تستخدم صمامات الفراشة على نطاق واسع في صناعات مختلفة لتنظيم التدفق في خطوط الأنابيب. على المدى “DN200” يشير إلى القطر الاسمي للصمام, الذي يلعب دورًا مهمًا في تحديد توافقه مع أنظمة الأنابيب. في هذه المقالة, we will explore the specifications, التطبيقات, and advantages of DN200 butterfly valves while also discussing related larger sizes such as DN800 and DN2000.
Understanding DN200 Butterfly Valves
1. What Does DN200 Mean?
DN200 refers to a nominal diameter of 200 ملليمتر (أو 8 بوصة). It represents the inner diameter of the pipeline the valve is designed to fit. This measurement is crucial for ensuring proper flow control and pipeline compatibility.
2. Key Specifications of DN200 Butterfly Valve
- مقاس: 200مم (8 بوصة)
- خيارات المواد: الحديد الزهر, الدكتايل الحديد, الفولاذ المقاوم للصدأ, or carbon steel
- تقييمات الضغط: Common ratings include PN10, PN16, or ANSI 150
- Connection Types: رقاقة, lug, or flanged
- آلية الختم: Soft-seated (إبدم, نبر) or metal-seated for high-temperature applications
3. Applications of DN200 Butterfly Valves
- محطات معالجة المياه: Used for flow regulation in pipelines
- أنظمة التدفئة والتهوية وتكييف الهواء: Controls air and water flow in heating and cooling systems
- زيت & Gas Industry: Helps in managing fluid transport in pipelines
- المعالجة الكيميائية: Handles corrosive or high-pressure fluids effectively
Considerations for Larger Sizes: DN800 and DN2000 Butterfly Valves
As pipeline diameters increase, the design and construction of butterfly valves become more complex.
- DN800 Butterfly Valves: With a nominal diameter of 800 مم, these valves are used in large-scale applications such as municipal water distribution and large industrial facilities. They often come equipped with gear operators or actuators to facilitate operation due to their size.
- DN 2000 صمامات الفراشة: هذه الصمامات, measuring 2000 mm in diameter, are utilized in major infrastructure projects, including dams and large water treatment plants. Their design must account for high pressure and flow rates, often incorporating double or triple eccentric designs to ensure reliable performance.
Why Choose a China Valve Manufacturer?
China has become a leading hub for butterfly valve manufacturing, offering cost-effective and high-quality solutions. When selecting a الشركة المصنعة للصمامات في الصين, consider:
- Quality Certifications: Ensure the manufacturer adheres to ISO, م, or API standards.
- خيارات التخصيص: Many manufacturers provide tailored solutions for specific industrial needs.
- التسعير التنافسي: Chinese manufacturers offer globally competitive prices without compromising quality.
ال DN200 butterfly valve is a versatile component used across multiple industries for effective flow control. Understanding its specifications and comparing it with larger sizes like DN800 butterfly valve و DN2000 butterfly valve helps in selecting the right valve for your application. If you’re sourcing valves, working with a reliable China valve manuFacturer ensures quality, affordability, and customization for your needs.
