Solenoid Valve Introduction : Working Principle, Application and Selection Points
- วาล์วเดลโก้
Solenoid valve is a common valve equipment in the industrial control system, the following วาล์วเดลโก้ will share the working principle of the solenoid valve, application scenarios and selection points.
Structure and working principle of solenoid valve
The valve body of solenoid valve is usually made of metal material with certain strength and sealing performance. The spool usually consists of a movable part with a sealing ring, which seals the flow of medium when the spool is in contact with the valve seat. The coil is connected to the power supply through a wire to generate a magnetic field that controls the movement of the spool. When energized, the coil generates a magnetic field, so that the spool is subjected to magnetic force, separated from the valve seat or contact, thereby controlling the flow of media. When the power is off, the magnetic field disappears, the spool returns to its original position due to the action of the spring, and the valve closes.
Application Scenarios of Solenoid Valve
- Automated production lines: solenoid valves can be used to control hydraulic or pneumatic equipment to realize the operation and control of automated production lines.
- Automotive industry: solenoid valves are used in the control system of automobile engines, such as fuel injection system, air conditioning system and braking system.
- Petroleum and chemical industry: solenoid valve is used to control the flow of liquid or gas in the pipeline, to realize the flow regulation, pressure control and fluid cut-off and other functions.
- Medical equipment: solenoid valves play an important role in medical equipment, such as ventilators, infusion equipment and hemodialysis machines.
- Air conditioning and refrigeration: solenoid valve is widely used in air conditioning and refrigeration systems, used to control the flow of refrigerant and pressure.
Solenoid valve selection points
- Working medium: first of all, we must clarify the working medium used, such as liquid, gas or steam. Different working media on the solenoid valve material, sealing performance and corrosion resistance requirements are different, so you need to choose the solenoid valve model suitable for the working medium.
- Working pressure: determine the working pressure range required by the system in order to select the appropriate pressure rating of the solenoid valve. Too high or too low a working pressure may lead to solenoid valve performance degradation or can not work properly. 3.
- Flow requirements: according to the flow requirements of the system to select the appropriate solenoid valve caliber and diameter. Too large or too small aperture may lead to unstable system flow or can not meet the requirements.
- Operating temperature: determine the operating temperature range of the system, select the solenoid valve materials and seals that can withstand the temperature range. Too high or too low a working temperature may affect the performance and life of the solenoid valve.
- Control mode: according to the control requirements of the system to select the appropriate solenoid valve control mode, such as direct-drive, guided or diaphragm type.
