氣動三偏心硬密封蝶(dié)閥是在二偏心硬密封蝶閥基礎(chǔ)上生成一 個(gè)角度(密封面為斜錐面)，從而形成三偏心硬密封(fēng)蝶閥。該結(jié)構 在啟閉過程中無機械磨損(sǔn)和擦(cā)傷，其(qí)關閉力矩小、切斷性能好(hǎo)、 使用壽命長，同時具有調節和切斷兩種(zhǒng)功能。 本系列産品廣泛應用于石油、化工(gōng)、電力、冶金、環保、輕 紡、造紙等工業(yè)部門的自動化控制系統中。适用(yòng)于液體、氣(qì)體、 煤氣、天然(rán)氣、蒸汽等介質進行截止或調節流量控制。 

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.
