Description

Technical Field

[0001] This invention relates to the field of solenoid valves, and more particularly to a plate-mounted, non-magnetic ring, two-position, three-way high-speed solenoid valve. Background Technology

[0002] Two-position three-way solenoid valves are a commonly used fluid control valve. They control the movement of the valve core by the engagement and disengagement of an electromagnet, thereby controlling the direction of fluid flow.

[0003] Most existing domestic and international solenoid valve products of the same type use platform or basin-type solenoid structures. Because this type of solenoid structure uses a magnetic circuit breaker structure, the external mating parts of the moving iron (moving part) are usually machined into independent parts similar to bearings, and air is used in the middle to act as a magnetic circuit breaker, forcing the magnetic field to pass through the moving iron (moving part) to the maximum extent to obtain a large electromagnetic force. However, this design has high requirements for product assembly and is prone to solenoid valve jamming. During the movement of the solenoid valve moving iron, it will be subjected to the lateral attraction of the stationary iron. At this time, if the coaxiality of the external mating parts of the moving iron is not good, it is easy to swing to the side and jam, causing the product to fail to work properly.
