Aboutsolenoid valveHow much do you know? Have you really gained a thorough understanding of fluid control components that are widely used in the industrial control industry? What is an electromagnetic valve? This article allows us to understand together. Electromagnetic valve is an automation basic component used to control fluids and belongs to actuators; Not limited to hydraulic and pneumatic. Electromagnetic valves are used to control the direction of hydraulic flow, and the mechanical devices in factories are generally controlled by hydraulic steel, so electromagnetic valves are used. The solenoid valve has a sealed chamber with through holes at different positions, each leading to a different oil pipe. The middle of the chamber is the valve, and there are two electromagnets on both sides. The magnetic coil on one side will attract the valve body to the other 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 oil pressure will push the piston, which in turn drives the piston rod, which drives the mechanical device to move. In this way, the mechanical motion is controlled by controlling the current of the electromagnet.

solenoid valveThe selection process is quite complex, as solenoid valves have never been included in textbooks for the field of self-control. Many people believe that the selection process is simple, and only experienced designers know that this small device should be taken seriously. There are dozens of types of solenoid valves based on their structure and principle, and considering various technical parameters, there are up to tens of thousands of cross combinations. Design and procurement personnel have gradually learned to make the right choices amidst the dazzling array. In addition to collecting and researching sample data, they also directly negotiate with manufacturing companies, personally inspect the economic and technological strength and technical guarantee capabilities of production plants for large or important items, and go deep into their original users to understand the usage of products on site. Nowadays, everyone has to do financial accounting, but this is by no means a simple comparison of quotes. In addition to performance factors such as safety, applicability, durability, and aesthetics that affect price, it is also related to the performance and cost of the entire self-control system and piping system, which has become a comprehensive discipline.

solenoid valveWhat are the main characteristics of? Let's take a look. Internal and external leakage is a factor that endangers safety. Other self-control valves usually extend the valve stem and control the rotation or movement of the valve core through electric, pneumatic, or hydraulic actuators. All of this needs to solve the problem of long-term leakage of valve stem seals; Only solenoid valves use electromagnetic force to seal the iron core inside the magnetic isolation sleeve, without dynamic sealing, so external leakage is easily blocked. Electric valve torque control is not easy, which can easily cause internal leakage and even break the valve stem head; The structural type of solenoid valve is easy to control internal leakage until it is reduced to zero. So, the use of solenoid valves is particularly safe, especially suitable for corrosive, toxic, or high and low temperature media.

solenoid valveThe structure itself is simple and the price is low, making it easier to install and maintain compared to other types of actuators such as regulating valves. More significantly, the composed self-control system is much simpler and priced much lower. Due to the fact that the solenoid valve is controlled by switch signals, it is very convenient to connect with industrial control computers. In today's era of widespread computer use and significant price reductions, the advantages of solenoid valves are even more apparent. The response time of solenoid valves can be as short as a few milliseconds, and even pilot operated solenoid valves can be controlled within tens of milliseconds. Due to its self-contained circuit, it responds more sensitively than other self-control valves. A well-designed solenoid valve coil has low power consumption and is considered an energy-saving product; It can also automatically maintain the valve position by triggering the action, without consuming any electricity during normal operation. The electromagnetic valve has a small external size, which saves space and is lightweight and beautiful.

solenoid valveUsually there are only two states for the valve core, which can only be in two extreme positions and cannot be continuously adjusted, so the adjustment accuracy is still limited to a certain extent. Electromagnetic valves have high requirements for the cleanliness of the medium, and are not suitable for media containing particles. If impurities are present, they must be filtered out first. In addition, viscous media are not suitable, and the viscosity range of media suitable for specific products is relatively narrow. Although solenoid valves have inherent shortcomings, their advantages are still very prominent, so they are designed into a variety of products to meet different needs and have a wide range of applications. The progress of solenoid valve technology also revolves around how to overcome inherent shortcomings and better leverage inherent advantages.
