The instantaneous opening of the vent valve in the opening process is large and the spool movement is affected by the stop device.

排油阀开启过程瞬时开度大且阀芯运动受限位装置影响。

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。

Because of this torque balance, ensure the valve opening and the corresponding relationship between the input signal accurately to achieve the correct positioning of the spool.

水力控制阀由于这种力矩平衡，保证了调节阀开度与输人信号之间对应关系准确，实现了阀芯正确定位。
