The opening and closing element of a butterfly valve is a disc, also called a valve flap or butterfly plate, which rotates around the valve shaft. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, and oil. An electric butterfly valve is a valve device consisting of an electric actuator and a butterfly valve, and it plays an important role in the field of industrial automation control.
[0003] If a high-temperature fluid continuously flows through an electric butterfly valve during use, the heat from the butterfly valve will be continuously transferred to the electric actuator after prolonged use, which may cause the electric actuator to overheat and be damaged. Therefore, a high-temperature resistant butterfly valve is proposed to address the above problem. Summary of the Invention

[0026] Please refer to Figures 1-6. This utility model provides a technical solution:
[0027] A high-temperature resistant butterfly valve includes a butterfly valve body 1, a connecting pin 2 mounted on the top of the butterfly valve body 1, an electric actuator 3 mounted on the outside of the connecting pin 2, and a mounting base 4 mounted on the inner side of the bottom of the electric actuator 3. A cooling ring 5 is provided on the outside of the connecting pin 2. The upper and lower ends of the cooling ring 5 are fixedly connected to symmetrically arranged sealing rings 6. Multiple heat-conducting plates 7 are fixedly connected inside the cooling ring 5. Multiple through holes 8 are formed inside the heat-conducting plates 7. Multiple heat dissipation plates 9 are fixedly connected to the outside of the cooling ring 5. The heat dissipation plates 9 are symmetrically arranged and fixedly connected to the cooling ring. The first pagoda connector 10, which is located on the outer side of the ring 5 and penetrates the cooling ring 5, has multiple vertically arranged through slots 11 on the inner side of the cooling ring 5. Below the through slots 11, there is a sliding groove 12 located in the center of the inner side of the cooling ring 5. A heat-conducting component 13 is provided on the inner side of the sliding groove 12. A connecting pin 2 is inserted into the inner side of the mounting base 4. The butterfly valve body 1 and the electric actuator 3 are fixedly connected by bolts and nuts. The outer side of the upper sealing ring 6 is tightly fitted with the bottom end of the electric actuator 3, and the outer side of the lower sealing ring 6 is tightly fitted with the top end of the butterfly valve body 1. The heat-conducting component 13 includes components located on the cooling ring 5. The inner side of the cooling ring 5 has a heat-conducting block 131. A slot 132 is vertically pierced through the heat-conducting block 131. Multiple ball bearings 133, arranged in a polar axis distribution, are rolled on the outer side of the heat-conducting block 131. The number of ball bearings 133 is the same as the through groove 11, and the diameter of the through groove 11 is larger than the diameter of the ball bearings 133. The ball bearings 133 are located inside the sliding groove 12. A connecting pin 2 is inserted into the inner side of the slot 132. The inner side of the cooling ring 5 and the outer side of the heat-conducting block 131 are in close contact. The cooling ring 5, sealing ring 6, heat-conducting plate 7, through hole 8, heat dissipation plate 9, and other components are connected. The butterfly valve body 1 has a pagoda connector 10, a through groove 11, a sliding groove 12, and a heat-conducting component 13. When a high-temperature medium passes through the butterfly valve body 1, the condensing medium passes through the through hole 8 on the heat-conducting plate 7, thereby carrying away the heat in the cooling ring 5. When the electric actuator 3 is started, the mounting base 4 drives the connecting pin 2 to rotate. At this time, the heat-conducting block 131 rotates with the connecting pin 2, and the ball 133 rolls on the inner side of the sliding block. This design can effectively prevent the heat in the butterfly valve body 1 from being transferred to the electric actuator 3. Moreover, this design does not change the original structure of the device and does not affect the normal operation of the device.
[0028] A condensing jacket 14 is provided on the outside of the butterfly valve body 1. A symmetrically arranged connecting plate 15 is welded to the top of the condensing jacket 14. A second pagoda connector 16 is symmetrically arranged on the outside of the condensing jacket 14 and passes through the condensing jacket 14. The condensing jacket 14 is located in the center of the outside of the butterfly valve body 1 and fits tightly against the outside of the butterfly valve body 1. The second pagoda connector 16 is located at the top of the outside of the condensing jacket 14. Through the condensing jacket 14, the connecting plate 15 and the second pagoda connector 16, when the high temperature medium passes through the butterfly valve body 1, the condensing medium can enter the condensing jacket 14 at the bottom of the connecting plate 15, thereby reducing the heat of the sealing gasket in the butterfly valve body 1 and preventing the sealing gasket from deforming due to high temperature.
[0029] Workflow: Before use, install all components on the equipment. First, install the heat-conducting component 13, placing it above the cooling ring 5 so that the ball bearing 133 is vertically aligned with the through groove 11. Then, move the heat-conducting component 13 downwards, causing the ball bearing 133 to roll inside the through groove 11 until it moves to the inside of the slide groove 12. At this point, the ball bearing 133 can slide inside the slide groove 12. Next, place the cooling ring 5 outside the connecting pin 2 on the butterfly valve body 1, inserting the connecting pin 2 into the slot 132. Then, place the electric actuator 3 on the butterfly valve body 1. At the top, insert the connecting pin 2 into the inner side of the mounting base 4, and use bolts and nuts to fix the electric actuator 3, ensuring that the outer side of the upper sealing ring 6 is tightly fitted with the bottom end of the electric actuator 3, and the outer side of the lower sealing ring 6 is tightly fitted with the top end of the butterfly valve body 1. This completes the installation of the cooling ring 5 and the heat conduction component 13. Next, fit the condensing jacket 14 onto the center of the outer side of the butterfly valve body 1, and weld the connecting plate 15 to the top of the condensing jacket 14, thus completing the installation of each component of the device. The next step is to install the butterfly valve body 1 between the two pipes. When there is a slightly higher... When the medium passes through the butterfly valve body 1, the temperature is transferred to the cooling ring 5 through the connecting pin 2. The temperature in the cooling ring 5 is transferred to the heat dissipation plate 9 through the heat conduction plate 7 and dissipated through the heat dissipation plate 9. If it is necessary to transport high-temperature medium, the first pagoda connector 10 and the second pagoda connector 16 are connected to an external condenser circulator, and the condenser circulator is started. When high-temperature medium passes through the butterfly valve body 1, the temperature is transferred to the cooling ring 5 through the connecting pin 2 and the heat conduction block 131. The condensing medium passes through the through hole 8 on the heat conduction plate 7, thereby carrying away the heat in the cooling ring 5. When the electric actuator 3 is started... The mounting base 4 drives the connecting pin 2 to rotate. At this time, the heat-conducting block 131 rotates with the connecting pin 2, and the ball 133 rolls on the inner side of the sliding block. This design can effectively prevent the heat in the butterfly valve body 1 from being transferred to the electric actuator 3, thereby preventing the electric actuator 3 from overheating and being damaged. Moreover, this design will not change the original structure of the device and will not affect the normal operation of the device. When the high-temperature medium passes through the butterfly valve body 1, the condensing medium can enter the condensing jacket 14 at the bottom of the connecting plate 15, thereby reducing the heat of the sealing gasket in the butterfly valve body 1 and preventing the sealing gasket from deforming due to high temperature.
