Description

Technical Field

[0001] The utility model relates to the technical field of fireproof flanges, in particular to a heat-insulating fireproof flange. Background Art

[0002] In the modern industrial field, especially in the petrochemical, energy, and metallurgical industries, safety is a crucial consideration. Any fire or explosion accident may cause serious casualties, property losses, and environmental damage. Therefore, the fireproof performance requirements for key equipment and connecting components are becoming increasingly strict. Traditional flanges are prone to heat conduction, resulting in an increase in the temperature of the connecting part, which not only affects the normal operation of the equipment but also may pose a fire risk.

[0003] Flanges are widely used to connect various pipelines, containers, and equipment. In a refinery, from the input of crude oil to the output of various refined products, a large number of pipelines are required for transportation, and flanges are the key components connecting these pipelines. Therefore, flanges need to have good sealing performance, corrosion resistance, and high-temperature and high-pressure resistance. In the water supply and drainage project, flanges are mainly used to connect various pipelines and valves. Whether it is a city water supply pipeline or a sewage treatment pipeline, flanges are required for connection and installation.

[0004] The origin of flanges can be traced back to ancient pipeline connection technologies. With the development of metal processing technologies, metal flanges gradually emerged, but their structures were relatively simple. When a fire occurred, traditional flanges often could not effectively prevent the spread of flames. Metal flanges may lose strength at high temperatures, resulting in the rupture of the connecting part and further expansion of the fire. Moreover, the sealing materials of traditional flanges are prone to combustion in a fire, exacerbating the harm of the fire. In the connecting pipelines of some high-temperature industrial furnaces, traditional flanges can increase the surface temperature of the pipelines, not only wasting energy but also posing potential safety hazards to the surrounding staff and equipment.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to the attached Figure 1 , attached Figure 2 and attached Figure 3 , an embodiment provided by the present invention: a heat insulation and fireproof flange, including a ceramic tube 1.

The upper and lower sides of the ceramic tube 1 are fixedly connected with a heat insulation mechanism 2. The heat insulation mechanism 2 is used for heat insulation treatment of the flange;

[0033] Specifically, the sliding shaft 1 at the lower side inside the ceramic tube 1 is fixedly connected, which not only serves as a structural support but also is ingeniously connected to the spring 6. The other end of the spring 6 is fixedly connected to the sliding shaft 2 11. This spring 6 connection mechanism endows the connecting tube 9 with a certain floating ability, which can buffer the thermal stress caused by temperature changes to a certain extent, protect the equipment from damage, and the elasticity of the spring 6 also ensures the stable operation of the connecting tube 9 under complex working conditions. As one of the core components, both ends of the outer wall of the connecting tube 9 are rotatably connected to the rotating shafts 7, and these rotating shafts 7 are tightly connected to the connecting plate 2 8 through the fixed shafts 10. This multi-axis connection design not only enhances the structural stability but also enables the connecting tube 9 to flexibly adjust its position in multiple directions to adapt to different installation and usage requirements. Heat insulation mechanisms 2 are fixedly connected to both the upper and lower sides of the ceramic tube 1. These heat insulation mechanisms 2 adopt advanced heat insulation materials and technologies, which can effectively block the transfer of heat.

Multiple heat insulation holes 206 are opened on the outer wall of the fireproof circular plate 204. Multiple heat insulation holes 206 are opened at the upper and lower ends of the outer wall of the fireproof column 207. Multiple heat insulation holes 205 are opened at the upper and lower ends of the outer wall of the fireproof column 207.

Inside the fireproof column 207, there is a key component, the heat insulation shaft 201. The heat insulation shaft 201 is firmly fixed inside the fireproof column 207 through precise welding or bolt connection technology. Around the heat insulation shaft 201, there are multiple heat insulation plates 202. These heat insulation plates 202 not only have excellent materials and can effectively isolate high temperature. In the middle of the outer wall of the fireproof column 207, there is a fixed connection with a fireproof circular plate 204. This design not only enhances the structural stability but also further improves the heat insulation performance through multiple heat insulation holes two 206 opened on its outer wall.

[0036] Please refer to the appendix Figure 2 - appendix Figure 5 On the upper part of the outer wall of the fireproof column 207, there is a fixed connection with a heat insulation strip two 17. Around the upper part of the outer wall of the fireproof column 207, there are fixed connections with protection plates one 13 on all sides. In the middle of the outer walls of multiple fireproof columns 207, there are fixed connections with heat insulation holes two 206.

At the other end of the fixing plate one 14, there is a fixing hole 19;

[0037] Specifically, around the upper part of the outer wall of the fire column 207, there is a sturdy protective plate 13 tightly attached to it. These protective plates not only enhance the overall strength of the fire column 207, but also, during a fire, can resist the direct impact of the flames and slow down the spread of the fire. There are multiple heat insulation holes 206 on the outer wall of the middle part of the fire column 207. These heat insulation holes not only help regulate the temperature inside the building, but also effectively isolate the heat intrusion from external fire sources through their unique design. The lower end of the fire column 207 is firmly fixedly connected to the protective plate 23. The existence of this protective plate provides a stable support for the fire column 207. There is also a protective plate 15 fixedly connected to the top of the outer wall of the fire column 207, and the fixing plate 14 is also ingeniously fixedly connected to the outer wall of the protective plate 13. These fixing plates not only enhance the stability of the protective plate, but also, through the fixing holes 19 opened at the other ends, facilitate the connection of the fire column 207 with other building components.

[0038] Working principle: When the inner wall or the outer wall is heated, the sliding shaft 1 of the inner elastic mechanism slides, and the telescopic movement drives the sliding shaft 2 and the sliding shaft 1 to move outward. The device's sliding shaft 2 and sliding shaft 1 respectively drive the connecting plate 1 to move. The inner walls of the device's connecting plate 1 are all connected to the fixed shaft 10. The device's fixed shaft 10 is fixed on the outer wall of the rotating shaft 7. The device's rotating shaft 7 rotates and is slidably connected to the outer wall of the connecting pipe 9. At the same time, a ceramic pipe 1 is installed on the outer wall of this mechanism. The device's ceramic pipe 1 can protect against external flames and also dissipate heat well inside. Therefore, in environments such as high-temperature steam pipelines, this flange can effectively insulate heat. The heat will be transferred to the surrounding environment through the flange. At the same time, the elastic mechanism can well increase the stress of the device, greatly improving the working efficiency and making it safer to use.

[0039] Heat insulation devices are installed on the upper and lower parts of this flange. The heat insulation shaft 201 is installed inside the fire column 207. This device is composed of multiple heat insulation plates 202. Multiple strip-shaped holes 203 are opened between the device's heat insulation plates 202, thus forming a maze-like heat dissipation path to achieve a good heat insulation effect. Heat insulation holes 205 and heat insulation holes 206 are also opened on the outer wall of the fire column 207 to conduct heat outward, combining the heat insulation layer and the fire protection layer to form an overall protection system. The heat insulation and fire protection flange adopts a labyrinth seal structure, increasing the flow resistance of flames and high-temperature gases and improving the fire protection performance to ensure good performance under high-temperature and fire conditions.
