安裝

3 h  P: Y0 G; l請(qǐng)勿使用法蘭密封件。蝶閥閥座密封面上有一圈密封唇可以充當(dāng)閥與法蘭之間的墊片。（刀口法蘭？還是組合墊？）

將閥門(mén)關(guān)閉后，將裝好閥板的閥門(mén)插入到法蘭之間。如果法蘭離現(xiàn)有的管路太近，應(yīng)通過(guò)一種特殊設(shè)備將管路撐開(kāi)，以便騰出安裝間隙。

注意！一旦安裝閥板錯(cuò)誤（與法蘭干涉），閥座密封圈會(huì)在第一次運(yùn)動(dòng)時(shí)位移并損壞。同樣的，如果沒(méi)有注意閥板是否能在法蘭間自由運(yùn)動(dòng)，閥板的密封圈會(huì)被損壞。
