Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a high-performance ball-type sealing butterfly valve. Background Technology

[0002] A butterfly valve is a type of valve that uses a disc-shaped butterfly plate as its opening and closing element. By rotating the butterfly plate around the valve stem, it controls the flow of fluid and regulates the flow rate. It features simple structure, small size, light weight, and convenient operation, and is widely used in the field of fluid control. Currently, traditional ball-type sealing butterfly valves achieve valve opening and closing and flow regulation by rotating the valve plate driven by the valve stem. When the valve plate rotates to be parallel to the valve body channel axis, the valve is in the fully open state, and the fluid can pass through smoothly. When rotated to be perpendicular to the axis, the valve is completely closed, blocking the fluid passage. Due to its ball-type sealing structure, it can provide better sealing performance when closed, reducing fluid leakage. While traditional ball-type sealed butterfly valves can control the opening and closing of the valve, they cannot protect against emergencies or provide backup control in case of equipment failure. Therefore, a high-performance ball-type sealed butterfly valve is proposed to solve these problems. Utility Model Content

[0009] 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.

[0010] Reference Figures 1-5 This utility model provides an embodiment of a high-performance spherical sealing butterfly valve, comprising a frame 1, with auxiliary supports 2 fixedly connected to both the left and right sides of the frame 1, and a fixed seat 3 fixedly connected to the inner side of the frame 1. The fixing of the frame 1 and the auxiliary supports 2 enhances the overall support strength. The sliding fit between the fixed seat 3 and the flange 5 facilitates installation and adjustment. The isolation ring 17 ensures the sealing and sliding stability of the ball valve frame 20 and the flange 5. With the upper and lower valve assemblies controlling the ball valve gate 21, the valve achieves convenient installation, stable structure, and reliable sealing performance. The flange 5 is slidably connected to the top side of the fixed seat 3, and the outer side of the flange 5 is slidably connected to the inner side of the frame 1. Bolts 6 are threadedly connected to the outer side of the flange 5. A valve pipe 30 is fixedly connected to the bottom side of the flange 5. Isolation rings 17 are installed on the inner side of the flange 5. The ball valve frame 20 is slidably connected to the inner side of the isolation ring 17. The ball valve gate 21 is slidably connected to the inner side of the ball valve frame 20. An upper valve assembly is installed on the top side of the ball valve gate 21, and a lower valve assembly is installed on the bottom side of the ball valve gate 21. A control base plate 14 is fixedly connected to the top side of the ball valve frame 20.

[0011] Reference Figures 1-4A rotating shaft 27 is slidably connected to the top side of the control base plate 14. A threaded shaft 11 is fixedly connected to the top side of the rotating shaft 27. A rotating shaft 12 is threadedly connected to the outer side of the threaded shaft 11. A rotating rod 13 is fixedly connected to the inner side of the rotating shaft 12. A drive rod 9 is fixedly connected to the top side of the rotating shaft 12. A middle plate 26 is slidably connected to the bottom side of the drive rod 9. At the same time, the middle plate 26 and the top plate 7 form a stable support frame 1, which not only provides precise installation positioning and sliding guidance for components such as the drive rod 9 and the threaded shaft 11, but also counteracts the lateral force generated during transmission, preventing components from jamming or wearing due to force deviation. The bottom side of the middle plate 26 is fixedly connected to the top side of the control base plate 14. A turntable 10 is fixedly connected to the outer side of the drive rod 9. A secondary disc 8 is installed on the top side of the threaded shaft 11. The top plate 7 is fixedly connected to the top side of the middle plate 26.

[0012] Reference Figures 2-4 The upper valve assembly includes an upper snap fastener 29, which is fixedly connected to the inner side of the ball valve gate 21 on the outside. An upper rotating shaft 24 is rotatably connected to the top side of the upper snap fastener 29, and the outer side of the upper rotating shaft 24 is fixedly connected to the outer side of the ball valve frame 20. Through the fixed connection between the upper snap fastener 29 and the ball valve gate 21, and the rotatable connection between the upper snap fastener 29 and the upper rotating shaft 24, the ball valve gate 21 can be driven to rotate flexibly. At the same time, the fixed connection between the upper rotating shaft 24 and the ball valve frame 20 provides stable support, thereby achieving a flexible and controllable effect when the ball valve gate 21 is opened and closed, making the operation more precise.

[0013] Reference Figures 2-5 The lower valve assembly includes a lower rotary buckle 28, which is fixedly connected to the inner side of the ball valve gate 21 on its outer side. A lower rotary shaft 23 is rotatably connected to the bottom side of the lower rotary buckle 28. A lower frame 22 is fixedly connected to the outer side of the lower rotary shaft 23. The outer side of the lower rotary shaft 23 is slidably connected to the inner side of the ball valve frame 20. The fixed connection between the lower rotary buckle 28 and the ball valve gate 21, and the rotatable connection between the lower rotary buckle 28 and the lower rotary shaft 23, drive the ball valve gate 21 to rotate flexibly. At the same time, the slidable connection between the lower rotary shaft 23 and the ball valve frame 20 provides stable guidance, thereby achieving smooth opening and closing of the ball valve gate 21 and reducing jamming.

[0014] Working principle: Frame 1 serves as the main support structure for the valve body. The auxiliary supports 2 on both sides enhance the overall stability. The bumper 4 further resists external impacts. The fixed seat 3 provides the installation base for the flange 5. The flange 5 can slide and adjust its position along the fixed seat 3 and the inner side of the frame 1. After adjustment, it is fixed by bolts 6. The outer gasket 18 and the inner gasket 19 fill the connection gap between the flange 5 and the valve pipe 30, initially ensuring the sealing between the valve pipe 30 and the flange 5. The operator rotates the turntable 10, and the driving force is transmitted to the rotating shaft 12 through the drive rod 9. The rotating shaft 12 enhances the structural rigidity through the inner rotating rod 13, and at the same time maintains stable rotation under the guidance and support of the middle plate 26. The rotating shaft 12 and the threaded shaft 11 realize the conversion of force through the threaded engagement, converting the rotational motion into the axial transmission of the threaded shaft 11. The auxiliary plate 8 can assist the threaded shaft 11 in maintaining balance, and the top plate 7 provides protection and limit for the top transmission components. The threaded shaft 11 drives the bottom rotating shaft 27 to move. The rotating shaft 27 is fixedly connected to the upper rotating shaft 24, transmitting power to the upper rotating shaft 24. The upper rotating shaft 24 is securely connected to the ball valve frame 20 through the outer spiral thread 25. At the same time, it drives the ball valve gate 21 to move synchronously through the upper rotating buckle 29. The control base plate 14 fixes the ball valve frame 20 through the fixing bolt 16 and the clamp 15 to ensure the stability of the ball valve frame 20 during transmission. Under the driving force of the upper rotating shaft 24 at the top and the guiding action of the lower rotating shaft 23 at the bottom, the ball valve gate 21 rotates the upper rotating buckle 29 to fix itself to the ball valve gate 21. As the upper rotating shaft 24 rotates, it drives the top of the ball valve gate 21 to move synchronously. The lower screw 28 is fixed to the inside of the ball valve gate 21 and slides along the inside of the ball valve frame 20 via the lower screw shaft 23. The lower bracket 22 provides bottom support for the lower screw shaft 23 to ensure the accurate rotation trajectory of the ball valve gate 21. When the ball valve gate 21 is closed, it fits tightly with the ball valve frame 20. The isolation ring 17 inside the flange 5 fills the gap between the ball valve frame 20 and the flange 5, forming a multi-seal structure with the outer gasket 18 and the inner gasket 19 to prevent fluid leakage from the connection between the valve pipe 30 and the ball valve frame 20. When open, the ball valve gate 21 rotates in the opposite direction, the flow channel opens, and the sliding characteristics of the isolation ring 17 reduce the frictional resistance when the ball valve frame 20 rotates, ensuring smooth opening and closing.

[0015] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
