氣動三(sān)偏心硬密(mì)封蝶閥是(shì)在二偏心(xin)硬密封蝶(dié)閥基礎上(shàng)生成一 個(ge)角度(密封(feng)面為斜錐(zhui)面)，從而形(xíng)成三偏心(xīn)硬密封蝶(die)閥⭐。該結構(gou) 在啟閉過(guo)程中無機(ji)械磨損和(hé)擦傷，其關(guan)閉力矩小(xiǎo)、切🤩斷性能(néng)好、 使用壽(shòu)命長，同時(shí)具有調節(jie)和切斷兩(liang)種功能。 本(běn)系列産品(pǐn)廣泛應用(yong)于石✂️油、化(hua)工、電力、冶(yě)金、環保、輕(qing) 紡、造紙等(deng)工業部門(men)的自動化(huà)控制系統(tǒng)中。适用于(yú)液體、氣體(tǐ)、 煤氣、天然(rán)氣、蒸汽等(deng)介質進行(háng)截止或調(diào)節流量控(kong)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.
