Three Eccentric Multi-level Hard Seal Flanged Butterfly Valve


The three-eccentric multi-layer hard-sealed flanged butterfly valve is a long-life, energy-saving butterfly valve. The three-eccentric multi-layer hard-sealed flanged butterfly valve is designed with three-dimensional weaving principle. The valve seat adopts a multi-layered structure that is compatible with hard and soft seals. The machining is superb and the technology is advanced. The three eccentric multi-level hard seal flanged butterfly valve. 
  
Features:Three eccentric multi-layer hard seal flanged butterfly valve series products are long-life, energy-saving butterfly valves. Its structure is designed with three-dimensional weaving principle, and the valve seat adopts a multi-layered structure that is compatible with hard and soft seals. It has superb processing and advanced technology. The three eccentric multi-layer hard seal flanged butterfly valve products consist of valve body, butterfly plate, multi-seat valve seat, stem, transmission mechanism and other major components. The three-eccentric multi-layer hard-sealed flanged butterfly valve is therefore widely used in pipelines of corrosive media such as metallurgy, electric power, petroleum, chemical industry, air, coal gas, combustible gas, and water supply and drainage. 
 
One, three eccentric multi-level hard seal flange butterfly valve features 
 
The three-eccentric multi-level hard-sealed flanged butterfly valve adopts the principle of three-dimensional eccentricity, so that the space motion trajectory of the sealing surface is idealized, the sealing surfaces have no friction, no interference, and the sealing material is properly selected, so that the three eccentricities are more The sealing, corrosion resistance, high temperature resistance and wear resistance of the level hard-seal flanged butterfly valve are reliably guaranteed. 
 
Its main features are as follows: 
 
1, the opening torque is small, flexible and convenient, saving energy. 
 
2. The three-dimensionally braided structure makes the butterfly plate more tighter and tighter, and its sealing performance is reliable, achieving no leakage. 
 
3, high pressure, corrosion resistance, wear resistance, long service life. 
 
Second, three eccentric multi-level hard seal flange butterfly valve principle 
1. Deviation from the center of the pipe: When the valve is opened, the butterfly plate and the valve seat come into instant contact when they are closed, using the eccentricity of the butterfly plate. 
2. Deviation from the center of the sealing surface: Quickly disengaging from the valve seat, reducing wear of the sealing pair, small friction torque, and flexible opening. Eccentric cone 
3, inclined cone: so that when the valve is opened or closed, the butterfly plate can pass through the inner hole of the valve seat to achieve contact sealing. In addition, the radius of rotation of the conical disc is greater than the radius of rotation of the contact position of the sealing pair, so that the butterfly plate will appear tighter and tighter when the valve is closed, and self-locking can be achieved to prevent the disc from over-positioning
