利用三个偏心的结构，使阀门启闭时阀板与阀座间几乎没有庫擦，杜绝了普通阀门打开时所 出现的跳跃现象，从。度开始即进入可调区域，直至90度全开，其正常可调比是普通蝶阀的2倍以 上，可调比■高可达100:1,这为偏心蝶阀作为调控阀使创造了解的釧牛。
Using the three eccentric structures, there is little friction between valve plate and valve seat when the valve is open and close, which can eliminate the jumping phenomenon when the valve is opened. Adjustable range is from 0 degree to 90 degrees, and its normal adjustable ratio is 2 times more than ordinary butterfly valve, and adjustable ratio is up to 100:1.
This creates the good condition for the eccentric butterfly valve as a control valve.
