To control the fluid flow that I am working on, my main task is to improve the system how to it performs faster and more reliably than the old valve. It is important to have a good life expectancy. In this article I will share my insights on the solenoid valve, hopefully, it will be useful for my colleagues.
Solenoid valves are one of the most popular valves, common valves at now. Therefore its application is extremely broad: in civil or industrial, etc.
Solenoid valves are an electromechanical device used to control fluid or gas flow. Solenoid valves controlled by 220V or 24V currents are operated via a coil. When the coil is electrically powered, a magnetic field is created that creates the force acting on the plunger inside the coils to cause the piston to move. Depending on the design of the valve, the piston acts either to open or close the valve. When the current is disconnected from the windings, the valves return to their original state.
See below, you can realize that
1) Valve body: bronze or stainless steel, plastic.
2) Fluid: liquid (water, oil) or gas (compressed gas, gas, etc.)
3) Empty axis pipe – No flow through.
4) Coil Casing (Used to protect the coil)
5) Coil coil (Coil magnet will generate the suction force)
6) Wires (can use voltage 220V, 24V, 110V)
7) An axis valve sealed (normal state spring 8 will impact sealed, help the valve in the closed state).
9) Fluid leakage through when valve opening
Basically, a solenoid valve will be constructed as above. However due to some special technical requirements. Such as working environment, temperature, pressure, flow through, materials. That some electromagnetic valves will be specially designed will be different than the above drawing.
There are two basic types of solenoid valves, there are: the normally closed solenoid valve and the normally open solenoid valve. In this article, we will briefly share with you the principle of operation of:
From here we can see that the principle of operation of the normally open solenoid valve (NO) will be similar to the normally closed electromagnetic valve.
With the continuous development of technology. As well as the automation of production in general and consumption in particular. The opening and closing of the piping equipment is also automatic and becomes urgent. Solenoid valves have been studied and produced for a long time, now the valve is more popular in Vietnam market.
To meet the increasing demand of the market, valve companies in Vietnam have been importing a variety of valves in time to meet the needs of diverse customers.
We will stop at here today, in the next post may be I will find out more about pros and cons of Solenoid valve. Wait me, OK! Thanh you!
