Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to an electric butterfly valve with a protective device. Background Technology

[0002] With the continuous improvement of industrial automation, valves, as crucial control components in pipeline systems, are widely used in various industrial fields such as petroleum, chemical, power, metallurgy, and water treatment. Electric butterfly valves, due to their simple structure, rapid opening and closing, small size, light weight, and convenient operation, have become common fluid control devices. They are mainly used to regulate and control parameters such as flow rate, pressure, and temperature of fluids within pipelines.

[0003] For example, Chinese patent CN202122583590.3 discloses an electric butterfly valve. By setting a water level sensor inside the valve disc, when a leak occurs on the surface of the valve disc, water will flow into the valve disc. The water level sensor detects the change in water level and sends a signal to the alarm, causing the alarm to ring and remind the user.

[0004] However, during long-term operation, the electric butterfly valve is prone to some sudden external or internal factors, such as fluctuations in fluid medium pressure or external collisions, which can lead to equipment failure or malfunction, resulting in decreased sealing performance, inflexible operation, or even jamming.

[0005] Based on this, the present invention designs an electric butterfly valve with a protective device to solve the above problems. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] Embodiment 1

[0025] Please refer to Figure 1 - Figure 3 It is illustrated that the electric butterfly valve with the protection device includes a valve body 1, the top of the valve body 1 is fixedly connected with a connecting pipe 2, the top of the connecting pipe 2 is fixedly connected with a connecting plate 3, the top of the connecting plate 3 is fixedly connected with a protection bottom plate 4, the top of the protection bottom plate 4 is fixedly connected with a protection frame 5 at the center position, the inside of the protection frame 5 is fixedly installed with a driving part 6, the inner wall of the channel of the valve body 1 is fixedly connected with a channel pipe 7, the inner wall of the channel pipe 7 is fixedly connected with a valve plate 8, the middle of the valve plate 8 is fixedly connected with a transmission shaft 9, the top of the transmission shaft 9 penetrates the top of the valve body 1 and is fixedly connected in the connecting pipe 2.

[0026] Please refer to Figure 3 And Figure 4 The driving part 6 in the drawing is an electric driving part 6 with a motor or a cylinder as a driving source, and the output end of the driving part 6 is fixedly connected with the top end of the transmission shaft 9.

[0027] In this embodiment, the protective frame 5 is arranged above the protective bottom plate 4, which can effectively protect the driving member 6 from external interference, thereby improving the stability and service life of the electric butterfly valve. The protective frame 5 forms a rigid protection space around the driving member 6 for ventilation, ensuring the safe operation of the driving member 6. The channel pipe 7 is arranged at the inner wall of the passage of the valve body 1, so that the fluid passing through does not directly impact the driving member 6, thereby protecting the normal operation of the driving member 6. The electric butterfly valve not only has good protection performance, but also ensures the normal operation of the valve and the convenience of maintenance.

[0028] It should be noted that the protective frame 5 is used to protect the driving member 6 to a certain extent. The driving member 6 uses a motor or a pneumatic cylinder as a power source, and the output end is fixedly connected with the top end of the transmission shaft 9, which ensures the stability and reliability of the transmission. The top of the transmission shaft 9 penetrates the top of the valve body 1 and is rotatably connected in the connecting pipe 2, so that the driving system of the entire electric butterfly valve is more compact, reducing the space occupation, and facilitating the maintenance and replacement of the transmission parts.

[0029] Example 2

[0030] Please refer to Figure 3 and Figure 6 Example 2 is described. In this embodiment, the protective frame 5 includes a protective upright plate 501, a protective rod 502, and a top plate 503. The protective upright plate 501 is fixedly connected to the top of the protective bottom plate 4. A plurality of protective rods 502 are fixedly connected to the left and right sides of the protective upright plate 501 at equal intervals. The top plate 503 is fixedly connected to the end of the protective rod 502 away from the protective upright plate 501.

[0031] Further, the driving member 6 is fixedly installed inside the protective upright plate 501. The two top plates 503 abut against the front and rear ends of the driving member 6, respectively.

[0032] In this embodiment, the protective frame 5 is composed of the protective upright plate 501, the protective rod 502, and the top plate 503. The protective upright plate 501 is fixed on the protective bottom plate 4. The protective rods 502 are evenly distributed on the two sides of the protective upright plate 501. The top plate 503 is fixed at the distal end of the protective rod 502. The arrangement of the protective upright plate 501 and the protective rod 502 not only enhances the overall rigidity of the protective frame 5, but also provides a protection space for the driving member 6.

[0033] It should be noted that the uniform distribution of the protective rods 502 ensures the balance and stability of the protective frame 5, making the entire electric butterfly valve more stable and reliable during operation.

[0036] Further, the flanges 11 are fixedly connected to the left and right edges of the valve body 1, and the support blocks 12 are fixedly connected between the two flanges 11.

[0037] In the embodiment, the arc-shaped bending structures at the left and right ends of the channel pipe 7 can effectively reduce the turbulence and pressure loss generated when the fluid passes through, and ensure smooth flow of the fluid in the channel pipe 7, and meanwhile, the sealing ring 10 is used to ensure that the fluid cannot leak from the gap between the valve plate 8 and the channel pipe 7, thereby improving the sealing performance of the valve.

[0038] It should be noted that the use of the flanges 11 and the support blocks 12 can not only enhance the overall structural strength of the valve body 1, but also ensure stable operation of the valve under various working conditions.
