How Does a Solenoid Valve Operate?
Have you ever thought of how the engine of your car starts once the key is turned? Or the way the doorbell rings when the button is pressed? How the irrigation system turns on in your lawn? The simple daily occurrences take place due to a small coil of wire that is used in the form of an electromagnet. It is called the solenoid valve. It is a component which converts electrical energy into mechanical, thus producing a magnetic reaction. It happens whenever the current runs through the wire.
The solenoid appears in the shape of a corkscrew with an iron piston casing. The device works in the form of a plunger, activating a device when it is in motion. Once simulated, the device is switched on with the magnetic field pulling the armature, irrespective of the pivot or plunger, against the action of the spring. If the activation ceases, the plunger or the pivoted armature gets back to the original position from its coil. These valves have multiple uses – like activating a fluid or hydraulic capacitated system. The valves are also used for powering or operating the central heating in homes, dishwashers and other systems or appliances that are powered by fluid or gas.
The main utility of the valves is to expel, mix or turn off gases or fluids for creating power within these systems or devices. The sixes of these valves tend to vary especially in the amount of the outlet port connections which they have. A few have a couple of ports whereas the rest contain multiple ports. Those with 2 ports are used for switching a system or device on or off. Valves with multiple ports help in switching the control in current between the various ports of the outlet. Other than different kinds of port connections, there are direct acting valves and the externally or internally piloted valves.
All sorts of these valves have functions that are similar to one another, but their scales or levels of performance might tend to vary. Direct acting valves activate the electric current in the valve which again pulls a plunger or a piston which would have otherwise blocked the fluid or air from flowing in. The case in a few valves is that the electromagnetic field will not directly act for opening the conduit. In valves that are pilot operated, the solenoids move the plunger that creates a minor opening. The valve seal is operated through the pressure in the opening. If the current is halted, the electromagnetic field will disperse and the valve will close.
