結(jié)構(gòu)特點(diǎn)及用途:
二片式氣動(dòng)高平臺(tái)法蘭球閥具有旋轉(zhuǎn) 90 度的動(dòng)作,旋塞體為球體,有圓形通孔或通道通過其軸線。球閥在管路中主要用來做切斷、分配和改變介質(zhì)的流動(dòng)方向,它只需要用旋轉(zhuǎn) 90 度的操作和很小的轉(zhuǎn)動(dòng)力矩就能關(guān)閉嚴(yán)密。球閥宜做開關(guān)、切斷閥使用。
重要特點(diǎn):
◎ 2片式浮動(dòng)球閥
◎ 防吹出,防靜電閥桿
◎ ISO5211 直裝平臺(tái)
◎ PN25-PN40,150LB,300LB 標(biāo)準(zhǔn)
◎ 自適應(yīng)密封結(jié)構(gòu)設(shè)計(jì)
◎ 帶防火設(shè)計(jì) ( 定制 )
