利用三個偏心的結(jié)構(gòu)，使閥門啟閉時閥板與閥座間幾乎沒有庫擦，杜絕了普通閥門打開時所 出現(xiàn)的跳躍現(xiàn)象，從。度開始即進(jìn)入可調(diào)區(qū)域，直至90度全開，其正?？烧{(diào)比是普通蝶閥的2倍以 上，可調(diào)比■高可達(dá)100:1,這為偏心蝶閥作為調(diào)控閥使創(chuàng)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.
