[0002] In high-temperature industrial environments, such as petroleum, chemical, and metallurgical fields, butterfly valves in pipeline systems often need to withstand extremely high temperatures. Traditional butterfly valves often suffer from poor heat dissipation under high-temperature conditions, leading to performance degradation, sealing failure, or even damage. Therefore, heat-resistant butterfly valves designed for high-temperature environments are required.

[0003] The prior art patent document CN221120943U provides a butterfly valve for high-temperature environments. It can be applied in high-temperature environments. The valve body adopts a cubic structure for easy upright placement. The valve seat is made of corundum casting material, which has both good heat resistance and good plasticity.

[0004] While the aforementioned existing technologies can provide good heat resistance, the heat-resistant and heat-dissipating measures, such as using high-temperature resistant materials, are still insufficient in high-temperature environments. Butterfly valves mainly rely on natural heat dissipation, which has low heat dissipation efficiency and cannot be used well in high-temperature environments, thus failing to meet people's needs. Therefore, we need a heat-resistant butterfly valve for high-temperature environments. Utility Model Content

[0025] Through the above technical solution, the heat on the butterfly valve body 1 is conducted to the heat dissipation fins 206, increasing the heat dissipation area. When the cooling fan 205 works, it blows air onto the heat dissipation fins 206. Through the synergistic effect of the cooling fan 205 and the heat dissipation fins 206, the heat inside the butterfly valve body 1 can be quickly dissipated to the surrounding environment, keeping the temperature of the butterfly valve body 1 within a controllable range. It has the advantages of high heat dissipation efficiency and can be used in high-temperature environments. When the butterfly valve body 1 is installed with the fixed pipe 4, the sealing effect is enhanced by the setting of the first sealing ring 603 and the second sealing ring 605, which enhances the sealing performance of the butterfly valve in high-temperature environments. The structure is simple and easy to use.

[0026] Specifically, there are two cooling fans 205, and the two cooling fans 205 are symmetrically arranged with the vertical line of the butterfly valve body 1 as the axis of symmetry.

[0027] The above technical solution, by setting two cooling fans 205, can effectively dissipate heat.

[0028] Specifically, there are two dustproof nets 204, and the two dustproof nets 204 are symmetrically arranged on the fan casing 203. This device is connected to an external controller for control and is powered by an external power supply.

[0029] The above technical solution, by setting two dustproof nets 204, can effectively prevent impurities from entering the fan casing 203 and affecting the normal operation of the cooling fan 205.

[0030] Specifically, there are multiple heat dissipation fins 206, and the multiple heat dissipation fins 206 are arranged at equal intervals on the butterfly valve body 1.

[0031] Through the above technical solution, by setting multiple heat dissipation fins 206, the heat inside the butterfly valve body 1 is conducted to the heat dissipation fins 206, thereby increasing the heat dissipation area and improving the heat dissipation efficiency.

[0032] Specifically, the shape and size of the pipe flange 5 match the shape and size of the connecting pipe 601, and one end of the connecting pipe 601 extends into the pipe flange 5 for connection.

[0033] The above technical solution enhances the connection between the pipe flange 5 and the connecting pipe 601, making it easier for the connecting pipe 601 to extend into the pipe flange 5 and making the connection tighter.

[0034] Specifically, the inner wall shape and size of the first sealing groove 602 match the outer wall shape and size of the first sealing ring 603, and the inner wall of the first sealing groove 602 fits against the outer wall of the first sealing ring 603.

[0035] The above technical solution enhances the connection between the first sealing groove 602 and the first sealing ring 603, making it easier for the first sealing ring 603 to better perform its function.

[0036] Specifically, the inner wall shape and size of the second sealing groove 604 match the outer wall shape and size of the second sealing ring 605, and the inner wall of the second sealing groove 604 fits against the outer wall of the second sealing ring 605.

[0037] Through the above technical solution, the connection between the second sealing groove 604 and the second sealing ring 605 is improved, which makes it easier for the second sealing ring 605 to better perform its function.

[0038] When using the butterfly valve, firstly, align the mounting flange 3 on the butterfly valve body 1 with the pipe flange 5 on the fixed pipe 4, and assemble the mounting flange 3 onto the pipe flange 5. Insert the connecting pipe 601 on the mounting flange 3 into the pipe flange 5, and fix the mounting flange 3 and the pipe flange 5 with bolts and nuts. The outer wall of the connecting pipe 601 fits against the inner wall of the pipe flange 5. The first sealing ring 603 set here enhances the sealing effect at the connection. The outer wall of the pipe flange 5 fits tightly against the outer wall of the mounting flange 3. The second sealing ring 605 set here enhances the sealing effect at the connection, improving the sealing performance of the butterfly valve in high-temperature environments. The structure is simple and easy to use. The heat inside the butterfly valve body 1 is conducted to the heat dissipation fins 206. The heat dissipation fan 205 blows air onto the heat dissipation fins 206 to carry away the heat and dissipate it into the surrounding environment, keeping the temperature of the butterfly valve body 1 within a controllable range, improving heat dissipation efficiency, and ensuring that the butterfly valve can be used in high-temperature environments. This completes all the work. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
