Description

Technical Field

[0001] This utility model relates to the field of ball valve equipment technology, and in particular to an integrated fluoropolymer-lined ball valve. Background Technology

[0002] Control valves are important devices used to regulate process parameters such as flow rate, pressure, temperature, and liquid level in industrial automation process control. With the continuous development of industrial automation, control valves are playing an increasingly important role in various fields such as petrochemicals, power, metallurgy, and pharmaceuticals.

[0003] Traditional control valves often only have a single control method, lacking flexibility and unable to meet the needs of different application scenarios. Furthermore, the installation process of some control valves is quite complicated, requiring a lot of time and manpower. Disassembly and maintenance are also cumbersome, which is not conducive to rapid response and reducing maintenance costs. In order to solve the above problems, this utility model provides an integrated PTFE-lined ball valve. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an integrated fluoropolymer-lined ball valve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An integrated PTFE-lined ball valve includes a valve tube, inside which a ball valve assembly is disposed. A lower flange is fixedly connected to the upper end of the valve tube surface. An upper flange is fixedly mounted on the upper surface of the lower flange. A connecting seat is fixedly connected to the upper surface of the upper flange. A mounting frame is fixedly connected to the upper surface of the connecting seat. A transmission rod is rotatably connected inside the mounting frame. An adjustment assembly is provided on the front of the mounting frame. A mounting shell is fixedly connected to the upper surface of the mounting frame.

[0007] As a further improvement of this utility model, the ball valve assembly includes sealed bearings disposed at the upper and lower ends inside the valve tube, a ball valve body is rotatably connected between the two sealed bearings, and an installation rod is rotatably connected inside the lower flange, with the lower end of the installation rod passing through the sealed bearings and fixedly connected to the ball valve body.

[0008] As a further improvement of this utility model, the upper end of the mounting rod is provided with a connecting slot, and the lower end of the transmission rod is fixedly connected with a connecting block that matches the connecting slot.

[0009] As a further improvement of this utility model, the adjusting component includes a connecting bearing disposed on the front of the mounting frame, a connecting rod rotatably connected inside the connecting bearing, a first bevel gear fixedly connected to the surface of the transmission rod, a second bevel gear fixedly connected to one end of the connecting rod, the first bevel gear and the second bevel gear meshing with each other, and a handle fixedly connected to the other end of the connecting rod.

[0010] As a further improvement of this utility model, a servo motor is fixedly connected inside the mounting shell, and the power end of the servo motor is fixedly connected to the transmission rod.

[0011] As a further improvement of this utility model, sealing rings are fixedly connected to the upper end of the lower flange and the lower end of the upper flange. Several threaded holes are opened at the upper end of the lower flange, and several mounting bolts that are compatible with the threaded holes are threadedly connected to the upper end of the upper flange. Connecting flanges are fixedly connected to both ends of the valve pipe.

[0012] The beneficial effects of this utility model are:

[0013] By setting up the ball valve assembly, the precise docking of the connecting block and the connecting groove, as well as the convenient docking of the upper flange and the lower flange, simplifies the installation process, improves work efficiency, and facilitates subsequent disassembly and maintenance, reducing operational difficulty and cost. At the same time, through the coordinated use of the connecting block, the connecting groove, and the sealed bearing, the transmission rod can stably drive the mounting rod and the ball valve body to rotate inside the sealed bearing, improving the stability and reliability of the transmission and extending the service life of the equipment. In addition, the sealing ring effectively ensures the sealing between the upper flange and the lower flange, preventing media leakage, thereby ensuring the safety and stability of the valve system.

[0014] By incorporating adjustment components, this invention integrates both electric and manual adjustment functions during use. Under normal circumstances, the servo motor can be activated to electrically adjust the ball valve body, improving the accuracy and automation of the adjustment. In emergency situations, the angle of the ball valve body can be quickly adjusted by manually operating the handle, ensuring the reliability and emergency response capability of the system. This allows the device to flexibly select the adjustment method according to actual needs, improving the system's flexibility and adaptability, while also increasing system redundancy and stability.

[0015] In summary, this utility model, through its unique design and innovative technical means, achieves beneficial effects such as rapid installation and disassembly, excellent sealing performance, flexible adjustment methods, stable transmission mechanism, and compact structure.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 An integrated PTFE-lined ball valve includes a valve pipe 1, a ball valve assembly inside the valve pipe 1, a lower flange 2 fixedly connected to the upper end of the surface of the valve pipe 1, an upper flange 3 fixedly installed on the upper surface of the lower flange 2, a connecting seat 4 fixedly connected to the upper surface of the upper flange 3, a mounting frame 5 fixedly connected to the upper surface of the connecting seat 4, a transmission rod 6 rotatably connected inside the mounting frame 5, an adjustment assembly provided on the front of the mounting frame 5, and a mounting shell 7 fixedly connected to the upper surface of the mounting frame 5.

[0023] In this utility model, the ball valve assembly includes sealed bearings 8 disposed at the upper and lower ends inside the valve pipe 1. A ball valve body 9 is rotatably connected between the two sealed bearings 8. An installation rod 10 is rotatably connected inside the lower flange 2. The lower end of the installation rod 10 passes through the sealed bearings 8 and is fixedly connected to the ball valve body 9. A connecting groove 11 is provided at the upper end of the installation rod 10. A connecting block 12 that matches the connecting groove 11 is fixedly connected at the lower end of the transmission rod 6 inside the mounting frame 5. This ensures that the connecting block 12 equipped at the lower end of the transmission rod 6 inside the mounting frame 5 can be accurately aligned with the connecting groove 11 on the installation rod 10 inside the lower flange 2, thereby smoothly inserting the connecting block 12 into the connecting groove 11 to form a stable mechanical connection. At the same time, the upper flange 3 at the lower part of the mounting frame 5 is connected to the lower flange 2 of the valve pipe 1.

[0024] The adjustment assembly includes a connecting bearing 13 located on the front of the mounting frame 5. A connecting rod 14 is rotatably connected inside the connecting bearing 13. A first bevel gear 15 is fixedly connected to the surface of the transmission rod 6. A second bevel gear 16 is fixedly connected to one end of the connecting rod 14. The first bevel gear 15 and the second bevel gear 16 mesh with each other. A handle 17 is fixedly connected to the other end of the connecting rod 14. A servo motor 18 is fixedly connected inside the mounting housing 7. The power end of the servo motor 18 is fixedly connected to the transmission rod 6, so that the connecting rod 14 can be driven to rotate manually using the handle 17, thereby driving the second bevel gear 16 to rotate. The second bevel gear 16 drives the first bevel gear 15 and the transmission rod 6 to rotate synchronously through the meshing relationship, thereby realizing the rapid adjustment of the angle of the ball valve body 9, ensuring that the flow of the medium can be quickly responded to and controlled in an emergency.

[0025] A sealing ring 19 is fixedly connected to the upper end of the lower flange 2 and the lower end of the upper flange 3. Several threaded holes are opened at the upper end of the lower flange 2, and several mounting bolts 20 that are compatible with the threaded holes are threadedly connected to the upper end of the upper flange 3. Both ends of the valve pipe 1 are fixedly connected to the connecting flange 21. The upper flange 3 and the lower flange 2 are firmly fixed together by the mounting bolts 20, thereby constructing a stable and reliable connection structure. The sealing ring 19 ensures that a tight seal is formed between the lower flange 2 and the upper flange 3, effectively preventing media leakage.

[0026] When using this utility model, firstly, align the connecting block 12 at the lower end of the transmission rod 6 inside the mounting frame 5 with the connecting slot 11 of the mounting rod 10 inside the lower flange 2, and insert the connecting block 12 into the connecting slot 11. At the same time, the upper flange 3 under the mounting frame 5 and the lower flange 2 of the valve pipe 1 are connected. Use the mounting bolts 20 to fix the two together. Then, start the servo motor 18 to drive the transmission rod 6 to rotate. The transmission rod 6 drives the mounting rod 10 and the ball valve body 9 to rotate inside the sealing bearing 8 through the connecting block 12 and the connecting slot 11. Finally, in an emergency, the handle 17 can be used to drive the connecting rod 14 and the second bevel gear 16 to rotate. The second bevel gear 16 can drive the first bevel gear 15 and the transmission rod 6 to rotate synchronously, thereby adjusting the angle of the ball valve body 9.
