手柄衬氟球阀产品说明:
球阀是用带圆形通孔的球体作启闭件,球体随阀杆转动,以实现启闭动作的阀门。球阀在管路中主要用于切断、分配和改变介质流动方向。
手柄衬氟球阀结构特点:
1、流体阻力小,全开时球体通道、阀体通道和连接管道的截面相等,并且成直线相通,介质流过球阀相当于流过一段直通的管子,在各类阀门中球阀的液体阻力zui小。
2、启闭迅速,启闭时只需把球体转动90°,方便而迅速。
3、结构较简单,体积小、重量较轻,特别是它的高度远小于闸阀和截止阀。
4、密封性能优良可靠,零泄漏,使用寿命长。
5、两段式、三段式结构可适用各种不同要求的管路系统和工况条件,其中三段式球阀允许主阀体与两侧阀体分离,可实现在线快速更换、维修。
6、可根据用户需求配置气动、电动装置、满足遥控和程控的要求。
7、更换零件衬里材质可适用于各种介质。
