Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, and in particular to a stainless steel ball valve with independent on / off control. Background Technology

[0002] In the fields of industrial automation and fluid control, stainless steel ball valves are widely used due to their excellent corrosion resistance and sealing performance. With continuous technological advancements, independently controllable stainless steel ball valves not only enhance operational flexibility but also play a crucial role in fluid control components. The design of these valves allows users to quickly open or close fluid passages when needed, effectively managing fluid flow and ensuring the safety and reliability of components. Furthermore, the independent control design concept enables them to be integrated with various automation components, adapting to different working environments and requirements, further enhancing the overall performance of the equipment.

[0003] Existing stainless steel ball valves typically employ a simple mechanical structure, with on / off control achieved via levers or electric actuators. This design mainly comprises a valve body, a ball, a valve stem, and a manual or electric actuation device. The valve stem is connected to the ball; rotating the valve stem changes the opening direction of the ball, thereby controlling fluid flow. In electric ball valves, a motor drives the valve stem to rotate, achieving precise flow control.

[0004] However, existing technologies have certain problems. During long-term rotation, wear occurs between the stainless steel hollow ball and the sealing element, leading to gaps between them and the equipment, thus reducing sealing performance. This wear not only affects the normal operation of the equipment but also causes fluid leakage, increasing maintenance and replacement costs. Therefore, an independently controllable stainless steel ball valve is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a stainless steel ball valve with independent on / off control, which aims to improve the problem that the stainless steel hollow ball will wear during long-term rotation, resulting in gaps between it and the equipment and reduced sealing performance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A stainless steel ball valve with independent switch control includes a ball valve, a stainless steel hollow ball rotatably connected inside the ball valve, a sealing component provided on the outer wall of the stainless steel hollow ball, a transmission column fixedly connected to the top of the stainless steel hollow ball, a connecting block fixedly connected to the top of the transmission column, a rotating handle fixedly connected to the outer wall of the connecting block, and a fixing component provided at the bottom of the rotating handle.

[0008] The sealing assembly includes multiple rubber rings located on both sides of the stainless steel hollow sphere. A fixing ring is fixedly connected to both sides of the inner wall of the ball valve. Each rubber ring is slidably connected to the inner wall of the fixing ring. Multiple springs are installed inside each fixing ring. One end of each spring is fixedly connected to the outer wall of the rubber ring, and the other end is fixedly connected to the inner wall of the fixing ring. Multiple rubber strips are fixedly connected to one end of each rubber ring.

[0009] As a further description of the above technical solution:

[0010] The fixing component includes a locking pin located at the bottom of the rotating handle, a transmission pin rotatably connected to the inside of the ball valve, and a rubber strip that fits against the outer wall of the stainless steel hollow ball.

[0011] As a further description of the above technical solution:

[0012] A connecting ring is fixedly connected to the bottom of the rotating handle, and a second fixing ring is rotatably connected to the outer wall of the connecting ring. The bottom of the second fixing ring is fixedly connected to the top of the ball valve.

[0013] As a further description of the above technical solution:

[0014] The connecting ring has multiple slots inside, and the ball valve has a connecting bracket fixedly connected to its outer wall.

[0015] As a further description of the above technical solution:

[0016] The connecting frame is rotatably connected to a rotating bar, and multiple guide rings are fixedly connected to the outer wall of the rotating bar.

[0017] As a further description of the above technical solution:

[0018] A pressing plate is fixedly connected to one side of the guide ring, and a connecting block three is fixedly connected to one side of the pressing plate.

[0021] As a further description of the above technical solution:

[0022] A second spring is provided on one side of the connecting frame. One end of the second spring is fixedly connected to the outer wall of the pressing plate, and the other end of the second spring is fixedly connected to the outer wall of the connecting frame.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the elasticity of the spring is used to push the rubber ring and the stainless steel hollow sphere to fit together, and the rubber strip is used to expand the contact area between the rubber ring and the outer wall of the stainless steel hollow sphere, so that the rubber ring and rubber strip fit more tightly with the outer wall of the stainless steel hollow sphere, achieving a sealing effect between the equipment and the inner wall of the stainless steel hollow sphere. This solves the problem that the stainless steel hollow sphere will wear during long-term rotation, resulting in gaps between it and the equipment and reduced sealing performance, thus enhancing the sealing performance between the stainless steel hollow sphere and the equipment.

[0025] 2. In this utility model, the elasticity of the second spring pushes the locking post to engage with the inner wall of the slot, thereby achieving the effect of fixing the rotation angle of the rotating handle. This solves the problem that the rotating handle may accidentally rotate due to external collisions or other factors during the use of the equipment, and enhances the stability of the rotation angle of the rotating handle.

[0033] 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.

[0034] Reference Figures 1-3 An embodiment of this utility model is provided: a stainless steel ball valve with independent switch control, including a ball valve 1, a stainless steel hollow ball 5 rotatably connected inside the ball valve 1, a sealing component provided on the outer wall of the stainless steel hollow ball 5, a transmission column 4 fixedly connected to the top of the stainless steel hollow ball 5, the transmission column 4 rotatably connected inside the ball valve 1, a connecting block 3 fixedly connected to the top of the transmission column 4, a rotating handle 2 fixedly connected to the outer wall of the connecting block 3, and a fixing component provided at the bottom of the rotating handle 2;

[0035] The sealing assembly includes multiple rubber rings 8, located on both sides of the stainless steel hollow sphere 5. These rubber rings 8 possess excellent elasticity and sealing performance, effectively preventing liquid or gas leakage and ensuring the tightness of the component. Fixed rings 6 are fixedly connected to both sides of the inner wall of the ball valve 1, providing structural support and ensuring the stability of the rubber rings 8 during operation. Each rubber ring 8 is slidably connected to the inner wall of the fixed ring 6, allowing for some displacement when pressure changes to adapt to different working conditions. Multiple springs 7 are installed inside each fixed ring 6, with one end fixedly connected to the outer wall of the rubber ring 8 and the other end fixedly connected to the inner wall of the fixed ring 6. The function of the springs 7 is to provide additional compressive force, ensuring good contact between the rubber ring 8 and the stainless steel hollow sphere 5. Thus, even under high pressure, the sealing assembly can maintain a stable sealing effect. Multiple rubber strips 9 are fixedly connected to one end of each rubber ring 8, and these rubber strips 9 are in contact with the outer wall of the stainless steel hollow sphere 5.

[0036] Specifically, an advanced sealing structure design is adopted in the sealing process of the stainless steel hollow sphere 5. Utilizing the arc-shaped characteristics of the wall of the stainless steel hollow sphere 5, the rubber ring 8 on one side of the rubber strip 9 can be effectively pushed to slide inside the fixed ring 6. The design of the fixed ring 6 aims to reasonably limit the movement direction of the rubber ring 8, ensuring the stability and safety of the component. During this process, the movement of the rubber ring 8 directly causes the compression of the spring 7, generating extrusion force. The rebound force of the spring 7 after being compressed effectively pushes the rubber ring 8, applying uniform extrusion force to the outer wall of the stainless steel hollow sphere 5. The use of the rubber strip 9 not only improves the sealing effect but also significantly expands the contact area between the rubber ring 8 and the stainless steel hollow sphere 5, thereby enhancing the tightness of their fit. Ultimately, this achieves excellent sealing performance between the stainless steel hollow sphere 5 and the equipment, effectively preventing leakage and ensuring the stable and safe operation of the component.

[0037] Reference Figure 1 , Figure 4 and Figure 5 The fixing component includes a locking pin 20, located at the bottom of the rotating handle 2, used to fix the handle 2 after its angle is adjusted. A connecting ring 11 is fixedly connected to the bottom of the rotating handle 2, and a fixing ring 10 is rotatably connected to the outer wall of the connecting ring 11, providing a support structure for easy operation of the rotating handle 2. The bottom of the fixing ring 10 is fixedly connected to the top of the ball valve 1, ensuring the stability and reliability of the fixing component in the overall assembly. Multiple slots 12 are provided inside the connecting ring 11, which are used to cooperate with the locking pin 20 to form an effective locking structure, ensuring the fixing of the rotating handle 2 at the required angle position. A connecting frame 14 is fixedly connected to the outer wall of the ball valve 1, and the connecting frame 14 is rotatably connected inside. A rotating bar 15 is connected, and the rotation of the rotating bar 15 enables the opening and closing operation of the ball valve 1, enhancing the functionality of the overall device. Multiple guide rings 16 are fixedly connected to the outer wall of the rotating bar 15. The main function of the guide rings 16 is to guide the movement trajectory of the connecting block 19 and ensure its precise sliding. A pressing plate 18 is fixedly connected to one side of the guide ring 16. The design of the pressing plate 18 enables it to effectively transmit the applied force during operation. A connecting block 19 is fixedly connected to one side of the pressing plate 18. The outer wall of the connecting block 19 fits against the inner wall of the connecting block 13, which can effectively transmit the action of the pressing plate 18. The connecting block 13 is slidably connected inside the fixed ring 10, allowing it to move freely within a certain range. A locking post 20 is fixedly connected to one side of the connecting block 2 13. The locking post 20 engages with the inner wall of the slot 12, ensuring that the rotating handle 2 is not easily loosened during adjustment. A spring 2 17 is provided on one side of the connecting frame 14. One end of the spring 2 17 is fixedly connected to the outer wall of the pressing plate 18, and the other end of the spring 2 17 is fixedly connected to the outer wall of the connecting frame 14.

[0038] Specifically, during the process of fixing the angle of the rotating handle 2, the pressing plate 18 needs to be pressed first. This operation causes the guide ring 16 on one side of the pressing plate 18 to rotate on the outer wall of the rotating bar 15, while simultaneously applying compression force to the spring 17. As the pressing plate 18 moves, the connecting block 19 will be driven, thereby causing the connecting block 13 to slide inside the fixing ring 10 until the locking pin 20 is pushed to the inner wall of the slot 12. Then, the rotating handle 2 will be rotated, and the connecting ring 11 will also rotate on the inner wall of the fixing ring 10. After the rotation of the handle 2 is completed, the operator will release the pressure applied to the pressing plate 18. Utilizing the rebound force of the spring 17, the locking post 20 will automatically engage with the inner wall of the slot 12, thereby effectively fixing the angle of the handle 2. This process ensures that the handle 2 is not easily affected by external factors and will not rotate accidentally during use, enhancing the stability and safety of its angle fixation. This allows the equipment to maintain a reliable operating state during operation, enabling users to perform related operations with greater peace of mind and improving the overall user experience and safety of the equipment.

[0039] Working principle: During the sealing process of the stainless steel hollow sphere 5, the arc surface of the outer wall of the stainless steel hollow sphere 5 pushes the rubber ring 8 on one side of the rubber strip 9 to slide inside the fixed ring 6. The fixed ring 6 limits the movement direction of the rubber ring 8 and pushes the spring 7 to generate compression. The rebound force of the spring 7 pushes the rubber ring 8 to compress the outer wall of the stainless steel hollow sphere 5. The rubber strip 9 expands the contact area between the rubber ring 8 and the stainless steel hollow sphere 5, enhancing the tightness of the fit between the rubber ring 8 and the rubber strip 9 and the stainless steel hollow sphere 5, thus achieving the sealing between the stainless steel hollow sphere 5 and the equipment.

[0040] During the process of fixing the rotation angle of the rotary handle 2, the pressing plate 18 is pressed, causing the guide ring 16 on one side of the pressing plate 18 to rotate on the outer wall of the rotating bar 15, and compressing the spring 17. While the pressing plate 18 is moving, it will also drive the connecting block 13 to slide inside the fixing ring 10 through the connecting block 19 until the locking pin 20 is pushed out of the inner wall of the slot 12. Next, the rotary handle 2 is rotated, causing the connecting ring 11 to rotate on the inner wall of the fixing ring 10. After the rotary handle 2 has finished rotating, the pressing force on the pressing plate 18 is released. Through the above principle, the rebound force of the spring 17 is used to push the locking pin 20 to engage with the inner wall of the slot 12, thereby fixing the angle of the rotary handle 2 and preventing external factors from accidentally pushing the rotary handle 2 to rotate, thus enhancing the fixation of the angle of the rotary handle 2.

[0041] 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.
