What is the specific working principle of pulse valve coil?

The working principle of the 24V pulse valve coil mainly involves the interaction between electricity and magnetism. Here is a detailed explanation:

• Electromagnetic induction: The pulse valve coil is essentially a solenoid, which is made of many turns of copper wire wound around a core. When a 24V alternating current is applied to the coil, according to Faraday’s law of electromagnetic induction, an alternating magnetic field is generated around the coil. The strength and direction of this magnetic field change with the frequency of the alternating current.
• Magnetic force generation: The core inside the coil is usually made of a ferromagnetic material such as iron. When the coil is energized, the core is magnetized by the magnetic field, which significantly enhances the magnetic field intensity. This strong magnetic field exerts a magnetic force on the movable parts of the pulse valve, such as the armature.
• Valve actuation: The magnetic force causes the armature to move. When the current is turned on, the magnetic force attracts the armature, which in turn opens the valve to allow the fluid (gas or liquid) to pass through. When the current is cut off, the magnetic field disappears, and the armature returns to its original position under the action of a spring or other restoring force, closing the valve and stopping the fluid flow. By controlling the on – off time of the current, the opening and closing time of the pulse valve can be accurately controlled, thereby achieving precise control of the fluid flow rate and pressure in the filtering and purifying device.
