At present, hydraulic valve has the deficiency of inadequate interchangeability and machining difficulty of unsymmetrical valve spool.
目前，液压阀存在互换性差、不对称阀芯的设计加工困难等不足。
Spool valve is composed of valve spool and valve sleeve, and as the power stage of servo valve, it has a high degree of accuracy and is difficult for machining.
滑阀是由阀芯和阀套两部分组成，通常用作电液伺服阀的功率放大级，其精度要求高，加工难度大。
It can be concluded that cavitation of hydraulic cartridge cone valve is reduced by increasing the opening stroke and the outlet pressure and changing the geometrical structure of valve spool.
研究表明：增大阀口开度，增大出口压力，并对阀芯结构进行修改后，插装型液压锥阀阀口气穴现象均可有效减弱。
