Unbalanced force suffered from the spool of view, the valve core regulatory agencies are two types of imbalance and balance.

从阀芯所受不平衡力看，调节机构的阀芯有不平衡和平衡两种类型。

Reverse angle valve is intended to improve Safety valves the use of unbalanced force and reduce the wear on the spool, but also conducive to high-viscosity, easy to medium coke and flow with suspended particles, to avoid coking and blocking.

角型调节阀反向使用的目的是为了改善不平衡力和减少对阀芯的磨损，同时也有利于高粘度、易结焦和含悬浮颗粒物介质的流动，避免结焦和堵塞。

Numerical simulations were done for a bistable latch valve of the system by FLUENT, and three groups of datum for different fluids were obtained with the same effective exit sectional area. Besides, a static mathematic model for the electromagnetic valve was established based on the obtained datum. Secondly, the motion of the valve spool was realized by UDF file in FLUENT. Three kinds of motions, uniform, acceleration and motion driven by the coupling effect of the liquid resistance and the electromagnetic force, were calculated and compared. The dynamic characteristic of the electromagnetic valve was obtained by analyzing the relationship of the mass flow rate of the inside flow field of the electromagnetic valve, the change of the drop pressure of the passageway of the valve, and motion time.

并针对系统中的某双稳态电磁阀，使用商用CFD软件FLUENT对其进行内部流场的数值模拟，通过使用不同流体介质，不改变阀门有效出口截面积的情况下，分析得到的三组数据，建立了该电磁阀的静态数学模型；通过编写UDF文件，实现对阀芯运动方程的控制，在阀门做由闭合到开启、开启到闭合运动时，控制阀芯分别做匀速运动、匀加速运动以及阀芯受到液体阻力与电磁力作用力的耦合力的运动，分析了三种工况下电磁阀内部流场质量流率和阀门出口入口压降的变化以及运动时间，从而得到该电磁阀的动态特性。
