Induction machine driving type electric control valve

Abstract

The invention discloses an induction machine driving type electric control valve. The induction machine driving type electric control valve comprises a valve body component, an induction machine, a speed reducing mechanism and a rotary valve disc device, wherein the induction machine comprises a stator and a rotor. The induction machine driving type electric control valve is characterized in that the stator is fixed to the outer wall of the valve body component, and the rotor is installed in the valve body component; when the induction machine is electrified, a revolving magnetic field generated by the stator interacts with a magnetic field generated by the rotor, so that the rotor rotates; and the rotor drives the rotary valve disc device to rotate through the speed reducing mechanism. The induction type driving type electric control valve has the advantages of multiple functions, wide application, long service life, energy conservation and low noise.

Description

Technical field [0001] The present invention relates to an induction motor drive type electrical control valve. Background technique [0002] At present, the electric control valve used at home and abroad, such as the pilot four-way reverse valve, electromagnetic one-way valve (switch valve), electromagnetic switching valve, is electromagnetic structure, that is, when the coil is connected, the iron core and the armature Magnified, two magnets which are opposite to polarity, which produce electromagnetic suction. When the suction is larger than the retrogenous force of the spring, the armature begins to move toward the core direction. When the current in the coil is less than a certain or interrupt power supply, the electromagnetic suction is smaller than the reaction force of the spring, and the armature will return to the original release position under the action of the reaction force. [0003] This structure, from the perspective of function: only two states in the operation ...

AI Technical Summary

Problems solved by technology

[0003] This structure, analyzed from the functional point of view: in the action control, only two states of opening and closing can be realized, without the function of adjusting the flow; from the point of view of energy saving: to realize a state or function mode, the coil needs to be energized; from the perspective of product life Angle analysis: such as on-off valve or switching valve, if the operating frequency is relatively high, it is easy to cause loss of internal parts and poor contact; from the perspective of product environmental protection: if the operating frequency of the solenoid valve is relatively high, continuous electromagnetic noise will be generated
