D41X / F Manual Flange Butterfly Valve
Description:

法兰型蝶阀

法兰型蝶阀,主要适用于水厂、电厂、钢厂冶炼、造纸,化工、饮食等系统供排水用,尤为适用自来水管道路上作为调节流量设备使用。
法兰型蝶阀特点: 
1、结构长度短、重量轻、安装方便。2、采用蜗轮传动,扭矩小、启闭灵活。3、合理的蝶板结构,流阻小,有可靠的密封性能。4、采用了LBP型自润滑轴套,大幅度提高了其面压强度和自身润滑性能。5、可任意方向安装,无定向密封限制。6、不用全部拆开阀门就可更换密封圈。7、立、卧安装均可,使用方便。 
软密封蝶阀技术参数:1、公称压力(PN)1.0Mpa(1.6Mpa)。2、强度试验压力为:PNXl.5。3、密封试验压力为:PNXl.1。 
法兰型蝶阀概述 
法兰型软密封蝶阀是管线优先选用的常规蝶阀,具有结构简洁,流阻系数小,流量特性趋于直线,不会滞留杂物。且重量轻,安装方便,驱动扭矩较小的优点。这种阀门既可作切断介质用,又可作调节介质的流量用。驱动配置根据用户要求,分别可采用手动、电动、气动等方式。选用不同材料的零件,配用不同材料的密封圈,可适应不同的介质、工况,使成本与性能达到最佳效果。 
软密封蝶阀适用于温度≤120℃或≤150℃,公称压力≤1.6Mpa给排水、污水、食品、供暖、燃气、船舶、水电、冶金、能源系统以及轻纺等行业,特别适用于双向密封和阀体易锈蚀场合,作调节流量和截流介质。
