Hard sealed high-temperature triple eccentric butterfly valve VOCS tail gas butterfly valve with zero leakageShanghai Fadeng/VTTEN
1、 The RTO triple eccentric zero leakage butterfly valve is designed as a flange type; Especially adopting a rear seat ventilation structure, there is no jamming phenomenon under low or high temperature conditions; It has the advantages of flexible opening and closing, and automatic sealing compensation with trace elasticity. Faden RTO triple eccentric zero leakage butterfly valve is suitable for regulating gas flow in environmental RTO and pipeline systems for air volume regulation and environmental protection in industries such as chemical, power plant, metallurgy, cement, etc.
2、 Main performance specifications:
1. nominal diameter: DN (mm) 50-3000
2. Nominal pressure: PN (Mpa) 0.05-0.3
3. Strength test pressure: PS (Mpa) PN x 1.5 times
4. Applicable temperature: t (° C) ≤ 650
5. Leakage rate: 0 leakage
6. Applicable media: exhaust gas, air; Dust gas; Harmful gases such as cold and hot
7. Medium flow direction: in any direction
8. Control form of medium: fully open Fully closed and 0-90? Adjust arbitrarily within the range
3、 Characteristics and standards:
1. This valve is welded with high-quality steel plates, which are small and lightweight, easy to decorate. The double design of the fitting part enhances its firmness.
2. Due to the vertical structure of the butterfly plate, the overcurrent area is large, the flow resistance is small, the switch is flexible, the operation is convenient, and it saves time and effort
3. Welding data: According to GB/T12224-2005 and GB/T19866-2005.
4. Drive device standards: comply with JB/T8864-2004, JG/T8528-1997, GB/T12222-1989
Waiting standards.
5. Manufacturing and acceptance shall comply with QB/THQB0102-1999, GB/T26480-2011, and JB/T248-1985.
If the temperature is too high, add a heat sink component to the neck to cool down and protect the driving device.
