不锈钢偏心半球阀是用于喷煤粉、控制法气体、含颗粒流体及粉沫固体介质输送的*设备,应用于冶金、选矿生产的煤粉喷吹阀。
特点:
1、直通型、单向密封、偏心式结构,特别用于煤粉喷吹的气固两相流介质,无阻挡流道贯通、不会出现积灰或卡死的现象。
2、开关轻便,开启时球与壳体脱离,无任何接触,启动扭矩小,转动灵活。关闭时,半球与阀座的挤切作用能除去密封面上的污物,密封严紧可靠。
3、密封面的偏心结构,使球面能自动补偿磨损,能保持阀门的密封,使用寿命长。
4、该阀门T型是属于耐磨硬密封球阀,它的密封副材料是特殊的,密封面要经过特殊耐磨处理。处理后表面硬度可达到HRC65-72度,故阀门的耐磨性能特别好。
5、阀门表面油漆,有常温和高温两种。高温用耐温600℃的进口漆,喷涂后,高温使用不烧漆、炭化、焦化现象、不变色。
