Embodiment 1

[0032] In a specific embodiment, the electromagnetic mechanism provided by the present invention can be realized in the following structural manner.

[0033] The double-coil bistable electromagnetic mechanism of the sealed conical armature provided by the invention, which can be applied to many fields such as valve control, has large stroke, high holding force, large output force and low power consumption. The design of the mechanism is suitable for application in valve control systems For example, in air conditioners, oil pipelines, heating pipelines and other equipment, it has the characteristics of large stroke, large output force, positive and negative pulse drive, bistable permanent magnet circuit maintenance, simple pipeline, low cost, and small size. After the electromagnetic system, the force change can be quickly adjusted by replacing the permanent magnet (within the magnetic saturation range), and multiple adjustments of the permanent magnet and part size can also be ...

Embodiment 2

[0040] In a specific embodiment, the specific working process of the electromagnetic mechanism provided by the present invention can be carried out in the following manner:

[0041] like Figure 4 , the lower end of the armature a1 is closed and is in the release position. The lower end surface of the armature a1 and the static iron core a6 form a working air gap 1; the coil one a7 and the coil two a8 are wound on the bobbin a9, the tapered surface of the armature a1 and the upper yoke a5 A working air gap 2 is formed on the upper pole surface. The inner surface of the permanent magnet a2 and the outer surface of the armature a1 form a non-working air gap 3. At this time, the magnetic flux of the permanent magnet magnetic circuit without current applied to the coil 1 a7 and coil 2 a8 has two closed magnetic circuits, and the magnetic circuit 1: the permanent magnet N pole - non-working air gap 3 - lower half of armature a1 - working air gap 1 - static iron core a6 - bottom of...

Abstract

The invention provides a double-coil bistable-state electromagnetic mechanism provided with an armature with a sealing conical surface. The armature with the conical surface is used as the core structure of the electromagnetic mechanism, so that the initial output force is increased, and the retention force of the closing side is also increased. The structure that two coils are connected in seriesis adopted; in the closing process, the lower coil is used for counteracting the permanent magnetic flux on the lower portion, and the upper coil is used for increasing the permanent magnetic flux onthe upper portion; and in the releasing process, the upper coil is used for counteracting the permanent magnetic flux on the upper portion, and the lower coil is used for increasing the permanent magnetic flux on the lower portion. By adoption of the double-coil bistable-state electromagnetic mechanism provided with the armature with the sealing conical surface, the defects of short stroke, monostable retention, high power consumption and the like of traditional electromagnetic valve control are overcome; and the double-coil bistable-state electromagnetic mechanism provided with the armaturewith the sealing conical surface has the advantages of small size, large output force and retention force, bistability, permanent-magnetic loop retention, energy saving and the like.

Description

technical field [0001] The invention relates to the application field of electromagnetic valves, in particular to the design of an armature-sealed bistable electromagnetic mechanism. Background technique [0002] With the rapid development of China's economy, solenoid valves, as an actuator of automatic instruments, have seen a sharp rise in usage in recent years, and are widely used in various fields such as machinery, petrochemicals, electric power, and national defense research. At present, most of the valves on the market are controlled by hydraulic valves, which have short strokes, monostable state maintenance, high power consumption, and need to be powered all the time, which does not save energy. [0003] In view of the above problems, a permanent magnet bistable electromagnetic mechanism is provided, which increases the stroke and output force, and adopts forward and reverse pulse drive. The pipeline is simple, the cost is low, the volume is small, and the expandabil...
