美标截止阀
美标截止阀
公称通径:DN50-DN400,
压力等级:150LBS~1500LBS,
材质:WCB,WCC,LCB,LCC,WC6,WC9,CF8,CF8M等
截止阀是在管道中用来调节流量的阀门,不仅开闭过程中密封面之间摩擦力小,比较耐用,而且结构简单,制造容易,维修方便.
采用标准:
设计制造:铸钢截止阀按照BS 1873 and ASME B16.34
检验和试验:API 598
法兰连接:ASME B16.5
对焊端:ASME B16.25
结构长度:ASME B16.10
温压等级:ASME B16.34
操作形式:
一般情况下采用手轮驱动或者齿轮传动方法,可根据用户需要采用链轮传动或者电动装置。 |
|
阀体和阀盖连接形式:
Class150~Class900采用拴接阀盖;Class1500~Class2500采用自压密封式阀盖。
阀盖垫片形式:
Class150截止阀采用不锈钢石墨复合垫片;Class300截止阀采用不锈钢石墨缠绕垫片;Class600截止阀可用不锈钢石墨缠绕垫片也可采用金属环垫片;Class900截止阀可采用金属环垫片;Class1500~Class2500截止阀采用自密封金属环。
填料密封:
通常采用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3.2μm,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0.8μm可以保证阀杆可靠的密封。
截止阀结构特点:
拴接阀盖,明杆支架和升降式阀杆金属密封面。
