrusion piece 206 is slidably connected to the inner wall of the sealing groove 204. The extrusion piece 206 is an arc-shaped strip. The protective sleeve 1 12 and the protective sleeve 2 13 are arranged symmetrically to provide a uniform protection effect. The extrusion piece 206 is an arc-shaped strip so as to achieve a smooth sliding connection with the inner wall of the sealing groove 204, ensuring a sealing effect and facilitating operation and maintenance.

[0035] Working principle: by opening the slide groove 3 on the lower pipe sleeve 1, the upper pipe sleeve 6 can be better positioned and docked with it through the slide bar 5, the slide bar 5 is docked against the right side of the slide groove 3, and then the connection point on the left side of the slide bar 5 is inserted into the groove formed by the stop block 4 and the slide groove 3. Since the flexible insulation pad 7 is arranged inside the two pipe sleeves, the two can achieve insulation effect after splicing. After splicing, it is only necessary to insert the locking column 10 on the locking block 9 into the locking hole 8 opened on the right side of the slide bar 5, and then thread the screw 11 with the locking block 9. By screwing the screw 11 into the threaded groove of the lower pipe sleeve 1, the locking column 10 locks the slide bar 5 and the locking block 9 squeezes the slide bar 5. This structure locks layer by layer, improves the stability of the fixation, and makes installation and disassembly more accurate and quick, meeting the fixing effect.

[0036] A sealing ring 1 202 is provided at the sealing positions at both ends of the conveying pipe 201, and a sealing ring 203 is provided next to the sealing ring 1 202, so that a sealing groove 204 is formed between the sealing ring 1 202 and the sealing ring 2 203. When the lower pipe sleeve 1 and the upper pipe sleeve 6 are spliced, the sealing sleeves 205 provided on the two sleeves will be docked and extruded together. Since an extrusion sheet 206 is also provided on the sealing sleeve 205, the extrusion sheet 206 will be squeezed into the interior of the sealing groove 204 through the gradually widened surface 207 provided at the sealing end, thereby improving the sealing performance of the multi-layer sealing component through extrusion. Such a structure is simple, but improves the sealing effect well, reduces the production cost, and meets the sealing requirements.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
