Abstract:
An integrative bi-coil high-speed solenoid valve with high technique additive was developed 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 superiority 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.
