Description

Technical Field

[0001] This utility model relates to the field of butterfly valve technology, and more specifically, to a butterfly valve with anti-jamming function. Background Technology

[0002] In the field of industrial fluid control, butterfly valves are widely used as key components in various pipeline systems, undertaking the important tasks of controlling fluid flow and regulating flow. However, in actual operation, traditional butterfly valves often experience problems such as impurity accumulation, water deposition, and excessive friction between components, leading to valve plate jamming or even seizing. This not only affects the accuracy and stability of fluid control but also increases equipment maintenance costs and downtime risks. To solve these industry pain points and improve the reliability and durability of butterfly valves under complex working conditions, a butterfly valve with anti-jamming function has emerged.

[0003] A search revealed that publication number CN222963355U discloses a butterfly valve with an elastic disc, relating to the field of butterfly valve technology, and solving problems such as wear, jamming, and poor durability in existing technologies. The disc is entirely plate-shaped and made of elastic metal material. It includes an inner disc at the center and a contact portion on the outer periphery of the inner disc. The contact portion has a curved cross-section, its contour gradually moving away from the valve stem and then bending inwards towards the valve stem. The valve seat forms a sealing fit with the contact portion. The plate-shaped butterfly valve structure, integrally formed from elastic metal material, allows the contact portion to undergo radial expansion deformation during closure due to material elasticity. This adaptively compensates for sealing surface gaps caused by machining errors, thermal expansion, and media impurities, significantly reducing dependence on assembly precision. The curved profile of the contact portion, moving away from and then towards the valve stem, enhances the elastic deformation capability, gradually increasing the sealing surface contact pressure during the disc's rotational closure process. The inventors discovered the following problems with existing technologies during the development of this utility model:

[0004] Traditional butterfly valves without anti-jamming design are prone to jamming due to the accumulation of impurities and deposits in the pipeline during long-term use, affecting the normal opening and closing of the valve. Their transmission structure is also often prone to low power transmission efficiency and jamming due to high friction.

[0005] Therefore, a butterfly valve with anti-jamming function is proposed to address the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] As attached Figures 1 to 4 The butterfly valve shown includes a valve mechanism 1, a connecting component 2, and a support component 3. The connecting component 2 is provided on the outer diameter surface of the valve mechanism 1, and the support component 3 is installed above the connecting component 2.

[0026] The butterfly valve consists of a valve mechanism 1, a connecting component 2, and a support component 3 working together. The valve mechanism 1 controls the flow of fluid and achieves efficient power transmission and valve plate rotation through a precisely designed internal transmission structure. It also has a built-in anti-jamming component to reduce the risk of jamming caused by impurities. The connecting component 2 serves as the hub connecting the valve to the pipeline, providing a fluid channel and having drainage and impurity removal functions. It can promptly remove accumulated water and sediment in the pipeline, preventing scale buildup and jamming in the valve from the source. The support component 3 provides stable support for the valve mechanism 1 and the connecting component 2. Through a sealing design, it prevents fluid leakage and the intrusion of external impurities, reduces internal wear, and ensures long-term stable operation of the valve.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0029] In a preferred embodiment, the valve mechanism 1 includes a drive assembly 4, a transmission assembly 5, and a switch assembly 6. The transmission assembly 5 is disposed on the side of the drive assembly 4, and the switch assembly 6 is disposed below the transmission assembly 5. When liquid needs to pass through the butterfly valve, the operator needs to start the drive assembly 4. The drive assembly 4 and the transmission assembly 5 are engaged, and the transmission assembly 5 and the switch assembly 6 are engaged. Therefore, when the drive assembly 4 starts to rotate, the transmission assembly 5 will also rotate, and drive the switch assembly 6 to rotate, thereby realizing the opening and closing of the valve.

[0030] In a preferred embodiment, the drive assembly 4 includes a motor 7, a first rotating shaft 8, and a drive gear 9. The first rotating shaft 8 is mounted on the side of the motor 7, and the drive gear 9 is mounted on the outer diameter surface of the first rotating shaft 8. The first rotating shaft 8 and the first housing 19 are connected by a bearing. The motor 7 drives the drive gear 9 to rotate through the first rotating shaft 8 to realize power input. The bearing connects the first rotating shaft 8 and the first housing 19 to reduce rotational friction, ensure efficient power transmission, and avoid jamming. The drive gear 9 meshes with the reduction gear 10 of the transmission assembly 5 to form a primary transmission.

[0031] In a preferred embodiment, the transmission assembly 5 includes a reduction gear 10, a first bevel gear 11, and a second rotating shaft 12. The second rotating shaft 12 is mounted on the inner diameter surface of the reduction gear 10, and the first bevel gear 11 is provided on the side of the reduction gear 10. The second rotating shaft 12 and the first housing 19 are connected by bearings. The reduction gear 10 receives the power of the drive gear 9 through the second rotating shaft 12, and transmits it to the first bevel gear 11 after reduction. The bevel gear structure converts horizontal rotation into vertical rotation, and changes the direction of power through the second bevel gear 13 to drive the switch assembly 6. The reduction design can reduce the transmitted speed and increase the torque to adapt to the smooth power required for the valve plate 15 to switch.

[0032] In a preferred embodiment, the switch assembly 6 includes a second bevel gear 13, a third rotating shaft 14, and a valve plate 15. The third rotating shaft 14 is mounted on the inner diameter surface of the second bevel gear 13, and the valve plate 15 is mounted below the third rotating shaft 14. The third rotating shaft 14 and the second housing 20 are connected by a bearing. The second bevel gear 13 meshes with the first bevel gear 11, driving the third rotating shaft 14 to rotate, thereby driving the valve plate 15 to rotate, allowing liquid to pass through the inside of the butterfly valve.

[0033] In a preferred embodiment, the connecting assembly 2 includes a connecting pipe body 16, a drain pipe 17, and a sealing cap 18. The drain pipe 17 is installed below the connecting pipe body 16, and the sealing cap 18 is installed below the drain pipe 17. The connecting pipe body 16 serves as the main body for connecting the valve and the pipeline, providing a fluid passage and ensuring smooth fluid flow. It also provides an installation interface for the drain pipe 17. When water or impurities accumulate in the pipeline, the sealing cap 18 can be opened to drain the water through the drain pipe 17. Furthermore, operators can periodically fill the connecting pipe body 16 with water and drain the water through the drain pipe 17, reducing the obstruction of the valve plate 15 rotation by deposits and reducing the risk of jamming from the source.

[0034] In a preferred embodiment, the support assembly 3 includes a first housing 19, a second housing 20, and a sealing ring 21. The second housing 20 is mounted on the side of the first housing 19, and the sealing ring 21 is mounted on the outer diameter surface of the second housing 20. The first housing 19 and the second housing 20 provide mounting support for the drive assembly 4 and the transmission assembly 5, forming a closed cavity to protect the internal parts. The sealing ring 21 is mounted on the outside of the second housing 20 and fits tightly with the pipe interface to prevent fluid leakage.

[0035] In a preferred embodiment, the valve plate 15 includes a steel plate 22, a reinforcing rib 23, and a scraper 24. The reinforcing rib 23 is installed on the side of the steel plate 22, and the scraper 24 is installed on the side of the reinforcing rib 23 away from the steel plate 22. The operator can control the rotation angle of the valve plate 15 through the drive assembly 4 to control the flow rate of the liquid. The scraper 24 on the valve plate 15 rotates with the valve plate 15, closely adhering to the inner wall of the pipe to remove impurities and prevent the accumulation of debris from causing the valve plate 15 to jam. The reinforcing rib 23 enhances the rigidity of the valve plate 15 and avoids deformation and jamming during long-term use.

[0036] The working process of this utility model is as follows: First, the butterfly valve achieves anti-jamming and fluid control through the coordinated operation of valve mechanism 1, connecting component 2 and supporting component 3. Among them, valve mechanism 1 is the core part, including drive component 4, transmission component 5 and switch component 6. The motor 7 in drive component 4 drives drive gear 9 to rotate through first rotating shaft 8 connected by bearing, inputting power and transmitting it to reduction gear 10 of transmission component 5. After reduction gear 10 achieves reduction and torque increase through second rotating shaft 12, it converts horizontal rotation into vertical rotation through first bevel gear 11. Then, the second bevel gear 13 of switch component 6 meshes with and drives third rotating shaft 14, thereby driving valve plate 15 to rotate to control fluid flow. Valve plate 15 is made of steel plate 22, and its side reinforcing ribs 23 enhance rigidity. The scraper 24 on the side away from steel plate 22 adheres to the inner wall of the pipe to remove impurities when the valve plate 15 rotates, preventing the accumulation of debris from causing jamming.

[0037] The connecting pipe 16 of the connecting component 2 serves as the main body connecting the valve and the pipeline, providing a fluid passage. The drain pipe 17 and sealing cap 18 below it allow for the drainage of accumulated water or sediment by opening the sealing cap 18 when water or impurities accumulate in the pipeline. Operators can also periodically fill the connecting pipe 16 with water and drain it through the drain pipe 17, reducing the risk of jamming at the source. The first housing 19 and second housing 20 of the supporting component 3 provide installation support for the drive component 4 and transmission component 5, forming a closed cavity to protect internal parts. The sealing ring 21 on the outer diameter surface of the second housing 20 fits tightly with the pipeline interface, preventing fluid leakage and the intrusion of external impurities, ensuring efficient power transmission and avoiding jamming. Ultimately, through the synergistic effect of each component and part, the butterfly valve achieves its anti-jamming function and stable operation. This is the working principle of a butterfly valve with an anti-jamming function.
