تعمق في السمات الرئيسية لصمامات الفراشة عالية الأداء المصممة بدقة لتلبية المتطلبات الصارمة للتطبيقات الحيوية, emphasizing reliability, precise shut-off capabilities, and enduring durability.
صمام الفراشة الختم الناعم
التصميم والتشغيل:
The valve consists of a disc, often referred to as the “فراشة,” positioned perpendicular to the flow direction. This disc is connected to a shaft, enabling rotation for flow regulation. Soft-sealing butterfly valves utilize a soft seal, typically made from rubber or elastomer, to ensure a tight shut-off and minimize the possibility of leakage.
التطبيقات:
These valves find use in various industries:
- المعالجة الكيميائية: Demonstrates exceptional resistance against corrosive fluids.
- معالجة المياه: Frequently employed to regulate water flow within treatment facilities and distribution networks.
- أنظمة التدفئة والتهوية وتكييف الهواء: Manages air and water flow within heating, تنفس, and air conditioning setups.
- الغذاء والمشروبات: Incorporates a hygienic design tailored to the requirements of the food industry.
- توليد الطاقة: Exercises control over water, بخار, and various fluids within power plant environments.
مزايا:
- فعالة من حيث التكلفة: Generally more affordable than other valve types.
- تصميم مضغوط: Lightweight and easy to install.
- عملية سريعة: Quarter-turn action enables fast opening and closing.
- Tight shut-off: Soft sealing ensures minimal leakage.
- Low maintenance: Simple design with fewer components and long service life.
When selecting a soft sealing butterfly valve, consider factors such as operating conditions, مقاس, and flow capacity to ensure optimal performance.
دouble flanged butterfly valve
التصميم والتشغيل:
The valve comprises a disc, commonly known as the “فراشة,” affixed to a valve stem. This stem extends through the valve body and links to an actuator or handle. Upon turning the actuator or handle, the disc rotates, either permitting or obstructing the flow. Its double-flanged design entails flanges welded to both the inlet and outlet ends of the valve body.
التطبيقات:
These valves are frequently employed to control, regulate, and throttle the flow in diverse applications across industries such as water treatment, المعالجة الكيميائية, وأنظمة التدفئة والتهوية وتكييف الهواء (HVAC)..
مزايا:
- Resilient Seating: The double-flanged design ensures a tight seal, making it suitable for dead-end service.
- تسهيل التثبيت: The flanges allow straightforward connection to pipelines with matching flange sizes.
يتذكر, double-flanged butterfly valves are versatile and reliable components used in fluid systems for efficient flow control.
دouble offset butterfly valve
التصميم والتشغيل:
A double-offset butterfly valve is designed with two key offsets compared to the concentric type:
- First Offset: The shaft is not centered on the disc but positioned slightly behind it. This arrangement creates a continuous sealing surface on the disc.
- Second Offset: The shaft is not aligned with the pipe centerline but is slightly to the right of the center. عندما تفتح تماما, the valve doesn’t touch the seat at all. This reduces friction compared to concentric valves and prolongs the seat’s lifetime. The 90° rotation of the disc ensures efficient flow control.
Double-offset valves are used in systems requiring higher pressure resistance.
