Product Description
I. Definition and Structure
The extended - stem wafer - type butterfly valve is a special type of butterfly valve. The opening and closing component is the disc, which is driven by an extended valve stem and rotates 90° around its own axis inside the valve body to achieve opening, closing, or regulation. The disc is installed in the diameter direction of the pipeline and rotates around the axis within the cylindrical passage of the valve body. The extended - stem design enables easy remote operation in special environments.
II. Structural Features
- Simple and Lightweight Structure: The valve itself has a relatively simple structure with few components. The extended stem does not add to the complexity. It is small in size and light in weight, occupying little space and being easy to install.
- Effort - Saving Operation: The extended valve stem allows operators to work in a more comfortable position, reducing the operation difficulty and physical exertion.
- Reliable Sealing: It adopts special sealing structures (such as triple - offset multi - layer metal hard seals, soft seals, etc.). When closed, it can ensure no leakage of the medium. Some have an automatic - tightening sealing function as they close, and the sealing surface has compensation properties, enabling zero leakage.
- Convenient Flow Regulation: The rotation of the disc can regulate the medium flow. The extended stem does not affect this function. It has good flow characteristics and generates a small pressure drop.
III. Main Parts Materials
- Valve Body: Common materials include WCB (carbon steel), CF8 (stainless steel 304), CF8M (stainless steel 316), etc.
- Disc: Similar materials to the valve body, such as WCB, CF8, CF8M, etc.
- Valve Stem: Usually made of stainless steel materials like 304, 316, 1Cr13, etc., to ensure strength and corrosion resistance.
- Sealing Sleeve: Mostly made of stainless steel materials such as 316 and 304.
- Packing: Flexible graphite, fluoroplastics, etc., to enhance the sealing performance.
IV. Technical Parameters
- Nominal Diameter: Commonly ranges from DN40 to DN2000, meeting the requirements of pipelines with different diameters.
- Nominal Pressure: Such as PN0.6, PN1.0, PN1.6MPa, etc.
- Applicable Temperature: Varies according to the material and sealing structure, generally around - 15°C - 425°C.
V. Application Fields
- Industrial Pipeline Control: In industries such as petrochemical, power, and metallurgy, it is used to control fluid flow and pressure.
- Building Water Supply and Drainage Systems: Controls the flow of water, sewage, and other liquids in buildings.
- Automation Control Systems: Coordinates with sensors and actuators to precisely control parameters such as fluid flow, pressure, and temperature.
VI. Installation and Maintenance
- Installation: Place it between two flanges, align the bolt holes, insert bolts and nuts and tighten them slightly to correct the flatness of the flange surface. Spot - weld the flange to the pipeline, then remove the valve and weld the flange. After cooling, install the valve, ensuring there is room for the valve to move between the flanges and the disc has an opening degree. Correct the position and tighten the bolts (do not over - tighten). Open the valve to confirm that the disc can open and close freely. Slightly open the disc and then cross - tighten the nuts evenly. Confirm the opening and closing condition again and ensure the disc does not touch the pipeline.
- Maintenance: Regularly check the sealing performance and operational flexibility. For media prone to scaling, crystallization, or containing solid particles, pay attention to the material and sealing structure to avoid blockage or leakage.
