射流偏转板射流口堵塞时可失效对中,但偏转板完全偏向一侧时无法失效对中.该文针对单级射流偏转板伺服阀该故障模式,分析了一种解决方法,并用FLUENT对射流板不同位移进行流体仿真和建模分析.

When a deflector servovalve's jet-orifice is blocked, it can be fail-mid automatic. But If the deflector entirely move to one side, the fail-midfunction does not work. To this mode failure of single-stage deflector servo valve, weanalysis a solution, simulate it by fluent in different displacements and model it withsimulation results.
