Abstract

The invention discloses a miniature solenoid valve. The miniature solenoid valve comprises a valve body, a valve deck and a valve pin. The valve deck comprises air channels. The valve pin comprises a sliding sleeve, and a pair of permanent magnets with the poles arranged oppositely are arranged in the sliding sleeve. The drift diameter of the air channels ranges from 2.0 mm to 10.0 mm. The permanent magnets instead of a mechanical spring are adopted in the valve pin, the poles of the permanent magnets are arranged oppositely, the driving force of an electromagnetic switch is greatly increased, the sensitivity to disconnection or connection of the air inlet channel and the air outlet channel by the solenoid valve is higher, and reversing of the electromagnetic switch is more flexible and faster. The drift diameter of the air channels ranges from 2.0 mm to 10.0 mm, and therefore the area of the air channels is enlarged by 25-100 times than that of an existing solenoid valve, and the application range of the miniature solenoid valve is greatly expanded.

Description

technical field [0001] The invention relates to an electromagnetic valve, in particular to a miniature electromagnetic valve. Background technique [0002] Micro solenoid valve is a key actuator in a widely used automation control technology. At present, due to design principles, structures and manufacturing reasons, the micro solenoid valves on the market generally have a small flow capacity and cannot adapt to users. Wide range of needs, large working current, easy heating of the coil, and inability to work for a long time and other defects. [0003] The patent with the application number 201120174797.9 discloses a low-power miniature solenoid valve, which improves the shortcomings of the above-mentioned traditional miniature solenoid valves, such as: the diameter of the air inlet hole of the valve body is enlarged from the original 0.7mm to 0.7mm -2.0mm, so that the flow rate of the medium that can pass through the micro solenoid valve is greatly improved, but compared w...
