氣動三偏心(xīn)硬密封蝶閥是(shì)在二偏心硬密(mì)封蝶閥基礎上(shang)生成一 個角度(dù)(密封面為斜錐(zhuī)面)，從而形成三(san)偏心硬密封蝶(dié)閥。該結構 在啟(qǐ)閉過程中無機(jī)械磨損和💛擦傷(shāng)，其關閉力矩小(xiǎo)、切斷性能好、 使(shǐ)用壽命🆚長，同時(shi)具有調節和切(qie)斷兩種功能。 本(běn)系列産品廣泛(fan)應用于石油、化(hua)工、電力、冶金、環(huán)保、輕 紡、造紙等(děng)工業部門的自(zì)動化控制系統(tǒng)中👣。适用于液體(tǐ)、氣體、 煤氣、天然(rán)氣、蒸汽等介質(zhì)進行截止或調(diào)節流量控制。 

The pneumatic tri-eccentric hard seal butterfly valve is based on the two-eccentric hard seal butterfly valve to generate an angle(the sealing surface is an inclined cone) ， thus forming the tri-eccentric hard seal butterfly valve.The structure has no mechanical wear and scratch in the process of opening and closing， small closing torque， good cutting performance and long service life， as well as has two functions of adjustment and cutting. This series of products are widely used in the automatic control system of petroleum， chemical industry， electric power， metallurgy， environmental protection， light textile， papermaking and other industrial sectors. In addition， it's suitable for liquid， gas， coal gas， natural gas and steam to cut of for regulate flowcontrol.
