How Does a Solenoid Valve Work?
Pressure is applied to the diaphragm with the help of spring with the iron core inside the coil, which is one of the auxiliary elements of the solenoid valve. This iron core is also called a valve piston. When the current given to the solenoid valve moves towards the inside of the coil, the current lines turn the valve piston into an electromagnet. The coil applies pressure to move the valve piston up or down according to the requirements of the situation. In this way, the fluid path is opened for fluids to enter.
The fluid inlet and outlet lines of solenoid valves are shown with an arrow on the element body. The valve connection should also be made in the same direction as this mark. The valve connections that are not made in the same direction as the arrow mark can open the valve by overcoming the spring force on the diaphragm by the fluid pressure coming from the opposite direction. Solenoid valves that are not energized are normally closed and fluid passage through them is prevented.
How does a direct-acting solenoid valve work?
The direct pull solenoid valve consists of the sleeve, core, coil, socket, and valve body. It is connected to the pipeline in the direction of the arrow sign on the valve body in the direction of the flow of the fluid. A sealing auxiliary element is added as assembled to the core to prevent the fluid from leaking. Electric current is supplied to the coil to provide flow. The coil is set in motion with the right energy.
It exerts upward pressure on the iron core in the hive. As the iron core moves up, the fluid enters. The fluid moves in the pipeline until the electric current on the coil is interrupted. When the power is cut, the coil stops pressing and the line closes.
How Does Pilot Controlled Solenoid Valve Work?
Pilot controlled solenoid valve consists of a socket, orifice knurled nut, coil, sleeve, o-ring, bolt, core, ball, cover, spring, diaphragm, and body. Such solenoid valves are called diaphragm solenoid valves. These solenoid valves have a large orifice diameter in the valve body. After the electric current specified on the pilot-controlled solenoid valves is applied, pressure is applied to the shell and the core by pressing the coil.
Fluid enters the inlet line of the valve, passes upward through the diaphragm, and exerts a thrust on the diaphragm. Orifice closes here. The element that will open the valve allows the flow to pass with the spring pressure when the energy flow is provided to the coil. When the electricity is cut, the core is released back and the input line is closed.
What is Automatic Gas Shut-Off Solenoid Valve?
Solenoid valve is also known as electric gas shut-off valves. Generally, manually operated solenoid valves are preferred for the gas line. This type of solenoid valves cut off the gas if it receives a closing signal from the central panel. The solenoid valve that cuts the gas does not give the gas even if it receives a signal from the panel to open it again.
To open the gas, the solenoid valve is opened manually either by pressing on it or by pulling upwards and gas is given. Thus, in cases such as gas leakage, it can be detected by the user. Automatic gas shut-off solenoid valves come in two types, normally open and normally closed. Normally open valve supplies to the gas input as long as there is no voltage to the coil. If it receives a signal from the panel, voltage is given and the gas closes. It is a type of solenoid valve used in normally closed gas burning systems that operate dependent on electricity.
Where Are Solenoid Valves Used?
The solenoid valve is used in all systems that need to be used as open or closed. The medium starts from the entry point of the solenoid valve. Before going to the exit point, it crosses the piston barrier and then passes through the orifice point. Then it moves towards the exit line. The main control point of this system is known as the piston. If we give examples of solenoid valves from our daily life, we can start from our home first.
Solenoid valves are widely used in water intake and discharge systems of washing and dishwashers in our homes, automatic faucets, machines such as coolers, garden irrigation systems, and thermostat control. Solenoid valves are common in industrial and daily life.
What Are The Features Of Solenoid Valve?
A solenoid valve is used to control fluid substances such as air, water, gas, or water vapor. It is useful for controlling fluids. Fluid control is provided by parts such as inlet line, outlet line, coil, cable entry, piston, spring, and orifice.
There are different types of solenoid valves. Not all solenoid valves work with the same electric current. Generally, it is written on how many voltage electric current the solenoid valves need.
