dc one-way air valve for massage equipments

Mini Air Valve is a device used to control gas flow and is widely used in industrial automation control systems, medical equipment, household appliances and other fields. Its basic working principle is to control the on-off gas flow by adjusting the position of the valve core to adjust the flow rate and pressure. This document will introduce in detail the working principle of the Micro Solenoid Air Valve, including the driving mechanism, valve structure, flow control, opening and closing process, and performance characteristics.

Driving mechanism

The driving mechanism of Mini Solenoid Air Valve usually uses electromagnetic force, air pressure or spring force. Among them, electromagnetic drive is the most commonly used method. The magnetic field generated by electrification attracts the movement of the valve core, thereby changing the on-off state of the gas channel. Pneumatic drive uses the pressure generated by an external air source to push the valve core to move, while spring drive uses the elastic force of the spring to push the valve core to move.

Valve structure

The structure of mini air release valve usually includes valve body, valve core, spring, sealing gasket and other parts. The valve body is the shell of the micro air valve and is used to fix and install other components; the valve core is the core component that controls the gas flow and can move up and down or left and right; the spring is usually used to provide a reset force to return the valve core to its original position; sealing The gasket is used to seal the gas channel and prevent gas leakage.

Flow control

The flow control of the Normally Closed Air Valve mainly depends on the opening size of the valve core and the cross-sectional area of the gas channel. When the valve core is opened, the cross-sectional area of the gas channel increases and the gas flow rate increases; when the valve core is closed, the cross-sectional area of the gas channel decreases and the gas flow rate decreases. By adjusting the opening size of the valve core, precise control of the gas flow can be achieved.

Opening and closing process

The opening and closing process of mini air control valve is usually controlled by a driving mechanism. In the case of electromagnetic drive, when the coil is energized, a magnetic field is generated to attract the valve core to move and open the gas channel; when the coil is de-energized, the magnetic field disappears and the spring force resets the valve core to close the gas channel. In the case of air pressure drive, the external air source controls the movement of the valve core by adjusting the pressure, thereby realizing on-off regulation of gas. In the case of spring drive, the elastic force of the spring pushes the valve core to move, opening or closing the gas channel.

DC micro solenoid air valve have the following performance characteristics:

1. Compact structure, small size, light weight, easy to install and use.

2. The reaction speed is fast and the gas channel can be opened and closed quickly.

3. The control accuracy is high and precise gas flow and pressure regulation can be achieved.

4. High reliability and can work stably in harsh environments.

5. Long service life, subject to strict quality control and durability testing.
