D643H气动多层次法兰金属硬密封蝶阀
严格按照国家GB/T13927-92阀门压力试验标准生产。
采用精密弹性密封圈和三偏心多层次金属硬密封结构,使阀座与碟板密封面均采用不同硬度和不锈钢制作,具有良好的耐腐蚀性,使用寿命长,本阀均有双向密封功能,气动多层次硬密封蝶阀广泛用于
介质温度≤425℃的治金、电力、石油化工、以及给排水和市政建设等工业管道上,作调节流量和载断流体使用。
D643H气动多层次法兰金属硬密封蝶阀性能特点:
1,采用三偏心密封结构,阀座与蝶板几乎无磨损,具有越观越紧的密封功能。
2,密封圈选用不锈钢制作,具有金属硬密封和弹性密封的双重优点,无论在低温和高温的情况下,均具有优良的密封性能,具有耐腐蚀,使用寿命长等特点。
3,碟板密封面采用堆焊钴基硬质合金,密封面耐磨损,使用寿命长.大规格蝶板采用绗架结构,强度高,过流面积大,流阻小。
4,D643H气动多层次硬密封蝶阀具有双向密封功能,安装时不受介质流向的限制,也不受空间位置的影响,可在任何方向安装。气动驱动装置可多工位安装,方便使用。
