valve overlap meaning in Chinese

气阀重叠
气门叠开角
气门重叠角

During the performances of the syt - i servo valve overlap hydraulic measuring platform , the pressure difference between the exit and the entrance keeps changing , which causes comparatively great principle error in the measurement and affects the accuracy of the measuring system
在syt - i型伺服阀叠合量液动测量台进行伺服阀叠合量的测量过程中,阀入出口压力差变化给叠合量的测量带入较大原理性误差,影响了测量系统的精度。
Due to this , it is important to improve the hydraulic power system and enable it to control the pressure change at the measuring points of the servo valve , thus to develop the syt - ii servo valve overlap hydraulic measuring platform and improve the processing quality of servo valve
因而对其油源系统加以改进,使其能控制伺服阀测量口处压力变化,进而开发出高精度的恒压油源,研制出syt - ii型伺服阀叠合量液动测量台,提高伺服阀的加工制造水平。
