Description

Technical Field

[0001] This utility model belongs to the field of sealing butterfly valve technology, and particularly relates to an electric metal sealing butterfly valve. Background Technology

[0002] Electric metal-sealed butterfly valves are valves used in industrial pipelines, mainly for regulating or cutting off the flow of media. They are characterized by simple structure, convenient operation, and good sealing performance. Electric metal-sealed butterfly valves are suitable for various industrial fields, such as building materials, metallurgy, mining, power, and chemical industries.

[0003] Currently available electric metal-sealed butterfly valves have the following problems in actual use:

[0004] 1. In actual use, the control switch of a traditional electric metal-sealed butterfly valve is usually either fully sealed or exposed to the outside. When the fully sealed control switch is being repaired, the entire device needs to be disassembled. When the control switch is exposed to the outside, it may be entangled by ribbons or similar items, making it inconvenient to use.

[0005] 2. Most electric metal-sealed butterfly valves are unstable during use because their surfaces are mostly curved. When stored, they may shake or roll when impacted, resulting in poor stability. Utility Model Content

[0028] To better understand the purpose, structure, and function of this utility model, the electric metal-sealed butterfly valve of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] like Figure 1-5As shown, this utility model discloses an electric metal-sealed butterfly valve, comprising a butterfly valve body 1, a valve stem device 3 mounted on the surface of the butterfly valve body 1, an electric control device 2 connected to the surface of the valve stem device 3, a fixing block 11 welded to the surface of the electric control device 2, a bushing 12 welded to the surface of the fixing block 11, an external threaded rod 13 sleeved inside the bushing 12, a fixing seat 14 welded to the surface of the external threaded rod 13, and a protective cover 17 welded to the surface of the fixing seat 14. By installing the protective cover 17, when it is necessary to repair the valve stem device 3 during use of the device, the protective cover 17 can be rotated with the external threaded rod 13 in the center until the valve stem device 3 is exposed to the outside, which makes it easier to repair the valve stem device 3. When the valve stem device 3 is inspected, the protective cover 17 is rotated back to its original position to hide the valve stem device 3, thus providing protection for the valve stem device 3. It is very convenient to use. The valve stem device 3 is located inside the protective cover 17. The surface of the external threaded rod 13 is fitted with the extrusion turntable 15. One end of the extrusion turntable 15 is attached to one end of the bushing 12. By installing the extrusion turntable 15, when it is necessary to fix the position of the protective cover 17, the extrusion turntable 15 can be rotated until one end of the extrusion turntable 15 is attached to the sleeve 10. At this time, the friction between the fixing seat 14 and the bushing 12 is increased, thereby fixing the protective cover 17. It is very convenient to use.

[0030] A sleeve 10 is welded to the surface of the butterfly valve body 1. A support plate 4 is provided on the outside of the butterfly valve body 1. A first insert rod 5 is welded to the side of the support plate 4 and is embedded inside the sleeve 10. A spring 7 is welded inside the support plate 4. A second insert rod 6 is welded to the other end of the spring 7 and is embedded inside the sleeve 10. A first retaining ring 8 is welded to the surface of the first insert rod 5 and is attached to one end of the sleeve 10. A second retaining ring 9 is welded to the surface of the second insert rod 6 and is attached to one end of the sleeve 10. By installing the support plate 4, when storing the device, the first insert rod 5 and the second insert rod 6 can be used to rotate the support plate 4. Subsequently, when placing the device, the support plate 4 can be used to support the device, thereby ensuring the stability of the device when placed.

[0031] A magnet 21 is bonded to the surface of the butterfly valve body 1. A groove 22 is formed on the surface of the support plate 4. An iron sheet 23 is bonded inside the groove 22. The magnet 21 is embedded inside the groove 22, and the surface of the magnet 21 is attached to the iron sheet 23. By installing the magnet 21 and the iron sheet 23, when the support plate 4 is not in use, the support plate 4 can be rotated to make the magnet 21 embedded inside the groove 22 until the magnet 21 and the iron sheet 23 are attached. At this time, the support plate 4 can be attracted and fixed by the magnetic attraction effect, which is very convenient to use.

[0032] The butterfly valve body 1 has slots 19 at both ends, and sealing rings 20 are bonded inside the slots 19. The sealing rings 20 are symmetrically distributed. By installing the sealing rings 20, the sealing effect of the device after installation can be improved, and the sealing performance is strong during use.

[0033] A baffle 18 is welded to the surface of the butterfly valve body 1. The baffles 18 are symmetrically distributed and their sides are attached to the surface of the protective cover 17. By installing the baffles 18, the protective cover 17 can be limited, so that the protective cover 17 will not shake when closed, thus improving the stability of the protective cover 17 during use.

[0034] A baffle plate 16 is welded to the other end of the external threaded rod 13. The surface of the baffle plate 16 is attached to the extrusion turntable 15. By installing the baffle plate 16, the extrusion turntable 15 can be limited, so that the extrusion turntable 15 will not detach from the external threaded rod 13, which is very convenient to use.

[0035] The working principle of this electric metal-sealed butterfly valve is as follows: When using this device, it should first be installed in a suitable position. During installation, the sealing ring 20 provides a sealing effect. After installation, it is ready for use. When maintenance of the valve stem device 3 is required during use, the valve stem device 3 is installed on the surface of the butterfly valve body 1, and the electric control device 2 is connected to the surface of the valve stem device 3. A fixing block 11 is welded to the surface of the electric control device 2, and a bushing 12 is welded to the surface of the fixing block 11. Simultaneously, an external threaded rod 13 is fitted inside the bushing 12. A fixing seat 14 is welded to the surface of the external threaded rod 13, and a protective cover 17 is welded to the surface of the fixing seat 14. At this time, the valve stem device 3 is located inside the protective cover 17. A pressing disc 15 is fitted onto the surface of the external threaded rod 13. One end of the pressing disc 15 is attached to one end of the bushing 12. When in use… During the operation of this device, when inspecting the valve stem device 3, the protective cover 17 can be rotated using the external threaded rod 13 at the center until the valve stem device 3 is exposed. This makes it easier to inspect the valve stem device 3. After the inspection is completed, the protective cover 17 can be rotated back to its original position to hide the valve stem device 3, thus providing protection for the valve stem device 3. It is very convenient to use. When storing the device, the second insert rod 6 can be pressed first, at which point the spring 7 will retract. Then, the first insert rod 5 can be inserted into the sleeve 10. After that, the second insert rod 6 can be released, and the second insert rod 6 will be inserted into the sleeve 10 under the action of the spring 7. At this time, the first insert rod 5 and the second insert rod 6 can be used as support plates 4 to rotate. Then, when placing the device, the support plates 4 can be used to support the device, thus ensuring the stability of the device when placed.
