摘　　要：该文以典型的喷嘴挡板式电液压力伺服阀为例,介绍了电液压力伺服阀的工作原理及过程,从温度影响喷嘴、节流孔、磁性能、滑阀以及油液等几个方面,分析了电液压力伺服阀因温度变化从而引起输出压力发生变化的原因,并提出了减小温度零漂的措施。This paper taking the typical nozzle flapper type electro-hydraulic pressure servo valve as an example,introduces the working principle and process of the electro-hydraulic pressure servo valve and analyzes the reasons for the change of the output pressure of the electro-hydraulic pressure servo valve due to the change of the temperature from the aspects of the temperature affecting the nozzle,the orifice,the magnetic properties,the slide valve and the oil,and puts forward the measures to reduce the temperature zero drift.
