硬碰硬旋球阀产品概述与用途
ZXQF3247HR硬碰硬旋球阀是上海明精阀门有限公司多年来在阀门设计制造、使用维护的经验积累上根据市场需求开发出来的双向流硬碰硬旋球阀产品。该阀不但能在正向压力下可靠地截断,在反向压力或反向压力远大于正向压力时同样能可靠地密封。该阀密封采用半球阀的结构和原理,外形采用蝶式结构,从而具有:体积小、重量轻的特征;并具有:双向硬密封、密封摩擦小、经久耐用、启闭轻便等性能,因此,性价比远高于半球阀。该阀门的成功开发与运用,是阀门行业的一次重大技术革新。双向流硬碰硬旋球阀广泛应用于水泵出口端、管网系统、回收水系统、高位水槽、易水淹的污水系统、防倒流系统等需双向密封的场合,可用于冶金、矿山、石化、化工、电力、环保、市政等行业作为管路启闭和调节使用。在双向流系统中该阀门一台相当于两台普通单向密封阀门。
主要类型和工作原理
1、主要类型:本阀门的主要类型有:蜗轮蜗杆、电动、气动、液动、其中气动阀门和液动阀门适合于有压力气源和压力液源的场合。
2、工作作原理:阀芯的密封面为三次曲面,阀座的密封面为1次圆锥面。在密封点处,阀座面实际上是阀芯三次曲面的切面(见图),因而其结合十分。有适应(中心自动定位重合)和补偿磨损功能因为转动中心偏离阀芯几何中心就有阀芯打开时阀芯实体不断向后退、向内缩、阀芯关闭时阀芯实体不断前进、向外胀的实际效果,其功能相当于半球阀、闸阀、截止阀、蝶阀的综合。打开各不同角度变化图:双向流阀门的主要功能是既能在正向压力时密封良好,在反向压力或反向压力大于正向压力时也能密封良好。当正向压力作用时,介质压力推动阀板向前移动,阀杆变形,阀板密封面紧贴阀座密封面传递压力,将阀座推向阀体台阶,使之密封良好。当反向压力作用时,介质压力推动阀板向后移动,阀杆变形,介质压力同时推动阀座密封面紧贴阀板密封面传递压力,将阀座推向阀杆极限变形位置,使之密封良好。
