The solenoid valve is an important component in most engineering devices. Let's explore the impressive technique behind solenoid valves starting with the simplest. This hydraulic excavator has a very attractive solenoid valve at the heart of its operation the solenoid valve is so important that a small area on the disc can cause the excavator to jam and cause it to fail, bus solenoids used in sensor faucets other major industrial applications solenoid valves are illustrated here, now the interesting question
Some of the commonly used motorized cards in industry are shown here they work flawlessly then why do we need a solenoid valve, the answer is because the solenoid valve is very fast a normal motorized card takes one second to operate hand over the solenoid valve finishes its job in 0.03 seconds, Let's take a look at the impressive engineering behind solenoid valves starting from the simplest, let's look at the simplest solenoid valve construction.
First keep the iron matur perpendicular to the pipe, the armathur is free to move as shown, attach the electromagnet around the armathur and also attach the spring at the top of the armathur, the spring is compressed and always try to prevent the formation at the bottom, when we energize the electromagnet magnetic field a strong force will be generated around it, the armature will experience a force that causes it to move up and is perfectly parallel to the center of the coil.
The valve is now open and water flows when the coil is not energized the compressed spring will immediately close the valve, with this design we have achieved a simple jubaidi solenoid valve, called two by two because of the on and off operating state, and the basic design of our solenoid valve is ready to control some fluid flow, but there is a small problem because the fluid pressure in the formative state can bend resulting in fluid leakage, let's make some design modifications to make it more practical.
First we can move the coil and the armature a little more upwards and instead add a solid thick barrier in the flow path, now the valve is closed and liquid will not be able to pass through this area, this design will ensure that the maturing area is not bent due to water pressure, when the coil energizes the mature area will move up and the valve opens now allowing the liquid to flow easily through the gap.
Although this design prevents fluid leakage this design has another minor drawback, the problem here is that when in a state of pressure the fluid can push up to mature, this means the design will fail in the valve state if a clearly high fluid pressure is an undesired state, the technicians bring the perfect solution.
Just keeping the fluid pressure the same on both sides of the armathur let's see how this new design is done practically, the design engineers used a flexible rubber diaphragm with two holes, this diaphragm is DC group with valve body closed valve condition as shown small red hole on diaphragm plays a major role here you can see how the liquid reaches both sides of the maturing area due to this hole.
This means that when the valve is closed the pressure of the working fluid is properly reversed this completely solves the previous problem, when the coil is energized the mature ares will move up and the fluid will exit through the center hole, but this is not how the valve works the same way when the formation is increased. , here the fluid in the formation area exits and causes a sudden drop in pressure this pressure drop because the outflow through the center hole is higher than the inflow.
This pressure difference will bend the diaphragm as shown, now the liquid can exit directly through the bottom of the diaphragm that's how we are now designing a fast and efficient green robe solenoid valve, now let's take a look at the very popular design of the faisal basri solenoid valve, let's imagine rising excavator this.
The ballet rotates thanks to the five by three solenoid valve it is clear from this animation that when the piston of this double acting cylinder moves linearly the rotating part, by passing the pressurized oil because as shown here the piston achieves expansion movement, on the other hand the piston is ejected through pipe B because it does not can be used, well if you want to move the piston backwards the pressurized oil must enter through pipe B this causes the oil on the other side to come out of the pipe.
How can we develop technology for the oil club so that nothing will be wasted from the system, the solution is the use of an advisory solenoid valve we need a storage tank by also, the valve has fifty wills connected with this arrangement as shown k
