What is the difference between solenoid valves and ordinary valves?

Date：2024-06-11

1. Working principle:
The working principle of the solenoid valve is based on the principles of electromagnetism and fluid mechanics. When the coil of the solenoid valve is energized, the current will generate a magnetic field in the coil, which will cause the valve core to move, thereby changing the channel state inside the valve body. Specifically, when the coil is energized, the magnetic field generated will attract or repel the valve core, causing it to open or close the channel, thus controlling the flow of fluids (such as water, gas, oil, etc.). This control method based on electromagnetic force enables solenoid valves to quickly and accurately control the flow of fluids, so it is widely used in various industrial and mechanical equipment.

2.Control method:
The control method of the solenoid valve is mainly to control the position of the valve core by adjusting the input current or voltage, thereby controlling the flow of fluid. By changing the power supply voltage or current of the solenoid valve, the movement of the valve core can be accurately controlled, thereby achieving precise regulation of fluid flow. In addition, different control modes can be realized by controlling the switching time and frequency of the solenoid valve, such as normally open, normally closed or periodic opening and closing, etc., to meet the needs of different application scenarios.

3. Applicable scenarios:
Solenoid valves are suitable for various systems and equipment that require automated control, such as hydraulic systems, air compression systems, automated production lines, etc. Because solenoid valves have precise control capabilities and reliability, they are widely used in situations that require high-precision control. For example, in automated production lines, solenoid valves can achieve precise control of actuators such as hydraulic cylinders and pneumatic actuators, thereby realizing automated production and processing of products.

4.Response speed:
The response speed of solenoid valves is usually fast and can achieve response times of milliseconds. This mainly depends on the design and manufacturing process of the solenoid valve, as well as factors such as the size and frequency of the input current. By optimizing the design and selecting appropriate materials, the response speed of the solenoid valve can be further improved to meet the needs of systems and equipment that require high response speed. Therefore, solenoid valves play an important role in applications that require rapid and accurate control of fluid flow.
