氣動(dong)三偏心硬密封蝶(dié)閥是在二偏心硬(ying)密封蝶閥基礎上(shàng)生🧑🏽‍🤝‍🧑🏻成一 個角度(密(mì)封面為斜錐面)，從(cóng)而形成三偏心硬(ying)密封蝶閥。該結構(gòu) 在啟閉過程中無(wu)機械磨損和擦傷(shāng)，其關閉力矩小、切(qiē)斷性能💚好、 使用壽(shòu)命長，同時具👨‍❤️‍👨有調(diao)節和切斷兩種功(gōng)能。 本系列産品廣(guǎng)💚泛應用于石油、化(huà)工、電力、冶金、環保(bao)、輕 紡、造紙等工業(yè)部門的自動化控(kong)制系統中。适用于(yu)液體、氣體、 煤氣、天(tiān)然氣、蒸汽等介質(zhì)進行截止或調節(jie)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.
