结构设计、特点及用途
1.阀体和阀盖连接形式:PN10-64采用栓接阀盖;PN64-320采用自压密封式阀盖。
2.阀杆螺母:通常情况下,阀杆螺母材料采用ASTM A439 D2,同时可以根据用户要求采用铜合金等材料,对于大口径的截止阀,装滚动轴承,可以X减小截止阀的开启力矩使阀门可以轻松开关。
3.阀杆设计:采用整体锻造工艺制成,按照标准要求确定X小直径。
阀盖垫片形式:PN10-64截止阀采用不锈钢石墨缠绕垫片;PN100截止阀可用不锈钢石墨缠绕垫片也可采用金属环垫片;PN160截止阀可采用金属环垫片,PN320截止阀采用自压密封金属环。
4.截止阀结构特点:栓接阀盖,明杆支架和升降式阀杆金属封面。
5.上密封座设计:我公司提供的所有截止阀都有倒密封设计,通常情况下,碳钢截止阀的阀座设计采用分离式倒密封结构,不锈钢截止阀的倒密封面非常可靠。虽然按照标准API600中有倒密封,但这不作为在带压情况下更换填料的依据。
6.填料密封:通常采用成型柔性石墨作为填料材料,可根据用户需求提供PTFE或者复合填料材料。填料与填料函接触的表面粗糙度为3.2u m,可以保证阀杆与填料接触面接合紧密但是旋转自如,经过精密的机械加工的阀杆密封面粗糙度0.8u m可以保证阀杆可靠的密封。
7.阀座:碳钢截止阀阀座通常采用锻钢材料,阀座密封面可根据客户需求喷焊硬质合金,NPS≤10″的截止采用分离式螺纹旋入式阀座,如果用户需要焊阀座结构也可提供;NPS≤12″截止阀采用焊阀座结构;不锈钢截止阀的阀座一般采用整体式或者在本体上焊硬质合金后直接加工阀座。如果用户有需求,不锈钢截止阀阀座也可采用分离式螺纹旋入式和焊接阀座结构。
