Rotary self-hold type fluid flux electromagnetic valve

Abstract

The invention provides a rotary self-hold type fluid flux electromagnetic valve. A rotary valve body and a valve seat are coaxially arranged. A first valve hole and a second valve hole are arranged inthe valve seat and the valve body. A first electromagnetic pole end and a second electromagnetic pole end are opposite to a first angle and a second angle. A magnet is corresponding to an electromagnet. When forward current flows in a first coil, a first magnetic attractive force is generated by the first electromagnetic pole end and a first fixed magnetic pole end, and a first magnetic repulsiveforce is generated by the second electromagnetic pole end and the first fixed magnetic pole end and drives the valve body to the first angle. When reverse current flows in the first coil, a second magnetic attractive force is generated by the second electromagnetic pole end and the first fixed magnetic pole end, and a second magnetic repulsive force is generated by the first electromagnetic poleend and the first fixed magnetic pole end and drives the valve body to the second angle. When the valve body is arranged at the first or second angle and the first coil is not electrified, the first fixed magnetic pole end holds the first or second electromagnetic pole end, thus the valve body and the valve seat are fixed at the first or second angle, in a continuous on / off state, current does notneed to be continuously fed into coil winding to reach a self-hold effect, and the energy is saved.

Description

[0001] This invention claims priority 107112788 technical field [0002] The invention relates to a rotary self-holding fluid flow solenoid valve, especially a solenoid valve control technology that can achieve self-holding and energy-saving effects without continuous input of holding current to the solenoid valve winding during continuous opening or closing. Background technique [0003] Press, the known solenoid valve is indeed a very common fluid pipeline control device in electrical equipment or fluid control equipment. The solenoid valve mainly controls whether the electromagnet is excited or not by means of power-on or power-off, and then linearly drives the valve to open or close the channel, so that the fluid flow in the fluid pipeline can be controlled by opening and closing the channel of the solenoid valve or off. Although the known solenoid valve has the function of opening and closing control of the fluid pipeline; but, in the use of a normally open or normally...

Problems solved by technology

Although the above-mentioned patent can achieve the function of fluid flux control, it requires the configuration of multiple sets of solenoid valves and multiple sets of pipeline joints, which will not only increase the cost of parts, but also cause the fluid pipeline to be complicated due to the pipeline. It is inconvenient to assemble and increases the probability of pipeline failure.

[0005] In view of this, the technical maturity of solenoid valve products is still not perfect, and there is still a need for further improvement. Therefore, how to develop a solenoid valve technology that can realize the dual functions of self-sustaining energy saving and fluid flux control In fact, it has become a technical issue that relevant industry and academia are eager to challenge and overcome.
