The three-piece ball valve is a versatile and efficient type of valve that is widely used in various industrial applications due to its numerous advantages. Here's a summary of the key points from your product introduction:
1. **Structure**: The three-piece ball valve consists of a main valve body and two auxiliary valve bodies, with the ball core and valve stem installed in the main body. The secondary valve body is seated and connected to the main body with bolts.
2. **Connection Types**: It offers both internal and external thread connections. The internal threads are typically 55° taper pipe threads, and the external threads are sealed with welded joints for good sealing and can be directly welded to the pipeline.
3. **Maintenance**: The three-piece design allows for easier maintenance and disassembly. You can loosen the valve body wire, remove a bolt, and replace the seat ring by turning the main valve body. The entire main valve body can also be removed for maintenance without taking the secondary valve body offline.
4. **Welding Options**: Butt welding and socket welding are available, with the option to extend the nozzle for welding to protect the valve seat sealing ring and valve stem packing from high temperatures during the welding process.
5. **Online Maintenance**: A key feature of the three-piece ball valve is the ability to perform maintenance without taking the valve offline, significantly reducing downtime and maintenance workload.
6. **Operation**: The ball valve operates by rotating the ball around the center line of the valve body, which is used to open and close the valve. It requires only a 90-degree rotation from full open to full closed, making it easy to operate and suitable for remote control.
7. **Advantages**:
- Low fluid resistance, with a resistance coefficient equal to that of a pipe segment of the same length.
- Simple structure, compact size, and lightweight.
- Reliable sealing, with a wide range of sealing surface materials including plastics, suitable for vacuum systems.
- Easy to operate and quick to open and close.
- Easy maintenance due to the simple structure and replaceable sealing rings.
- The sealing surface is isolated from the medium when fully open or closed, preventing erosion.
- Broad application range, suitable for various sizes and pressures.
8. **Variety**: The three-piece ball valve is available in different types, including flanged ball valves, flanged gate valves, and knife gate valves, catering to diverse industrial needs.
This product introduction highlights the three-piece ball valve as a robust, low-maintenance, and user-friendly option for controlling the flow of various media in pipelines. Its design and features make it an excellent choice for industries looking to optimize their fluid control systems.
