全通径偏心半球阀详细说明:
BQ947X/F/H电动全通径偏心半球阀(DYQ947X/F/H全通径上装式偏心半球阀)是一种新型阀门,它通过转动蜗轮(手动或电动)机构,带动偏心半球转动,从而实现阀门的启闭。材质为球墨铸铁、铸钢、碳钢、不锈钢等。全通径偏心半球阀是为解决溶液及矿浆等两相流介质输送中的技术难题而研制开发的新型产品,本产品填补了国内阀门品种的一项空白的国产化系列产品,其结构上采用了偏心—楔紧原理,通过传动机构达到闸紧,调节,启闭的作用。本产品结构新颖,性能稳定,开启迅速轻便,磨损自动补偿,密封可靠耐用,易于调整维修;直通式结构流通面积大,较截止阀、蝶阀等阀门阻尼小,系统降压小;能够自行破除结垢,方便启闭,无 "死区 ",克服了闸阀、球阀、截止阀等易结疤,易堵塞、易泄漏、寿命短等弊端,显示了独有的优越性。双偏心式半球阀系列产品,贯彻了国家标准GB9113、8-11-88尺寸系列法兰连接,便于安装及替代现有阀门品种,亦可根据用户需要的连接尺寸系列安排生产,适应不同工矿条件下的需要。流阻小,密封可靠,性能稳定。被广泛应用于市政污水处理、供水及其它流体控制系统。
全通径偏心半球阀特点:
1.水损为零。采用偏心结构,阀门开启后,流道完全畅通,水头损失为零。可节约大量能源。
2.可靠的密封方式。软密封结构具有自密封性能,硬密封结构具有弹性补偿性能。
3.耐磨损,使用寿命长。球阀在开启后,球冠偏置于阀体内,不被介质直接冲刷。
4.自动清污功能。硬密封偏心半球阀的球冠边沿采用刀刃状,不但可以刮去阀座上的污垢,还可以切断杂物。
5.启闭迅速。偏心曲轴旋转90度即可实现启闭,启闭时间短。
6.适合高流速。直通流道,坚固的偏心曲轴使之适用高流速且无振动。
7.适用介质:清水.原水(含泥沙).污水.海水、蒸汽、煤气、天然气、油品等。
8.适用温度:软密封偏心半球阀为-40℃-135℃;硬密封半球阀为常温至600℃左右。
9.适用压力:PN6-PN40。
10.公称通经:DN50~DN1600。
