酞阳节流阀NCEB-LCN-GBZ产品广泛应用于钢铁、冶金、石油化工、航天、船舶制造、煤炭、水泥、电力、汽车、工程机械、食品、林业、纺织、皮革、造纸等行业领域

节流阀是通过改变节流截面或节流长度以控制流体流量的阀门。将节流阀和单向阀并联则可组合成单向节流阀。节流阀和单向节流阀是简易的流量控制阀，在定量泵液压系统中，节流阀和溢流阀配合，可组成三种节流调速系统，即进油路节流调速系统、回油路节流调速系统和旁路节流调速系统。节流阀没有流量负反馈功能，不能补偿由负载变化所造成的速度不稳定，一般仅用于负载变化不大或对速度稳定性要求不高的场合

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jian角为140180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。由于节流阀的流量不仅取决于节流口面积的大小，还与节流口前后的压差有关，阀的刚度小，

故只适用于执行元件负载变化很小且速度稳定性要求不高的场合。

对于执行元件负载变化大及对速度稳定性要求高的节流调速系统

，必须对节流阀进行压力补偿来保持节流阀前后压差不变，从而达到流量稳定

节流阀的安装与维护应注意以下事项：

该阀经常需要操作，因此应安装在易于方便操作的位置上。

安装时要注意介质方向与阀体所标箭头方向保持一致。

美国酞阳：SUN公司插式阀结构，提供超群的性能。其阀尾端的自由浮动，籍此其紧密配合的工作组件，可在阀体内浮动减少其多安装扭矩的敏感度以及避免其内部活动组件卡住的可能。流量大，压损低，空间效益 化。其组件均经热处理加工耐磨，耐撞击，抗疲劳，使用寿命长。

SUN提供国内各界先进的油压插式阀与成套的油压阀组.流量由1 L/min. 到 720 L/min. 压力可达42 MPa, 品质保证, 设计精良, 交期迅速, 适用于工业生产设备, 工程车辆, 船舶, 输配电设备以及各种油压机械。
