2、采用偏心结构，密封副之间自动建立密封比压，减少密封面的摩擦，延长阀门使用寿命。
3、密封结构无机械链接，能适应较恶劣的工况。完全密封，泄漏为零。阀座抗冲刷能力强。
4、伸缩部位密封性能可靠，安装拆卸方便。
5、能适应一定量的环路错位和倾斜，管路连接不需焊接。
Soft sealing eccentric structure telescopic flange butterfly valve is a set of flange butterfly valve，expansion joint in one of the novel structure，with its good performance and trusted by the user.
This product is mainly used in waterworks，power plants，steel mills，oil and chemical industry，medicine，food，textile，paper and other system used for water supply and drainage，as the transformation of the old pipeline，maintenance and supporting the valve replacement，especially in water as a regulator and the use of closure devices.
1.Reasonable design，compact structure，90°rotation，opening and closing flexible.
2.The use of eccentric structure，the seal between the automatic seal，reducing the friction of the sealing surface，to extend the life of the valve.
3.Sealing structure without mechanical connection，can adapt to the harsh conditions.Completely sealed，leaked to zero.Strong anti flush valve seat.
4. Sealing performance is reliable，easy to install and remove.
5.Can adapt to a certain amount of pipeline dislocation and tilt，pipeline connection does not need to weld.
