美标伞齿轮闸阀
采用标准:
设计制造:铸钢闸阀按照API 600(ISO 10434)、AP I600
检验和试验:API 598、API 600、API 6D
法兰连接:ASME B16.5(NPS≤24)、API 605、ASME B16.47 A系列、MSS SP-44(NPS>24)
对焊端:ASME B16.25
承插焊端:ASME B16.11
结构长度:ASME B16.10
温压等级:ASME B16.34
闸阀优点
闸阀用于截断或接通管路中介质的流向,它具有流体阻力小,开闭较省力,介质流向不受限制,不扰流、不降低压力,结构长度短,制造工艺性好,适用范围广的优点。 |

阀盖垫片形式:
Class150 闸阀采用不锈钢石墨复合垫片;Class300闸阀采用不锈钢石墨缠绕垫片;Class600闸阀可用不锈钢石墨缠绕垫片也可采用金属环垫片;Class900闸阀可采用金属环垫片;Class1500~Class2500闸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。
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。
弹簧加载填料冲击系统:
如果客户要求,可采用弹簧加载填料冲击系统提高填料密封的持久性和可靠性。
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。
