The working principle of Danfoss solenoid valve
Danfoss solenoid valve
Electromagnetic valves provide a simple way to control and regulate fluids and gases. Danfoss solenoid valves include direct acting, pilot operated, and assisted lift types. If the pollution level of the medium in the working environment is not high and the flow rate is not large, solenoid valves are the ideal choice.
working principle
The solenoid valve has a sealed chamber with through holes at different positions, each hole leading to a different oil pipe of the solenoid valve. The middle of the chamber is the valve, and there are two electromagnets on both sides. The magnetic coil on which side is energized will attract the valve body to which side. By controlling the movement of the valve body, different oil discharge holes will be blocked or leaked out. The oil inlet hole is normally open, and hydraulic oil will enter different oil discharge pipes. Then, the pressure of the oil will push the piston of the cylinder, which in turn drives the piston rod, and the piston rod drives the mechanical device to move. In this way, the mechanical motion is controlled by controlling the current on and off of the electromagnet.
