给直动式电磁阀增加加速启动线圈,辅以集成控制电路,研制出一种具有较高附加值的集成控制双绕组高速电磁阀。试验表明:电磁阀最快开启时间为2.8ms,关闭时间小于2ms,具备明显的响应与结构优势。动态响应仿真分析表明:在加速线圈的作用下,电磁阀启动电流迅速上升至磁场饱和;进入维持打开模式后,磁场仍趋于饱和,维持电流高于释放电流,电磁阀仍有降耗的空间。

An integrative bi-coil high-speed solenoid valve with high technique additive was de- veloped by adding an accelerating start coil and controlling control circuit to the direct-acting solenoid valve. Experimental study shows that the fastest response time is 2.8 ms for opening and 2 ms for closing. Dispensing with exterior controlling circuit, the solenoid valve presents distinct superi- ority in response and structure. Numerical simulation shows the accelerating coil makes the starting current to rise promptly and the magnetic field saturate. When the status of the valve is in maintaining mode, magnetic field in solenoid is still keeping saturated, which indicates the maintaining current is much higher than release current and the energy consumption of valve can be reduced further more.
