性能要求编辑
对节流阀的性能要求是:
·流量调节范围大,流量一压差变化平滑;
·内泄漏量小,若有外泄漏油口,外泄漏量也要小;
·调节力矩小,动作灵敏。
节流阀(Choke valve)的外形结构与截止阀并无区别,只是它们启闭件的形状有所不同。节流阀的启闭件大多为圆锥流线型,通过它改变通道截面积而达到调节流量和压力。节流阀供在压力降极大的情况下作降低介质压力之用。
介质在节流阀瓣和阀座之间流速很大,以致使这些零件表面很快损坏,即所谓气蚀现象。为了尽量减少气蚀影响,阀瓣采用耐气蚀材料(合金钢制造)并制成顶尖角为140~180的流线型圆锥体,这还能使阀瓣能有较大的开启高度,一般不推荐在小缝隙下节流。
特点编辑
1.构造较简单,便于制造和维修,成本低。
2.调节精度不高,不能作调节使用。
3.密封面易冲蚀,不能作切断介质用。
4.密封性较差。
分类编辑
节流阀按通道方式可分为直通式和角式两种;按启闭件的形状分,有针形、沟形和窗形三种。
可调节节流阀:阀针和阀芯采用硬质合金制造,产品按API6A标准设计,具有耐磨、耐冲刷性能。主要用于井口采油(气)树设备。
滑套式节流阀:阀芯采用低噪音平衡型结构,开启轻便,产品按API6A标准设计,阀芯表面覆盖碳化钨,适合于有闪蒸、高压差,高压力,空化等条件苛刻的场合,使用寿命长,流量调节精度大大提高。适用于石油,天然气,化工,炼油,水电等行业。
