Abstract
The invention discloses a normally-powered-on solenoid valve for a crankshaft ventilation system. The normally-powered-on solenoid valve comprises a main component, an armature component and a valve seat which are mounted in the main component. The main component comprises a coil frame and a coil coiled on the coil frame. A housing sleeves the coil. The coil frame sleeves the armature component and the valve seat. One end of the coil frame is provided with a pipe jointing nozzle B connected to an intake chamber. A spring is arranged between the valve seat and the armature component. By adopting the normally-powered-on solenoid valve, when a vehicle engine is switched from high-speed operation to low-speed operation, the gas flow of intake manifolds is cut off, the gas flow in an engine combustion chamber is prevented from entering a catalytic converter, the temperature rising of the catalytic converter is reduced, and the vehicle operating safety risk is reduced; since an inner armature of the armature component is provided with a through hole and seal rubber, the product tightness is guaranteed when the valve is powered off and the flow is unimpeded when the valve is powered on, and performances of the product can be realized easily.
