“หัวใจ” ของวาล์ว: บทบาทของตัววาล์ว แผ่นวาล์ว และส่วนประกอบการปิดผนึก
- วาล์วเดลโก้
Valve is a key component in the industrial piping system, so what makes the valve can be stable and efficient work? The answer lies in its “heart” – the valve body, disc and sealing components. The following DELCO Valve will be in-depth analysis of the role of these three parts and their common materials to help you better understand the valve.
Valve Body: The Foundation of a Valve
Valve body is the main structure that houses all the internal components. It provides the necessary strength to withstand pressure and temperature variations.
Key Functions of Valve Body
- ที่อยู่อาศัย: Encases the disc, stem, and other internal parts.
- Connection: Facilitates the attachment of the valve to pipelines via flanges, threads, or welds.
- Pressure Resistance: Designed to handle the operating pressure of the system.
Common Materials for Valve Body
- Cast Iron: Cost-effective and suitable for low-pressure applications.
- Stainless Steel: Offers excellent corrosion resistance and durability for harsh environments.
- Carbon Steel: Ideal for high-pressure and high-temperature applications.
Valve Disc: The Flow Regulator
The disc (or closure member) is the part that moves to control the flow of media through the valve. It’s the component that opens, closes, or throttles the flow.
Key Functions of Valve Disc
- Flow Control: Regulates the flow rate by opening, closing, or partially obstructing the passage.
- Pressure Management: Helps maintain system pressure by sealing tightly when closed.
Common Materials for Valve Disc
- Bronze: Used in low-pressure and non-corrosive environments.
- Stainless Steel: Resistant to corrosion and wear, suitable for a wide range of applications.
- PTFE (Polytetrafluoroethylene): Offers excellent chemical resistance for corrosive media.
Sealing Components: The Leak Preventers
Sealing components, such as gaskets and O-rings, ensure that the valve remains leak-free during operation. They are critical for maintaining the integrity of the system.
Key Functions of Sealing Components
- Leak Prevention: Creates a tight seal to prevent media from escaping.
- Friction Reduction: Minimizes wear between moving parts, extending the valve’s lifespan.
Common Materials for Sealing Components
- EPDM (Ethylene Propylene Diene Monomer): Ideal for water and steam applications.
- Nitrile Rubber: Suitable for oil and fuel systems.
- PTFE: Offers superior chemical resistance and is used in corrosive environments.
Conclusion
The valve body, valve disc and Components are the heart of a properly functioning valve. Understanding what they are and what they are made of can help you make a more informed choice when purchasing. Browse our catalog or contact our sales team for expert advice and quality valve solutions!
