Automotive solenoid valve function, extremely working principle
Automotive solenoid valve : Principle: when energized, the electromagnetic coil generates electromagnetic force to lift off the closing part from the seat and the valve opens; When the power is off, the electromagnetic force disappears, the spring closes the closing piece on the seat and the valve closes. Role: Automotive solenoid valve is the use of electricity flows through the coil will generate electromagnetic suction valve core (or overcome spring since the gravity). Normally open and normally closed two kinds. Commonly used to cut off the oil, water, gas and other material circulation. Cooperate with pressure, temperature sensors and other electrical equipment to achieve automatic control. Features: normal working in vacuum, negative pressure and zero pressure, but generally not more than 25mm.
