A pulse-controlled micro-power position feedback bistable electric control valve

Abstract

The invention discloses a pulse control type micro-power-consumption position feedback bistable-state electric control valve which comprises a valve body and a bonnet. A rotation magnetic switch structure, a position detecting structure, a magnetic clutch transmission structure and a sensor are disposed in the valve body. The rotation magnetic switch structure comprises a movable core component, a magnet component built in a movable core and a spring component, wherein the movable core component comprises the movable core, a movable core cover plate and a movable core drive plate, the spring component comprises an auxiliary spring disposed on the upper portion of the movable core and a main spring disposed on the lower portion of the movable core, and the magnet component comprises a main magnet disposed inside the movable core and an auxiliary magnet disposed inside the movable core drive part. The pulse control type micro-power-consumption position feedback bistable-state electric control valve has the advantages that the valve meets the requirements of low power consumption, position feedback, single signal control, free of external leakage and various working modes, and the valve is universally applicable to fluid pipeline systems requiring precise control or measuring.

Description

technical field [0001] The invention relates to the technical field of electric control valves, in particular to a pulse-controlled micro-power position feedback bistable electric control valve. Background technique [0002] At present, the electronically controlled valves commonly used in the market include: battery-powered solenoid valves, pulsed bistable solenoid valves, position feedback solenoid valves, and micro-motor-driven bistable solenoid valves. [0003] Battery-powered solenoid valve: double-coil design, the pull-in coil generates a strong enough electromagnetic force to overcome the spring force to make the seal connected to the moving iron core move to the target position; the holding coil generates a relatively small electromagnetic force to The state of the moving iron core remains unchanged; if the coil is not powered, the moving iron core returns to the initial position under the action of the spring force.
