湖北阿托斯单向节流阀KR-012/4现货 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。
