Micro-valve and micro-solenoid valve have significant differences in design and function, mainly reflected in the following aspects:
First, the working principle
Micro gas valve: usually refers to the valve used to control the flow of gas, such as the micro gas check valve. It uses a simple and effective design to control the direction of gas flow through a removable valve disc. When the pressure of the gas flow exceeds the opening pressure on the valve disc, the valve disc will automatically open to allow the gas to pass through; When the pressure of the gas flow is lower than the closing pressure on the valve disc, the valve disc will automatically close, preventing the gas counterflow.
Micro solenoid valve: The electromagnetic force is used to control the switch of the valve. Its basic structure includes valve body, valve core, coil and other components. When energized, the coil will generate a magnetic field, so that the valve core is moved by the magnetic force, thus changing the opening state of the valve; When the power is off, the spool will be restored to its original position by the action of the spring, thus closing the valve.
Second, structure and material
Micro-valves: The design is very precise and usually made of high-strength materials such as stainless steel or copper alloys to ensure their durability and long life. In addition, the micro-gas check valve has a sealed design to prevent gas leaks or outside contaminants from entering.
Micro-solenoid valve: In order to achieve the requirements of lightweight, small size, fast response, low power consumption and high reliability, electromagnet and valve body are usually integrated design. Its main components include valve body, coil, permanent magnet, valve seat, valve core seal block, armature, spring and so on. The electromagnetic structure of the solenoid valve may adopt a spiral tube type to improve suction and stroke.
3. Application scenarios
Micro-valve: widely used in all walks of life, especially in applications that require precise control of the direction of gas flow. For example, in medical equipment, it is often used in equipment such as ventilators and gas analyzers; In the industrial field, it is widely used in gas delivery systems, compressors and other equipment.
Micro solenoid valve: also has a wide range of applications, including medical equipment (such as ventilators, infusion pumps, etc.), industrial automation (such as hydraulic systems, pneumatic systems, etc.), experimental instruments (such as liquid chromatographs, gas chromatographs, etc.), environmental monitoring (such as gas analyzers, water quality monitors, etc.) and the automotive industry (such as engine control systems, transmission control systems, etc.). The micro-solenoid valve can realize the precise control and adjustment of the fluid, with high control accuracy and reliability.
Fourth, performance characteristics
Micro-valves: Known for their high efficiency, reliability and stability to ensure valve performance under different pressure conditions.
Micro solenoid valve: it is favored for its small and lightweight, high efficiency and energy saving, high reliability and other characteristics. In addition, the micro-solenoid valve can also provide a variety of interface forms and control methods to meet the needs of different application scenarios.
