PQ340F、PQ340H上装偏心半球阀
偏心式半球阀是一种新型阀门,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*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*的*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。

结构特点及用途
1、 电动偏心半球阀压力损失小:全开时水损为零,流道*畅通,且介质不会沉积在阀体中腔内。
2、 耐颗粒磨损:V型开口的球冠与金属阀座之间具有剪切作用,在关闭过程中,只在zui后一刻球冠才靠向阀座,不形成磨擦,且阀座耐磨的镍合金制成,不易被冲刷磨损,因而适用于含纤维、微小固体颗粒、浆等。
3、 适合高流速介质:直通流道,坚固的偏心一曲轴使之适合高流速且无振动。
4、 寿命长:无易损部件,由于偏心作用,阀门启闭时密封面间无磨擦,则使用寿命长。
5、 维修方便:阀门维修时不需从管路上拆下,只要打开阀盖即可进行维修
6、 气动偏心半球阀广泛适用于水、污水、含微小固体颗粒、水、蒸汽、煤气、天然气、油品等。
Structural characteristics and uses
1、 little pressure loss: water loss is zero at full open, compley smooth flow, which will not be deposited on dielectric Valve cavity.
2、 Bears the particles attrition: V shape opens the mouth between the ball crown and the metal valve seat the action is shear, in the closure process, only then depends on in last the moment ball crown to the valve seat, does not form the friction, also the valve seat makes with the wear-resisting nickel alloy, is not easily washed out the attrition, thus is suitable to contains the textile fiber, the small solid particle, the thick liquid and so on.
3、 Suitable for high-velocity media: Direct flow, solid eccentric crank ,make it suitable for high speed without vibration.
4、 Long life: no vulnerable parts, there is no friction between the sealing surface when the valve opens and close due to the function of the eccentric, therefore there is long life.
5、 Easy maintenance: Valve repair without remove from the pipeline, as long as the valve cover is opened for maintenance.
6、 Widely used in water, sewage, containing tiny solid particles, water, steam, gas, oil, etc.
