Product Name:
Q941F-16P Electric flanged ball valve
Description:

电动法兰球阀 Q941F

用  途
电动球阀是一种转角为90°的旋转类球阀,密封性能优良,流通能力大,流阻系数小,结构简单、维修方便、使用寿命长,阀体通道和连接管径相等并成一直径,介质几乎可以毫无损失的流过。配用DKJ-Ⅱ、Ⅲ执行器引配日本工装、西德欧姆龙等高性能执行机构。产品通常用于密封要求严格的场合,除控制气体、液体、蒸汽介质外,还适宜控制污水和含有纤维性杂质的介质,广泛用于石油、化工、冶金、轻工、造纸、电站、制冷等工作领域。
球阀是一种重要的阀类,在石油化工、长输管线等领域有广泛应用。球阀的关闭件是一个带孔的球体(或部分球),球体随阀杆转动,实现阀门的开启或关闭。
球阀旋转90°即可全关全开,与相同规格的闸阀、截止阀比较、球阀体积小、重量轻,便于管道安装。
